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.

准确得气体压力经过高压管路，截止阀，压力表进入被检测件，完结上述条件后把被检测件放入清水中，看有无冒泡走漏。长处：可以直观得发现走漏点，缺点：只合适不怕水容器检测。冒泡气密性检测设备分为手动气密性检测设备（全手动操控），PLC气密性检测设备（可设置保压时刻，上下线压力，合格和不合格报警，一次设定好今后，后续只需连接好检测件点下开关即行），电脑气密性检测设备（此设备PLC得功用都有还能打印检测陈述，容器分段压力检测，实时监控，自动存储等多种功用）。

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，压降检测法：气密性压降检测法和气密性冒泡检测法不同之处就在于压降检测法不必放到水中，是把高压气体注入被检测气密性容器内密封，经过看压力有无下降来完结。

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.

长处：不必放入水中合适各种容器得气密性检测，缺点：不能直观得观察到走漏点，容器过大时压降不明显。压降气密性检测设备相同分为手动气密性检测设备，PLC气密性检测设备，电脑版气密性检测设备（功用同冒泡检测设备相同）。

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).
