摘　　要：介绍了某电厂一台9F级单轴联合循环机组高压缸出现的严重碰摩故障,分析了该故障的振动特征、诊断方法和检修处理情况。机组检修结果表明该故障的主要原因为高中压转子轴向定位尺寸K值与设计值偏差较大。High pressure casing of one 9F combined cycle power train occurred serious rubbing in commissioning period. Vibration characteristics, diagnosis method and treatment of that rub were discussed with date records. The treatment result showed that the key reason of rub was HP rotor axial position ＂K＂ value seriously deviated from the design value.
