High-pressure hydrogen diaphragm compressor testing device for hydrogen refueling station and testing method of high-pressure hydrogen diaphragm compressor testing device

The invention discloses a high-pressure hydrogen diaphragm compressor test device for a hydrogen refueling station and a test method thereof, and the test device comprises a test foundation platform, a high-pressure gas supply circulation system, a low-pressure gas supply system, a cooling system, a closed loop adjusting system and a control system. The performance test of the high-pressure hydrogen diaphragm compressor is completed by adjusting the gas supply pressure of the gas pressurization system and a corresponding adjusting valve to simulate the operation conditions of the high-pressure hydrogen diaphragm compressor with the pressure of 45 MPa and 87.5 MPa. According to the test device and method provided by the invention, a simple, convenient and feasible operation device and method are provided for the performance test of the skid-mounted hydrogen diaphragm compressor, and the difficulty and cost of the performance test of the skid-mounted hydrogen diaphragm compressor are greatly reduced. 本发明公开了一种加氢
