Man has long begun to create special devices for lifting water to a height. One of the first mechanisms for the intake and subsequent supply of water was a noria - a wooden wheel with scoops, partially submerged in the river and set in motion by the flow of water. But in the modern world, such equipment as pumping stations has appeared, which provide water supply not only for buildings and structures, but also for adjacent territories and lands.
Content
The main applications of pumping stations (hereinafter referred to as pumps):
Water is supplied from a source to water treatment facilities, from clean water tanks of water treatment facilities for household, drinking and fire fighting purposes, for the production needs of industrial enterprises located in cities.
Pumping of domestic and surface (rain, melt, irrigation, washing) wastewater, their supply to treatment facilities.
Ensuring the circulation of the coolant; in drainage systems of cities and industrial enterprises. Groundwater pumping.
Water supply for land irrigation.
Providing water for hardening mortars and concrete, and transporting the resulting mixtures to the place of use, for moistening concrete, watering the territory, washing construction equipment, pumping groundwater during the development of pits and trenches.
Water is supplied from a source to industrial, domestic and drinking and fire-fighting water supply systems, ensuring water circulation in the water cooling systems of turbine condensers, transporting water at various stages of its preparation for use as feed water for steam boilers, supplying feed water to steam boilers and for other purposes.
Distribution of water from the source to the systems of industrial, domestic and drinking and fire-fighting water supply, ensuring the circulation of water in the circulating water cooling systems of technological units, raw materials and industrial products, supplying water for cleaning process gases, supplying water for the preparation of chemical reagents and ensuring the transportation of the reagents themselves to place of use, as well as for other needs.
Water is supplied from a source to industrial, domestic and drinking and fire-fighting water supply systems, to ensure ore dressing processes, to prepare reagent solutions, to cool and lubricate pump seals, to ensure the transportation of tailings to waste storage facilities, to pump out mine, quarry and dump water and for other needs.
Water is supplied from a source to industrial, domestic, drinking and fire-fighting water supply systems, for water circulation in circulating water cooling systems for process equipment and rolled products, for water circulation in circulating systems for water treatment and cooling of process gases of blast furnaces, oxygen converters, electric steel-smelting furnaces and other metallurgical units, for the preparation of solutions in which the metal surface of the rolled metal is processed, and for the subsequent washing of this rolled product, as well as for other purposes.
All pumping stations (hereinafter referred to as pumps) are divided into two fairly large categories: dynamic and positive displacement pumps.
Dynamic units according to the forces of influence on the water that moves in the sealed chamber of the pump are divided into the following categories:
A vane pump is a mechanism that transfers all the energy through the vanes, constantly rotating rapidly, which leads to the appearance of the direction of the liquid and pressure in the machine.
Vane pumps are:
centrifugal unit - this is the same vane pump, inside which the liquid runs over a wheel with blades from the center to the periphery.
The latest centrifugal machines are categorized according to some criteria:
The above list of machines with centrifugal action is not complete, since they can still be divided according to other criteria.
axle unit is a mechanism that distributes all of its fluid along the axis of the working screw. It consists of a fitted sleeve and paddles attached to it, deformed so that they give direction to the movement of water. When this type of screw begins to rotate, the fluid with a certain force and pressure begins to be captured by the blades and pushed out in a certain direction. Such pumps are usually used in those jobs that require the use of a small pressure of the pushed out water.
Diagonal pump according to the principle of operation, it is similar to both centrifugal and axial units. The liquid moves with the help of centrifugal force and enters the pump in the direction of the impeller rotation axis, and exits at a certain angle to the axis of the machine itself.
Friction pumps are dynamic, in which the fluid moves through the force of friction.
These pumps include screw and vortex pumps.
The screw mechanism distributes water by moving it through the screw screw in the direction of its own axis.
The vortex unit transfers the fluid along the periphery of the impeller in a tangential direction.
From the name of the pump it is clear that the electromagnetic unit carries out the liquid moves with the help of electromagnetic forces.
Volumetric aggregates function by means of a mechanism for pushing a liquid out by a solid body.
Types of pumping stations:
Volumetric pumps are designed to reproduce a huge water pressure, reaching up to 100 meters with a small amount of liquid used. Such units have high power and self-priming function.
Reciprocating rotary pump is a reciprocating mechanism with reciprocating movement of the leading link. They are toothed and screw.
The rotary-translational pump is a mechanism based on a rotor with reciprocating and rotational movement of the working units and parts of the unit. Such pumping stations include piston and diaphragm pumps.
The principle of operation and operation is a powerful mechanical rotation using the rotor of the pumping station.
In order to qualitatively provide your home, auxiliary facilities and land with water supply, you must choose the right pumping station. To successfully complete such a difficult task, there are criteria for choosing a pumping station:
Based on the above selection criteria, the purchase of a pumping station will be much more productive and profitable.
