The GUNT Operating Principle of a Francis Turbine (HM 150.20) demonstrates the function of a reaction turbine. Water is fed via a spiral housing into the distributor, accelerated by adjustable guide vanes, and directed onto the rotor blades. The redirection and further acceleration of the water in the rotor generates an impulse transmitted to the rotor, converting pressure energy into kinetic energy.
Product Features
- Rotor with distributor and adjustable guide vanes
- Band brake for loading the turbine and torque measurement
- Transparent front panel for observing water flow, rotor, and guide vanes
- Adjustable guide vanes to modify angle of attack and rotor power
- Torque measurement via spring balances
- Rotational speed measurement possible with non-contact sensor (e.g., HM 082)
- Manometer for measuring water pressure at turbine inlet
- Mountable on HM 150 base module with water supply from HM 150 or laboratory supply
Benefits
- Visualises the operation of a Francis reaction turbine clearly
- Allows study of water flow, guide vane adjustment, and energy conversion
- Enables torque and speed measurements for practical learning
- Hands-on understanding of rotor and distributor dynamics
