The problems of energy supply systems and sanitation

2011-04-07T11:06:00.000-07:00

In the total energy consumption in water supply and sanitation in human settlements and industrial facilities for more than 90% are pumping systems for natural, potable, industrial and waste water to supply reagents and air. Due to rapidly rising prices for gas and oil in all countries urgently raises questions of energy efficiency of water supply and sanitation, as well as their elements.

This explains the stringent requirements of international and European standards (ISO and EN) as to efficiency and quality of pumping equipment. Thus, the international association of European manufacturers of pumps Grundfos up15-29su introduced a new labeling scheme approved pumps. Underlying the need for such labeling lay the fact that there are large differences in energy consumption and different levels of technological development in the East and West Europe. Only 20% established in the European Union, pumping systems have been optimized for power consumption [1].

The scheme of energy labels is focused on the potential energy savings associated with a growing international scientific and technological progress. This scheme is described in the voluntary agreement, entitled "Industrial undertaking", promulgated by the Europump. Currently, this agreement was signed by four European manufacturer of pumps, the leading positions among which belongs to the concern Grundfos. These industrial obligations include a unified classification scheme based on energy efficiency index (EEI - Energy Efficiency Index), formed on the basis of the annual load profile and distributed systems with almost the same load profile. The average pump is placed in category D and E.

Little giant sump pumps: Some more information and types

Signing of an agreement on energy labeling pump manufacturers undertake to mark all future pumps Acting as the territories of Canada and most countries of the CIS Building Regulations (SNIP), standards, specifications and other normative and technical documents for design and construction of the former Taco 007 IFC Canada do not meet modern requirements and conditions. They require a fundamental change certain provisions and to make new demands.

In particular, the current GOST 10428-89. "Little Giant 6-CIA pump units for Circulating borehole for water. The basic parameters and dimensions" is outdated in terms of basic parameters and dimensions for the Taco 007 boreholes, where the best foreign models outperform the multiple indicators.

Little Giant 5-msp – An Outline

For example, in Table 4. GOST 10428-89 is specified pumping unit Little Giant 4 with a capacity Q = 6,5 m3 / h with a head of H = 4 bar, efficiency = 38%, diameter of 95mm aggregate. With the same parameters of Q and H SQE pump has a diameter of 74 mm and an efficiency of 44%. Similar comparisons can be reduced and other pumping units. The manual for SNIP 2.04.02-84 design automation and control systems, water supply indicated contrary to the fundamental principle of saving any Taco 007-F5, install a good pump to your piping system, which "usually an automatic control system with adjustable drive advisable to use a pumping plant is relatively high power (75-100 kW and above ). " At the same time, all the pump manufacturers provide integrated automation systems for all types and sizes of pumping equipment.

Little Giant Pumps, developed by experts of the Little Giant - is a versatile pumping units used for drainage of industrial and domestic waste water, fluid handling to wastewater treatment plants, pumping out rain and surface water. With a special one-piece design with different types of impellers, Little Giant pumps can pump liquids containing higher amount of abrasive and fiber components.

Little Giant Co. has produced the first models of pumping equipment in 1989, and, as evidenced by positive feedback from consumers, the use Little Giant Effluent Pumps leads to an increase in productivity pumping stations with a significant decrease in the cost of their care. Moreover, the effectiveness of sanitation increases not only the replacement of obsolete units, but also during the installation of pumping equipment series Little Giant Sewage Pumps instead of modern foreign-made pumps.

Among the large selection available on the market of imported plumbing pumps, and many are indeed examples of high-end technology. That's just the level of their suitability for use in the Russian conditions is extremely low so that it is almost always expensive equipment operate smoothly for a long time and at the proper level.

Broken snail, broken impellers, a burned-out pump rotor, worn hydraulics or ongoing mechanical seals - fairly common types of injuries Grundfos pumps, after a short service at the local water utility companies. Very often, the discrepancy of sewer systems to European standards, regulations, specifications, etc. is the reason for denial of service centers to repair the pump. And all that remains is the owner of a failed pump - is the purchase and installation of spare parts, often at a cost of only slightly inferior to the new unit. And in those rare cases where all conditions of operation can be aligned to the required standards and in the presence of all necessary additional equipment, such as the shield of automatic control, maintenance of imported pump still leaves a lot of money.

The reason is the high costs and the price of bearings, mechanical seals, gaskets and other, requiring the timely replacement of parts, and that the installation, repair and maintenance of Grundfos pumps must be carried out by experienced qualified professionals, whose content the state enterprises are also expensive. It turns out that the purchase of imported plumbing pump - just the beginning in a series of upcoming expenses.

That's why today is such a popular low-cost domestic pumps, among which pumps Little Giant highlighted a number of its advantages. Compared with pumps from other Russian producers, such as pumps Circulator Pumps, Transfer Pumps, Condensate Pumps not afraid of flooding - very common in sewers. Besides pumps "Little Giant" structurally suited to automation, which greatly simplifies their maintenance. Which can not be said of most domestic units, to control the operation of which requires the presence of the operator and periodic adjustments and debugging equipment.

Moreover, the inability to automate starting the engine to open the valve inevitably leads to water hammer every time you start and stop the pump, and the lack of an automatic fluid level check - to the rapid deterioration of the impellers, check valves, gate valves, pressure gauges, coupling, pipeline.

Avoid these problems and allows the equipment pump control panels, through which plumbing units Little Giant is a complex automated, self-oriented in a liquid that can track and maintain the water level at a given value. Self-diagnostic system monitors the pump pump rotor windings changes in temperature, humidity degree of isolation and, in case of deviation from the allowable loads and to detect leaks, displays the data on the bulletin board. Ease of operation of pumps Irtysh is also achieved through plug-type connections, allowing quick and easy enough to dismantle the unit for maintenance and set it back in line.

Summing up the above, it should be noted the following advantages, which ensures operation of plumbing pump Irtysh:
1. The small cost to purchase the pump.
2. Reduce operational and maintenance costs.
3. Reduce time spent on maintenance.
4. Compactness of the single-warhead Little Giant Sump Pumps to reduce the volume of construction of sewerage systems.
5. The process of pumping effluent becomes completely automated. There is no risk of accidental flooding.
6. Increased energy efficiency pumping stations: first, due to optimally matched equipment, and secondly, due to improved flow-through unit.
7. The broad scope - from pumping rainwater to the pumping of clean water.
8. Environmentally friendly use of running Little Giant Utility Pumps provided a low level of noise, vibration and the lack of heat.
9. Possibility to order the pump with the necessary operating parameters corresponding to specific technical requirements.
10. Finally, the Little Giant Submersible Pumps - a modern high-performance, high quality and reliable equipment, adapted to work in the USA context.

Pumps and pump equipment

To answer these questions must consider the characteristics of pump units in a group of parallel connected pumps. Work the pump unit in the group is fundamentally different from the conditions of a single unit. Maximum supply a single unit due to the minimal hydraulic resistance pipeline and the correct choice of pump shift it to the high values of the innings is impossible. Therefore, the operating point at the same time is a boundary that prevents the displacement unit in a zone of possible occurrence of cavitation and overload the pump rotor drive.

When working in a group of any change in status of any unit, through its inclusion in the closed (shutdown) or regulating the speed of the impeller changes the state of the system. In this case, a redistribution of load between the units, which can lead to an increase in supply of one group of units with the risk of getting into the zone of cavitation and overload and Little Giant pump Little Giant pumps Little Giant submersible pumps drive the other group with the risk of hitting them in the region of instability and surging.

For this purpose, we developed a mathematical model of the pumping unit with adjustable drive and is composed of a special computer program «SKAN-NAS», allowing to scan characteristics of practical interest range of loads. At the same time as the initial data about the pump is its pressure and cavitation characteristics, as well as the characteristic efficiency. As background information in the program also introduced the following parameters: power of the Taco drive, the difference between the elevations of water level in receiving tank and the axis of the impeller, the dependence of head loss in the suction line of the pump from its filing, the maximum and minimum allowable values of the frequency of rotation (K = nm / nh, where nm - the current speed of the impeller, nh - nominal), the minimum acceptable efficiency values.

In any case, you have to disassemble the pump and remove the shaft obstruction. The special design of hydraulic parts with advanced impeller pumps Grundfos company, allowed not only to once and for all get rid of this problem, but also to ensure greater protection of the impeller from the effects of friction particles in suspension and shock loads. In addition, these pumps are used alloy impellers made of different materials, which when exposed to shocks are more reliable than welded.

The presence of such features as double mechanical shaft seal in oil-filled chamber and the oil-filled Grundfos 15-58 pump rotor, cooling pump ensures even when dipping it into liquid in less than half.

A distinctive feature of the Grundfos 15-42 pumps is the presence of grinding mechanism on the input. These pumps are specifically designed for pumping plumbing and liquids containing long fibrous particles. They are able to grind all the suspended inclusions, such as hair, tissue, pulp, down to individual pieces of plastic and wood, in a gelatinous mass. Yet they have higher pressure head characteristics, since they can use smaller diameter plumbing pipeline without any danger of clogging.

On these design features can be said for quite some time. Unfortunately, many sellers, in addition to data listed on the label of the pump (which is mainly flow, pressure and power), they do not know such technical subtleties and distinctive features of some pumps from others.

Overabundance of pumping equipment on the USA market, a wide range of cheap pumps, sometimes does not even have an elementary thermal protection, are pushing to buy a cheap pump. And in a short amount of time you are experiencing problems with repairs and service. It takes time, money, and who knows how long this pump will run until the next repair. Much calmer, pay once more, to get buy really high quality and reliability.

Buy now pump there is no difficulty: the shops and firms involved in trafficking of pumping equipment quite a lot. It only remains to sort out a number of questions: What pump for its purpose, its scope, design features and characteristics. After that, we can assume that you are ready to choose the pump that best meets the specific domestic goals.

Consider some of the technical details of the example pump company Taco, offering a wide range of pumping equipment to meet the needs of any customer such as: Taco 007, Taco 009, Taco 0013 and other circulators.

Thus, small portable pumps Taco in plastic made from corrosion-resistant materials and have a ceramic shaft, which ensures long-term operation and reliable operation of the pumps in aggressive water. The presence of plug connectors between the pump rotor and supply cables prevents the failure of the pump in case of suspending him for the Taco cable.

Pump rotor connection to the network

2010-11-12T07:34:00.000-08:00

To connect to a network of Taco penciled him a wire or cable is cut and attached to the ends of the excretory or terminal screws in the inlet box. Some types of pump rotors have the box for fixing and commissioning of cables, steel pipes, metal hoses and other cable carve and finish steel pipes, flexible metal hose, etc., outside input boxes can not, because the ends of wires or cables in this case will be protected and can be damaged. Explosion-proof Taco pump rotors are connected to the network by entering into a box of wire and cable cross-section of 25 mm2 with a rubber or paper insulation.

If you connect a cable, whose cross section greater than 25 mm2, in front of the pump rotor install a special adapter box, which operates cable preparation. Wires and cables with a single-current-carrying conductors attached to the terminal screws of the Grundfos pump rotor directly to the inlet box (using bent at the end of the vein rings), and the wires and cables with stranded conductors supplying tips, fixed on the veins pressing or soldering. Tip and ring wear on the screws, opening the box and tighten the two nuts and washers, making sure the reliability of mounting screws and contact the correct jumper settings, connecting pump rotor windings in a star or triangle, depending on the rated voltage of the pump rotor and the network. Then the inlet box closed with a lid or cover to avoid accidental touching of naked, although isolated, conductors, and also keep water and foreign objects on them.

Taco 006 - high-pressure pump

2010-11-12T07:26:00.000-08:00

These pumps are typically multi-stage. Intensity of the pump depends on the size of the impeller, and other factors. Head in Circulating pumps of high pressure is achieved by using multiple impellers installed in series. Kinetic energy is converted into pressure in the working part, and partly rectifying apparatus.

Due to the possibility of varying the number of stages Taco 006 pump high pressure develops a higher pressure than low pressure single stage Circulating pumps.

Some pumps are up to 20 degrees. Thus, they can provide pressure up to 250 m. Almost all of the Taco 006 pump pressure, which we have described belong to the family of Dry pump rotor. Nevertheless, in recent years manufacturers successfully equip their engines with wet rotor.

Special instructions for block pumps
• Block pumps should be installed on the respective bases or brackets.
• Installation of block pump, at which the pump rotor and terminal box facing down, is not allowed. All other mounting methods are considered acceptable.

Mechanical seals

The basis of design of the mechanical seal are two rings with carefully polished surfaces. They are pressed together by a spring, and work together. CTS are dynamic seals and are used for sealing a rotating shaft in a fluid at high operating pressures. Grundfos is composed of two highly polished wear rings (for example, silicone or graphite), which are pressed together by axial forces.

One ring (dynamic) rotates with the shaft, while the other ring (static) still fixed into the body. Between the sliding surfaces a thin film of water that serves as lubrication and cooling. Depending on the mode of operation of the pump are several possible types of friction mating surfaces: a mixed friction, boundary friction or dry friction, the latter (which occurs at no lubricating film) causes environment destruction of the surfaces.

The service life depends on operating conditions such as composition and temperature of the working fluid.

Mechanical Seals

The materials for seals use high quality yarn from synthetic fibers such as Kevlar ® or Twaron ®, PTFE, porous graphite yarn, yarn of synthetic mineral fibers and natural fibers such as hemp, cotton or ramie.

Material for the seals is available in the form of threads or compacted coils in dry form or with special impregnation depending on the destination. If the material is purchased in the form of threads, you must first form a ring and give it shape. Then, the ring gland is wrapped around the pump shaft and tightened using crimp sleeves.

Circulating Pump Installation

2010-11-12T07:13:00.000-08:00

In installations where the level of fluid intake is below the axis of the circulator pump used to fill in two ways:
1) in aggregates of a small filing with the diameter of the suction pipe of 250 mm at the end of her under the water level have a foot valve. In this case, make the filling through a funnel and a crane at the top of the pump casing from the PEX Plumbing system or special filler tank;
2) in the aggregates with d> 250 mm receiving valves do not put produce and fill with suction air from the pump is a special expansion pump (commonly used types of Grundfos pumps and Taco, creating a expansion to 97%).

If there is contamination of the liquid intake funnel on the suction tube is combined with a slit or a strainer. Control over the operation of the pump is over the testimony of the gauge and pressure gauge attached to the suction by the discharge nozzle, flow measurement is made on the flow-meter mounted in the pump discharge line.

So how about a load of the pump can be measured by manometer readings, are often reluctant to install meters on each pump and have a meter on the common plumbing pipeline, controlling for his testimony filing unit as a whole. As the flow meters are used diaphragms, Venturi tubes and wing water meters. Power expended by the unit, is determined by the voltmeter, ammeter or wattmeter, disposable on an Taco board assembly cli install.

To start the pumping unit should produce preliminary tasks: to ensure free rotation of the shaft, check the tap and manometer gauge, fill pump and suction pipe, open the flow of cooling water into the bearings (in units with a cooled bearings), to check the position of the oil in the bearings (at bearings lubricated). Valve on the discharge plumbing pipeline Circulating pump during start-up must be closed (for n <250).

Start the pump is as follows: turn on the motor and speed it is brought to normal, slowly open valve on the pump discharge nozzle to achieve the required filing date; open valves that lead to the cooling water pump seal. When the pump should monitor the temperature of the bearings and the motor housing, which under normal circumstances should not exceed 60 ° C, the presence of oil in the chamber bearing (with oil lubrication), the density of glands (tightening of the packing is considered normal if he misses a few drops of water and temperature it is low).

Stop pumping unit is closing the valves on the discharge pipe, turn off the engine, close the valve on the suction tube and the cooling off seals and bearings). Start, the service at work and stop assemblies considerable power necessarily governed by special instructions. Special instructions subject to the exploitation of nutrient pumping units of steam boilers and pumps for hot liquids.

With modern technology development of automatic process control automation of pumping units is not difficult. Automatic pump control provides the following operations:
1) preparation of pumps to start, is to monitor the position of valves and pumps filled with liquid;
2) starting and stopping of pumps depending on the flow required by customers;
3) Stop the pump at fault it and start another pump to replace a faulty;
4) protection against overheating, seals and bearings;
5) the protection of hydraulic pumps, it becomes impossible to start the pump, not filled with fluid.
In developing the scheme of automation and protection of pumps may be provided for the necessity of pumping unit for the intended program. Automation improves the efficiency and reliability of the pumping unit, reduces the number of attendants.

Plate heat exchangers

2010-10-20T09:04:00.000-07:00

Plate heat exchangers are devices, heat exchange surface which is formed of thin molded plates with a corrugated surface.

Workspace in a heat exchanger are moving in the slot channels between adjacent plates. Channels for the heating and the heated coolant alternate.

The simplest heat exchanger consists of at least three plates, which form two channels: one for heating the coolant, the second for heating. Corrugated surface of the wafer increases the flow turbulence environments and increases the heat transfer coefficients. Sizes, shapes and surface profiles of the plates varied. Of the heat transfer plates, the main flue heat exchanger, collect the package. In this case, each successive plate is rotated 180 ° relative to adjacent, creating a uniform grid of points of intersection and mutual support corrugation peaks. Between each pair of adjacent plates formed a slit channel of complex shape, which takes place and working environment. Fluid motion in them makes the spatial three-dimensional winding movement, at which the flow turbulence. Corner holes for the passage of the working environment are in the form, reducing the hydraulic resistance at the channel entrance and exit, reducing sediment in these areas and allowing more efficient use of the entire area of the plate for heat exchange.

Frame system, which set the plate, base plate is formed, the upper and lower booms, enshrined in the base plate and supported the stand.

Practical advice for brass valve installation

2010-09-22T14:02:00.000-07:00

The role of substance that fills the thermostatic element is very significant bellows with gas filling have a large ball valve. They provide the maximum increase in the working volume of the bellows, and therefore the working stroke the brass ball valve at 1 "C. So, for example, when the temperature is lowered by 1" with respect to a given at the thermostatic element of the cone valve RT with the gas filling will rise above the saddle higher than in the case of liquid, oil or paraffin. Increased stroke valve for 1 "deals, as is known, more precise control characteristics and the bandwidth of the ball valve, and also provides less plugging of the valve.

The design of RT for two-pipe heating systems should be able to produce a preliminary hydraulic setting capacity brass ball valve. This is due, firstly, providing engineers calculated the required pressure loss in the circulation loop for hydraulic linkage heating system. Secondly, with the possibility of quick and efficient adjustment of the system after installation, because in practice when setting up heating systems often need additional activities to address the deviations from the project or design errors.

History of the pumps

2010-07-24T12:42:00.000-07:00

The invention pump dates back to antiquity. The first NA to suppress fires, which invented the ancient mechanic Ktesiby, was described in 1. BC. Oe. The ancient Greek scientists Heron from Alexandria in the book "Pneumatica", and then M. Vituviem at work "De Architectura". Simple wooden pumps with a through piston for lifting water from wells, probably used even earlier. Before 18. Piston pumps, compared with water engine used sparingly. In the future, due to increased water demand and the need to increase the height of its filing, especially after the steam engine, pumps gradually pushed the pumping machine. Requirements for pumps and conditions of their use became more diverse, so along with piston pumps began to create rotational, as well as various devices for feeding pressurized fluids. T., historically there have been three areas of further development: the creation of reciprocating, rotary and hydraulic devices with no moving working parts.

The rise in the development of reciprocating pumps. observed in the late 18 century. when their manufacture began to apply the metal and use the drive from the steam engine. Since the mid 19. Have been widely implemented in the production of steam direct acting piston pumps for this period include the establishment wing of pumps, a prototype of which is a piston pump with a circular cylinder is described by the French engineer A. Rammell in 1588 ("Le diverse et articiose machine"). Development of the theory of piston N. closely associated with the work of local scientists and engineers (C. Bach, G. Berg, AP Hermann, Shukhov, PK Khudyakov, I. Kukolevsky, AA Burdakov, etc.). Advances in reciprocating pumps have been widely used also in creating reciprocating compressors, hydraulic presses and other devices, but the piston pumps ranging from 20 to 30-ies. 20. Became markedly displaced from a number of areas centrifugal, rotary, etc.

Pump

2010-07-19T12:36:00.000-07:00

The pump unit (hydraulic machine, apparatus or device) to move the pressure (suction and discharge), mainly liquid drops as a result of the message to her external energy (potential and kinetic).

The main parameter of the pump

2010-07-18T12:38:00.000-07:00

The main parameter of the pump - the amount of fluid being transported in unit time, ie, carried out flow rate Q. For bolshinstvanasos critical technical parameters also include: developed pressure p or the corresponding pressure H, N, and power consumption efficiency h.

Classification of pumps USA Standard

2010-07-17T12:40:00.000-07:00

Devices for pressure transfer of liquids are divided into species and varieties on various grounds, such as the principle of action and design. Such a feature form the basis for the classification provided in the USA Standard (ASTM 17389-72). AN can also be divided into 2 groups: the pumps, machines, actuated by motors and pumps, devices that operate at the expense of other energy sources and have no moving working parts. Pump machines are lobed (centrifugal, axial, vortex), reciprocating, rotary (gear, rotatory, plate, screw, etc.). K-pump apparatuses include jet (liquid-liquid and gas-liquid), gas-lift (including airlift), a propellant (including steam and gas), hydraulic rams, magnetohydrodynamic pumps, etc.

Another way of pumps began with the invention of the so-called rotary pumps

2010-07-15T12:43:00.000-07:00

Another way of pumps began with the invention of the so-called rotary pumps, had one rotor, which were also described Rammell. Pump with eccentric rotor is the prototype of modern sliding pumps. In 1624 I. Leyrehon in the book "La recreation mathematiqae" described the rotatory rotor pump, which can be regarded as the prototype of modern gear pumps. Later came other varieties, and rotary pumps, representative of which is, for example, labyrinthine pump, already established in the 50-ies. 20. The first vortex pump, called the centrifugal self-priming, was proposed in 1920 in Germany, engineer S. Hinshaw, and then appeared and others species.

The idea of using centrifugal force, the liquid appeared in 15. Even Leonardo da Vinci and, apparently independently of it was implemented in the early 17 century. Blankano French engineer, to build a simple centrifugal pump for water, which served as a working body of the open spinning wheel. One of the first centrifugal pump with volute casing and the four-bladed impeller was proposed by French scientist J. Papen, who perfected the design previously known blowers "Hessians". In the late 19 century. When there were high-speed heat, and then electric motors, centrifugal pumps have wider application. In 1838 Russian engineer A. Sablukov established on the basis of his earlier fan built single-stage centrifugal pump, in 1846 an American engineer, Johnson proposed a multistage horizontal pumps, in 1851 a similar pump was set up in the UK patent Guinn (Guinn pump), in 1899 a Russian engineer VA Pushechnikov developed a vertical multistage pump for drilling wells up to 250 m. This pump is built in Paris at the factory Farcot (pump FARC), was intended for water supply in Moscow, had a supply of 200 m3 / h, the efficiency to 70%.

Third direction development of devices for feeding pressurized fluid combines several ways of creating pumps

2010-07-14T12:43:00.000-07:00

Prototypes of the propellants, according to the testimony of Heron, already produced in ancient Greece (the device to dislodge from the vessel of water heated air or steam). The first propellant production facilities were proposed in 1698 by British engineer T. Severi steam pumping plant. This device can be considered a prototype invented in Germany in 1871 Hullem pulse meter, which took two cameras and operate automatically.

The idea of using compressed air for water expressed in 1707, Papen and other engineers, but little has been applied much later (20.) - In monzhuse and double chamber water pump replacement for water wells (design engineer VP Savotin, USSR) . The water under the pressure of the combustion products of liquid fuel has been implemented in the UK in 1911 NL Humphrey.

Fundamentally different way of water or oil from wells with compressed air or other gas was used in gas lift, which had been proposed in the mid-19 century. And later found a practical application.

With the invention of the Montgolfier in 1796 automatically acting hydraulic ram there has been another way of development of devices for feeding pressurized fluid whose operation was based on the use of water spray from time to time created by water hammer. In the future, have been proposed various designs of hydraulic rams.

One variety of pump-sets was water-jet pump, which is like a laboratory device was proposed by British scientist D. Thompson in 1852 and served for the suction of water and air. The first design jet apparatus employed engineer Nagel in 1866 (presumably in Germany) to remove water from mines. Later established various jet pumps in the form of water-ejectors, steam-water injector, and many other fundamentals of the theory of jet pumps were laid in Tseynera G. and W. Rankin for the 2 nd half of 19. And received a significant development in the 30's. 20. Thanks to research by American engineers and O'Brien Goslina and Soviet specialists LD Berman, K. Baulina, A. Lozhkin, E. J. Sokolov, N. Singer, and others later proposed hydro-pneumatic water pump for wells (VP Sirotkin, YS Surenyants), in a design which combined jet pump airlift and. One of the directions of development of pump-sets is the creation of magnetohydrodynamic pumps. The first of these pumps at constant current proposed Golden (1907) and Hartmann (1919) and pumps with alternating current - Chubb (1915). However, they have become widely used in the USSR and abroad, only in 50-60-ies. 20., Mainly due to the success of nuclear energy. T., equipment lifting and moving initially only the water, then oil and other liquids in every period mainly corresponded to the level of development of productive forces and production relations.

- Customers of Taco company offers a wide range of pumps - Taco 006, Taco 007, Taco 008, Taco 009 and Taco 0010. Each of these species - its scope.

- Let's look at all the specific examples. Which Taco pump would be used for watering the garden?

- Summer residents are very popular among domestic circulator pumps "Taco". The capacity of 0,2 kW and 0,43 m3 / h capacity enough to ensure the garden plot and a house with water from a nearby reservoir. Household vibrating pump differs from the circulator pump and the lack of engine rotating parts, which greatly enhances its mechanical efficiency. He has a small size, it is easy to use and capable of pumping water at a distance of tens of meters.

- Which Taco pump to use if you want more water for household use?

- Automate the process of plumbing from wells or shallow (5-7 meters) wells will help small pumping stations. This station is mounted on the same basis and a small pump, at 22-25 liters, a membrane tank (accumulator). I must say that the weight represented in the assortment MPO Wiring "pumping stations is around 12-22 kg, that is, it may well carry one person.

Individual heating systems with Tankless water heater Takagi JR

2010-05-13T14:53:00.000-07:00

Individual heating has long been common practice in Europe. Such popularity of individual heating systems is well founded. The main reason is that this method of heating rooms at least 2 times more efficient than the system of collective public services. Wall mounted gas tankless water heaters allow consumers themselves to regulate the temperature in the apartments, turn off the heat for prolonged departure or during the summer. This reduces gas consumption and save money.

Now individual heating actively developing in Japan. It's no secret that our country is central heating in some regions no longer operates. The introduction of individual heaters can solve this problem. This practice already exists and is constantly expanding. Here are some examples.

As the benefits of domestic tankless water heaters in the Voronezh region has been able to see about three thousand families. It is so much home "mini-tankless water heater" is set in the apartments of Voronezh for the 2002-2004 year. The program continues. About his participation in the implementation of high-efficiency innovation have 27 districts. In this case Semiluki and Talovskoye areas expected to be installed over a thousand domestic tankless water heaters, Takagi Tankless Water Heaters - about 700, and Stiebel Eltron Tankless Water Heaters - over 500. The total number of people wishing to transfer their apartments to individual heating close to six thousand. According to experts, the introduction of individual heating circuits can also make a much cheaper housing, because there is no need for expensive heating systems and heating units, as well as help to reduce tariffs.

Small city of Ogahawa region move to individual radiant heating. Thus, in Solonyanskom area of more than 70% of apartment buildings have already installed in their apartments needed gas equipment. Head of Housing Governor noted that this process is not under pressure from provincial authorities, as dictated by the need and desire of the population.

The effect of the introduction of the above systems is directly dependent on the quality of tankless water heater equipment. The most technologically advanced and reliable wall-mounted gas tankless water heaters developed by German company Takagi JR. Special attention should be a new series (Takagi, Stiebel Eltron).

Radiant heating system with a lower filling.

2010-05-04T15:06:00.000-07:00

The Radiant heating system with a lower bottling among the townspeople not uncommon. And it is not in vain, because, along with other Radiant heating systems it is distinguished by a number of characteristics that enable consumers to make his choice in her favor.

Let us consider the main advantages and disadvantages of this system, to see how beneficial and necessary to install it in urban apartments.

First of all, you need to pay attention to its structural features. Pipe systems are installed on the floor, so you will not have much thinking as they hide. Pipes can be something close. The main technological advantages should be made good heat transfer. This is all the same design features, that is due to the fact that the pipes are installed at the bottom, they heated floor and not a ceiling.

However, despite all these advantages Radiant heating holiday home with a lower bottling is far from ideal, as also has its drawbacks. Foremost among them is the resistance of the system. This means that for the normal functioning you have to acquire a very powerful pump, which would entail extra costs. Moreover, your costs will also involve the acquisition of materials for the installation of the heating system.

Also, with the lower heating bottling provides additional installation of special control valves and vent. And the vent must be exactly as much as radiators will be connected to the heating system.

Pumps and Pump Equipment

2010-04-28T10:51:00.000-07:00

The most widespread and familiar pumps are pumping, intended for the abstraction of pure water mostly from wells or boreholes, rarely - from a lake or river. Terms of Use define the structure, whereby the pumping pumps are classified into the surface, submerged and submersible borehole.

PEX Tubing, in general, better wall up against the wall. Forever. Now, success is guaranteed: a drop of a drop of water from the "street" PVC will accumulate in the ceiling between floors and one day break through to the downstairs neighbors. In the best case - in the form of swollen plaster in the bathroom. Drench all the floors (as is done in New York valiant firefighters while extinguishing the fire) you are unlikely to succeed, but the local popularity you will undoubtedly get anywhere.

Varieties of Radiant Heating

2010-04-19T13:02:00.000-07:00

The popularity of these heating systems is constantly growing. For example, in Sweden 90% of newly built houses equipped with a heating system with Radiant Heating, in Finland - 50%.

There are two main types of warm floor: water and electric. Air floors, because of their exotic and expensive, will not be discussed. And water, and a PEX tubing warm floor one thing in common - a low temperature heater (the temperature of the floor surface rarely exceeds 30-32 ° C), very large area. Usually the whole floor area radiates heat.

However, if the room is planned to install furniture or equipment that will not move, then the warm floor beneath them is not done. The design of such floors is as follows. First is dirt or concrete base, then - a layer of warmth and waterproofing. Insulation laid on top of concrete screed with fuel elements: pipes of hot water or electric radiant heating. You may ask: "Why do you complicate things, when you can just hang on the walls of the battery?". Answers - for comfort.

The author has personally experienced something almost heavenly bliss, which provides such a system. Being in the house where the only heating was warm floors, I was surprised that the air temperature in the room did not exceed 18-19 ° C. In the yard - minus 24 ° C, and a general sense - all the comforts. The house shed a soft, pleasant warmth. Arrogant cat was not to banish from the tiled floor, where the animal warmed after a walk down the street.

The explanation can be found on the plot of temperature distribution depending on the height of the room. Everyone knows that under the traditional heating system (radiators and convectors) heated air rises and cools down, fall down. Therefore, the ceiling is hot, at the floor level is cool, but at the height of the head temperature is somewhere around 22-24 ° C.

A different picture emerges in the room if the heat source - the floor. There is also the warm air rises to the top. But there are significant differences: the temperature of batteries or convectors high - +70 ° C, with the temperature gradient is large enough, loud and the air velocity in the resulting convective flow. Inevitably drafts, because the size of radiators or convectors are limited, and the air is heated, rises strongly over the radiator and goes elsewhere. Thus, in the room formed by a constant and steady current of air, which moves together with the dust, pet hair and other household pollution. You have not asked ourselves, where so much dust in the closet?

Repair your plumbing valve

2010-04-16T12:40:00.000-07:00

Because is plumbing valve normally open, then in order to avoid leakage, seal must be sufficiently tightly packed. If you found a leak, tighten the compression nut slightly to seal the stuffing. If the nut is wrapped all the way, and compression gland packing does not work, have to add padding. You do not need to override the water in the pipe before the valve. It is only to observe certain precautions.

Tighten the flywheel until it stops. Open the valve and check valve closure. Holding the flywheel in place, fully unscrew the cap nut. Remove the flywheel, leaving a fixed stock. Remove the cap nut and remove the sleeve seal. In the gap between the shell and put the rod seal. Entwine their stock and rammed a screwdriver. Do not forget that the gap still has to fit sleeve, so that the nut could grab a few threads of threads Corps.

Analyzing the valve, remember that you can not remove the sleeve, if water is not blocked, otherwise the water pressure in the valve can squeeze seal, and the water hit through the gap.

When fully twisted rod water continues to flow through the valve (the valve does not hold water). Several times the open-close valve. Caught between a saddle and pad particles must leave the water. If the valve is still holding back the water will have to dismantle. To do this, close the valve to enter the apartment, or the valve on the risers, if the breakdown in it.

Decomposing the iron gate to help heat the head with a blowtorch or gas burner. If your apartment has cast iron valves, stock up well in advance of a new head shell assembly with a rod, because after several years of operation of a steel rod is usually fused, rusting, cast-iron head case. A durable cast iron valves with brass rods.

The valve has a "floating" landing on the rod with ball joint. The defect can be partial destruction of the wall reducing mechanism valve Such failure requires replacement of the valve stem.

Steel radiators KERMI

2010-04-08T09:56:00.000-07:00

Steel radiators KERMI

Company KERMI (Germany) for 40 years, holds a leading position in Europe for the production of heating appliances. The most popular steel radiators, which accounted for 95% of all sold in Europe heaters.

Steel panel radiators have special properties not possessed by other types:

* They are designed to work in modern energy-saving automated closed heating systems;
* Made of cold rolled steel of thickness 1.25 mm;
* Have one-, two-and three-row design with convection fins and without them;
* The range of nominal power and constructive solutions allow you to set radiators in rooms with different desired temperature at any desired location.

Found that the most comfortable warmth we receive when using the spectrum at low temperatures in the heating systems. Become the norm coolant temperature 60-75 ° C, because at low temperatures is greatly simplified system management and administration, saving fuel, electricity, saving costs. In contrast, steel radiators, such as autopsy, where at lower water temperatures in the supply pipeline should significantly increase the size of the radiator, and the coil under these conditions generally do not work, high-quality steel radiators KERMI feeling well. It is also important that the radiators can be installed in the system, assembled from steel, copper, plastic and metal pipes, in single-and double-tube closed system with diaphragm expansion tank.

Why steel radiators are most effective? It would seem, cast iron radiator, although cumbersome, but warms reliable. In fact, to cast iron radiators give as much heat as steel and, through it must pass seven times more water and that its temperature for the cast-iron radiator should be above about 20 ° C. This, in turn, will require more consumption of electricity, gas or diesel fuel.

Steel radiators are good its energy efficiency, especially for the cottages. For example, one heating system in a private house, designed for heating of cast iron radiators, replacing them will be able to heat the steel is two to three more homes is another significant paper savings.

Energy efficiency trends in the development of boilers

Modernization of equipment, especially heating, aims to also take into account the public interest. Questions of cost and resource management are increasingly addressed at various levels. Developed various programs for "sustainable energy". They emphasize the state as a whole and each person in particular on the benefits of the introduction of more sophisticated equipment. Especially in the part of which is aimed at reducing energy consumption and environmental pollution. One way of moving towards a peaceful coexistence with nature is determined by the formation of information-oriented lifestyles.

In order for energy efficiency equipment shall be considered not only as a way to save money, but as a method of careful and rational use of resources at the state level are special projects. These documents are developed, on the one hand, to encourage manufacturers to use advanced technologies in energy consumption, on the other - raise awareness among consumers. In Europe, the operational directive 92/42/EES on demand efficiency for new hot-water boilers using liquid or gaseous fuels. According to the document, for they introduce a special mark showing the efficiency of the device match accepted standards. Equipment with the highest estimate of the effectiveness marked by four stars.

In the matter of saving as a separate item stands out the possibility of using alternative sources of energy. Many countries are actively using wind and sun, even when individual building. For example, at an exhibition contest "Solar Decathlon in Washington, was among the other submitted to the house, provide energy not only themselves, but also a small electric car. Many manufacturers of heating equipment take into account such a high popularity of alternative resources for modernization and provide an opportunity to use the boiler with a solar collector.

Environmental contamination is not equally urgent than energy. Emissions of nitrogen oxide formed during combustion of gas, toxic. In connection with this concern of various public organizations influenced the adoption of more stringent standards on emissions into the atmosphere. This in turn boosts the production to use technologies that minimize emissions of toxic components. Products in accordance with the volume of unwanted emissions are assigned to classes of security.

The modern experience of designing new boilers Specificity of heating equipment is the need for its installation and periodic maintenance. Therefore, serious producers in the process of developing a new product take into account both the needs of customers and specialists suppliers and assembly companies. In this connection, when designing a manufacturer tries to provide for improvements that would have made it a product suitable for professional work.

Primarily these changes relate to design features. Using the boiler starts with the installation, the simplicity of which is an important advantage in the eyes of a specialist. For example, all new line of boilers ARISTON built on a single platform that allows much easier installation and maintenance. There is also a new range of hydraulic connections to the wall and the chimney connection. In the interest of service technicians in the design of such methods are used placement of all components of the boiler (access from the front for most of them), which allow for viewing with minimal effort and time. As is known, except for the audit of the burner and control of flue gas should be a periodic recharge of the coolant. In boilers of new generation provides a solenoid valve recharge and built-in semi-automatic recharge, which makes this procedure easy and safe.

The issue of reliability in the design of giving one of the utmost importance. There was a major part in the process workers are assembling and service organizations, because they, when confronted in his work with the most urgent problems, suggest the main causes of breakdowns. Experts carrying out the installation, are interested in the longevity of the equipment not less than the users themselves. After all, frequent crashes of the recommended equipment they affect not only the credibility of the manufacturer, but also the reputation of the installer. According to Gabriele Montesi, "taking into account the climatic and other features of Russia can say: if the boiler works well here, so they will easily run everywhere. Therefore, any comments and suggestions of Russian specialists considered a priority, especially since it is a very qualified people. " Focusing on the received valuable information on the production technology was promptly carried correction (for example, added new protections against frosting smoke removal systems).

However, if it fails in the boiler, the main task specialist - correctly install its cause. However, this part of the renovation would address himself boiler, if it is equipped with modern diagnostic system. For example, the LCD display reflected an error code with an explanation, and in Russian. The system self-test also allows you to save the latest information about the fault required for the analysis of the equipment.

System GPRS, through which the user can control the boiler at a distance, makes it possible to establish a permanent electronic link with the service center. Such a system (E @ SY) has already been introduced in several Russian regions, in particular, in the Belgorod region.

As a result, upgrading the heating equipment has set itself targets not only the market, but also public. The effect of the development and introduction of new methods in the boilers to customers is reflected in increased comfort and the possibility of an individual approach to heating their homes, as well as savings in energy. Professionals distinguish features that are important to install and maintain. And for society, these changes - small but nevertheless a step towards environmental protection and energy-efficient use of resource potential.

PEX Heat Transfer Plates

2010-03-18T07:52:00.000-07:00

PEX heat transfer plates are most commonly used in ‘staple up systems’. Through this system the floor is heated by introduction of heating plates under the flooring. In this process aluminum type of material is wrapped around the heating pipe. In the very beginning heat transfer plates were expanded to resolve the two important issues formerly linked with radiant heated floors, noise and cold spots. These issues were most commonly seen at the time of installations.

Stamped Heat Transfer Plates

Extruded Heat Transfer Plates

The PEX Heat Transfer Plates are made up of a fine aluminum and the most commonly used methods in the manufacturing of these plates are either stamping or extrusion techniques. This plate is very important in improving the performance of the Radiant Heating system by distributing the heat from the PEX tubing in to the floor above. In order to reduce the heating cost these plates also call for a lower water supply at high temperature to reduce the heat.

The best features of PEX heat transfer plates are their breadth and the flat surface and these are very beneficial in distributing the heat. There are two different types of heat transfer plates that are available in the market. They are the thicker heat transfer plates and the thinner heat transfer plates. Thicker Heat Transfer plates are usually planned for under subfloor installation.

The heat transfer plates are commonly known for its three major functions.

They are:

1.Heat transfer plates are useful in carrying away the heat from the tubing and distribute it through the floor joist and along the bottom.
2.These plates are well supported by plastic heat exchanger tubing.
3.The heat transfer plates significantly lessen the heat loss in the down track.

There is some dissimilarity in the views about the thickness and the quantity of the aluminum and also in the necessity of aluminum in the PEX heat transfer plates.

Types Of Taco Pressure Reducing Valves

2010-03-16T12:01:00.000-07:00

The range of Taco pressure reducing valves is geared to feed water inside a system as soon as the pressure within the system goes below the original pressure setting within the Taco valve. There are three versions of the Taco pressure reducing namely the Taco 329, the Taco 334 as well as Taco 3350.

Different Styles

As far as the Taco pressure reducing valves are concerned, there are three different styles. These include the sweat versions of the Taco pressure reducing, which comprise cast iron body material and the threaded versions of the Taco pressure reducing comprising bronze as well as cast iron body materials. The Taco 329, the Taco 334 as well as Taco 3350 fall within these three styles and designs.

Sweat Style

The sweat style of the Taco pressure reducing valves are used to feed water into the system automatically as soon as the pressure falls below the original valve pressure setting. The presence of dual control type models use a combination of pressure relief type valve in-line as well as boiler feed. The adjustable pressure range in the Taco pressure reducing valves is between 10 and 25 psi and the presence of in-built checks system emptying in cases where the incoming pressure is below the configuration. The fill rates are very fast and there is also a lever with fast filling mechanism and exclusive lockable mechanism. The maximum pressure for these Taco pressure reducing valves is around 100 psi while the maximum temperature range is around 212 degree Fahrenheit.
