FIELD: machine engineering.
SUBSTANCE: shaftless straight-flow hydraulic turbine includes an impeller, a rim enclosing the ends of impeller blades, a rotor of generator with poles comprising one unit with the rim, a generator stator, a seal on the two sides of the rim. The rim with the rotor and the generator stator are enclosed in a chamber. The chamber has an inlet for compressed air supply with possibility of its feed adjustment, an inlet for pressure sensor in the chamber, a water flow pressure sensor located on the generator chamber. Ends of the rim are provided with circular concentric ridges. An air channel between the impeller rim and the turbine flow part is filled with porous material in form of cellular seals.
EFFECT: improved reliability of shaftless straight-flow hydraulic turbine design.
