DESCRIPTION
Servo valve G761-3033B is a long-term spare part used in power plants. The action of the servo valve corresponds to the input current, so a high internal resistance amplifier must be used. This can minimize the impact of coil mutual inductance and coil impedance changes on the current. The four leads of the torque motor inside the G761-3033B servo valve are all located at the socket, so the torque motor coil can be externally connected in series, parallel, or single coil operation.
If the fasteners of Servo valve G761-3033B are loose, the installation screws should be checked to see if they are not tightened in place or if the anti loosening design is not in place. It can cause an increase in zero deviation and may cause servo valve failure.
Working Principle OF servo valve G761-3033B
The working principle of the electrohydraulic Servo valve G761-3033B: If there is an electrical signal input, the armature drives the baffle to rotate, and the baffle is close to the nozzle, reducing the oil discharge area and flow rate of the nozzle, and increasing the oil pressure in front of the nozzle; Otherwise, the oil pressure in front of the nozzle decreases, causing the original electrical signal to be converted into a torque signal, resulting in a mechanical displacement signal that is then converted into an oil pressure signal.
