摘要(Abstract):

针对汽轮机低压缸末级叶片在恶劣工况下长期工作的情况 ,采用对末级叶片实测其静频率 ,建立一片一户专门档案的方法 ,用于评估和预测叶片运行的可靠性。实践表明 ,该方法可靠有效 ,保证了机械的长期安全运行
With regard to severe working conditions long time suffered by the rear blades inside the low pressure cylinders, measurements of static frequency have been taken to evaluate and predict the operational reliability of the said blades by means of establishing one blade corresponding to one file. Being maintaining the long term safe operation of the machine the practice shows that this method is workable.

关键词(KeyWords): 叶片;安全;可靠性
