Common Drilling Rig Problems: Self-Check and Troubleshooting

Common Drilling Rig Problems: Self-Check and Troubleshooting

1. Machine won't start, no response

Check power: Confirm the power switch is on and the plug is securely connected.

Check protection: Check if the external circuit breaker has tripped or if the emergency stop button is pressed.

Listen to sound: If there is no sound at all during startup, it may be an electrical problem; please have an electrician check it.

2. Drill rod doesn't turn or turns weakly

First check the belt: Check if the drive belt between the engine and the drill rod is loose, slipping, or broken.

Try it manually: If the belt is loose, tighten it appropriately; if it is severely worn, replace it with a new belt.

3. Difficult drilling, feels stuck

Immediate action: Stop applying downward pressure, lift the drill rod slightly upward, and let it idle for a moment.

Assess the situation: It may have encountered hard rock formations, or the drill bit may be stuck with mud and rocks.

Troubleshooting: Try repeatedly lifting the drill and clearing the cuttings. If this is ineffective, consider replacing it with a more powerful drill bit.

4. Abnormal vibration or increased noise from the machine body

Stop the machine immediately: Abnormal vibration usually indicates a mechanical problem.

Check for tightness: Check if any screws on the base, brackets, etc., are loose.

Inspect the drill bit: Check if the drill rod is bent, and if the drill bit is severely worn or has missing teeth.

5. Slow operation and noise in the hydraulic system

Check the oil level: Check if the hydraulic oil level in the tank is within the normal range.

Observe the oil quality: If the oil is black, cloudy, or foamy, replace it immediately.

Find leaks: Inspect all oil pipe joints and cylinders for obvious leaks.

6. Poor slag removal from the borehole

Check water/mud: Confirm that the water pump pressure is sufficient and that the pipeline is not blocked or leaking.

Adjust the flow rate: Try increasing the water or mud flow rate to help flush out debris from the borehole.

Clean the pipeline: Stop the machine, inspect and clear any blockages in the slag removal pipeline.

Safety Reminder

Always stop the machine and disconnect the power before any inspection or operation.
