硫酸泵的机械密封失效问题
Reply #42018-07-03
各位专家:我们公司一个装置使用的硫酸泵机械密封总是失效,机封冲洗方式为PLAN

可以采用PLAN32,

刚刚查了下,硫酸密度1.8,有点大,一般积碳虽然没数据,估计也就2左右或者大一点,的确达不到最好的效果。 不过对提高密封寿命应该有一定帮助吧。

差这么点的话,分离不出来的。需要采用别的方式来提高密封的寿命

也更换过大弹簧,还是不行!

改PLAN53A方案试一下吧
Reply #102018-07-04
那成本马上就上几个档次了。:lol

试下弹簧不与介质接触的密封结构。

分两路一用一备,加Y型虑,加排放阀,定期切换清理。 这个成本低

如果工艺允许的话可以用水加个外冲洗试试。个人意见,仅供参考
Reply #142018-07-05
引一路干净的硫酸作为PLAN32冲洗源试试
Reply #152018-07-05
换成PLAN 32就好了

条件允许的话,考虑无密封泵。
