Description
Woodward TG-13(8516-038)
Technical Specifications
- Model: TG-13.
- Specific Configuration: 8516-038.
- Control Type: Self-contained droop governor.
Functional Features
- Application Specific: Calibrated for the exact steam flow and load dynamics of the designated turbine.
- Autonomous Operation: Requires no external electrical power or control oil.
- Stable Regulation: Ensures smooth speed transitions during load changes.
Application Scenarios
Deployed in industrial steam systems where precise, non-synchronous speed control is required for mechanical drives or auxiliary power.
Performance Parameters
- Output Shaft Limit: 40° maximum angular displacement.
- Operational Envelope: Center 2/3 of stroke utilized for active control.
Material Composition
Heavy-duty industrial metals and precision seals designed for decades of continuous steam turbine service.
Structural Characteristics
- Self-Contained: Internal oil sump eliminates external oil lines.
- Mechanical Linkage Interface: Direct shaft output for valve actuation.
Working Principle
Mechanical flyweights sense turbine speed and modulate an internal hydraulic pilot valve. The resulting oil pressure drives a servo piston that adjusts the steam valve, maintaining the desired droop speed characteristic.
Installation Requirements
Ensure proper alignment between the governor output shaft and the turbine steam valve. Verify oil level before initial startup.
Precautions for Use
Maintain strict oil cleanliness standards. Periodically verify the mechanical linkage for free movement and absence of excessive wear.
