Title
(EN) CENTRIFUGAL COMPRESSOR USING AN ASYMMETRIC SELF-RECIRCULATING CASING TREATMENT
(FR) COMPRESSEUR CENTRIFUGE FAISANT APPEL À UN TRAITEMENT POUR CARTER À RECIRCULATION AUTOMATIQUE ASYMÉTRIQUE

Abstract
(EN) Provided is a centrifugal compressor using an asymmetric self-recirculating casing treatment, in which the inside surface of a casing (10) has a suction ring groove (1), a ring guide path (2), and a back-flow ring groove (3), forming a self-recirculation channel. The position or width of the suction ring groove (1) forms an arc in the circumferential direction, with the central angle (α) of said arc being in the range 0 < α ≤ 30°.
(FR) La présente invention se rapporte à un compresseur centrifuge faisant appel à un traitement pour carter à recirculation automatique asymétrique, dans lequel la surface intérieure d'un carter (10) comporte une rainure annulaire d'aspiration (1), un chemin de guidage annulaire (2), et une rainure annulaire de refoulement (3), formant un canal de recirculation automatique. La position ou largeur de la rainure annulaire d'aspiration (1) forme un arc dans la direction circonférentielle, l'angle central (α) dudit arc se trouvant dans la plage 0 < α ≤ 30°.
(JA)  ケーシング10の内周面に吸引リング溝1、リング案内路2、及び還流リング溝3を有し、自己循環流路を形成する非対称自己循環ケーシングトリートメントを有する遠心圧縮機において、吸引リング溝1の位置又は幅が、周方向において円弧状に分布し、円弧の中心角αが0<α≦30°の範囲である。
