Abstract
The utility model provides a gas compressor casing for a gas turbine. The gas compressor casing for the gas turbine comprises a gas compressor casing shell body formed in a casting mode, wherein the gas compressor casing shell body is in a round barrel shape, and the thickness of the wall of the gas compressor casing shell body is 10-13 mm. According to the gas compressor casing for the gas turbine, the gas compressor casing shell body is formed in a casting mode, the thickness of the wall of the gas compressor casing shell body is 10-13 mm, compared with a shell body formed by metal plates, the thickness of the wall of the gas compressor casing shell body is increased, the total weight is increased, so that the vibration of the gas turbine utilizing the gas compressor casing shell body is reduced, the deformation of the gas turbine is reduced, and the gas turbine works more stably. A casting part is relatively long in service life and does not crack easily in the use process, so that compared with the shell body formed by metal plates, the gas compressor casing shell body formed in the casting mode does not crack easily and is long in service life.
Description
Technical field
The utility model relates to engine art, especially, relates to a kind of gas turbine with the casing of calming the anger.
Background technique
At present, often the engine modification that uses on aircraft is the gas turbine that is used on ground generating electricity, the gas turbine after remodeling is still continued to use panel beating welding casing before its remodeling.The steel plate that panel beating welding casing uses is thin, and the thickness of steel plate is generally 2mm, and the vibration that occurs in the gas turbine using process easily causes the casing distortion, increase the wearing and tearing between itself and adjacent component surface of contact; Simultaneously, because the site surrounding that gas turbine uses is comparatively abominable, and the working life of steel itself is limited, thereby causes the panel beating casing problem that ftractures easily to occur.
In prior art, on casing, the position of distortion and wearing and tearing is generally two end faces of casing and the faying surface of casing itself (casing comprises the first semicircle casing and the second semicircle casing, during use, fit in the edge of the edge of the first semicircle casing and the second semicircle casing), in such cases, the general method that adopts spraying is repaired two end faces of casing and the faying surface of the first semicircle casing and the second semicircle casing, make surface size after spraying greater than specified value, and then the surface Machining after spraying to specified value; When cracking phenomena appears in the panel beating casing, generally adopt argon arc welding to carry out repair welding to the cracking place, crackle is plugged.
No matter that end face or faying surface to the panel beating casing sprays or adopt the argon arc welding fracture to carry out repair welding, all can only continue the working life of panel beating casing, and can not fundamentally address these problems, and along with the continuation of panel beating casing is used, the problem of distortion, wearing and tearing and cracking will continue to occur, and later each difficulty of repairing is with increasing.
The model utility content
The utility model aims to provide a kind of gas turbine that is out of shape little, working stability, not easy to crack and long service life with the casing of calming the anger, with solve existing panel beating casing distortion and wearing and tearing greatly, easily cracking and working life short technical problem.
For achieving the above object, the utility model provides a kind of gas turbine with the casing of calming the anger, and comprises the wheel chamber casing of casting, and it is cylindric that wheel chamber casing is, and its wall thickness is 10 ~ 13mm.
Further, the wall thickness of wheel chamber casing is 10mm.
Further, the material of wheel chamber casing is Martensitic Stain Less Steel.
Further, shown in wheel chamber casing comprise the first semicircle housing and the second semicircle housing that is arranged symmetrically with along its axis, the edge of the first semicircle housing is by the edge applying of screw or bolt and the second semicircle housing.
The utlity model has following beneficial effect:
According to gas turbine of the present utility model with the casing of calming the anger, wheel chamber casing is by the casting technique moulding, and the wall thickness of the wheel chamber casing after casting is 10 ~ 13mm, compare existing housing by sheet-metal formed, the wall thickness of wheel chamber casing has increased, thereby its whole weight has increased, thus adopt the vibration of the gas turbine of this wheel chamber casing to reduce, more stable thereby its distortion will reduce, work; Generally longer because of the working life of foundry goods, and not easy to crack in using process again, therefore the wheel chamber casing of casting is compared existing sheet-metal formed housing, wheel chamber casing is not easy to crack, long service life.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.The below is described in further detail the utility model with reference to figure.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is according to the sectional structure schematic diagram of gas turbine of the present utility model with the casing of calming the anger.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, gas turbine of the present utility model comprises the wheel chamber casing 1 of casting with the casing of calming the anger, and wheel chamber casing 1 is cylindric, and its wall thickness is 10 ~ 13mm.According to gas turbine of the present utility model with the casing of calming the anger, wheel chamber casing 1 is by the casting technique moulding, and the wall thickness of the wheel chamber casing after casting 1 is 10 ~ 13mm, compare existing housing by sheet-metal formed, the wall thickness of wheel chamber casing 1 has increased, thereby its whole weight has increased, thus adopt the vibration of the gas turbine of this wheel chamber casing 1 to reduce, more stable thereby its distortion will reduce, work; Generally longer because of the working life of foundry goods, and not easy to crack in using process again, therefore the wheel chamber casing 1 of casting is compared existing sheet-metal formed housing, wheel chamber casing 1 is not easy to crack, long service life.
In actual production, at the various pipelines of the outside installation of gas turbine, be subjected to the restriction of gas turbine space outerpace size due to needs, the wall thickness of wheel chamber casing 1 is unsuitable blocked up, and preferably, the wall thickness of wheel chamber casing 1 is generally 10mm.
