DE19719770A1 - Turbine machine - Google Patents

Abstract

The turbine machine (1) has a casing (2) containing the rotor, combustion chambers, cooling system etc. There is an annular bearing structure (3) in the casing, which can rotate and can be locked in at least one position. All the components (5) which have to be checked or changed periodically are mounted on this bearing structure. The bearing structure may be connected to a device which can turn it into different working positions as required. The device is between the casing and the bearing structure, or between the bearing structure and the rotor.

Description

Technical field

The invention relates to a turbomachine according to the preamble of the patent claim 1.

State of the art

For turbomachinery, they must be regularly related to maintenance be checked or removed and replaced. It is for that required that in general the upper part, the upper half-shell of the Housing of the turbomachine is removed to give access to this construction groups. Such partial disassembly is very complex and time consuming, therefore expensive. In particular, in order to determine that the over tested modules are still functional. It also requires one such partial disassembly disproportionate time compared to the actual test time.

Presentation of the invention

The invention tries to avoid these disadvantages. It is her job based on specifying a turbomachine for which to check or not for the replacement of assemblies required are.  

The solution to this problem is with the characteristics of the indicator of Claim 1 circumscribed. Advantageous embodiments of a door bomaschine are indicated by the features of the dependent claims.

Brief description of the drawing

Further features and advantages result from the description of a exemplary embodiment with reference to the drawing. In this shows:

Fig. 1 shows diagrammatically, partially cut away part of the casing of a turbomachine,

Fig. 2 shows schematically a partial section (AA) through the turbo machine perpendicular to its axis.

They are only the elements essential for understanding the invention shown; in particular, the part of the Turbomachine or other of its details etc. shown.

Way of carrying out the invention

In a turbomachine 1 with a housing 2 , in which a rotor 4 is mounted and which contains the peripheral assemblies, such as combustion chambers, cooling systems, etc., an annular support structure 3 is provided in the housing 2 . This annular support structure 3 is rotatably mounted in the housing and can be locked in at least one position. All modules 5 to be checked or replaced periodically are mounted on it. In order to be able to rotate the ring-shaped support structure 3 when required during a revision of the turbomachine 1 into different assembly or revision positions, it is connected to a device which, on the one hand, locks the ring-shaped support structure 3 in the operating position and, on the other hand, it into the required assembly or revision positions emotional. This device for rotating the annular support structure 3 is arranged between the housing 2 and the annular support structure 3 or between the latter and the rotor 4 . The housing 2 of the turbo machine 1 has at least one lockable mounting opening 6 , which has such a size and shape that the assemblies 5 to be checked or replaced of the turbomachine 1 are easily accessible or can be removed and removed. In particular, in the case of a plurality of assembly openings 6, these are arranged essentially in two axially normal planes, which correspond to the assemblies 5 present in the interior of the housing 2 . This ensures that the assemblies 5 of the turbomachine are accessible, which significantly reduces the downtime. In addition, in the case of a turbomachine designed in this way, the housing no longer has to be partially dismantled in order to gain access to the assemblies 5 to be replaced or checked. This leads to significant savings in the revision.
