WOODWARD 9904-111

WOODWARD 9904-111

Woodward’s TGE governors are renowned for their robustness and reliable performance in demanding industrial environments. The 9904-111 likely indicates a standard configuration of the TGE13 governor that is specifically designed or factory-set for applications where the controlled prime mover operates at a nominal speed of 6000 RPM.

Key characteristics of TGE13 governors generally include:

  • Precise Speed Control: They offer highly accurate control over the prime mover’s speed, which is crucial for maintaining stable electrical frequency in power generation or consistent performance in mechanical drive applications.
  • Mechanical-Hydraulic Operation: These governors utilize a combination of mechanical principles (such as flyweights for sensing speed changes) and hydraulic principles (using oil pressure to move an actuator) to achieve effective control.
  • Built for Durability: Designed for extended service life and consistent, reliable performance even in harsh industrial settings.
  • Versatile Applications: While the 9904-111 is tailored for a 6000 RPM rating, 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 “-111” suffix identifying its particular specifications, in this case, a TGE13 governor optimized for 6000 RPM.

The “9904” series from Woodward often categorizes specific governor models or configurations, with the “-111” suffix identifying its particular specifications, in this case, a TGE13 governor optimized for 6000 RPM.

 

Applications

 

The Woodward 9904-111 (TGE13, 6000 RPM) would typically be employed in applications that require very high-speed control, such as:

  • High-Speed Industrial Gas Turbines: Controlling fuel delivery to maintain precise turbine speed for specialized power generation, high-speed compression, or pumping.
  • High-Speed Steam Turbines: Regulating steam admission for turbines in power plants or industrial processes where high rotational speeds are critical.
  • Specialized Test Stands: Providing accurate speed governing for engines or turbines used in research, development, or performance testing.

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

 

Related Products/Series

 

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

  • 9904-110: TGE13 Governor, 4000 RPM
  • 9904-111: TGE13 Governor, 6000 RPM (This part)
  • 9904-112: TGE17 Governor, 2400 RPM
  • 9904-113: TGE17 Governor, 4000 RPM
  • 9904-114: TGE17 Governor, 6000 RPM

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.
