Development Trends of Airtightness Leak Detectors

The airtightness leak detector mainly uses purified and dried air as the working medium to test the sealing performance of a certain volume of test chamber. It can also be connected in series or in parallel for other tests. However, gas-liquid two-phase flow systems and gas-solid two-phase flow systems cannot be tested directly, otherwise it may lead to incorrect test results or irreparable damage to the instrument.

What factors can cause air leakage detectors to malfunction?

When performing leak tests, it is also important to carefully consider the timing during the production process. For component leak testing, each subcomponent should be pre-tested. If a leak is not discovered until after all assembly is complete, it will not only be difficult to locate the leak point, but will also require additional time and effort for disassembly and testing.

What is the IP67 waterproof rating?

IP67 indicates that without damaging the shell, 6 means the phone can completely protect its internal circuits from dust, and 7 means that when the phone is immersed in water to a depth of no more than 1m, the protection time of its internal parts shall not be less than 30 minutes

Let's discuss common testing methods for airtightness leak detectors.

The leak detector system of the airtight leak detector manufacturer is equipped with imported high-precision sensors, and the testing accuracy can reach 0.01pa. It is widely used in waterproof testing of small household appliances, airtightness testing of valves and pipe fittings, waterproof testing of communication base station equipment, airtightness testing of medical devices, wire sealing testing, quarantine of outdoor monitoring products, leak detection of aluminum alloy die-casting products, leak detection of welding products, and all products that require waterproof, dustproof and leak-proof functions.

Water pressure test method for leak detection

It is mainly used for sealing tests of valves and pipe fittings, leak tests of stainless steel welded products, and micro-leak tests of aluminum alloy die-casting products. The principle is similar to the pressure drop method, but this method is better. Inject gas at a certain pressure into the sealed workpiece cavity, and inject gas at the same pressure into the standard tank.

How to operate a plastic bottle sealing integrity tester

Plastic bottles are common containers in our daily lives, used for packaging food, chemical, and pharmaceutical products. Due to the specific nature of their use, it is necessary to ensure that the sealing performance of plastic bottles meets the standard requirements. Manufacturers must conduct comprehensive or sampling inspections of all plastic bottles using a plastic bottle sealing tester.

How to improve differential pressure airtightness detection technology

Differential pressure airtightness detection technology uses a comparison method. The workpiece to be tested and a leak-free standard part are placed in the same sealed container. The workpiece and the standard part are filled with the same pressure gas. After a period of time, the airtightness of the workpiece is measured by comparing the pressure difference between the two sealed containers.

Explanation of the airtightness tester detection method

Air tightness leak detection instruments can be used for pressure decay leak detection, vacuum decay leak detection, airflow testing, and other air tightness leak detection methods. It is a new type of non-destructive leak detection instrument. Air tightness testers are widely used in the air tightness leak detection of small household appliances, valve fittings, communication equipment, medical devices, wires, and security products. Leak detection methods for sealed instruments are mainly divided into direct pressure method and differential pressure method. Different products use different air tightness instrument leak detection methods.
