ROTARY TORQUE GAUGE, IDLER
& RECORDING SYSTEMS
|
The Atlas Rotary Torque is
designed to give an indication of various down hold
conditions, thus warning the driller of locked cones,
dull bit, stress on the drill pipe, etc. As a result,
the danger of twist-off is reduced. During directional
drilling applications, the driller can reduce the
effects of hold friction due to coring, milling, or
washing over, by observing constant torque, rather than
constant weight. |

The Atlas Rotary Torque
Gauge should be set to zero while the drill stem is
rotated at normal operation speeds off bottom. As weight
is applied to the bit, the resultant increase is the
actual measurement of drilling torque. The sensing unit
(idler assembly) is installed under the bottom side of
the rotary chain. This assembly acts as a lever. As
torque is built up, the rotary chain becomes tighter and
presses down upon the wheel turning the idler frame. As
a result, there is an increase in hydraulic pressure
within the cylinder. This pressure signal is carried
from the cylinder through high pressure host to the dial
indicating gauge mounted in front of the driller.
The Atlas Idler Assembly
consisting of frame, base with mounting pads, hard
rubber wheel, and cylinder with stainless steel piston
rod is designed to provide the maximum service life.
The solid hard rubber wheel
has been designed without molding seams (high pressure
induction process); thereby eliminating any fault areas
whereby the rotary chain could possibly rip the rubber
apart. The Atlas and Instrument Supply Co., Inc. is the
only oil field instrument manufacturer of this type of
seamless rotary torque wheel.
