Title (EN) AIR COMPRESSOR
(FR) COMPRESSEUR D'AIR
(KO) 공기압축기
Abstract:
(EN) The present invention relates to an air compressor which may comprise: a compressor part including a front housing and a compressor impeller, wherein the front housing is provided with a front inlet through which air is introduced and a compressor blower which compresses the introduced air, and the compressor impeller is disposed between the front inlet and the compressor blower and transports the air introduced from the front inlet toward the compressor blower; a motor part including a motor housing connected to the front housing, a stator disposed along the inner circumferential surface of the motor housing, and a rotor that is disposed passing through the central axis of the stator and is connected to the compressor impeller via a rotary shaft; a turbine part including a rear housing connected to the motor housing, a turbine impeller connected to the rotary shaft, and a turbine blower that is formed in the rear housing and discharges the air, which has passed through the turbine impeller, to the outside; and an air cooling part which is disposed connected to the compressor blower so as to cool the stator and the rotary shaft by receiving a supply of compressed air from the compressor blower. According to the present invention, the air compressor has the effects of: effectively cooling the stator and rotator and various bearings by using a portion of the compressed air that flows though the compressor blower; and increasing the reuse rate of the compressed air.
(FR) La présente invention concerne un compresseur d'air qui peut comprendre : une partie compresseur comprenant un logement avant et un rouet de compresseur, le logement avant étant pourvu d'une entrée avant à travers laquelle de l'air est introduit et d'une soufflante de compresseur qui comprime l'air introduit, et le rouet de compresseur est disposé entre l'entrée avant et la soufflante de compresseur et transporte l'air introduit à partir de l'entrée avant vers la soufflante de compresseur ; une partie moteur comprenant un logement de moteur raccordé au logement avant, un stator disposé le long de la surface circonférentielle interne du logement de moteur, et un rotor qui est disposé à travers l'axe central du stator et qui est raccordé au rouet de compresseur par l'intermédiaire d'un arbre rotatif ; une partie turbine comprenant un logement arrière raccordé au logement de moteur, une roue de turbine raccordée à l'arbre rotatif, et une soufflante de turbine qui est formée dans le logement arrière et évacue l'air, qui a traversé la roue de turbine, vers l'extérieur ; et une partie de refroidissement à air qui est disposée de façon à refroidir le stator et l'arbre rotatif en recevant une alimentation en air comprimé provenant de la soufflante de compresseur. Selon la présente invention, le compresseur d'air présente les effets suivants : il permet de refroidir efficacement le stator et le rotateur et divers paliers en utilisant une partie de l'air comprimé qui s'écoule à travers la soufflante de compresseur ; et il permet d'augmenter le taux de réutilisation de l'air comprimé.
(KO) 본 발명은 공기압축기에 관한 것으로, 공기가 유입되는 전면유입구와 유입된 공기를 압축하는 압축기블로우를 구비하는 전면하우징 및 상기 전면유입구와 상기 압축기블록우 사이에 배치되고 상기 전면유입구에서 유입된 공기를 상기 압축기블로우 방향으로 이송하는 압축기임펠러를 포함하는 압축기부; 상기 전면하우징과 연결되는 모터하우징과 모터하우징의 내주면을 따라 배치되는 고정자 및 상기 고정자의 중앙측을 관통하며 배치되고 상기 압축기임펠러와 회전축으로 연결된 회전자를 포함하는 모터부; 상기 모터하우징과 연결되는 후면하우징과 상기 회전축과 연결되는 터빈임펠러 및 상기 후면하우징에 형성되고 상기 터빈임펠러를 통과한 공기를 외부로 배출하는 터빈블로우를 포함하는 터빈부; 및 상기 압축기블로우로부터 압축공기를 공급받아, 고정자와 상기 회전축을 냉각하도록, 상기 압축기블로우와 연결되며 배치되는 공기냉각부;를 포함하여 구성될 수 있으며, 본 발명에 따르면, 압축기블로우를 흐르는 압축공기의 일부를 이용하여 고정자와 회전자 및 각종베어링을 효과적으로 냉각하고 압축공기의 재사용율을 높이는 효과가 있다.
