| 摘 要： | 分析了质量不平衡故障机理、原因和振动特征,针对某电厂2号600 MW超临界机组9号瓦及1号瓦轴振大的问题,进行了测试和分析,判断1号、9号轴瓦轴振大为不平衡量增大所致,分析了引起不平衡的原因。根据诊断结果,对1号、9号轴瓦进行了动平衡和抽高中压转子返厂处理。并与同类故障进行比较,给今后相似故障的分析处理提供参考。 |

| Abstract: | The mechanism,reasons and vibration characteristics of the imbalance fault ware presented,and a 600MW supercritical unit with bearing vibration fault was monitored and analyzed.Determined the vibration fault of No.1 and No.9 bearing due to mass imbalance increases,and analyzed the reason of imbalance.According to the fault diagnosis result,balancing are carried out,and High-medium pressure rotor was returned to the manufactory.Then compared with similar faults,the case will be as a reference to the same type of units with similar vibration faults in the future. |
| Keywords: | supercritical unit mass imbalance fault diagnosis |
