Definitions

  • the invention relates to a pot housing for centrifugal pumps according to the preamble of the main claim.
  • Such a pump construction is known from US-A-3 153 383, in which a stage housing package clamped together by tie rods abuts an attachment of the pot housing in the area of the suction side.
  • the pot housing In the end region on the suction side, the pot housing has a machined, internal extension, the inward-facing end face of which forms an axial contact surface for the first stage of the stage housing package.
  • the stage housing package is pressed against this approach by the pressure-side housing cover of the pot housing.
  • the approach serves to absorb those forces that prevail within the pot housing and that are determined by the geometry of the hydraulic internals and the sealing forces.
  • the contact surface for the stage housing thus forms the separation between the low pressure side of the inlet and the highly loaded area at the pump outlet or the pot housing enveloping the stage housing.
  • the prevailing surface pressure on this contact surface requires a certain radial width and thus also determines the inside diameter of the pot housing. Because of this, the pot housing is generally thicker on the inlet side, despite the lower
  • the invention has for its object to develop a little complex pot housing, which is easy to manufacture under high loads. This object is achieved in accordance with the characterizing part of the main claim.
  • Another embodiment of the invention provides that the insert or inserts are arranged within the pipe section.
  • the outer end face can end with the pipe section or come to rest within the same.
  • the housings manage with a minimum of machining.
  • the pipe section and inserts can be made from cast, rolled or forged pipe sections. After insertion and alignment, it is sufficient to weld the parts, to fix them in place by means of screw connections or in a form-fitting manner. Since the maximum surface pressure occurring within the pot housing is absorbed by the inserts, the material of the inserts forming the shoulder should have at least the strength of the step housing acting against it.
  • a further embodiment provides that the insert arranged within the pipe section is an overlay welded collar. This measure further simplifies production.
  • Fig. 1 shows schematically, using the example of the pot housing according to US Pat. No. 3,153,383, how much material is to be removed from a blank.
  • the cross-hatched areas correspond to the areas to be processed. Even if, for example, the blank was already forged, there are enough surfaces that are difficult to machine.
  • annular insert 2 is so force-absorbing and sealingly introduced that one end protrudes from the pipe section 1 and forms the low-pressure part of the pot pump. Compared to the pipe section 1 covering the high pressure area, it is designed to be correspondingly thinner.
  • the contact surface 3 serves to support the stage housing package 4 shown in broken lines, in particular as a system for the stage housing of the first stage.
  • Fig. 3 an embodiment is shown in which a shorter and thinner insert 2 is fully inserted into the pipe section 1 and here ends flush with the end.
  • the cohesion takes place here, as in FIG. 2, by means of a welded connection 5.
  • this has only a sealing function, since the forces acting on the surface 2 can be absorbed by the cover 8 shown in broken lines.
  • FIG. 4 shows an embodiment in which the insert 2 was created by means of surfacing. Its dimensions are from depending on the strength values of the materials used.
