alcl3三氯化铝的hcl水溶液,含有有机废水,ph值1左右,输送温度20度,含有固体颗粒,粒径max=2mm,含量1%现在用的砂浆泵,机封总是磨损,环保查得严,想换几台没机封的,不知道屏蔽泵可以吗?或者各个厂家有没有好的推荐?

现在用的什么形式机封?单端面的吗?
Reply #32019-07-06
是现在用的wb2机封,不想用机封的了
Reply #42019-07-06
机封的漏啊,味道也大,环保查得紧
Reply #52019-07-06
屏蔽泵可能需要泥浆隔离型的
Reply #62019-07-06
你这工况有颗粒杂质,WB2机封是用不住,可以用双端面带冲洗的,不会漏。 如果执意用屏蔽泵,只能选泥浆型的,另外价格不菲。

压泥那种YLB型的结构看一下,进口靠机封侧的,相当于机封那边负压

扬程和流量较低建议使用轴流泵

可以借用渣浆泵的结构,选用耐腐蚀的材料

除非就是付叶轮密封有借用价值。

考虑过机封冲洗方案,味大
Reply #122019-07-07
你说的那是压滤机入料泵。

有固体颗粒不能用屏蔽泵,有一种高分子材料的夹板泵完全可以,专门针对含固体颗粒的强酸设计的。
Reply #142019-07-10
2mm直径固含量就不要考虑屏蔽泵了
Reply #152019-07-11
衬氟磁力泵,现场如有外冲洗条件更佳!
Reply #162019-07-12
颗粒太大,渣浆泵没有选错,机封可以考虑做高压冲洗,或者考虑气动隔膜泵。
