Definitions

  • the invention relates to a motor pump with a cooled frequency converter and an electric motor that has a wet or dry runner.
  • the object of the invention is to a motor pump of the type mentioned improve that with simple construction and assembly optimal cooling of the frequency converter is reached.
  • the Frequency converter as a heat sink has a plate on which at least one Heat-generating electronic component is attached, the plate in particular is perpendicular to the motor axis of rotation and from a branched part of the Fluid can be cooled and a channel runs in and / or on the plate, the is flowed through by the medium to cool the plate.
  • Such a frequency converter can be easily attached to the front of the motor can also be easily replaced afterwards. This will be a very good one Cooling of the electronic heat generated on the plate Components reached.
  • the channel through which part of the pumped medium flows not only leads to good cooling of the plate, but also allows that only relatively small amounts of liquid have to circulate so it doesn't It is necessary to liquidate larger spaces within the motor pump to fill.
  • the plate it is also possible for the plate to delimit a space, which is traversed by part of the medium. This also enables optimal cooling with simple construction and assembly.
  • the medium to the plate through the Inside of a can or can of the engine flows. Furthermore, that should Pumped medium from the plate back to the pump suction side through a line flow, which is in or on the outside of the motor and pump housing. As a result, it is not necessary that, as is known from the prior art, a small part of the pumped medium through the interior of the motor shaft to the pump is returned so that the pump shaft of simple construction and so it can be without an internal cavity.
  • cooling circuit secondary circuit
  • Delivery medium is arranged at least one controllable throttle. hereby can the cooling required for the electronics to the required size can be set.
  • the pump be a centrifugal or Piston pump is.
  • the pump can also have several pump stages, each with one Have impeller.
  • the medium flows from an inlet 7 (FIG. 2) into a pump suction chamber 8 and from there via the impellers 3 into a pump pressure chamber 9 and from there via a Outer jacket 10 to outlet 4, inlet 7 and outlet 4 being coaxial and are arranged transversely to the pump axis.
  • the motor 5 has a coaxial can 11 in which the rotor 12 runs and the is surrounded by the stator 13 with windings 14.
  • the motor shaft 15 is in Bearings 16, 17 held and attached to the shaft 18 of the pump.
  • the rotor 5 On the side facing away from the pump 1, the rotor 5 has an end face and is coaxial Frequency converter 20 attached with its cylindrical housing 21.
  • 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 perpendicular to the motor 5 Motor and pump axis 23 arranged so that the axis 23 perpendicular to Plate 22 is.
  • Electronic components that generate heat are such on the plate attached that they are in contact with the plate and thus the plate 22 a Is heat sink for these components.
  • the plate 22 has at least one channel 24 which is part of the Flow medium is flowed to cool the plate 22.
  • This channel 24 is located inside and / or to the side of the plate 22.
  • the channel 24 is part of a secondary cooling circuit, the channel being connected to a line 25 is connected, the coaxial from the plate 24 to the center, the pump opposite end of the containment shell 11 is guided.
  • the end of channel 24 is on a return line 26 connected outside the motor pumps along the motor housing 6 and the pump housing 2 to the suction chamber 8 is returned.
  • the delivery liquid of the secondary cooling circuit is from the pressure chamber 9 through an opening 27 in the partition 28 between the pump and motor branched, through the opening 27, the medium into the interior of the Can 11 is guided to cool the engine.
  • the liquid is flowing through the can to its end and from there through the pipe 25 into the channel 24 and then back through the line 26 to the suction chamber 8.
  • the channel 24 over the plate 22 is not the shortest Led away, but from the center of the plate 22 to the outer edge and over there a large edge area to the outlet 29 to which the line 26 is connected is. Deviating from FIG. 3, the channel 24 can also be longer on the plate 22 be led in particular in turns.
  • the pump have only one pump stage or one Piston pump. It is particularly advantageous that the pump both in can be operated horizontally as well as in a vertical position.
  • the Junction 30 on the frequency converter 20 not only on the side, but also be arranged at the end.
  • the Electric motor have no can or can and therefore one Be a dry runner.
  • the space between plate 22 and the end of the containment shell 11 filled by the conveying liquid, so that the liquid located there cools the plate 22 and the channel 24 does not necessarily is required.
  • an adjustable throttle arranged so that the cooling circuit and thus the cooling of the plate 22 exactly is controllable.
