悬臂泵停泵反转问题
Reply #42018-09-24
我厂里三台并联运行的离心式悬臂泵,用的止回阀是H7H升降式对夹止回阀,其中一台停泵的时候反转是什么原因?止回阀都换的新的。。

忘记说了 是垂直的管道,水自下而上。是不是这种止回阀只能装在水平管道上?
Reply #62018-09-24
反转肯定是有液体倒流了,出口阀门还有跨接吗?没有的话只能是止回阀未关严了
Reply #72018-09-24
除非三台新的都有问题。。而且不是一个厂的阀门
Reply #82018-09-24
你不信那我也没有办法,你就相信新的东西不会出问题好了,那你慢慢排查吧

正常停泵泵反转是出口止回阀出了问题导致介质回流造成泵反转,其他还真想不出什么原因。建议建议检查止回阀

止回阀是新的,不会出问题的,除非三个都出问题
Reply #112018-09-26
新换的的也不一定就能关死啊,
Reply #122018-09-26
三台泵扬程一样吗?三台泵同时运转吗?
Reply #132018-09-26
不但要检查止回阀,严重的影响叶轮背帽松脱导致机封漏水
Reply #142018-09-26
为什么新的就保证一定没有问题呢:o 额,,,才看懂这个回复:

不不信实际情况,非要相信新的不出问题。

新手机可能开不了机呢;P

泵反转原因肯定就是流体导致的,除非你电机带动了,电机没开那就是介质导致反转。有流体就说明管线是联通的。那你说你的止回阀还能是好的么?阀是新的,那阀有没有装反呢?
