Abstract

The device has a rotating part (5) that is composed of discs (6) separated by a space (7) and integrated by an axle (9). An inner pipe (12) guiding the fluid is rotated by the part (5), so that the fluid traverses a pump casing (1) in a trajectory and turns from the axle of an inlet orifice (3) towards an outlet orifice (4), and the orifices are aligned on the same straight line parallel to sides of the pump casing. An independent claim is also included for a boat including a fluid pumping device.

Description

La présente invention concerne un dispositif de pompage centrifuge deThe present invention relates to a centrifugal pumping device of

fluide et son application comme propulseur.  fluid and its application as a propellant.

Dans une pompe centrifuge classique l'amenée du fluide au contact des roues à ailettes, se fait par un conduit parallèle ou coaxiale à l'axe de rotation et perpendiculaire à la sortie du fluide. Ceci oblige le fluide à effectuer des virages brusques par rapport à la trajectoire d'écoulement général. Certaines pompes sont équipées de conduits qui réalignent l'entrée et la sortie, mais les rayons de courbures de ces conduits entraînent des pertes de charges quand ils sont courts ou de l'encombrement autour du corps de pompe. La complexité des conduits affecte les coûts de réalisation. Ces inconvénients posent des difficultés d'utilisation des pompes centrifuges comme systèmes de propulsion et lors de leur intégration dans des systèmes à espace réduits.  In a conventional centrifugal pump the supply of fluid in contact with the finned wheels, is by a conduit parallel or coaxial with the axis of rotation and perpendicular to the fluid outlet. This forces the fluid to make sharp turns in relation to the overall flow path. Some pumps are equipped with ducts that realign the inlet and outlet, but the radii of curvature of these ducts cause losses when they are short or congestion around the pump body. The complexity of the conduits affects the costs of implementation. These disadvantages pose difficulties in using centrifugal pumps as propulsion systems and in their integration in reduced space systems.

Le dispositif selon l'invention remédie à ces inconvénients.  The device according to the invention overcomes these disadvantages.

Il comporte, selon une première caractéristique, une partie tournante composée de deux disques coaxiaux à ailettes, laissant un espace entre les surfaces des disques. L'entrée du fluide peut ainsi se faire entre les disques dans le corps de pompe muni d'un conduit interne dirigeant le fluide à travers le corps de pompe vers la sortie. L'entrée et la sortie du corps de pompe étant ainsi alignée, l'intégration du corps de pompe comme propulseur dans une coque de bateau ne nécessite aucune tuyauterie et la jonction du corps de pompe dans un circuit de pompage est facilitée. La trajectoire du conduit interne permet un grand rayon de courbure diminuant ainsi les pertes de charges avec un faible encombrement. Le conduit interne peut être réalisé simplement avec des plaques de séparation, diminuant ainsi les coûts de réalisation.  It comprises, according to a first feature, a rotating part composed of two coaxial fins disks, leaving a space between the surfaces of the disks. The fluid inlet can thus be between the disks in the pump body provided with an internal conduit directing the fluid through the pump body to the outlet. The inlet and the outlet of the pump body thus being aligned, the integration of the pump body as a thruster in a boat hull requires no piping and the junction of the pump body in a pumping circuit is facilitated. The path of the inner duct allows a large radius of curvature thus reducing the pressure losses with a small footprint. The internal duct can be made simply with separation plates, thus reducing the costs of production.

Selon des modes particuliers de réalisation: -le conduit interne peut être constitué de plaques fixée à l'intérieur du corps de pompe dans l'espace entre les disques de la partie mobile.  According to particular embodiments: the internal duct may consist of plates fixed inside the pump body in the space between the disks of the movable part.

- Les roues à ailettes peuvent comporter un disque percé en son centre fixé sur les ailettes.  - The finned wheels may comprise a disk pierced at its center fixed on the fins.

- les orifices d'entrée et de sortie peuvent êtres de formes cylindriques.  the inlet and outlet orifices can be cylindrical in shape.

- les orifices d'entrée et de sortie du fluide peuvent être directement percés dans Le corps de pompe.  - The inlet and outlet of the fluid can be directly drilled in the pump body.

-Le corps de pompe peut être équipe de profils hydrodynamiques.  -The pump body can be equipped with hydrodynamic profiles.

En référence à ces dessins, le dispositif comporte un corps de pompe (1), dont l'enveloppe arrondie (2) est munie d'orifices d'entrée (3) et de sortie (4).Dans ce corps de pompe (1) est disposée une partie tournante(5) , composée de deux disques (6) laissant un espace (7) entre leurs surfaces, munis d'ailettes(8), solidaires par un axe (9) tournant dans des paliers (10). Les parois (11) du conduit interne (12) perpendiculaire a l'axe (9) sont fixées à l'enveloppe (2) du corps de pompe (1) dans l'espace (7) entre les disques (6) de la partie tournante (5). Les parois (11) se séparent en deux parties vers la sortie (4). Le conduit interne (12) , formé par les parois (11) et le corps de pompe (1), guide le fluide, mis en mouvement par la rotation de la partie tournante (4).1e fluide traverse ainsi le corps de pompe(1) dans une trajectoire faisant le tour de l'axe (9) de l'entrée (2) vers la sortie (3) .Cette trajectoire permet l'alignement de l'entrée (2) et de la sortie (3) du fluide sur une même droite parallèle aux cotés (13) du corps de pompe(1) Une variante selon la figure 3 équipe les ailettes (8) de la partie tournante (4) 25 d'un disque percé en son centre (16).  With reference to these drawings, the device comprises a pump body (1), whose rounded envelope (2) is provided with inlet (3) and outlet (4) ports. In this pump body (1 ) is arranged a rotating part (5), consisting of two discs (6) leaving a space (7) between their surfaces, provided with fins (8), secured by an axis (9) rotating in bearings (10). The walls (11) of the inner duct (12) perpendicular to the axis (9) are fixed to the casing (2) of the pump casing (1) in the space (7) between the disks (6) of the rotating part (5). The walls (11) separate in two parts to the outlet (4). The inner duct (12), formed by the walls (11) and the pump body (1), guides the fluid, set in motion by the rotation of the rotating part (4) .1e fluid thus passes through the pump body ( 1) in a path around the axis (9) of the inlet (2) to the outlet (3) .This trajectory allows the alignment of the inlet (2) and the outlet (3) of the fluid on the same line parallel to the sides (13) of the pump body (1) A variant according to Figure 3 equips the fins (8) of the rotating part (4) 25 of a disk pierced at its center (16).

Dans une forme de réalisation selon la figure 5 les orifices d'entrée (3) et de sortie (4) sont de forme cylindrique permettant la jonction avec des tuyaux.  In one embodiment according to Figure 5 the inlet ports (3) and outlet (4) are of cylindrical shape for joining pipes.

Dans une forme de réalisation suivant la figure 6 et 7 l'enveloppe à été équipée de profils hydrodynamiques (14) pour l'utilisation comme propulseur intégré dans une coque (15) A titre d'exemple non limitatif le corps de pompe(1) a une largeur de 160 mm et un diamètre de 300 mm.  In an embodiment according to FIG. 6 and 7, the casing has been equipped with hydrodynamic profiles (14) for use as a propellant integrated into a shell (15). As a non-limiting example, the pump casing (1) has a width of 160 mm and a diameter of 300 mm.
