Title (EN) AIR COMPRESSOR
(FR) COMPRESSEUR D'AIR
(JA) 空気圧縮機
Abstract:
(EN) An oil - cooled air compressor is provided with: an oil - cooled air compressor for compressing sucked-in air and discharging the compressed air; an oil separator for separating the compressed air and lubricating oil, which are discharged from the air compressor body; an oil cooler for cooling, by means of outside air, lubricating oil discharged from the oil separator; oil supply pipe passage for supplying lubricating oil, which is discharged from the oil cooler, to a bearing of the air compressor body and to an intermediate section in the process of compression by the air compressor; and an after-cooler for cooling, by means of outside air, air discharged from the oil separator. The oil-cooled air compressor in which the air compressor, the oil separator, the oil cooler, and the after-cooler are connected to supply high-pressure air to the outside of the compressor is provided with a vapor compression type refrigeration cycle.
(FR) L'invention concerne un compresseur d'air refroidi à l'huile, comprenant : un compresseur d'air refroidi à l'huile pour comprimer de l'air aspiré et décharger l'air comprimé ; un séparateur d'huile pour séparer l'air comprimé et l'huile de lubrification, qui sont déchargés du corps de compresseur d'air ; un refroidisseur d'huile pour refroidir, au moyen de l'air extérieur, l'huile de lubrification déchargée du séparateur d'huile ; un passage de tuyau d'alimentation en huile pour alimenter l'huile de lubrification, qui est déchargée du refroidisseur d'huile, vers un roulement du corps de compresseur d'air et vers une section intermédiaire au moment du processus de compression par le compresseur d'air ; et un post-refroidisseur pour refroidir, au moyen de l'air extérieur, l'air déchargé du séparateur d'huile. Le compresseur d'air refroidi à l'huile, dans lequel le compresseur d'air, le séparateur d'huile, le refroidisseur d'huile et le post-refroidisseur sont connectés pour alimenter de l'air haute pression à l'extérieur du compresseur, comprend un cycle de réfrigération du type à compression de vapeur.
(JA) 吸引した空気を圧縮して吐出する油冷式の空気圧縮機、前記空気圧縮機本体から吐出された圧縮空気と潤滑油を分離する油分離器、前記油分離器から吐出した潤滑油を外気で冷却するオイルクーラ、前記オイルクーラから吐出した潤滑油を前記空気圧縮機本体の軸受および空気圧縮機の圧縮途中の中間部に給油するための給油管路、前記油分離器から吐出した空気を外気で冷却するアフタークーラとを備え、前記空気圧縮機、前記油分離器、前記オイルクーラ、および前記アフタークーラとを接続して高圧空気を圧縮機外へ供給する油冷式の空気圧縮機において、蒸気圧縮式の冷凍サイクルを設けた。
