Multistage piston compressor units based on low-speed long-stroke stages are considered as a means of compressing gases to high pressures. A theoretical analysis of the influence of the choice of interstage pressures of compressed air on the efficiency of the operation of low-speed stages is presented. It is shown that the principle of distribution of interstage pressures in the compressor under consideration differs significantly from the generally accepted recommendations for high-speed compressors: for multistage reciprocating compressors based on low-speed long-stroke stages, the decisive factor is not the ratio between the discharge and suction pressures, but the magnitude of the difference between them.
