Description
Technical Field
The utility model belongs to the technical field of filters, and particularly relates to a filter tightness micro-leakage detection device.
Background
At present, the tightness of a filter is detected mainly by a water bubble detection method by a detection means of tightness of the filter.
The water bubble detection method is to fill compressed gas with certain pressure into the tested product, then immerse the tested product into the liquid, and if the tested product has leakage, the continuous bubbles are formed in the liquid to float out.
The leak detection method has two problems:
1. false bubble interference; the surface and the structure of the tested product have trapped air positions, and the gas can randomly float out due to shaking circulation, so that the judgment on whether the tested product leaks or not is influenced, the result of whether the tested product leaks or not can not be obtained, the product can not be used, and only reworking or scrapping can be realized, so that waste is caused. Therefore, the leak detection mode has poor reliability and high inaccuracy.
2. Pollution of the tested products; after the tested product is immersed in the liquid, the liquid can be remained at the structural gap of the product, so that the rust-proof layer of the product is damaged, and the rust-proof service life of the product is shortened; in addition, the liquid is accumulated for a long time, so that microbial corrosion products are formed, and the functional failure of the products is caused.
