Abstract

The pump consists of a steel casing (1) supported on a pedestal (2) and housing the main shaft bearing (1), the shaft seal (5) and also incorporating the discharge volute (4). The sectional multi-stage casing (10) is located on the collar (9) and assembled along with the impellers (11) on the extended shaft. The outer casing (12) is not subject to any pipework loads and is made from a plastics. This is bolted to the body and forms the suction passage of the pump and also houses the end shaft bearing (14). The pump can be dismantled without disturbing the adjustment of the pump and motor.

Description

La présente invention concerne les pompes à hydraulique multicellulaire. The present invention relates to multicellular hydraulic pumps.

Une pompe à hydraulique multicellulaire est difficile à fabriquer car il faut d'une part usiner les formes relativement compliquées de l'hydraulique multicellulaire, et d'autre part donner à la pompe la résistance mécanique qui lui permettra de supporter les efforts et les tensions provoqués par les poids et les raccordements des conduites et par leur dilatation. A multicellular hydraulic pump is difficult to manufacture because on the one hand it is necessary to machine the relatively complicated forms of multicellular hydraulics, and on the other hand to give the pump the mechanical resistance which will allow it to withstand the forces and tensions caused by the weights and connections of the pipes and by their expansion.

L'invention repose sur la reco-nnaiss nce de cette dualité des fonctions et sur leur séparation, de, manière à obtenir une pompe peu couteuse et aisée à fabriquer, malgré la forme compliquée de l'hydraulique, et qui a néanmoins la résistance mécanique requise. The invention is based on the recognition of this duality of functions and their separation, so as to obtain an inexpensive pump which is easy to manufacture, despite the complicated form of the hydraulics, and which nevertheless has the mechanical resistance. required.

L'invention a donc pour objet une pompe comprenant un corps (1), ayant une tubulure d'aspiration (3) (ou de refoulement), et une hydraulique (10) multicellulaire, dont l'une des extrémités communique avec une tubulure de refoulement (4) ou d'aspiration), caractérisée en ce que l'hydraulique (10) multicellulaire est montée en porte-à-faux sur le corps (1) et l'intervalle (15) compris entre l'enveloppe (12) et l'hydraulique multicellulaire (10) débouche d'une part dans la tubulure (4) de refoulement (ou d'aspiration) qui est ménagée sur le corps (1), et d'autre part vers ltextrémité de l'hydraulique (10) cellulaire qui est la plus éloignée du corps (1). The invention therefore relates to a pump comprising a body (1), having a suction pipe (3) (or discharge), and a hydraulic (10) multicellular, one end of which communicates with a pipe delivery (4) or suction), characterized in that the multicellular hydraulics (10) is mounted in cantilever on the body (1) and the interval (15) between the casing (12) and the multicellular hydraulics (10) opens on the one hand into the delivery pipe (4) (or suction) which is formed on the body (1), and on the other hand towards the end of the hydraulics (10 ) cell which is furthest from the body (1).

Le corps, en une matière résistante du point de vue mécanique, par exemple en métal, est d'une forme plus simple que l'hydraulique multicellulaire. Comme c'est sur lui que sont montés tous les raccords et tubulures, c'est sur lui et lui seul que sont reportées toutes les exigences de résistance mécanique, tandis que l'hydraulique cellulaire, qui n'a plus à s'accommoder d'efforts mécaniques importants, peut être en une matière plastique, de préférence légère, peu coûteuse. The body, made of a mechanically resistant material, for example metal, is of a simpler form than multicellular hydraulics. As it is on him that all the fittings and tubing are mounted, it is on him and he alone that all the requirements for mechanical resistance are transferred, while cellular hydraulics, which no longer has to accommodate d 'significant mechanical forces, can be of a plastic material, preferably light, inexpensive.

Le corps de pompe métallique supporte la poussée axiale due à l'hydraulique multicellulaire. Le montage en porte-à-faux permet de démonter l'hydraulique multicellulaire sans démonter les tuyauteries et sans désaligner le groupe. Le démontage est' encore plus rapide si l'hydraulique multicellulaire est emmanchée dans des collets du corps. I1 suffit alors de déboulonner l'enveloppe et de désemmancher celle-ci pour effectuer un échange. The metal pump body supports the axial thrust due to the multicellular hydraulics. The cantilever mounting allows the multicellular hydraulics to be dismantled without dismantling the pipes and without misaligning the group. Disassembly is even faster if the multicellular hydraulics are fitted into the body's collars. I1 then suffices to unbolt the envelope and to disengage it to carry out an exchange.

Au dessin annexé, donné uniquement à titre d'exemple
La figure 1 est une vue en coupe, suivant un plan passant par l'axe de l'hydraulique multicellulaire, d'une pompe suivant l'invention, tandis que la figure 2 est une vue en bout de la pompe.
In the accompanying drawing, given only by way of example
Figure 1 is a sectional view, along a plane passing through the axis of the multicellular hydraulics, of a pump according to the invention, while Figure 2 is an end view of the pump.

Un corps 1 de pompe, en fonte, formant bâti et porté par des pieds 2, supporte des tubulures d'aspiration 3 et de refoulement 4, ainsi qu'un système 5 d'étanchéité. A pump body 1, made of cast iron, forming a frame and carried by feet 2, supports suction 3 and discharge 4 pipes, as well as a sealing system 5.

I1 est traversé par un arbre 6 monté sur des roulements 7 et entraîné par un moteur 8. L'arbre 6 s'étend des deux côtés du corps 1. I1 is crossed by a shaft 6 mounted on bearings 7 and driven by a motor 8. The shaft 6 extends on both sides of the body 1.

Du côté opposé au moteur 8, le corps 1 présente trois collets 9 sur lesquels sont emmanchées en porte-à-faux les pièces 10 formant diffuseurs et éléments d'une hydraulique multicellulaire, tandis que les aubes 11 de l'hydraulique sont calées sur l'arbre 6. On the side opposite to the motor 8, the body 1 has three collars 9 on which are fitted cantilever the parts 10 forming diffusers and elements of a multicellular hydraulics, while the vanes 11 of the hydraulics are fixed on the tree 6.

Une enveloppe 12, en matière plastique comme l'hydrau- lique, entoure celle-ci et est boulonnée au corps 1 en porte-à-faux par des boulons 13. Dans le fond de ltenveloppe est prévu un coussinet 14 pour l'arbre 6 . L'enveloppe 12 définit avec les pièces 10 un intervalle 15 annulaire, communiquant avec la tubulure 3 et avec ltextremité de l'hydraulique qui est la plus éloignée du corps 1. L'aspiration se fait par l'intervalle 15 qui guide le liquide jusqu'à l'aube 11 la plus éloignée du corps 1. A casing 12, made of plastic such as hydraulic, surrounds it and is bolted to the body 1 in overhang by bolts 13. In the bottom of the casing is provided a bushing 14 for the shaft 6 . The envelope 12 defines with the parts 10 an annular interval 15, communicating with the tube 3 and with the end of the hydraulics which is furthest from the body 1. The suction takes place through the interval 15 which guides the liquid up to 'at dawn 11 furthest from the body 1.

Suivant une autre variante, l'intervalle 15 communique avec la tubulure de refoulement. L'aube la plus proche du corps, conformée en conséquence, refoule le liquide dans l'intervalle 15, lequel guide le liquide jusqu'à la tubulure de refoulement.  According to another variant, the interval 15 communicates with the delivery pipe. The dawn closest to the body, shaped accordingly, discharges the liquid in the interval 15, which guides the liquid to the delivery pipe.
