Experimental Model for Energy Efficiency Examination of Pneumatic System

Vladislav Blagojević, Miodrag Stojiljković, and Vlastimir Nikolić

Abstract: In pneumatic systems, which represent large energy consumers, energy saving is very important. Mostly, the costs of the electric power used for feeding the compressors in the production of compressed air amount to around 20\% of the overall costs of electrical power for some factory. In order to examine energy efficiency of conventional pneumatic system as well as servo system, no matter on actuator type, in this paper the new experimental model for energy efficiency examination is proposed. It consists of two important parts, such as electric and pneumatic part. The conducted experiments have demonstrated that this new experimental model provides satisfactory results of actuator positioning and energy efficiency as well.

Keywords: Experimental model, amplifier, energy efficiency, positioning.
