Description
Woodward 1766-523
Technical Specifications
- Brand: Woodward
- Part Number: 1766-523
- Product Type: Hydraulic Servo Motor
- Series: SMM40
Functional Features
- Precision Actuation: Provides highly accurate and responsive linear or rotary mechanical movement.
- Hydraulic Power: Utilizes pressurized hydraulic fluid to generate significant force for moving heavy fuel linkages.
- Closed-Loop Compatibility: Designed to work seamlessly with electronic governors and position feedback sensors.
Application Scenarios
Widely deployed in marine propulsion engines, large industrial diesel engines, and steam turbine fuel control systems.
Performance Parameters
- Dynamic Response: Fast actuation speed to accommodate rapid load changes or emergency shutdowns.
- Positioning Accuracy: Minimal deadband and high repeatability for stable engine speed control.
Material Composition
Constructed with heavy-duty cast iron or steel housing, precision-machined internal spools, and high-performance hydraulic seals.
Structural Characteristics
Features a robust cylindrical or rectangular profile with high-pressure hydraulic ports, mechanical output linkages, and integrated position feedback mounting points.
Working Principle
Receives a command signal from the engine controller, which directs a servo valve to route pressurized oil into the motor’s cylinder. The resulting hydraulic pressure drives the piston or vane to the exact commanded position.
Installation Requirements
Must be mechanically linked to the engine’s fuel rack or valve with precise alignment to prevent binding. Hydraulic supply and return lines must be properly routed and filtered.
Usage Precautions
Ensure hydraulic fluid cleanliness meets Woodward’s strict specifications. Never exceed the rated hydraulic supply pressure. Bleed air from the system before commissioning.
