Talking about the current situation tightness testing technology at home and abroad

Currently, air tightness test equipment technology has been widely used at home and abroad to. Let Xiaobian come for you to explain tightness testing technology in the status quo at home and abroad, I hope for your help.
Currently popular tightness test method is to use the gas flow equation for testing. First measuring the amount of leakage associated with some parameters, such as pressure, pressure, the elastic wave, and then these relationships through a certain amount of correlation to the corresponding leakage. This detection method influenced by subjective factors is relatively small, high precision, and easy to implement automatic control, automatic alarm, greatly improving the detection efficiency. Depending on the measured parameters, according to the gas flow formulas leak detection method was divided differential pressure method, direct pressure, vacuum law, traffic law. Which measured parameter selection, have a direct impact on the leak detection accuracy. Direct pressure detection accuracy is low, the price is cheap. The high differential pressure and flow-type detection accuracy, the price is relatively higher. Should be based on characteristics of different parts, selecting appropriate leak detection equipment, and strive to economically rational, precise and effective.
Based on the above basic principles, many domestic and foreign manufacturers have developed a tightness tester, relatively well-known French ATEQ company, American USON company, Japan's COSMOS Corporation. The company is a pioneer in the world of manufacturing ATEQ tightness test equipment, and its product applications involving automobiles, pharmaceuticals, household appliances, casting, packaging, valves, gas, electronics, construction, aviation and other fields. USON company also produces various types of leak detector, its 4000 series offers a variety of detection modes, taking into account the performance of the leak, leakage, and provides for the practical application of volume and size of the leakage of different analytes the appropriate product. COSMOS company mainly produces special chemical gas leak detection equipment.
