Detailed Description

Woodward mechanical-hydraulic governors are critical for maintaining stable and safe operating speeds in turbine and other prime mover applications. To meet evolving industry standards and increasingly stringent safety regulations, upgrading older governor models is often essential. The Woodward 8516-186 kit offers a precise solution for this modernization.

This conversion kit transforms an existing TG governor into a more capable TG611-17 governor, integrating several critical features:

1. Overspeed Test Device (OTD): This essential safety mechanism allows for safe, routine testing of the governor’s overspeed protection function. Operators can verify that the overspeed trip system is fully functional without putting the prime mover at risk by actual overspeeding. This significantly enhances operational safety and system reliability.
2. ATEX Compliance: This certification is crucial for equipment operating in environments where explosive atmospheres may be present (e.g., in oil & gas facilities, chemical plants, or certain power generation sites). It confirms that the components meet stringent European Union directives for safety in hazardous locations.
3. Clockwise (CW) Rotation: The kit is precisely engineered for governors with a clockwise drive shaft rotation. This specification is critical for proper mechanical integration and operation with the specific design of the turbine or engine being controlled.
4. 2400 RPM Operation: This kit is compatible with governors operating at a rated speed of 2400 RPM, a common speed for various industrial turbines and engines.
5. Speed Droop Control: The TG611-17 governor operates using a speed droop control characteristic. This feature is fundamental for ensuring stable load sharing when multiple prime movers and generators are operating in parallel, and it plays a vital role in maintaining overall grid stability.

Technical Specifications

Applications

The Woodward 8516-186 conversion kit is primarily utilized in:

• Power Generation Facilities: For modernizing governors on turbines or engines operating at 2400 RPM, ensuring continued safe operation and adherence to current standards.
• Oil & Gas Installations: Where prime movers control critical equipment in potentially hazardous environments, requiring precise speed control and ATEX compliance.
• General Industrial Processes: For upgrading existing industrial prime movers to enhance their speed governing capabilities and safety features.

Difference between Woodward 8516-186 and 8516-185

The key difference between the Woodward 8516-186 and the 8516-185 lies in their drive shaft rotation direction:

• Woodward 8516-186: Is designed for Clockwise (CW) rotation.
• Woodward 8516-185: Is designed for Counter-Clockwise (CCW) rotation.

Both kits are otherwise very similar, targeting the TG611-17 conversion from TG-17 governors, operating at 2400 RPM, including the OTD and ATEX compliance, and having the same rated speed at 2% droop (2010 RPM). They essentially form a pair to accommodate different drive shaft rotation requirements.
