Abstract

The invention relates to rapid hydrogen charging complete equipment based on a gas driving and pressure enhancing technology. The equipment comprises a pregaining hydrogen storage tank, a gas driving and pressure enhancing pump, a detected hydrogen storage tank, a first pressure sensor, a PLC controller, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve,a fourth electromagnetic valve, a first gas control valve controlled by the first electromagnetic valve, a second gas control valve controlled by the second electromagnetic valve, a third gas controlvalve controlled by the third electromagnetic valve, a fourth gas control valve controlled by the fourth electromagnetic valve and a fifth electromagnetic valve. A gas inlet of the gas driving and pressure enhancing pump is connected with corresponding gas outlet pipelines of the detected hydrogen storage tank and the pregaining hydrogen storage tank. A gas outlet of the gas driving and pressure enhancing pump is connected with corresponding gas inlet pipelines of the detected hydrogen storage tank and the pregaining hydrogen storage tank. The first pressure sensor detects the pressure of thedetected hydrogen storage tank, and outputs the pressure signal to the PLC controller, the PLC controller controls opening and closing of the gas driving and pressure enhancing pump through the fifthelectromagnetic valve, and controls the first gas control valve, the second gas control valve, the third gas control valve and the fourth gas control valve through the corresponding first electromagnetic valve, the corresponding second electromagnetic valve, the corresponding third electromagnetic valve and the corresponding fourth electromagnetic valve to open or close the gas path. According tothe present invention, the sufficient and real hydrogen storage and rapid hydrogen charging and discharging tests are provided for the high-pressure hydrogen storage tank provided by the present invention to obtain the leakage prevention ability of the high-pressure hydrogen storage tank during bearing repeatedly hydrogen charging and discharging, the equipment provided by the present invention has advantages of rapid speed of the hydrogen charging and discharging, high performance and reliability.

Description
