The Pelton turbine is an additional unit 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.
