摘　　要：针对某600MW机组汽轮机轴系振动偏大问题,进行了振动测试分析,阐述了高中压转子、低压转子Ⅱ和5号轴承座振动故障的特征及原因,在评估机组检修工作对轴系平衡状况的影响之后,采取了预加重的动平衡方式以及柔性转子谐分量动平衡方法进行现场动平衡试验,最终将轴系振动水平降至了优良水平。The vibration cause of HP-IP rotor,the LPⅡrotor and#5 bearing seat for one 660 MW unit were confirmed by test analysis.Field dynamic balance tests were conducted on the unit using pre-weighted dynamic balance method and flexible ro⁃tor harmonic component dynamic balance method.The results indicate that the fault diagnostic analysis and the treatment meas⁃ures are effective.The analysis and handling process of this vibration fault provides guidance for the analysis and treatment of similar faults.
