Leakage Paths of two type of Meshing Pairs in Single Screw Compressors

摘要

Straight line and column envelope type meshing pairs are two important meshing pairs in single screw compressors, while straight line envelope meshing pair is actualized but the other is still fail to meet industrial applications. The column envelope meshing pair of single screw compressors is proposed to improve the operating life of the compressor for poor wear resistance of existing straight line envelope meshing pair. To accelerate the industrial application of the new type compressor, leakage paths of two meshing pairs are analyzed and compared in this paper. Results shows that leakage paths of two type meshing pairs are rather different, this situation may one causation that column envelope meshing pair is remained in theory.
