摘　　要：FMEA(失效模式与影响分析)是一种可靠性分析的重要方法。FMEA可用来识别潜在的故障模式,确定其影响。应用FMEA方法,分析了调节汽门控制回路各组成部分的失效模式及其影响,得到了相关FMEA表。通过结合FMEA方法的故障诊断,成功定位了故障源,并根据其失效模式采取了相应的处理措施,最终成功消除了调门摆动故障。FMEA（Failure Mode and Effects Analysis） is an important method for reliability analysis.FMEA can be used to identify potential failure modes and determine their impacts.Through the application of FMEA,the failure modes of the various components in governor valve control circuit and their impacts is analyzed,then the related FMEA forms are obtained.Through the comparative analysis of diagnostic results and FMEA forms,the fault source is successfully located,and the treatment measures is devoloped and taken to successfully eliminate the governor valve wobble failure.
