• Onshore & Offshore Drilling Sites: All components resist saltwater corrosion, high humidity (80-95% RH), and drilling fluid erosion (oil-based, water-based mud)—making them suitable for coastal, offshore, and inland drilling operations.

• Harsh Industrial Drilling Environments: Resistant to dust, mechanical impact, and extreme temperature changes, our parts perform reliably in rugged land drilling sites with continuous operation and heavy equipment vibration.

Maintenance & Care Recommendations

Proper maintenance of drilling spare parts is critical to extending service life, reducing replacement costs, and preventing unplanned equipment failure. Below are practical, on-site actionable guidelines aligned with drilling rig maintenance best practices—designed for ease of implementation by on-site technicians:

• Regular Inspection (60-100 Working Hours): Conduct visual and functional checks of all wear-prone parts—inspect GLYW-160X50 fine oil filters and 1200519225 suction filters for clogging; check PS702407-00 hydraulic disc brake pads for friction material wear (replace when thickness ≤3mm); inspect ZP050018 spring oil seals and gaskets for cracking or leakage; test ex-proof electrical components for proper operation.

• Filtration System Maintenance: Replace filter elements of fine oil filters (GLYW-160X50), returning oil filters (PS600300), and pipeline oil filters (PS600900, PS601900) every 500 working hours; clean suction filter (1200519225) elements monthly to prevent clogging and ensure adequate fluid flow—clogged filters cause system pressure spikes and component damage.

• Lubrication & Sealing: Apply high-temperature, high-pressure lithium-based grease to grease fittings (61302011152101000 M10×1) and mechanical components (sprockets, rollers) every 100 working hours; apply anti-seize compound to adjusting shims and bearing press caps (T103-002.20) to prevent corrosion and seizing, especially in offshore environments.

• Electrical Component Care: Keep ex-proof emergency lamps (GBYL-Y2X20) and fluorescent lights (BAY51-2X40) clean and free of dust/mud to ensure optimal light output; check thermo relays (3UA5940-2E) monthly to verify temperature settings are correct—incorrect settings can lead to electrical system overheating.

• Timely Replacement of Worn Parts: Replace brake assemblies (AC225002-3200) and clutch assemblies (AD450001-2200B1) if signs of wear or damage are found; replace spring oil seals (ZP050018) and gaskets (T103-003.04) immediately if leakage is detected—delayed replacement causes fluid loss and system failure; replace plungers (T103-002.17) and rollers (T103-003.16.00) if deformation or wear is present.

• Proper Storage of Spare Parts: Store all spare parts in a dry, well-ventilated area (relative humidity <60%) away from direct sunlight and drilling fluid/mud. Keep filter elements and electrical components in original packaging to prevent contamination; store sealing parts in a cool environment to avoid rubber aging.

On-Site Fault Maintenance Cases

Below are 3 real, short on-site drilling rig fault cases—reflecting common issues faced by drilling teams—demonstrating how our direct-fit spare parts resolve critical problems quickly, minimize downtime, and restore operational efficiency:

Case 1: JC70DB Drawworks Hydraulic System Failure

A drilling site experienced sudden hydraulic system pressure loss in their JC70DB drawworks, causing the drawworks to stop operating. Inspection revealed a clogged GLYW-160X50 fine oil filter, which restricted fluid flow and triggered a system shutdown—caused by delayed filter element replacement and contaminated hydraulic oil. Solution: Replaced the GLYW-160X50 fine oil filter with our OEM-compatible part, drained and replaced the hydraulic oil, and installed a secondary inline filter to prevent future contamination. The drawworks resumed full functionality within 45 minutes, avoiding a costly multi-hour shutdown.

Case 2: DG450 Hook Brake Failure

A DG450 hook experienced brake failure during hoisting operations, posing a significant safety risk. Inspection found that the AC225002-3200 brake assembly’s friction material was completely worn, and the adjusting shims (BG322004-0212) were misaligned—caused by improper maintenance and lack of regular inspection. Solution: Replaced the AC225002-3200 brake assembly and adjusting shims with our direct-fit parts, aligned the brake components, and adjusted the brake clearance to OEM specifications. The hook resumed safe, reliable braking within 1 hour, ensuring no safety incidents or operational delays.

Case 3: ZJ70D Driller’s Cabin Ex-Proof Light Malfunction

The EX-proof emergency lamp (GBYL-Y2X20) and Ex-proof fluorescent light (BAY51-2X40) in a ZJ70D driller’s cabin failed to operate, creating a safety hazard in the hazardous environment. The issue was traced to a faulty thermo relay (3UA5940-2E) that had tripped and failed to reset, cutting power to the lights—caused by electrical overheating from dust accumulation. Solution: Replaced the 3UA5940-2E thermo relay with our compatible part, cleaned the electrical connections, and installed a dust cover to prevent future accumulation. The lights resumed normal operation within 30 minutes, restoring safety to the driller’s cabin.
