Title (EN) IMPELLER ASSEMBLY FOR CENTRIFUGAL PUMPS
(FR) ENSEMBLE TURBINE POUR POMPES CENTRIFUGES
Abstract: front page image
(EN) An impeller assembly for centrifugal pumps has two disk members that have different diameters, are arranged coaxially to a rotation axis and face each other so as to form an interspace; blades are radially arranged in the interspace; the two disk members are also centrally provided with a fastening means for fastening to a transmission shaft, which rotates about the rotation axis. The particularity of the present invention resides in having contoured vanes that protrude radially from the peripheral region of the disk member that has the smallest diameter and are arranged substantially at the blades.
(FR) L'invention concerne un ensemble turbine destiné à des pompes centrifuges, comportant deux éléments de disque qui ont des diamètres différents, sont disposés de manière coaxiale par rapport à un axe de rotation et se font face mutuellement de façon à former un espace intermédiaire; des pales sont disposées radialement dans l'espace intermédiaire; les deux éléments de disque sont également pourvus au centre d'un moyen de fixation permettant de fixer un arbre de transmission, qui tourne autour de l'axe de rotation. La particularité de la présente invention réside dans le fait d'avoir des aubes profilées qui font saillie radialement à partir de la région périphérique de l'élément de disque qui possède le plus petit diamètre et qui sont disposées sensiblement au niveau des pales.
