How to use what kind of device to prepare gas and liquid under normal circumstances.Before the entire device is assembled, the air tightness of each device must be tested to ensure that the entire device is air tight and there is no leakage or leakage.How does gas leak or liquid leak? Let's not talk about anything else. First, if the leaked gas is dangerous to the human body and the leaked liquid is corrosive, then this device will definitely be a failure.Secondly, if there is leakage or leakage during the use of the device, there will be varying degrees of waste, and the leaked gas is likely to pollute the environment. The liquid will speed up the life of the consumed device and will also be attached to the device. No one wants to see the entire device dirty. Thirdly, if it is a device used in a laboratory, any leakage or leakage will lead to inaccurate data.What about the devices used in factories?If the gas or liquid installed is relatively rare, poor air tightness will cause waste.The air tightness of the fourth device is not good. If it is used in an environment with water, water may enter, which will shorten the life of the device.So whether in theory or in actual use, a large number of devices require air tightness testing?

installedAir tightness testingThere are mainly the following methods

The traditional method of soaking in water is to put the device in water and check whether bubbles come out. If there is any leakage or poor sealing, this method cannot detect the amount of leakage, is not accurate, and can easily cause secondary pollution. Moreover, some devices are also suitable for soaking in water, such as electronic devices. This is not possible, because electronic devices cannot come into contact with water. Water will conduct electricity, which will cause the energized parts of the electronic device to short-circuit and burn out.So is there a better method for testing the air tightness of a device than the water testing method?The answer is yes? Use gas seal detection method

gasSeal detectionThere are two main methods on the market. One is the air tightness testing method using helium. Helium generally requires special equipment to produce and generally needs to be recycled. The testing equipment requires a lot of components, which restricts the adoption rate. It is only used in special air tightness testing.One is to use the compressed air air tightness testing method. Since air is everywhere and does not need to be recycled, the components of the air tightness testing equipment are greatly reduced, and there is no pollution. As long as there is a press, there will be a continuous supply of clean gas for the air tightness testing equipment to use!

Therefore, gas air tightness testing equipment has been widely used. In recent years, a large number of air tightness testing equipment manufacturers have emerged. Among them, Shenzhen Hirays Automation Technology Co., Ltd. is the most representative in China. Over the years, Hiraysi has been committed to the research and development and production of air tightness testing equipment. After continuous efforts, it has successively launched various special air tightness testing equipment.Testing equipment, such as device air tightness testing, mobile phone waterproof tester, valve and pipe tightness tester, electronic device air tightness testing equipment, wire air tightness testing equipment, camera waterproof seal testing equipment, outdoor security waterproof testing equipment, LED waterproof testing equipment, medical equipment air tightness testing equipment, sports speaker waterproof testing system and a series of testing equipment.The accuracy can reach 0.1PA.It is enough to meet most air tightness testing requirements, and its technology has reached the international level.
