最近有台泵的选型遇到了麻烦。介质是易燃易爆的液体,密封要求可靠;含有约15%盐结晶;还有微量的气体。温度100多摄氏度,操作压力两公斤。 请提供宝贵意见。

开式叶轮,双端面带压密封系统

含有盐结晶,磁力泵的隔离套会受不住吧。

流量小可以用切线流泵,54+62方案

请注明是否要求连续运行,如果是间隙运行,频率不高的话,推荐使用双隔膜带报警的气动隔膜泵

隔膜泵不耐温把,有点难选

副叶轮加双封!学渣浆泵上的密封结构!渣浆泵都能用你这个也没问题!

流量稳定,可以用离心泵,选开式或半开式叶轮,机械密封,冲洗方式用11+52+62方式

看具体值,主要是影响垫片材料,楼主说的100多度,范围太大,超过140度就难选了

各位的建议很有帮助。接下去就要去找对口的泵厂家深入咨询去了:handshake

必须提供流量,扬程,物料成分,操作温度,比重,固体名称等,才可以选择合适的泵。

据我所知,隔膜泵最大耐温100度
