Definitions
- Inner casing for a turbomachine Inner casing for a turbomachine.
- housings are generally divided into horizontally (or vertically) divided housings and housings consisting of rings.
- a pot housing with suspended segments is another known option.
- the gap control is generally carried out - if any at all - by blowing on the housing over the rotor blades.
- the invention is intended the combination of the advantages of ring and horizontally split housings can also be achieved.
- the assembly and disassembly is to be simplified.
- the drawing shows an example of a housing structure with guide vanes in its vicinity.
- the casing string consists of the annular end housings 1 and 2, the horizontally divided connecting housings 3, 4, 5 and 6, the annular blow-off housings 7 and 8 and the likewise annular lining carriers 9, 10, 11, 12 and 13.
- the guide vanes are 14, 15 , 16, 17 and 18 marked, the indicated blades with 19, 20, 21, 22, 23 and 24. Furthermore, covers 25, 26, 27 or thermal insulation layers 28, 29, 30 and 31 applied.
- Housings have centering seats, which also serve to hold the guide blade root; the tarnished housings are to be treated separately, the spray layers are perfectly accessible on both sides; no deep, inaccessible punctures for the guide blade root admission.
- the guide vanes 15 are brought radially inward in the area of the dimensions 32 and pushed axially onto the lining carrier 9.
- the lining carrier 10 is pushed into the right hooks of the guide blades 15, the radial position of these guide blades being able to be checked from the outside.
- the axially divided housing 3 is placed over lining supports 9 and 10, is screwed radially to the joint 34 and then axially screwed to the lining supports.
- Disassembly of the complete rotor takes place in the reverse order of assembly, the guide vanes 15 being able to be held from the outside when the lining strip 10 is disassembled.
