请教各位大神,对于输送高浓度酒水混合液体的离心泵应选何种机封?系统压力5-6公斤,介质温度90度,酒精易气化所以泵内常有气蚀现象。

可以采用双端面,使用水作为冲洗液,plan53A 54 方案

斑竹在机封及冲洗方案方面特别擅长,值得学*,顶一下

建议用PLAN21+53A(或B)的方案。

之前用的就是双端面密封,但是总会出现漏料的现象,酒水会从机封水露出来
Reply #72018-09-26
那你双端面后面的系统压力是多少?
Reply #82018-09-26
我看还是换屏蔽泵吧,海密梯克的就有专门输送易汽化介质的

泵的进口压力多少,泵的型号,扬程。我需要计算一下密封腔腔压。

现在使用机封摩擦副是什么材质
Reply #112018-09-26
泵进口微正压,型号IH125-80-250,扬程是60米,流量120

叶轮后盖板带的背叶片吧或口环加平衡孔的,如果是回水压力3公斤倒也够了,泵振动大吗?你们检修看到的密封是什么状态,环面干磨吗?

没多么复杂,就是介质端摩擦面存在气蚀干磨现象,解决也很简单。应该选用,双端面平衡型机械密封。单端面也可以用,必须加PL-11方案冲洗,如果有条件21方案最好。
