Title (EN) METHOD OF COUPLING STATOR/ROTOR LAMINATES
(FR) PROCÉDÉ DE COUPLAGE DE STRATIFIÉS DE STATOR/ROTOR
Abstract:
(EN) A stator assembly (3) for a progressing cavity pump (10) is provided. The stator assembly (3) includes a number of stator laminates (101) having a planar body (110) defining a primary, inner passage (114) and a number of outer passages (116), the outer passages (116) disposed effectively adjacent the inner passage (114) whereby the inner passage (114) is at least partially defined by a band (180, 182), wherein the band (180, 182) is outwardly flexible. The stator laminates (101) are coupled to each other in a stack (99) wherein the stator laminate body inner passages (114) define a helical passage (104). The helical passage is a flexible helical passage (104).
(FR) La présente invention concerne un ensemble stator (3) pour une pompe volumétrique (10) à vis excentrée. L'ensemble stator (3) comprend un certain nombre de stratifiés de stator (101) possédant un corps plan (110) définissant un passage interne primaire (114) et un certain nombre de passages externes (116), les passages externes (116) étant disposés de façon à être efficacement adjacents au passage interne (114), le passage interne (114) étant au moins partiellement défini par une bande (180, 182), la bande (180, 182) étant flexible vers l'extérieur. Les stratifiés de stator (101) sont couplés les uns aux autres sous la forme d’un empilement (99), les passages internes (114) du corps de stratifié de stator définissant un passage hélicoïdal (104). Le passage hélicoïdal est un passage hélicoïdal flexible (104).
