核电厂循环水泵轴封水压力波动问题分析及应对措施研究
发布时间：2018-12-10 20:00
【摘要】：循环水泵轴封水的作用主要是冷却循环水泵和冲洗带走泵轴旋转摩擦产生的细小铁屑等杂质。某核电厂循环水泵的轴封形式为唇形密封,当轴封水压力低于设定值会自动停止循环水泵,将触发停机,严重影响机组安全性和经济性。该问题处理适用于类似问题的应用借鉴。
[Abstract]:The main function of circulating pump shaft sealing water is to cool the circulating pump and wash away the impurity such as small iron chip produced by rotating friction of pump shaft. The seal form of circulating water pump in a nuclear power plant is lip seal. When the water pressure of shaft seal is lower than the set value, the circulating water pump will be stopped automatically, which will trigger the shutdown, which will seriously affect the safety and economy of the unit. The problem treatment is applicable to the application of similar problems.
