汽轮机振动故障机理分析

Fault principles analysis to the vibration of the turbine

大型汽轮发电机组是火力发电厂最重要的设备之一 ,而汽轮机组的振动也一直是其主要故障。汽轮机振动过大对机组的危害性极大 ,直接影响电厂的安全经济运行。

A large turbine-generator unit is one of the most important device in power plant. The vibration of the turbine-unit is its main fault. The turbine's vibration is too larger to destroy greatly the turbine-unit, It will influences directly the safety and economical running of the power plant.
