Research on a new energy-saving and higher efficiency booster

In this paper, a new kind of booster, expansion energy used booster (EEU booster), is proposed, which makes use of the expansion power of the compressed air in the driving chambers. Through analysis of the boosters, a mathematical model of the working processes is set up. The motion characteristics of the piston, the variations of the pressure of the boosting chambers and the driving chambers, the characteristics of the output flow of the boosters were obtained. Moreover, a new energy consumption evaluation criterion of pneumatic system, air power, is briefly introduced. Simulation and experimental results of the boosters were conducted and the output air power and efficiency characteristics of the boosters were obtained. The simulation results have a good consistency with the experimental results.
