Title (EN) METHOD FOR REGULATING THE LIQUID INJECTION OF A COMPRESSOR, A LIQUID-INJECTED COMPRESSOR AND A LIQUID-INJECTED COMPRESSOR ELEMENT
(FR) PROCÉDÉ DE RÉGULATION DE L'INJECTION DE LIQUIDE D'UN COMPRESSEUR, COMPRESSEUR À INJECTION DE LIQUIDE ET ÉLÉMENT COMPRESSEUR À INJECTION DE LIQUIDE
Abstract:
(EN) Method for controlling the liquid injection of a compressor device (1), whereby this compressor device comprises at least one compressor element (2), whereby the compressor element (2) comprises a housing (3) that comprises a compression space (4) in which at least one rotor (7) is rotatably affixed by means of bearings (8), whereby liquid is injected into the compressor element (2), characterised in that the method comprises the step of providing two independent separated liquid supplies to the compressor element (2), whereby one liquid supply is injected into the compression space (4) and the other liquid supply is injected at the location of the bearings (8).
(FR) L'invention concerne un procédé permettant de commander l'injection de liquide d'un dispositif compresseur (1), ce dispositif compresseur comprenant au moins un élément compresseur (2), l'élément compresseur (2) comprend un carter (3) qui comprend un espace de compression (4) dans lequel au moins un rotor (7) est fixé rotatif au moyen de paliers (8), le liquide étant injecté dans l'élément compresseur (2), caractérisé en ce que le procédé consiste à fournir deux alimentations liquides indépendantes séparées à l'élément compresseur (2), une alimentation liquide étant injectée dans l'espace de compression (4) et l'autre alimentation liquide étant injectée à l'emplacement des paliers (8).
