How to deal with the large vibration of the C-row motor?

Method for handling large faults in C-row motor vibration:

Processing passed:

First, the vibration before the working conditions: Load: 300Mw, DEB; furnace: ABCD row, BCD grinding; C row motor vibration.

Second, the event and process:

1. Reduce the load to 240Mw, stop the maintenance and replace the motor;

2. After replacing the spare motor, the center of the motor shaft is 0.95mm high, which is difficult to adjust;

3. After adjustment, put the load up to 300Mw;

3, C row motor coil temperature rises faster (up to 112 degrees); check ventilation is not smooth;

4. Stop the C row and replace the processed original motor;

5, put into operation C row, still not quite normal;

6. After repeated processing, the test conversion is normal.

Third, the cause analysis: C row motor vibration cause: motor fan end bearing wear.

Fourth, preventive measures;

1. Improve the quality of maintenance and strengthen the technical training of electrical maintenance personnel.

2. Strengthen regular inspection and maintenance.

3. Strengthen the quality of the inspection.
