Influence of the constructive parameters for long stroke piston unit on a stressed deformed cylinder state

This article assesses the influence of the long stroke piston unit design parameters for the stress-strain state of the cylinder slow-speed stage. The stress-strain state estimation for the piston compressor cylinder slow-speed stage with a cylinder diameter equal to and more than 50 mm, show a significant increase in gaps and leaks in the cylinder-piston pair is observed, as well as an increase in equivalent stresses in the cylinder walls to the value of the yield strength of the wall cylinder material. The analysis allows for optimal engineering of the piston compressor cylinder slow-speed stage for the most promising designs.
