Technical Specifications Hydraulic oil supply driven by engine; mechanical speed sensing mechanism; adjustable speed droop and speed setpoint. Operating temperature: -20℃ ~ +80℃.
Functional Features Mechanical speed sensing; hydraulic power amplification; adjustable speed setting and droop; over-speed mechanical trip protection.
Application Scenarios Medium speed diesel engine, marine main engine and stationary genset mechanical speed regulation.
Performance Parameters High output torque, reliable hydraulic amplification, stable speed holding performance, strong anti-interference without electronic components.
Structural Characteristics Cast iron housing, built-in flyweight speed sensing assembly, hydraulic valve and power piston, speed adjustment knob on front panel.
Working Principle Engine drives flyweight assembly to sense rotational speed. Speed deviation changes hydraulic valve opening, controlling oil flow to power piston. The piston outputs mechanical movement to adjust fuel rack for speed correction.
Installation Requirements Directly coupled to engine drive shaft; maintain specified hydraulic oil level and oil quality; install vibration isolation if needed.
Usage Notes Regularly replace hydraulic oil and filter; inspect flyweight and hydraulic valve for wear and oil leakage.
