Device for testing material aging of seal rings

Abstract

The invention discloses a device for testing material aging of seal rings. The device comprises a chamber, a water return groove, a steam generator and a water cycling system. A test box used for bearing test rubber samples is mounted in the chamber; the water return groove is formed in the chamber, used for discharging residual water at the bottom of the text box and communicated with the text box; the steam generator is arranged in the chamber and used for generating steam entering the test box and is communicated with the test box; the water cycling system is arranged in the chamber and communicated to the test box through the water return groove and the steam generator respectively. The device for testing material aging of the seal rings has advantages that by combination of factors including temperature and humidity, optimal seal ring material aging test effects can be achieved in a complicated environment; accurate prediction of service lives of the seal rings in practical operation environments can be realized, accuracy and precision in prediction are improved, and structural simplification and convenience in use are realized.

Description

technical field [0001] The invention relates to the field of mechanical devices, in particular to a device for testing the aging of sealing ring materials. Background technique [0002] Rubber sealing ring is a sealing tool widely used in hydraulic and pneumatic systems. The aging of the materials used will have a greater impact on its sealing effect. Therefore, the aging test of rubber sealing materials is of great importance for sealing rings. very important. [0003] In the prior art, the aging test method of the sealing ring material is mainly based on the accelerated aging test under the influence of single factor temperature. Although this method is relatively easy to operate and only needs to consider the temperature factor when estimating the life of the sealing ring, the disadvantages are also It is more obvious: due to the lack of consideration of humidity factors, the test effect of the aging of the sealing ring material cannot be optimal in the test environment ...
