Cause of Overload Current of Submersible Pump Motor and Its High Temperature and Its Solution

Submersible pump current is too large The main reason for overload or overtemperature:
(1) operating voltage is too low or too high; check the power supply voltage, adjust the transmission voltage.
(2) There are static and dynamic components within the pump or contact with the impeller seal ring friction; to determine the location of friction parts to eliminate failure.
(3) low head, large flow caused by motor power and pump characteristics do not match; adjust the valve to reduce the flow, so that the motor power and pump to match.
(4) pumping density or high viscosity; check the water quality changes, change the working conditions of the pump
(5) bearing damage; replace the motor at both ends of the bearing
