真空热处理炉的真空系统检漏是生产中经常出现的一个大问题。关于检漏技术有许 多资料介绍。本文重点对真空系统在使用中出现故障时提出了处理方法，就是根据不同 时间、条件进行理论分析，可以判断出漏气可能产生的部位，找到漏孔。由现场经验得 知：用分析法找漏，比用检漏仪检漏即降低成本，又迁就了一般小厂不具备检漏仪器的 不足。而且此法找漏有时又快又准确。 Vacuum heat treatment furnace vacuum system leak detection is often a big problem in production. There are many information on leak detection technology. This article focuses on the vacuum system in the use of the failure of the proposed treatment method is based on different time and condition of the theoretical analysis can determine the possible leakage of gas to find the leaks. Learned from the field experience: Analytical method to find leaks, leaking than using leak detectors that reduce costs, but also accommodate the general lack of small factories leak detectors. And this method to find leaks sometimes fast and accurate.
