Title (EN) CENTRIFUGAL PUMP AND RADIAL IMPELLER THEREFOR
(FR) POMPE CENTRIFUGE ET HÉLICE RADIALE ASSOCIÉE
Abstract:
(EN) A centrifugal pump with a radial impeller having a first and second body portions and a plurality of impeller blades. The impeller blades are spaced circumferentially about the rotary axis and cooperate with the first and second body portions to define a plurality of flow channels. Each of the impeller blades has an axial leading edge and an axial trailing edge. At least a portion of each of the impeller blades has a rake that is contoured along the rotary axis of the radial impeller such that the axial trailing edge is offset in the first circumferential direction from the axial leading edge at meridional points along the portion of the impeller blade having the rake. A method for forming a radial impeller is also provided.
(FR) L'invention concerne une pompe centrifuge avec une hélice radiale ayant des première et seconde parties de corps et une pluralité de pales d'hélice. Les pales d'hélice sont espacées de façon périphérique autour de l'axe de rotation et coopèrent avec les première et seconde parties de corps pour définir une pluralité de canaux d'écoulement. Chacune des pales d'hélice a un bord d'attaque axial et un bord de fuite axial. Au moins une partie de chacune des pales d'hélice a un angle d'inclinaison qui est conformé le long de l'axe de rotation de l'hélice radiale de telle sorte que le bord de fuite axial est décalé dans la première direction périphérique à partir du bord d'attaque axial en des points de méridien le long de la partie de pale d'hélice ayant l'angle d'inclinaison. L'invention concerne également un procédé permettant de former une hélice radiale.
