Abstract

Ал analytical expression was deduced for a conditional clearance determining the amount of leakage through piston sealing of the compressor, which allows to take into account the wear of rings during operation. An example is given for the calculation of leakage in I and II compressor stages of expander-compressor unit DKA 20-10/1C taking into account the wear of rings according to the offered technique. The technique allows to predict periodicity of rings change knowing the design and operating conditions of the stage.
