近些年来，越来越多的离心压缩机不平衡问题通过现场动平衡得以解决，现场动平衡的作用也越来越凸显出来。离心压缩机转子属于高速柔性转子，动压滑动轴承支撑，利用膜片或膜盘联轴器柔性连接，因此现场动平衡与普通刚性转子或低速柔性转子有所不同。离心压缩机的生产工艺流程复杂，现场动平衡时也有诸多事项需要注意。文章结合近百次离心压缩机现场动平衡的实践经验，对离心压缩机现场动平衡的实施情况、发挥的作用、若干关键技术、出现问题如何应对、发展前景等进行了全面的总结，希望对故障诊断工程师或设备管理人员有所借鉴或帮助。

In recent years, more and more unbalance problems of centrifugal compressor units have been solved by field balancing, of which the role has been increasingly emphasized. The rotor of the centrifugal compressor is a high-speed flexible unit that is supported by dynamic pressure bearings and flexibly connected by diaphragm or diaphragm disc coupling. Therefore, the field balancing is different from the rigid rotor or low-speed flexible rotor. The production process associated with the centrifugal compressor's driving operation is complex, and many matters need to be paid attention to during the field balancing. Based on the experience of field balancing of centrifugal compressor units for nearly hundred times, this paper makes a comprehensive summary of the implementation of field balancing, its role, several key technologies, how to deal with problems, and development prospects, from which it is hoped that the fault diagnosis engineers and device management personnel can learn or get help.
