Mixed flow water turbine generator is composed of hydraulic turbine and generator using coupling. Hydraulic turbine is mainly composed of volute, impeller, main shaft, seal and suspension et al. As high pressure fluid is guided through inlet pipe into turbine volute, the fluid would force the impeller to rotate. Electricity is generated when the rotor rotates with respect to the stator.
Mixed flow turbine is horizontally mounted. Its advantages are as follows:
1. Pipe inlet and pipe outlet, which is easy to install;
2. Turbine and generator are separated, which is easy to maintain;
3. Turbine has 2-3 bearings; generator has 2 bearings, which is more reliable;
4. The separate oil lubrication system of turbine ensures a longer life span of bearings.
