Definitions

  • the invention relates to a feed pump with at least one driven, impeller rotating in a pump housing, with several at least one end face of the impeller arranged rings of Vane chambers, with the wreaths of the vane chambers in the wall of the pump housing arranged opposite delivery channels and with the blade chambers delimiting tangentially to the impeller Vanes.
  • Such delivery pumps are used to deliver fuel from a Fuel tanks are widely used in today's motor vehicles known from practice.
  • the delivery pump known from practice has on a common impeller two concentrically enclosing each other Wreaths from vane chambers.
  • the fuel arrives at one Rotation of the impeller via an inlet channel first in the radial inner conveyor channel and then into the radially outer conveyor channel.
  • the pump has two pump stages.
  • a feed pump with two impellers is also included a wreath of shovel chambers. These wheels each form a pump stage of the feed pump.
  • a disadvantage of the known feed pumps is that they have very large noise emissions produce. The noise emissions add up an annoying whistle.
  • the invention is based on the problem of a feed pump of the beginning mentioned type in such a way that it is a particularly little distracting Noise emission generated.
  • Randomly generated overlays by varying the angular distances of noise emissions from two rings of the guide vanes according to another advantageous development of the invention avoid if the number of vanes of different wreaths varied.
  • the feed pump according to the invention has low disturbing noise emissions a particularly high efficiency if the number the guide vanes of two concentrically enclosing rings in the radially inner rim is smaller than in the radially outer rim.
  • the a delivery channel to one arranged inside the fuel tank Guide the suction jet pump while the other delivery channel connects with a leading to an internal combustion engine of the motor vehicle Flow line is provided.
  • the one delivery channel for suction directly from the fuel tank and the other Delivery channel can be provided for suction from a swirl pot. This causes the flow of fuel from one ring of guide vanes prevented on another wreath and thus the transfer and Noise amplification within the feed pump avoided.
  • the feed pump according to the invention has particularly low noise emissions at high efficiency when the angular distances of the Guide vanes of two concentrically enclosing rings in the radially outer rim to each other vary in the range from 8 ° to 12 °.
  • Feed pump helps when the angular spacing of the guide vanes two concentrically surrounding wreaths in the inner outer rim to each other vary in the range of 16 ° to 20 °.
  • FIG. 1 shows a sectional view through a side channel pump trained feed pump.
  • the feed pump has a shaft 1 attached, rotatable between two fixed housing parts 2, 3 Impeller 4 on.
  • the feed pump has two concentrically enclosing ones Delivery chambers 5, 6.
  • the delivery chambers 5, 6 each extend from an inlet channel 7, 8 to an outlet channel 9, 10 and set each in conveying channels arranged in the housing parts 2, 3 11, 12 and arranged in the impeller 4 and of blades 13, 14 delimited vane chambers 15, 16 together.
  • the Vane chambers 15, 16 are each as a depression in one of the end faces arranged. Opposing vane chambers 15, 16 are interconnected.
  • Figure 2 shows a sectional view through the feed pump of Figure 1 along the line II - II a plan view of one of the end faces of the impeller 4. It can be seen that a total of two rings of the blade combs 15, 16 are arranged in the impeller 4. The wreaths of the blade combs 15, 16 surround one another concentrically. Furthermore, the angular distances ⁇ and ⁇ of the moving blades 13, 14 from one another are shown in FIG. The angular distances ⁇ of the guide vanes 13 of the inner ring vary between 16 ° and 20 °. A stochastic distribution of the angular distances ⁇ 1 to ⁇ 20 is given as an example for 20 blades of the radially inner ring of the guide blades 13.
  • angle angular distance angle angular distance angle angular distance angle angular distance ⁇ 1 19 ° ⁇ 9 18 ° ⁇ 17 18 ° ⁇ 2 19 ° ⁇ 10 17 ° ⁇ 18 20 ° ⁇ 3 18 ° ⁇ 11 19 ° ⁇ 19 17 ° ⁇ 4 18 ° ⁇ 12 16 ° ⁇ 20 18 ° ⁇ 5 16 ° ⁇ 13 18 ° ⁇ 21 16 ° ⁇ 6 18 ° ⁇ 14 20 ° ⁇ 22 18 ° ⁇ 7 16 ° ⁇ 15 20 ° ⁇ 23 17 ° ⁇ 8 17 ° ⁇ 16 18 °
  • the radially outer rim has 36 blades 14.
  • the angular distances ⁇ 1 to ⁇ 36 of the blades 14 to one another vary analogously to that for the radially inner rim stochastic distribution in the Range between 8 ° and 12 °.
