Thrust pad damage of a 16 MW Generator
Thrust pad damage of a 16 MW Generator
(OP)
Dear All, We are having a 16 MW 11 kV Generator. Recently thrust pad of machine got damaged. Mechanical team is fearing that it may be due to improper magnetic center of Generator. Please guide me on following:
1. If thrust pad can get damage due to improper magnetic center?
2. How to test that magnetic center is out
3. How to correct the magnetic center.

In horizontal generators, the thrust pads are only for momentary contacts and momentary loads. Constant contact will damage the thrust pads. Constant contact can happen due to improper assembly, improper magnetic centering etc.
In vertical generators, the thrust pads are designed for constant thrust load against a thin oil film. If oil supply is lost, the thrust bearings will fail within seconds due to direct metal to metal contact.

I also agree with edison, lots more info would be helpful beyond "thrust bearing got damaged"
unfortunately op hasn't logged on in about a month...
