5. Maintenance & Care Recommendations

To ensure long-term stable operation of our components and extend their service life, we provide professional, on-site-oriented maintenance suggestions—serving as a technical reference for operators and a procurement guide for selecting replacement parts. These recommendations help reduce maintenance costs, avoid unplanned equipment failure, and ensure operational safety:

1. Regular Inspection: For oilfield components (ASSY UPR IBOP, Dies for preventer, RVD hose, P100245HP hard seal), inspect structure integrity, sealing performance, and wear every 1.5 months. For filters (56076200, 10010PB-7996, QTL-6027), check for clogging every 30 days (or after 350 operating hours). For electrical components (SOLA SDP3-15-100T, DSE 7320 MK11, HIMC 40), test electrical performance and connections every 2.5 months. Replace damaged components promptly to avoid system failure.

2. Cleaning & Lubrication: Regularly clean component surfaces to remove dust, oil stains, and drilling mud. For bearings (BG322004-0221, NU 224 ECJ, SBW 2DZ5.5.59A-10), apply lithium-based lubricating oil (NLGI 2) every 5 months to prevent wear and jamming. For hydraulic motors and valves, replace hydraulic oil and filter elements every 5-10 months to avoid oil pollution. For electrical components, clean surfaces and terminals to prevent poor contact and overheating.

3. Replacement Standards: Filters (fuel, oil, EH turbine, cabin) should be replaced every 5-12 months (or after 700 operating hours). Seals and O-rings should be replaced every 1-2 years (or when aging, cracks, or deformation are found). High-pressure oilfield components (IBOP, hard seal, relief valve) should be replaced every 3-6 years, or earlier if damaged. Electrical components should be replaced when electrical performance fails or shells are damaged. Bearings should be replaced when wear exceeds 0.08mm or noise increases significantly.

4. Storage Requirements: Unused components should be stored in a dry, ventilated, clean warehouse—away from direct sunlight, moisture, and corrosive media. Metal components (bearings, fasteners, engine parts) should be coated with anti-rust oil to prevent corrosion. Seals and O-rings should be stored in sealed packages to avoid dust and moisture pollution. Electrical components should be stored in a dry, anti-static environment, away from strong magnetic fields. Tubing hanger seals should be stored in a cool, dry place, and their origin and conformity certificates should be kept properly.

5. Operation Specifications: Use professional tools for installation to avoid damaging threads, seals, or electrical components. For high-pressure oilfield components (IBOP, hard seal), ensure installation torque meets API 6A standards to prevent leakage. For electrical components, turn off power and discharge static electricity before replacement or maintenance. Do not modify component structures without authorization, as this may affect performance and safety. For hydraulic systems, ensure sufficient oil level before starting to avoid dry friction.

6. On-Site Fault Maintenance Cases

The following 3 real on-site fault maintenance cases demonstrate the practical applicability of our components, providing reference for users to solve similar technical problems—while highlighting the value of our products in resolving common industrial pain points and ensuring operational continuity:

Case 1: Turbine Malfunction Caused by Clogged EH Turbine Filter Cartridge QTL-6027

Fault Phenomenon: A power plant’s EH turbine experienced frequent shutdowns, with the control system displaying "low oil pressure" and "filter clogging" error codes. The turbine’s response speed slowed down, affecting power generation efficiency. Fault Cause: On-site inspection found that the EH Turbine Filter cartage QTL-6027 had not been replaced for 12 months, resulting in severe clogging by metal particles and impurities. This caused insufficient EH oil flow, leading to low oil pressure and turbine shutdown. Solution: Replace the QTL-6027 filter cartridge with our product, flush the EH oil circuit, and test the turbine system. Post-Maintenance Effect: The turbine resumed normal operation, with stable oil pressure and fast response speed. No similar faults occurred in the subsequent 14 months—reducing unplanned downtime by 48% and improving power generation efficiency by 22%.

Case 2: ZJ-20 Air System Pressure Instability Due to Faulty Combined Pressure Regulator 870902-00-0541

Fault Phenomenon: An oilfield’s ZJ-20 drilling rig air system had unstable pressure, fluctuating between 0.6-1.2MPa, causing the air-controlled components to operate abnormally and affecting drilling efficiency. Fault Cause: The Combined Pressure Regulator 870902-00-0541 for the ZJ-20 air system had a faulty pilot valve, preventing precise pressure regulation. Solution: Replace the pressure regulator with our product, adjust the pressure to the recommended range (0.8-1.0MPa), and test the air system. Post-Maintenance Effect: The air system pressure stabilized, with fluctuations within ±0.05MPa. All air-controlled components operated normally, and the drilling rig’s operational efficiency improved by 18%. No similar faults were reported after 10 months of use.

Case 3: SPM QWS-2500SD Pump Leakage Caused by Damaged Hard Seal P100245HP

Fault Phenomenon: An oilfield’s SPM QWS-2500SD pump leaked severely during high-pressure fluid transfer, with a leakage rate of 5-8L/h, posing a safety risk and wasting resources. The pump’s operating pressure dropped significantly, affecting work progress. Fault Cause: The P100245HP hard seal of the pump was worn and scratched, losing its sealing capability under 15K PSI pressure. Solution: Replace the hard seal with our product, clean the pump sealing surface, and re-torque the pump components to the recommended standard. Post-Maintenance Effect: The leakage stopped completely, and the pump operated reliably under full pressure. The pump’s operating efficiency recovered to 100%, and no leakage occurred after 9 months of continuous operation—ensuring safe, efficient fluid transfer and reducing resource waste by 100%.
