Runner diameters: 0.6-3m
Suitable water head: H=3-30m
Capacity of the generator unit: 160-20000kw
The speed range of the turbine: 60-750rpm
* The propeller type is with a vertical axle and fixed runner,
blade angle can not be changed during operation mode, the
efficiency curve is steep and this type is generally suitable for
power station that has water head with slight change or its
operating units can be adjusted according to actual load change.
* The Kaplan type is with adjustable runner controlled by oil
servomotor and moved according to the load/head change to ensure
higher average efficiency, the efficiency of some Kaplan turbine is
higher than 94%.
ADDNEW's Kaplan Hydro Turbines (Propeller Turbines) is widely used
in hydro power stations for the small load and water head changing
or low head.
