Definitions

  • the invention relates to a motor pump with a cooled frequency converter and an electric motor having a wet or dry runner.
  • the object of the invention is to improve a motor pump of the type mentioned so that with a simple design and installation optimum cooling of the frequency converter is achieved.
  • the frequency converter has a plate as a heat sink on which at least one heat generating electronic component is attached, the plate is in particular perpendicular to the engine rotational axis and can be cooled by a branched part of the pumped medium and in the plate a channel , Which is traversed by the medium to cool the plate.
  • Such a frequency converter can be easily attached to the front of the engine as well as easily replaced later. In this case, a very good cooling of arranged on the plate heat generating electronic components is achieved.
  • the channel through which a part of the pumped medium not only leads to a good cooling of the plate, but also allows only relatively small amounts of liquid to circulate, so that it is not necessary to fill larger spaces within the motor pump with liquid.
  • the plate defines a space which is traversed by a part of the pumped medium. This also allows optimal cooling with simple design and installation.
  • the fluid to the plate flows through the interior of a canned or split pot of the engine. Further, the fluid should flow from the plate back to the pump suction side through a conduit located in or on the outside of the engine and pump housing. As a result, it is not necessary that, as known from the prior art, a small part of the pumped medium is returned to the pump through the interior of the motor shaft, so that the pump shaft can be of simple construction and thus without an internal cavity.
  • At least one controllable throttle is arranged in the cooling circuit (secondary circuit) of the pumped medium.
  • the cooling required for the electronics can be set to the required size.
  • the pump is a rotary or piston pump.
  • the pump may have multiple pump stages, each with an impeller.
  • a multi-stage centrifugal pump 1 with a pump housing 2, a plurality of impellers 3 and an outlet 4 is driven by an electric motor 5, which is fixed with its housing 6 coaxially to the pump 1.
  • the fluid flows from an inlet 7 ( Figure 2) into a Pumpensaughunt 8 and from there via the impellers 3 in a pump pressure chamber 9 and from there via an outer shell 10 to the outlet 4, wherein inlet 7 and outlet 4 are arranged coaxially and transversely to the pump axis ,
  • the motor 5 has a coaxial containment shell 11, in which the rotor 12 runs and which is surrounded by the stator 13 with windings 14.
  • the motor shaft 15 is held in bearings 16, 17 and fixed to the shaft 18 of the pump.
  • a frequency converter 20 with its cylindrical housing 21 is fixed to the rotor 5 on the front side and coaxially.
  • the outer diameter D1 of the housing 21 is larger than the outer diameter D2 of the motor and the outer diameter D3 of the pump.
  • a plate 22 is arranged perpendicular to the motor and pump axis 23 near the motor 5, so that the axis 23 is perpendicular to the plate 22.
  • On the plate heat generating electronic components are mounted so that they are in contact with the plate and thus the plate 22 is a heat sink for these components.
  • the plate 22 has at least one channel 24, which is traversed by a portion of the pumped medium to cool the plate 22.
  • This channel 24 is located within the plate 22.
  • the channel 24 is part of a secondary cooling circuit, wherein the channel is connected to a conduit 25 which is coaxially guided by the plate 24 to the central, the pump facing away from the end of the can 11.
  • the end of the channel 24 is connected to a return line 26, which is returned outside the motor pumps along the motor housing 6 and the pump housing 2 to the suction chamber 8.
  • the delivery liquid of the secondary cooling circuit is branched off from the pressure chamber 9 through an opening 27 in the partition wall 28 between the pump and the motor, through the opening 27, the fluid is led into the interior of the split pot 11 to cool the engine.
  • the delivery liquid flows through the containment shell to its end and from there through the conduit 25 into the channel 24 and then back through the conduit 26 to the suction chamber 8.
  • the channel 24 is guided over the plate 22 not by a shortest path, but from the center of the plate 22 to the outer edge and there over a large margin to the outlet 29 to which the conduit 26 is connected. Deviating from FIG. 3, the channel 24 can also be guided longer on the plate 22, in particular in turns.
  • the pump may have only one pump stage or be a piston pump. It is particularly advantageous that the pump can be operated both in a horizontal and in a vertical position.
  • the connection point 30 may be arranged on the frequency converter 20 not only laterally but also on the front side. Also, in contrast to the embodiment of the electric motor have no gap pot or no can and thus be a dry runner.
  • a controllable throttle is arranged in the secondary cooling circuit, which flows through the plate 22 and the line 26, so that the cooling circuit and thus the cooling of the plate 22 is precisely controlled.
