Parher hydraulic manifold block large-scale wind power generation equipment

Is working on 30 to 50 meters high rotating machinery on top of the tower. Rotor diameter of 24 to 56 meters. Due to the vagaries of wind speed and wind direction, wind wheel must hydraulic quick couplers always be aligned with the wind to get the maximum energy. In order to become a steady wind energy into the grid, subject to constant fan speed and prevent speeding coaster. To this end, the basic composition of modern wind turbines by the gearbox, yaw system, hydraulic systems, brake systems and control systems and other components. Acting hydraulic system is pressure valves under the control of the computer to complete the wind turbine blade pitch adjustment moments (or tip adjustment), yaw damping system action and braking systems and control systems, parking brake and other state control. Parher hydraulic manifold block approval of the project for the Science and Technology Bureau of Shenyang City project of new product development program, the results of the project to apply to quick coupling fittings more large 300KW grid miniature hydraulic integrated control system. Achievement characteristics: high-level system pressure, flow. Control requirements can be adapted to a variety of wind turbines; regulator valve manifold group and the control group manifold independent settings, you can set the function of the valve block expansion of the system by changing the control. Control valve manifold in line with international standards of installation pore size, and set the high-precision high-pressure filter at its inlet. The switch can be easily converted to a directional valve type electro-hydraulic proportional directional control valve or servo valve to achieve proportional and servo control.
