Title (EN) IMPROVED IMPELLER ARRANGEMENT AND PUMP
(FR) ENSEMBLE DE TURBINES ET TURBOPOMPE AMÉLIORÉS
Abstract:
(EN) The present invention relates to an improved multi-impeller arrangement and to a pump having the impeller arrangement. The impeller arrangement or impeller cluster includes at least two impellers (17, 19), each impeller having an annular back plate (16, 18) and an annular front plate (17, 19). The impellers are releasably secured together in an axially in-line series having the front plate of a first impeller (12) at one end and the back plate of a second impeller (14) at the other end. The second impeller includes an axial projection (20) which extends from its back plate, through and beyond its front plate to the first impeller. The first impeller is engaged with the projection of the second impeller such that all impellers are rotatable as an assembly.
(FR) La présente invention concerne un ensemble de turbines multiples amélioré et une pompe présentant l’ensemble de turbines. L’ensemble de turbines ou groupe de turbines comprend au moins deux turbines (17, 19), chaque turbine ayant un disque arrière annulaire (16, 18) et un disque avant annulaire (17, 19). Les turbines sont fixées l’une à l’autre de manière libérable dans un alignement axial comprenant, à une extrémité, le disque avant d’une première turbine (12) et, à l’autre extrémité, le disque arrière d’une deuxième turbine (14). La deuxième turbine comprend une saillie axiale (20) qui s’étend depuis son disque arrière, puis au travers et au-delà de son disque avant vers la première turbine. La première turbine est en prise avec la saillie de la deuxième turbine de telle sorte que toutes les turbines sont rotatives en tant qu’ensemble.
