Definitions

  • the pipeline described can be a simple pipeline from a single pipe or an insulating one Pipe in a support arm made of an outer tube and laid in the outer tube and insulated against this inner tube consist.
  • An insulating pipeline is used for the supply of a hot fluid to a shaft seal or for discharge of a hot fluid from a shaft seal.
  • Such one hot fluid is e.g. Vapor coming into the camp for sealing purposes is supplied, or vapor, i.e. steam, which leaks out of the bearing, possibly through air and / or oil vapor is contaminated and must be removed.
  • the task for an initially mentioned Component solved in that at least one in the first material fluid guidance extending in regions in the circumferential direction is provided, which is open to the inner wall and is fluidly connected to the fluid line and wherein the fluid line fluidically with the inner wall connects the outside area.
  • the fluid line is preferred poured into the first material.
  • the component is preferably part of a half-shell Turbine housing, in particular an outer housing Steam turbine.
  • a turbine shaft in the area of a shaft seal, preferably comprising a fluid line system the fluid guide and the fluid line of the removal of Vapor vapor and another supply fluid line system of sealing steam.
  • a fluid line system for delivery Barrier steam has a pressure of approximately 1.05 bar (a slight overpressure) and in the fluid line system for suction a small negative pressure of about 1.0 bar set. This is a tightness of the shaft seal as well as the extraction of vapor from the steam.
  • the fluid line is preferably a simple pipeline to transport a fluid.
  • This fluid can have a temperature have, which with the temperature one through the fluid machine flowing fluid roughly matches, so that due to temperature differences of the fluids at best low thermal stresses can be expected.
  • A is preferably for a component mentioned at the beginning Fluid line system with a fluid guide and a fluid line, the latter also referred to as a line segment is that the inner wall fluidically with the Connects outer wall, the fluid guide at least in some areas is directed in the circumferential direction and for production a fluidic connection with the inner wall has at least one opening, in particular a slot.
  • a circumferentially extending fluid guide which a fluidic connection with the inner wall manufactures, forms part of a simple way Annular chamber, which requires no further mechanical processing requirement.
  • the fluid guide guided in the circumferential direction preferably forms a half ring, by joining together two components surrounding a shaft a complete die Wave surrounding ring is formed.
  • the fluid line system consisting of the Fluid guide 4A and the fluid lines 5 for supply or Removal of sealing steam and the fluid line system comprehensively the fluid guide 4B and the fluid line 6 for discharge of steam vapor shown in spatial representation, as in a component 1 of a half of a slit Turbine housing 10 are cast.
  • the fluid lines 5 and 6 are directed radially outwards and protrude from the component 1 so far that a welded connection with a Supply or discharge system, not shown, simple can be produced.
  • the semi-ring-shaped grooves Fluid guides 4A, 4B are slot-shaped to the turbine shaft 15 open.
