滑片式压缩机卸荷过程的静态特性建模与仿真
Modeling and Simulation of Static Characteristics during Unloading of Vane Compressors
摘要
Abstract
In order to study static characteristics during unloading of vane compressors, flow models of fluid entering air intake and fluid entering unloading valve were built. It is found that the relation of dimensionless flow and pressure is parabolic and dimensionless flow decreases with the increasing of pressure by analysis of pressure and flow characteristics. Slope of pressure gain curve increases with ratio of outlet flow coefficient and inlet flow coefficient through research of pressure gain charac- teristics. At last,it is discovered that flow increases with displacement of sliding pole by means of displacement and flow curve. Static characteristics test of 22kW vane compressor verified the above conclusions. The research results provide important theoretical guidance for improvement of response speed and open-closing characteristics of unloading valve.关键词
