A study on miniature compressed air storage system using double-acting cylinder for portable device

Abstract

Nowadays, there are many research study on the pneumatic device on vehicles. There is some application using compressed air storage system to produce vehicle power. However, there are some troubles facing to produce compressed air for outdoor purpose, since most of the compressors are in large size which will cause limited working space. Also, most of the compressors are not portable and hand-carrying size. The project objectives to investigate the parameters of a miniature air compressor during the reciprocation process and to analyze the compressed air pressure of piston type double-acting cylinder for the miniature air compressor. The piston rod is connected to connecting rod and pedal, which the movement of the pedal will convert a kinetic energy to the piston and generate compressed air inside the storage tank. Synchronization of 5/3 Ways Directional Control Valves is the key of the system to ensure the flow of compressed air well-kept in the storage tank. The pressurized air is able to be used into kinetic movement by reciprocating piston. The experiment was carried out manually by hand to generate compressed air until 200kPa. The results of pressurized air of 500kPa into kinetic movement is shown.
