Mechanical speed governor for use in hydroelectric power plant
专利汇可以提供Mechanical speed governor for use in hydroelectric power plant专利检索，专利查询，专利分析的服务。并且PURPOSE:To facilitate operation of coupling a plurality of water turbines, by enabling to fix the opening of guide vanes at a predetermined position when a signal for fixing the opening of a hydraulic servomotor used for opening and closing the guide vanes is applied, without affecting operation of the hydraulic servomotor against change in the speed or rotation of the water turbines. CONSTITUTION:In a mechanical speed governor of this invention, the opening of guide vanes of a water turbine is controlled by operating a first three-way valve 3 by a speeder 2 for detecting change in the speed of rotation of the water turbine and applying a guide vane opening and closing hydraulic signal given from the valve 3 to a hydraulic servomotor 1 via a second three-way valve 4. The opening of said hydraulic servomotor 1 is controlled to be smaller than a predetermined value by a load restricting means 6. The mechanical speed governor of this invention comprises a relief valve 18 which is actuated by a lever 7 connecting the above two valves 3, 4, a lever 8 connecting the load restricting means 6 and the valve 3, and the hydraulic servomotor 1. Further, the apparatus of this invention comprises a two-way valve 19 which intercepts the hydraulic signal applied from the valve 3 to the valve 4 and applies the hydraulic signal given from the relief valve 18 to the valve 4.，下面是Mechanical speed governor for use in hydroelectric power plant专利的具体信息内容。
