Calculation of Rational Values of Discharge Pressures in the Compressor and Pump Sections of a Crossheadless Reciprocating Hybrid Power Machine

Resumo

A procedure for calculating rational values of the nominal discharge pressures in the compressor and pump sections of a crossheadless hybrid power machine based on equality of volumes of mass flowing from the pump section to the compressor section and back in the course of the cycle is proposed. From a numerical experiment we are able to evaluate the influence of the main design and operating parameters on the ratio of the nominal discharge pressures in the compressor and pump sections. Based on the analysis, the principal methods of equalizing the nominal discharge pressures in the compressor and pump sections are determined.
