THE SEMINAR BREAKS INTO FOUR TOPICS
COMMON FAILURES CAUSED BY LACK OF LUBRICATION
SELECTION OF ROCK DRILL OIL
THE WORKINGS OF THE LUBRICATOR
SOME HELPFUL OPERATING HINTS
THE PRESENTATION IS FOLLOWED BY A DISCUSSION OR QUESTION AND ANSWER PERIOD

11. How Does it Work
COMPRESSED AIR ENTERS THE LUBRICATOR AND TRAVELS INSIDE A TUBE THROUGH THE CENTER OF THE LUBRICATOR.
AS THE AIR STREAMS THROUGH THE TUBE SOME AIR ENTERS A PORT IN A NOZZLE ASSEMBLY THAT INTERSTECTS THE TUBE
AIR ENTERING THE PORT TRAVELS UP THE PORT IN THE NOZZLE TO A CHAMBER ABOVE THE SURFACE OF THE LUBRICANT IN THE RESERVOIR
THE CHAMBER FILLS WITH AIR AND FORCES DOWN ON THE SURFACE OF THE LUBRICANT IN THE RESERVOIR.
THE INCREASING PRESSURE IN THE CHAMBER FORCES LUBRICANT INTO A PORT IN THE BOTTOM OF THE NOZZLE ASSEMLBY
THE LUBRICANT RISES IN THIS PORT TO AN EXIT INSIDE THE TUBE WHERE THE COMPRESSED AIR IS STREAMING PAST
THE LUBRICANT SPRAYS OUT OF THE PORT AND SOON FORMS A CONTINUOUS STREAM OF MIST IN THE AIR FLOW.

12. Setting the Lubricator
FOOTBALL STYLE LUBRICATORS CAN BE SET TO DISBURSE TRIPLE ZERO ROCK DRILL GREASE AS WELL AS QUALITY ROCK DRILL OIL
BEFORE SETTING THE LUBRICATOR SHUT OFF THE AIR AND DRAIN OFF ANY REMAINING PRESSURE BY BLOWING THE AIR LINE
ALWAYS WIPE AWAY DIRT FROM AROUND THE CAP BEFORE OPENING THE LUBRICATOR
USE A WRENCH TO LOOSEN THE SAFETY FILLER CAP
IF THE SYSTEM IS STILL UNDER PRESSURE A SUDDEN HISS OF AIR WILL WARN YOU.
RE-TIGHTEN THE CAP, BE SURE THE AIR IS OFF AND RELEASE THE PRESSUE
PHQ LUBRICATORS ARE SET IN THE FULL FLOW POSITION FOR MAXIMUM LUBRICATION
TO CHANGE SETTINGS TURN THE NOZZLE WITH A SCREWDRIVER OR CLEAN HOSE CLAMP
TURN NOZZLE NINETY DEGREES TO THE AIR STREAM FOR MEDIUM FLOW SETTING
TURN NOZZLE FORTY FIVE DEGREES TO THE AIR STREAM FOR THE LOWEST FLOW SETTING
RETURN THE NOZZLE IN LINE WITH THE AIR STREAM FOR FULL FLOW SETTING.
REPLACE THE FILLER CAP AND TIGHTEN WITH A WRENCH BEFORE TURNING ON THE AIR.

13. Shut off the Air Before opening the lubricator
ALWAYS BE SURE TO SHUT OFF THE AIR SUPPLY AND BLEED THE PRESSURE BEFORE OPENING THE LUBRICATOR.
THE LUBRICATOR HAS A SAFETY FILLER CAP THAT WILL RELEASE A HISS OF AIR BEFORE THE CAP IS FULLY UNTHREADED TO WARN THAT THE VESSEL IS PRESSURIZED.
SIMPLY RETIGHTEN THE CAP AND SHUT OFF THE AIR TO BLEED THE PRESSURE.

14. Filling the Lubricator
FOOTBALL STYLE LUBRICATORS ARE DESIGINED FOR USE WITH PROPER ROCK DRILL OIL OR TRIPLE ZERO ROCK DRILL GREASE
BEFORE DOING ANYTHING WITH THE LUBRICATOR SHUT OFF THE AIR AND DRAIN OFF THE PRESSURE (BY RUNNING THE DRILL THROTTLE TO STOP)
ALWAYS WIPE AWAY DIRT FROM AROUND THE FILLER CAP BEFORE OPENING THE LUBRICATOR
USE A STANDARD MINE WRENCH TO LOOSEN THE CAP
A SUDDEN HISS OF AIR SIGNALS THE SYSTEM STILL HAS PRESSURE.
RE-TIGHTEN THE CAP, CHECK TO BE SURE THE AIR IS OFF AND RELEASE THE PRESSUE
FILL THE LUBRICATOR FROM A SUITABLE OIL BOTTLE OR CONTAINER
PHQ RECOMMENDS AND SELLS OIL SAFE CONTAINERS WITH SEALING LIDS DESIGNED TO KEEP OIL CLEAN
THE OIL SAFE PUMP MAKES IT EASY TO FILL THE LUBRICATOR WITH TRIPLE ZERO ROCK DRILL GREASE OR OIL
THE OIL SAFE POURING SPOUT CONTAINER IS A GOOD ALTERNATIVE FOR OIL AND TRIPLE ZERO GREASE
FILL THE LUBRICATOR UNTIL THE LEVEL OF THE LUBRICANT IS JUST BELOW THE TOP OF THE NOZZLE
REPLACE THE FILLER CAP AND TIGHTEN WITH A MINE WRENCH BEFORE TURNING ON THE AIR.

15. Blow the Air Line PART FAILURES
LACK OF LUBRICATION IN DRILLS ATTACKS MOST OF THE PARTS IN THE DRILL AND IMMEDIATELY DAMAGES THE MOVING PARTS.
A FEW PARTS WE WILL SHOW ARE JUST EXAMPLES OF THE TYPE OF PROBLEMS THAT WILL OCCUR.
THE SAME TYPE OF PROBLEMS WILL OCCUR TO OTHER MOVING PARTS IN THE DRILL.
THE PARTS DISCUSSED WILL BE:
PISTON AND DRILL CYLINDER
RIFLE BAR AND RIFLE NUT
FRONT END OF THE DRILL AND CHUCK DRIVER
WE DISCUSS ACCELERATED WEAR OF PARTS.

16. Location
LOCATION OF THE LUBRICATOR IN THE AIR LINE IS CRITICAL TO PROVIDING PROPER LUBRICATION TO EQUIPMENT
THE LUBRICATOR SHOULD BE AS CLOSE TO THE EQUIPMENT AS POSSIBLE.
THE OIL MISTED BY THE LUBRICATOR REMAINS IN SUSPENSION IN THE AIR FLOW FOR ONLY A SHORT DISTANCE
FOR JACKLEG AND STOPER DRILLS IT IS PRACTICAL TO LOCATE THE LUBRICATOR WITHIN TWELV E FEET OF THE DRILL
FOOTBALL TYPE LUBRICATORS ARE DESIGNED TO BE USED IN A HORIZONTAL POSTION
THE LUBRICATOR CAN BE USED IN A VERTICAL POSITION BUT WILL ALL THE OIL ABOVE THE NOZZLE FAIRLY QUICKLY
WHEN USING THE LUBRICATOR IN RAISE WORK IT IS BEST TO FASTEN IT IN A HORIZONTAL POSITION.

17. Location MAXIMUM 12 FEET FROM DRILL PART FAILURES
LACK OF LUBRICATION IN DRILLS ATTACKS MOST OF THE PARTS IN THE DRILL AND IMMEDIATELY DAMAGES THE MOVING PARTS.
A FEW PARTS WE WILL SHOW ARE JUST EXAMPLES OF THE TYPE OF PROBLEMS THAT WILL OCCUR.

OF to +80OF
OF to +80oF

22. Recycled Drill Oil
THE OIL USED TO LUBRICATE DRILLS IS MISTED IN THE LUBRICATOR AND BLOWN THROUGH THE DRILL TO LUBRICATE THE WORKING PARTS.
THE OIL HELD IN THE AIR IS EXHAUSTED FROM THE DRILL SO IT CANNOT BE RECOVERED TO RECYCLE

23. Lack of Lubrication Cut-away Front End Portion of Rifle Bar
LACK OF LUBRICATION IN THE DRILL CAUSES THE WEARING PARTS WHICH ARE RUBBING ON EACH OTHER TO HEAT UP AND TO SCORE THE GROUND SURFACES OF THE COMPONENTS. ONE CAN SEE THE EXTREME SCORING ON THE INSIDE OF THE DRILL’S FRONT END THAT HOUSES THE CHUCK.
THE HEAT GENERATED BY THE MOVING PARTS CAN REACH EXTREME TEMPERATURES HOT ENOUGH TO CAUSE THE STEEL IN THE PARTS TO CRACK. ONE CAN SEE THE CRACKS RUNNING ACROSS THE FLUES OF THE PORTION OF RIFLE BAR IN THE PICTURE ON THE RIGHT.
A DRILL WITHOUT LUBRICATION CAN “BURN” BADLY WITHIN ONLY A FEW MINUTES AND EXPERIENCE SEVERE DAMAGE TO THE MOVING PARTS AS WELL AS THE INSIDE WALLS OF THE CYLINDER AND FRONT END OF THE DRILL.
Rapid damaging wear from heat due to lack of lubrication

24. Lack of Lubrication Burnt and Scored Piston New Rifle Nut Vs Used
LACK OF LUBRICATION CAUSES THE CHECK MARKS EVIDENT ON THE OUTSIDE DIAMETER OF THE PISTON HEAD IN THIS PICTURE. ONE CAN ALSO SEE CRACKS CAUSED BY HIGH HEAT RUNNING ACROSS THE SPLINES OF THE PISTON.
THE HEAT ALSO CAUSES THE BRONZE PARTS TO INCREASE IN SIZE SQUEEZING DOWN THE TOLERANCES BETWEEN THE MOVING PARTS AND CAUSING MORE FRICTION.
THE WORN RIFLE NUT ON THE RIGHT HAS LOST A CONSIDERABLE AMOUNT OF MATERIAL WHEN COMPARED TO THE NEW RIFLE NUT ON THE LEFT IN THE PICTURE ABOVE. HEAT GENERATED BY MOVING PARTS WITH LITTLE OR NO LUBRICATION WILL RAPIDLY ACCELERATE THE WEAR OF BRONZE PARTS SUCH AS THE RIFLE NUT.
Premature failure from heat caused by lack of lubrication

25. OIL Vs GREASE OIL PRODUCES A MIST OF OIL IN THE AIR AROUND THE DRILL
GREASE DOES NOT PRODUCE A MIST IN THE AIR AROUND THE DRILL
ALL MINE AIR SUPPLY CARRIES WATER SUSPENDED IN THE AIR.
WATER CONDENSES AS THE AIR ENTERS THE COLD UNDERGROUND

32. TIPS Always blow the air hose before connecting.
Pour some lubricant into the hose at the drill
Store drills in an upright position out of water
Connect air and water hoses together in storage
Stuff a rag in the chuck to keep dirt out
Check to be sure drill steel collars are clean
Use one lubricator for each drill
THE FOOT BALL TYPE LUBRICATOR REQUIRES VERY LITTLE MAINTENANCE.
THE MECHANISM INSIDE THE LUBRICATOR IS VERY SIMPLE.
THE ONLY PROBLEM THAT IS EXPERIENCED IS PLUGGING OF THE SMALL AIR PORTS IN THE REGULATING PIN.
OCCASIONALLY THE OIL CHAMBER IN THE LUBRICATOR MAY BE FLUSHED WITH SOLVENT TO REMOVE ANY SLUDGE THAT MIGHT HAVE BUILT UP.
THE SMALL AIR PORTS IN THE REGULATING PIN CAN USUALLY BE CLEANED WITH FINE STIFF WIRE.
