Title (EN) POSITIVE DISPLACEMENT PUMP WITH IMPELLER AND METHOD OF MANUFACTURING
(FR) POMPE VOLUMÉTRIQUE À ROUE ET PROCÉDÉ DE FABRICATION
Abstract:
(EN) A rotary positive displacement pump (1) includes an impeller (3) that defines, within a pumping chamber (20), a plurality of successive chambers (21) with variable volume through which a fluid is mechanically conveyed from an inlet (7) to an outlet (8). The chambers (21) with variable volume are defined, at axially opposite ends, by a pair of rotational surfaces (40, 50) that close the pumping chamber (20) and are arranged to rotate about mutually inclined axes. The invention also concerns the method of manufacturing the pump.
(FR) L'invention concerne une pompe volumétrique rotative (1) comprenant une roue (3) qui définit, à l'intérieur d'une chambre de pompage (20), une pluralité de chambres successives (21) à volume variable au travers desquelles un fluide est transporté mécaniquement d'une entrée (7) à une sortie (8). Les chambres (21) à volume variable sont définies, à des extrémités opposées dans le sens axial, par une paire de surfaces rotatives (40, 50) qui ferment la chambre de pompage (20) et sont arrangées pour tourner autour d'axes inclinés mutuellement. L'invention concerne également le procédé de fabrication de la pompe.
