2. Safety Information

Operating heavy machinery requires strict adherence to safety protocols to prevent injury or damage. Read and understand all safety warnings before operating this drilling rig.

• Always wear appropriate Personal Protective Equipment (PPE), including hard hat, safety glasses, hearing protection, and steel-toed boots.
• Ensure the drilling site is clear of obstructions, underground utilities, and personnel not involved in the operation.
• Inspect the rig thoroughly before each use for any signs of damage, leaks, or loose components.
• Do not operate the rig under the influence of alcohol or drugs.
• Maintain a safe distance from moving parts and the drilling area during operation.
• Secure the rig on stable, level ground before commencing drilling operations.
• Familiarize yourself with emergency stop procedures and the location of all controls.
• Ensure proper ventilation when operating the engine in enclosed spaces.

3. Key Components

The D-SJZJ10 drilling rig consists of several integrated systems designed for efficient borehole creation.

• Drilling Mast: Supports the drill head and drill pipe, guiding the drilling process.
• Drill Head: Provides rotational force and downward pressure for drilling.
• Power Unit: Integrated turbocharged engine and dual oil pump system for stable power.
• Hydraulic System: Powers the drilling functions, including mast elevation, drill head movement, and stabilization.
• Crawler Chassis: Provides mobility and stability on uneven terrain.
• Control Panel: Centralized interface for operating the rig.
• Stabilizer Jacks: Four hydraulic jacks for leveling and securing the rig during operation.
• Winch: 30KN mechanical winch for lifting and lowering drill pipes and tools.

4. Setup and Preparation

1. Site Selection: Choose a drilling location that is stable, level, and free from overhead or underground obstructions. Ensure adequate space for rig operation and material handling.
2. Positioning the Rig: Drive the rig to the desired drilling spot using the crawler chassis. Position it so the drilling mast is aligned with the intended borehole location.
3. Leveling and Stabilization:
   • Engage the parking brake.
   • Extend the four hydraulic stabilizer jacks until the rig is firmly supported and level. Use a spirit level to ensure precise leveling.
   • Ensure all jacks are fully extended and bearing weight to prevent movement during drilling.
4. Fuel and Fluid Checks: Verify engine oil, hydraulic fluid, and fuel levels are adequate before starting. Replenish if necessary using recommended fluids.
5. Pre-Operation Inspection: Conduct a visual inspection of all hoses, connections, and mechanical components for wear, damage, or leaks. Tighten any loose fasteners.
6. Drill Pipe and Bit Attachment: Select the appropriate drill bit for the geological formation. Securely attach the first drill pipe and bit to the drill head.

5. Operating Instructions

The D-SJZJ10 rig offers both pneumatic (air) and hydraulic (water/mud) drilling capabilities. Select the appropriate method based on ground conditions.

5.1 Starting the Rig

1. Ensure all safety checks from Section 4 are complete.
2. Turn the ignition key to start the engine. Allow the engine to warm up for a few minutes.
3. Engage the hydraulic pump from the control panel.

5.2 Drilling Procedure

1. Initial Penetration: Slowly lower the drill head until the drill bit makes contact with the ground. Begin rotation at a low speed.
2. Applying Downward Pressure: Gradually increase downward pressure using the hydraulic controls. Monitor the drilling progress and adjust pressure as needed.
3. Controlling Rotation Speed: Adjust the drill head rotation speed (14 to 650 rpm) based on the material being drilled. Harder formations require lower speeds and higher torque.
4. Flushing (Air or Water):
   • Air Drilling: Connect an air compressor to the rig's air inlet. Use compressed air to clear cuttings from the borehole.
   • Water/Mud Drilling: Connect a water pump or mud pump to the rig's water/mud inlet. Circulate water or drilling mud to lubricate the bit, cool the borehole, and transport cuttings to the surface.
5. Adding Drill Pipes: As drilling progresses, add additional drill pipes by stopping rotation, retracting the drill head, connecting a new pipe, and then resuming drilling. Use the winch for handling heavy pipes.
6. Monitoring Parameters: Continuously monitor drilling depth, pressure gauges, and engine performance on the control panel.
7. Reaching Target Depth: Once the desired depth is reached, stop drilling, retract the drill string, and prepare for well casing or other completion procedures.

6. Maintenance

Regular maintenance is crucial for the longevity and optimal performance of your drilling rig. Follow these guidelines for routine care.

• Daily Checks:
  • Inspect hydraulic hoses and fittings for leaks or damage.
  • Check engine oil, coolant, and hydraulic fluid levels.
  • Clean the rig of mud, debris, and cuttings.
  • Inspect drill pipes and bits for wear or damage.
• Weekly/Bi-Weekly Checks:
  • Lubricate all grease points on the mast, drill head, and chassis.
  • Check air filters and fuel filters; clean or replace as needed.
  • Inspect electrical connections for corrosion or looseness.
• Monthly/Seasonal Checks:
  • Change engine oil and oil filter.
  • Inspect hydraulic fluid and filter; replace if contaminated or at recommended intervals.
  • Check and adjust track tension on the crawler chassis.
  • Inspect all structural welds for cracks or fatigue.
• Storage: When storing the rig for extended periods, clean it thoroughly, apply rust preventative to exposed metal parts, and cover it to protect from elements.
