Definitions

  • the invention relates to a motor pump with a cooled Frequency converter and an electric motor that a wet or Has dry running.
  • the object of the invention is to provide a motor pump of the beginning to improve the type mentioned so that at simple Design and assembly optimal cooling of the Frequency converter is reached.
  • the Frequency converter has a plate as a heat sink, on the at least one generating heat Electronic component is attached, the plate in particular perpendicular to the axis of rotation of the engine and from a branched part of the pumped medium can be cooled.
  • Such a frequency converter can be on the front of the Motors simply attached as well as easily afterwards be replaced. This is a very good cooling the heat generated on the plate electronic components achieved.
  • the Frequency converter can be installed anywhere.
  • the plate has a Space limited by part of the medium is flowed through.
  • the delivery medium for 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 flow through a conduit that is in or on the outside of the motor and pump housing. This is it not required, as in the prior art known, a small part of the medium through the Interior of the motor shaft is returned to the pump, so that the pump shaft of simple construction and thus can be without an internal cavity.
  • At least one adjustable throttle is arranged in the cooling circuit (Secondary circuit) of the pumped medium. This allows the for the electronics required cooling to each required size can be set.
  • the pump Centrifugal or piston pump.
  • the pump can also have several pump stages, each with an impeller.
  • the medium flows from an inlet 7 ( Figure 2) into one Pump suction chamber 8 and from there via the impellers 3 in a pump pressure chamber 9 and from there via a Outer jacket 10 to outlet 4, with inlet 7 and outlet 4th are arranged coaxially and transversely to the pump axis.
  • the motor 5 has a coaxial can 11 in which the rotor 12 runs and that of the stator 13 Windings 14 is surrounded.
  • the motor shaft 15 is in Bearings 16, 17 held and on the shaft 18 of the pump attached.
  • the outer diameter D1 of the housing 21 is larger than that Outside diameter D2 of the motor and the outside diameter D3 of the pump.
  • the frequency converter 20 is a plate near the motor 5 22 arranged perpendicular to the motor and pump axis 23, so that the axis 23 is perpendicular to the plate 22.
  • the plate 22 is a heat sink for this Components.
  • the plate 22 has at least one channel 24 which is flowed through by a part of the medium to the Cool plate 22.
  • This channel 24 is located inside and / or to the side of the plate 22.
  • the channel 24 part of a secondary cooling circuit, wherein the channel is connected to a line 25 which coaxial from the plate 24 to the center, the pump opposite end of the can 11 is guided.
  • the end of the channel 24 is connected to 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 liquid of the secondary cooling circuit is from the pressure chamber 9 through an opening 27 in the Partition 28 branches off between the pump and motor, wherein through the opening 27, the medium into the interior of the Can 11 is guided to cool the engine.
  • the Pumped liquid flows through the containment can until to its end and from there through line 25 into the Channel 24 and then back through line 26 to Suction chamber 8.
  • the channel 24 is over the plate 22 not by the shortest route, but by the Center of the plate 22 to the outer edge and there over a large edge area to the outlet 29 at which the line 26th connected.
  • the channel 24 can also deviate from Figure 3 longer on the plate 22 in particular in Windings.
  • the pump only one pump stage own or be a piston pump. Especially It is advantageous that the pump in both horizontal can also be operated in a vertical position. Further the connection point 30 on the frequency converter 20 cannot be arranged only laterally, but also on the front.
  • the Electric motor no can or can have and thus be a dry runner.
  • the space between plate 22 and the end of the can 11 from the liquid filled so that the liquid there the Plate 22 cools and channel 24 does not necessarily is required.
  • secondary cooling circuit through the plate 22 and the Line 26 flows, an adjustable throttle arranged, so that the cooling circuit and thus the cooling of the plate 22nd is precisely controllable.
