自六十年代以来,机械密封作为摩擦学领域的一个分支取得了一系列的研究成果,得到了迅速的发展。总的来说,对机械密封的研究可分为两大类:一是从“小”的方面,着眼于机械密封之摩擦端面;另一是从“大”的方面,着眼于机械密封动、静环本身。表1列出了机械密封的主要研究方面。从国内外文献资料来看,前一类的研究课题受到了更多的重视,这是因为:(1)机械密封实质上是密封与润滑或泄漏与磨损这对矛盾调和的结果,评价其性能的标准是
Since the 1960s, mechanical seals have gained a series of research achievements as a branch of tribology and have been rapidly developed. In general, the mechanical seal can be divided into two categories: First, from the “small” aspects, focusing on the mechanical seal friction end; the other is from the “big” aspects, focusing on the mechanical seal, Static ring itself. Table 1 lists the main research aspects of mechanical seals. From the domestic and foreign literature, the former type of research subject to receive more attention, this is because: (1) mechanical seal is essentially sealed and lubricated or leakage and wear of the results of this conflict to assess its performance The standard is
