Research of a Pressure-difference High Precision Micro Air-leakage Detector Based on Cubage Compensation

基于容积补偿的差压式检漏法与普通的差压式检漏法相比,具有精度高、测试速度快等优点。本文作者介绍了基于差压式容积补偿检漏装置的工作原理,实验对比了无容积补偿的普通差压法与基于容积补偿的差压法的测试结果,并做了相应分析。

Pressure-difference leakage detection based on cubage compensation has the virtues of high precision, fast testing compared with ordinary method. The principle of a pressure-difference leakage detector based on cubage compensation was introduced. Experiments were made to contrast the pressure-difference leakage detection based on cubage compensation and without cubage compensation, and analysis for the corresponding tests was given.
