turbine for a hydroelectric facility, and, hydroelectric facility

摘要

1/1 summary “turbine for a hydrominic power installation, and hydrominic power installation” is provided with a turbine for a hydrominic power installation comprising a hub (430), a plurality of turbine blades (440) provided on the hub (430), a pitch angle adjustment unit (460) coupled to the turbine blades (440) to adjust the pitch angle of the turbine blades, a dual acting hydraulic cylinder (450) and a piston rod (470) connected to it. the piston rod (470) is coupled to the pitch angle adjustment unit (460) in such a way that the pitch angle adjustment unit (460) performs a rotational movement. when the piston rod (470) is moved in the longitudinal direction. the double acting hydraulic cylinder (450) is provided in a coupled hydraulic chamber by means of a first and a second hydraulic line such that the double acting hydraulic cylinder It is displaceable by feeding a hydraulic fluid through the first or second hydraulic line and thus leads to the adjustment of the pitch angle of the turbine blades ( 440) by coupling to plunger rod (470) and pitch angle adjusting unit (460).
