Abstract
Description
La présente invention concerne une pompe volumétrique du type "rotor-clapet séparateur" destinée au pompage de produits divers. The present invention relates to a positive displacement pump of the "rotor-separator valve" type intended for pumping various products.
Dans les pompes connues du genre en question, alimentées par une vis d'Archimède associée à une cuve et solidaire du moyeu du rotor de la pompe, le rotor est ovoïde et les ouvertures d'aspiration et de refoulement sont obligatoirement contenues dans une zone ne pouvant couvrir un secteur angulaire supérieur à 1800. In known pumps of the kind in question, fed by an Archimedes screw associated with a tank and integral with the hub of the pump rotor, the rotor is ovoid and the suction and discharge openings are necessarily contained in a zone not can cover an angular sector greater than 1800.
Ceci a pour conséquence d'interdire: - la possibilité d'avoir des ouvertures d'aspiration et de refoulement, directement pratiquées sur le corps de pompe cylindrique,en opposition sur un même diamètre; - la possibilité d'avoir, lorsque l'ouverture d'aspiration pratiquée sur la paroi transversale de la pompe est centrée en partie basse par rapport à la verticale, l'ouverture de refoulement en partie haute.This has the effect of prohibiting: - the possibility of having suction and discharge openings, directly made on the cylindrical pump body, in opposition on the same diameter; - The possibility of having, when the suction opening made on the transverse wall of the pump is centered in the lower part relative to the vertical, the delivery opening in the upper part.
La pompe, selon l'invention, permet de remédier à ces inconvénients. The pump according to the invention overcomes these drawbacks.
En effet, le remplacement d'un rotor ovoïde par un rotor à section en forme de triangle équilatéral, permet d'avoir les extrémités opposées des ouvertures d'aspiration et de refoulement, directement pratiquées dans le corps de pompe, dans une zone angulaire, par rapport à l'axe de la pompe, supérieureà1800, dans le sens de rotation du rotor.Indeed, the replacement of an ovoid rotor by a rotor with a section in the shape of an equilateral triangle, makes it possible to have the opposite ends of the suction and delivery openings, directly formed in the pump body, in an angular zone, relative to the pump axis, greater than 1800, in the direction of rotation of the rotor.
Cette caractéristique a en particulier pour conséquence de pouvoir pratiquer dans le corps de pompe des ouvertures d'aspiration et de refoulement en opposition partielle ou totale par rapport à l'axe de la pompe.This characteristic has in particular the consequence of being able to make in the pump body suction and delivery openings in partial or total opposition relative to the axis of the pump.
Les dessins annexés, donnés à titre d'exemple, permettront de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer. The appended drawings, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Sur ces dessins - la figure 1 représente, en coupe, une pompe à rotor ovoïde selon l'art connu, avec ouverture d'aspiration pratiquée dans la paroi - transversale de la pompe; - la figure 2 représente, en coupe, la pompe selon l'invention avec ouverture d'aspiration pratiquée dans la paroi transversale; - la figure 3 représente, en coupe, la pompe selon l'invention avec ouvertures d'aspiration et de refoulement diamétralement opposées. In these drawings - Figure 1 shows, in section, an ovoid rotor pump according to the prior art, with suction opening made in the wall - transverse to the pump; - Figure 2 shows, in section, the pump according to the invention with suction opening in the transverse wall; - Figure 3 shows, in section, the pump according to the invention with diametrically opposite suction and delivery openings.
La pompe représentée à la figure 1, du type connu, possède un rotor ovoïde (1), un corps de pompe cylindrique (2) délimitant l'enceinte de pompage, une paroi transversale (3) dans laquelle est pratiquée une ouverture d'aspiration (E) une ouverture de refoulement (S) débouchant directement dans le corps de pompe cylindrique, un clapet séparateur (4) évitant la communication des chambres d'aspiration et de refoulement. The pump shown in FIG. 1, of the known type, has an ovoid rotor (1), a cylindrical pump body (2) delimiting the pumping enclosure, a transverse wall (3) in which a suction opening is made. (E) a discharge opening (S) opening directly into the cylindrical pump body, a separating valve (4) preventing communication between the suction and discharge chambers.
Dans la représentation de la figure, la canalisation de refoulement (S) est verticale et située en partie haute, l'ouverture d'aspiration (E) est symétrique par rapport à l'axe horizontal. Les extrémités opposées des ouvertures d'aspiration (OB) et de refoulement (OA) forment un angle maximum de 1800. En effet au-delà il y aurait communication entre les ouvertures d'aspiration et de refoulement.In the representation of the figure, the discharge pipe (S) is vertical and located in the upper part, the suction opening (E) is symmetrical with respect to the horizontal axis. The opposite ends of the suction (OB) and discharge (OA) openings form a maximum angle of 1800. In fact beyond there would be communication between the suction and discharge openings.
La pompe représentée à la figure 2, selon l'invention, possède un rotor (1) en forme de triangle équilatéral. Les autres éléments (2),(3) et (4) restant identiques. Quant aux ouvertures d'aspiration (E) et de refoulement (S) - l'ouverture (E) est pratiquée sur la paroi transversale de la pompe en partie basse et centrée par rapport à l'axe vertical; - l'ouverture (S) est pratiquée sur la paroi cylindrique de la pompe en partie haute. The pump shown in Figure 2, according to the invention, has a rotor (1) in the shape of an equilateral triangle. The other elements (2), (3) and (4) remain identical. As for the suction (E) and discharge (S) openings - the opening (E) is made on the transverse wall of the pump at the bottom and centered with respect to the vertical axis; - The opening (S) is made on the cylindrical wall of the pump in the upper part.
L'angle (OA, OB) existant entre les extrémités opposées des ouvertures (E) et (S) peut dans ce cas atteindre 2400, dans le sens de rotation du rotor, autrement-dit il peut être supérieur à 1800.The angle (OA, OB) existing between the opposite ends of the openings (E) and (S) can in this case reach 2400, in the direction of rotation of the rotor, in other words it can be greater than 1800.
L'intêret d'avoir - (E) en partie basse permet une meilleure utilisation de la vis d'Archimède d'alimentation associée à une cuve cylindrique (5); - (S) en partie haute permetZen particulier dans les caves coopératives, d'avoir un meilleur refoulement vers par exemple les cuves de macération. The advantage of having - (E) in the lower part allows better use of the feed Archimedes screw associated with a cylindrical tank (5); - (S) in the upper part, in particular in cooperative cellars, to have better delivery towards, for example, the maceration tanks.
Dans la représentation de la figure où (OA, OB) mesure 2400, l'axe (OC) de la canalisation (S) forme avec la verticale un angle inférieur à 600.In the representation of the figure where (OA, OB) measures 2400, the axis (OC) of the pipe (S) forms with the vertical an angle less than 600.
La pompe représentée à la figure 3, selon l'invention possède les ouvertures d'aspiration et de refoulement en opposition par rapport à l'axe de la pompe. The pump shown in Figure 3, according to the invention has the suction and delivery openings in opposition relative to the axis of the pump.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté, pour lequel on pourra prévoir d'autres variantes, utiliser tous types de matériaux et l'étendre à d'autres applications sans pour cela sortir du cadre de l'invention. Of course, the invention is not limited to the embodiment described and shown, for which we can provide other variants, use all types of materials and extend it to other applications without departing from the scope of the invention.
