How to Use High Precision RC Gas Lift Core Drilling Rig – Portable Motorized RC Drilling Machine for Mining and Geotechnical Engineering – Customizable Depth and Features for Efficient Exploration: Complete Guide

This RC gas lift core drilling rig review includes a detailed walkthrough to help you get started quickly. We found the learning curve moderate, but the steps below will guide you through setup, operation, and maintenance.

Step 1: Initial Setup and Installation

Begin by placing the rig on a level, stable surface at your drill site. Extend the outrigger jacks and secure them to the ground to prevent movement during operation. Connect the 380V power supply to the control panel, ensuring the correct phase and voltage. Attach the compressor for the gas lift system to the designated air inlet port. Install the desired drill bit onto the bottom of the dual-wall drill string. Finally, fill the hydraulic fluid reservoir to the recommended level and check all hose connections for leaks.

Step 2: First-Time User Guide

Power on the control panel and familiarize yourself with the joystick for feed control, the rotation speed selector, and the gas lift pressure gauge. Set the rotation speed to a low setting for the initial start. Press the hydraulic feed lever to slowly lower the drill string toward the ground. Engage the rotation motor and begin drilling at a low penetration rate. Monitor the air pressure gauge; optimal gas lift operation requires a steady 80-100 PSI depending on depth.

Step 3: Core Functions and Daily Use

For standard sampling operations, maintain a consistent feed rate and rotation speed based on the rock hardness. The gas lift system will automatically transport cuttings and core samples up the drill string. As you achieve depth, add additional drill pipe sections using the included handling tools. Keep the control panel clean and dry. We found that taking breaks every 30 minutes to check the core sample integrity improves overall recovery quality.

Step 4: Advanced Techniques

Experienced operators can adjust the gas lift pressure to optimize sample recovery in fractured or unconsolidated formations. For deep boreholes, use a slower feed rate and higher rotation speed to prevent the drill string from binding. The rig also supports wireline core retrieval if you purchase the optional wireline adapter kit, which increases core sample throughput significantly.

Step 5: Maintenance and Care

After each drilling shift, clean the drill string and bit with water to remove rock dust and cuttings. Lubricate all moving parts on the feed mechanism and swivel head. Check the hydraulic oil level weekly and replace it according to the manual schedule. Inspect the gas lift seals for wear. Store the rig in a dry, covered area when not in use to protect electrical components from moisture.

Step 6: Troubleshooting Common Issues

If the gas lift fails to lift cuttings, check the compressor output and air line connections. For loss of rotation power, inspect the electric motor thermal overload switch. If the feed rate becomes inconsistent, bleed any air from the hydraulic system. For most mechanical issues, the included tool kit provides the basic tools needed for field repairs.
