Micro leak leak tester is a precision instrument used to test the sealing performance of products, which is used in food, medicine, chemical and other industries. The structure of the test chamber is one of the key factors affecting the accuracy of the test results. This article will explain the test chamber structure of the leak tester.
The structure of the test chamber usually consists of an upper chamber, a lower chamber and connecting parts. The upper and lower chambers are used to place the sample to be measured and the reference sample, respectively, and the connecting parts are used to tightly connect the upper and lower chambers together to form an enclosed test space. This structural design ensures that the sample is completely isolated from the external environment during the test process, avoiding the influence of external gases or liquids on the test results.
The chamber material is usually made of stainless steel or other corrosion-resistant materials. This is because during the test, some corrosive substances may be involved, such as strong acids, strong bases, etc. Test chambers made of corrosion-resistant materials can effectively extend the life of the instrument and reduce maintenance costs.
In addition, the inner surface of the chamber often requires special treatment to improve its sealing performance. Common treatment methods include polishing, plating, etc. The polishing treatment can make the surface smoothness of the cavity reach a certain standard, which is conducive to improving the sealing performanceThe coating treatment can form a protective film on the inner surface of the cavity to prevent the erosion of corrosive substances on the cavity, and at the same time, it can also further improve the sealing performance.
In practice, the structure of the micro-leak leak tester test chamber also needs to be customized according to the specific testing needs. For example, for samples that need to be tested in different shapes and sizes, they can be designed with adjustable cavity structures;For samples that need to be tested under different pressure conditions, it can be designed as a cavity structure with pressure adjustment function, etc. These customized designs can meet the testing needs of different industries and fields, and increase the flexibility of the use of test instruments.
The cleaning and maintenance of the test chamber of the micro-leak leak tester is also an important factor affecting the accuracy of the test results. Before and after each test, the test chamber needs to be thoroughly cleaned to eliminate the influence of residues on the test results. At the same time, the test chamber needs to be regularly inspected and maintained to ensure that its sealing performance is always in good condition.
The micro-leak leak tester test cavity structure is one of the key factors affecting the accuracy of the test results. Through the optimized design of the test chamber structure, the performance and service life of the test instrument can be improved, and more accurate and reliable sealing performance testing services can be provided for various industries.
