Experimental Evaluation of the Efficiency of Long-Stroke, Low-Speed Reciprocating Compressor Stages in Compression of Different Gases

Abstract

Results of comparative experimental tests of a stage of a long-stroke, low-speed reciprocating compressor with compression of air, helium and carbon dioxide in a single-stage from atmospheric pressure to 5.0−10.0 MPa are presented. An analysis of the working processes of the stage is performed in the course of operations in these regimes. The results confirm the assumptions that it is possible to compress gas in a single stage from atmospheric pressure to high pressures with an acceptable level of discharge temperature and with acceptable integral characteristics.
