Evaluation of the prospects for the use of single-stage centrifugal compressors based on high-pressure stages with an inlet guide device at linear gas compressor stations

Abstract

The issues of evaluating the technical and economic prospects for the use of gas pumping units with single-stage centrifugal compressors with an axial suction nozzle, created on the basis of high-pressure stages with axial impellers and an adjustable inlet guide device, at linear gas compressor stations are considered. A brief description of the methodology for recalculating tests of a small compressor stage performed in air for working conditions as part of a gas compressor station is given. A comparative assessment of the competitiveness of the proposed compressor type with existing types of compressors in two-stage design has been performed.
