Description
Woodward TG-17ED8516-053
Technical Specifications
- Model: TG-17ED.
- Part Number: 8516-053.
- Control Type: Electro-hydraulic with self-contained oil.
Functional Features
- Custom Calibration: Factory-configured to match the exact hydraulic and mechanical parameters of the target steam turbine.
- Digital Integration: Optimized for use with Woodward MicroNet, 505, or similar digital control platforms.
- Enhanced Diagnostics: Provides electronic feedback on actuator position and system health.
Application Scenarios
Deployed in turbine modernization projects where upgrading to digital control requires a direct mechanical replacement for legacy TG-17 or PG series governors.
Performance Parameters
- Positioning Accuracy: High-resolution electronic feedback ensures precise valve positioning.
- Dynamic Response: Fast-acting servo valve for rapid load acceptance and rejection.
Material Composition
Industrial-grade electro-hydraulic components, robust housing, and high-integrity seals for leak-free operation.
Structural Characteristics
- Direct Retrofit: Mechanical mounting and linkage interface matches the 8516-053 specification.
- Integrated Electronics: Position transducer and servo amplifier housed within the actuator assembly.
Working Principle
The digital controller calculates the required valve position and sends a command to the TG-17ED. The internal servo valve directs self-contained hydraulic oil to move the piston to the exact position, continuously verifying the position via the internal feedback transducer.
Installation Requirements
Follow the specific wiring diagram for the 8516-053 configuration. Ensure mechanical linkage is correctly adjusted to match the actuator’s stroke limits.
Precautions for Use
Never apply power before verifying all mechanical connections and linkage clearances. Perform a full stroke calibration via the digital controller after installation.
