摘要
干气密封是从气体动压轴承的基础上发展起来的一种新型非接触式密封,它最初应用于离心式压缩机轴封。介绍了干气密封的特点及工作原理,指出影响干气密封性能的主要因素,对干气密封技术运用于聚酯高温热媒循环泵进行了总结和归纳。
The gas-seal is a kind of new non-contact seal which is developed on the basis of gaseous dynamic pressure bearing and is first being used on the centrifuge compressor. The assay mainly summarize the technique of the further application of dry gas-seal on the high temperature HTM circulation pump.
