Definitions

  • the invention relates to a magnetic clutch pump for conveying hotter Media, with a lantern surrounding the magnetic coupling and a detachable on the Lantern attached bearing bracket, in which two roller bearings are arranged, one of which Shaft for connecting a drive motor to the primary part of the magnetic coupling wear, with a heat barrier between the lantern and the bearing bracket is arranged.
  • Usual magnetic coupling pumps can reach a temperature of around 250 ° C operated without changes.
  • chemical standard pumps are used. Among other dimensions is the overall length of such pumps is also subject to the standard. But especially in the Chemical industry also has a need for such pumps that use media Are able to promote temperatures between 250 ° C and 300 ° C Demand for a magnetic clutch pump that can withstand these temperatures and adheres to the dimensions of the standard pump.
  • EP 0 814 268 A1 teaches one Heat barrier, which as a separate component within a modular kit Manufacture of a pump, in particular a permanent magnet coupling pump, Is used.
  • the thermal barrier essentially consists of two plates are separated from each other by several radially extending ribs; it will be between the lantern and the bearing bracket. To use this thermal barrier too must have an extended coupling shaft compared to the normal version be used.
  • a major disadvantage of the known heat barrier is the fact that with the use of a magnetic coupling pump above the standard length arises.
  • an embodiment is proposed that is characterized by an exchange for a bearing bracket without Heat barrier serving bearing bracket with heat barrier and one also shaft to be replaced, the distance between the roller bearings compared to the Version without heat barrier is shortened and the bearing bracket with Thermal barrier, like the shaft arranged in it, the same axial extent have like the bearing bracket and the shaft version without heat barrier.
  • the Bearing bracket by a recess on the side of the magnetic coupling provided rotating part and a wall part closing the recess is formed, the two parts being connected by welding.
  • the invention is explained in more detail using an exemplary embodiment.
  • the drawing shows a magnetic coupling pump according to the invention in a sectional view.
  • the magnetic clutch pump comprises a pump housing 1, in which one on a Shaft 2 attached impeller 3 is arranged. On its print page it will Pump housing 1 closed by a pressure cover 4. Within the Pressure cover 4, a bearing housing 5 is arranged in the slide bearing 6 for the shaft 2 are provided.
  • a drive serves to drive the shaft 2 and thus the impeller 3 Electric motor - which engages a shaft 7.
  • the shaft 7 is by means of two ball bearings 8 stored in a bearing bracket 9.
  • the shaft 7 carries the primary part 10 Magnetic coupling 11.
  • the secondary part 12 which is firmly connected to the shaft 2 Magnetic coupling 11 is from the primary part 10 through a liquid-tight containment shell 13 separated.
  • the magnetic coupling 11 is enclosed by a lantern 14.
  • the wall 15 of the bearing bracket 9 facing the magnetic coupling 11 is with the lantern 14 releasably connected, it is designed as a heat barrier 16.
  • the bearing bracket 9 is designed as a rotating part, which is closed by a wall part 17 welded to it.
  • the wall part 17 thus closes a cavity 18 formed in the rotating part, which is connected to a thermal insulation material 19 is filled.
  • the wall 15 of the bearing bracket 9 and the heat barrier 16 enclosed therein have a bulge that extends into the lantern 14.
  • Wall part 17 is plate-shaped, so that the ball bearing 8 accommodating space of the bearing bracket 9 an expansion in the direction of the interior of the lantern 14th experiences. This will make the space necessary to accommodate the storage extended.
  • the insulating material 19 arranged in the cavity 18 follows the given bulge.
  • the bulge of the heat barrier 16 entails that the ball bearing 8 receiving space and thus the bearing bracket 9 in the direction of the magnetic coupling 11 be moved. This measure allows the entire axial extension of the Reduce magnetic clutch pump with thermal barrier. Achievement of the goal, a Chemical standard pump with heat barrier to create such a length without heat barrier, this will make it much easier.
  • Another possible measure for reducing the axial extent exists in that the distance between the ball bearings 8 compared to the execution without To reduce heat barrier, which then a change in the shaft 7 in the rest Storage area necessary.
  • the measure shown makes it possible, especially in Combination with the bulge of the heat barrier 16 described above, a Standard chemical pump suitable for temperatures up to 250 ° C for use up to 300 ° C convert.
