Title (EN) VACUUM-ASSISTED-PUMPING SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE POMPAGE SOUS VIDE
Abstract:
(EN) A system for removing a volume of liquid including a pressure-sealed-pump- vessel, at least one liquid-aperture, a liquid-level-control-valve, a liquid-discharge, a sump- pump, a pressure-sealed-suction-vessel, and one or more vessel-connections. The one or more vessel-connections configured to fluidly couple the pressure-sealed-pump-vessel and the pressure-sealed-suction-vessel, in the preferred embodiment. The sump-pump is located within the pressure-sealed-pump-vessel and includes a pump-inlet and a pump-outlet. The pump-inlet fluidly coupled to the liquid-aperture, and the pump-outlet is fluidly coupled to the liquid-discharge. The sump-pump configured to pump the volume of liquid from the pressure-sealed-pump-vessel and from the system via the liquid-discharge to remove the volume of water from a roof surface or other similar horizontal or substantially horizontal surface.
(FR) L'invention porte sur un système destiné à évacuer un volume de liquide comprenant un récipient de pompe sous pression, au moins une ouverture de liquide, une soupape de commande de niveau de liquide, une sortie de liquide, une pompe de puisard, un récipient d'aspiration sous pression et un ou plusieurs raccordements de récipient. Dans le mode de réalisation préféré, le ou les raccordements de récipient sont conçus pour accoupler fluidiquement le récipient de pompe sous pression et le récipient d'aspiration sous pression. La pompe de puisard est située à l'intérieur du récipient de pompe sous pression et comprend un orifice d'entrée de pompe et un orifice de sortie de pompe. L'entrée de pompe est accouplée fluidiquement à l'ouverture de liquide, et la sortie de pompe est accouplée fluidiquement à la sortie de liquide. La pompe de puisard est conçue pour pomper le volume de liquide à partir du récipient de pompe sous pression et du système par l'intermédiaire de la sortie de liquide pour retirer le volume d'eau d'une surface de toit ou d'une autre surface horizontale ou sensiblement horizontale similaire.
