Description

technical field [0001] The invention relates to the technical field of hydraulic leakage resistance testing, in particular to a hydraulic leakage resistance testing system. Background technique [0002] According to the provisions of GB / T15812.1 "Non-intravascular Catheter Part 1: General Performance Test Methods", the hydraulic leakage resistance test of catheter products requires the use of a test system that can apply water pressure, which is specified in the standard Requirements include a pressurization system and a measuring instrument. The existing water pressure resistance test system adopts manual pressure application and has no timing system, so it has defects such as low test efficiency and low test accuracy. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a hydraulic leakage resistance test system, which can solve the above-mentioned defects existing in the existing hydraulic pressure resistance tes...
