高扬程泵站水锤消除器特性的试验研究

Test and Research on Properties of Down-opened Water Hammer Arrest at High-lift Pump Station

摘要: 为有效防止高扬程泵站机组因意外失电发生水锤事故,引起水大量倒流、机组逆转,对山西杨范泵站采用的下开式水锤消除器水力特性诸参数进行了现场测试与分析,同时采用特征线法模拟,在计算机上编程进行理论计算分析对比,结果表明实测值与理论计算值基本吻合。说明:该数值模拟方法可用于解决类似复杂边界条件的水力过渡过程计算;泵站使用的水锤消除器消锤效果良好。

Abstract: Accidental power interruption at high-lift pump station often causes water flowing backward and machine running inversely. This is called water hammer accident. In this paper, a simulation and spot tests were given in a down-opened water hammer arrest at shanxi yangfan station. The results show that the arrest had a good performance.
