A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy or other external energy of the prime mover to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid-base liquids, emulsions, suspoemulsions and liquid metals.
If the water pump has relatively minor faults, remember not to let it work. If the packing of the water pump shaft is worn out, it should be added in time. If the water pump continues to be used, air leakage will occur. The direct effect of this is that the energy consumption of the motor will increase, which will damage the impeller.
