摘要
通过对襄樊电厂3号机组低压转子叶片1次断裂和汉川电厂2号机组低压转子叶片3次断裂的准确故障诊断及处理,定量分析了叶片断裂故障的振动诊断机理,得出了叶片断裂的振动故障特征,并提出了叶片断裂故障的现场处理对策,为进一步诊断分析同类故障提供借鉴和依据.
Through accurate fault diagnosis and handling for once low-pressure rotor blade failure of Unit 3 in the Xiangfan Power Plant and three times low-pressure rotor blade failures of Unit 2 in the Hanchuan Power Plant, the vibration diagnosis mechanics for blade failure fault was quantitatively analyzed and the vibration fault characters for blade failure fault were summarized. Further more, the countermeasures for blade failure fault handling on site are given to provide reference and accordance for further diagnosis and analysis of the similar faults.
