(FR) TECHNIQUE SOUS-MARINE FAVORISANT L'ÉCOULEMENT HYDRAULIQUE
Abstract
(EN)
The present application is directed to a submersible pumping system operable under hydrostatic pressure. The system suitably comprises a prime mover submersible within a first fluid; a pump means submersible within the first fluid and sealably coupled to the prime mover; and a fluid source in fluid communication with the prime mover, the fluid source providing a second fluid effective to act on the prime mover to power the pump means; wherein the second fluid is discharged in the first fluid after acting on the prime mover; and wherein the second fluid has a chemical composition substantially similar to the first fluid.
(FR)
La présente invention concerne un système de pompage immergé actionnable sous pression hydrostatique. Le système comprend un moteur principal immergé dans un premier fluide ; un moyen de pompage immergé dans le premier fluide et raccordé de manière étanche au moteur principal ; et une source de fluide en communication fluidique avec le moteur principal, la source de fluide permettant à un second fluide d'agir sur le moteur principal pour alimenter le moyen de pompage ; le second fluide est évacué dans le premier fluide après avoir agi sur le moteur principal ; le second fluide présentant une composition chimique sensiblement similaire au premier fluide.
