Kaplan Turbine Trainer
Technical Description of Kaplan Turbine Trainer
Water
turbines are turbo machines which convert water energy into mechanical
energy. Mostly, they are used for driving generators for power
generation purposes. The Kaplan turbine is a reaction turbine with an
axial through flow. It has a high specific speed and is suitable for
large water flows and small to medium heads. Therefore, the Kaplan
turbine is used as a "classic" water turbine in run-of-the-river power
stations. The helps to investigate the characteristic behaviour of a
simple-regulated Kaplan turbine during operation. The trainer is
provided with a closed water circuit with tank, submersible pump and
throttle valve for adjusting the flow rate. The angle of incidence and
thus the power output of the impeller are changed by adjusting the guide
vanes. The turbine is loaded with a wear-free eddy current brake. The
speed is captured by means of an inductive, non-contact position sensor
at the turbine shaft. For determining the turbine power, the eddy
current brake is equipped with a force sensor for torque measurement.
