Description
Technical field
The utility model relates to a kind of water turbine, and one can utilize potential energy, kinetic energy, pressure energy specifically, adapts to high low water head and saves water flow and improve the Novel flushing pressure type water turbine of mechanical efficiency.
Background technique
Current known water turbine can be divided into reaction turbine and the large class of impulse turbine two:
Reaction turbine: runner utilizes pressure energy and the kinetic energy acting of current.It is characterized in that: pressure flow is full of the whole runner of water turbine, current are subject to the effect of blade when flowing through runner bucket and change the size and Orientation of pressure, flow velocity, current produce pressure difference at runner bucket positive and negative simultaneously, reaction force is produced to runner, forming running torque makes runner rotate, therefore is called impact.Reaction turbine flows through the difference in runner direction by current and adapts to the needs of different head and flow, is divided into again mixed-flow, axial flow, diagonal flow type and tubular four kinds of patterns.
Impulse turbine: runner only utilizes water flow dynamic energy to do work.It is characterized in that: pressure water stream first forms high speed free jet through nozzle, change pressure energy into kinetic energy and impact runner rotation, therefore being called impact type.Interior current only impact part runner at one time, and current are the whole runners not being full of water turbine, and runner just part water inlet, runner under atmospheric pressure works.For adapting to the needs of water flow dynamic energy acting, impact runner blade is generally lobate in bucket.Impulse turbine is divided into again water bucket type (cutting the formula of hitting), tilt-impulse type and double click type three kinds of patterns by the direction difference of jet impulse runner bucket.
One, reaction turbine exists shortcoming has:
Pressure flow is full of the whole runner of water turbine, though current flow through in spiral case stator water conservancy diversion, but produces water turbulence, causes acting loss, can not make smooth in water flow jet as impulse turbine.Therefore only make use of pressure energy, underuse kinetic energy; During runner rotating speed height, current do not do work completely and just and then flow away, and when runner rotating speed is low, current, because being stopped, freely get out between runner bucket.Even if rotating speed gets intermediate value, current still have not acting completely to flow away, and these all cause the loss of acting and the loss of water flow; In large-scale water turbine, manufacturing of runner science and technology gold content is the highest, and it is the most difficult to make, and cost is the highest; There is cavitation, lift machine, fly phenomenon of escaping.
Two, impulse turbine exists shortcoming has:
Only make use of kinetic energy, do not utilize pressure energy, spilt time on high-speed jet impact to bucket leaf, power is disperseed unloading, causes acting loss and water flow loss.
Three, the water level of general reservoir or rivers has high, medium and low three kinds of periods, and wet season savings water is many, and water level is also high, at ordinary times middle water level, and it is few that dry season saves water, and water level is also low; If when deacclimatizing this three kinds of heads by generator merely, water resource waste certainly will be caused, and acting also has loss, if put different types of machines there, deacclimatize different water levels, cause high cost again, Operation and Maintenance can not be unified, increase more multi-specialized personnel and remove Operation and Maintenance, more multioperation maintenance knowledge etc. be known.
