Abstract
(EN)
Provided in the present disclosure are a compressor rotor, a compressor, and a refrigerant circulation system. The compressor rotor comprises: a motor rotor, comprising a plurality of rotor sections fixedly connected along the axial direction, the plurality of rotor sections having an axial through hole; a locking rod penetrating through the axial through holes; a compression unit rotating part positioned on the end part of the motor rotor and being connected onto the locking rod; and a locking component for locking the compression unit rotating part onto the locking rod, the locking rod, the compression unit rotating part, and the locking component forming a pressing structure for applying pressure towards the axial inner side of the motor rotor. The compressor rotor of the present disclosure enables section-by-section processing of the motor rotor, and makes the connection between the rotor sections of the motor rotor with a plurality of rotor sections firmer and more reliable.

La présente invention concerne un rotor de compresseur, un compresseur, et un système de circulation de réfrigérant. Le rotor de compresseur comprend : un rotor de moteur, comprenant une pluralité de sections de rotor reliées de manière fixe le long de la direction axiale, la pluralité de sections de rotor ayant un trou traversant axial ; une tige de verrouillage pénétrant à travers les trous traversants axiaux ; une partie de rotation d'unité de compression positionnée sur la partie d'extrémité du rotor de moteur et reliée à la tige de verrouillage ; et un élément de verrouillage destiné à verrouiller la partie de rotation d'unité de compression sur la tige de verrouillage, la tige de verrouillage, la partie de rotation d'unité de compression, et le composant de verrouillage formant une structure de pression destinée à appliquer une pression vers le côté interne axial du rotor de moteur. Le rotor de compresseur de la présente invention permet un traitement section par section du rotor de moteur, et effectue la liaison entre les sections de rotor du rotor de moteur à l'aide d'une pluralité de sections de rotor plus solides et plus fiables.
