Design and Simulation of Constant Pressure Pneumatic Storage Device

In order to improve the energy efficiency of the pneumatic system, a constant pressure pneumatic gas storage device is proposed to replace the traditional fixed volume gas storage tank. First, the structural principle of the constant-pressure pneumatic gas storage device is illustrated. Then, a typical pneumatic circuit with the traditional fixed volume gas storage tank and the constant-pressure tank is modeled and simulated in AMESim, respectively. The different system working characteristics of the gas storage device are compared. The results show that the designed constant pressure gas storage device can achieve the constant pressure characteristics. Besides, it shows significant energy saving performance.
