汽轮机组轴系异常振动研究与处理

Research and elimination of abnormal vibration for shaft systems of steam turbine units

从300 MW机组轴系异常振动诊断入手,通过精确的低压转子现场高速动平衡,一次加重即解决了轴系振动严重超标问题,为分析处理该型机组轴系振动故障问题提供了有效参考。

Based on the abnormal vibration diagnosis for the shaft system of a 300 MW unit, the accurate field high speed dynamic balance technique was used in the low pressure rotor to solve the serious vibration problem, and the result was satisfactory.
