摘　　要：通过一起给水泵汽轮机振动异常的分析,提出了该汽轮机振动的主要原因为排汽管膨胀受限及缸体疏水不畅,提出了相应的处理方案并实施,确保了该给水泵汽轮机的顺利冲转和带负荷。事故分析结论和处理方案对于同类汽轮机的安装、运行和调整都有很好的借鉴。By the vibration analysis of a steam turbine of feed water pump used for a 300MW unit, this paper provides that the expansion of the exhaust pipe of the steam turbine is restricted and its drain system is blocked which is main reasons of the malfunction. This paper presents the concrete disposal measures and put it in practice, which deal with the malfunction successfully. The analysis and treatment measures of the steam turbine can be good reference for the same type turbine.
