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.

The use of Parher hydraulic valve manifold and classification:
Press the control method of classification: manual, electric, hydraulic control
Classified by function: flow valve (throttle valve, control valve, flow diversion valve), pressure valves (pressure relief valve, pressure reducing valves, sequence valves, unloading valves), directional valve (solenoid valve, manual change to the valve, check valve, check valve)
By installation of: plate valves, valves,metric adapters modular valves, cartridge valves, valve cover [1]
Use is divided into one-way valve and valve. Parher hydraulic valve manifold A check valve: in turn allows only unidirectional fluid conduit, i.e., the reverse cut. Valve: change the pass, breaking the relationship between the different lines. According hose fittings to the spool valve in the number of job positions in the sub-two, three, etc.; according to the number of channels under the control of two-, three, four, five-way, etc.; points manually based on the spool drive, motor, electric , hydraulic, and so on. Figure 2 is a three way valve works. The supply port P, O is the return port,metric bolts A, B is an output port leading to the actuator. When the spool is in the neutral position, all ports off, the actuator does not move; when the spool is moved to the right position, P, and A pass, B and O on; when the spool is moved to the left position, Parher hydraulic valve manifold, and B Tong, A and O on. Thus, the actuator can be positive and reverse movement.
The late 1960s, on the basis of the several hydraulic control valves on and developed the electro-hydraulic proportional control valve. Its output electrical signal (pressure, flow rate) changes continuously with the input energy. Electro-hydraulic proportional control valve according to the role of different, accordingly divided into electro-hydraulic proportional pressure control valves, electro-hydraulic proportional flow control valves and electro-hydraulic proportional directional control valve.

Parher hydraulic cutting machine must be manufactured in accordance with the requirements of
valve with screw connection performance levels must comply with the manufacturer's requirements, not free substitution.Parher hydraulic cutting machine Connection screws should be tightened evenly (do not use a hammer or wrench forcibly twist), Interlock Hose Fittings do not twist side, and finally the mounting surface and bottom valve or manifold monoblock valve mounting surface all contacts.
(2) should be taken back to the oil inlet port and orientation, as will some of the valve inlet port fitted with anti-return oil will cause an accident. Some valves for easy installation, often open with two holes with the role, not the one you want after the installation closure.
