旋转设备动平衡试验中若干问题的分析

Issues to be Paid Attention to during the Dynamic Balance Test of Rotating Equipment

通过旋转设备动平衡的实践,提出0°相位的意义及确定方法;针对汽轮机检修后轴系平衡状态变化的原因进行了分析,提出了动平衡的优缺点;对于小型悬臂式离心风机振动问题,分析了动平衡过程中的注意事项;通过凝结水泵的动平衡案例,分析了立式旋转设备的平衡特点。

In this paper, the significance of the 0° phase and its locating method are elaborated through the practice of dynamically balancing the rotating equipments. The reason of shaft balance change after the maintenance of the turbine is analyzed, and the advantages and disadvantages of the dynamic balance are proposed. The precautions in the balancing process in terms of the small cantilever centrifugal fan vibration are analyzed. Through the analysis of dynamic balance of a condensate pump, the balance characteristics of vertical rotating equipment are analyzed.
