Maintenance & Care Recommendations

Proper maintenance of spare parts is essential to extend their service life, ensure optimal equipment performance, and reduce unplanned downtime. Below are practical, easy-to-follow tips for daily use and maintenance, tailored to the unique needs of industrial drilling and boiler equipment:

1. Regular Inspection

Inspect filters (4N0015, P550252, SPX-06*25), seals (ф475×53, AH130101-0406), and brake components (50Dl) monthly for wear, clogging, or leakage—replace immediately if damage is found to prevent system failure. Check electrical components (DYFP-2, Viatran sensor, BK100VA) for loose connections or damage, as these can compromise equipment control. Inspect drilling bits (SWT115GC) for tooth wear after each drilling operation, as excessive wear can reduce drilling efficiency. Examine plunger pumps (FKQ6404) and mud pump pistons (BOMCO F1300/1600CP70) for fluid leakage and abnormal noise, indicating potential component wear.

2. Cleaning & Lubrication

Clean filter elements (4N0015, P550252) and oil filters (512605010111001806) every 3 months to remove debris and prevent clogging. Lubricate moving parts (winch intermediate shafts, pin shafts, bushings) with high-temperature lubricating oil to reduce friction and wear—except for self-lubricating bearings (430117010041300000), which require no additional lubrication. Flush hydraulic lines and valves (R10PH-10, KLA-L10) annually to remove contaminants and maintain fluid flow. Clean boiler centrifugal pumps (NMM 25/125BE) and pipeline filters regularly to prevent buildup and ensure efficient operation.

3. Storage Guidelines

Store spare parts in a dry, clean, and temperature-controlled environment (10-25℃) to avoid rust and damage. Seals and rubber components (ф475×53, AH130101-0406) should be stored away from direct sunlight and chemicals to prevent aging. Electronic components (DYFP-2, Viatran sensor, S-001 camera) should be stored in anti-static packaging to protect sensitive circuits. Metal components (steel tooth bits, bolts, bushings) should be coated with anti-rust oil during storage to prevent corrosion. Repair kits and small parts should be stored in organized containers to avoid loss or damage.

4. Replacement Schedule

Follow these recommended replacement intervals to ensure optimal performance and safety: Filters and filter elements every 6 months or 500 operating hours; seals and gaskets every 6-12 months (or sooner if leakage is observed); brake components (50Dl) every 12-18 months (depending on usage); mud pump pistons (BOMCO F1300/1600CP70) and plunger pumps (FKQ6404) every 24 months or during equipment overhauls; electrical components every 5 years or if performance issues arise. Drilling bits (SWT115GC) should be replaced based on drilling footage, and self-lubricating bearings every 36 months or if signs of wear are present.
