Description:

• A centrifugal pump and a flow control valve for adjusting the inlet pressure.
• The transparent operating area of the turbine enables an optimal view of water flow, rotor and guide vanes during operation.
• By adjusting the guide vanes the angle of attack, the cross-section and thus the output of the turbine are changed. An asynchronous machine is used as a generator for loading the turbine.
• The generator is equipped with a pendulum bearing and with a force sensor to determine the torque.
• A pump with variable speed via frequency converter provides for an energy efficient operation.
• The measured values are displayed digitally and can be processed further on a PC.
• The speed of the turbine is recorded by means of an inductive, non-contact position sensor at the generator shaft.
• The pressures at the inlet and outlet of the turbine, the temperature and the flow rate are recorded by sensors.
