摘要

FIELD: machine building.SUBSTANCE: invention relates to a radial expander. The radial expander comprises at least one section of the radial expander located in a common casing. The radial expander section includes impeller blades and a variety of diaphragms. The impeller blades are combined into two or more stages between the bearings on the same shaft. The diaphragms are coupled in axial direction. Every diaphragm comprises a knuckle bend to connect the adjacent stages. Each of the knuckle bends is fitted by a nozzle blade and a return blade. Every section has a gas input and a gas output. The gas input is communicated with the suction hole of the common casing. The gas output is communicated with the outlet hole of the common casing.EFFECT: invention is aimed at the increase of expander reliability.4 dwg
