Definitions

  • the transversal cross section through the grooving has an advantageous shape of isosceles triangle of height between approx. 0.15 and 0.50 mm, depending on the pump segment radius and thickness of its wall.
  • the linear dependence of the dosing volume on the number of steps (rotor movement angle) obtainable in practice enables usage of software correction of the accuracy of the dosed volume for any chosen dose within individual calibration of a particular pump segment used, and thus increase substantially the accuracy range of the whole unit for a declared pumping dose.
  • the peristaltic rotation pump with exact dosage has the following advantages against the previous solutions:

Abstract

L'invention concerne une pompe péristaltique rotative basée sur le fait que le segment de pompe (1), le long du chemin de travail (24), comporte des rainures transversales à l'emplacement de contact avec le segment de pompage comprimé (1), et qu'il est adjacent sur toute sa longueur à un chemin d'occlusion à support circulaire élevé (3), pour le roulement des galets de pression (4). Le chemin de travail (24) est constitué d'un chemin de prise (15), d'un chemin d'occlusion (2) et d'un chemin de libération (16). La linéarité mécanique du dosage est assurée par un chemin d'occlusion circulaire (2) et par le chemin de libération presque circulaire (16), adjacent sur toute sa longueur au chemin d'occlusion à support circulaire élevé (3) destiné au roulement d'au moins trois galets de pression (4). La longueur de l'angle du chemin de libération (16), correspondant à la distance entre le point du début de libération du segment de pompe (1) et le point de libération complète de ce segment (1) par le galet de pression (4), est identique à celle du chemin d'occlusion (2).
