Definitions

  • the invention relates to a turbomachine, in particular compressors or turbocompressors for low-temperature applications, wherein the turbomachine has a housing.
  • Such turbomachines with housing are known.
  • housings of compressors or turbocompressors must be designed so that they can withstand a high internal pressure.
  • ⁇ operating temperatures ⁇ -120 0 C
  • materials in particular cold ⁇ tough steels with an austenitic crystal structure to manufacture lung of the housing to be used, wherein the cryogenic steels with an austenitic crystal structure disadvantageously have a very low strength
  • current housing of compressors or turbo compressors for low temperature applications with relatively large wall thicknesses are performed in order to withstand the relatively high internal pressure at the very low strength of the material.
  • the invention has the object of providing a housing, in particular ⁇ sondere a housing for the compressor, preferably for turbo compressors for low temperature applications, the effect to improve with simple means that the housing manufacturing even at very low operating temperatures with smaller wall thicknesses is adjustable.
  • the object is achieved in that the Ge ⁇ housing consists of a cold-tough material with martensitic structure.
  • the housing consists of a cold-carbon cast steel
  • the housing consists of a cold-tough cast steel ⁇ with a nickel content of 8.5 to 10%.
  • the object is also achieved in that for the preparation of a turbo compressor housing for low temperature applications ⁇ a cold-ductile material with a martensitic structure is used, in which case preferably the material ASTM A 352 LC 9 is suitable.
  • Cryogenic cast steels with high nickel content are in particular ⁇ sondere for low temperatures down to -196 0 C. Due to the advantageous alloy composition is the structure of nickel-alloyed steels, martensitic, being higher compared to steels with an austenitic crystal structure 0.2% - yield strength, low thermal expansion and a have higher heat ⁇ conductivity.
  • the higher yield strength advantageously allows lower wall thicknesses of the housing, whereby less housing material is required, so that the costs for producing the housing are considerably reduced.
  • the combination of properties of the cold-strength cast steels with a high nickel content, in particular of the material ASTM A 352 LC 9, achieves better temperature gradients and reduces thermal stresses, thus excluding the risk of plastic deformation.
