您或许是专家,但是提供的线索太少了....... 有压力波动的趋势吗?
Reply #32020-06-19
管路布置一样吗?有没有抢流现象
Reply #42020-06-19
进口过滤器可以检查一下
Reply #52020-06-20
肯定是两台泵的管线走向长度、阀门弯头设置等造成装置状况不一致,导致一台泵抢流运行,一台泵欠流量运行,而造成出口波动,建议检查两台泵流量或电流情况是否是这个原因

1看看旋转方向是否有问题1再查管路
Reply #72020-06-22
两台泵虽然进出口总管是同一根,但是泵的过滤器,进口阀等部件应该各是各的,可以检查一下压力波动那台泵的进口过滤器,看是否有堵塞?

问厂家要一下离心泵扬程流量曲线。如果两台泵并联,要求泵的工作点到闭死点的曲线是连续上升的。且扬程上升的值大于10%为宜。根据您的描述,最可能的现象是你的泵曲线中存在驼峰。

电机转向,止回阀是不是有个不对了
Reply #102020-07-16
问题可能出在阀门、管路、过滤器,仔细排查下

你是2台泵同时启动吗?同时启动估计是其中一台泵扬程不一样,或者出口管线三通连接导致有台泵流量的堵塞的情况!如果是单台调试,搞不好是止回阀内漏了!!
