摘要
论述活动部件引起振动的机理和诊断方法,详细介绍一台200 MW机组振动故障的诊断。通过对试验数据的分析,判断出低压转子中心孔的堵头落入联轴器内孔,据此进行了针对性的检查,证实了这种判断的正确性。
This paper describes the mechanism and diagnosis method of vibration of steam turbine arising from the moving parts on rotor and details the diagnosis of vibration fault of one 200 MW steam turbine. Through the analysis of testing data, it was thought that the loose caulking block of center bore of low pressure rotor fell into the internal opening of coupling, and the following inspection proved the correctness of judgement.
