Description

L'invention concerne une pompe hydraulique à piston, submergée, à transmission hydrodhynamique.The invention relates to a hydraulic submersible piston pump with hydrodhynamic transmission.

On sait que les pompes hydrauliques à piston, à mou vement alternatif,à effet simple ou double, à un ou plusieurs cylindres, avec piston à disque ou plongeur, simple ou différentiel, avec commande manuelle ou à moteur, actuellement connues prévoient que la tige du piston soit actionnée au moyen d'une transmission mécanique qui peut être de type à balancier, avec arbre à manivelle ou à disque oblique ou à siège rotatif, etc.It is known that hydraulic piston pumps, with reciprocating movement, with single or double effect, with one or more cylinders, with disc or plunger piston, simple or differential, with manual or motor control, currently known provide that the rod the piston is actuated by means of a mechanical transmission which can be of the pendulum type, with crankshaft or oblique disc or rotary seat, etc.

En conséquence, la portée et la hauteur d'élévation de ces pompes de type connu dépendent de la force de commande adoptée, de la dimension et du nombre de cylindres, du nombre de cycles par minute, du nombre de stades, de la température du liquide et d'autres facteurs. D'autre part, on sait également que, pour les pompes à piston à commande manuelle, la hauteur d'aspiration est délimitée par la pression barométrique et par les résistances passives à un maximun d'environ 7-8 m tandis que la portée en volume de ces pompes est limitée à un maximum d' en viron 500-600 1/h.Consequently, the range and the height of elevation of these pumps of known type depend on the control force adopted, the dimension and the number of cylinders, the number of cycles per minute, the number of stages, the temperature of the liquid and other factors. On the other hand, it is also known that, for manually operated piston pumps, the suction height is limited by the barometric pressure and by the passive resistances to a maximum of approximately 7-8 m while the range in volume of these pumps is limited to a maximum of around 500-600 l / h.

Le but de la présente invention est d'accroitre la hauteur d'élévation et la portée desdites pompes hy drauliques à piston en utilisant une faible puissan ce de commande, telle la commande manuelle.The object of the present invention is to increase the elevation height and the range of said hydraulic piston pumps using a low power that of control, such as manual control.

On est parvenu à ce résultat conformément à l'inven tion en adoptant l'idée consistant à appliquer à une pompe à piston submergée une transmission hydro dynamique en circuit fermé.This was achieved in accordance with the invention by adopting the idea of applying to a submerged piston pump a hydro dynamic transmission in a closed circuit.

L'invention, telle qu'elle est caractérisée dans les revendications énoncées ci-dessous, permet d'ob tenir les résultats suivants: l' aspiration d'eau ou d'autres liquides se trouvant meme à grande profondeur (jusqu'à 100 m et au-delà), avec une portée élevée (jusqu'à 5000 1/h) et une force de commande très réduite (≤ 2HP)The invention, as characterized in the claims set out below, allows the following results to be obtained: the suction of water or other liquids even at great depths (up to 100 m and beyond), with a high range (up to 5000 1 / h) and a very reduced control force (≤ 2HP)

Les avantages obtenus grace à la présente invention consistent essentiellement en ce que toutes les com posantes de la pompe peuvent etre trouvées dans la commerce; en ce que sa construction est simple, rapide et économique; en ce qu'il est possible de l' installer avec les méthodes ordinaires et tradition nelles utilisées pour les forages; en ce que le cout d'exercice est fort réduit; en ce qu'elle peut etre manoeuvrée facilement meme par du personnel non qualifié; en ce qu'elle reste très fiable meme après de longues périodes de fonctionnement.The advantages obtained thanks to the present invention consist essentially in that all the components of the pump can be found commercially; in that its construction is simple, rapid and economical; in that it is possible to install it with the ordinary and traditional methods used for drilling; in that the cost of exercise is greatly reduced; in that it can be easily operated even by unqualified personnel; in that it remains very reliable even after long periods of operation.

Dans l'ensemble, ladite pompe se distingue par ses prestations élevées, c'est-à-dire une hauteur d'élé vation et une portée de loin supérieures à celles obtenues, jusqu'à présent, à parité de force de com mande, et par la simplicité de son fonctionnement.On the whole, said pump is distinguished by its high performance, that is to say a height of elevation and a range far greater than those obtained, until now, at the same force as the control, and by the simplicity of its operation.
