Definitions

  • the invention relates to a feed pump with a driven, impeller rotating in a pump housing, in which one in at least one of its faces Wreath vane chambers delimiting guide vanes arranged are with one in the area of the guide vanes in the Pump housing arranged partially annular channel, which with the scoop chambers for conveying a liquid from an inlet duct to an outlet duct Delivery chamber forms.
  • Such feed pumps are peripheral or side channel pumps known and become, for example, for funding of fuel or washing fluid from a windscreen washer system a motor vehicle used. Generate here the guide vanes in the delivery chamber a cross to the direction of movement of the guide vanes circulating flow.
  • the feed pump is characterized by particularly low-maintenance operation. Continue to leave generate very high delivery pressures with the delivery pump. With such a feed pump, however, in particular volatile when flowing into the delivery chamber Liquids such as fuel evaporate or solvent of a washing liquid and so that gas bubbles form. The gas bubbles are all the more common the higher the temperature of the liquid and the lower is the pressure in the inlet duct. The gas bubbles lead to a sharp reduction in the output the feed pump. Furthermore, the gas bubbles create one Cavitation on the pump housing. This cavitation leads to Duration to destruction of the wall of the part-ring Channel and then to a reduced delivery rate the feed pump.
  • a feed pump known from practice has several Pump stages with several impellers. This could the pressure increase in the feed pump is gradual, so that evaporation of the liquid is avoided becomes.
  • this feed pump has the disadvantage that several Impellers for generating several pump stages a considerable cause constructive effort.
  • the feed pump hereby consists of a large number of components complex to align and assemble have to.
  • the invention is based on the problem of a feed pump of the type mentioned at the outset so that they largely prevents evaporation of the fuel and is as inexpensive to manufacture.
  • the feed pump seen at least two in the direction of flow has inlet channels arranged one behind the other.
  • the liquid to be pumped first divided into the inlet channels and then arrives at various points in the delivery chamber.
  • the flow through the first inlet channel is experienced Part of the liquid initially increased pressure and then with the through the second inlet duct mixed liquid entering the delivery chamber. That is why there is a strong negative pressure in the area of the inlet channels avoided and thus compared to one Feed pump with a single inlet channel the danger evaporation of the liquid is significantly reduced.
  • the feed pump according to the invention only requires one single impeller and thus consists of very few components. As a result, the feed pump according to the invention particularly inexpensive to manufacture.
  • the feed pump according to the invention is flowed through axially and is therefore particularly low Dimensions if the inlet channels in a first inlet side Housing part of the pump housing and the outlet channel in a housing part opposite the inlet side arranged on the outlet side of the housing are. With this design, the feed pump can be without complex laying of cables, for example in attach a conveyor unit for a fuel tank.
  • the length of the part-ring-shaped channel or part-ring-shaped Channels determine the diameter of the impeller and thus the radial dimensions of the feed pump.
  • the Feed pump according to the invention has particularly small radial Dimensions if at least one of the housing parts two concentrically enclosing partial rings Channels and the impeller two appropriately arranged Wreaths has vane chambers.
  • the Number of inlet channels can be according to another advantageous development of the invention is particularly low hold when one of the inlet channels in the radial inner part-annular channel and a second inlet channel opens into the outer part-ring-shaped channel and the radially inner part-annular channel with the radially outer partially annular channel is connected.
  • connection of the radially inner part-ring-shaped channel with the outer part-annular channel is designed according to another advantageous development of the invention structurally particularly simple if the radially inner Partial ring-shaped channel via one in one of the housing parts the feed pump incorporated, designed channel-like Overflow channel with the radially outer ring-shaped part Channel is connected.
  • the housing parts of the feed pump are inexpensive for example in an axially demoldable sintered mold produce.
  • Swirls in several in a single part-ring Channel-opening inlet channels can be according to another advantageous development of the invention just avoid if the part-ring shaped channels at a cross-sectional expansion for each of the inlet channels exhibit. This forms in the direction of flow seen the circulation flow after the first inlet duct out. Then the next one Inlet channel inflowing liquid from the circulation flow recorded and carried evenly.
  • FIG. 1 shows an electric motor according to the invention 1 driven, designed as a side channel pump Feed pump 2 with an inlet-side housing part 3 and an outlet-side housing part 4.
  • the housing parts 3, 4 are biased against an annular spacer 5. Between the housing parts 3, 4 is one on one Shaft 6 of the electric motor 1 attached impeller 7 rotatable arranged.
  • the inlet-side housing part 3 has two Inlet channels 8, 9, each in a partially annular Channel 10, 11 open.
  • the two ring-shaped Channels 10, 11 are arranged concentrically to one another.
  • the outlet-side housing part 4 has a single partial ring Channel 12, which opens into an outlet channel 13.
  • the partially annular channel 12 of the outlet-side housing part 4 is radial up to the range of inner partial annular channel 11 of the inlet side Housing part 3 guided overflow channel 14 connected.
  • At a rotation of the impeller 7 is a to be promoted Liquid from the two inlet channels 8, 9 to the Outlet duct 13 promoted.
  • the feed pump 2 is here flows axially.
  • the inlet-side housing part 3 from FIG. 1 is in one View seen from the impeller 7 shown in Figure 2.
  • the radially outer part-annular channel 10 and the inner part-annular channel 11 each extend over an angular range of approximately 270 ° to 320 °.
  • the inlet channels 8, 9 are each at one end of the partially annular channels 10, 11 arranged.
  • FIG. 3 shows the housing part 4 on the outlet side Figure 1 seen from the impeller 7.
  • the partial ring Channel 12 opens into the outlet channel 13.
  • At its the The end facing away from outlet duct 13 is the part-ring-shaped one Channel 12 with the channel-shaped overflow channel 14 connected.
  • the feed pump shown in Figure 1 thus has a from the in the radially inner part-annular channel 11th opening inlet channel 9 to the outlet channel 13 Delivery chamber 21 for delivering the liquid.
  • a second delivery chamber 22 extends from the radially outer partially annular channel 10 opening inlet channel 8 to the end of the radially outer part-annular Channel 10 of the inlet-side housing part 3.
  • the overflow channel 14 shown in Figure 3 ends the inlet channel 8 of the radially outer ring-shaped part Channel 10 opposite side of the impeller 7.
  • FIG. 4 shows one of the inlet channels 8 from FIG. 2 in a sectional view along the line IV - IV.
