The set-up is designed
to study the working of different governors normally used to control the
speed. It consists of a main spindle, mounted vertically on the base plate.
This spindle is driven by a variable speed Motor which is also mounted
vertically on the same base plate. Any one governor assembly out of four can
be mounted on spindle. The spindle speed is controlled by speed control
unit. A graduated scale is fitted to the sleeve to measure the displacement.
SCOPE OF EXPERIMENTATIONS:
Determination of
characteristic curve of a sleeve position against speed of rotation for
all governors.
To study the effect
of varying the mass of the center sleeve in Porter and Proell Governor.
To study the effect
of varying the initial spring compression in Hartnell Governor.
To
study the determination of characteristics curves of radius of rotation
against controlling force (Actual & Theoretical) for all governors.
UTILITIES REQUIRED:
Power Supply
230 V AC, Single
Phase.
Floor Space
1.5 x 1.5 m
Tachometer
to find out RPM.
TECHNICAL DETAILS:
Spindle
Material Stainless Steel
Governor Mechanism
Four different types of governor mechanism with spring and weights.
