Definitions

  • the invention relates to a submersible motor pump with an electric drive motor, under which the housing of a centrifugal pump is fastened, the housing of the motor being coaxially surrounded on the outside by a cooling jacket through which the pumped medium flows.
  • the object of the invention is to improve a submersible pump of the type mentioned in such a way that optimum cooling performance is always provided.
  • the outflow of the cooling jacket annulus is formed by a tube which lies approximately axially parallel to the pump axis in the cooling jacket annulus and extends from the partition between the pump housing and the motor into the uppermost region of the annulus.
  • Such a pipe forming the drain inside the cooling jacket annulus leads to the coolant always being removed from the uppermost region of the cooling jacket or the annulus and thus reliably removing air, gases and dirt particles.
  • the annulus is always filled and optimally flowed through, so that a high and constant cooling capacity is achieved.
  • construction and assembly are particularly simple and the external dimensions are not enlarged.
  • the inlet of the drain pipe is turned away from the direction of flow of the cooling liquid. This reliably prevents the pipe inlet from becoming blocked.
  • cooling jacket tapers conically in the upper region and the conical, oblique region clamps the upper end of the tube. It is therefore not necessary to provide additional fastening parts such as fastening clamps in the upper area for the pipe. Rather, it is safe to do that alone Pinched.
  • the submersible motor pump has an electric motor 1, the shaft 2 of which is vertical and is extended downward in order to reach into the pump housing 3 of a centrifugal pump 4.
  • the motor 1 has a stator 5 and a rotor 6 attached to the shaft 2.
  • the shaft 2 is held by an upper and a lower bearing 7, 8, which are fastened in an upper bearing bracket 9 and a lower bearing bracket 10.
  • the pump impeller 11 is mounted on the lower end of the shaft 2.
  • the electrical connection cable 12 of the motor 1 is guided in the interior of the motor via a cable socket 13 on the top of the motor. Furthermore, a holder 14 is fastened to the upper side of the motor in order to be able to lift the submersible motor pump in particular by means of a crane.
  • the housing 15 of the motor 1 is made of stainless steel and is made by flow lines.
  • the stator 5 of the motor is pressed together with the rotor 6 and the other motor parts into the interior of the housing 15.
  • the bearing supports 9, 10 are made of aluminum and can also be fastened by being pressed in.
  • the motor housing is coaxially surrounded by a cooling jacket 16 so that the cooling jacket with the outside of the Motor housing 15 forms an annular space 17.
  • This annular space 17 is flowed through by a cooling liquid, in particular water, which is branched off from the pumped medium.
  • the cooling jacket 16 is made of stainless steel and is attached to the motor by pressing.
  • the pump housing is made of plastic, in particular polyurethane.
  • the pump impeller 11 is made of plastic, in particular polyurethane.
  • a pipe 40 forming the drain which is connected at its lower end to a transverse bore 41 in the pump housing 3, which is located in the transverse wall 43 which separates the motor from the pump housing.
  • the transverse bore 41 leads to the pump interior in which the impeller 11 is mounted.
  • the upper end of the tube 40 is angled about 90 degrees.
  • the angled end with its inlet opening 42 faces away from the circulating flow direction of the cooling liquid.
  • the tube 40 is close to the outer wall of the motor housing 15; in particular, it is due to this. So that the pipe 40 is close to the outer wall of the motor housing, it is bent twice in the lower region 45 (bent).
  • the cooling jacket 16 tapers conically in the upper region, the conical oblique region 44 holding the upper end of the tube in a clamping manner.
