Shenzhen HiraysasAir tightness testing equipmentR&D and manufacturing manufacturers, the products produced have been well applied in the market, such as automobilesCamera waterproof detection, engine seal detection,Cable IP65 IP67 waterproof detection, lamp seal inspection,Waterproof testing.Waterproof testing of electric toothbrushes and other places where waterproof testing, sealing testing, leakage testing, and IP waterproof level testing are required.

1. Characteristics of air tightness testing

It cannot accurately determine the leakage location, but it is convenient for automation, has short detection time, is stable and reliable, and is fast to test. The workpiece to be tested can be kept dry and will not cause secondary pollution of the product being tested. The amount of leakage can be quantitatively measured; the IP waterproof level can be obtained based on the amount of leakage.

The air tightness testing method is very suitable for mass testing on production lines and completely eliminates human factors.Quantitative measurement can be automated and the detection speed is fast, so it can be widely used.

two,Air tightness testingmethod

Air tightness testing includes direct pressure testing method, differential pressure method, flow leakage testing method, etc. When the internal volume of the parts to be tested is relatively small, the pressure testing method is more suitable.When the internal volume of the part is relatively large, you can consider choosing the flow-type detection method.The detection accuracy requirements are very high, and the differential pressure method is more suitable for complex shapes.

Block the opening of the product, fill the interior of the product with compressed air of a certain pressure, and use a tester to measure the pressure or flow rate inside the product. If the product leaks, the pressure will decrease or the flow rate will increase.Under the same conditions, when the measurement accuracy requirements of the parts are not high, you can consider choosing the absolute or relative pressure detection method; when the measurement accuracy requirements of the parts are high, the differential pressure detection method is more suitable.
