Definitions

  • the invention relates to a pump having a magnetic coupling, comprising a rotor shaft rotatably mounted in a pump housing, which carries an impeller or a spindle for conveying a fluid from a suction chamber into a pressure chamber and a rotor arranged in a split pot through which the fluid flows with an internal magnet. which can be set in rotation via the magnetic field of an external magnet.
  • FIG. 1 shows a conventional pump with a magnetic coupling, a rotatably mounted in a pump housing 1 rotor shaft 2, which has an impeller or a spindle 3 for conveying a fluid from a suction chamber 4 in a pressure chamber 5.
  • the rotor shaft 2 carries a rotor 6, which is arranged in a split pot 7, which is flowed through by the fluid.
  • the rotor 6 has an inner magnet 8, which by the magnetic field of an in FIG. 1 Outside magnet not shown in rotation is displaceable.
  • a leakage flow is required, which is driven by the pressure difference between the suction side and the pressure side of the pump.
  • the leakage current, which is mandatory for cooling the magnetic coupling is diverted from the conveyed medium by this of the pressure chamber 5 in the pump housing 1 through a gap 9 between a formed as part of the rotor shaft 2 throttle piston 10 and the pump housing 1 axially closing Cover 10 is guided.
  • the fluid After flowing through the gap 9, the fluid enters the containment shell 7, between the cover 10 and the rotor 6 of the magnetic coupling, through a narrow gap 11 between the inside of the can 7 and the rotor 6. From there, the fluid passes through a longitudinal bore 12 of the rotor shaft 2 again in the suction chamber 4 in the pump housing 1. In this flow guidance results in a non-negligible force in the axial direction, which acts on the rotating components and must be collected by appropriately solid bearing.
  • the invention is therefore based on the object to provide a pump with a magnetic coupling, in which the axial force acting on the rotor shaft is reduced.
  • a pump with a magnetic coupling of the type mentioned that the suction chamber and the containment shell are connected to each other via a line through which the fluid can flow.
  • the line leading to the containment shell in a position between the pump housing and the containment shell arranged lid opens.
  • the cover is thus located between the pump housing and the containment shell, the conduit connecting the suction chamber and the containment shell can be guided at least partially in the cover.
  • the cover arranged between the pressure chamber and the containment shell preferably has an opening which can be designed as a diaphragm. Due to the higher pressure in the pressure chamber compared to the containment shell, in which there is substantially the pressure of the pressure chamber, a fluid flow from the pressure chamber into the containment shell, which cools the magnetic coupling in the containment shell and in particular its rotor.
  • the opening in the lid opens into a gap between the outside of the rotor and the inside of the gap pot.
  • the rotor is almost completely surrounded by the fluid on its outside, whereby the heat generated during operation of the magnetic coupling is dissipated.
  • the size and the shape of the gap are chosen so that the fluid after flowing through the gap substantially to the pressure is relaxed in the suction chamber.
  • a sealing gap is formed between the cover and the rotor. This sealing gap prevents a substantial amount of the fluid from flowing from the opening directly into the area of the rotor shaft, Instead, the fluid is guided past the outside of the rotor, so that the desired cooling effect of the magnetic coupling is achieved.
  • the pump according to the invention can be designed in particular as a screw pump.
  • Pump 13 shown essentially consists of a pump housing 14 in which a rotor shaft 15 is rotatably mounted.
  • the rotor shaft 15 carries an impeller or a spindle 16 which is provided with an in Fig. 2 not shown second, opposite spindle meshes, wherein the spindles are formed with a spindle profile, so that during the rotation conveyor chambers are formed for a fluid, whereby the fluid is axially conveyed.
  • On the in Fig. 2 left side is the suction chamber 17 which is connected to an inlet, not shown, for the fluid, at the other end of the spindle 16 is the pressure chamber 18 which is connected to an outlet, not shown, for the fluid.
  • a lid 19 On the open on one side pump housing 14, a lid 19 is attached. On the cover 19, a split pot 20 is fixed, which receives a magnetic coupling.
  • the magnetic coupling comprises a rotor 21 which is fixedly connected to the rotor shaft 15. On its outer side, the rotor 21 has an inner magnet 22, which consists of a plurality of individual magnets. By a magnetic rotating field generated outside of the split pot 20, the rotor 21 can be rotated so that it via the rotor shaft 15, the intermeshing profile packages of Spindles 16 set in rotation, whereby the fluid is conveyed from the suction chamber 17 into the pressure chamber 18.
  • the lid 19 has an aperture 23 formed as a diaphragm, which passes through the lid 19 and is connected on the one hand to the pressure chamber 18 and on the other hand with a gap 24 which is formed between the inside of the can 20 and the outside of the rotor 21.
  • the opening 23 causes a portion of the fluid from the pressure space 18 to flow past the opening 23 and the gap 24 on the outside of the rotor 21, thereby cooling it.
  • the flowing fluid dissipates the heat generated by the external rotating field acting on the rotor 21.
  • the rotor 21 After the fluid has flowed around the rotor 21, it has been approximately relaxed to the pressure prevailing in the suction chamber 17 pressure.
  • the rotor 21 has a plurality of circumferentially distributed openings 25, so that the rotor 21 flows around virtually on all sides of the fluid and is cooled in this way.
  • a circumferentially circumferential sealing gap 26 is formed, which ensures that the fluid flows via the outside of the rotor 21 into the gap pot 20.
  • the rotor shaft 15 in the region of the lid 19 has a shoulder 27 with an enlarged diameter, so that the rotor shaft 15 acts as a throttle piston at this point.
  • a portion of the fluid also flows into the containment shell 20.
  • a portion of the line 29 extends in the illustrated embodiment in the lid 19, a further section extends outside the pump housing 14.
  • the line may be located completely outside the pump housing and directly into the interior the split pot open without being located within the lid.
  • arrangements are possible in which the line is arranged within the pump housing.
  • the diameter of the pipe 29 is selected so that the comparatively large amount of the flowing fluid, which flows on the one hand via the opening 23 and on the other hand via the opening 28 into the gap pot 20, can be removed.
  • the opening 23 is formed as a diaphragm whose opening diameter can be set differently depending on the pressure difference of the pump 13.
  • the pump shown has the advantage that no or only a small axial force is produced, which acts on the rotor shaft 15. An optionally occurring axial force is dependent only on the pressure losses in the openings of the magnetic coupling and the external or internal line 29, which leads into the suction chamber 17.
  • Another advantage is the fact that the amounts of serving as a cooling flow fluid is independent of the leakage through the gap at the shoulder 27 of the throttle piston acting as the rotor shaft 15, since the partial flows of the fluid for cooling and the leakage are separated. Since the rotor shaft 15 does not require a longitudinal bore, it can be made simpler compared to pierced rotor shafts.
