Definitions

  • the invention relates to an impeller of a centrifugal pump with a rear support disk on which the impeller blades are arranged, permanent magnets being attached to the rear of the support disk for capturing particles contained in the delivery fluid.
  • the US2004 / 0062648 A1 discloses an impeller with an integrated magnetic disc.
  • the object of the invention is to improve an impeller of the type mentioned at the beginning in such a way that, on the one hand, it is reliably prevented that magnetizable particles get into the bearings and the motor rotor space and, on the other hand, the particles are prevented from adhering to the impeller.
  • a disk or cap is attached to the back of the impeller, in or on which the magnets are attached, and that the outer surface of the disk or cap, which faces the flow rate located on the back of the support disk, of is covered by a layer of material.
  • the material layer covering the outer surface of the disc or cap ensures that the magnetizable particles do not adhere to the magnets of the impeller, but are instead conveyed into the pump chamber by the centrifugal forces acting on the back of the impeller and thus conveyed to the pump outlet.
  • the magnets thus have a redirecting effect for the magnetizable particles, whereby it is ensured that they do not stick to the magnets and thus do not impair the efficiency of the impeller.
  • the required magnet strength depends on the gap between the impeller and the housing wall as well as the distribution on the impeller.
  • the construction should be designed in such a way that a low magnetic force is sufficient to safely discharge the particles into the pump chamber.
  • the magnets are encapsulated by the plastic of the impeller support disk.
  • the impeller is preferably an injection molded part made of plastic.
  • the magnets on the impeller are covered by a disk or a cap.
  • the cover consists of a material on which the particles can slide off easily.
  • the cover can also be formed by the injection molded part of the impeller.
  • the surface of the cover or the material is provided with a non-stick coating. It is preferably proposed here that the covering layer is a DLC coating. Optimal results are achieved when the thickness of the cover or the covering material is 0.4 to 2 mm. It is also advantageous if the distance between the rear of the impeller and the pump wall is preferably 2 to 10 mm.
  • the magnet or magnets can also be designed as a ring or segment. It is also proposed that that the magnets are arranged close to the outer diameter of the impeller, evenly distributed over the circumference of the impeller.
  • the impeller is driven by an electric motor, the rotor of which is surrounded by a can or can and around which the conveying medium flows.
  • a motor centrifugal pump has a pump housing 1, in the pump chamber of which the impeller 2 is mounted, which is fastened to the end of the shaft 3 of the wet-running electric motor.
  • the shaft 3 with its motor rotor 4 is surrounded by a can or a can 5 and the conveying medium for motor cooling flows around it.
  • a pump wall 6 separates the pump chamber from the engine compartment.
  • the impeller 2 of the pump has a rear circular support disk 7 made of plastic, on the front side of which the impeller blades 8 are integrally formed in order to convey the pumped liquid reaching the impeller center from the suction channel 9 into the pressure channel 10.
  • the magnetic force acting on the particles has the effect that the particles striving towards the center (shaft) due to the impeller side space flow are deflected by these magnets on the rear of the impeller to the rear wall of the impeller and are pushed back into the pump chamber by the centrifugal force acting here without the motor rotor space within the To reach containment shell or can and without getting into the camp.
  • the magnets can be designed differently, for. B. as a ring, individual magnets or segments.
  • the magnets 12 are encapsulated by the plastic of the support disk 7, so that the impeller is an injection-molded part, the plastic of which covers the magnets 12 by 0.4 to 2 mm.
  • the cover of the magnets 12 is formed by a 0.4 to 2 mm thick rear wall 13 which is attached to the rear of the impeller 2 and is preferably made of plastic.
  • the overlap or the cover can consist of a material on which the particles slide easily.
  • the outer surface of the magnet cover, in particular the additional rear wall 13 is provided with a non-stick coating, in particular with a DLC coating (amorphous carbon layer), so that the particles do not adhere to the rear of the impeller with greater certainty.
  • a non-stick coating in particular with a DLC coating (amorphous carbon layer), so that the particles do not adhere to the rear of the impeller with greater certainty.
  • the distance between the rear of the impeller and the pump wall 6 is preferably 2 to 10 mm. Furthermore, the magnetic flux density of the magnets 12 is preferably 0.02 to 0.2 Tesla.
  • the magnets are fastened in or on the disk 13 or cap which is fastened to the rear of the impeller.
  • the outer surface of the disk or cap is covered by an in particular non-magnetic material. Otherwise, the same applies to the execution. technical characteristics.
