Description:

• The turbine torque is determined by force measurement on a band brake and is read on spring balances.
• For measuring the rotational speed, a non-contact speed sensor.
• A manometer shows the water pressure at the turbine inlet.
• Water turbines are turbo machines utilizing waterpower.
• The water is fed in the control device by means of a spiral housing.
• The Francis turbine is part of the reaction turbines, which convert the pressure energy of the water into kinetic energy in the control device and in the impeller.
• The flowing water is accelerated in the control device by the adjustable guide vanes and directed onto the vanes of the impeller.
• The redirection and further acceleration of the water in the impeller generates an impulse, which is transmitted to the Francis wheel.
