摘要
某台PG5361P燃气轮机大修后试机过程中发生轴瓦乌金烧损,推力盘和轴颈磨损,叶片、气封和油封磨损等事故。结合检修和运行数据,对故障原因进行分析,指出检修不当所导致的推力轴承缺陷是故障主要原因,监测不力、采取措施不及时是事故次要原因。运行中应加强和重视对参数波动现象的监测。
Faults such as bearing babbitt failure,journal wearout,blade and seal damage occurred in a PG5361 P gas turbine during starting up process after the overhaul of the unit. Fault reason was analyzed on the base of the repair and operation data. It is pointed that bearing damage caused by unreasonable repair techniques is the main reason of the fault,unreasonable monitoring of the unit and the delayed decision of break down is the secondary reason. It is important to monitor parameter unsteady change during normal operation.
