Abstract
A pressure-adjustable auxiliary control system for high-pressure gas sealing detection includes: a high-pressure chamber environment monitoring unit configured to construct high-pressure test gas sealing environment and to test sealing performance of a sealing member; a first gas pipeline divided into two branches, of which one branch is connected to the high-pressure chamber environment monitoring unit as a first gas replacement path; a second gas pipeline which is connected to a test gas pressurization path together with the other branch of the first gas pipeline, where a first booster pump processing unit and a second booster pump processing unit are sequentially arranged in the test gas pressurization path for pressurizing the test gas, and are connected to the high-pressure chamber environment monitoring unit; a system air control module configured for control of respective air control valves; and a booster pump air control module and a driving air source preprocessing unit.
