COMPARATIVE EVALUATION OF METHODS FOR CALCULATING THE DYNAMICS OF SELF-ACTING VALVES IN RECIPROCATING COMPRESSOR UNITS

摘要

A comparative analysis of the influence of the law of motion of the plate of a self-acting valve on the calculation of efficiency indicators of the working process of a piston compressor stage, such as the temperature of the discharge gas, the flow rate and the indicated isothermal efficiency, is presented. Long-stroke, low-speed, and high-speed stages are considered. The conducted studies demonstrate the need to apply the methodology for calculating the dynamics of real valves having elastomeric elements in relation to the stages of low-speed long-stroke compressor units, as well as the relevance of additional studies to clarify the individual components of this method.
