Title (EN) MULTICHANNEL PERISTALTIC DOSING PUMP
(FR) POMPE DE DOSAGE PERISTALTIQUE MULTICANAL
Abstract:
(EN) A multichannel peristaltic pump comprises a multiplicity of elastomeric pump tubes (1), acted upon by a common inlet valve member (2) and a common discharge valve member (4), conveniently formed as transverse bars that occlude the pump tubes (1) between the inlet valve and discharge valve form a plurality of pumping chambers, one for each pump tube, which are acted upon by a common displacer (3), conveniently formed as a rectangular plate. Sequencing of the inlet and discharge valves, and the displacer (3) is facilitated by cams (11 and 12). Each channel of the pump is provided with an individually movable section of pump frame (7), the position of which can be adjusted by a sliding wedge (8). By adjustment of the movable sections of pump frame (7), the volume of fluid delivered by each channel can be individually trimmed with respect to the others to ensure accurate balancing of the flow through each channel.
(FR) L'invention concerne une pompe péristaltique multicanal comportant une pluralité de tubes en élastomère (1) actionnés par une soupape d'aspiration commune (2) et une soupape de refoulement commune (4) prenant la forme de barres transversales fermant les tubes (1) de la pompe entre la soupape d'aspiration et la soupape de refoulement, cette partie des tubes formant une pluralité de chambres de pompage, une pour chaque tube de la pompe. Ces tubes sont actionnés par un plongeur commun (3) prenant la forme d'une plaque rectangulaire. La commande séquentielle des soupapes d'aspiration et de refoulement et du plongeur (3) est réalisée au moyen de cames (11 et 12). Chaque canal de la pompe est fixé sur une partie individuellement mobile de l'armature de la pompe (7), et dont la position peut être réglée au moyen d'un coin coulissant (8). Grâce au réglage des parties mobiles de l'armature de la pompe (7), on peut ajuster le volume de fluide libéré par chaque canal de manière individuelle par rapport aux autres canaux et ce, dans le but d'assurer un équilibrage précis de l'écoulement dans les différents canaux.
