Title (EN) MACHINE PROVIDED WITH AN OIL PUMP AND A METHOD TO START SUCH A MACHINE.
(FR) MACHINE ÉQUIPÉE D'UNE POMPE À HUILE ET PROCÉDÉ DE DÉMARRAGE D'UNE TELLE MACHINE
Abstract:
(EN) Machine provided with a machine element (2) and an oil pump (4) and a motor (3) to drive the machine element (2) and the oil pump (4), whereby the oil pump (4) is provided with a shaft (13) with a rotor (12), whereby the oil pump (4) is provided to pump oil from an oil reservoir (5) via an inlet channel (8) to nozzles that lead into the motor (3) and/or machine element (2) to lubricate and/or cool one or more bearings or other machine components, characterized in that in the inlet channel (8), near the oil pump (4) a dam (16) is provided that is higher than the height (A) of the central axis (18) of the shaft (13) of the oil pump (4) minus the smallest diameter (B) of the rotor (12) of the oil pump (4) divided by two.
(FR) L'invention concerne une machine pourvue d'un élément de machine (2) et d'une pompe à huile (4) et d'un moteur (3) pour entraîner l'élément de machine (2) et la pompe à huile (4). La pompe à huile (4) est pourvue d'un arbre (13) avec un rotor (12) et est prévue pour pomper de l'huile à partir d'un réservoir d'huile (5) par l'intermédiaire d'un canal d'entrée (8) vers des buses qui conduisent dans le moteur (3) et/ou de l'élément de machine (2) afin de lubrifier et/ou refroidir un ou plusieurs paliers ou d'autres composants de machine. Cette machine est caractérisée en ce que, dans le canal d'entrée (8), à proximité de la pompe à huile (4), un barrage (16) soit prévu en étant supérieur à la hauteur (A) de l'axe central (18) de l'arbre (13) de la pompe à huile (4) soustrait du plus petit diamètre (B) du rotor (12) de la pompe à huile (4) divisé par deux.
