Title (EN) FLEXIBLE FLOATING RING SEAL ARRANGEMENT FOR ROTODYNAMIC PUMPS
(FR) ARRANGEMENT DE JOINT ANNULAIRE FLOTTANT FLEXIBLE POUR POMPES ROTODYNAMIQUES
Abstract: front page image
(EN)A floating ring seal arrangement for rotodynamic pumps comprises a flexible ring that is structured to fit within a circular channel formed by generally concentric grooves in the rotating and non-rotating elements of the pump, the ring further being sized to rest against the inner diameter of the groove of the rotating element when static, and capable of radially expansion under centrifugal forces to cause the flexible ring to float in the circular channel during operation of the pump, or deformation under centrifugal or pressure forces such that gaps between the flexible ring and groove in the non-rotating element are minimized or eliminated.
(FR)Arrangement de joint annulaire flottant pour pompes rotodynamiques comprenant un anneau flexible structuré pour s'adapter dans un canal circulaire formé par des gorges sensiblement concentriques dans les éléments rotatifs et non rotatifs de la pompe, l'anneau étant en outre dimensionné pour reposer contre le diamètre intérieur de la gorge de l'élément rotatif lorsqu'il est statique, et capable d'une expansion radiale sous l'effet de forces centrifuges pour provoquer le flottement de l'anneau flexible dans le canal circulaire durant le fonctionnement de la pompe, ou d'une déformation, sous l'effet de forces centrifuges ou de pression, telle que les espaces entre l'anneau flexible et la gorge dans l'élément non-rotatif soient minimisés ou éliminés.
