Abstract

The thermodynamic properties of compressible gases have on impact indicators of piston compressor. Informs about the results of computational studies cooled stage piston compressor the working on helium, air and methane. In order the correctly comparison the characteristics stage its main regime and geometrical parameters taken equal. This allowed reduce the number of variables in the during analysis of the characteristics of stages. For example, it is shown that in the intensity heat exchange the stage to impact convincing heat exchange surface  and conditional speed motion of the gas relative to the walls of the working chamber. Numerical experiments were conducted using the simulated application program «KOMDET-M». Investigations have established that the volume and mass productivity stage with changes the compressed gas do not remain constant indicating power stage and the temperature of injected gas increase with increase indicator exponent adiabatic compressed gas simultaneously this reduces the effectiveness of performance stage characterized by the specific indicator power.
