To gradually it is thinning.Such a structure makes the edge of the outer support circle 2 of impeller form sharp sword shape, so as to water flow cutting, reduces impeller
The resistance of rotation.
Further, in above-mentioned Universal water-flow generator, the central raised phase of the blade 6 of the first blade 5 and second
Mutually deviate from.Such a structure make two relative to the upstream face of blade form a cambered surface met to current, so as to more efficiently
Reception current kinetic energy.
Further, in above-mentioned Universal water-flow generator, the rotating shaft is provided with 3 impellers.Such a structure makes multiple
The kinetic energy of impeller only can be converted into electric energy with a generator, reduce production cost.
