Centrifugal compressors DEVICE strain of axial forces

摘要

The invention relates to the field of compressor and can be used in centrifugal compressors, which can reduce the volume loss and improve compressor reliability. The technical result in the achievement of which the claimed solution is to increase reliability and decrease in volume loss of the centrifugal compressor. Said technical result is achieved in that the centrifugal compressor comprising a casing with suction and discharge cavities, mounted therein on a shaft impellers and balance chamber forming a housing zadummisnuyu cavity connected to the suction cavity conduit, the shut-off valve installed in the pipeline, and the pipeline is provided with a bypass portion, wherein the choke installed.
