Abstract

Piezo technology is used in a large number of sectors thanks to the possibility of switching between electrical energy and motion energy. In particular, Piezo technology provides an important advantage in pneumatic applications with its features such as low energy consumption, accuracy, quiet operation, compact structure, fast switching possibility, quiet operation and lightness. Directional control, proportional pressure control, proportional flow control, positioning, soft-stop and similar basic applications are being transformed into controlled and digitalized Pneumatic System applications. In this study, an experimental test device with a pneumatic cylinder working with piezo valves and position sensors was installed and motion control application was performed. In the experimental results of the application, the system characteristics can be observed graphically, and the results can be analyzed.

Experimental Analysis of Pneumatic Motion Control Application with Piezo Technology

Abstract

Piezo technology is used in a large number of sectors thanks to the possibility of switching between electrical energy and motion energy. In particular, Piezo technology provides an important advantage in pneumatic applications with its features such as low energy consumption, accuracy, quiet operation, compact structure, fast switching possibility, quiet operation and lightness. Directional control, proportional pressure control, proportional flow control, positioning, soft-stop and similar basic applications are being transformed into controlled and digitalized Pneumatic System applications. In this paper, piezovalves developed using piezoceramic material are compared with solenoid valves in pneumatic applications. The working methods and advantages of piezo technology in pneumatic applications such as pressure control, flow control, motion control are presented. The experimental test device with a pneumatic cylinder working with piezo valves and position sensors was installed and motion control application was performed. In the experimental results of the application, the system characteristics can be observed graphically and the results can be analyzed.
