流量增加意味着电流增加,为什么在泵滤网堵塞时流量变低还超电流。
Reply #22011-06-30
又不是只有流量增加才会超电流,其实如机械原因,绝缘问题也会引起超电流的。

本帖最后由 lijlaşhuai 于 22111-7-1 11:33 编辑 流量增加靠什么?靠泵的功率增加啦,电流当然会超。进口滤网堵塞怎么办?泵自然是要增加功率加大吸入量呀,那电流还不超?二楼的兄弟说的好,还有其它原因,譬如机械原因,如果同轴度不好,自然增加了泵所需的功率,电流当然会超啦。。。。

上楼兄弟所说滤网堵轴功率大,那你把入口阀关小看轴功率会大吗

阻力增加,需要动力增加。电机功率增加,到了极限就是一端闭死,不就“憋泵”了么
