Title
(EN) COMPRESSOR
(FR) COMPRESSEUR
(ZH) 压缩机
Abstract
(EN)
A compressor, comprising: a housing (2); a motor stator (3) provided in the housing (2); a motor rotor (8) provided in the housing (2); a first gas bearing provided in the housing (2) and supporting the motor rotor (8); and an air supply flow channel provided in the housing (2), and used for being connected to an external air source and supplying working air provided by the external air source to the first air bearing; wherein the compressor is configured to allow the working gas that flows out of a gap between the first gas bearing and the motor rotor (8), and flows to a first side of the motor stator (3) by means of a gap between the motor stator (3) and the motor rotor (8) to be discharged from the housing (2); and the first side of the motor stator (3) is a side, away from the first gas bearing, of the motor stator (3) in an axial direction. The compressor can optimize an internal space of the compressor.
(FR)
Compresseur comprenant : un carter (2) ; un stator de moteur (3) disposé dans le carter (2) ; un rotor de moteur (8) disposé dans le carter (2) ; un premier palier à gaz disposé dans le carter (2) et supportant le rotor de moteur (8) ; et un canal d'écoulement d'alimentation en air disposé dans le carter (2) et utilisé pour être connecté à une source d'air externe et fournir de l'air opérationnel cédé par la source d'air externe au premier palier à air ; le compresseur étant configuré pour permettre au gaz opérationnel qui s'écoule hors d'un espace, situé entre le premier palier à gaz et le rotor de moteur (8), jusqu'à un premier côté du stator de moteur (3) au moyen d'un espace situé entre le stator de moteur (3) et le rotor de moteur (8) pour être évacué du carter (2 ) ; et le premier côté du stator de moteur (3) est un côté, à l'opposé du premier palier à gaz, du stator de moteur (3) dans une direction axiale. Le compresseur peut optimiser un espace intérieur du compresseur.
