Use, maintenance and common fault handling of the air drill
Use, maintenance and common fault handling of the air drill
Use of (I) Air Drill
(1) The air drill is filled with anti-rust oil when leaving the factory, which should be disassembled and washed before use, and the matching surface should be reassembled.Apply lubricating oil and drive the trolley for test run.
(2) When connecting the air pipe, the sundries in the pipe must be blown clean to avoid entering the body and affecting the normal operation of the machine;During rock drilling, the water pressure should be kept 0.1~0.15MPa lower than the air pressure to prevent flushing water from entering the body and affecting the lubrication.slippery, and bring in impurities.
(3) Before ventilation and water supply, carefully check whether each connection part is safe and reliable to avoid loosening and hurting people.
(4) Fill the lubricator with oil before drilling, and no lubrication operation is allowed.
(5) Adjust the oil valve and add oil once for each shift.
(6) When drilling, the pneumatic drill control valve should be opened to the light operation position, and the eye position should be firmly drilled for 20~30mm.After that, pull the pneumatic drill operator handle to the operating position to drill until the drill bit is not easy to leave the eye opening.Drill in.
(7) When working, pay special attention to prevent the drill from breaking suddenly; pay attention to prevent the operator fromWas pinched between his leg and gas.
(8) At the end of drilling, the water source should be turned off first, and then run lightly for a while to eliminate the accumulated water in the machine and preventRusty.
(9) The continuous use of pneumatic drill should be regularly maintained, remove the internal organs of the machine, replace the damaged parts, and remove the damaged parts.108 hidden dangers.
(10) If the used air drill is stored for a long time, it must be removed, washed, oiled and placed in a cool and dry place.
(II) maintenance and common fault handling
1. Routine maintenance
(1) Before repairing the air drill, water gun and cleaning agent should be used to thoroughly clean the dust and dry it.
(2) When the shaft pin in the machine head needs to be removed, pay special attention not to damage or destroy the matching of the machine head and the pin shaftsurface. When disassembling or assembling the pin shaft, do not rotate or operate the control handle, otherwise the pin shaft will pass through several grooves.Damage to the O-ring in the groove. Pay attention to the pin shaft thoroughly cleaned and buttered, and pat it in a straight line.
(3) When repairing the air leg, it should be fixed in a soft jacket, and it is not possible to use a vise, pipe wrench or chain.Fixed; Do not use solvent to clean the air leg; clean the air leg should use the specified cleaning agent and high-pressure water gun, which canWash alternately with hot water below 90 ℃ and detergent. Correct replacement of all sealing rings for air leg; incorrect useThe sealing ring will cause the air leg to run poorly.
2. Common fault handling
(1) The pneumatic drill cannot extend the air leg.
Reasons: ① the exhaust valve is blocked; ② the spring fracture causes the exhaust valve not to close; ③ the air leg is stuck.Elimination method: ① Remove the exhaust screw, check the exhaust hole and clean it; ② Remove the water valve and exhaust valve,Replace the spring; ③ Check the sealing condition of the slider, replace it if it is bad, and check whether the air leg is damaged.
(2) The air leg of the air drill does not land.
Reason: ① the air leg is fully extended, and the axis of the air leg cylinder is not in the center; ② the air leg is stuck; ③ the control air cannot reachExhaust valve; ④ Exhaust valve seal ring is damaged or spring is broken.
Elimination method: ① gently shake the air leg to fall freely; ② check the condition of the slider and replace it if necessary,Check the air leg; ③ Check each set of seat joints for air leakage; ④ Check and clean the water valve and exhaust valve, if necessaryReplacement.
(3) The air leg of the pneumatic drill cannot be lowered.
Reasons: ① low wind pressure; ② controller, filter blockage.
Elimination method: ① check the wind pressure; ② remove the cleaning, check the oil type.
(4) The advancing speed of the air drill is low or the extension of the air leg is slow.
Reasons: ① low wind pressure; ② air leg damage; ③ exhaust valve can not be closed; ④ exhaust valve closed slowly.
Elimination method: ① Check the wind pressure and filter screen; ② Check the damage of the air leg; ③ Remove the water valve and drainCheck the air valve and clean the exhaust valve.
