Definitions

  • the invention relates to a pipe bushing through an opening of a guide vane carrier housing and an opening in an outer wall of an axial compressor housing a gas turbine.
  • the pipe duct is made by two or several walls led, due to relative movements horizontally and vertically against each other be moved.
  • the sealing of the pipeline takes place through soft material sealing rings at the outlet opening of the guide vane carrier housing.
  • a disadvantage of this conception is that if elasticity is lost due to the increased temperature of the sealing rings deflect and leakage occurs.
  • the object of the invention is a to create temperature resistant sealing that on the one hand is low-wear and on the other hand one unrestricted freedom of movement of the pipe duct guaranteed in the radial and axial directions.
  • the task is solved according to the characteristic features of the main claim.
  • the dependent claims relate to advantageous embodiments of the pipe duct.
  • the device according to the invention compresses Air from the guide vane carrier housing of an axial compressor a gas turbine via a pipeline taken. Since the guide vane carrier is within the Axial compressor housing, the pipeline through the annulus of the axial compressor, which by the Walls of the vane carrier housing and Compressor housing is formed, are performed.
  • the upper part of the Pipe with flange on the bushing or Extraction nozzle of the compressor housing wall firmly clamped and sealed by two seals.
  • the tube At the leadthrough or outlet opening of the guide vane carrier is the tube through a piston ring sealed.
  • the piston ring allows the relative movement of pipe and compressor housing opposite the guide vane carrier in the vertical direction.
  • the piston ring is passed through on the guide vane carrier wall led two mounting rings.
  • the mounting rings enable relative movement through their free spaces of pipe and compressor housing opposite the guide vane carrier in the horizontal direction.
  • the device according to the invention can be used in all Use cases where one pipe has multiple Walls that are exposed to relative movements, sealed penetrates.
  • the device is also characterized by the Metallic design temperature resistant, there are no wearing parts required. As part of the given freedom is an unrestricted Freedom of movement in radial and axial directions possible. Assembly of the device is very simple. There is a risk of excitation from flow forces locked out.
  • the invention is based on a schematic Embodiment explained in more detail.
  • Fig. 1 shows a longitudinal section through a Axial compressor of a gas turbine with on the shaft (19) arranged blades (21) and in the guide vane carrier (23) attached guide vanes (22) and one arranged below the diffuser (20) on the shaft (19) Impeller (18).
  • Air is transferred from the guide vane carrier (1) via a Pipeline (2) removed. Because the guide vane carrier (1) inside the compressor housing (3) the pipeline (2) must pass through the annulus (4) through the walls of the housings (1) and (3) is formed.
  • the upper tube part (2) has a flange (14) on the passage (6) of the outer housing wall (3) through the extraction nozzle (15) and by means of fastening elements (16) firmly clamped and by two Seals (7) sealed.
  • the piston ring (8) is on the guide vane carrier wall (1) through two mounting rings (9) and (10).
  • the mounting rings (9, 10) allow by their Free spaces or inner and outer dimensions (11, 12, 13) the relative movement of tube (2) and housing (3) opposite the guide vane carrier (1) in horizontal Direction.
  • the device according to the invention can also be Use cases where one pipe (2) has several Walls that are exposed to relative movements, sealed penetrates.
