摘　　要：介绍了核电厂运行过程出现的排风机振动故障情况,通过对振动数据的分析,从而确定振动故障的可能原因。采用设备分解法和正向推理验证法,逐步确定风机振动故障的原因在于轮毂与后盘连接处铆钉锈蚀导致机械松动,并在检修后,电机振动恢复正常,保障了排风机机组的安全稳定运行,为同类型风机检修思路提供参考。This paper outlines the vibration faults of exhaust fans in the operation process of nuclear power plant.Through analyzing vibration data,the possible causes of vibration failure are determined.According to the possible causes,equipment decomposition method and forward reasoning verification method are combined to determine step-by-step that the cause of fan vibration failure is mechanical loosening induced by corrosion of rivet at the connection between wheel hub and rear disk.The motor vibration is restored to normal,which ensures the safe and stable operation of the exhaust fan unit,and provides a reference for the maintenance of the same type of fan.
