(1) Axial flow type turbine generators series.
(2) Turgo turbine generators series, e.g. vertical type and horizontal type.
(3) Tubular turbine generators series, e.g. Bulb type and shaft extension type.
(4) Francis turbine generators series.
(5) Impulse turbine generators series and double turbine generators series and so on.
1.Francis turbine has the advantages of compact structure, high efficiency and can adapt to a wide range of water head of turbine type. It is one of the widely used around the world;
2.When the water flow through the turbine wheel, it enters to radial, axial flow, so it is also called the radial axial flow turbine;
3.Francis turbine is also called the Francis turbine. The water flow from the surrounding radial inflow runner, then approximate axial flow runner, runner by the crown, under the ring and the blade;
4.It is applicable to the head from a range of 20 meters of up to 700 meters, has the advantages of simple structure, stable operation, and high efficiency, but it is generally used in the head in the range(50 to 400 meters). Single output from tens of KW to several 101000 tile. At present this kind of turbine maximum output has exceeded 700000 kilowatts. A turbine is one of the most extensively used.
