GOVERNOR

The governor is define as the when the load in engine increase its speed decrease then increase the supply of working fluid

and when the load on the engine decrease its speed increase and thus less working

fluid required is called by governor .

Types of governor

• There are two types of governor.• 1- centrifugal governor • 2- inertia governor

Centrifugal governor

• The centrifugal governor are based on the balancing of centrifugal force on the rotating balls by an equal and opposite radial force know as controlling force. It consist of two balls of a equal mass which are attached to the arms these balls known as governor ball or flywheel.

Centrifugal governor

In centrifugal watt governor

• The simplest form of a centrifugal governor it is watt governor. It is basically a conical pendulum with links attached to sleeve of negligible mass.

Watt governor

In centrifugal porter governor

• The porter governor is a modification of a watt governor which central load attached to the sleeve. The load moves up and down to the central spindle the additional downward force increase the speed of revolution to enable the balls to rise to any predetermined level.

Porter governor

Inertia governor

• This type a governor work on the principle of inertia of matter and is operated by acceleration and retardation of the rotating mass. The action of inertia governor is quicker then that of centrifugal type.

Inertia governor

Term used in governor

• 1- height of the governor – It Is the vertical distance from the centre of the balls to a point where the axis of the arms intersect of the spindle axis it is denoted by (h).

• 2- equilibrium speed – It is a speed at which the governor balls, arms are in complete equilibrium and the sleeve does not tend to move upward or downward.

• 3- Mean Equilibrium Speed – It is the speed at the mean position of the balls or the sleeve.

• 4- Maximum and minimum equilibrium speed – The speed at the maximum and minimum radius of rotation of the balls without tending to move either way known as maximum and minimum speed respectively.

• 5- Sleeve Lift – It is the vertical distance which the sleeve travels due to changes in equilibrium speed.
