🔍 Key Concepts

• Operation of a centrifugal (flyweight) governor when shaft speed increases • How movement of the governor sleeve/lever changes the position of the pilot valve in a hydraulic governor • Direction of oil flow to or from the operating cylinder when the governor is trying to reduce steam to the turbine

💭 Think About

• When the turbine speeds up, do the governor weights move inward or outward under centrifugal force? Visualize what that does to the sleeve and linked parts in the illustration. • Trace the motion from the flyweights to the lifting beam and then to the pilot valve: as the sleeve moves, does the pilot valve go up or down relative to its ports? • If the governor senses overspeed, is it trying to open the steam valves further or close them slightly? How would that goal affect whether oil is admitted to or drained from the operating cylinder?

✅ Before You Answer

• Look closely at the linkages between the weights, sleeve, lifting beam, and pilot valve in SE-0009 and determine which direction each moves for an increase in speed. • Confirm which movement of the pilot valve (up or down) causes pressure oil to enter the operating cylinder versus allowing oil to return to the sump. • Make sure your chosen option matches a sequence that would tend to reduce steam flow to correct an overspeed condition.
