Abstract

The invention relates to a device making it possible to eliminate the frictional wear existing in all peristaltic pumps. It is essentially composed of a ring which is either flexible or rigid, and which is interposed between the pressing system or systems equipping hose pumps (peristaltic system). The device according to the invention is intended to improve the reliability of peristaltic pumps (with a tube).

Description

La présente invention concerne un dispositif permettant de
supprimer le frottement existant entre le tube et le dispositif
d'écrasement utilisé ( galets, patins, etc.... ) dans les pompes
fonctionnant suivant
le principe périStaftique . The present invention relates to a device for
eliminate the friction existing between the tube and the device
crushing used (rollers, skids, etc.) in the pumps
operating according to
the periStaftic principle.

Le fonctionnement de ce genre de pompe est pratiquement assuré
en comprimant progressivement un tube souple
L'inconvénient majeur de cette technique est
le frottement important que subit le tube, ce qui amène son usure
plus ou moins rapide, en fonction de la technique d'écrasement du
tube, du produit pompé, et de la pression de refoulement
Le dispositif selon l'invention permet de remédier à ce problème.The operation of this kind of pump is practically guaranteed
by gradually compressing a flexible tube
The major drawback of this technique is
the significant friction that the tube undergoes, which causes its wear
more or less fast, depending on the crushing technique of the
tube, pumped product, and discharge pressure
The device according to the invention overcomes this problem.

-Le dispositif comporte tout simplement une pièce intermédiaire
entre le sytème presseur et le tube
Dans le cas du montage de la figure 1, la pompe périStatique
classique à galets est équipée d'un anneau souple ( 4 ) qui ,remplace le contact direct du galet sur le tuyau par une simple
pression progressive ce qui évite d'user celui-ci par roulement.-The device simply includes an intermediate piece
between the pressure system and the tube
In the case of the assembly of figure 1, the peristatic pump
classic roller is equipped with a flexible ring (4) which replaces the direct contact of the roller on the pipe with a simple
progressive pressure which avoids using it in rotation.

Dans le cas du montage de lalfigure 2 la pompe périltastique
classique est cette fois équipée d'un anneau rigide ( 4 ) ce qui
conduit au même résultat
L'invention porte sur le montage de l'anneau souple ou rigide In the case of the assembly of figure 2 the periltastic pump
this time is equipped with a rigid ring (4) which
leads to the same result
The invention relates to the mounting of the flexible or rigid ring
