Abstract

Une pompe hydraulique à piston, submergée, où le mouvement vertical alternatif du piston (20) est obtenu au moyen d'un cylindre opérateur (4), lequel est placé au som­ met de la pompe (2) et a son propre piston (40) qui fonctionne en tandem avec le piston (20) de la pompe (2); ce premier cylindre (4) est en outre accouplé de manière hydraulique, avec du liquide à saturation, à un cylindre moteur (5), de surface, dont la tige (50) est actionnée par une roue motrice. A submerged hydraulic piston pump, where the reciprocating vertical movement of the piston (20) is obtained at by means of an operating cylinder (4), which is placed at the top puts pump (2) and has its own working piston (40) in tandem with the piston (20) of the pump (2); this first cylinder (4) is also hydraulically coupled, with saturated liquid, to a driving cylinder (5), surface, the rod (50) of which is actuated by a drive wheel.

En variant la mesure du diamètre des cylindres (4-5) par rapport à celui de la pompe (2), il est possible de commander la roue motrice avec un moteur de faible puissance (≦2 HP) ou même manuellement et de soulever jusqu'à 5000 l/h de liquide, jusqu'à 100 m de profondeur. By varying the measurement of the diameter of the cylinders (4-5) by compared to that of the pump (2), it is possible to order the driving wheel with a low power motor (≦ 2 HP) or even manually and lift up to 5000 l / h of liquid, up to 100 m deep.
