Airtightness TesterIt is an important piece of equipment in the manufacturing industry that helps companies ensure the quality and safety of their products. It isInstruments and equipment used to detect whether there is leakage of various seals, containers, pipelines, etc., by filling the product under test with gas or liquid and judging the sealing performance by detecting the amount of leakage.It is also called airtightness test equipment, waterproof test machine, airtightness leak tester, sealing tester.
Air tightness tester is widely used in industrial manufacturing, including new energy, household appliances, auto parts, consumer electronics, medical devices, security lighting, valves and pipes, wire connectors and other industries.
Ⅰ.The purpose of the airtightness test is to
- Test whether the airtight design of the product is reasonable.
- Check that the product's interfaces and joints are completely airtight.
- Evaluate the ability of the product to meet the corresponding IP protection rating.
- Ensure airtightness and protection of the product during use.
Ⅱ.The main types of test methods are as follows
- Differential pressure method:The product to be measured is placed in an airtight container, filled with gas or liquid, and the difference in pressure between the inside and outside of the container is detected; the differential pressure method is also called the pressure drop method.
- Vacuum attenuation method:The product under test is placed in a vacuum environment to detect the amount of gas or liquid leakage inside the product under test, the vacuum attenuation method is also called the negative pressure method.
- Helium leak detection method:Helium is injected into the product under test and a helium leak detector is used to detect the amount of helium leakage inside the product under test, also known as helium leak detection.
III.Gas Tightness Tester Test Media
There are two main types of test media for the gas tightness tester: gas and liquid.
Gas test media have the advantage of higher sensitivity, but require the use of auxiliary equipment such as vacuum pumps, which are more costly.
Commonly used gaseous test media include air, nitrogen, helium, and so on. Compressed air is one of the most commonly used gas test media and has the advantage of being easy to obtain and inexpensive. Nitrogen is an inert gas with good permeability and can be used to detect small leaks. Helium is a light gas with high permeability and can be used to detect objects with good sealing properties.

Liquid test media have the advantage of being easily accessible and inexpensive, but have poor sensitivity.
Liquid test media are commonly used, such as water, oil, solvents and so on. Water is a commonly used liquid test medium, its advantage is easy to obtain, low cost. Oil has good adhesion, can be used to detect irregular objects on the sealing surface. Solvent has good solubility, can be used to detect the sealing surface of the presence of dirt or debris objects.
