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.
