上游泵送机械密封主要是借用低压流体的主要特性来实现对高压流体密封的一项全新的密封新技术,它所具备的一个最为典型的特点就是在一密封端面开有起上游泵送功能的浅槽。本文主要基于上游泵送机械密封的工作原理,然后阐述其实际的应用,旨在为更好地认识和应用上游泵送机械密封技术提供一定的借鉴与参考。 Upstream pumping mechanical seal is mainly borrowed from the main characteristics of low-pressure fluid to achieve a new sealed high-pressure fluid seal technology, which has one of the most typical features is open in a sealed end of the upstream pumping function Shallow groove. This paper mainly based on the working principle of upstream pumping mechanical seal, and then describes its practical application, which is intended to provide some reference and reference for better understanding and application of upstream pumping mechanical seal technology.
