本帖最后由 3983596_FPPZ 于 2019-6-12 14:36 编辑 同样的性能参数,两极电机转速的泵要比四极转速小些,成本更低些,但是因为是自吸泵,所以自吸泵体腔体大小是根据流量设计的,两极四极应该差别不大。 超版泡沫也提到了,既然自吸泵,更应该关注泵的汽蚀余量大小,选型时,除了满足流量扬程外,应优先选择汽蚀余量更小的泵,从而获得更大的自吸能力和吸上安全余量,保证在实际使用过程出现任何的异常状态下泵仍旧能够有效使用。

你这和自吸泵有什么关系么,是电机问题啊,你选型有什么问题?

不要用自吸泵,效率低。你可以用真空引水罐加管道泵模式。

这个型号 二级气蚀 声音应该是不小

入口条件没给全 ,如果就吸个1米以内的高度2级电机可以凑合着用,超过1米还是老老实实的选4级电机的吧
