Definitions

  • the present invention relates to a support device for a condensation steam turbine, in which a condenser is flexibly connected to a turbine housing and the condenser is firmly anchored to a substructure.
  • the structural unit which is formed from the condenser and the low-pressure outer housing, is placed on the base plate of the foundation and is guided by means of fixations relative to the machine foundation and the base plate (DE - A 1 551 192 or CH-A 461 536).
  • the aforementioned object is achieved in that the turbine parts exposed to the vacuum train are fastened to a foundation support which is connected on the one hand to the substructure via a support and on the other hand is arranged within a spring-mounted foundation.
  • the advantage of the support device according to the invention can be seen in particular in the fact that no displacement on the spring-mounted turbine parts occurs as a result of the vacuum pull.
  • a further advantage is based on the fact that the condenser, which is fastened to the floor and flexibly connected to the turbine, can be formed without special installation measures when using a spring-mounted foundation.
  • the capacitor is designed as a support.
  • This configuration of the capacitor means that no further supporting structures are required.
  • the foundation carrier is supported on a supporting structure for the spring-mounted foundation.
  • the turbine housing 1 is a turbine housing which is connected to a condenser 2 via flexible connections 3.
  • the capacitor 2 is firmly connected to a substructure 4.
  • the turbine housing 1 exposed to the vacuum train is rigidly connected to the substructure 4 with claws 5 on foundation supports 6, which each rest on a support 7, while the other turbine parts not exposed to the vacuum train, for example the bearing housing (not shown) on a spring 8 stored foundation 9 are arranged.
  • the foundation 9 is connected to the substructure 4 via a support structure 10 and is preferably designed like a frame, so that the foundation supports 6 can be arranged within this frame, as can be seen from FIG. 1 a. With such a form of construction, the ends of the foundation carrier 6 could be chamfered, so that they fit into receptacles of the foundation 9 which are formed in an analogous manner, but do not hinder its resilient mobility.
  • the capacitor 2 is designed as a support, so that the foundation supports 6 are supported on the latter with intermediate pieces 11 designed analogously to the contour of the capacitor.
  • the formation of the foundation 9, the springs 8 and the support structure 10 is identical to that of FIG. 1.
  • the turbine housing 1 rests with the claws 5 on the foundation support 6, which is supported on the same supporting structure 10 as the foundation 9. The spring properties of the foundation 9 are not affected.
