| 摘 要： | 珠海发电厂2号机组电动给水泵在每月的定期试验启动过程中出现电动给水泵轴振(X/Y方向)高高的现象,多次导致电动给水泵跳闸。为此珠海电厂组织技术人员对在不同负荷下、不同勺管开度下的电泵启动过程中的振动情况进行监测分析,从而得出结论:电泵启动过程中振动高的原因是电泵的上下壳体温差大。根据分析结果对电泵采取相应的措施,取得了理想的效果,排除了电动给水泵不能正常备用的安全隐患。

| Abstract: | MBFP(Motor Boiler Feed-water Pump)of Zhuhai power plant unit 2 encountered excessive shaft vibration(X/Y side)during periodically start up test.Therefore ZHPS technique analyze the vibration of MBFP under variable load condition,variable H/C(hydraulic couple)demand.It is concluded that the vibration of the MBFP is aroused by the higher different temperature of MBFP upper/lower barrel metal.A treatment is made based on the analytical result and satisfactory result is obtained.Eliminate the defect that MBFP could not in good standby condition. |

| Keywords: | MBFP vibration HH upper/lower barrel metal different temperature |
