Title
(EN) COMPRESSOR

(ZH) 压缩机
Abstract
(EN)
Disclosed is a compressor, comprising a moving disk (1), cooling pipes and a crankshaft (3), wherein the cooling pipes comprise an inlet pipe (9) and an outlet pipe (10); an axial through hole (16) is provided at the center of the moving disk (1); a sealing portion of the moving disk (1) is provided with a sealing groove (15); a mounting hole (17) is provided in the crankshaft (3); the cooling pipes are arranged in the crankshaft (3) in a penetrating manner; the cooling pipes enter from a tail portion of the crankshaft (3), pass through the mounting hole (17), the axial through hole (16) and the sealing groove (15), and then return along an original path thereof; and part of each cooling pipe is arranged in the sealing portion of the moving disk (1), and the cooling pipes move synchronously with the moving disk (1) and rotate relative to the crankshaft (3). By providing the cooling pipes, the temperature of a sealing component of the compressor can be effectively reduced, thereby prolonging the service life of the sealing component.
(FR)
L'invention concerne un compresseur, comprenant un disque mobile (1), des tuyaux de refroidissement et un vilebrequin (3), les tuyaux de refroidissement comprenant un tuyau d'entrée (9) et un tuyau de sortie (10) ; un trou traversant axial (16) est ménagé au centre du disque mobile (1) ; une rainure d'étanchéité (15) est ménagée dans une partie d'étanchéité du disque mobile (1) ; un trou de montage (17) est ménagé dans le vilebrequin (3) ; les tuyaux de refroidissement sont agencés dans le vilebrequin (3) de manière pénétrante ; les tuyaux de refroidissement entrent à partir d'une partie queue du vilebrequin (3), passent à travers le trou de montage (17), le trou traversant axial (16) et la rainure d'étanchéité (15), puis reviennent le long de leur trajet d'origine ; et une partie de chaque tuyau de refroidissement est disposée dans la partie d'étanchéité du disque mobile (1) et les tuyaux de refroidissement bougent de manière synchrone avec le disque mobile (1) et tournent par rapport au vilebrequin (3). En utilisant les tuyaux de refroidissement, la température d'un composant d'étanchéité du compresseur peut être efficacement réduite, ce qui permet de prolonger la durée de vie du composant d'étanchéité.
