Description
The
apparatus consists of a pad, which can be tilted to the required angle. An
endless belt, which moves beneath the pad, carries the oil over its surface
from oil bath. When the pad is tilted over the oil film, pressure is
developed, the pad is provided with pressure tapings parallel and
perpendicular to belt direction. The pressure distribution is measured over a
multi tube manometer. The belt is driven by a variable speed motor. The
tilting angle and minimum gap between pad and belt can be adjusted and
characteristics thus can be studied at various gaps, inclination and relative
surface speeds.
SCOPE OF EXPERIMENTATIONS:
Demonstration of pressure development.
Plotting pressure variation curve in longitudinal & transverse
direction of a pad for various speeds and pad inclination.
Demonstration of cavitations phenomenon.
UTILITIES REQUIRED:
Power Supply 230 V AC, Single
