Summary:The present invention relates to a multistage fluid compressor comprising: a motor housing having a fluid injection port formed therein; a stator coupled to the inside of the motor housing; a rotor which penetrates through the inside of the stator and of which both sides in the axial direction are rotatably coupled to the motor housing; an impeller housing which is coupled to the motor housing to be in communication with the inside of the motor housing and is provided with a fluid outlet port that connects the inside to the outside; and a first impeller and a second impeller which are provided in the impeller housing and coupled to one end of the rotor. Thus, the compressor can be directly cooled by using a fluid to be compressed, and components of the compressor including a thrust bearing, the stator, and the rotor can be effectively cooled. La présente invention concerne un compresseur de fluide à plusieurs étages comprenant : un carter de moteur dans lequel est formé un orifice d'injection de fluide ; un stator accouplé à l'intérieur du carter de moteur ; un rotor qui pénètre à travers l'intérieur du stator et dont les deux côtés dans la direction axiale sont accouplés en rotation au carter de moteur ; un carter de roue qui est accouplé au carter de moteur pour être en communication avec l'intérieur du carter de moteur et qui est pourvu d'un orifice de sortie de fluide qui raccorde l'intérieur à l'extérieur ; et une première roue et une seconde roue qui sont disposées dans le carter de roue et sont accouplées à une extrémité du rotor. Ainsi, le compresseur peut être directement refroidi à l'aide d'un fluide à comprimer, et les composants du compresseur comprenant un palier de butée, le stator et le rotor peuvent être efficacement refroidis. 본 발명은 다단 유체 압축기에 관한 것으로, 유체 주입구가 형성된 모터 하우징; 상기 모터 하우징의 내측에 결합된 스테이터; 상기 스테이터의 내측을 관통하고 축방향 양측이 상기 모터 하우징에 회전 가능하게 결합된 로터; 상기 모터 하우징에 결합되어 상기 모터 하우징의 내부와 연통되며, 내부와 외부를 연결하는 유체 토출구가 형성된 임펠러 하우징; 및 상기 임펠러 하우징의 내부에 구비되며, 상기 로터의 일단에 결합된 제1임펠러 및 제2임펠러; 를 포함하여 이루어져, 압축하고자 하는 유체를 이용해 직접 압축기를 냉각시킬 수 있으며, 스러스트 베어링 및 스테이터와 로터를 포함한 압축기의 부품들을 효율적으로 냉각시킬 수 있는 다단 유체 압축기에 관한 것이다.
