  1. CENTRIFUGAL GOVERNOR Presented by: Rohan Lyall Objective: -To explain what a centrifugal governor is -To explain how it works -To present its applications and benefits

  2. What is a Centrifugal Governor? -The first governor was designed by James Watt in 1788 - A Governor is a feedback device on a machine or engine that is used to provide automatic control, as of speed, pressure, or temperature - A Centrifugal Governor (also known as Watt or fly-ball governor)is a specific type of governor, that controls the speed of an engine, by regulating the fuel admitted

  3. How Does it work? -Uses the principal of proportion control -A proportional control system - a type of linear feedback control system. -output signal of a system is passed back to the input -Two rotating masses that indirectly control the speed of the engine -These rotating masses are based on centrifugal force - As engine speed increases, Centrifugal force increases on masses which causes an upward lift. -The rotating masses are attached to valves that control the fuel flow into cylinders, which then controls the speed of the engine.

  5. APPLICATIONS OF THE CENTRIFUGAL GOVERNOR - Governors are used frequently in a variety of machine applications. - They are seen on steam engines, internal combustion engines and variously fueled turbines - They are used in: - Automobiles to restrict/maintain engine RPM, total speed - Governors protect engine from excessive rotational speed - used in some high performance cars to limit vehicle speed - Used in a spring-loaded record player, and telephone dials to limit the speed. l
