Which is more sensitive governor?
Porter governor is more sensitive than watt governor. The proell governor is most sensitive out of these three. This governor was used by James Watt in his steam engine. The spindle is driven by the output shaft of the prime mover.
What is the function of a governor *?
The primary function of the governor is to preserve, protect and defend the constitution and the law as incorporated in their oath of office under Article 159 of the Indian constitution in the administration of the State affairs.
What are the types of governor?
Types of Governors
- Mechanical or centrifugal governor.
- Pneumatic governor.
- Hydraulic governor.
Which governor cant be used for high speed?
Explanation: The isochronous governor is not of practical use because the sleeve will move to one of its extreme positions immediately the speed deviates from the isochronous speed.
What is range of governor?
It is observed from the example taken that the speed range for watt governor was from 66.89 rpm to 77.24 rpm. And in modified watt governor by taking c=10 range was 77.72 rpm to 90.01 rpm. Over all we can say that working range is increased.
What are the two major types of governor?
The Governors are mainly divided into two types i.e Centrifugal Governor and Inertia Governor. These are further divided into following types according to their design.
Why is hunting a property of a governor?
Hunting is not a desirable property of a governor.As we know.governor works when a change in load is applied to engine..But if the governor is very sensitive i.e.it works even in a small change in load,that is keeps moving up and down about its mean position,Then this is known as hunting.
Which is true about the stability of Governor?
Stability of governor. For every speed within governor speed range there is specific equilibrium configuration (radius of ball rotation, sleeve lift) and there is no much hunting, then the governor said to be stable.
Which is a result of too sensitiveness of Governor?
Hunting is a result of too sensitiveness of governor. It causes continuous fluctuation in engine speed, above and below the mean speed. This phenomenon is known as hunting. The high sensitiveness of governor results in substantial change in fuel supply for small change in engine speed.
Can a Porter governor be an isochronous governor?
If the range of equilibrium speed is zero (equilibrium speed is constant) for all radius of rotation of ball, the governor is said Isochronous governor. It is a stage of infinite sensitivity. Porter governor cannot be isochronous. Stability and sensitiveness are two opposite characteristics.
