Abstract

Cette pompe centrifuge du type radial comprend un rotor à aubes formant des passages entre un orifice central et une chambre collectrice dont la section transversale augmente dans le sens d'écoulement vers l'orifice de sortie, ce rotor s'étendant sur la circonférence de la chambre collectrice. Une partie 12B de la chambre collectrice est située sur le côté du rotor, à l'intérieur de la périphérie Il de celui-ci en direction radiale et les passages 9 du rotor 3 sont ouverts en direction axiale vers ladite partie 12B de la chambre collectrice. La fabrication de cette pompe est simplifiée et son rendement amélioré.This radial-type centrifugal pump comprises a vane rotor forming passages between a central orifice and a collecting chamber, the cross section of which increases in the direction of flow towards the outlet orifice, this rotor extending over the circumference of the collecting chamber. A part 12B of the collecting chamber is located on the side of the rotor, inside the periphery II thereof in the radial direction and the passages 9 of the rotor 3 are open in the axial direction towards said part 12B of the collecting chamber. . The manufacture of this pump is simplified and its efficiency improved.
