Description

TECHNICAL FIELD

[0001] The utility model relates to material performance detection technical field especially relates to a combination gasket service life testing arrangement. BACKGROUND

[0002] The combination gasket service life testing arrangement is simply a machine specially torturing gasket to see how long it can be used before breaking down. For example, the gasket in the automobile engine has to bear high temperature, high pressure and oil corrosion, and the machine simulates these harsh environments to force the gasket to retire early and measure its life limit.

[0003] In the common prior art testing equipment, the observation glass serves as an important window connecting the operator and the internal testing condition of the equipment, and its setting purpose is very clear, that is, to enable the operator to observe the state of the combination gasket in the testing equipment body 1 in real time and intuitively without interfering with the testing process. However, a significant problem is exposed in actual application. Since the testing environment is often complex, especially when testing the service life of the combination gasket, the testing process involves multiple working condition simulations such as high pressure and vibration, which easily leads to splashing of sundries. Once these sundries adhere to the surface of the observation glass, they will seriously affect the observation effect. The operator may not be able to clearly see whether the gasket has deformed, leaked or other key signs, and thus cannot accurately judge the testing progress and results. More importantly, most existing testing equipment is only equipped with an observation glass without a corresponding cleaning component. This makes the operator only be able to clean the observation glass by manual wiping once it is contaminated, which not only needs to interrupt the testing process and open the testing equipment, but also may introduce new impurities due to improper operation or damage the precise testing environment inside the equipment, affecting the accuracy and reliability of the testing data.
