分析了胜利炼油厂气体分离装置丙烷泵工况条件 ,针对该泵研制开发出新型的非接触式零逸出上游泵送机械密封。工业应用结果表明 ,新型的上游泵送机械密封可实现丙烷等易挥发性介质的零逸出 ,基本消除对环境的污染 ,且具有安全可靠、使用寿命长、运行费用低等优点 ,在轻烃、液态烃类介质泵上具有广泛的推广应用价值。
The condition of propane pump in Shengli refinery gas separation plant was analyzed. A new type of non-contact zero-slip upstream pumping mechanical seal was developed for this pump. The industrial application results show that the new type of upstream pumping mechanical seal can achieve zero escape of volatile medium such as propane and basically eliminate the pollution to the environment and has the advantages of safety, reliability, long service life and low running cost. In the light hydrocarbon , Liquid hydrocarbon medium pump has a wide range of promotion and application value.
