Woodward 9904-114

Woodward 9904-114

Woodward’s TGE governors are highly regarded for their durability and reliable performance, even in demanding industrial environments. The 9904-114 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 4000 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.
  • 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 4000 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 “-114” suffix identifying its particular specifications, in this case, a TGE17 governor optimized for 4000 RPM.

WOODWARD 9904-114: TGE17 Governor (4000 RPM)

 

The Woodward 9904-114 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: 4000 RPM

 

Detailed Description

 

Woodward’s TGE governors are highly regarded for their durability and reliable performance, even in demanding industrial environments. The 9904-114 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 4000 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.

The “9904” series from Woodward often categorizes specific governor models or configurations, with the “-114” suffix identifying its particular specifications, in this case, a TGE17 governor optimized for 4000 RPM.

 

Applications

 

The Woodward 9904-114 (TGE17, 4000 RPM) would typically be employed in applications such as:

  • Power Generation: Controlling the speed of steam turbines or gas turbines connected to generators for stable electricity production.
  • Industrial Compressors and Pumps: Regulating the speed of prime movers driving these critical pieces of equipment in oil & gas, chemical, or manufacturing industries.
  • Other High-Speed Industrial Machinery: Providing precise speed governing for various equipment requiring consistent operation at 4000 RPM.

Its 4000 RPM rating makes it suitable for many common industrial prime movers that operate within this speed range.

 

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 (Previously identified as 2400 RPM, but based on search results for 9904-114 and common patterns, it is indeed 4000 RPM)
  • 9904-114: TGE17 Governor, 4000 RPM (This part, confirming its TGE17 and 4000 RPM rating)
  • 9904-115: TGE17 Governor, 6000 RPM (Expected based on pattern, but the direct search results for 9904-114 indicate it’s 4000 RPM. It’s possible there are variations or mislabeling in some online sources. It’s important to cross-reference with official Woodward documentation where possible.)

This pattern illustrates how different TGE governor models (13 or 17) are offered with specific speed ratings under this numbering scheme, providing tailored solutions for diverse prime mover requirements.
