FIELD: wind pumps.
SUBSTANCE: invention relates to wind pumps. Wind pump system contains a power wind turbine, kinematically connected through a power shaft and located on it a crank of variable radius of rotation with a rod of the piston pump hinged to the crank pin, the power shaft has a through concentric hole, through which an auxiliary shaft is passed, at one end associated with an auxiliary wind turbine, rotatably mounted on the power shaft, and the other end – gearing with a gear installed on the intermediate axis of the crank, while the crank pin is fixed to the gear with an offset relative to its axis, and the synchronous speed of the auxiliary wind turbine is equal to the speed, at which the wind power utilization factor of the power wind turbine has the maximum value.
EFFECT: invention is aimed at increasing the productivity of a wind pump unit.
