​Operating Faults and Solutions for Multi Functional Anchoring Drilling Rig

Operating Faults and Solutions for Multi Functional Anchoring Drilling Rig

Excessive Swinging During Drilling with the Multi Functional Anchoring Drilling Rig

Causes: Deformed or bent drill rod; worn chuck sleeve; worn air leg.

Solutions: Use qualified drill rods; check the chuck sleeve for wear and replace the spindle if worn.

Failure to Push and Install the Anchor Rod into Position

Causes: Insufficient manual thrust; misalignment between the drilling rig and the anchor hole; use of unsuitable resin cartridges or bent anchor rods.

Solutions: Increase manual thrust; align the Multi Functional Anchoring Drilling Rig with the anchor hole; check if the resin cartridges meet requirements and use qualified anchor rods.

Low Thrust from the Air Leg or Failure to Stabilize at the Set Point

Causes: Blocked air passage; leaking exhaust valve; damaged seals in the air leg.

Solutions: Check the air intake passage of the air leg to ensure smooth airflow; inspect the seals of the exhaust valve for damage and replace if necessary; check the seals of the air leg for wear and replace worn parts.

High Reaction Torque Felt on the Handle During Drilling

Causes: High air pressure, low water pressure; damaged drill bit; sudden increase in thrust during operation.

Solutions: Check if air and water pressure values are normal; inspect and replace damaged drill bits; improve operating methods to ensure smooth operation.

Slow Motor Rotation  

Causes: Low air pressure; blockage or severe air leakage in the intake pipeline.

Solutions: Check air pressure, which should be 0.4–0.63 MPa; clear any blockages in the intake pipeline by blowing it clean, clean or replace the filter and screen, or replace the intake pipe.

Reduced Drilling Speed of the Multi Functional Anchoring Drilling Rig

Causes: Low air pressure; use of unsuitable drill bits; excessive wear of the drill bit; hard rock formation; low water pressure; severe wear of bearings or gears.

Solutions: Check air pressure and ensure it reaches a reasonable value; use appropriately matched drill bits; reduce rotation speed and increase air leg thrust; check water pressure, which should be 0.6–1.2 MPa.
