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, especially in high-performance environments, upgrading older governor models is often essential. The Woodward 8516-190 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. 6000 RPM Operation: Designed for very high-speed applications, this kit is compatible with governors operating at an impressive rated speed of 6000 RPM. This makes it suitable for specific high-speed turbines and industrial equipment.
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

Typical Applications

The Woodward 8516-190 conversion kit is primarily utilized in:

• High-Speed Power Generation Facilities: For modernizing governors on turbines or engines operating at very high speeds, ensuring continued safe operation and adherence to current standards.
• Specialized Industrial Processes: Where high-speed prime movers control critical equipment in potentially hazardous environments, requiring precise speed control and ATEX compliance.

Related Products

The 8516-190 kit is part of a comprehensive series of Woodward TG governor conversion kits. Other kits in this series, offering variations based on speed, rotation, and specific droop settings, include:

• Woodward TG-13 and TG-17 Governors: These are the older mechanical governors that are upgraded by these conversion kits.
• Woodward TG611-13 and TG611-17 Governors: These are the modernized versions that the kits help achieve.
• WOODWARD 8516-191: A similar conversion kit for the TG611-17, 6000 RPM, CCW rotation, ATEX, with OTD (and the same rated speed of 6050 RPM @ 2% Droop). This indicates that 8516-190 and 8516-191 form a pair for CW and CCW rotation at this specific very high RPM and droop setting.
• Other kits like 8516-174 through 8516-189 cater to different RPM ranges (2400 RPM, 3200 RPM, 4000 RPM) and include both TG611-13 and TG611-17 target models, with various combinations of CW/CCW rotation and droop settings.
