Computerized Francis Turbine Trainer
Product Code : EL-TMLE-10684
Quick Answer: The Computerized Francis Turbine Trainer is a lab unit built around a Francis turbine driven by a closed water circuit, letting students study how adjusting the guide vanes changes the turbine's output while an asynchronous machine acting as a generator applies load. A transparent operating area gives a clear view of the water flow, rotor and guide vanes in action, while sensors for pressure, temperature, flow rate, torque and speed feed data that is displayed digitally and can be processed further on a PC. This setup lets students determine the turbine's mechanical and hydraulic power, calculate efficiency, record characteristic curves, and study the conversion of hydraulic into mechanical energy.
The closed water circuit consists of a tank with optional cooling, a centrifugal pump and a flow control valve for adjusting the inlet pressure, while 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, and a pump with variable speed via frequency converter provides for energy-efficient operation.
The speed of the turbine is recorded by means of an inductive, non-contact position sensor at the generator shaft, and the generator is equipped with a pendulum bearing and a force sensor to determine the torque. The pressures at the inlet and outlet of the turbine, the temperature and the flow rate are recorded by sensors, and the measured values are displayed digitally and can be processed further on a PC.
