Definitions
- the invention relates to a delivery pump with a driven impeller rotating in a pump housing and having at least one rim of vane chambers in its end faces, in which the vane chambers have an inflow region and an outflow region for the medium to be conveyed, and with at least one im Area of the guide vanes in the pump housing arranged partial ring, which forms with the vane chambers a delivery chamber from an inlet channel to an outlet channel, the contour of the vane chambers being formed by at least one radius with an origin within the delivery chamber
- Such delivery pumps are often used for delivering fuel in a fuel tank or for delivering washing liquid in a windscreen washer system of a motor vehicle and are known from practice.
- the known delivery pump has a ring of vane chambers in both end faces of the impeller.
- the vane chambers are in the radially outer direction from a straight wall, which is arranged perpendicular to the end faces of the impeller.
- the contour of the vane chambers pointing to the radially inner direction of the impeller is generated by a radius.
- the origin of the radius is arranged on the center line arranged perpendicular to the end faces of the impeller. This origin is also the origin of a second radius forming the part-shaped channel
- the invention is based on the problem of designing a feed pump of the type mentioned at the outset in such a way that it has the highest possible efficiency and reliably avoids the formation of vapor bubbles.
- the blade chamber has a contour that rises very flat from the end face in its area formed by the radius.
- a circulation flow in the delivery chamber alternates between the impeller and the pump housing via this flat contour. Since the circulation flow experiences only a slight deflection in this area, the risk of turbulence is kept particularly low. This also prevents the formation of vapor bubbles.
- the impeller can be manufactured inexpensively if the origins of a plurality of radii for opposing contours of the vane chambers are arranged within the impeller on a common plane running parallel to the end face of the impeller. Turbulence often occurs in the area in which the circulation flow changes between the vane chamber and the partially annular channel.
- the circulation flow swirled here can quickly calm down again if the vane chambers have boundaries running perpendicular to the end face of the impeller from the plane running parallel to the end face of the impeller to the end face in their regions adjacent to the guide vanes ,
- the impeller has simply constructed blade chambers and can therefore be manufactured particularly inexpensively if the origins of two radii, which each produce contours that are opposite one another, are arranged in mirror image of the center line of the blade chamber.
- the center line can be designed as a line of symmetry for the contour pointing to the center of the impeller and the contour pointing away from the center of the impeller.
- the feed pump according to the invention has a particularly high efficiency if the distance between the origins of the radii and the center line is approximately the same as their distance from the end face.
- Vane chambers arranged opposite one another could be connected to one another in a radially outer region of the impeller, as in the known feed pump.
- blade chambers arranged opposite one another in the two end faces of the impeller are connected to one another only in the region of the center line.
- FIG. 1 shows a sectional view through a feed pump according to the invention
- FIG. 1 shows a longitudinal section through a feed pump 2, which is driven by an electric motor 1 and is designed as an axially through-flow side channel pump and which can be provided, for example, for delivering fuel from a fuel tank (not shown) of a motor vehicle.
- the feed pump 2 has a pump housing 3, in which an impeller 5 is arranged in a rotationally fixed manner on a shaft 4 of the electric motor 1.
- the pump housing 3 has an inlet channel 6 on its side facing away from the electric motor 1 and an outlet channel 7 on the side facing the electric motor 1.
- the inlet channel 6 opens into a delivery chamber 8.
- a second delivery chamber 9 opens into the outlet channel 7.
- the delivery chambers 8, 9 each have partially annular channels 10, 11 machined in the pump housing 3 and vane chambers 12, 13 arranged in the impeller 5.
- the blade chambers 12, 13 are each delimited by guide blades 14, 15 and each have an inflow region 16, 17 for inflowing the medium to be conveyed um and an outflow area 18, 19. Vane chambers 12, 13 lying opposite one another are connected to one another between the inflow region 16, 17 and the outflow region 18, 19.
- circulation flows are produced in the delivery chambers 8, 9.
- a partial flow is branched off from the circulation flow of the inlet-side delivery chamber 8 and flows into the delivery-side delivery chamber 9.
- the currents are marked with arrows in the drawing.
- the circulation flow reaches the vane chambers 12, 13 with particularly small swirls from the partially annular channels 10, 11.
- the plane of the origins of the radii R is approximately the same distance from the end face of the impeller 5 as the origins of the radii R from the center line.
