200MW机组振动分析及处理

Analysis and Treatment of 200 MW Turbine Generator Unit Vibration

苏制 2 0 0 MW机组大修低压缸改造后 ,高、中压转子轴振和低压转子瓦振严重超标 ,通过振动测试分析 ,查明了引起振动的原因 ,并进行了处理。

After the overhaul of the soviet turbine generator set,the rotor axes vibration of high pressure and middle pressure and the axes bushing vibration of low pressure are more seriously than normal.By testing and analyzing of the vibration,find the reason that caused the vibration,and give treatment.
