Title
(EN) OIL-INJECTED MULTISTAGE COMPRESSOR DEVICE AND METHOD FOR CONTROLLING SUCH A COMPRESSOR DEVICE
(FR) DISPOSITIF DE COMPRESSEUR D'ÉTAGES MULTIPLES À INJECTION D'HUILE ET PROCÉDÉ DE COMMANDE D'UN TEL DISPOSITIF DE COMPRESSEUR
Abstract
(EN)
An oil-injected multistage compressor device that comprises at least one low-pressure stage compressor element (2) with an inlet (4a) and an outlet (5a) and a high-pressure stage compressor element (3) with an inlet (4b) and an outlet (5b), whereby the outlet (5a) of the low-pressure stage compressor element (2) is connected to the inlet (4b) of the high-pressure stage compressor element (3) via a conduit (6), characterized in that an intercooler (9) is provided.between the low-pressure stage compressor element (2) and the high-pressure stage compressor element (3) in the aforementioned conduit (6) and that the compressor device (1) is also equipped with a restriction (10) for limiting the amount of oil injected in the low-pressure stage compressor element (2).
(FR)
L'invention concerne un dispositif de compresseur d'étages multiples à injection d'huile qui comprend au moins un élément de compresseur d'étage basse pression (2) doté d'une entrée (4a) et d'une sortie (5a) et un élément de compresseur d'étage haute pression (3) doté d'une entrée (4b) et d'une sortie (5b), la sortie (5a) de l'élément de compresseur d'étage basse pression (2) étant raccordée à l'entrée (4b) de l'élément de compresseur d'étage haute pression (3) par l'intermédiaire d'un conduit (6), caractérisé en ce qu'un refroidisseur intermédiaire (9) est disposé entre l'élément de compresseur d'étage basse pression (2) et l'élément de compresseur d'étage haute pression (3) dans le conduit susmentionné (6) et en ce que le dispositif de compresseur (1) est également équipé d'une restriction (10) destinée à limiter la quantité d'huile injectée dans l'élément de compresseur d'étage basse pression (2).
