IV. Application Areas
• Machine Tools: Used to drive hydraulic cylinders for high-precision machining and positioning.
• Construction Machinery: Such as excavators and cranes, for controlling the movement of actuators.
• Oil Drilling Rigs and Refineries: Provides precise hydraulic control during drilling and refining processes.
• Hospitals and Laboratories: Utilized in medical equipment and experimental devices requiring high-precision hydraulic control.
• Power Plants: Commonly used for precise control of axial flow fans to ensure stable operation of power plant equipment.
V. Working Principle
• Electrical Torque Motor: Receives electrical analog signals and generates linear or rotational motion proportional to the control signal.
• Dual-Nozzle Pilot Stage: Converts the motion of the torque motor into a hydraulic pressure differential, driving the spool valve second stage.
• Spool Valve Second Stage: Controls the direction and flow rate of hydraulic oil based on the pressure differential from the pilot stage, achieving hydraulic amplification and output.
• Mechanical Feedback Mechanism: Provides a force opposite to the torque motor force through a feedback rod and mechanical spring assembly, enabling repeatable proportional motion of the valve spool relative to the electrical signal.
