Axial Flow Turbine Kaplan Hydro Turbine / Kaplan Water Turbine for
Water Head 2m - 70m Hydropower Project
1. Water head: from 2m --- 70m
2. Power: 0.1MW --- 30MW
3. Frequency: 50/ 60hz
4. Output Type: 0.4KV, 3.3KV, 6.3KV, or 10.5KV AC three phase,
If you are interested in the Kaplan turbine, you should have some
key parameters (such as net head, flow discharge, unit number,
frequency, voltage) in inquiry.
Kaplan Turbine Descrition:
The Kaplan (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
Generally, Kaplan turbine is composed of distributor, guide vane,
runner, draft tube etc.
Main Structure of Kaplan Water Turbine
This hydraulic turbine is axial flow turbine with a vertical shaft.
And its spiral case is made of metal or concrete.
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
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
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
- Draft tube assembly
- Rotating parts assembly
- The distributor assembly
