HYDRAULIC SET OF HYDROELECTRIC POWER STATION Russian patent published in 2007 - IPC F03B1/00 F03B3/02 

FIELD: hydraulic engineering.

SUBSTANCE: invention is designed for use on hydroelectric power stations with insignificant fluctuation of lower pond level at high head and water flow ranges. According to invention, vertical shaft of set rest through lower end with cone-shaped working surface of frame-step bearing. Pan is hermetically attached to shaft and working wheel, and suction pipes are attached tangentially to pan. Jets from suction pipes are directed to blades of active wheel freely rotating on shaft and transmitting to shaft rotation through speed-up and direction-change reduction gear, parts of which being parts of hydraulic set. Number of pipes is equal to number of blades. Jet are directed to working surfaces of blades under constant effective angle of action. Seals of reaction wheel are made by elastic box-shaped rings contacting through convex side surfaces from opposite sides exposed to pressure of water. Delivery of water to seal from bottom to top prevents getting of solid particles between friction surfaces.

EFFECT: increased speed and efficiency.
