Drill Rigs FAQ

  1. Q: What is the fault of too slow drilling speed?

A: 1) The air volume is insufficient and the air pressure is too low. Increase the air supply volume and check the connector for air leakage.

2) If the air supply pipeline is small or too long, replace the air duct and shorten the air circuit.

3) The thrust is insufficient, and the thrust is increased.

4) The drill hole is displaced, and the resistance of the impactor and drill pipe is too large when they are running at the edge. Adjust the rack immediately, reduce the thrust, move up and down while rotating, and trim the hole wall.

5) The drill bit is blunt, and it should be repaired or replaced.

6) The internal parts of the impactor are worn. Check and replace them after cleaning.

7) If there is too much water in the air bag or the pipeline freezes in winter, the air bag shall be drained to remove the ice.

  1. Q: What is the fault of drill pipe run out?

A: It is possible to drop rocks or pass through the intersection of rock changes, or drop alloy sheets; If the alloy sheet falls into the fault, the alloy sheet can be squeezed into the fault. If it cannot be taken out, the above method shall be adopted
