易汽化介质泵用密封的改进

Improvement of Pump Used Seal for Easily Gasifi ed Mediums

易燃易爆等易汽化的介质在石化行业很常见,在化工生产过程中泵用普通结构的机械密封经常会出现因泄漏而造成环境污染,甚至出现燃烧、爆炸等安全事故,需要对机械密封的结构和密封材料进行优化配置,采用合适的密封结构参数,使用合适的密封辅助系统方案,保证设备正常运行,从而保证整个生产装置安全稳定。

Explosive and flammable mediums are commonly used in petrochemical industry. In chemical production, leakage often occurs when ordinary mechanical sead used in pumps that will result in environment pollution and even accidents of fire and explosion. Thus it is necessary to select appropriate seal structure parameters and seal auxiliary system so as to ensure the normal operation of equipment and the safety and reliability of whole plant.
