我公司使用80YG-60的管道泵卸甲苯、二甲苯这两种物料,很容易抽空损坏103-45弹簧式的机械密封(1个月大约更换3到4次的密封),该密封采用的是软对硬端面,现想解决这个问题,我考虑更换转子泵,但转子泵达不到防爆的等级,现急需更换泵,各位大神、老师傅、老司机有什么好的建议。

用动力密封或无密封的泵啊

机械密封可以加53系统,保证密封面上有液膜

不从解决抽空问题角度考虑,任何形式的泵也满足不了要求。

在泵的入口处加缓冲罐,罐内加上液位开关,液位低了自动停泵!罐的体积为入口管道总体积的3-5倍即可!

也考虑过这个问题,当时想将弹簧密封改回波纹管的密封,不知道这个可不可以

也考虑过增加缓冲罐,但是卸车高度与泵的高度差不允许

动力密封管道泵或者自吸泵,无密封立式泵啊
