What is the current of the pump when it is started?
When the motor starts, the rotor changes from a prohibited state to a rotating state, requiring a great torque, and the current must increase. When the pump starts, because there is water, it is started with load, and the current will be greater.

Just started when the pump current is 2-3 times the rated current is normal, so, the power is greater than the pump motor, many small factories in order to survive, the small motor will cut corners, produces motor burning phenomenon, and pump failure caused by load current is increased, and the pump flow rate exceeds the rated flow is a super current. General large water pump is the first to start the water pump, and then open the outlet valve, is to solve the pump just started when the ultra current problems.After excluding pump fault flowmeter check flow is beyond the rated flow, the excess can pumpslittle off flow control valve to reduce the current problems above are not dismantle the motor current of the motor itself over to see how to judge whether the motor has fault.
