摘　　要：某电厂8号机600 MW汽轮发电机在A级检修冲车过程中因稳定轴瓦振动异常被迫打闸停机,对励磁机稳定轴组合晃度重新调整后,机组正常运行时励磁机稳定轴瓦轴系振动相对稳定,但启停机过程中振动异常,机组运行存在安全隐患。针对该缺陷进行分析,并提出相关的检修优化方案,为相同机组励磁机的稳定轴瓦调整提供依据,确保机组安全、可靠运行。The 600 MW steam turbine generator of No.8 unit of a power plant was forced to shut down due to abnormal vibration of stabilized bearing shell during class A overhaul and wash.The combination sloshing of stabilized bearingof exciter was readjusted and treated.After treatment,the vibration of stabilized bearing shell shafting of exciter was relatively stable during normal operation of the unit,but during startup and shutdown,there were abnormal vibration and potential safety hazards in operation of the unit.In this paper,the defects are analyzed,and relevant maintenance optimization schemes are put forward based on experience,which provides basis for stable bearing shell adjustment of exciter of the same unit and ensures safe and reliable operation of the unit.
