Determination of strength characteristics of elements of long-stroke piston compressor

Abstract

The work analyzes the strength calculation of the long rod of the piston of the long-stroke piston compressor designed to obtain excess gas pressure. The pressure increase in one compressor stage can increase to 120 times the initial gas pressure. Criteria of strength calculation of piston rod are defined at which it is necessary to use either method of rod calculation for strength or model of rod calculation for stability. Conclusions have been drawn and practical recommendations are given that can be used in the design of compressor stages.
