In the field of industrial production and quality inspection, the airtightness tester is a key equipment, but many people are not completely clear about what it can measure. Today, we will introduce the measurement scope of the airtightness tester.

1、 Gas leakage detection

1. Measurement of minor leaks

One of the core functions of the airtightness detector is to detect small gas leaks. Whether it is a miniature sealed chamber in electronic devices or a tiny air path in automotive components, they can all play a role. Through high-precision sensors and precise measurement algorithms, gas leaks with flow rates of several cubic centimeters or even smaller per second can be detected.

2. Macro leakage detection

For larger leakage situations, such as obvious leaks in pipeline systems or sealing issues in large containers, airtightness detectors can also quickly and accurately detect them.

2、 Sealing performance evaluation

1. Overall sealing of the product

For various sealing products, such as sealing gaskets, sealing gaskets, etc., the airtightness tester can evaluate their overall sealing performance. In the field of medical devices, products such as syringes and infusion bags that require good sealing can ensure that there will be no liquid leakage or gas ingress during use through airtightness testing. Place the product in a testing environment, fill it with a certain pressure of gas inside or outside, and judge the sealing effect by observing the pressure changes, thereby ensuring product quality and safe use.

2. Sealed connection between components

In complex mechanical structures, sealed connections between different components are crucial. For example, the sealing between the cylinder block and cylinder head of an engine, and the sealing between the blades and hub of an aircraft engine. The airtightness detector can detect the sealing of these connection parts and determine whether there is a gas leakage channel. This type of testing helps to improve the overall performance and reliability of the machinery, avoiding problems such as power loss and overheating caused by poor sealing.

3、 Material permeability test

1. Testing of porous materials

For some materials with porous structures, such as ceramics, certain polymer materials, etc., an air tightness detector can measure their air permeability. These materials have a wide range of applications in filtration, separation, and other fields, and their breathability directly affects their effectiveness. By injecting gas into one side of the material and detecting the passage of gas on the other side, parameters such as the material's permeability can be obtained, providing data support for material research and quality control.

2. Evaluation of New Materials

With the development of technology, new materials are constantly emerging. The airtightness performance of these materials needs to be accurately evaluated, and airtightness testers can provide effective measurement methods for them. For example, the application of new composite materials in the aerospace field, the testing of their airtightness performance can ensure their stability in extreme environments and ensure flight safety.

4、 Vacuum system sealing test

1. Vacuum equipment leakage inspection

The sealing of vacuum systems is crucial in fields such as semiconductor manufacturing and vacuum coating. The airtightness detector can detect small leaks in the vacuum system, ensuring that the system can achieve and maintain the required vacuum level. Even extremely small leaks can cause damage to the vacuum environment, affecting production processes and product quality. Through testing, leakage points can be detected and repaired in a timely manner to ensure the normal operation of vacuum equipment.

2. Vacuum packaging sealing

Vacuum packaging is widely used in industries such as food and electronics. The airtightness tester can check the sealing of vacuum packaging bags to prevent air from entering and causing food spoilage or oxidation of electronic components. It can quickly determine whether there is a leak in the packaging bag, ensuring the shelf life and performance of the product.

The measurement range of the airtightness tester is wide, covering multiple aspects such as detecting small leaks, evaluating material permeability, analyzing product sealing performance, and checking vacuum system sealing performance. It plays an indispensable role in many industries, ensuring product quality, improving production safety, and promoting technological development.
