摘　　要：受核电站一回路复杂运行工况的影响,一回路冷却剂泵(下称“主泵”)经常发生振动高的问题,现场动平衡是解决主泵振动问题的重要手段,也是影响和制约核电站机组启动上行的关键因素之一。通过对大量同类型主泵动平衡数据的总结,提出了主泵动平衡的一次加准方法。该方法给出了CPR1000机组主泵动平衡中加重质量、加重角度和残余振动的计算方法,通过一次加重达到预期振动控制目标。该方法的应用能够极大节约现场动平衡试验的时间,缩短维修工期,对机组的安全稳定运行及核电站的经济效益具有重要的现实意义。The vibration problem of the primary coolant pump occurs frequently due to the complex operation condition of the primary coolant circuit.The dynamic balance test is an important measure to reduce the vibration level.The dynamic balance result seriously affects and restricts the unit start-up process.A one-step dynamic balance method was developed based on abundant dynamic balance data of the same type pumps.The one-step dynamic balance method provides calculation method to define the weighting value,angle and residual vibration amplitude.The application of this method has an important significance to the safe,stable and economic operation of nuclear power plants by saving the dynamic balance time and shortening the maintenance period.
