Firstly. Analysis of the motor overload situation. Use a clamp meter to measure the normal current of the motor. If the current of the motor is large and small, it may be that the hydraulic pressure has been increased. The current is relatively large, and the current of the hydraulic system is too high when it does not start to run, which means that there is a problem with the motor.
Secondly. Check whether the bearing of the motor of the hydraulic system is stuck and the rotor is swept, because when such a fault occurs, the operating technician can usually hear the sound.
Finally. The voltage fluctuation of the external power grid becomes larger, we can test with a multimeter. It may be caused by the large resistance of the hydraulic pump, the mismatch between the motor and the pump, the insulation drop of the motor, and the reassembly after disassembly.
