Definitions

  • the invention relates to a housing for a steam or gas turbine, which consists of a shell and two flanges.
  • Compressor housings for gas turbines which consist of a shell and two flanges. These housings have a pseudo flange in the upper and lower area of the shell.
  • these have the disadvantage that, when the gas turbine is in operation, greater radial expansions occur due to the higher mean temperature in the area of the pseudo flange, and thus the housing deviates from its round shape.
  • Housing for steam turbines are also known which consist of a shell and two flanges and which have vertical slots in the horizontal flanges.
  • expensive constructions and assembly devices should be avoided.
  • the object is achieved in that the shell has different wall thicknesses in an upper area facing away from the flanges, in two middle areas and in two lower areas facing towards the flanges, the wall thickness of the upper area facing away from the flanges compared to the wall thickness of the lower areas facing the flanges is reinforced and the wall thickness of the middle areas is variable, so that the upper area facing away from the flanges and the lower areas facing the flanges merge continuously into one another.
  • An advantage of this invention is that the variation in the wall thickness of the shell of the housing significantly reduces deformation into an ellipsoidal shape both in the radial direction and in the axial direction.
  • the housing thus has a small radial clearance between the housing and the ends of the turbine blades and thus has a significantly improved efficiency compared to the prior art. Overall, the invention achieves an improved efficiency of 0.2% to 0.3% of a steam turbine.
  • the single figure shows a section through an embodiment of a housing according to the invention.
  • the single figure shows a section through an embodiment of a Housing 1 according to the invention, which is used for steam or gas turbines becomes.
  • the entire case consists of two equal halves, only one of which is shown.
  • the housing 1 consists of a shell 2 and two flanges 3, which for attachment to the flanges of the second half of the Housing 1 is used.
  • the wall thickness of the shell 2 varies in different areas.
  • An upper area 5 facing away from the flanges is opposite the lower one Flanges facing areas 7 reinforced.
  • In the illustrated embodiment corresponds to the wall thickness of the upper region 5 facing away from the flanges 1.5 times the wall thickness of the lower areas facing the flanges 7.
  • the reinforcement of the area 5 facing away from the flanges no more than twice the Wall thickness of the lower areas 7 facing the flanges should have.
  • the upper area 5 facing away from the flanges and the lower area facing the flanges facing regions 7 are marked on each side by a central region 6 connected.
  • the wall thickness of these middle areas 6 varies, so that on each Since the two adjacent areas 5,7 merge continuously.
  • the upper area facing away from the flanges 5 arranged at 45 ° around the central axis 4 of the housing 1. After that the middle area 6 adjoins on both sides with 15 °.
