Definitions

  • the invention has the object of further developing a circulating pump of the generic type, d. H. with largely independent performance quality from the fluid system, d. H. in which there is a higher and also continuous working pressure as well as suction pressure.
  • an electrically driven pump with the characteristics described in the characterizing part of claim 1 is known (DE 10 2006 012 481 A1), belongs in the known embodiment to a completely different genus, which serves a completely different purpose. Since such pumps can generate high pressures, they are used primarily in machine tools or high-pressure hydraulic systems, such as in production automation or robots.
  • Stirnierekugelsegment and the claimed embodiments means overcoming the present in the art for circulating pumps bias regarding its expertise, ie expertise of circulating pumps for promoting a heat transfer fluid.
  • the expert of circulating pumps for the promotion of heat transfer fluids of Heating systems or solar panels always starts from the centrifugal pumps described above, although he the problems, especially in the transport of heat transfer fluid in solar panels, known.
  • the drive steeply and / or driven down steeply on the side facing away from the pump chamber on a journal, wherein the bottom bearing ring-shaped has a central bearing bore for receiving the journal.
  • the pump housing may be cup-shaped according to an additional embodiment of the invention with a sloping to its central axis bottom for receiving the bottom bearing of the driven part.
  • the drive part of the pump runs in a coaxially arranged with the shaft of the electric motor plain bearing bush, which is clamped by a retaining ring to a pump inlay.
  • the circulating pump advantageously forms a unit per se, which is retained even when the electric motor 2 is removed.
  • This is an externally cylindrical formed inlay 17, which is arranged in the housing 15 fitting and in which are supported by plain bearing bushings 18 and 19, a pump driving part 20 and a Pumpenabtriebsteil 21 are arranged to rotate.
  • the pump drive member is interposed with a coupling 22 of the shaft 8 of the Electric motor driven.
  • Fig. 4 it is especially recognizable that serve for the connection for the heat transfer fluid two threads clip 27 and that for stationary attachment of the circulation pump, a mounting block 28 is arranged with an internal thread, not shown on the housing 15. All in the description, the following claims and the drawings illustrated features may be essential to each other, both individually and in any combination with each other.

Abstract

Pompe de recirculation pour le transport d'un liquide porteur de chaleur, et comportant un entraînement par un moteur électrique, par exemple pour des installations de chauffage. Elle comporte un segment sphérique à denture frontale d'entrée et un segment sphérique à denture frontale de sortie, dont les dents qui s'engrènent les unes dans les autres sont formées par des cycloïdes.
