Summary: | The invention discloses an efficient self-circulation treatment casing with a mode conversion function, which belongs to the technical field of air compressors and comprises an annular cavity, a plurality of flow deflectors and a mode conversion mechanism, and the annular cavity coaxial with the air compressor is formed in the inner side wall surface of the casing of a first-stage rotor or a second-stage rotor of the air compressor. According to the self-circulation treatment casing with the mode conversion function, when a self-circulation mode is opened, the pressure difference in a cavity is utilized, the strength of overflow of the front edge of a blade tip is weakened, development of gap leakage flow is restrained, a large-area backflow circulation area does not exist in a blade top channel, the circulation capacity of a rotor top channel is improved, and the service life of the rotor top channel is prolonged. And therefore, the flow loss of the blade top area is reduced, large-scale blocking clusters in |
