Which among the following is not spring controlled governor? 

Which among the following is not spring controlled governor?  Correct Answer Proell governor 

Explanation:

Governor: It is a device used for maintaining a constant mean speed of rotation of the crankshaft over long periods during which the load of the engine may vary. Governor maintains constant speed by controlling the supply of working fluid as the load varies.

Governors are classified as:

  • Centrifugal Governor
  • Inertia Governor

Centrifugal Governors are classified as:

  • Dead Weight Governors:
    • Porter governor
    • Proell governor
  • Spring controlled governors:
    • Hartnell governor
    • Hartung governor
    • Pickering governor

Hence except proell governor all other options are spring controlled governor.

A Pickering governor is driving a gramophone. Each disc attached to the centre of a leaf spring has a mass of 20 g. The width of each spring is 5 mm and thickness of 0.125 mm. The effective length of each spring is 40 mm. The distance from the spindle axis to the centre of gravity of the mass when the governor is at rest, is 10 mm. Find the speed of the governor in rpm when the sleeve has risen to a height of 0.8 mm. (E = 210kN/mm2)
