• Wear Inspection: Every month, inspect the wear condition of valve cores, bearing races, brake friction pads, and seals. Replace parts if wear exceeds the limit (e.g., valve core wear more than 0.5mm, friction pad thickness less than 3mm).

• Pressure Testing: Every month, perform pressure testing on plug valves (2A29633, 2A36869) and hammer unions to ensure they can withstand operating pressure without leakage. Test the brake assembly to ensure stopping power is within specifications.

• Cleaning: Every month, clean strainer crosses (1294186) to remove debris and contaminants; clean swivels and valve bodies to prevent corrosion. Flush hydraulic lines connected to valves to remove sludge.

• Anti-Corrosion Maintenance: Every quarter, inspect the anti-corrosion coating of steel components (bearings, adapters, swivels). Reapply anti-corrosion coating if the coating is damaged or worn to prevent rust and corrosion.

3. Long-Term Storage Maintenance

• Store spare parts in a dry, ventilated, and clean warehouse, away from moisture, dust, and corrosive media (such as drilling fluid, acid, alkali). Keep the warehouse temperature between 5℃ and 30℃ to avoid extreme temperature damage.

• Coat metal parts (bearings, valves, adapters) with anti-rust oil before storage; wrap seals and O-rings in oil-resistant paper to prevent drying and cracking. For bearings, add lubricating grease to prevent rust and ensure smooth rotation when put into use.

• Regularly inspect stored spare parts every 3 months, clean and reapply anti-rust oil if necessary, and ensure that all parts are in good condition and ready for use at any time. Rotate stored parts to ensure older inventory is used first.

4. Maintenance Notes

• Maintenance personnel must receive professional training, be familiar with the structure and function of drilling machinery, and strictly follow the maintenance procedures to avoid improper operation causing damage to parts or equipment.

• Use special tools and matching auxiliary materials (lubricating oil, seals) during maintenance. Do not use inferior or incompatible materials, as this could reduce the service life of parts or cause system failure.

• Record maintenance details (time, content, replaced parts) in a log to establish a maintenance file. This helps track the use and maintenance status of parts, optimize maintenance schedules, and quickly identify potential problems.

• When replacing spare parts, ensure the new part matches the original equipment model and check the part’s quality (surface condition, dimensional accuracy) before installation. For pressure-containing components (valves, hammer unions), bleed air from the system after replacement to ensure stable operation.

On-Site Fault Maintenance Cases

Below are 4 real on-site fault maintenance cases from our oilfield customers, detailing common faults of drilling machinery, their causes, and solutions using our spare parts. These cases help you quickly identify and resolve similar problems, reduce downtime, and improve maintenance efficiency:

Case 1: Light Weight Plug Valve Leakage Causing Hydraulic System Pressure Loss

Site: An onshore oilfield drilling platform, using a hydraulic control system for wellhead equipment.

Fault Phenomenon: The hydraulic system experienced rapid pressure loss, and the wellhead control valves failed to operate properly. On-site inspection found fluid leakage around the Light Weight Plug Valve (2A29633).

Cause Analysis: The valve core and seat of the 2A29633 Plug Valve were worn due to long-term contact with drilling fluid contaminants, leading to poor sealing and leakage. The valve had not been inspected or replaced for over 12 months, exacerbating the wear.

Solution: Replace the worn Light Weight Plug Valve with our new 2A29633 model. Clean the hydraulic line to remove contaminants, inspect and replace the O-ring (K465J56) for the valve, and perform pressure testing to ensure no leakage. After replacement, the hydraulic system maintained stable pressure, and the wellhead control valves operated normally. The drilling operation resumed within 1 hour.

Experience Summary: Regularly inspect plug valves for wear and contamination, especially in systems with drilling fluid. Replace valves and seals every 12 months or sooner if leakage is detected to avoid pressure loss and operational disruptions.

Case 2: Bearing Failure Causing Rotary Table Vibration

Site: An offshore drilling platform, using a rotary table equipped with BEARING K531-006.

Fault Phenomenon: The rotary table produced abnormal noise and severe vibration during operation, and the drill pipe rotation became unstable. The vibration increased over time, threatening the safety of on-site personnel.

Cause Analysis: Disassembly inspection found that BEARING K531-006 was severely worn, with damaged rolling elements and raceways. This was caused by insufficient lubrication and contamination from drilling fluid, which entered the bearing through a damaged seal.

Solution: Replace the worn bearing with our new BEARING K531-006. Clean the rotary table shaft and bearing installation position, replace the damaged seal (80149-BR), and add API GL-4 lubricating grease. After replacement, the abnormal noise and vibration disappeared, and the rotary table operated smoothly. The drilling operation resumed within 2.5 hours.

Experience Summary: Regular lubrication and seal inspection are critical for bearings in offshore environments. Follow the weekly lubrication schedule and daily seal inspection to prevent contamination and bearing failure.

Case 3: Brake Assembly Wear Causing Stopping Failure

Site: A deep well drilling site, using a 22SR series drawworks equipped with 22SR BRAKE ASSEMBLY C.C.W D631778-X.

Fault Phenomenon: The drawworks brake failed to provide sufficient stopping power, and the drill pipe could not be securely held during make-up/break-out operations. This posed a serious safety hazard and forced the drilling operation to stop.

Cause Analysis: Inspection found that the friction pads of the 22SR BRAKE ASSEMBLY (D631778-X) were completely worn, and the brake fluid had leaked due to a damaged seal. The brake assembly had not been inspected for over 8 months, leading to the failure.

Solution: Replace the worn brake assembly with our new 22SR BRAKE ASSEMBLY C.C.W D631778-X. Refill the brake system with clean brake fluid, replace the damaged seal, and test the brake stopping power. After replacement, the brake operated reliably, and the drawworks could securely hold the drill pipe. The drilling operation resumed within 3 hours.

Experience Summary: Inspect brake assemblies monthly for friction pad wear and fluid leakage. Replace brake assemblies or friction pads before they reach the wear limit to ensure operational safety.

Case 4: Seal Leakage Causing Gearbox Oil Loss

Site: An onshore drilling platform, using a mud pump gearbox equipped with SEAL OIL YS-6870.

Fault Phenomenon: The mud pump gearbox experienced severe oil leakage, leading to low oil levels and abnormal gear noise. If not resolved, this would have caused gear damage and pump failure.

Cause Analysis: The SEAL OIL YS-6870 was worn and cracked due to high operating temperatures and long-term use (over 10 months). The oil leakage was not detected in daily inspections, leading to low oil levels and gear wear.

Solution: Replace the worn oil seal with our new SEAL OIL YS-7000 (compatible with the gearbox and more heat-resistant than YS-6870). Refill the gearbox with the recommended lubricating oil, clean the gearbox surface, and inspect for additional leaks. After replacement, the oil leakage stopped, and the gearbox operated normally without abnormal noise.

Experience Summary: Use heat-resistant seals (like YS-7000) in high-temperature components such as gearboxes. Inspect oil seals daily for leakage and replace them every 8-10 months to prevent oil loss and component damage.
