Title (EN) PERMANENT MAGNET PUMP
(FR) POMPE À AIMANT PERMANENT
Abstract:
(EN) A combined well pump and motor (11) includes a housing (13) having an axis (15), an upstream end and a downstream end. Diffusers (35) are mounted for non-rotation in the housing, each of the diffusers having diffuser passages (41). An impeller (47) is mounted between each of the diffusers for rotation relative to the diffusers. Each of the impellers has impeller vanes (49) defining impeller passages (55). The impeller has an exterior outer wall (51) extending circumferentially around the impeller vanes, closing outer sides of each of the impeller passages. An array of magnets (57) is mounted to each of the impellers. The magnets are spaced circumferentially apart from each other around the axis at a different radial distance from the axis than the impeller vanes. A stator (17) is mounted in the housing. The stator has windings (27) for interacting with the magnets to impart rotation to the impellers.
(FR) La présente invention porte sur une pompe et un moteur de puits combinés (11) comprenant un boîtier (13) ayant un axe (15), une extrémité amont et une extrémité aval. Des diffuseurs (35) sont montés de manière non rotative dans le boîtier, chacun des diffuseurs ayant des passages de diffuseur (41). Une turbine (47) est montée entre chacun des diffuseurs pour une rotation par rapport aux diffuseurs. Chacune des turbines comporte des aubes de turbine (49) définissant des passages de turbine (55). La turbine a une paroi externe extérieure (51) s'étendant de manière circonférentielle autour des aubes de turbine, fermant des côtés externes de chacun des passages de turbine. Un réseau d'aimants (57) est monté sur chacune des turbines. Les aimants sont espacés de manière circonférentielle les uns des autres autour de l'axe à une distance radiale de l'axe différente de celle des aubes de turbine. Un stator (17) est monté dans le boîtier. Le stator comporte des enroulements (27) destinés à interagir avec les aimants afin de donner une rotation aux turbines.
