Definitions

  • At least one axially projecting stop is arranged on the upper housing part, preferably on a retaining web, on which one of the undercuts at the end of the relative rotation of the housing pot and required for locking
  • FIG. 1 is a perspective view of a water pump
  • FIG. 4 only the groove 181 formed in the housing lower part 12 of the pressure spiral 18 can be seen, which is covered by the groove 182 of the pressure spiral 18 of the same design in the housing upper part 13, the pressure-side outlet connection 17 covering the one Half of the outlet opening 171 forming the mouth of the lower groove 181 of the pressure spiral 18 pushes.
  • a pump wheel 19 is arranged coaxially with the axis of the pump housing 11 and is seated in a rotationally fixed manner on an output shaft 20 of an electric motor 21 projecting coaxially into the pump housing 11. The rotating pump wheel 19 sucks water axially through the suction port 16 and conveys this into the pressure spiral 18, from which the water flows out via the outlet port 17 at the delivery pressure.
  • the housing pot 26 has in its pot bottom 262 (FIG. 2) an elongated hole 29 which extends in the circumferential direction and through which the winding connections 24, 25 of the stator winding 23 are passed.
  • an electronics housing is placed on the pot bottom 261, which covers the elongated hole 29 and the control electronics to be connected to the winding connections 24, 25, e.g. for speed control, for the electric motor 21 contains.
  • the water pump is installed as follows:

Abstract

La présente invention concerne une pompe à liquides, notamment une pompe à eau, présentant un boîtier de pompe (11) entourant une roue de pompe, et un boîtier de moteur relié à ceux-ci, dans lequel se trouve un moteur électrique (21) doté d'un stator (22) et d'un rotor, qui entraîne la roue de pompe. Afin de garantir l'étanchéité de la pompe contre les fuites de liquide et l'étanchéité du boîtier de moteur contre la pénétration de liquide, au moyen d'un élément d'étanchéité unique, et de permettre l'assemblage de la pompe à liquides sans élément de liaison supplémentaire, le boîtier de pompe (11) présente une partie inférieure de boîtier (12) dotée d'une bride annulaire (14) s'éloignant radialement vers l'extérieur, et une partie supérieure de boîtier (13) qui est insérée sur la partie inférieure de boîtier (12). Entre l'extrémité faciale annulaire libre de la partie supérieure de boîtier (13) et la bride annulaire (14) se trouve un anneau d'étanchéité (15). Le boîtier de moteur se présente sous la forme d'un boîtier cupuliforme (26) qui recouvre avec un bord de recouvrement (28) la bride annulaire (14), l'anneau d'étanchéité (15) et partiellement la partie supérieure de boîtier (13), et s'enclenche avec la partie supérieure de boîtier (13) grâce à la production d'une force de serrage axiale.
