Abstract | A centrifugal (non-positive displacement) motor pump suitable for use in a small output area with extremely small water volume, rather simple in structure, and small in size, comprising a tubular motor stator (10), a motor rotor (20) having a permanent magnet (30), formed integral with an impeller (32), and disposed inside the motor stator (10), and a pump casing (44) fixed to the opening end part of a motor casing (12) so as to cover the impeller (32), wherein a dynamic pressure bearing (54) is formed between the front face of the impeller (32) and a spiral groove (52) provided in the internal surface of the pump casing (44) opposed to the front face of the impeller (32).
L'invention concerne une pompe de moteur centrifuge (déplacement non positif) utilisée dans une petite zone de sortie avec un volume d'eau extrêmement petit, de structure plutôt simple, et de petite taille. Ladite pompe de moteur comprend un stator tubulaire (10), un rotor (20) doté d'un aimant permanent (30) formé d'une seule pièce avec une roue à ailettes (32) disposée dans ledit stator (10), et un carter de pompe (44) fixé à un carter de moteur (12) de façon à recouvrir ladite roue à ailettes (32), un palier (54) de pression dynamique étant formé entre la face avant de la roue à ailettes (32) et une rainure spiralée (52) située sur la surface intérieure du carter de pompe (44) opposée à ladite face avant de la roue à ailettes (32). |
