Title
(EN) CENTRIFUGAL COMPRESSOR AND CLEANING METHOD
(FR) COMPRESSEUR CENTRIFUGE ET PROCÉDÉ DE NETTOYAGE
(JA) 遠心圧縮機、および洗浄方法
Abstract
(EN) A centrifugal compressor is provided with a casing, a rotating shaft which is supported within the casing, an impeller which is provided to the rotating shaft and rotates to compress fluid, and a cleaning liquid ejection device which ejects a cleaning liquid into the flow path formed by the impeller and the casing. The cleaning liquid ejection device is provided with: nozzles which are arranged in the circumferential direction of the rotating shaft and which eject the cleaning liquid into the flow path; and chambers which communicate with corresponding nozzles among the nozzles and which supply the cleaning liquid to the corresponding nozzles.
(FR) L'invention concerne un compresseur centrifuge muni d'un carter, d'un arbre rotatif qui est supporté dans le carter, d'une hélice qui est fournie à l'arbre rotatif et tourne pour comprimer un fluide, et d'un dispositif d'éjection de liquide de nettoyage qui éjecte un liquide de nettoyage dans le trajet d'écoulement formé par l'hélice et le carter. Le dispositif d'éjection de liquide de nettoyage est pourvu : de buses qui sont agencées dans la direction circonférentielle de l'arbre rotatif et qui éjectent le liquide de nettoyage dans le trajet d'écoulement ; et de chambres qui communiquent avec des buses correspondantes parmi les buses et qui fournissent le liquide de nettoyage aux buses correspondantes.
(JA)  この遠心圧縮機は、ケーシングと、このケーシング内に支持された回転軸と、この回転軸に設けられ回転して流体を圧縮するインペラと、このインペラと前記ケーシングとにより形成される流路に洗浄液を噴射する洗浄液噴射装置とを備える。前記洗浄液噴射装置は、前記回転軸の周方向に沿って設けられ、前記流路内に前記洗浄液を噴射させる複数のノズルと、これら複数のノズルのうち、対応するノズルと連通し、この対応するノズルに前記洗浄液を供給する複数のチャンバとを有する。
