Definitions

  • the invention relates to a feed pump with a driven impeller rotating in a pump housing, with at least one ring of vane chambers, with a partially annular channel arranged opposite the ring of the vane chamber in the wall of the pump housing and extending from an inlet channel to an outlet channel, the cross section of the partially annular channel has several sections.
  • Such feed pumps are often used as fuel pumps and are known in practice.
  • the delivery chamber composed of the partially annular channel and the blade chambers is to be adapted to the circulation flow generated therein.
  • at least one of the sections has a surface, so that the circulation flow has an alternating distance from the wall of the partially annular channel.
  • a disadvantage of the known feed pump is that vortices occur at the transitions of the sections and thus in the areas in which the circulation flow is at a particularly large distance from the wall of the partially annular channel, which lead to a sharp reduction in the efficiency of the feed pump.
  • the cross section of the delivery chamber in a delivery pump known from EP 0 646 727 B1 is designed as part of an ellipse, the depth of the partially annular channel being less than half is the minor axis of the ellipse.
  • This avoids flat sections in the region of the delivery chamber.
  • a disadvantage of this feed pump is that turbulence occurs in the inlet area and in the outlet area of the circulation flow in the partially annular channel, since the delivery chamber forms tapering pockets, particularly in areas adjacent to the vane chamber, and the circulation flow is therefore at a variable distance from the wall of the partially annular channel.
  • the elliptical design of the cross section of the partially annular channel is very difficult to manufacture.
  • the invention is based on the problem of designing a feed pump of the type mentioned at the outset in such a way that eddies in the partially annular channel are avoided and that the feed pump has a particularly high degree of efficiency.
  • each of the sections is formed by a radius.
  • the delivery chamber can be easily adapted to the circulation flow of the medium to be delivered and its viscosity. Changing distances between the circulation flow can easily be avoided. Turbulence within the feed pump is therefore reliably avoided.
  • the feed pump according to the invention therefore has a particularly high efficiency. Another advantage of this design is that the optimum efficiency can be placed on the operating point of the feed pump by a suitable choice of the radii and the sections.
  • the feed pump according to the invention can be manufactured particularly inexpensively by a total of three to five sections.
  • FIG. 1 shows a sectional view through a feed pump according to the invention
  • FIG. 2 shows a greatly enlarged partial section in the region of a delivery chamber of the delivery pump from FIG. 1, 3, 4 further embodiments of the feed chamber of the feed pump in partial section.
  • FIG. 1 shows a feed pump 2, which is driven by an electric motor 1 and is designed as a side channel pump.
  • a feed pump 2 can be used, for example, to deliver fuel in a motor vehicle today.
  • the feed pump 2 has an impeller 6 driven between two housing parts 3, 4 of a pump housing 5.
  • the impeller 6 is fastened on a shaft 7 of the electric motor 1.
  • the housing parts 3, 4 of the pump housing 5 are kept at a distance by means of an annular spacer 8.
  • the impeller 6 has a ring of blade chambers 9 in its end faces. In the regions of the housing parts 3, 4 opposite the rings of the blade chambers 9 there are partially annular channels
  • the vane chambers 9 and the part-ring-shaped channels 10 form delivery chambers 13 extending from an inlet channel 11 to an outlet channel 12 of the feed pump 2.
  • a medium becomes through the inlet channel
  • FIG. 2 shows, in a greatly enlarged illustration, a cross section of one of the delivery chambers 13 from FIG. 1.
  • the blade chambers 9 in the impeller 6 have an approximately semicircular or semi-elliptical cross section.
  • the cross section of the partially annular channel 10 has three sections 14-16 each having a radius R 2 ', R 2 ''.
  • the origin of the two outer radii R 2 ' is located on the end face of the housing part 3, while the origin of the central radius R 2 '' on the vertical the end of the housing part 3 is the axis of symmetry of the partially annular channel 10.
  • the sections 14-16 each have a common tangent at their adjoining regions.
  • the two outer radii R 2 ' have approximately the radius 1.4 length units, while the mean radius R 2 ''is 1.6.
  • FIG. 3 shows a further embodiment of the delivery chamber 13 from FIG. 1 in cross section, which differs from that from FIG. 2 in that the radii R 3 'of the two outer sections 14, 16 are each 0.3 length units, while the central section 15 has a radius R 3 '' of 8 length units.
  • FIG. 4 also shows a further embodiment of the delivery chamber 13 from FIG. 1 in cross section, in which the radii R 'of the outer sections 14, 16 are each 10 length units and the middle section 15 has a radius R 4 ''of 1.4 length units.

Abstract

L'invention concerne une pompe d'alimentation se présentant sous la forme d'une pompe regénérative. Plusieurs parties (14 - 16) de cette pompe, formant la section transversale d'une chambre de refoulement (13), présentent respectivement un rayon. L'origine des rayons extérieurs est située sur la face d'un corps de pompe, orientée vers un rotor. Dans leurs zones adjacentes, les parties (14 - 16) possèdent des tangentes communes. Cette pompe d'alimentation présente ainsi un rendement particulièrement élevé.
