About This Product
A governor keeps the speed of an engine nearly steady by moving a sleeve when the speed changes, which adjusts the supply of fuel or steam. Watt, Porter, Proell and Hartnell governors do this in different ways, using weights and springs. On this unit students plot sleeve position against speed for each governor and compare the effect of changing the mass or spring compression. School Lab Equipment India supplies the Universal Governor Apparatus across India and can export it to Djibouti, Mauritania, United Arab Emirates, Kiribati and Kazakhstan.
Frequently Asked Questions
Q1. Which governors can be studied on the Universal Governor Apparatus?
Four governor mechanisms with spring and weights are listed: Watt, Porter, Hartnell and Proell. Any one can be mounted on the spindle at a time.
Q2. Which experiments can be done on it?
Students can determine the characteristic curve of sleeve position against speed for all governors, study the effect of the centre sleeve mass in the Porter and Proell governors and of the initial spring compression in the Hartnell governor, and plot radius of rotation against controlling force.
