Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber ring testing technology, specifically a rubber ring sealing performance testing device. Background Technology
[0002] Rubber rings, also known as sealing rings, are devices used to prevent liquid or gas leakage. They are typically made of elastic materials and serve a sealing function. The choice of material is crucial to their sealing performance and service life, as the material's properties directly affect the sealing ring's performance. Traditional rubber rings require sealing performance testing during use. However, traditional testing equipment uses relatively simple methods, which can affect the accuracy of the tests due to varying conditions, leading to unsatisfactory test results. Therefore, we propose a rubber ring sealing performance testing device. Utility Model Content
