泄漏检测技术的研究及夹具设计的优化

Research on Leak Detection Technology and Optimization of Fixture Design

0引言泄漏检测技术在生产中也常常被称作“试漏技术”或密封性检测技术。在发动机行业中，被广泛地应用于有严格的密封要求的汽车发动机、化油器、变速箱、离合器壳、油料箱等的泄漏检测。在其他工业领域如液压、气动、医疗、日用品、家用电器、食品包装、化工、燃气等也有广泛的应用。

Introduce the principle and status of domestic and overseas leak test technology. Regarding to low test accuracy of domestic leak test technology ＆ application, introduce the important engineering points of leak test fixture, which is good reference for engineers of leak test machines.
