In the demanding world of maritime operations, reliable engine control systems are critical for safe and efficient vessel operations. The Woodward PG-EG governor stands as a premium solution for auxiliary engines, combining proven mechanical reliability with modern electronic precision to meet the rigorous demands of marine environments.
What is the Woodward PG-EG Governor/actuator?
The Woodward PG-EG 8577-1136 is a sophisticated governor/actuator system specifically engineered for marine applications requiring electronic engine control with mechanical backup capabilities. This innovative design merges the dependability of hydro-mechanical PG governors with the flexibility and precision of electronic control systems. (ref)
Unlike standard governors, the Woodward PG-EG governor features dual control mechanisms - electronic and mechanical - ensuring continuous operation even if one system fails. This redundancy is crucial for auxiliary engines that power essential ship machinery parts including lighting, navigation equipment, pumps, and safety systems.
Key Features and Benefits
Dual Control System The PG-EG governor operates with both electronic and mechanical control systems simultaneously. The mechanical governor provides pneumatic tracking of speed settings, enabling complete backup speed control from remote locations with minimal speed variation during electronic signal failures.
Wide Output Range With torque outputs ranging from 16 to 678 Nm (12 to 500 lb-ft), this governor accommodates all sizes of marine engines, making it versatile for various vessel types and applications.
Electronic Compatibility The actuator portion requires a 0-200 mA control signal, making it compatible with all Woodward electronic controls. This standardization simplifies integration with existing marine control systems.
Vibration-Resistant Construction Built specifically for marine environments, the governor features robust, vibration-resistant construction designed to meet SOLAS (Safety of Life at Sea) requirements, ensuring reliable operation in harsh sea conditions.
Applications in Marine Auxiliary Engines
Auxiliary engines serve as the electrical backbone of modern vessels, providing power for essential systems when main engines are offline or during emergency situations. The Woodward PG-EG governor ensures these critical power sources maintain stable operation under varying load conditions.
Power Generation Control For alternating current power generation, the governor maintains precise speed control within ±0.5% tolerance required for parallel operation of multiple generators. This precision prevents power quality issues that could damage sensitive ship machinery parts.
