Definitions
- the invention relates to a feed pump with at least one driven impeller rotating in a pump housing, with a plurality of rings of vane chambers arranged on at least one end face of the impeller, with the rings of the vane chambers in the wall of the pump housing arranged opposite delivery channels and with the vane chambers each tangential to Impeller limiting vanes.
- Delivery pumps of this type are frequently used to deliver fuel from a fuel tank in today's motor vehicles and are known from practice.
- the feed pump known from practice has two rings of vane chambers concentrically enclosing each other on a common impeller. When the impeller rotates, the fuel first reaches the radially inner delivery channel via an inlet channel and then the radially outer delivery channel. As a result, the pump has two pump stages.
- a disadvantage of the known feed pumps is that they produce very large noise emissions.
- the noise emissions add up to an annoying whistle.
- 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 produces particularly little disturbing noise emission.
- the noise emissions at each of the ring of the guide vanes are kept particularly low by varying their angular distances from one another. Therefore, no whistling sound is generated from any of the wreaths of the guide vanes.
- the variation in the angular spacing of the guide vanes of the various rings prevents their noise emissions from adding up. Therefore, the rings of the guide vanes each generate noise emissions at different frequencies.
- the noise emissions of the feed pump according to the invention are distributed over a large range of the audible frequency spectrum and are perceived by the human ear as uniform noise. As a result, the feed pump according to the invention produces particularly little disturbing noise emissions.
- the invention contributes to the particularly broad distribution of the noise emissions on the audible frequency spectrum if the angular spacings of the guide vanes of different rings vary in different areas.
- the feed pump according to the invention has a particularly high efficiency with low disturbing noise emissions if the number of guide vanes of two concentrically surrounding rings is smaller in the radially inner ring than in the radially outer ring.
- one feed channel can lead to a suction jet pump arranged inside the fuel tank, while the other feed channel is provided for connection to a flow line leading to an internal combustion engine of the motor vehicle.
- one delivery channel can be provided for suction directly from the fuel tank and the other delivery channel for suction can be provided from a swirl pot.
- the feed pump according to the invention has particularly low noise emissions with a high degree of efficiency if the angular spacings of the guide vanes of two concentrically surrounding rings in the radially outer ring vary in the range from 8 ° to 12 °. It contributes to a further reduction in the noise emissions of the feed pump according to the invention if the angular spacings of the guide vanes of two concentrically enclosing rings in the inner outer ring vary in the range from 16 ° to 20 °.
- FIG. 1 shows a sectional view through a feed pump according to the invention
- Figure 2 is a sectional view through the feed pump of Figure 1 along the line II - II.
- FIG. 1 shows a sectional view through a feed pump designed as a side channel pump.
- the feed pump has an impeller 4 fastened on a shaft 1 and rotatable between two fixed housing parts 2, 3.
- the feed pump has two concentrically surrounding delivery chambers 5, 6.
- the delivery chambers 5, 6 each extend from an inlet channel 7, 8 to an outlet channel 9, 10 and are each made up of delivery channels 11, 12 arranged in the housing parts 2, 3 and together in the impeller 4 and delimited by blades 13, 14 vane chambers 15, 16 together.
- the blade chambers 15, 16 are each arranged as a depression in one of the end faces. 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 chambers 15, 16 are arranged in the impeller 4. The rings of the vane chambers 15, 16 surround one another concentrically.
- Figure 3 the angular distances and ß of the blades 13, 14 to each other are shown.
- 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.
- the radially outer rim has 36 blades 14.
- the angular distances ⁇ 1 to ⁇ 36 of the blades 14 to one another vary analogously to the stochastic distribution indicated for the radially inner ring in the range between 8 ° and 12 °.
