Abstract
A kind of high-sealed guide vanes of water turbine axle, relates to a kind of guide vanes of water turbine axle accessory, especially a kind of guide vanes of water turbine axle sealing structure.Comprise stator axis body, it is characterized in that: to have got on the bus at least one place annulate shaft groove at stator axis body, first place's groove requires from diffuser within 10mm, at groove, seal ring is installed, guide vane teunnion is fixed on water turbine by guide vane teunnion pressing plate, guide vane teunnion pressing plate and guide vane teunnion and water wheels body contacting point are also provided with seal ring, to reach watertight effect.
Description
Technical field
The utility model relates to a kind of guide vanes of water turbine axle accessory, especially a kind of guide vanes of water turbine axle sealing structure.
Background technique
Guide vanes of water turbine shaft sealing is exactly a subject matter of puzzlement water power plant and main engine factory throughout the year always, some power station is not also to the repair time, because guide vane teunnion sealing place is leaked seriously, decrease exerting oneself and fluctuation of service of unit on the one hand, the water of seepage can cause unit component to get rusty and affect unit outward appearance on the other hand.Power station is caused to have to overhaul in advance.Common guide vane teunnion sealing has just set up place's seal ring below stator pressing plate, due to stator pressing plate chamfering error, select the model error of seal ring and seal ring itself to wear and tear to cause unit to leak.
Model utility content
The utility model object, for existing water turbine technology, provides a kind of high-sealed guide vanes of water turbine axle, can be overcome solve above-mentioned seepy question by local improvement structure.
Technical solutions of the utility model are a kind of high-sealed guide vanes of water turbine axles, comprise stator axis body, it is characterized in that: to have got on the bus at least one place annulate shaft groove at stator axis body, first place's groove requires from diffuser within 10mm, at groove, seal ring is installed, guide vane teunnion is fixed on water turbine by guide vane teunnion pressing plate, and guide vane teunnion pressing plate and guide vane teunnion and water wheels body contacting point are also provided with seal ring, to reach watertight effect.
Further described groove is preferably provided with three places.
The utility model beneficial effect is:
1. reach multi-sealed effect by increase by three place groove;
2. by the inconsistent effect playing labyrinth seal of increase by three place's groove and guide shaft axle sleeve gap;
3. the effect of shelves sand is also played in first place's sealing place, prevents sand from leaking in guide vane teunnion and stator axle sleeve wear and tear guide vane teunnion and stator axle sleeve.
Improve rear guide vane axle sealing structure, guide vane teunnion position seals is good, can not leak, and runs bring good result to power station.
Be described further with specific embodiment and accompanying drawing below
Accompanying drawing illustrates: Fig. 1 is the utility model installment state schematic diagram in water turbine
Fig. 2 is the utility model installment state A place partial enlarged drawing
Fig. 3 is enlarged diagram together with the utility model guide vane teunnion is installed with diffuser
In figure: guide vane teunnion 1, guide vane teunnion pressing plate 2, stator axle sleeve 3, stator O RunddichtringO 4, diffuser 5, groove 6.
Embodiment
Guide vane teunnion in figure, sealing configuration requires from diffuser 5 within 10mm at guide vane teunnion 1 three place's groove 6, first place grooves of having got on the bus, and is provided with seal ring, reaches watertight effect at this groove 6 place of three places.
Claims (1)
1. a high-sealed guide vanes of water turbine axle, comprise stator axis body, it is characterized in that: install the groove of seal ring at get on the bus at least one place annulate shaft of stator axis body, in described groove, first place's groove is from diffuser within 10mm, and stator axis body three place's annulate shafts of getting on the bus install the groove of seal rings.
