Gunt - Model HM 150.20 - Hydraulic Turbines - Brochure

Water turbines are turbomachines utilising water power. The Francis turbine is a type of reaction turbine which converts the pressure energy of the water into kinetic energy in the distributor and in the rotor. The water is fed in the distributor by means of a spiral housing. The flowing water is accelerated in the distributor by the adjustable guide vanes and directed onto the blades. The redirection and further acceleration of the water in the rotor generates an impulse which is transmitted to the rotor. HM 150.20 is the model of a Francis turbine demonstrating the function of a reaction turbine.
