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 The basic parameters and dimensions" is outdated in terms of basic parameters and dimensions for the Taco 007 boreholes, where the best foreign models outperform the multiple indicators.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

History of the pumps

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.

Classification of pumps USA Standard

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

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

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.

Pumps and Pump Equipment

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.

Circulation pumps provide constant circulation of water in the heating system.

Drainage pumps are distinguished by its ability to pump contaminated water - with an admixture of sand, silt, wood chips and other debris. They are necessary to eliminate the effects of floods and flooding, any accidents, for pumping polluted water from cellars, basements, ditches and trenches, to work in the drainage systems - are inevitable if the house is in a depression.

Fecal pumps are designed for the most contaminated and aggressive media, and designed for continuous use in sewer systems, simple and reliable. They are supplied with special cutting mechanisms capable of grinding solid fractions.

Naturally, the tougher operating conditions, the greater the reliability required from the Taco 007 pump, so it is more expensive and harder to the device. Some pumps are supplied with sensors and control systems. And most importantly, pumps are distinguished by performance and created pressure, on required for this power and mind power. Most often complicated and expensive pump can replace a simple model, but that's not always.
