摘　　要：通过理论和工程实践两方面研究了转子不平衡、刚性联轴器连接不对中的故障机理。结合炼油厂的实际情况构造了针对大功率自润滑滑动轴承支撑电机现场高速动平衡系统,实现了此类电机转子微小不平衡现场处理。并对如何提高多套大功率大制冷螺杆制冷机组的运行水平、控制噪音进行了探讨。In this paper, theoretical and practical aspects of the rotor imbalance, misalignment of rigid coupling to connect the failure mechanism. Combined with the actual situation in the refinery constructed self-lubricating plain bearings for high-power motor on-site support high-speed balancing system, realized that such small rotor imbalance the scene, and how to improve the sets of high-power large refrigeration screw chiller operating level, control of noise was discussed from various aspects.
