Abstract
The utility model relates to a stator pressure ring welding structure for a steam turbine generator, which comprises a stator frame outer wall and a stator pressure ring which are welded mutually, wherein an even number (more than four) of sections of weld joints are arranged between the stator pressure ring and the stator frame outer wall and are uniformly distributed on the stator pressure ring; the length of the weld joints is the same; and slant cuts are processed at the welding parts of the stator frame outer wall and the stator pressure ring. The stator pressure ring welding structure not only guarantees the welding effect of the stator pressure ring and the stator frame outer wall, but also guarantees the laminating quality of a stator core, and also reduces the vibration of a frame, thus well ensuring the insulation of a stator coil.
Description
Technical field
The utility model relates to turbo generator, relates in particular to the Welding Structure of stator of steam turbine generator trim ring.
Background technology
Existing stator of steam turbine generator support generally adopts horizontal support welded-steel plate construction.Out frame is mainly used in fixed iron core, bears and transmit torque, supports parts such as end cap.Stator core press-fits in adopting, and after stator pressing ring and out frame weld, begins to laminate punching, so the welding of stator pressing ring and out frame is very crucial.Conventional welding method is that full weld welds entirely, sometimes stator pressing ring can be out of shape because being heated inequality, final and out frame outer wall can't firm welding, and not prison welding can cause iron core pressure mounting not tight, and vibration strongly during the motor operation, because motor oscillating strengthens, the core tooth part vibration is also very strong, can damage the insulation of stator coil like this, influences the motor runnability, stator pressing ring laminates also and can affect iron core because be out of shape also out-of-flatness.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, provide a kind of make stator pressing ring can with the out frame firm welding, and the Welding Structure of the stator of steam turbine generator trim ring of deformation does not take place.
The technical solution of the utility model is as follows:
A kind of Welding Structure of stator of steam turbine generator trim ring, comprise the out frame outer wall and the stator pressing ring that are welded to each other, the weld seam of described stator pressing ring and out frame outer wall is the even number section more than 4, and described weld seam is distributed on the stator pressing ring, the equal in length of described each weld seam.
Its further technical scheme is: described out frame outer wall and stator pressing ring welding cooperation place all process oblique groove.
And its further technical scheme is: described stator pressing ring adopts steel plate Q235-A to process.
Useful technique effect of the present utility model is:
Welding Structure of the present utility model makes the welding of stator pressing ring and out frame more firm, and deformation does not also take place, thereby reaches good fixed iron core and the purpose of protecting fixed subcoil insulating.

Fig. 2 is the enlarged drawing at out frame outer wall inner ring A place among Fig. 1.
Fig. 3 is that the B of stator pressing ring among Fig. 1 is to view.
Fig. 4 is the cutaway view along C-C line among Fig. 3.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, the utility model comprises out frame outer wall 1 and the stator pressing ring 2 that is welded to each other, and stator pressing ring 2 adopts steel plate Q235-A to process, to guarantee its intensity.Out frame outer wall 1 all processes oblique groove 4 with stator pressing ring 2 welding cooperation places, is convenient to welding.As shown in Figure 2, the inner ring of out frame outer wall 1 is processed into groove obliquely.As shown in Figure 4, the groove under oblique is processed in the outer ring of stator pressing ring 2.
As shown in Figure 3, the weld seam 3 of stator pressing ring 2 and out frame outer wall 1 is the even number section more than 4, and weld seam 3 is distributed on the stator pressing ring 2, the equal in length of each weld seam 3.Weld seam segments, fusion length and weld spacing can be adjusted according to stator pressing ring 2 outer rings size.In the present embodiment out frame outer wall 1 wide with the axial weld seam of stator pressing ring 2 be 2 * 10, welding groove angle is 53 °, band root face V-shaped weld, and the full circle weld seam is divided equally 16 sections (wherein 8 sections only are shown among Fig. 3), every section fusion length is 160mm, and weld spacing is 163mm.
Welding sequence explanation: as shown in Figure 3, during welding, first section 3a of welding welds second section 3b about center of circle symmetry more earlier, the 3rd section 3c, the 4th section 3d weld the 5th section 3e, the 6th section symmetrical successively segmentation welding of 3f...... again about first section 3a, second section 3b symmetry.This welding is heated evenly stator pressing ring 2; can not produce distortion; and firm welding; adopted full weld to weld entirely more in the past; both guaranteed the welding effect of stator pressing ring 2 with support outer wall 1; also guaranteed the quality that laminates of stator core, also reduced the vibration of support, good effect has been played in the insulation of protection stator coil.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection range of the present utility model.
