A large change in ambient temperature or using an oil of a viscosity different than the one recommended by the manufacturer in a mechanical hydraulic governor, will result in the need to adjust the __________.
• Mechanical hydraulic governor internal parts and their functions • How oil viscosity and temperature affect oil flow in small passages • Which governor components control rate of oil flow vs. position or force
• Think about which component’s job is most directly affected if the oil becomes much thicker or thinner than normal. • Ask yourself: which part is meant to be fine‑tuned when the flow characteristics of the oil change, rather than when the set speed or speed droop need adjustment? • Consider which choice is normally adjusted only when you want to change the dynamic response or damping of the governor, not its basic spring forces.
• Identify which option relates to flow restriction/damping rather than force or position alone. • Separate components that change the set speed or speed sensitivity from those that change how fast oil can move. • Verify which part is specifically intended to compensate for changes in oil flow due to temperature/viscosity, according to typical mechanical‑hydraulic governor design.
