摘要(Abstract):

介绍了转子泵用新型零逸出非接触式机械密封的工作原理和技术优势 ,综合了其最新研究及开发成果 ,简要给出了其各自的使用条件及范围 ,旨在推动干气密封和上游泵送机械密封在国内石油石化等工业领域转子泵上的推广使用。
Mechanisms of non emission non contacting mechanical face seals, such as dry gas seal and upstream pumping seal were indroduced; the working conditions, the industrial application areas and the developments of them were analyzed. It is believed that the non emission non contacting mechanical face seals will play an important role in industrial application as rotary pump seals.
