摘要
介绍了机械密封中不可视挥发逸出物的控制及其控制逸出量的阻塞和缓冲密封系统，文中着重阐述了零逸出量、干运转密封以及气体的阻塞和缓冲密封系统等新概念。另外，还简介了国外泵和压缩机等转动机械中机械密封控制逸出量的应用指南、密封系统布置、流体阻塞或缓冲密封系统、阻塞流体和缓冲流体及其控制系统，以及国内外研制和生产干运转控制逸出量等的有关情况。
Abstract in this Paper,the control of fugative emission which cannot seen by naked eyes and emissions controllable barrier and buffer sealing systems are presented.Attentions have paid to introduce such new concepts as zero-emissions,dryrunning and gas barrier and buffer sealing systems.In brief presented guidelines for meeting emission regulations for rotating pumps and compressors with mechanical seals,arrangement in fluid sealing system,fluid barrier & buffer sealing systems,barrier fluids and buffer fluids and their control systems.Finally,the emission control dry-running gas barrier or buffer sealing systems developed and produced by foreign and our country are also given.
