How To Prevent Malfunctions Of Pneumatic Rib Drills?

1. Air Supply System Maintenance
Stable Air Pressure: Ensure the compressed air pressure is maintained at 0.4~0.63MPa. Equip the air line with a water separator and regularly drain accumulated water to prevent moisture from damaging the pneumatic motor lubrication or blocking the exhaust port.
Air Hose Inspection: Regularly check the air hose for leaks or aging, and replace hoses with an inner diameter of ≥12mm to reduce air pressure loss.
2. Lubrication Management
Lubricator Use: Before operation, adjust the lubricator's oil output to 2-3 ml per minute. Use 30# machine oil or 3# lithium-based grease. Avoid operating without lubrication.
Bearing Lubrication: Gearbox bearings (such as 204 bearings) require regular application of grease to prevent wear caused by dry friction.
3. Drill Bit and Drill Rod Maintenance
Drill Bit Inspection: Replace worn drill bits promptly to prevent decreased drilling efficiency or motor overload.
Drill Rod Specifications: Avoid using bent drill rods. The hexagonal size of the hexagonal drill rod tail must match (e.g., 19mm).
4. Daily Cleaning and Storage
Debris Removal: After operation, clean metal chips from the surface and interior of the drill to prevent blockage of air or water passages.
Dry Storage: The storage environment must be dry to prevent metal parts from rusting or electrical components from getting damp.
5. Operating Procedures
Avoid Sudden Loading: Apply even force when drilling to prevent counter-torque from causing drill imbalance or component damage.
Idling Test: Before operation, check for abnormal noise or vibration during idling to detect bearing or gear problems in advance.
6. Regular Maintenance
Gearbox Inspection: After disassembly, check for gear pitting and bearing wear. Replace severely damaged parts.
Valve Body Maintenance: Clean the valve body and replace any defective seals or springs to ensure smooth airflow.
