The deep well submersible pump is a water lifting machine that is directly connected to the motor and the water pump. It has the advantages of simple structure, high efficiency, low noise, safe and reliable operation, convenient installation and maintenance. It is suitable for extraction from deep water wells, hot water wells and oceans. It can also be used for rivers, reservoirs, canals, etc. It is mainly used for irrigation of farmland and human and animal water in plateau mountainous areas. It can also be used for cities, factories, railways, mines and construction sites. Use for drainage.
Many users do not know how to determine the lift of the deep well pump when selecting the deep well submersible pump. In fact, the lift generated by the deep well pump is determined. In addition to the required pressure value to output the water from the outlet, the pressure loss inside the pump should be overcome. It includes the pressure loss in the pump tube and the pressure loss caused by the increase of water flow in the pump, that is, the dynamic water level of the well.
The head of the deep well pump can be estimated initially according to the use of the deep well pump in different occasions:
1. How to determine the actual required lift of the pump by supplying the pump to the water tower
H=H1 +H2 +Ho
The head that the H-pump actually needs (m)
H2——The downhole lift, that is, the height of the moving water level in the well to the ground (m)
H2-water tower height (m)
Ho——Loss lift of the piping system (m)
2. How to determine the actual required lift of the pump by supplying the lift of the deep well pump to the surface pool
H=H1+ Ho
3. How to determine the actual required lift of the pump by supplying the pump to the pressure system
H=H1+ H3 +Ho
H3 in the formula - water pressure at the water outlet (m)
The specification of the pump is determined according to the initially determined flow rate and head value. The pump of the appropriate specification can be selected from the characteristic curve of the deep well submersible pump, or the pump with the specified flow rate and the specified head can be selected according to the required flow rate and head to make the deep well. The pump can run near the high efficiency point of the Zui, thus improving the water supply efficiency of the deep well pump and improving the economics of the water supply unit.
The correct choice of the head of the deep well submersible pump is one of the methods for the service life of the submersible pump. The lift selection is too low to reach the rated flow rate or even the water; the submersible pump's lift selection is too high, the submersible pump motor will over-current and overload, and even burn the motor. Reasonable choice of pump head is the scientific choice for the correct use of pumps and energy saving.
