注意,以下文本中的技术术语需要保持一致,例如“单级双吸离心泵”应翻译为“단일 단계 복수 흡입 펌프”,不能随意翻译。请按照此格式返回JSON数组。

随流量增大,扬程降低,电流未增大反而减小,说明未处于过载工况。水泵随流量增大,必须汽蚀余量也增大,泵进口压力应该是小于大流量工况点的必须气蚀余量,所以会发生汽蚀,出水小了。

关系统未端阀门,压力就可以上来了!

流量值已经远超额定流量,泵发生汽蚀,所以电流降低,建议在额定点运行看看参数,如果还不满足使用要求,那就是选型问题了

关小阀门至30,泵前压力大了,总管压力没上

设备是看压差的,你的设备管损是多么?或者私聊我一下

3000方的泵搞到4500了,还要求啥

可以临时采取点措施,减少管道出口面积。

这相当于让一匹马拉俩马车,本来就够累了,你还想让它跑的快,你就用鞭子抽它,到最后不管怎么抽它都只跑那么快,还问别的马夫我的马为啥跑这么慢?
