发动机零部件气密性检测及其装备关键技术

摘要

Air tightness testing of engine parts can ensure engine quality and reduce waste product. By analyzing the air tightness testing principle and contrasting the performances of domestic and external air tightness testing detectors, the main parameters of engine parts air tightness testing design were proposed. It was pointed that flexible, networking, temperature compensation were the key technologies of leak detecting machine development.%发动机零部件气密性检测是保证发动机质量、减少废品的重要保证.通过分析发动机气密性检测原理及对比国内外气密性检测仪性能,提出发动机零部件检漏机设计需要考虑的主要参数,指出柔性化、网络化和温度补偿等是检漏机发展的关键技术.
