Description
Woodward TG-17A8516-045
Technical Specifications
- Base Model: TG-17A.
- Part Number: 8516-045.
- System: Self-contained mechanical-hydraulic.
Functional Features
- Customized Droop: Tailored speed droop characteristics for specific turbine load profiles.
- Independent Oil Supply: Internal reservoir ensures consistent hydraulic pressure regardless of external conditions.
- Rugged Reliability: Purely mechanical operation guarantees functionality in critical industrial environments.
Application Scenarios
Applied in small steam turbine drives for compressors, pumps, and industrial processes requiring stable, non-synchronous speed regulation.
Performance Parameters
- Max Shaft Rotation: 40 degrees.
- Effective Stroke: 2/3 of full travel recommended for no-load to full-load operation.
Material Composition
Precision-cast housings, hardened steel internal components, and high-temperature resistant seals.
Structural Characteristics
- Compact Footprint: Integrates all sensing, amplification, and oil storage into one unit.
- Direct Drive Output: Mechanical shaft for direct connection to turbine throttle mechanisms.
Working Principle
Rotational speed changes alter the centrifugal force on internal flyweights. This mechanical displacement shifts a hydraulic valve, directing oil to a power piston that repositions the turbine’s steam control valve to correct the speed deviation.
Installation Requirements
Mount securely to prevent vibration. Ensure the mechanical linkage to the steam valve is properly aligned and freely articulated.
Precautions for Use
Adhere to the specified oil type and change intervals. Never force the mechanical linkage if binding is detected; investigate and resolve the mechanical interference first.
