可能是流量过小,出现气蚀现象。

进口管线太小,发生气蚀,改大点看看

泵出口没有止回阀对不对?备泵阀门一开还未开泵此泵异响消失。说明在两个泵之间打循环,水从备泵返回到此泵进口,防止了进口压力和流量不足造成的气蚀。

发生气蚀,振动没有一点变化吗?
Reply #92017-08-06
泵体振动大吗?试过停下再开吗?

入口过滤器堵了,清理一下就好。

有没有止回阀没注意,抽空我看一下。不过不是开备泵阀门,没开备泵,是在启动了备泵后,开大备泵的出口阀门时发现主泵异响消失

应该不是,电流正常的,而且现场看阀门开度也不小。如果是小流量应该电流偏小才对吧

管线不能随便动的,暂时也不考虑改,只是提出这个问题,大家一起讨论下原因
