Solutions To Common Faults Of Air Leg Rock Drill And Gasoline Rock Drill
Air Leg Rock Drill And Gasoline Rock Drill uses compressed air to drive the piston to move back and forth. The piston strikes the drill tail during the stroke, and the piston drives the drill tool to rotate during the return stroke to break and drill the rock. It is an inevitable trend to replace the Air Leg Rock Drill And Gasoline Rock Drill with the full hydraulic drill truck in the development of coal mine rock roadway tunneling, but at present, more than 90% of the rock roadway tunneling construction is mainly air leg drilling.
1. Faults caused by low working air pressure of
Air Leg Rock Drill And Gasoline Rock Drill
The
Air Leg Rock Drill And Gasoline Rock Drill is used to calculate whether the air pressure pipeline is overloaded. If it is overloaded, the number of working machines can be reduced according to the actual situation, or other air consuming operations can be reduced. Eliminate the factors that cause pressure drop due to pipeline leakage, and check and replace the leakage pipeline and connector. The length of the gas transmission rubber pipe shall be controlled between 10m and 15m. Check and replace the undersized gas path pipe diameter and valve switch. Avoid reducing the line pressure.
2. Water needle breaking fault of
Air Leg Rock Drill And Gasoline Rock Drill
Reasons for water needle failure: the center hole of the drill tail is not correct, the clearance between the drill tail and the drill sleeve is too large, the water needle is too long, and the drill tail does not meet the standard size, so you want to buy a good
Air Leg Rock Drill And Gasoline Rock Drill to medium coal.
Troubleshooting: replace the drill rod if the center hole of the drill rod is not aligned; If the fit clearance between the drill rod and the drill sleeve is too large, the drill sleeve will not meet the standard if it is worn to 25 mm from the hexagon dimension. Otherwise, not only the water needle is broken by mistake, but also the drill rod is easy to be damaged, so it should be replaced in time; If the water needle is too long, it should be repaired in time. If the drill rod does not meet the standard, it should be repaired according to the standard.
3. Air water linkage failure of
Air Leg Rock Drill And Gasoline Rock Drill
The causes of failure of gas water linkage mainly include: high water pressure, blockage of gas water circuit, failure of water injection valve spring, air leakage, water leakage, rubber ring failure, corrosion of parts in water injection valve, etc.
Troubleshooting: If the water pressure is too high, pressure reduction measures shall be taken; If the air-water path is blocked, the blocked debris in the small hole of the air-water path shall be removed; If the spring of the water injection valve fails, the spring shall be replaced or repaired in time; In case of water leakage, air leakage or rubber ring failure, the sealing element shall be replaced or repaired; If the parts inside the water injection valve body are rusted, they shall be cleaned and derusted, and the faults caused by more than two reasons shall be comprehensively treated.
4. Failure of
Air Leg Rock Drill And Gasoline Rock Drill due to poor lubrication
The small hole of the oil path of the oil injector is blocked, which shall be cleaned and then blown through with compressed air. Failure caused by insufficient thrust and inflexible extension of the air leg. Replace or reassemble the worn or loose air leg rubber bowl. The frame body is not tightly connected with the outer pipe thread, and the upper and lower cavities with air leakage shall be tightened. Damaged or missing sealing rings shall be replaced in time. If the trigger is worn, the compression reversing valve is not flexible, and the
Air Leg Rock Drill And Gasoline Rock Drill is not easy to shrink, the trigger should be replaced. For the phenomenon that the water pressure is higher than the air pressure, causing the pressure water to flow back into the machine and damaging the normal lubrication, pressure reduction measures should be taken, and the main parts that do not conform to the standard should be replaced.
