机械装备在使用过程中,由于密封失效,常常会出现漏油、漏水、漏气等现象。这些现象轻则造成物质上浪费,降低机械的工作效率,并造成环境污染等不良后果;重则可能造成严重的机械事故。因此,保持机械良好的密封性能非常重要。对于密封失效的原因,除使用过程中的磨损、变形、老化、 Mechanical equipment in use, due to seal failure, often there will be leakage, leakage, leakage and so on. As a result, these phenomena cause material waste, reduce the efficiency of mechanical work, and cause adverse consequences such as environmental pollution; in the worst case, serious mechanical accidents may result. Therefore, it is important to maintain a good mechanical seal. For sealing failure reasons, in addition to wear and tear during use, deformation, aging,
