摘　　要：通过对高压液氨泵驱动侧工频故障原因的分析,得出高压液氨泵存在转子动不平衡问题,并通过改进转子动平衡驱动方法,合理选择动平衡校验转速,成功将转子动不平衡量降低到设计允许最大动平衡量以下,解决了高压液氨泵驱动侧振动异常的问题。By analyzing the reasons for power frequency failure on the driving side of high-pressure liquid ammonia pump,this paper concludes that the high-pressure liquid ammonia pump has the problem of rotor dynamic unbalance.By improving the dynamic balance driving method for the rotor and rationally selecting dynamic balance check speed,the dynamic unbalance is successfully reduced to below the maximum dynamic unbalance allowed by design,thus solving the abnormal vibration problem on the driving side of the high-pressure liquid ammonia pump.
