Definitions

  • the invention relates to a turbomachine, in particular a compressor, in a pot design according to the preamble of claim 1.
  • a turbomachine is generally known in practice.
  • the object of the invention is to provide a turbomachine, in particular a compressor Specify pot construction, in which a conversion construction without the described Problems is possible.
  • the essence of the invention is the mounting of the bearing block on from the housing protruding face end of the stator of the bundle. It is essential to the invention that the bearing block with the bundle and not with the housing connected is. In a conventional construction, the flange of the Bearing block screwed directly to the housing.
  • the arrangement according to the invention enables exact positioning of rotor parts to stator parts outside the Housing. Since the losses of a turbomachine are largely determined by the The size of the gap between the rotor and stator part is influenced, is the optimal Alignment between the rotor and stator part of the bundle is crucial Importance.
  • the exact location can be assigned be fixed between the rotor and stator part by cylindrical and / or tapered pins, so that after dismantling the bearing blocks, the aligned bundle in the housing can be inserted. Regardless of the position of the bundle
  • the axis of the housing remains the set one that determines the power loss Position assignment between rotor and stator part obtained. This makes possible Influences on the operating behavior and operational safety of the machine any deviations in the existing housing in the bundle fit area to the housing and bundles to the lid avoided.
  • the existing housing and the existing cover has no influence on the position of the rotor in relation to the stator parts. For this reason it is possible to check the installation position without the housing Make rotor to stator part. This eliminates risks when mounting on the Construction site minimized in an existing housing.
  • the adapter is primarily used to: a compensation for that in most cases a smaller diameter having the end of the stator protruding from the housing and the one to create larger diameter flange of the bearing block.
  • the adapter can also be used to hold a seal (e.g. locking labyrinth) between the bearing block and the shaft seal can be used with gas-lubricated Seals and labyrinth seals, as well as with oil-lubricated seals separate oil system, d. H. Bearing oil and sealing oil are separate, is required.
  • the sealing gas can be connected directly to the adapter.
  • the adapter can also for performing connection bores to seals or chambers in the End of the stator can be used.
  • the turbocompressor shown in the single figure has a housing 1 in Pot design.
  • the area on the left is here the housing 1 with a fixed contact shoulder 2.
  • This housing 1 consisting of rotor 3 and stator parts 4, 5 and a shaft 6 bundles axially inserted.
  • the stator part 5 of the bundle on the left comes to the System shoulder 2 to the system.
  • the end on the right side is a cover 7, which is connected to the housing 1 via screws 8.
  • the respective front End 9, 10 of the stator 4, 5 protrudes beyond the end closure of the cover 7 or the housing 1 also.
  • the other side of the adapter 11, 12 is with the respective bearing block 13, 14 connected. That in this embodiment here on the left arranged bearing is as a radial bearing 15 and the bearing arranged on the right as Radial axial bearing 16 is formed.
  • the bundle is guided in the radial direction on the one hand via the bore 17 in the contact shoulder 2 of the housing 1 and others in the bore 18 of the cover 7.
  • the Bundle under operating conditions through the contact shoulder 2 in the housing 1 and by the radial thrust bearing 16 arranged here on the right.
  • the seal between Suction pressure 19 and final pressure 20 in the bundle to the housing 1 takes place between a the stator part 5 and the housing 1 arranged seal 21.
  • the exemplary embodiment is a locking labyrinth 23 as a seal in both adapters 11, 12 arranged between the bearing block 13, 14 and shaft seal. The sealing gas is thereby fed to the respective locking labyrinth 23 via an insert 22.
