“三漏”(漏油、漏水、漏气)是机械产品的三个顽症。它不仅直接影响产品的性能,而且会严重影响产品的可靠性及寿命,给用户带来巨大的损失。虽经多年努力,“三漏”现象有所减少,但仍未能根治,有些产品上还相当严重。所以,根治“三漏”是当前一项紧迫的任务。 据我公司统计,“三漏”故障约占整个产品故障的30％。引起“三漏”的原因比较复杂,设计不合理、制造误差、装配不当、密封件质量低劣或用户使用不当均能引起。下面就“三漏”的原因及防治作一论述。 “Three leaks” (spills, leaks, leaks) are three chronic diseases of mechanical products. It not only directly affect the performance of the product, but also seriously affect the reliability and life of the product, to the user a huge loss. Despite years of hard work, the phenomenon of “three leaks” has been reduced but still not eradicated. Some products are still quite serious. Therefore, to cure “three leaks” is an urgent task now. According to my company’s statistics, “three leaks” failure accounted for about 30% of the entire product failure. Caused by the “three leaks” for more complicated reasons, the design is not reasonable, manufacturing errors, improper assembly, seals, poor quality or user can cause improper use. The following on the “three leaks” of the reasons and prevention to make a discussion.
