Title (EN) SEAL FLOW AND PRESSURE CONTROL
(FR) RÉGULATION DE DÉBIT ET DE PRESSION DE JOINT D'ÉTANCHÉITÉ
Abstract:
(EN) Apparatus and methods for decreasing pressure of drilling fluid within a region between an impeller and a housing of a power generation module (PGM). The apparatus comprises a shaft extending from and rotatable relative to the housing; The impeller is coupled with the shaft external to the housing and includes a group of blades that rotate the impeller as the drilling fluid flows past the PGM. The impeller further includes another group of blades that decrease the pressure of the drilling fluid within the region between the impeller and the housing when the impeller is rotating.
(FR) Cette invention concerne un appareil et des procédés de réduction de la pression du fluide de forage au sein d'une région entre une roue et un boîtier d'un module de génération d'énergie (PGM). L'appareil comprend un arbre s'étendant à partir du boîtier et apte à tourner par rapport à celui-ci. La roue est reliée à l'arbre à l'extérieur du boîtier et comprend un ensemble d'aubes qui entraînent la roue en rotation à mesure que que le fluide de forage s'écoule à travers le module de génération d'énergie. La roue comprend en outre un autre ensemble d'aubes qui réduisent la pression du fluide de forage au sein de la région entre la roue et le boîtier lorsque la roue est en rotation.
