Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] The rubber ring high-pressure dynamic sealing test device is composed of a reciprocating motion testing machine, a high-pressure inflator, a gas flow meter, an upper fixing device, a lower fixing device and the main part of the test implementation; the reciprocating motion testing machine can Generates reciprocating motion, and can record the force and displacement curves in the cycle in real time, so as to realize the measurement of force and displacement curves under dynamic conditions; the upper fixing device and the lower fixing device fix the main body of the test; the reciprocating motion test drives the reciprocating movement rod 1 reciprocate up and down inside the inner lining 22, and record the displacement of the reciprocating rod 1 relative to the inner lining 22, and the force when the reciprocating rod 1 and the inner wall of the inner lining 22 sli...

Abstract

The invention provides a high-pressure dynamic sealing testing device for a rubber ring, and belongs to the technical field of aerospace and mechanical engineering. The device comprises a reciprocating moving testing machine, a high pressure aerator, a gas flow meter and a test implementing body; the reciprocating moving testing machine moves by a reciprocating manner to enable the frictional movement between a sealing rubber ring on a connecting rod in the test implementing body and a replaceable lining testing material, and the reciprocating moving testing machine is able to synchronously measure the force and displacement; the gas leakage quantity can be synchronously measured through a designed pipeline system. The device has the effect and benefit that the high pressure dynamic sealing of the rubber ring can be tested under different design parameters; the device has the characteristics of being simple and convenient to assemble, flexible and easy to be used.

Description

technical field [0001] The invention belongs to the fields of aerospace technology and mechanical engineering, and in particular relates to a rubber ring high-pressure dynamic sealing test device. Background technique [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 and reciprocating motion conditions, especially for the simultaneous measurement of friction and leakage, and for high-performance rubber ring seals The design of is of great significance, and there is a lack of such a test device at present. Contents of the invention [0003] In order to solve the above problems, the present invention provides a rubber ring high-pressure dynamic sealing tes...
