原本用的泵是磁力泵,故障率较高,准备更换为屏蔽泵,请问屏蔽泵在卸车后期含有部分气相的情况能否请问运行?如何选型,有什么注意事项。出口压力0.6MpaG,流量14.5,杨程60m

本帖最后由 大漠的云 于 2018-11-21 13:45 编辑 如果卸车时有气相现象屏蔽泵也用不好,你可以试试在泵前加装一个自吸桶(或者叫缓冲罐),罐体的大小要根据泵的输送流量计算,希望能帮到你:)

入口是负压吗?扬程60米的硫酸泵,出口压力怎么能是0.6MPA?
Reply #42018-11-21
要么提供的参数有误,要么是气液混输,正常泵理论已经不适用了
Reply #52018-11-21
入口就是汽车罐车,常压
Reply #62018-11-21
数据应该错了,60m的杨程到不了0.6mpa表压。忽略60m杨程。怎么选型

双隔膜带报警的气动隔膜泵
Reply #82018-11-23
常规的隔膜泵没有问题,材质316就可以
Reply #92018-11-30
1.屏蔽泵不可以,因为轴/轴承不能耐空转 2.现有的磁力泵,配个防干转保护器,就可以防止空打造成的故障。价格很低,不到3000块

有流量扬程找个厂家的样本参考曲线就可以选型; 至于后期有气相尽量将出口阀相应关小些回避损害,选择气蚀性能好一些的泵!
