摘　　要：针对汽动给水泵转子质量不平衡的形成原因、振动机理和振动特点进行了详细的分析和介绍,以某600MW超临界机组汽动给水泵在运行过程中出现的异常振动过程进行分析和研究,指出转动部件脱落是导致该汽动给水泵异常振动的主要原因,成功解决了汽动给水泵异常振动问题。In this paper, analysis and presentation of the quality unbalanced rotor formed steam turbine-driven feedwater pump reasons, and vibration characteristics of the vibration meehanism, With a 600MW supercritical unit, analysis and study of the steam turbine-driven feedwater pump vibration anomalies occur during the process of operation, pointed out that the main cause of the abnormal vibration of the steam turbine-driven feedwater pump is the failing of the rotating parts, successfully solved the steam turbine-driven feedwater pump vibration anomalies.

关 键 词：汽动给水泵 异常振动 质量不平衡
