Description
Technical field
The present invention relates to a kind of turbine impeller, more particularly to a kind of high-efficiency water turbine impeller.
Background technology
The hydraulic turbine is the dynamic power machine for the energy of current being converted to rotating mechanical energy, it belongs to the turbine in fluid machinery
Machinery.The modern hydraulic turbine is then most of to be mounted in power station, for driving electrical power generators.In power station, upper pond
In water guide the hydraulic turbine into through aqueduct, promote rotary wheel of water turbine rotation, drive electrical power generators.
The hydraulic turbine now used, particularly small hydraulic turbine, commonly there are water flow dynamic energy collection efficiency it is not high the shortcomings that,
Cause electric energy conversion ratio relatively low, the unconverted easy impulse water turbine impeller of kinetic energy causes impeller failure, moreover, hydraulic turbine snail
Current in shell lack regular guiding, easily generate sinuous flow, have more aggravated the relatively low degree of electric energy conversion ratio.
The content of the invention
In view of the above-mentioned problems, the present invention proposes a kind of high-efficiency water turbine impeller.
Specific technical solution is as follows：
A kind of high-efficiency water turbine impeller, including impeller bodies, which is characterized in that the impeller bodies include installing plate and
Blade, the installing plate is rounded, and the blade is fixedly welded on the upper surface of installing plate, and the quantity of blade is 6,6
The circular center of circle that blade is on installing plate, in circumferential uniformly distributed；
The blade is arc-shaped, and including the first arc section and the second arc section, first arc section is arc-shaped, institute
The arc-shaped corresponding central angle for being in is α, and the α is 55~58 °, and second arc section is arc-shaped, the circle for being in
Arc is β in the arc-shaped tangent and corresponding central angle that the first arc section is in, and the β is 58~62 °；
The end of second arc section is equipped with push plate, and the section of the push plate is triangular in shape, the triangle bag for being in
Include while one, while two and side three, arc-shaped tangent, the two and second arc section institute of side that the side one is in the second arc section
The arc-shaped diameter for being on same straight line, it is described while three and while one between angle be γ, the γ be 5~10 °；
Further, the arc-shaped diameter that arc-shaped a diameter of second arc section that first arc section is in is in
Twice.
Beneficial effects of the present invention are：
A kind of high-efficiency water turbine impeller proposed by the present invention, including impeller bodies, impeller bodies include installing plate and leaf
Piece, blade quantity are 6, and including the first arc section and the second arc section, the section of push plate is triangular in shape, including while one, while two
With side three, the configuration of the present invention is simple, design is reasonable, and blade uses double cambered designs, can effectively improve the kinetic energy collecting of the hydraulic turbine
Efficiency, meanwhile, the setting of push plate, can regular flow direction, can not only reduce the sinuous flow intensity in spiral case, and improve the row of current
Go out efficiency, and then improve the electric energy conversion efficiency of the hydraulic turbine.
