摘要：During the normal operation of an ultra-supercritical 660MW steam turbine in a power plant, the temperature of low-pressure shaft seal steam inlet gradually increases, and the vibration of steam turbine bearing suddenly increases, leading to the steam turbine shutdown. The diagnosis and troubleshooting of major vibration faults of steam turbine bearing are carried out, and the causes of faults are accurately analysed through collecting field data, checking maintenance records and disassembling inspection of relevant equipment. Taking corresponding effective measures to eliminate the potential equipment safety hazard.
