FIELD: power industry. ^ SUBSTANCE: invention can be used for axial, centrifugal and positive-displacement compressor and pump designing. Compressor comprises enclosure and assembly of stator and rotor wheels with reverse directional multistart threads, which contact by top area of bolt threads and compressor stage elements. Besides stator wheel is made of two cut halves or of two rings with cut external and internal grooves, which form a chamber with inlet and outlet openings for cooling agent supply and return line in stator wheel hub. On compressor enclosure there is a groove with pins for accurate installation of compressor stage. ^ EFFECT: decrease of low-frequency noise during compressor operation. ^ 8 dwg |
