Description
Technical field
The utility model is related 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 flow 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, push rotary wheel of water turbine rotation, drive electrical power generators.
The hydraulic turbine now used, especially small hydraulic turbine commonly have the shortcomings that water flow dynamic energy collection efficiency is not high,
Cause electric energy conversion ratio relatively low, unconverted kinetic energy is easy impulse water turbine impeller, leads to impeller failure, moreover, hydraulic turbine snail
Flow in shell lacks regular guiding, easy tos produce sinuous flow, has more aggravated the lower degree of electric energy conversion ratio.
Utility model content
In view of the above-mentioned problems, the utility model proposes a kind of high-efficiency water turbine impellers.
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 mounting plate and
Blade, the mounting plate is rounded, and the blade is fixedly welded on the upper surface of mounting plate, and the quantity of blade is 6,6
The circular center of circle that blade is in about mounting plate, in circumferential uniformly distributed；
The blade is arc-shaped, including the first arc section and the second arc section, and 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
The arc-shaped tangent and corresponding central angle that arc is in the first arc section is β, 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 packet for being in
Include while one, while two and side three, arc-shaped tangent, the side two and the second arc section institute 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.
The beneficial effects of the utility model are：
The utility model proposes a kind of high-efficiency water turbine impeller, including impeller bodies, impeller bodies include mounting plate
And blade, blade quantity is 6, including the first arc section and the second arc section, and the section of push plate is triangular in shape, including side one,
While two and while three, the utility model is simple in structure, reasonable design, and blade can effectively improve the hydraulic turbine using double cambered designs
Kinetic energy collecting 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 expulsion efficiency of flow, and then improve the electric energy conversion efficiency of the hydraulic turbine.
