防漏治漏专页开办已近一年了,发表了不少很好的文章。许多文章中提到了一些密封装置的名称,但未给出其结构图。本文试对几种常用的密封装置的名称和结构做一简单的介绍。 1.间隙密封间隙密封(图1)是靠运动副之间微小的间隙和运动件配合表面上均压槽(宽0.3～0.5mm,深0.5～1.0mm)中的储油来进行密封的。有时也可以没有均压槽。显然,这种密封不可避免地存在着微量的泄漏。 Leakage Leakage Pages Opened nearly a year, published a lot of good articles. Many articles mention the names of some of the seals but do not show the structure of the seal. This article tries to make a simple introduction to the names and structures of several commonly used sealing devices. 1. Gap Sealing The gap seal (Figure 1) is sealed by the small gap between the pair of motions and the oil in the equalizing groove (width 0.3-0.5 mm, depth 0.5-1.0 mm) on the mating surface of the moving part. Sometimes there may be no pressure tank. Obviously, this seal inevitably there is a slight leakage.
