Abstract

A method provides stream guide vane 18 supplement with head conduit 16 from a reach 15 through turbine pit 17, which is allocated in front of it or around impeller. The stream guide vane is twisted towards water impeller rotation and impeller blades 5 lattice consisting of two parts. Blade convex side 9 is directed to inlet stream, and concave side 10 – to impeller rotation. Stream direction changes towards radial direction by means of blades convex sides, when the stream inlets between upper and lower rims on more than 45° sharp angle, stream twisting and its direction to concave sides of opposite blades, opposite of impeller rotation, the stream existed in the impeller rotates to create rotational moment. Water stream overflows into lower reach from impeller through suction tube 19. At that, stream direction is changed by additional blades 13 lattice in front of water outlet in the suction tube. The stream is directed around fairing 12, and by means thereof the rotational moment is changed. The impeller comprises blade lattice consisting of two parts, one wherefrom is created with the blades 5 having curvilinear surfaces disposed between upper and lower rims, and another part is executed on lattice outlet, and is created with blades lower parts 11 bent to lower rim and attached therewith concave sides to the stream; the fairing is attached to upper rim. At that, additional blades 13 lattice is executed on impeller outlet between blades lower parts. Lattice narrow end is connected to fairing, and wide end – to blades lower part; or the blades create bent with lower parts thereto lower rim, and additional blades are executed as one piece from fairing up to blades lower part.
