AXIAL HYDRAULIC TURBINE Russian patent published in 2009 - IPC F03B3/00 F03B13/00 

FIELD: power engineering.

SUBSTANCE: axial hydraulic turbine comprises guide vane block, vanes 1 of which, being made as curved and inverted in direction of impeller rotation, are fixed with the possibility of rotation, impeller installed in chamber 2, with blades 3 of curvilinear shape, fixed in body 4, installed on shaft 5, water supply and water drain parts 6 and 7. Guide vane block is made of coaxially arranged external and internal bodies 8 and 9 and blades 1, with their some ends fixed on internal body 8, and with the other ends - connected to external body 9 with the help of threaded joints with the possibility of rotation. Blades 3 of impeller are fixed on its body 4 by means of threaded joint with the possibility of rotation. Chamber 2 of impeller is connected with its one end to water drain part 7, and with its other end - to external body 8 of guide vane block attached to water supply part 6 of curvilinear shape, and body 4 of impeller is connected to internal body 9 of guide vane block installed on shaft 5. At the same time shaft 5 is located horizontally relative to plane of impeller rotation, is installed by means of bearing units 13 on supports 14, fixed in frame 15, and may be connected to asynchronous motor 17.

EFFECT: simplified design, expansion of operational resources and reduced labour intensity of manufacturing with preservation of high efficiency factor of axial turbine.
