Description
Technical field
The invention belongs to field of fluid machinery, and in particular to a kind of tubular multi-state runner light bulb integral type turbine.
Background technique
In order to meet the needs of different, hydroenergy storage station and tidal power station turbine are all run under various working.It draws water
Storage station is most reliable, most economical, life cycle is long, capacity is big, technology is most mature energy storage device in electric system, is new
The important component of energy development.Tide energy efficiently, cleaning, can large-scale development application, the increasingly favor by various countries.
China's tidal engery resource is abundant, and be richly stored in about more than 32000 kilometers of coastline tidal engery resource altogether.Tide energy has
Unique advantage: low-carbon environment-friendly, free from environmental pollution, resourceful, storage level is big, safe and reliable at low cost, renewable.
Its main feature of Bulb Turbine Units has compact-sized, the good efficiency of stability, and higher to be suitable for low water head big-and-middle
It is also suitable for making Reversible Pump-Turbine operation, since inlet and outlet channel does not take a sudden turn in type power station, pumping operation mode and water
Turbine operating condition can obtain preferable hydraulic performance, applied to can have on tidal power station two-way power generation, it is two-way draw water with it is two-way
Six kinds of functions such as sluicing, therefore be well suited for developing and using Tide resource.In recent ten years, Chinese hydroenergy storage station is sent out rapidly
Exhibition requires multi-state pump turbine also higher and higher.
Although way traffic mode can provide more continuous electric power, there is stronger grid adaptability, peak regulation fortune can be carried out
Row, but construction investment is higher.Change at present due to generating efficiency with the variation of head, and inverted running or as plugman
When making, efficiency is very low, and the unit price of every kilowatt of low-head operating can rise.The prior art mainly passes through the optimization hydraulic turbine

Runner and guide vane design rely primarily on foreign countries, on optimization bulb, reduce light bulb than correspondingly increasing motor installation
Difficulty.So it is necessary to some design studies are done in Bulb Turbine Units structure.
Six operating condition of one kind, the three blade rotary wheel bidirectional tidal that patent publication No. is CN105604776A in the prior art generates electricity
The hydraulic turbine designs guide vane shape, using completely new Guide vane profile, makes to flow more smooth, the resistance in runner
Loss is smaller to be reduced to 3 by 4 for runner blade the piece number, improves the inflow-rate of water turbine of unit, while having carried out to runner bucket excellent
Change design, using type runner bucket, new thickness change rule is used from import to outlet, guarantees positive and negative two-way hydraulic turbine fortune
Efficiency all with higher when row, but it is substantially still optimized for the Hydraulic Design, do not carry out in structure
Change, effect are unobvious；
One kind of Publication No. CN206495745U is small-sized in the prior art self-contained turns paddle scaled bulb tubular hydraulic generator
Group mounting structure, monoblock type turn to be equipped with integral lifting hook, power station water channel base at the top of paddle bulb tubular hydraulic generating set
It is equipped with hoisting platform above plinth and crane installs support column, crane installs support column and is equipped with hoisting traveling crane utility model power station
As long as lesser hoisting platform and hoisting traveling crane are set in, it will be able to which quick and convenient installation is small-sized self-contained to turn paddle scaled bulb tubular water
The foundation construction project amount of turbine generator group, power station is small, easy to install and use, can reduce operating cost, improves economic effect
Benefit.But its purpose is convenient just for installation and repairing, there is no the hydraulic performances for promoting unit.
