摘　　要：对于 2 0 0 MW汽轮机给水泵组较复杂的振动问题 ,可通过频谱测量和推理分析来解决 ,并结合实例准确地找出汽机给水泵组的振源及传递媒介。提出改进措施实施后 ,收到了较满意的效果。图 6表 2参The treat complex vibration of feedwater pump for 200MW steam turbine can be solved by means of measure of frequency spectral and analysis diagnose. And combine example can find source of vibration and medium of transfer of feedwater pump for steam turbine exactly, put forward measure of improve, get good result. Figs 6, tables 2 and refs 2.
