摘要
上游泵送机械密封是利用低压流体实现对高压流体密封的一项新的密封技术 ,它的典型特征是在一密封端面开有起上游泵送作用的浅槽 ,利用流体动压效应使得两密封端面被一完整的流体膜分开 ,这极大地改善了密封端面的润滑状态。本文介绍分析了该类机械密封的基本原理。
Upstream pumping mechanical seal is a new technology that successfully seals a high-pressure fluid by a lower pressure fluid.Its typical characteristics is that some hollow grooves with upstream pumping ability are etched on one of the seal faces and the two seal face are separated by a complete fluid film by the fluid hydrodynamics,which extremely improves the lubrication of the seal faces.The fundamentals of this kind of mechanical seal were introduced and analyzed in the paper.
