Study of Watt Governor Mechanism

Abstract

Objective:The basic aim of the study is to determine the minimum, maximum speeds and sensitivity of the governor of a universal Watt governor setup available in machine dynamics laboratory in the mechanical engineering department at Jamia Millia Islamia New Delhi. Methodology: We used a tachometer to measure the spindle speed in revolution per minute. After assembling the governor setup, the author note down the initial reading of pointer on the vertical scale. After switching on the rotary switch, we slowly increase the governor speed till the sleeve is lifted from its initial position and it should be stabilized. Now, again, we increase the governor speeds in steps to get different position of sleeve lift at different rpm and noted all the observations. Findings: The actual minimum and maximum governor speeds are 211 rpm and 276 rpm respectively. The actual sensitivity of the available governor setup is 26.7 %. With the change of governor speed, the radius of rotation also changes. Novelty: This Study may be sued as simple guide lines for undergraduate / postgraduate / research scholars as well as scientist to select the suitable governor to perform the required task as per specific necessity in their research work.
