About Experiments With An Action Turbine
EXPERIMENTS WITH AN ACTION TURBINE
- The conversion of pressure energy into kinetic energy in the rotor is characteristic for reaction turbines.
- The experimental unit is placed upon the base unit. The two units together provide the basic experiments to get to know the operating behaviour and the most important characteristic variables of reaction turbines.
- The water jet discharged from the rotor which drives the turbine according to the reaction principle can be observed during operation. This facilitates the understanding of the principle of operation and the underlying laws (eg. momentum). Consists of a rotor mounted in a transparent housing and a loading device outside of the housing. The eddy current brake generates a defined load. The eddy current brake is specially developed. It is wear-free and can be finely adusted.
- The torque delivered by the turbine is determined via an electronic force sensor. The speed is measured with an optical speed sensor. The measuring values are transferred to the base unit.
- The water supply and the flow rate measurement are realised with the base unit. A pressure control included in enables the
- recording of characteristics at a constant head.
- All the advantages of software-supported experiments and evaluation are offered by the software in.
- The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
