UG-40 Governor

UG-40 Dial and Lever Governors

The UG-40 governor is a mechanical-hydraulic speed governor for controlling diesel, dual fuel, or gas engines and steam turbines driving alternators, dc generators, pumps, compressors, or marine propellers

The maximum work output of the UG-40 is 50 ft-lb (67 J) when using the full 38- degree travel of the terminal shaft. Useful work capacity is 2/3 or 33 ft-lb (45 J) using 25 degrees of terminal-shaft travel. The useful travel of the output shaft is limited by the need to allow sufficient overtravel at each end so the governor can create a shutdown and also give maximum fuel when required. The terminal shaft Is mechanically linked to the fuel system

A proportional governor, the UG-40 Dial has an externally adjustable speed droop (knob) with 0 to 14% at 1000 rpm and 38 degrees terminal-shaft travel. The governor provides 0 to 17% droop at 800 rpm and 38 degrees of terminalshaft travel. A reduction in the amount of terminal-shaft travel used causes a corresponding reduction in the amount of droop available.

 

Droop is available for the Lever governor. Lever governor droop is internally adjustable at 0 to 7.5% at 1000 rpm and 0 to 9.5% at 800 rpm. Both figures assume 38 degrees of terminal shaft travel,

A load-limit control Is a standard feature on the UG-40 Dial governor. It limits the amount of fuel supplied by restricting the travel of the governor output shaft. An indicator dial shows the setting of governor-output-shaft limit position. The loadlimit control may also be used for shutting down the engine, turbine, or other type of prime mover by turning it to zero. Load limit is available on the lever governor as a factory option.
