FIELD: small hydroelectric power plants. SUBSTANCE: hydroelectric turbine casing 1 accommodates two similar runners 6 installed in parallel opposition. Plates 8 are fitted in radial slots 7 of rotors 6. Butt ends of plates 8 have pins 9. Inner surfaces of head covers 4 have contour followers in the form of grooves 5. Pins 9 are engageable with grooves 5. Streamlined guide 11 is installed in top part of casing 1 between runners 6. EFFECT: improved efficiency due to two runners operating simultaneously and due to water action on plates from top of runners to their bottom. 1 dwge |
