高压高水基棉麻动密封软填料的密封机理分析

The Sealing Mechanism of Soft Sealing Packing under High-pressure and High-water Based Fluid Systems in Dynamic Sealing

本文阐述了新型编织软填料为多束多级节流和多级微间隙流阻效应的双联密封机理 ,由于存在摩擦磨损 ,密封机理是动态变化的。

The sealing mechanism of the new-typed braided soft packing under high-pressure and high-water based fluid systems in dynamic sealing is mainly described in the paper, and its key is double acting mechanism by multistage throttling and flow resistance of micro clearance, and the mechanism is dynamic as well because of friction and wear.
