Permeator de gaz presiune diferențială

Principiul testului

Instrumentul adoptă principiul testului de presiune diferențială. Proba pre-tratată este plasată între camerele de testare superioare și inferioare și fixată strâns. Firstly, Camera de joasă presiune (Camera inferioară) is vacuumized, and then the whole system is vacuumized. Când este atins gradul de vid specificat, the lower chamber of the test is closed, the high pressure chamber (Camera superioară) is filled with a certain pressure test gas, and ensure that a constant pressure difference (reglabil) is formed on both sides of the sample; În acest fel, the gas will penetrate from the high pressure side to the low pressure side under the action of the pressure difference gradient. Through the monitoring and processing of the pressure inside the low pressure side, the barrier parameters of the tested samples can be obtained.
