High-pressure sealing ring testing device and testing method

Abstract

The invention relates to a high-pressure sealing ring testing device and a testing method. The high-pressure sealing ring testing device comprises a pressure chamber, wherein the pressure chamber comprises a barrel and a test piece mounting structure; a medium channel communicated with the interior of the barrel is formed in one end of the barrel; the test piece mounting structure comprises an outer plug, an inner plug and an end cover; the outer plug is in threaded connection with the other end of the barrel; the inner plug is mounted in a circular hole of the outer plug; an annular groove for mounting a test piece is formed in the outer wall of the inner plug; the end cover axially props against the inner plug and the outer plug from the outer end; the end cover is in threaded connectionwith the outer plug. The high-pressure sealing ring testing device can be applied to testing tests of sealing rings with different wire diameters and different thicknesses, different sealing groove shapes and the like, and is simple to assemble and convenient to use; according to the method, the performance of the sealing rings is tested at different temperatures and different pressures, the performance evaluation of the sealing rings is perfect and comprehensive, and the testing result is reliable.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a testing device and a testing method for a high-pressure sealing ring. Background technique [0002] Sealing rings are common seals. A wide variety of seals are used in fidelity corers. The performance of the sealing ring directly affects the pressure-holding performance of the fidelity chamber. [0003] Existing sealing ring test devices are usually aimed at checking the sealing performance under normal pressure. Fidelity corers usually need high-pressure storage of rock cores. At this time, the sealing ring is in a high-pressure environment, and even qualified products under normal pressure may produce leakage. [0004] In addition, most of the existing sealing ring testing devices are designed to test sealing rings of the same size. However, for fidelity core removers involving multiple sealing rings of different sizes, multiple testing devices are required, and ...
