韶关发电厂8号机组大修后振动故障诊断及其处理

Vibration fault diagnosis and treatment for overhauled Unit 8 in Shaoguan Power Plant

对韶关发电厂8号机大修后启动过程中轴承振动及带负荷后出现的轴承振动进行监测、诊断,找出轴承振动故障原因,并制定相应对策,解决了发电机转子临界转速下轴承振动大的问题以及机组带负荷后2号、3号轴承出现的半速涡动问题,大大提高了机组运行的安全性。

By monitoring and diagnosing the bearing vibration during startup and onload operation of overhauled Unit 8 in Shaoguan Power Plant,the cause of the vibration is clarified and corresponding countermeasures formulated,thus eliminating unacceptable bearing vibration at generator rotor whirling speed and the halfspeed vortex on No2 and No3 bearings during onload operation of the unit,and greatly enhancing the safety of the unit.
