The educational unit is designed to illustrate the single-stage axial impulse turbine with a vertical axis. All components necessary for performing experiments are available.

                                     
  • The trainer can be connected to another trainer (Steam Generator) to form steam power plant.
  • The steam required is generated by the steam generator.
  • The turbine can be operated with saturated steam or superheated steam.
  • The steam is expanded in the turbine and condensed through the water-cooled condenser.
  • Load is applied to the turbine by an eddy current brake.
  • The turbine has a non-contact labyrinth seal on the shaft with a sealing steam circuit.
  • The turbine is fitted with various safety devices in order to prevent damage such as by excessively high speed or pressure in the system.
  • The educational unit is equipped with sensors to record the temperature, pressure, and flow rate at all relevant points.
  • Turbine speed and torque are measured electronically at the eddy current brake.
  • The measured values can be read on touch screen. At the same time, the measured values can also be transmitted directly to a PC via USB.
  • The educational unit is supplied with a schematic diagram to demonstrate the system operation.
  • The trainer is supplied with a Bedo software.
