What is the defection of water pump
Reversing the pump will cause the motor to increase current, small water or no water
Anti water hammer phenomenon that is usually said, it is in the high pressure water pump suddenly stops working, the height would hit back phenomenon called defectionThis situation generally occurs in the water pump outlet does not install a check valve, the valve with a check valve has a sound, but the check valve can be a good protection of water pump
The structure of the water pump and water pump water.Because: when the pump head exceeds the rated head, pump current will increase, the water discharged from the pump impeller, back to the inlet of water from between the impeller and the casing exceeds the rated value, if it is a high lift pump, clearance between the impeller and the pump shell is very small, the current increases with increasing lift, current exceeds the rated value too soon many motor will be burned.
Water pump installation of a one-way valve on it.
