The Pelton turbine is an additional unit (FR-002) which is attached to the Base Unit for Turbines trainer. The unit illustrate the operating behavior of Pelton turbines and deriving its characteristic variables.
- The unit provides the basic experiments to determine how the Pelton turbine operate, and the most important characteristic variables of it.
- The educational unit consists of a Pelton wheel and a needle nozzle, mounted in a transparent housing.
- The impulse of the water jet is transmitted to the Pelton wheel.
- The needle nozzle can be adjusted during operation.
- The loading device is outside of the housing.
- The eddy current brake generates a defined load. The eddy current brake is specially developed by Bedo. It is wearfree and can be finely adjusted.
- 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 for turbines.
- The water supply and the flow rate measurement are realized with the base unit for turbines.
- A pressure sensor included in the base unit for turbines enables the recording of characteristics at a constant head.
