摘要
某电站汽轮机振动出现异常波动。根据机组正常运行数据、启停机振动数据分析,振动原因为联轴器螺栓松动。总结出不同支承结构联轴器螺栓松动故障特征,为类似故障诊断分析提供参考。
Abnormal fluctuations in the vibration of a steam turbine in a power station.According to the analysis of the normal operation data of the unit and the vibration data of starting and stopping,the cause of the vibration is the loose coupling bolt.Summarize the fault characteristics of coupling bolt loosening of different supporting structures,and provide reference for similar fault diagnosis and analysis.
