Definitions

  • the invention relates to a pump for conveying a fluid from a suction region in a delivery region, which has a housing and at least one rotatable in the housing about a rotational axis arranged rotor, which can be driven by a drive element.
  • Pumps of this type are well known in the art. They are used for example in heating systems to pump water through the heating circuit. In most cases, centrifugal pumps are used in particular for the mentioned application.
  • the invention is therefore based on the object, a pump of the type mentioned in such a way that the hydraulic efficiency can be increased, with a cost-effective manufacturing capability should exist.
  • the pump should be used advantageously, but not exclusively, in the field of heating construction.
  • the solution to this problem by the invention is characterized in that the rotor is penetrated by a bore, that in the bore a piston element is arranged, which can move in the bore longitudinal axis, and that fixed in the housing, a number of magnets or a ring magnet is arranged, wherein the magnet or the ring magnet on the piston member exerts a magnetic attraction, wherein the magnets or the ring magnet is placed in the housing or is such that upon rotation of the rotor about the axis of rotation, the piston member due to the magnetic attraction in the bore exerts an oscillating motion.
  • the magnets move the piston element during rotation of the rotor in the direction of the longitudinal axis of the bore; this oscillating movement is used to convey the fluid and pressurize it.
  • the piston element is preferably a ball.
  • the piston element is preferably a magnet or it has at least one magnet.
  • the piston element (ie preferably the ball) is preferably tolerated in the bore, that in the translational displacement of Piston member displaced in the bore fluid located in the bore out of the bore or is sucked into the bore.
  • the bore extends advantageously in the rotor perpendicular to the axis of rotation of the rotor.
  • a seal is preferably arranged or formed at two opposite points of the rotor.
  • the seal is preferably formed by a constriction between the rotor and the housing.
  • a flow channel for fluid to be sucked can be formed between the sealing points and the delivery area.
  • the magnets which control the movement of the piston member in the bore are preferably arranged along a closed cam track in the housing; Preferably, the curved path is a circular path.
  • a ring magnet can also be used.
  • the magnets or the ring magnet are or is preferably designed as a permanent magnet / e.
  • the diameter of the bore is preferably an amount between 0.05 mm and 0.3 mm, preferably between 0, 1 mm and 0.2 mm, greater than the diameter of the piston member, in particular the ball.
  • the inner surface of the bore is particularly preferably provided with a hard material layer in order to increase the wear resistance of the bore surface. It can be provided in the rotor and a plurality of, in particular offset over the circumference arranged holes in which respective piston elements are arranged.
  • the proposed design of the pump has the consequence that a much higher hydraulic efficiency can be achieved than is the case with centrifugal pumps. By the proposed displacement principle, an efficiency of up to 80% can be achieved.
  • the relatively simple structure also allows cost-effective production, so that even large lots of pumps can be produced economically.
  • FIG. 1 shows schematically a pump according to the invention, the pump being sketched in a sectional view and showing only the components which are important in connection with the invention
  • Fig. 2 shows schematically the pump of FIG. 1 during a first
  • FIG. 3 shows schematically the pump according to FIG. 1 during a second process step of the pumping operation
  • Fig. 4 shows schematically the pump of FIG. 1 during a third
  • a pump 1 is outlined, with only the relevant here essential components are shown.
  • the pump 1 works according to the displacement principle. It has a housing 4 which extends in a conveying direction F, in which a fluid, for. As water is promoted. In this case, the housing 4 extends substantially from a suction region 2 to a delivery region. In the suction area 2, fluid is sucked into the pump 1 and pressurized, the fluid then being discharged in the discharge area 3 under increased pressure.
  • the central component of the pump 1 is a rotor 6, which can rotate about an axis of rotation 5, which is perpendicular to the plane in the figures. Not shown is a motor with which the rotor 6 can be rotated.
  • the rotor 6 has a through hole 7, which extends transversely and centrally through the rotor 6 and which is perpendicular to the axis of rotation 5. Accordingly, the bore 7 extends in the direction of the bore longitudinal axis L.
  • a piston member 8 is arranged in the form of a ball.
  • a permanent magnet is integrated in the ball 8 in the ball 8.
  • the circular diameter of this circular path is about half the diameter of the rotor 6.
  • the magnets 9, 9 ', 9 ", ... are - like the ball 8 - designed as permanent magnets.
  • the magnets 9, 9 ', 9 ", ... exert on the ball 8 a magnetic attraction, ie the ball 8 is attracted by the magnets 9, 9', 9", ....
  • the magnet 8, 9 ', 9 ", ... which is closest to the ball 8, exercises the dominant attractive force.
  • the rotor 6 has in its uppermost and lowermost region only a small distance from the wall of the housing 4, which is shown greatly exaggerated in Fig. 1. Therefore, there is a sealing gap 10 or 1 1 at the two locations mentioned, so that hardly any fluid can flow from the intake area 2 to the discharge area 3 here. Rather, the sites marked 10 and 11 are to be regarded as sealed sites.
  • FIG. 1 The total of 16 discrete magnets 9, 9 ', 9 ",..., To be recognized in FIG. 1 are not shown in FIGS. 2 to 5 for the sake of clarity, but only the circular path 14 along which the magnets 9, 9', 9 ", ... are arranged.
  • the rotor 6 is shown in FIG. 2 in a starting position, ie the bore 7 extends in the longitudinal direction of the pump 1 from the intake 2 to the delivery area 3.
  • the ball 8 closes the bore 7, the ball 8 from the next magnet.
  • 9 * (see Fig. 1) is tightened and held in position due to the magnetic force.
  • the rotor is driven counterclockwise by the drive means, not shown.
  • FIG. 3 shows, for a second process status, that the rotor 6 has been rotated by the angle in comparison to the basic position according to FIG. 2.
  • the magnets 9, 9 ', 9 ", ... pulled the ball 8 further in the direction of the bore longitudinal axis L, so that now a translational displacement x (see FIG L, which is located in the region of the bore above the ball 8, is therefore pushed out in the direction of the discharge area 3, while the growing volume of the bore 7 between the bottom left entry into the bore 7 and the ball 8 fluid from the intake 2 is sucked into the bore 7.
  • the flow of fluid is indicated by arrows.
  • FIG. 4 for a third process status upon rotation of the rotor 6 with respect to the initial position shown in FIG. 2 by the angle ß - the ball 8 of the magnets 9, 9 ', 9 ", ... in the direction Hole end pulled until in the position shown in Fig. 4, the magnet 9 ** (see Fig. 1) holds the ball 8 in position.
  • the oscillation frequency of the ball 8 in the bore 7 corresponds to twice the rotational frequency of the rotor 6.
  • the cylindrical inner surface of the bore 7 is provided with a hard material layer, so that there is a high abrasion resistance.
  • a magnet of rare earth is arranged in the embodiment.
  • discrete magnets 9, 9 ', 9 ", ... are provided, and of course a ring magnet can also be used.
  • the use of a ring magnet can prove more favorable and in particular make the guiding properties of the piston element more uniform.
