安全阀泄漏问题

Reply #52019-03-04

* 容积泵出口管道上上安装了一个安全阀，排放口接在泵的进口管线上，但在泵进口阀门打开时安全阀体连接面和顶部调节螺杆位置都有介质泄漏（没启动泵，安全阀检验之前）请问各位是什么原因?是安装方式不对还是安全阀有问题（这种安装方式的4台安全阀出现问题一样

* 容积式泵的返回管线是否有开度？这样导致泵的进口压力会有所上涨。

* 尽管楼主强调安全阀检验之前，但我认为安全阀不合格。楼主所说的管道状况，我没有理解错的话就是为了避免容积泵出口侧超压而设置的限压回流措施。而泵的进口侧管道正常情况下也会有很高的压力，介质从回流管进入安全阀出口侧，低压的介质如果会泄漏那那那就是安全阀选型不对或者质量不合格
