Common Operational Faults and Solutions for Multi Functional Anchoring Drilling Rig

Common Operational Faults and Solutions for Multi Functional Anchoring Drilling Rig

1.Excessive Swing During Drilling:

Causes: Bent drill rod; Worn chuck sleeve; Worn air leg.

Solutions: Use qualified drill rods; Check and replace worn chuck sleeve or spindle.

2.Failure to Push and Install Anchor Rod Properly:

Causes: Insufficient manual thrust; Misaligned drilling rig; Use of improper resin cartridge or bent anchor rod.

Solutions: Increase manual thrust; Align the Multi Functional Anchoring Drilling Rig with the borehole; Check resin cartridge quality and use qualified anchor rods.

3.Weak Air Leg Thrust or Unstable Positioning:

Causes: Air flow obstruction; Leaking exhaust valve; Damaged air leg seal.

Solutions: Inspect air intake circuit of the Multi Functional Anchoring Drilling Rig; Check/replace exhaust valve seals; Replace worn air leg seals.

4.Excessive Counter Torque Felt on Handle:

Causes: High air pressure/low water pressure; Damaged drill bit; Sudden thrust increase during operation.

Solutions: Check/adjust air and water pressure; Replace damaged bit; Maintain steady operation.

5.Slow Motor Rotation:  

Causes: Low air pressure; Blocked air hose or severe leakage.

Solutions: Maintain air pressure at 0.4-0.63MPa; Clear blockages from air hose and clean/replace filters.

6.educed Drilling Speed:  

Causes: Low air pressure; Improper drill bit selection; Severely worn bit; Hard rock formation; Low water pressure; Worn bearings/gears.

Solutions: Adjust air pressure; Use proper drill bit; Reduce rotation speed while increasing air leg thrust; Maintain water pressure at 0.6-1.2MPa.
