AI Technical Summary

⚠Technical Problem

Existing rubber gasket corrosion resistance testing devices cannot simulate the actual stress state of gaskets during actual use, and the testing methods are too simplistic, resulting in significant discrepancies between the test results and actual engineering conditions.

⚗Method used

A device for testing the corrosion resistance of rubber gaskets was designed. Through a motor-driven switching component and a pre-tightening component, the device simulates the stress and stress-corrosion synergy of the gasket under actual working conditions. By employing multi-path gas flow and rubbing shear stress simulation, the device enables multi-state testing of the rubber gasket.

🎯Benefits of technology

It enables the testing of the corrosion resistance of rubber gaskets under different stress conditions, and the test results are more realistic and reliable, which can accurately assess their performance degradation in actual working conditions.
