The Vibration Analysis and Treatment to one Steam Turbine of Feed Water Pump Used for a 300MW Unit

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.
