The airtightness testing of products without gas filling ports mainly involves testing the sealing performance of the products to ensure that they will not allow liquids or gases to penetrate or overflow, which is crucial for the quality and safety of the products. The testing process usually involves making a sealing fixture that matches the shape of the product, fixing the product in the fixture, and then using an air tightness testing instrument for testing. The principle of testing is based on the quantitative method (volumetric method), which involves filling a certain amount of dry, clean air, nitrogen or other inert gas into the sealed chamber of the fixture, and then observing the pressure changes inside the chamber to determine the sealing performance of the product.
If the product has good sealing, the air pressure inside the cavity will remain stable. If there is a leakage in the product, the air pressure inside the chamber will decrease. The high-precision pressure sensor of the airtightness detection instrument can detect this change and calculate the leakage value of the product based on the leakage rate. By comparing the leakage value with the set upper and lower limits of leakage, it is possible to determine whether the product is qualified. This detection method is particularly important for products without filling ports, as it can effectively test the sealing performance of the product, ensuring that it maintains the integrity and functionality of its internal structure under various usage conditions.
Airtightness testing is not limited to a certain type of product, but is widely used in various fields, including but not limited to automotive parts, medical equipment, aviation electronic equipment, etc., to ensure that these products can maintain good sealing performance in various usage environments.
