Modern water pumps are a family of diverse design and principle of operation of devices. The function is to move the convertible jet pumps, as well as creating pressure of various substances. Substances may not only in liquid or gaseous state, but also presented as a mixture of solid particles and colloidal masses. Because of this, the scope of the pumps is very diverse. In particular, the pumps can handle all types of piping from main to transport across continents oil and natural gas, and to the utilities, which are responsible for water supply and disposal of waste.
When choosing a pump should be guided by the following parameters – performance and pressure. Capacity (in other words flow) indicates how many liters per minute (cubic meters per hour) can pump the pump. Head – a characteristic that determines the height at which the pump can deliver water.
The pumps are classified on the surface, submersible, sewage, drainage and circulation.
jet pumps. Their difference lies in the fact that they are out of the water source, water abstraction itself is carried out by suction. jet pumps are divided into the vortex and centrifugal.
Vortex pumps are Electropump station. They are designed for pumping water, as well as neutral and chemically active fluids. The application range of these pumps is quite wide, fire extinguishing systems, domestic water supply, ventilation, heating, chemical treatment and much more.
At the surface there is the possibility of pumps used in confined spaces due to their small weight and dimensions.
Self-priming jet pump are mainly used for pumping clean water from wells, shallow wells, springs, as well as the development of pits and other purposes.
Surface jet pump can be fitted with both external and internal ejector, so that the pump can operate in a system in which bubbles are formed, or air pockets. jet pumps are usually presented in the form of water pumping stations semiautomatic. In addition to the pump in the pumping station consists of accumulator and control system.
Submersible pumps are used where the surface can not be applied, in particular, with great depth of the source. These pumps are immersed directly into the water. To ensure normal operation of a submersible pump, the depth should be at least a meter.
In the group of distinguished well submersible pumps, and jet pumps.
Pit pumps are less sensitive to other particles, in contrast to the well. They can work in partial immersion, because the pump motor is cooled by the pumped water, which minimizes the possibility of overheating.
Submersible pumps are used to supply water containing mechanical impurities.
Drainage pumps are used for pumping contaminated water, which contains a small amount of impurities, for example, from the cellars, wells, cellars, tanks, etc. The advantage of such nasosv is their compactness, there is no need for maintenance and long life.
Sewage pumps are designed for pumping contaminated fluids, which are analogous to the drain, but it pumps the larger particles.
Shallow well jet pumps are used for water jet pump systems, hot water and heating, as well as underfloor heating systems. The jet pump is a key element in the heating system with forced circulation.
