On the other hand, I think the possibility exists that, if we take the help of spring to generate at least a part of control force, because the weight of governor mechanism which is added to sleeve and its primary function is to bring governor to lower most position or to effectively developed a control force, which takes the rotating

decreases, therefore it becomes necessary to increase the supply of working fluid. On the other hand, when the load on the engine decreases, its speed increases and thus less working fluid is required. The governor automatically controls the supply of working fluid to the engine with the varying load conditions and keeps

Module -7 Lecture – 2. We have already seen that, it is essential to have some control over input to an engine, to ensure that, it is run at the desirer operation speed when the maximum efficiency is achieved. We have also gone through quick classification of the different types of governor mechanism which used to be in
Speed Governor. We saw in a previous example that frequency deviation can be quite substantial -- more than. 3 Hz -- for 10% change in load. In fact this deviation is considered unacceptably large (at this frequency, the generators will trip due to over-speeding). Therefore, depending on the frequency dependence of load
what we achieve a mechanical system with the help of governors. So, this will be our topics of discussions governor and governor mechanism. In modern engineering, feed back controller of control is a very important subject by itself. However, in mechanical system it is very primitive concept of feed back control is achieved
Figure 1 Comparison of flywheel and governor. Types of governors: (i) Centrifugal type: It depends upon the ?. (ii) Inertia type: It depends upon the ? ?. = dt d. The centrifugal type is subdivided into. (i) Gravity loaded – the Watt, Porter and Proell governors. (ii) Spring loaded – the Hartnell, Wilson-Hartnell, Hurtung and
