Common Faults And Troubleshooting Of Air Leg Rock Drill

1. Main reasons for lower drilling speed of air leg rock drill:

The main reasons for the reduction of drilling speed are low pressure in the working environment, poor lubrication of the machine, insufficient thrust of the gas legs, poor expansion, large recoil of the machine, poor water passage, running water and washing hammer, wear of the main components, and there are also two or more reasons caused by the cross. For the failure of drill speed reduction, must carefully observe, comprehensive analysis.

2. Troubleshooting of air leg rock drill:

Fault caused by low working pressure of air leg rock drill. The elimination method is as follows: to calculate whether the pressurized gas line is overloaded, the number of working machines can be reduced according to the actual situation, or other gas consumption operation items can be reduced. Eliminate the factors of reducing pressure caused by pipeline leakage, check and remove leakage pipeline and joint.

Failure of pneumatic leg rock drill due to poor lubrication. Its eliminate method: oiler oil path small hole is blocked, should clean after blow through with pressure air. The fault caused by insufficient thrust of air leg and poor expansion. To replace or reassemble the worn or loose air leg rubber bowl, the frame body and the thread of the outer pipe are not tightly connected, and the upper and lower cavities should be tightened if gas passes through them. Damaged or lost seals should be replaced in time. Plate machine wear, compression valve is not working, the air leg is not easy to contract, should be replaced. For water pressure higher than air pressure, resulting in pressure water back flow to the machine, damage the normal lubrication phenomenon, to take the measures to reduce pressure, the main parts do not conform to the standard to replace.
