 0.1MW - 30MW Low Head Kaplan Hydro Turbine / Kaplan Water turbine with Fixed Blades/ Adjustable Blades




The Kaplan Turbine(axial-flow turbine) for low head from 2m to 70m. This type of turbine is mostly suitable for hydropower stations with low water head and big flow.

lts feature is that the water flow passes through the runner axially. The axial-flow turbine can be classified into two forms according to the runner construction: one is fixed blades (Propeller) for small variation of head and power, the other is movable blades (Kaplan) for large variation of head and power.

The kaplan turbine with vertical shaft arrangement , with three types as open flume, pressure flume, and seal off (concrete spiral case).


Generally, Kaplan turbine is composed of distributor, guide vane, runner, draft tube etc.  


The water flows through the channeling pipe, and then into the spiral case, which ensure that the water enter the turbine circumferentially and symmetrically, forming certain circumfluence quantum. 
The water flows through the stay ring into the distributor, whose guide vanes can regulate the turbine discharge and the flow direction and thus make the water flow into the runner circumferentially and symmetrically. Consequently, the runner revolves and converts hydraulic energy into mechanical energy and then drives the rotor of the generator revolve by the force of the main shaft of the hydraulic turbine, thus converting the mechanical energy into electrical energy. The water, which has gotten out of the runner, flows to the downstream of river through the draft tube.
Because of the restoration of the draft tube, the energy of the water flowing out of the outlet, is partly reused, thus loss is reduced and efficiency is improved,


Main structures of the hydraulic turbine are described in the following.

  • Draft tube assembly
  • Rotating parts assembly
  • The distributor assembly




1.     Water head: from 2---70m

2.      Power: 0.1MW-----30MW 

3.     Frequency: 50/ 60hz
