Performance analysis of reed valve of rolling piston compressor based on fluid-structure interaction

Abstract

Abstract To analyze the influence of different thickness reed valves on the exhaust pressure pulsation, a two-way fluid-structure interaction model of the reed valve of the rolling piston compressor is established in this paper. Based on the results of the two-way fluid-structure coupling analysis, the deformation displacement and the influence on the pressure pulsation of the rolling piston compressor in a cycle under different reed valve thicknesses are compared. The analysis results show that under specific working conditions, with the increase of the thickness of the reed valve, the maximum deformation displacement decreases, the peak value of the exhaust pressure pulsation decreases, and there will be a phenomenon of early closing. The overall analysis obtains a better valve thickness. The research results have certain guiding significance for optimizing the structure of the reed valve and the comprehensive performance optimization of the rolling piston compressor.
