Definitions
- the invention relates to a side channel pump with an impeller rotatably arranged in a pump housing, with an inlet channel and an outlet channel arranged in the housing, with rotor blades arranged in the impeller for conveying a liquid from the inlet channel to the outlet channel and with guide means for guiding the impeller in an axial direction and / or radial position.
- Such side channel pumps are frequently used in today's motor vehicles, in particular for conveying fuel or windshield washer fluid, and are known from practice.
- the pump housing is composed of two housing parts, which are kept at a distance by an intermediate ring with dimensions corresponding to the height of the impeller.
- the known side channel pumps often have pockets in the area between their center and the rotor blades, in which pockets a small part of the medium to be conveyed is collected.
- the impeller floats on the medium held in the pockets. Radial forces acting on the impeller are usually absorbed by the bearing of a drive shaft of an electric motor that drives the side channel pump.
- the disadvantage here is that the guide of the impeller is very inadequate and generally does not prevent the impeller from grinding against the housing.
- the side channel pump has a very low efficiency due to the friction losses that occur during grinding. Furthermore, the gap between the impeller and the pump housing in the area of the blades fluctuates due to the insufficient guidance. This leads to a further reduction in the efficiency of the side channel pump.
- the invention is based on the problem of developing a side channel pump of the type mentioned at the outset in such a way that friction losses are avoided as reliably as possible.
- This problem is solved according to the invention in that the guide means are arranged in the region of the edge of the impeller.
- the guide means only extend over a particularly small portion of the impeller.
- the liquid to be delivered has a particularly high pressure due to friction on the impeller and due to centrifugal forces. This allows large managers to be transferred to the wheel.
- the radially outer partial area can be manufactured with a particularly high degree of accuracy with little manufacturing effort. Additional components for guiding the impeller are not necessary thanks to the invention.
- the side channel pump according to the invention is also particularly cost-effective.
- the guide means could, for example, have a ring with a large number of individual runners. To further reduce the manufacturing costs of the side channel pump according to the invention, it is helpful if the guide means have at least one guide surface that is opposite a corresponding area of the housing at a specified distance.
- a gap between the region of the impeller having the rotor blades and the housing can be designed independently of a gap arranged in the region of the guide means if the guide means have a cross-sectional change arranged in the region of the edge of the impeller and if that Areas of the impeller forming cross-sectional changes are each designed as guide surfaces that face the housing at a specified distance.
- the gap which is decisive for the friction and executives of the impeller can be set to a predetermined value independently of the gap which is decisive for the characteristic curve of the feed pump in the region of the rotor blades.
- the cross-sectional change can be produced particularly inexpensively if the cross-sectional change is designed in a step-like manner.
- the impeller can be guided both axially and radially by means of a single guide surface if the cross-sectional change is designed as a chamfer.
- the cross-sectional change designed as a chamfer is able to guide the impeller sufficiently radially and axially if the guide surface is arranged at an angle of approximately 30 to 60 ° to the end face of the impeller.
- the guide means only need a single guide surface on one side.
- the gap between the impeller and the housing in the area of the rotor blades can be set to a particularly precise height if the edge has a guide surface facing each end face. This contributes to further improving the efficiency of the side channel pump according to the invention.
- cost-intensive intermediate rings to be inserted into the pump housing can be easily avoided if two housing parts which are opposite one another and surround the impeller adjoin one another in the region of the largest diameter of the impeller.
- the height of the gap can also be set with particularly small tolerances. This contributes to a further increase in the efficiency of the side channel pump according to the invention.
- the invention permits numerous embodiments. To further clarify its basic principle, two of them are shown in the drawing and are described below. This shows in
- FIG. 1 shows a longitudinal section through a side channel pump according to the invention with adjacent areas of an electric motor
- Fig. 2 shows a longitudinal section through a further embodiment of the side channel pump according to the invention.
- FIG. 1 shows a longitudinal section through a side channel pump 1 according to the invention with adjacent areas of an electric motor 2.
- the side channel pump 1 has an impeller 4 that can be rotated in a housing 3.
- the impeller 4 is arranged on a motor shaft 5 of the electric motor 2.
- the housing 3 has two spaced housing parts 6, 7 and a rolled sheet metal strip 8.
- the metal strip 8 holds the side channel pump 1 in an intended position relative to the electric motor 2.
- An inlet channel 9 is arranged in one of the housing parts 7, while the other housing part 6 has an outlet duct 10.
- the inlet channel 9 and the outlet channel 10 are each connected to partially annular channels 11, 12.
- the impeller 4 has vane chambers 15, 16 delimited by rotor blades 13, 14 in the region of the partially annular channels 11, 12.
- the housing 3 faces the impeller 4 to form sealing gaps at a short distance.
- the side channel pump 1 has guide means 17 for the radial and axial guidance of the impeller 4.
- the guide means 17 have two guide surfaces 18, 19 which are designed as a guide surface 18, 19 and extend from the central region of the edge to the end faces listed cross-sectional reductions.
- the impeller 4 is opposite the housing 3 at an intended distance.
- the housing parts 6, 7 adjoin one another in the region of the largest diameter of the impeller 4.
- the liquid to be conveyed is conveyed from the inlet channel 9 to the outlet channel 10. In doing so, rich of the blades 13, 14 a small amount of the liquid to be pumped into the gap between the impeller 4 and the housing 3.
- This liquid is conveyed into the region of the guide means 17 by friction and centrifugal forces and is generated depending on the spacing of the guide surfaces 18th , 19 from the housing 3 and the angle of the guide surfaces 18, 19 to the end faces of the impeller 4, forces in the axial and radial direction on the impeller 4.
- the guide surfaces 18, 19 are mirror images of one another.
- the guide surface 19 facing the electric motor 2 can, however, be dispensed with if a rotor of the electric motor 2 rests on the impeller 4 and thus an intended axial force is generated.
- the guide surfaces 18, 19 or the area of the housing parts 6, 7 opposite the guide surfaces 18, 19 can have coatings with emergency running properties or for reducing sliding friction or pockets known from slide bearings for receiving the liquid to be conveyed.
- FIG. 2 shows a side channel pump 20 in which the guide means 21 have an abrupt reduction in cross-section which points from the central region of the edge to the end faces of an impeller 22.
- a radial guide surface 23 and an axial guide surface 24 are each arranged on the regions adjoining the end faces.
- a housing 25 of the side channel pump has a shape corresponding to the guide surfaces 23, 24 in this area.
- the impeller 22 has axial and radial slide bearings in its radially outer region.
