Definitions

  • the FIG. 1 shows a part of a steam turbine 1.
  • the steam turbine 1 has a housing 2 and a rotatably mounted within the housing 2 rotor 3.
  • the steam turbine 1 has a plurality of stages 4.
  • the stages 4 form a flow channel 5 through which a flow medium flows in a flow direction 6 during operation.
  • the rotor 3 has a discharge 7 after a first discharge stage 41.
  • the derivative 7 can be designed as a bore. It can be distributed over the circumference formed as a derivative 7 more holes.
  • the interior 8 of the rotor 3 is designed as a bore 9 and extends from one end 10 of the rotor 3 to a point which is referred to as the inflection point 11.
  • the rotor 3 is in this case designed such that the flow medium flows upstream 12 within the rotor 3 up to the inflection point 11 and after the inflection point 11 flows downstream 13. Via a discharge line 14, the flow medium finally flows into the flow channel 5. The medium can then perform work.
  • FIG. 2 is a detailed representation of a section of the steam turbine 1 from FIG. 1 shown.
  • the bore 9 has an inner tube 15 which is arranged centered in the bore 9.
  • the inner tube 15 is in this case formed such that the length is shorter than the length of the bore 9 and the inflection point 11, the inner tube 15 is formed such that the flow medium from the bore into the inner tube is deflected. The deflected flow medium then flows downstream 13.
  • the inner tube is in this case formed with a pipe guide 16 at the inflection point 11.
  • the pipe guide 16 in this case has not shown through holes for the passage of the flow medium.
  • a plug 17 is arranged at a downstream point of the inner tube 15.
  • the plug 17 is in this case designed such that the flow medium from the discharge line 7 is directed upstream 12 and prevents a deflection downstream 13.
  • the plug 17 serves to center the inner tube 15th
  • FIG. 4 is a detailed view of Section A can be seen.
  • a pipe guide plug 22 is arranged at the inflection point 11 of the bore.
  • the pipe guide plug 22 is designed for centering the inner tube 15.
  • the pipe guide plug 22 is formed such that the flow medium does not flow out of the first part rotor 22 at the inflection point 11.
  • the inner tube 15 has in the vicinity of the pipe guide plug 22 through holes 23 through which the flow medium can flow into the inner tube 15. These holes represent the inflection point of the flow in this variant.
