The problems of energy supply systems and sanitation

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 The basic parameters and dimensions" is outdated in terms of basic parameters and dimensions for the Taco 007 boreholes, where the best foreign models outperform the multiple indicators.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

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, 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.

Grundfos Pumps

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.
