Pelton Turbine Experimental Model
  • Principle of operation of a Pelton turbine
  • Characteristic at constant head
    • Relationship between torque and speed
    • Efficiency dependent on speed
    • Flow rate dependent on speed
    • Hydraulic power and mechanical power dependent on speed
  • Evaluation of measuring values and characteristics based on the theory
  • Partial load behavior with needle control in comparison to throttle control
  • No. of Pelton turbine blades= 20 blade
  • Diameter : 235 mm
  • Torque: 0 .....5Nm
  • Speed : 0.....3000

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.
