你是用的单端面的还是双端面的

介质内杂质比较多; 泵运行工况与实际工况相差较多; 机泵的机械密封方案有问题

C3、C4介质压力较高,国产机械密封很容易坏。

现在都是双端面密封了,很少露

这种介质饱和蒸汽压大,为保证液态输送,管网加压,泵中压力也大,密封腔压力也大,密封易损坏,泄露,此外输送过程中如果压力不够可能导致介质汽化 泵无液空转,密封干磨

确实如此,建议升级到串级密封更可靠。

. 我们单位C3液化气用的屏蔽泵

. 其实这代表了一种观点,不仅仅适用泵行业。较新型的设备出现之后,必然会在某些领域里面替代原有旧设备,这也是新设备产生的土壤。8楼以前是属于治标不治本的方法。提高核心竞争力,不做突破很难。

. 输送液态烃介质泵属于高危介质泵,密封采用传统单端面机械密封已经不能满足生产和安全、环保要求了,因此需进行升级改造:采用双端面密封、干气密封;完善冲洗方案;增设泄漏密闭排放系统。

. 建议用屏蔽泵,使用效果很好!

这种介质汽化压力大,易汽化,对温度敏感,属于一种有难度的工况,密封容易损坏是正常的。
