摘要
某热电厂11号、12号汽轮机正常运行中出现3次振动异常。通过轴系振动测试分析和振动趋势分析,结合汽轮机轴系动力特性及故障特征,正确诊断出汽轮机低压转子发生了叶片断裂事故,避免了事故扩大及二次损坏。
Three abnormal vibrations happened in the normal operation of 1 1th and 12th turbines of certain thermal power plant.By the shafts vibration test analysis and the vibration trend analysis,combined with the shafts dynamic characteristics and the fault characteristics,the blade fracture of the turbine LP rotor has been diagnosed,which avoided the spreading of accidence and the secondary damage.
