摘　　要：运用振动机理分析,查明了DG500-180给水泵轴瓦振动的主要原因是该泵导叶套与叶轮轮毂的碰磨,采取将导叶套、叶轮轮毂配合间隙适当放大的方法,成功解决了同类型4台给水泵轴瓦振动,对于其它多级水泵的振动消除具有重要的参考价值。Through analyzing the vibration mechanism, the paper finds out the main reason of DG500 - 180 feed water pump bearing vibration is the rub and impact between guide vanes and impeller hubs. After increasing the clearance between them, four same - type pumps which occurred same problem has been solved. It has important reference for eliminating vibration in other multi - stage pumps.
