Definitions
- Peripheral pump in particular for delivering fuel from a storage tank to the internal combustion engine of a motor vehicle
- the invention relates to a peripheral pump according to the preamble of the main claim.
- a peripheral pump is already known (US Pat. No. 3,315,607), in which the common center of the two circular sections lies on the axial gap between the impeller and the chamber wall.
- US Pat. No. 3,315,607 the common center of the two circular sections lies on the axial gap between the impeller and the chamber wall.
- the efficiency of such peripheral pumps cannot be satisfactory.
- peripheral pump according to the invention with the characterizing features of the main claim has the advantage that the pump output is increased to a satisfactory level because the circulation flow Qc can be increased by approximately 20% under otherwise identical conditions. This means that the maximum delivery pressure can be increased accordingly with the same external dimensions and operating conditions.
- Advantageous further developments and improvements of the peripheral pump specified in the main claim are possible through the dimensional analogs listed in the subclaims.
- FIG. 1 shows a fuel delivery unit with a peripheral pump shown in longitudinal section
- FIG. 2 shows a detail of the peripheral pump denoted by II in FIG. 1, on an enlarged scale
- FIG. 3 shows a cross section through the peripheral pump according to FIG. 1, along the line III-III and
- FIG. 4 a graph showing the increase factor for the circulation flow as a function of ⁇ .
- FIG. 1 An assembly 10 shown in FIG. 1 is used to deliver fuel from a storage tank (not shown) to the internal combustion engine (also not shown) of a motor vehicle.
- the fuel delivery unit 10 has a flow pump 12, the impeller 14 of which is connected in a rotationally locking manner by a shaft 16 driven by an electrical drive motor (not shown).
- the impeller 14 is seated on a bearing journal 18 and is arranged in a so-called pump chamber 19 which - seen in the axial direction of the impeller 14 - is delimited on both sides by walls 20 and 22.
- the bearing pin 18 is arranged on the wall 20.
- the wall 22 has a bearing point 24 for the drive shaft 16.
- the flow pump 12 draws fuel through a suction port 26 and presses this medium via a pump outlet 28 in the wall 22 into a space 30 in which the electric motor (not shown) is accommodated. From there the fuel is supplied to the internal combustion engine via an outlet or pressure port 32. Since both the flow pump 12 and the electric motor (not shown) are accommodated in a common housing 33, which is provided with a suction port 26 and a pressure port 32 and the fuel thus flows through the fuel delivery unit 10, the fuel delivery unit forms part of the delivery line from the storage tank, as it were to the internal combustion engine.
- the impeller 14 of the flow pump 12 has a disk-shaped, central region 34 which is provided with a central bearing bush 36 in which the bearing journal 18 of the wall 20 is mounted.
- the impeller 14 or its central region 34 has a multiplicity of radial vanes 38 which are connected to one another at their free ends facing away from the central region 34 by a circumferential ring 40, which is, however, not absolutely necessary.
- the vanes 38 are formed in that 14 webs remain between openings 42 of the impeller which are arranged on a common pitch circle and which limit the openings 42 in the circumferential direction.
- the axis of each opening 42 runs parallel to the axis of rotation of the impeller.
- the gap 42 remaining between the mutually adjacent wings 38 in the circumferential direction can also be referred to as a groove.
- the bottom of its groove is particularly shaped.
- the groove base 46 extends like a circular segment. This also applies to the other side of the impeller 14, where the groove base 50 also extends from the end face 48 like a segment of a circle.
- the two circular sections 46 and 50 merge smoothly into one another in the central region of the impeller 14. Since the impeller 14 is preferably manufactured in a mold, both the groove base 46 and the groove base 50 must be guided over short, horizontal end sections 52 to the end faces 44 and 48 for reasons of better formability run parallel to the axis of rotation of the impeller. In both the groove base 46 and the groove base 50 must be guided over short, horizontal end sections 52 to the end faces 44 and 48 for reasons of better formability run parallel to the axis of rotation of the impeller. In both the groove base 46 and the groove base 50 must be guided over short, horizontal end sections 52 to the end faces 44 and 48 for reasons of better formability
- Chamber walls 20 and 22 each have an almost annular delivery channel 54 and 56.
- the bottom 58 of the conveying channel 54, as well as the bottom 60 of the conveying channel 56, are likewise shaped in the form of a circular segment.
- Both the circular sections 46 and 58 and the circular sections 50 and 60 each have common centers 62 and 64, respectively.
- the radii of each groove base 46 and 50 have been given 68 in FIG.
- the radii of each base 58, 60 of the delivery channels 54 and 56 are denoted by 66 in FIG.
- An essential feature of the invention can be seen in the fact that the centers 62 and 64 of the two circular sections 68 and 66 are the same and lie within the contour of the impeller 14 (FIG. 2). As FIG.
- the two centers 62 and 64 have each been moved into the impeller contour by a dimension 70, measured from the respective adjacent end faces 44 and 48 of the impeller 14. It is also noteworthy that the two centers 62 and 64 - based on the axis of rotation of the impeller - are arranged on a common pitch circle with a radius 72.
- the pressure of a peripheral pump can be calculated approximately according to the relevant literature using the following formula:
- A conveyor channel cross section
- ⁇ angular velocity of the impeller
- Qc or C can be calculated back from measurement results. Without measurement results, d. H. if a pump is not yet available, Qc or C can only be calculated approximately using finite elements from the geometry and the operating data. In such calculations it was found that keeping all the parameters in equation (1) and equation (2) constant, the constant C one
- Canal cross section is a circular section
- the value ⁇ is on the abscissa and the ratio of the associated C factor C ( ⁇ ) to the C factor for is on the ordinate
