Centrifugal governors are used in many modern repeating watches to limit the speed of the striking train, so the repeater does not run too quickly. Another kind of centrifugal governor consists of a pair of masses on a spindle inside a cylinder, the masses or the cylinder being coated with pads, somewhat like a centrifugal clutch or a drum brake.
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
The centrifugal governor is an early proportional control mechanism. A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops . It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for ...
Bahasa Indonesia; Íslenska; ... A centrifugal governor regulates the speed of an engine by using spinning masses that move radially, adjusting the throttle, as the ...
Centrifugal governor In most types, the linear movement of the piston is converted to a rotating movement via a connecting rod and a crankshaft or by a swashplate or other suitable mechanism. A flywheel is often used to ensure smooth rotation or to store energy to carry the engine through an un-powered part of the cycle.
A key requirement for the high-speed steam engine was accurate control of a constant speed, even under a rapidly changing load. Although the control of steam engines via a centrifugal governor dates back to Watt, this control was inadequate. These early governors operated a throttle valve to control the flow of steam to the engine. This gives ...
Earlier engines with Watt's centrifugal governor and throttle valve become inefficient when operating at low power. The Richardson governor [17] was used for stationary and portable engines produced by his employers, Robey & Co. [18] This is a simple link valve gear controlled automatically by a centrifugal governor. Rather than the Stephenson ...
The term 'cataract' became a synonym for dashpot, at least where this was associated with steam engines and their governors. They were used as a damping device to avoid over-sensitivity with centrifugal governors. [17] Cataracts were also used as an over-speed safety device for direct-acting water pumps.
