In view of the above problems, the vertical roller mill needs to be maintained or repaired. If there is no professional instrument, the capacitor can be removed first, and then the two leads are inserted into the zero and live wire jacks of the mains to charge the capacitor. When the charging is completed, the two leads Short-circuit discharge, and then check whether the capacitor is available. The general method is: discharge sparks and a very loud "pop" sound, then the capacitor is available. If the spark and noise are weak, the capacitor needs to be replaced.As for the faults and corresponding solutions in the production of vertical roller mill components, the above summary is relatively clear. In the actual work process, only the maintenance of the equipment can ensure the working status of the equipment.
