摘要
通过对150 NW 78×2型低压加热器疏水泵进行变频调节改造,对轴端密封水系统、转子部件材质和轴套锁母定位形式进行了改进,消除了给水溶氧超标、轴承振动超标和轴承烧毁等缺陷,提高了泵组健康运行水平。
Through the retrofit for multi-frequency regulation,shaft sealing water system,rotator material and shaft cover orientation mode of 150 NW-78×2 low pressure(LP)heater drain pump,pump corrosion at low-load operation,bad packing seal,bearing vibration,bearing burned have been solved.Health operation level has been improved.
