along withAir tightness testing equipmentdevelopment, the acceleration of the industrialization process of air tightness testing, and the impact on productsSealing testThe quality requirements are getting higher and higher.Many products have strict requirements for sealing. To detect the sealing of products, you need to useAir tightness tester, choosing the correct air tightness tester will better guarantee product quality and greatly improve production efficiency.What types of air tightness testers are there now? Let’s introduce them to you below.

1. Use differential pressure algorithm to develop air tightness detector.

Air tightness detector also known asAir tightness testing equipment, leak detector, air tightness instrument, etc.There are many names, mainly used for product sealing testing, waterproof testing, air tightness testing, ipX waterproof testing level detection and identification

Compared with traditional leak detectors, the differential pressure algorithm air tightness detector saves labor costs and reduces detection links. Compared with the direct pressure type, the accuracy of the direct pressure type is relatively low.The differential pressure type mainly uses a high-sensitivity differential pressure sensor, which has higher testing accuracy and has the advantages of fast inflation, good sealing, no heat, and long service life.Differential pressure air tightness testing equipment has made positive contributions to the fields of automobiles, aviation, electronics, audio equipment and other fields, while also providing them with a wider space for development.

2. Micro-flow typeAir tightness testing equipment

The micro-flow air tightness detector mainly checks whether the workpiece is qualified by detecting the air flow per unit time of the tested part and comparing it with the standard part.This leak detector uses a micro-flow sensor to directly read the air flow passing through the sensor, and the instrument directly displays the leakage rate of the component being tested.The test results have nothing to do with the volume of the tested piece, the test process is simple and fast, and the test results are true and accurate.

Micro-flow air tightness testers are also widely used, mainly in motor vehicle parts: carburetors, motorcycle engines, fuel inlet needle valves, fuel tank switches; gas appliances: gas stoves, gas meter valves, gas ovens, plug valves, gas water heaters; electrical products: sealed relays, sealed motors, submersible pumps, solenoid valves; others: medical equipment, watches, underwater cameras, etc.

3. Pressure drop typeAir tightness detector

Pressure drop typeAir tightness detectorAs the name suggests: the principle is to inflate or evacuate the tested part, detect the pressure drop value within a certain period of time, and then accurately calculate a certain pressure and the air leakage value within a certain period of time. Based on the air leakage value, it is possible to determine the sealing, airtightness, and waterproofness of the product. This is an airtightness testing equipment that is currently on the market.It is suitable for full inspection on production lines and has the characteristics of fast speed, good stability and low cost.

Through the above analysis, do you understand the types of air tightness testing equipment? When choosing an air tightness testing instrument, you can use this as a basis to select the instrument that is most suitable for your company's products. In addition, you should also consider factors such as test pressure.
