Woodward 9904-115

Woodward 9904-115

Woodward’s TGE governors are highly regarded for their durability and reliable performance, even in demanding industrial environments. The 9904-115 indicates a standard configuration of the TGE17 governor that’s specifically designed or factory-set for applications where the controlled prime mover operates at a nominal speed of 6000 RPM.

Key characteristics of TGE17 governors typically include:

  • Precise Speed Control: They offer highly accurate control over the prime mover’s speed, which is vital for maintaining consistent electrical frequency in power generation or stable performance in mechanical drive systems.
  • Mechanical-Hydraulic Operation: These governors use a combination of mechanical principles (like flyweights for sensing speed variations) and hydraulic principles (using oil pressure to actuate control mechanisms) to achieve effective and responsive speed control.
  • Higher Work Output: Compared to the TG-13 models, the TGE17 typically provides a higher work output (e.g., 23.7 N·m or 17.5 lb-ft), making it suitable for larger control valves or linkages that require more force.
  • Built for Durability: Designed for long service life and consistent, reliable performance in challenging industrial settings.
  • Versatile Applications: While this specific configuration is tailored for 6000 RPM, TGE governors are broadly adaptable across various types of prime movers.

The “9904” series from Woodward often categorizes specific governor models or configurations, with the “-115” suffix identifying its particular specifications, in this case, a TGE17 governor optimized for 6000 RPM.

WOODWARD 9904-115: TGE17 Governor (6000 RPM)

 

The Woodward 9904-115 designates a specific version of a TGE17 mechanical-hydraulic governor. These governors are essential devices that precisely control the speed of prime movers such as industrial gas turbines, steam turbines, or large diesel engines. They work by regulating the flow of fuel or steam to maintain a desired operating speed and power output, ensuring stable and efficient performance.

 

Product Overview

 

  • Product Type: Mechanical-Hydraulic Governor
  • Manufacturer: Woodward
  • Governor Type: TGE17 (a model within the TG series, known for a higher work output compared to the TG-13)
  • Rated Speed: 6000 RPM

Applications

 

The Woodward 9904-115 (TGE17, 6000 RPM) would typically be employed in applications such as:

  • High-Speed Power Generation: Controlling the speed of steam turbines or gas turbines connected to generators for stable electricity production, particularly where high rotational speeds are involved.
  • Specialized Industrial Compressors and Pumps: Regulating the speed of prime movers driving these critical pieces of equipment in oil & gas, chemical, or manufacturing industries that operate at very high speeds.
  • Other High-Speed Industrial Machinery: Providing precise speed governing for various high-performance equipment requiring consistent operation at 6000 RPM.

Its 6000 RPM rating makes it suitable for specific high-speed industrial prime movers.

 

Related Products/Series

 

The 9904-XXX series from Woodward typically covers various configurations of TGE13 and TGE17 governors, distinguished by their rated speeds:

  • 9904-110: TGE13 Governor, 4000 RPM
  • 9904-111: TGE13 Governor, 6000 RPM
  • 9904-112: TGE17 Governor, 2400 RPM
  • 9904-113: TGE17 Governor, 4000 RPM
  • 9904-114: TGE17 Governor, 4000 RPM (Note: While some sources might list this as 4000 RPM, based on the logical progression, it could also be a variant or a specific configuration. The 9904-115 confirms the TGE17 line extends to 6000 RPM.)
  • 9904-115: TGE17 Governor, 6000 RPM (This part, consistent with the highest speed for the TGE17 model in this series.)
