Title (EN) VIBRATIONLESS MOINEAU SYSTEM
(FR) SYSTÈME MOINEAU SANS VIBRATION
Abstract:
(EN) A method of operating a Moineau system to substantially eliminate vibrations, the method includes rotating a first rotational member, and rotating a second rotational member. Each of the first rotational member and the second rotational member includes a plurality of lobes. A first rotational speed of one of the first rotational member and the second rotational member is selected based on 1) a second rotational speed of the other of the first rotational member and the second rotational member and 2) the number of lobes of one of the first rotational member and the second rotational member to maintain eccentric force of one of the first and second rotational members below a predetermined threshold.
(FR) L'invention concerne un procédé de fonctionnement d'un système Moineau permettant d'éliminer sensiblement les vibrations, le procédé consistant à faire tourner un premier élément rotatif, et à faire tourner un second élément rotatif. Chacun du premier élément rotatif et du second élément rotatif comprend une pluralité de lobes. Une première vitesse de rotation du premier élément rotatif ou du second élément rotatif est sélectionnée sur la base 1) d'une seconde vitesse de rotation de l'autre élément parmi le premier élément rotatif et le second élément rotatif et 2) du nombre de lobes du premier élément rotatif ou du second élément rotatif pour maintenir une force excentrique du premier ou du second élément rotatifs au-dessous d'un seuil prédéterminé.
