{"Le sélecteur de la pompe diaphragme est entièrement坏损
Reply #22018-10-10
2{"L'entreprise a installé装置,里面有使用膜泵的地方,参数为11/h,压力为3Kg;管线长3米左右,介质是净水剂(包含有小颗粒的活性炭),运行不到几分钟,单向阀的陶瓷球就把钢的阀座打坏了,瓷球卡在里面不上药了。哪位大神知道这是怎么回事?是泵的选型有问题吗?

不知装置运行时流量要求多少?再者介质中含小颗粒,在阀座位置集聚后影响上量,

球座更换成聚四氟乙烯的看看怎样

与泵厂家联系,调整阀座材质为非金属软材质看看效果,还不行的话,这种工况不适合用膜泵,考虑其他容积泵

陶瓷球完全卡在阀座上导致的上不了量,拿下来试漏阀座也密封。

不锈钢的也不行,聚四氟乙烯太软了。

会不会是因为泵的选型问题呢?

也有可能是泵的质量问题,小立方的小泵,不知道您那边买的哪家的。

是泵的选型有问题,介质中的活性炭小颗粒会研磨阀座。
Reply #112018-11-05
阀座和球的材质是关键问题,目前都是刚性材质,对介质洁净度要求高(含有颗粒肯定不行),球稍被颗粒垫起或者损坏,其密封性就变差,建议更换阀座或者球的材质,包容度大。

建议将进出口止回阀更换成阀板式,杜绝因为颗粒损坏阀球或是阀座而导致设备运行异常。
