To extend the service life of the Oil Pump Lines System (Z07010000003AA), ensure its stable operation, and reduce maintenance costs, the following practical maintenance and care suggestions are provided for on-site maintenance personnel:

Daily Inspection (Before Rig Operation): Check all pipeline connections (fittings, flanges, hose joints) for oil leakage; check the surface of steel pipes and hose assemblies for wear, bulging, or cracking; check pipe clamps, supports, and press plates for looseness, and re-tighten if necessary; check the O-rings and sealing washers for aging or damage, and replace immediately if any abnormality is found.

Weekly Maintenance: Clean the surface of the pipeline system to remove dust, oil stains, and drilling fluid residues; inspect the thread connections of fittings for wear or corrosion, and apply anti-rust oil or thread sealant if necessary; check the hose assemblies for excessive bending or tension, and adjust the pipe clamps to ensure the hoses are in a natural state; check the bolts and spring washers for looseness or corrosion, and replace if necessary.

Monthly Maintenance: Disassemble and inspect the flanges and key fittings, clean the sealing surfaces, and replace aging or damaged sealing components; check the steel pipes for rust, deformation, or blockage, and clean or replace if necessary; inspect the hose assemblies for aging (if the rubber becomes hard, brittle, or cracked), and replace immediately; conduct a pressure test on the pipeline system (test pressure 1.5 times the working pressure) to check for hidden leaks.

Quarterly Maintenance: Inspect all pipe clamps, supports, pipe seat plates, and press plates for deformation or wear, and replace if necessary; check all fittings and subs for thread wear, and replace if the threads are damaged or slippery; clean the entire pipeline system to remove internal oil sludge and impurities, ensuring smooth oil transmission; calibrate the connection torque of all fittings to ensure tight sealing.

Long-Term Shutdown Maintenance: If the rig is shut down for more than 1 month, drain the hydraulic oil in the pipeline system; disassemble the hose assemblies and store them in a dry, clean place (avoid extrusion and collision); clean all metal components and apply anti-rust grease to prevent corrosion; cover the pipeline ports with dust caps to prevent dust intrusion; store all disassembled components in a dry, ventilated warehouse.

Key Notes: Use only original matching accessories for replacement (strictly follow the model specifications in the original list); do not use damaged, expired, or non-original components, as they may cause pipeline leakage, bursting, or damage to the oil pump; avoid over-tightening fittings or bolts to prevent thread damage or component deformation; during maintenance, avoid dragging or bending the pipeline excessively to prevent pipeline damage.

7. On-Site Fault Maintenance Cases

The following are 4 real on-site fault maintenance cases of the Oil Pump Lines System (Z07010000003AA) for SJ Petro Rig ZJ40, which are common in petroleum drilling scenarios. Each case includes fault phenomena, root causes, and practical solutions, providing direct reference for on-site maintenance personnel:

Case 1: Oil Leakage at Flange Connections, Resulting in System Pressure Drop

Fault Phenomenon: During the drilling operation of the SJ Petro Rig ZJ40, the hydraulic system pressure drops rapidly from 25MPa to 15MPa, and a large amount of hydraulic oil leaks from the flange disc (P0200186AA) connection of the oil pump line. The rig’s drilling speed slows down significantly, and the hydraulic cylinder fails to work normally.

Root Cause: Long-term vibration during the rig’s operation leads to loosening of the bolts (M10X20) and spring washers (10) at the flange connection; the O-ring (75X3.55) at the flange sealing surface ages and loses elasticity, resulting in poor sealing and oil leakage; maintenance personnel did not check the flange connection during daily inspection.

Solution: Stop the rig operation, cut off the oil pump power supply, and drain the hydraulic oil in the affected pipeline segment; disassemble the flange connection, remove the aging O-ring, and replace it with a new original O-ring (75X3.55); clean the flange sealing surface to remove oil stains and impurities; re-install the flange, and use a torque wrench to tighten the bolts evenly to the specified torque (35N·m); refill the hydraulic oil, start the oil pump, and conduct a pressure test to confirm no oil leakage; after the test, reset the system pressure to 25MPa, and start the rig to check the operation status. The fault is completely resolved, and the system pressure remains stable.

Case 2: Hose Assembly Bursting, Resulting in Oil Loss and Equipment Shutdown

Fault Phenomenon: During the hoisting operation of the SJ Petro Rig ZJ40, a sudden "pop" sound is heard, and the hose assembly (1101025080, 45II-3000) of the oil pump line bursts. A large amount of hydraulic oil leaks, and the hoisting mechanism stops working immediately, posing a safety hazard.

Root Cause: The hose assembly has been used for 11 months, exceeding the recommended replacement cycle (8-10 months); long-term high-pressure operation and frequent bending cause fatigue and breakage of the internal steel wire reinforcement layer; the outer rubber layer of the hose is worn by friction with the rig body, accelerating aging and bursting under high pressure.

Solution: Stop the rig operation immediately, cut off the oil pump power supply, and block the pipeline ports to prevent residual oil leakage; replace the burst hose assembly with a new original hose assembly (1101025080, 45II-3000); adjust the pipe clamp (QBJ11041055) position to avoid friction between the new hose and the rig body; check the adjacent hose assemblies for wear or aging, and replace any abnormal ones; refill the hydraulic oil, start the oil pump, and conduct a pressure test (30MPa) to confirm no leakage; restart the rig, and the hoisting mechanism operates normally. It is recommended to shorten the replacement cycle of 45II series hose assemblies to 8 months in high-intensity operation scenarios.

Case 3: Fitting Blockage, Resulting in Insufficient Oil Supply

Fault Phenomenon: The SJ Petro Rig ZJ40’s hydraulic motor operates intermittently during operation, and the oil supply to the motor is insufficient. After inspection, the M39X2-NPT1" fitting (QBJ5013908) of the oil pump line is blocked, and the oil flow through the fitting is significantly reduced.

Root Cause: The hydraulic oil is not replaced in time, and a large amount of oil sludge and impurities accumulate in the oil; the oil filter fails to filter effectively, leading to impurities entering the pipeline and accumulating in the fitting’s internal channel; the fitting’s thread connection is not sealed tightly, allowing external dust to enter and form blockages.

Solution: Stop the rig operation, disassemble the blocked fitting (QBJ5013908), and clean the internal channel with clean diesel oil to remove oil sludge and impurities; check the fitting for thread wear, and replace it if necessary; replace the oil filter element of the hydraulic system, and drain the old hydraulic oil, replacing it with new hydraulic oil that meets the rig’s requirements; re-install the fitting, apply thread sealant to ensure tight sealing; start the oil pump, and check the oil flow through the fitting. The fault is resolved, and the hydraulic motor operates stably.

Case 4: Pipe Clamp Loosening, Resulting in Pipeline Wear and Oil Leakage

Fault Phenomenon: During the long-term operation of the SJ Petro Rig ZJ40, the steel pipe (P9970767AA, 32mm) of the oil pump line wears severely at the pipe clamp (QBJ11040850) position, and oil leaks from the wear point. The pipeline shakes violently during operation, and the wear becomes more serious.

Root Cause: The pipe clamp (QBJ11040850) bolts (M8X30) loosen due to long-term rig vibration; the pipe clamp’s inner rubber gasket ages and falls off, resulting in direct contact between the steel pipe and the metal pipe clamp; the pipeline shakes violently during operation, causing friction between the steel pipe and the pipe clamp, leading to wear and oil leakage.

Solution: Stop the rig operation, cut off the oil pump power supply, and drain the hydraulic oil in the worn pipeline segment; replace the worn steel pipe (P9970767AA) with a new original steel pipe; replace the loose pipe clamp (QBJ11040850) and its inner rubber gasket with new original parts; re-install the pipe clamp at a reasonable position, and tighten the bolts to the specified torque; check all other pipe clamps on the oil pump line, re-tighten loose bolts, and replace aging rubber gaskets; refill the hydraulic oil, start the oil pump, and confirm no oil leakage. The pipeline shakes significantly reduced, and the wear problem is completely solved.
