Description
Technical field
The utility model relates to a kind of water turbine, particularly relates to water turbine runner bucket gas supplementary structure.
Background technique
Air supplement of turbine is the essential condition ensureing Hydropower Unit stable operation, and what air supplement of turbine was conventional has several pattern, as short tube tonifying Qi, Francis turbine, alignment of shafts tonifying Qi etc.The air supplement of turbine of traditional form is generally inducer air or pressurized air being mended draft tube.In use expose several respects problem successively: short tube tonifying Qi fills near turbine draft tube arm by air or pressurized air, tonifying Qi DeGrain in operation; Francis turbine air is mended draft tube import center and cross radial distance draft tube tube wall 1/4th place, and Francis turbine device mounting process is complicated, be not easy to inspection and maintenance, sometimes easily washed out by current in operation; Alignment of shafts tonifying Qi is by replenish air to draft cone place, air is not mended runner bucket cavitation zone, tonifying Qi poor effect.
Summary of the invention
The utility model object is, solve the deficiencies in the prior art, there is provided a kind of structure simple, reasonable in design, air directly adds to the cavitation zone of runner bucket, and tonifying Qi is effective, guarantees Hydropower Unit stable operation, life-saving, uses safer water turbine runner bucket gas supplementary structure.
Water turbine runner bucket gas supplementary structure of the present utility model, hydraulic turbine main shaft is connected by its lower flange and rotary wheel of water turbine, it is characterized in that: on hydraulic turbine main shaft, center hole is set, center blowdown pipe is built-in with at center hole, the upper flange of hydraulic turbine main shaft arranges horizontal inlet hole, the inner of horizontal inlet hole is communicated with center blowdown pipe, the check valve that the horizontal outer end of inlet hole and the outer rim of hydraulic turbine main shaft flange are arranged is connected, center blowdown pipe is fixed on the upper bracket of upper end setting in hydraulic turbine main shaft axis hole and the lower support frame of lower end setting, all outlet pipe is equipped with in each runner bucket back side water outlet rim grooves, described check valve, horizontal inlet hole, center blowdown pipe, the outlet pipe of each runner bucket is communicated with successively, the outlet pipe being positioned at each runner bucket cavitation zone arranges several vertical row pores, several vertical row pores are towards the cavitation zone of runner bucket.
Water turbine runner bucket gas supplementary structure of the present utility model can carry out tonifying Qi to the cavitation position of runner bucket, rise and eliminate or alleviate runner bucket cavitation, eliminate runner bucket back side outlet edge vacuum, reduce pressure fluctuation in draft tube of water turbine, in hydraulic turbine operation, vacuum is there is near the outlet edge of the turbine runner blade back side, during blade generation cavitation, the check valve of the upper flange outer rim of hydraulic turbine main shaft is opened automatically, air is by the horizontal tonifying Qi hole of upper flange, center blowdown pipe arrives the cavitation zone near the outlet edge of the runner bucket back side, to the district's tonifying Qi of runner bucket cavitation, when near the outlet edge of the turbine runner blade back side, cavitation does not occur for vacuum expendable pattern, blade, the check valve of the upper flange outer rim of hydraulic turbine main shaft is closed automatically, stop to the district's tonifying Qi of runner bucket cavitation.Its structure is simple, reasonable in design, and air directly adds to the cavitation zone of runner bucket, and tonifying Qi is effective, guarantees Hydropower Unit stable operation, life-saving, uses safer.
Accompanying drawing explanation
Fig. 1 is water turbine runner bucket gas supplementary structure schematic diagram of the present utility model;
Fig. 2 is local K enlarged diagram in Fig. 1;
Fig. 3 is A-A cross-sectional schematic in Fig. 1;

In figure: 1 outlet pipe, 2 runner buckets, 4 rotary wheel of water turbine, 5 lower support frames, 6 center blowdown pipes, 7 hydraulic turbine main shafts, 8 check valves, 9 horizontal inlet holes, 10 upper brackets, 11 vertical row pores.
Embodiment
Below in conjunction with accompanying drawing, water turbine runner bucket gas supplementary structure of the present utility model is described in further detail.
Please refer to Fig. 1-Fig. 4, the hydraulic turbine main shaft 7 of water turbine runner bucket gas supplementary structure of the present utility model is connected by its lower flange and rotary wheel of water turbine 4, hydraulic turbine main shaft 7 arranges center hole, center blowdown pipe 6 is built-in with at center hole, the upper flange of hydraulic turbine main shaft 7 arranges horizontal inlet hole 9, the inner of horizontal inlet hole 9 is communicated with center blowdown pipe 6, the check valve 8 that the horizontal outer end of inlet hole 9 and the outer rim of hydraulic turbine main shaft 7 flange are arranged is connected, center blowdown pipe 6 is fixed on the upper bracket 10 of upper end setting in hydraulic turbine main shaft 7 axis hole and the lower support frame 5 of lower end setting, outlet pipe 1 is all equipped with in the rim grooves of each runner bucket 2, described check valve 8, horizontal inlet hole 9, center blowdown pipe 6, the outlet pipe 1 of each runner bucket is communicated with successively, the outlet pipe 1 being positioned at each runner bucket 2 cavitation zone arranges several vertical row pores 11, several vertical row pores 11 are towards the cavitation zone of runner bucket 2.
In hydraulic turbine operation, vacuum is there is near the outlet edge of runner bucket 2 back side, when making runner bucket 2 that cavitation occur, the check valve 8 of the upper flange outer rim of hydraulic turbine main shaft 7 is opened automatically, air arrives the tonifying Qi hole 11 near the outlet edge of the runner bucket back side, to the district's tonifying Qi of runner bucket cavitation by the horizontal tonifying Qi hole 9 of flange, center blowdown pipe 6; The cavitation district tonifying Qi that when cavitation does not occur for vacuum expendable pattern, runner bucket 2 near the outlet edge of runner bucket 2 back side, the check valve 8 of the upper flange outer rim of hydraulic turbine main shaft 7 is closed automatically, stop to runner bucket 2.Like this, the advantage had in terms of existing technologies is, structure is simple, reasonable in design, and it is effective that air mends the cavitation district, the tonifying Qi that directly add to runner bucket 2, and overall operation is more stable, it is safer to use.
Embodiment of the present utility model is only a specific example; but can not as protection domain of the present utility model; every according to the change of the equivalence done by design spirit in the utility model or to modify or equal proportion zooms in or out, all should think and fall into protection domain of the present utility model.
