Title (EN) COMPRESSOR
(FR) COMPRESSEUR A VIS
Abstract:
(EN) A helical screw rotor compressor (K) adapted for working against a pressure container (T) whose pressure P is allowed to vary between a lowest pressure P2 and a highest pressure P1, said compressor being driven by an electric motor (M). The electric motor (M) is characterised by having in one operating range defined by the pressure interval P of said pressure container a quality such that halving of the torque of said motor will result an increase in motor speed of at least 6 percent. It is also preferred that the compressor is optimised for an internal volume factor at which the pressure of the compressor will be lower than P2+0.85* (P1-P2) at the opening instance.
(FR) L'invention concerne un compresseur (K) à rotor à vis hélicoïdale conçu pour travailler contre un contenant sous pression (T) dont la pression P peut varier entre une pression la plus basse P2 et une pression la plus haute P12, ledit compresseur étant entraîné par un moteur électrique (M). Le moteur électrique (M) est caractérisé en ce qu'il présente une gamme de fonctionnement définie par l'intervalle de pression P dudit contenant sous pression, une qualité telle que la réduction de moitié du couple dudit moteur a pour résultat une augmentation du régime moteur d'au moins 6 %. Il est également préféré que le compresseur soit optimisé pour avoir un facteur de volume intérieur auquel la pression du compresseur sera inférieure à P2+0,85* (P1-P2) au moment de l'ouverture.
