Abstract

L'invention concerne une cartouche d'étanchéité rotative, réagissant à la pression des contaminants, de type à amplification ou modification de pression de lubrifiant (10), pour pompes de puits rotatives et autres mécanismes rotatifs. Un boîtier (12) doté d'un passage soumis à la pression des contaminants, comporte un manchon rotatif de protection contre l'usure (36) soutenu par des roulements et raccordé en étanchéité au boîtier par une pluralité de joints espacés (62, 72, 74) qui définissent au moins une (66) et de préférence deux (76) ou plus de deux chambres de lubrifiant pour assurer la lubrification des roulements et l'étanchéité hydrodynamique. Des cylindres d'amplification de pression de lubrifiant (84, 136) communiquent avec leurs chambres de lubrifiant correspondantes pour l'écoulement de fluide. Des pistons (92, 140) se déplacent dans les cylindres, définissant des surfaces différentielles exposées à la pression du lubrifiant et des contaminants. La pression des contaminants agit sur les pistons et induit une pression de lubrifiant différente, de préférence supérieure, mais pouvant être inférieure à la pression des contaminants. Lorsque la pression du lubrifiant est supérieure à la pression des contaminants, un effet directionnel est induit par rapport à la pression des contaminants ou à la pression ambiante, pour réduire au minimum le risque d'infiltration de contaminants dans les chambres de lubrifiant et pour améliorer l'effet de coinçage hydrodynamique du lubrifiant dans l'interface d'étanchéité dynamique entre les joints et l'élément rotatif, permettant ainsi de prolonger la durée de vie des joints, même sous pression élevée.
