Repair small bamboo toggle blades are available, and if the motor can run properly, that is to start winding damage, should replace or repair the startup winding of the same capacity;If the motor is jammed, is caused by the motor and pump head of the fault, such as bearing damage, such as impeller jammed.


3, the motor can run, but speed is slow, chassis overheating, burning taste.

May be a motor short-circuit, should open motor to view of the seriousness of the injury.


4, large noise vibration during operation.

Most is bearing damage or bearing and chassis mismatch, need to open motor to check, and if the bearing damage should be replaced;If bearing "outside running round", is used for the mating surface of the pump housing can flower;If bearing "circle", but to the motor shaft wear and tear parts adopt flower processing, serious wear and tear, and adopt the method of surfacing welding before turning to repair.
