Embodiment Construction
[0017] like figure 1 As shown, the water turbine is connected to the centrifugal pendulum 1 through a synchronous mechanism, and the rotational speed of the unit is synchronously sensed by the centrifugal pendulum 1. The centrifugal pendulum 1 is connected to the guide vane pressure distribution valve 2 through a lever mechanism, and the guide vane pressure distribution valve 2 is connected to the guide vane servomotor. 3. The oil circuit is connected to control the opening or closing or stopping of the guide vane servomotor 3 through the oil circuit. The guide vane servomotor 3 is used to control the opening of the movable guide vane, and a feedback unit is connected between the guide vane servomotor 3 and the synchronous mechanism; at the same time, the guide vane servomotor 3 is connected sequentially through the displacement sensor 7, the processing unit 8, The electrical association formed by the hydraulic conversion mechanism 9 is electrically connected to the vane press...
