软填料密封机理分析

软填料密封结构简单，历史悠久而应用广泛，但对被密封流体通过软填料密封的泄漏机理和软填料密封的密封机理并没有完全认识清楚。本文初步分析了流体通过软填料密封的泄漏机理和使软填料密封具有良好密封性能的基本要求，并澄清了有关软填料密封机理的一些模糊认识。

An Analysis of the Sealing Mechanism of a Soft-Packed Stuffing-Box Seal

The soft packed stuffing box seal with a long history is simple and still widely used, but it is still not very clear that as to how the sealed fluid flows through the seal and what the real sealing mechanism is This paper presents a fundamental analysis to the leaking mechanism of the sealed fluid leaking, and the fundamental requirements in order to make the seal be with good performance It also clarifies some obscure concepts of the sealing mechanism of a soft packed stuffing box seal
