Problems solved by technology

[0002] In the field of engineering design, according to the needs of tasks and functions, it is often necessary to design a certain form of rotating mechanism to adjust the movement flexibly and ensure the connection at both ends and the sealing during rotation. However, the traditional rotating mechanism often has a relatively large rotation angle. Small and regular in shape, it cannot be well applied in the limited installation area, and its mechanism design cannot be transplanted. Therefore, it is necessary to design a new form of folding and rotating mechanism to meet the needs of specific functions, but in the application In the past, it was often necessary to verify and evaluate the folding and rotating sealing of the mechanism during its service life

Abstract

The invention belongs to the technical field of mechanisms, and relates to a dynamic sealing life testing verifying method of a folding rotating mechanism of an oil-gas channel. The dynamic sealing life testing verifying method comprises the following steps: creating a life verifying testing environment for a folding rotating mechanism according to the service condition of the folding rotating mechanism of the oil-gas channel; performing the sealing lie testing verifying for the folding rotating mechanism. With the adoption of the method, the folding and unfolding following functions can be realized; in addition, the sealing performance meets the system requirement during continuous folding and unfolding under high-temperature, room-temperature and low-temperature conditions; the method is high in generality and can be popularized to different fields needing the testing verifying of the dynamic sealing life of foldable mechanisms.

Description

technical field [0001] The invention belongs to the field of mechanical design, and relates to a method for verifying the service life of a dynamic seal of an oil-gas path folding rotating mechanism. Background technique [0002] In the field of engineering design, according to the needs of tasks and functions, it is often necessary to design a certain form of rotating mechanism to adjust the movement flexibly and ensure the connection at both ends and the sealing during rotation. However, the traditional rotating mechanism often has a relatively large rotation angle.
