PUMP HYDROELECTRIC UNIT Russian patent published in 2018 - IPC F04D13/04 F03B13/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to pump hydroelectric units. Pump hydroelectric unit contains a centrifugal pump and a propeller hydro-turbine, which are mounted on a common shaft. Propeller hydro turbine is equipped with a frustum coupled in a smaller section with a cylinder in which the propeller hydro turbine is mounted. Suction nozzle of the centrifugal pump is facing the propeller turbine. Shaft along the ends is mounted in angular contact bearings, the sockets of which are mounted on the lateral surface of the cylinder by radial spokes. In the equilibrium plane of the hydraulic unit, bushings are mounted outside the cylinder, through which the support posts pass, on which a gate with drums for cables, with which the hydraulic unit is suspended, is mounted on top.

EFFECT: invention is aimed at improving efficiency, ensuring nominal performance when supplying water to the consumer.
