Experimental investigation of a temperature change inside pneumatic cylinder chambers

Abstract EN

The investigation of the existence of a temperature change with pressure inside the pneumatic cylinder chambers during the charging and discharging strokes in the pneumatic cylinder is experimentally demonstrated.

Three different variables (pressure, piston displacement and temperature) were measured in this work while operating with a servo pneumatic system and a discussion of the relationship between these variables was presented.

The cylinder used has a piston diameter of (0.05m), piston rod diameter (0.02m) and a stroke length of (0.2m).

The results show a temperature rise of 23 K above atmospheric temperature at chamber (1) while air compressing and a temperature drop of 17 K below atmospheric temperature at chamber (2) while air expansion and measures other temperature changes also
