Title (EN) PERISTALTIC PUMP
(FR) POMPE PERISTALTIQUE
Abstract: front page image
(EN)The peristaltic pump comprises several cylinders (5) rotated by a planetary gearing from a central gearing (3); these cylinders are rolling over at least one hose which conducts the fluid through compression of the free section of the hose. There is provided a counter-pressure body (11) passing the hose (10) against at least a cylinder (5); this body is held on a base plate (15) so as to slide in a radial direction with respect to the central gearing (3); it is taut by at least one spring towards the central gearing (3) Upon replacing the hose, the new hose is thereby located only within the counter-pressure body and, by tightening the counter-pressure body by means of the springs, a sufficient pressing is achieved for ensuring a functional efficiency of the pump. Furthermore, the tolerances in the mounting and the hoses are compensated by the counter-pressure body acting as a spring.
(FR)La pompe peristaltique comporte plusieurs cylindres (5) mis en rotation par un engrenage planetaire a partir d'un engrenage central (3); ces cylindres roulent sur au moins un boyau (10) qu conduit le fluide par compression de la section libre du boyau. Il est prevu un corps de contre-pression (11) serrant le boyau (10) contre au moins un cylindre (5); ce corps est tenu sur une plaque de base (15) de maniere a coulisser dans une direction radiale par rapport a l'engrenage central (3); il est tendu par au moins un ressort en direction de l'engrenage central (3). Ainsi, en changeant le boyau, le nouveau boyau est place uniquement dans le corps de contre-pression et deja, en tendant le corps de contre-pression au moyen des ressorts, on assure un serrage suffisant pour garantir une efficacite fonctionnelle de la pompe. En outre, les tolerances dans le montage et les boyaux memes sont compensees par le corps de contre-pression faisant ressort.
