硫酸泵的机械密封失效问题
Reply #62018-07-04
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PLAN3,拆解后原因为硫酸较脏,含固体颗粒,特别是硫酸和乙炔反应,容易形成碳化物,造成机封弹簧卡住,无法给予补偿量,请各位专家给予指导!谢谢!

现在用的机封是金属弹簧结构吧,考虑改用大弹簧或波纹弹簧结构的,抗阻塞性能会好一些

换成PLAN3会呢?加个分离器?
Reply #92018-07-04
可以采用PLAN3,
Reply #102018-07-04
刚刚查了下,硫酸密度大约是1.8,有点大,一般积碳虽然没数据,估计也就卡.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
Reply #122018-07-04
也更换过大弹簧也还是不行!
Reply #132018-07-05
改为PLAN53A方案试一下吧
Reply #142018-07-05
那成本马上就上几个档次了。:lol
Reply #152018-07-05
试一下弹簧不与介质接触的的密封结构。

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
