干气密封技术国产化的应用与发展

Application and Development of the Localization of the Dry Running Gas Seal Technology

干气密封技术是一种典型的零污染密封技术,对现代工业产生很大影响,我国干气密封技术从20世纪90年代开始起步,经过一系列的摸索与实验,现已取得了长足的进步。文章阐述了干气密封的原理及应用,着重介绍了某装置干气密封技术国产化升级改造典型案例,最后对干气密封国产化技术的应用与发展进行了展望。

The dry running gas seals technology is typical a kind of non-polluting seal technology,which has a great influence on the modern industry. The dry running gas seal technology inchina was started in the 1990s,and after a series ok explorations and expriments,it has made considerable progress.This the sis ex- pounds the principles and applications of the dry running gas seal, emphatically introduces a typical case of localition up grade and retrofit of the running gas seal technology in some unit and prospects the applica- tion and development of the try running gas seal technology.
