Abstract
The utility model relates to a guide blade structure with high abrasion resistance, which comprises a guide blade body, a guide blade water inlet edge and a guide blade water outlet edge, and is characterized in that: a through hole is processed at the guide blade water inlet edge, and an abrasion-resistant stainless steel strip is fixed inside the through groove. The abrasion resistance of the guide blade water inlet edge is greatly improved, the production quality is improved, the running efficiency of the machine unit is ensured, and the service life of the unit is improved.
Description
Technical field
The utility model belongs to the hydro-turbo generator set water guide mechanism technical field, particularly relates to a kind of high wear resistance guide vane structure.
Background technique
The water guide assembling is the big portion of one in a hydraulic turbine generator cover, it mainly comprises several big critical components such as stator, interior outer gate barrel and control ring, pressure ring, stator is wherein of paramount importance parts, and it is installed between the inside and outside ring sparger, a week 16 evenly distributions.In the unit generation running, the flow of the folding of stator control water.It is exactly directly to process into plane, water limit on the stator of cast steel that stator in the past adds man-hour.In the process that stator is installed.Stator water inlet limit and go out that gap between the waterside will reduce as far as possible even very close to each other, but because in the process of unit generation operation, the switch that stator is frequent, can cause the into wearing and tearing on water limit to cause the slit between stator to strengthen gradually, can't control the flow of water better, influence the generating efficiency of unit, shortened the working life of generator set.
Summary of the invention
The utility model provides a kind of high wear resistance guide vane structure of a kind of high wear resistance, high water-proof performance for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of high wear resistance guide vane structure comprises diffuser, and stator water inlet limit, stator go out the waterside, it is characterized in that: the described place, stator water inlet limit that is positioned at is processed with groove, is fixed with the wear resistance stainless steel strip in groove.
Advantage and the good effect that the utlity model has are: because the utility model utilizes wear resistance, the water proofing property of stainless steel, the place is processed with groove on stator water inlet limit, in groove, be fixed with the wear resistance stainless steel strip, improved the wear-resisting property on stator water inlet limit greatly, improved the quality of production, guarantee unit operation efficient, improved the working life of unit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Among the figure: 1, diffuser; 2, stator water inlet limit; 2-1, groove; 3, stator goes out the waterside; 4, stainless steel strip.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment:
See also Fig. 1 and Fig. 2, a kind of high wear resistance guide vane structure, comprise diffuser 1, stator water inlet limit 2, stator goes out waterside 3, the good wear resistance that has owing to stainless steel, water proofing property, therefore the utility model has utilized this performance, 2 places, limit are processed with groove 21 in the stator water inlet, in groove, be fixed with wear resistance stainless steel strip 4, present embodiment is by being welded on by interior the two ends of welding technology with stainless steel strip 4, so the utility model improved the wear-resisting property on stator water inlet limit greatly, improved the quality of production, guarantee unit operation efficient, improved the working life of unit.
