Description
Woodward TYPEUG-8
Technical Specifications
- Type: Mechanical-hydraulic governor
- Application: Medium to large diesel engines
- Control Mode: Isochronous or droop speed control
Functional Features
- High-Force Output: Hydraulic servo provides sufficient force to move large fuel racks.
- Stable Regulation: Inherent damping characteristics prevent hunting and oscillation.
- Versatile Control: Configurable for isochronous or droop operation.
Application Scenarios
Deployed in large diesel generator sets, marine propulsion engines, and industrial mechanical drives.
Performance Parameters
- Speed Regulation: Stable isochronous or droop control.
- Actuator Force: High hydraulic output force for large fuel systems.
Material Composition
Heavy-duty metallurgy for internal hydraulic passages, precision-ground shafts, and high-temperature resistant seals.
Structural Characteristics
- Integrated Servo: Built-in hydraulic servo piston for direct fuel rack actuation.
- Adjustment Knobs: External speed setting and droop adjustment mechanisms.
Working Principle
Flyweights respond to speed changes and modulate a pilot valve. Hydraulic oil is directed to a servo piston that moves the fuel rack, maintaining the set speed with stable control characteristics.
Installation Requirements
Ensure rigid mounting and proper linkage alignment. Verify hydraulic oil supply and return lines are correctly connected.
Precautions for Use
Maintain strict oil cleanliness standards. Periodically verify linkage free travel and adjust as necessary to prevent binding.
