Desert environments are characterized by dryness, sand, strong winds, and significant temperature variations, all of which impose strict maintenance requirements on rotary drilling rigs. Without proper maintenance tailored to these conditions, equipment is prone to accelerated wear or even premature failure. To ensure efficient operation and prolong the service life of rotary drilling rigs, it is essential to implement specific maintenance measures for key components such as wire ropes, drill bits, tracks, drill rods, rotary heads, and engines.
Prevent Sand Erosion: Sand easily adheres to the surface of wire ropes, increasing wear and reducing lifespan. After operations, clean the ropes thoroughly, and rinse them with water if necessary, ensuring they are completely dry.
Regular Lubrication: The dry desert environment accelerates lubricant evaporation. Use high-temperature and dust-resistant grease, applying it regularly to keep the wire ropes well-lubricated.
Check for Wear: Inspect wire ropes for wear, broken strands, or fatigue before and after operations. Replace damaged ropes promptly to ensure operational safety.
Prevent Excessive Wear: Drill bits wear out faster in sandy soils. Choose materials suitable for sandy layers and inspect bit wear regularly, replacing them when necessary.
Cleaning and Anti-Rust Measures: Sand and high temperatures can corrode drill bits. After operations, clean off sand and dirt, and apply anti-rust oil before storage.
Inspect Connections: Regularly check the connections between drill bits and rods to prevent loosening or breakage due to wear.
Prevent Sand Accumulation: Sand easily accumulates inside the tracks, causing operational difficulties and wear. Clear sand and debris from the tracks daily to maintain smooth operation.
Lubrication and Tensioning: Tracks lose lubrication quickly in desert conditions. Reapply grease regularly and check track tension to prevent derailment or excessive wear.
Inspect Undercarriage: Regularly inspect the rollers and drive wheels for abnormal wear or blockages and replace them as needed.
Regular Cleaning: Sand adheres to drill rods, so clean them thoroughly after operations and check for bending or cracks.
Anti-Rust Treatment: Despite the dry heat, high humidity at night can cause rust on drill rods. Apply anti-rust agents regularly and store rods in dry, shaded areas.
Maintain Connection Threads: Clean and lubricate the threaded connections frequently to ensure secure and smooth assembly.
Seal Inspection: Sand entering the rotary head can damage the hydraulic system. Regularly check seals to ensure the hydraulic system is properly enclosed.
Lubrication and Cooling: High temperatures can overheat the rotary head. Use high-quality lubricants and ensure the cooling system functions effectively. Consider adding coolant or auxiliary cooling devices if necessary.
Bolt and Gear Checks: Regularly inspect bolts and gears in the rotary head to prevent malfunctions caused by looseness or wear.
Dust Filtration: Dust poses a significant threat to the engine. Clean air filters regularly and add extra filtration layers if necessary to prevent sand from entering the engine.
Cooling System Maintenance: The desert heat can overheat engines. Ensure the cooling system operates efficiently, replace coolant regularly, and avoid shutting down the engine immediately when it is hot.
Fuel and Oil Selection: Use fuel and lubricants designed for high-temperature environments. Inspect their quality frequently and replace them promptly to maintain engine performance.
