This paper reviews the composed principle and key technologies of gas-liquid pressurization system. In order to improve the dynarnies performance of the gas-liquid pressurization system, the mathematical model of sole- noid valve is established. And furthermore , performance of solenoid valve affected by some key parameters such as the gas length, the drive current, the turn ratio, the air pressure value and so on are analyzed by means of the sim- ulation software MATLAB/Simulink. Improved experimental system on key parts of the gas-liquid pressurization system is carried out. The results show the feasibility of the optimization through the experimental test.
