Proper operational procedures are critical for maintaining efficiency and safety in water well drilling machines. As core components of rigs for drilling, drill bits and tooling systems endure extreme mechanical stresses during operation, necessitating rigorous quality control. Hengwang Group, a leader in subsurface engineering solutions, outlines essential precautions for pneumatic drill rig operations and conventional drilling practices:

Pre-Operation Verification‌

Inspect down-the-hole hammer assemblies, casing adapters, and casing shoes for secure connections before deploying tools. Ensure eccentric bits rotate freely and verify pneumatic pathways in pneumatic drill rigs are unobstructed. Hengwang Group recommends using laser-aligned coupling systems to minimize vibration-induced failures.

Real-Time Monitoring‌

During drilling, monitor casing advancement and cuttings removal efficiency. Optimize air-flushing intervals by limiting upward tool movement to 10-15% of the borehole diameter. Avoid aggressive extraction forces in water well drilling machines to prevent tool deformation or borehole collapse.

Controlled Tool Retrieval‌

Conclude drilling cycles with thorough borehole purging to eliminate residual debris. For tool replacement, engage low-speed reverse rotation while applying calibrated upward force (typically 15-20% of operational torque). Cease rotation once the eccentric bit retracts flush with the casing shoe, as per Hengwang Group’s standardized retrieval protocols.

Debris Management‌

Persistent cuttings accumulation may jam eccentric bit mechanisms. If standard extraction fails, reactivate compressed air supply to clear obstructions and briefly re-engage the down-the-hole hammer. Hengwang Group’s automated pressure modulation systems in modern rigs for drilling prevent such incidents through real-time cuttings volume analysis.
