Abstract

The invention relates to an axial and radial flowing compressor with an axial chute processor casing structure, belonging to the technical field of impeller machinery; the axial and radial flowing compressor comprises an axial flowing rotor, an axial flowing stator and a radial-flowing compressor which are coaxially connected sequentially; axial chutes which are circumferentially distributed uniformly are processed on a casing wall surface of the axial flowing rotor of the axial and radial flowing compressor, the axial chute is radially inclined with 30-60 degrees along the rotating direction of the rotor. In the axial and radial flowing compressor with the axial chute processor casing structure, the low-energy tip clearance vortex of axial-flowing grade blade tip can be effectively controlled under the pumping action of the axial chute processor casing on the axial flowing rotor, flow separation is inhibited under a low flow-rate condition, the entrance condition of the radial flowing compressor is improved, so as to improve surge-to-stall margin of the axial and radial flowing compressor greatly on the premise of ensuring the little change of pressure ratio and efficiency.
