First of all, the manufacturer’s solution to the problem of equipment components is to check whether the power socket, power cord, etc. are broken or there is no oxygen falling off. If these problems occur, they must be resolved in time, otherwise the power supply can be used and test machine work can be performed;
The second is the problem that the motor does not rotate after the vertical mill is powered on. At this time, turn the wheel lightly to observe the master's rotation. If it rotates, it means that one of the vertical mill's starting capacitors has failed;
Once again, the vertical mill rotates after applying pressure and will emit a faint current noise, indicating that the starting capacitor is leaking slightly. If the current is loud and the motor cannot be started, it means that the starting capacitor is short-circuited;
