Problems solved by technology
[0003] Currently used water turbines, especially small water turbines, generally have the disadvantage of low water kinetic energy collection efficiency, resulting in low conversion rate of electric energy, and the unconverted kinetic energy is easy to impact the water turbine impeller, resulting in damage to the impeller. Moreover, the water flow in the water turbine volute Lack of regular guidance, easy to generate turbulent flow, which further aggravates the low degree of power conversion rate

The invention provides a high-efficiency water turbine impeller. The high-efficiency water turbine impeller comprises an impeller main body. The impeller main body comprises a mounting plate and blades. The six blades are arranged. Each blade comprises a first arc section and a second arc section. The cross section of a push plate is in a triangular shape, and the push plate comprises a first edge, a second edge and a third edge. The high-efficiency water turbine impeller is simple in structure and reasonable in design, the double-arc-shaped design is adopted by the blades, the kinetic energycollection efficiency of a water turbine can be effectively improved, meanwhile, by arranging the push plate, water flow direction can be regulated, the turbulence intensity in a volute can be relieved, the water flow discharging efficiency is improved, and thus the electric energy conversion efficiency of the water turbine is improved.
Description
technical field [0001] The invention relates to a water turbine impeller, in particular to a high-efficiency water turbine impeller. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy, and it belongs to the turbomachinery in fluid machinery. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, the water in the upstream reservoir is led to the turbine through the diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. [0003] Currently used water turbines, especially small water turbines, generally have the disadvantage of low water kinetic energy collection efficiency, resulting in low conversion rate of electric energy, and the unconverted kinetic energy is easy to impact the water turbine impeller, resulting in damage to the impeller. Moreover, the water ...
