An Experimental Study of a Crossheadless Piston Hybrid Power Positive Displacement Machine with Intensive Cooling of the Compressed Gas

Piston hybrid power machines combining the functions of a compressor and a pump in one unit have become widespread, with a new class of machines that do not have a crosshead currently under development. A prototype of such a machine was designed and manufactured based on the new concept of a crossheadless piston hybrid power machine. A plan for conducting a series of experimental studies was developed. The experimental studies confirmed the feasibility of the prototype in the entire range of independent operating parameters (discharge pressure in the compressor section, discharge pressure in the pump section, the number of revolutions of the crankshaft). The effect of operating parameters on the instantaneous and integral characteristics of the compressor and the pump sections of the crossheadless piston hybrid power machine was also assessed through the experimental studies.
