摘要
大坝发电厂4台300MW机组,共8台汽动给水泵,4台电动给水泵,经常出现因机械密封液温度高而报 警,甚至跳泵的现象,经分析原因后实施了机械密封冷却系统的改造,针对改造措施,从原理、原因、改造方案及 遗留问题等方面进行探讨与分析。
The CHTA feed-water pumps in the Daba Power Plant always warn caused by the high temperature of mechanical seal liquid, by analyzing the cause of fauh, puts forward improvement schemes, and rebuilds the mechanical seal cooling system.
