A high-pressure dynamic sealing test device for rubber rings under extreme conditions

Abstract

The invention provides a rubber ring high pressure dynamic sealing test device under extreme conditions, and belongs to the technical field of aerospace and mechanical engineering. The rubber ring high pressure dynamic sealing test device under the extreme conditions comprises a reciprocating movement test machine, a high pressure inflator, a gas flowmeter, a heating device, a refrigeration device and a test implementation body. Frictional force, displacement, temperature and gas leakage can be synchronously measured under sealed high pressure dynamic reciprocating movement of a rubber ring in the extreme conditions. The effects and the benefits of the rubber ring high pressure dynamic sealing test device under the extreme conditions are that dynamic sealing performance testing of the rubber ring under different extreme conditions (high pressure, high temperature and low temperature) can be realized. The device has the characteristics of being easy and convenient to assemble and flexible and easy to use.

[0002] The rubber ring seal has a simple structure and good sealing performance. It has important applications in the fields of aerospace and mechanical engineering. It can be used as a static seal or a dynamic seal. Complex load conditions and pressure conditions, therefore, it is very important to study the sealing performance of rubber ring seals under high pressure, high temperature, low temperature, and reciprocating motion conditions, especially for simultaneous measurement of friction and leakage under extreme conditions , is of great significance to the design of high-performance rubber ring seals. At present, there is a lack of such a test device, which can directly measure the force-displacement curve and leakage of rubber ring seals directly under the reciprocating motion conditions of high temperature and high pressure or low temperature and high pressure. The present invention aims to solve such related problems
