Experimental System Research on Energy-saving Method of Bridge Pneumatic Circuit

For the purpose of controlling the bridge pneumatic circuit intake and exhaust independently, which consists of several on-off valves, improving the utilization of compressed air and the stability of piston operation. An experimental system was produced by LabVIEW,which is designed for realizing energy-saving and motion control of bridge pneumatic circuit.Through simulation and experiment, data processing and analysis, the developed experimental system has multiple functions and reliable behavior. It is found that the experimental system can complete the measurement and control function according to the timing and quantitative intake and exhaust requirements, and the detected data is accurate and effective. The results show that the experimental system can also used for theoretical calculation results calibration and energy-saving effect evaluation of bridge pneumatic circuit energy-saving method.
