On-Site Fault Maintenance Cases
The following 3 real on-site fault cases provide practical guidance for solving common oilfield equipment problems, helping maintenance teams quickly diagnose and resolve issues, and minimizing downtime (average resolution time ≤1.3 hours):
Case 1: ZJ-70 Drilling Rig Hydraulic Pressure Instability
Fault Phenomenon: A ZJ-70 drilling rig’s hydraulic system experiences unstable pressure (fluctuating between 80MPa and 100MPa), leading to erratic operation of the winch. Inspection shows the Pressure Reducing Valve 4900350154 is clogged with debris, affecting pressure regulation.
Solution: Disassemble the 4900350154 valve, clean the valve core and internal passage with high-pressure air, and reinstall it. Calibrate the valve to the standard pressure range (90-95MPa). After maintenance, the hydraulic pressure stabilizes, and the winch operates smoothly—resolving the issue in 1.2 hours.
Case 2: SK-2Z16 Host Fan Failure & Equipment Overheating
Fault Phenomenon: A ZJ-70D drilling rig’s host equipment overheats (temperature exceeds 95°C), causing frequent shutdowns. Inspection confirms the SK-2Z16 Host Fan 120mm is faulty, with reduced air flow (below 600m³/h) due to a damaged motor.
Solution: Replace the faulty SK-2Z16 host fan with a new 120mm model, clean the fan housing, and test air flow (ensuring it reaches 1200m³/h). After replacement, the host equipment temperature drops to 65°C, and shutdowns are eliminated—resolving the issue in 1 hour.
Case 3: ZJ-45 Drilling Rig Hydraulic Leakage
Fault Phenomenon: A ZJ-45 drilling rig’s hydraulic system has severe leakage, leading to pressure loss (from 100MPa to 58MPa). Inspection reveals the O-Type Sealing Ring ZJ-45 PSZ75B Φ24×2.4 is worn and cracked.
Solution: Replace the worn sealing ring with a new ZJ-45 PSZ75B Φ24×2.4 model, clean the sealing surface, and apply a thin layer of lubricating grease to ensure a tight seal. After replacement, the leakage is completely eliminated, and the hydraulic system pressure returns to 100MPa—resolving the issue in 1.5 hours.
