DRAWWORKS BRAKE
The “Drill Master Brake” is an excellent Energy Absorber for
Winch, Tensioning & Drilling applications requiring high
torque, low speed and especially for precise “WOB” control.
The oil shear system is very smooth eliminating stick slip and
chatter common to low speed drum rotation in hard rock
formations. Also by using the fluid for lubrication and cooling
the like under load is extremely long; allowing for continuous
drilling for weeks or months with no change in characteristics.
The quick response piston and low inertia is also beneficial in
drilling under varying load conditions such as rock to sand to
shale, without interruption of drilling operations.
FEATURES AND BENEFITS
Smooth Consistent Control – Precise “WOB” (see chart below)
• State of the Art friction materials and fluids have been
developed for very smooth and consistent operation; jerks, steps,
chatter, etc. have been virtually eliminated.
• Controlled fluid temperature through the brake improves
consistency for precision drilling.
Stable Torque Control
• Smooth, consistent actuation with low piston hysteresis is
experienced by using Teflon Liners over the O-Rings to seal the
non-rotating piston. This eliminates stick slip often associated
with O-Rings seals.
• Torque is controlled by actuation pressure and is
independent of speeds above the residual (minimum) drag
torque.
Low Speed Capability
• Operational speeds at levels down to 0 RPM “Dynamic”
are precisely controlled without chatter, stick slip or torque
variation, a overall tolerance of +/- .001 full range torque is
common practice.
• Speed-up drives which can influence drill results are
eliminated.
High Torque and Horsepower Capability
• Various sizes available from 500 – 5000 HP and is
capable of continuous heat absorption due to thermal
horsepower during tripping or high casing loads.
Quiet Operation
• Extremely quiet operation with noise levels of the brake
system below 65 db.
Quick Response for Computer Control – Auto Driller
• Quick, precise piston actuation produces excellent
response to manually or computer generated signals, 200 ms
total cycle time.
• Low rotating mass inertia for increased responsiveness to
changes in torque requirements.
No Adjustment Required
• Adjustment is not required making it very useful for long
continuous drilling of many months duration without shutting
down for brake adjustments or repairs.
Long Service Life
• Oil shear technology nearly eliminates the frictional wear
of the disc stack. Therefore long life and low maintenance
costs are experienced inexpensive repair kits are available from
stock. Repairs can be made on the drill floor.
• An external wear indicator indicates the need for
impending stack replacement long before actual failure would
occur.
Totally Enclosed Design
• The totally enclosed design eliminates any
contamination from salt air or fluids at the drill floor with friction
materials or other harmful contaminates.
