Abstract
The invention relates to a steam turbine, whose shell is provided with a ring-shaped support structure (3), wherein the shell is also provided with rotors and comprises a component (5), such as a combustion chamber, a cooling system, and the like, the ring-shaped support structure (3) can be fixed on a shell (2) in rotating and is locked in at least one position, components which need periodical examination and updating are all fixed on the support structure.
Description
Technical background of the present invention
The field of the invention
The present invention relates to a kind of steam turbine as described in the preamble as claimed in claim 1.
Technical background
In the maintenance process of steam turbine, want running check or dismounting and change assembly.For this reason, often top, the upper half-shell of steamer casing need be pulled down so that near these assemblies.This part dismounting bothers time-consuming very much, thereby also very expensive; Particularly, remove usually at a glance, this assembly can also continue to use.And, to compare with the actual inspection time, this part dismounting needs a large amount of built-up times.
General introduction of the present invention
Therefore, an object of the present invention is to attempt to avoid all these shortcomings, a kind of steam turbine of novelty is provided, it needn't be for checking or changing the assembly part and dismantle previous the sort of degree.
This purpose is that the feature by the characteristic of claim 1 realizes.The feature of dependent claims specifically defines the advantageous embodiments of steam turbine.
Brief description of the drawings
Present invention is described below with reference to accompanying drawing, can to the present invention with and the advantage of each side more understanding is arranged.
Fig. 1 shows the part of steamer casing briefly, and broken section has been carried out in some place;
Fig. 2 schematically illustrates a partial sectional view that passes steam turbine perpendicular to the axis of steam turbine.
Only illustrate among the figure and be used to understand the basic element of character of the present invention; Particularly do not change in the steam turbine, itself or its any parts all are known parts.
The description of preferred embodiment
With reference now to accompanying drawing,, the identical label among each figure is represented same or corresponding components, and steam turbine 1 has a housing 2, and a rotor 4 is housed in the shell, and this housing also has peripheral assembly, and for example firing chamber, cooling system etc. have supporting structure 3 in the housing 2.This annular supporting structure 3 rotatably is contained in the housing, and may be locked at least one position.All need the assembly 5 of periodic test and replacing all to be contained on the supporting structure.In order in the checking process of steam turbine 1, annular supporting structure 3 to be rotated to each assembling if desired the time or to check the position, it is connected with a device, this device is locked in operating position with annular supporting structure 3 on the one hand, and on the other hand, it is moved to necessary assembling or checks the position.This device that is used to rotate annular supporting structure 3 is arranged between housing 2 and the annular supporting structure 3 or between the latter and rotor 4.The housing 2 of steam turbine 1 has at least one closable assembly hole 6, and its size and dimension makes the assembly 5 of the steam turbine 1 that must check and change approaching easily, perhaps can be easy to dismantle and pull down.Particularly, if some component holes 6 are arranged, they are distributed in two planes perpendicular to axis basically, these two planes are corresponding to the assembly 5 in the housing 2.The assembly 5 that has so just guaranteed steam turbine is come-at-able, and the result has reduced dead time significantly.In addition, She Ji steam turbine by this way has been no longer necessary for the approaching assembly that needs to change or check and housing parts has been taken apart, thereby constitutes sizable saving in checking process.
Obviously, can obtain a lot of improvement of the present invention and variation according to top instruction.Therefore, should be appreciated that, in the scope of claims, can implement the present invention by other method outside the method that specifically is described at this.
Claims (5)
1. steam turbine, it has a housing, one rotor is housed in the housing, this housing also comprises peripheral assembly, for example firing chamber, cooling system etc., it is characterized in that: have an annular supporting structure (3) in the housing (2) of steam turbine (1), this annular supporting structure (3) rotatably is contained in the housing, and may be locked at least one position, all need the assembly (5) of periodic test and replacing all to be contained on this annular supporting structure.
2. assembly as claimed in claim 1 is characterized in that: annular supporting structure (3) is connected in a device, and this device rotates to different working positions with annular supporting structure (3) when needed.
3. steam turbine as claimed in claim 2 is characterized in that: the device that is used for rotary annular supporting structure (3) is arranged between housing (2) and the annular brace device (3) or between the latter and the rotor (4).
4. as each described steam turbine in the claim 1 to 3, it is characterized in that: on the housing (2) of steam turbine, be provided with at least one closed component holes (6), so that change or check the turbine unit (5) that is arranged in the housing (2).
5. steam turbine as claimed in claim 4 is characterized in that: if a plurality of component holes (6) are set, they are arranged in two planes corresponding to the assembly (5) in the housing (2) basically.
