1, bubble method: first of all to be really detected pressure to Feiente gas booster pump booster to use to achieve the air tightness test pressure, after the decompression valve to use all kinds of pressure, pressure on really stringent will use high precision pressure gauge.
Accurate gas pressure through high pressure pipeline, valve, pressure gauge to be detected, the end of the above conditions to be tested into the water, there is no bubble leak. Advantages: it can be intuitively found that the leakage points, shortcomings: only suitable for water container detection. Bubbling air tightness detection equipment is divided into manual air tightness testing equipment (full manual control), PLC (air tightness testing equipment can be set holding pressure time, line pressure, qualified and unqualified alarm, a set in the future, you only need to connect the test piece good follow-up point switch line), computer leak detection equipment (this device PLC function has also detected print statements, the container segment pressure detection, real-time monitoring, automatic storage and other functions).
2, the pressure drop detection method: the air tight pressure drop detection method and the airtight bubble detection method are different. The difference is that the pressure drop detection method does not need to be placed in the water. The high-pressure gas is injected into the sealed container to be detected, and the end is observed if the pressure drops.
Advantages: no need to put in the water suitable for various containers for air tightness testing, the shortcomings: can not be observed directly to the leak point, the pressure drop is not obvious when the container is too large. The pressure drop air tightness detection equipment is also divided into manual air tightness detection equipment, PLC air tightness detection equipment and computer version air tightness detection equipment (function is the same as bubble detection device).
