Abstract

The invention discloses a gas charging and discharging circulation test system for a high-pressure hydrogen storage bottle. The system comprises a hydrogen source (1), a compression device (2), a high-pressure hydrogen storage device (3), a conveying circuit (4), a hydrogen flow regulating device (5), a hydrogen temperature adjustment device (6), an ambient temperature and humidity adjustment device (7), a hydrogen recovery device (9), a venting device (10) and a measurement control unit (11); a test equipment system in the performance test of a type B gas cylinder required for a hydrogen pressure fatigue test at normal temperature and extreme temperature with hydrogen as a medium and a pressure permeation / leakage test at an extreme temperature is completed. The system has reasonable design, strong operability and good use effect, can perform a smooth charging and discharging process, and can complete partial performance tests of the high-pressure hydrogen storage bottle.

Description

technical field [0001] The invention relates to the technical field of type testing of high-pressure hydrogen storage cylinders, in particular to hydrogen pressure fatigue tests at room temperature and extreme temperatures and air pressure permeation / leakage tests at extreme temperatures for 70MPa high-pressure hydrogen storage cylinders. The inflation and deflation cycle test device carried out. It can be used for compressed hydrogen aluminum liner carbon fiber fully wound gas cylinders for vehicles. Background technique [0002] "GTR13: Global technical regulation on hydrogen for fuel cellvehicles" (Global Technical Regulations on Hydrogen Fuel Cell Vehicles) is a criterion for evaluating the performance of various parts of hydrogen fuel cell vehicles around the world, and each signatory country must promote it domestically. The National Gas Cylinder Standardization Technical Committee, on the basis of summarizing the design, manufacture, use experience and research resul...
