Abstract:
The motion frequency is an important performance parameter of pneumo-pump. When the structure of the pneumo-pump is fixed, its frequency determines the flow rate of propellant and has a great influence on the outlet pressure. Therefore, the research of the operating frequency contributes to selecting a rational frequency parameter and matching the structural parameter and performance parameter of pneumo-pump. In order to explore the influences of gas properties on pneumo-pump performance, a mathematical model was set up and the working process of hydraulic pistons was simulated with AMESim. A comparison between simulation results and test data was made. The comparison results show that they are in good agreement.
