Product Introduction

This product lineup integrates well control core components, hydraulic control modules, transmission parts, sealing assemblies, pipeline fittings and monitoring sensors, covering all vulnerable components of drilling rig power transmission, hydraulic circulation and well control systems. Key products feature 5.5-inch die plates, dual safety valve blocks, torque amplification devices, gear shafts, brake flanges and temperature detection sensors. All structural parts adopt hot-forged integral molding, while sealing components use precision machined O-rings and external packing sets. Every finished part undergoes strict pressure holding tests and load fatigue tests to match the high stability requirements of long-cycle oilfield operations, achieving full compatibility with mainstream drilling and well control supporting equipment.

Functional Description

Each component undertakes targeted functional roles in drilling mechanical and hydraulic systems. The dual safety valve block and overflow valve jointly regulate hydraulic system pressure, preventing equipment damage caused by instantaneous overpressure. Torque amplification devices and gear shaft assemblies stabilize power transmission and solve insufficient output torque during heavy-load operation. External sealing packing and precision sealing glands form multi-layer sealing protection to isolate hydraulic oil leakage and external dust intrusion. Suspension bolts and mounting bases fix structural components to eliminate displacement and vibration deviation. API 9A standard pressed ropes bear heavy hoisting loads, while temperature sensors monitor equipment operating status in real time to avoid overheating faults.

Structural Characteristics

All spare parts adopt field-optimized structural design tailored for high-vibration and high-pressure oilfield environments. The dual-circuit safety valve block structure achieves dual overpressure protection, improving hydraulic system safety redundancy compared with single valve structures. Reinforced shear-resistant pins and anti-loosening gaskets effectively prevent part loosening and falling under long-term mechanical resonance. Integrated suspension bracket assemblies reduce on-site assembly gaps and improve overall structural stability. Multi-specification pipe crimping fittings adopt thickened wall structures to resist pipeline deformation under hydraulic impact, while symmetric left and right cheek plate structures ensure balanced equipment operation force.

Applicable Working Conditions

This series of spare parts adapts to onshore oil and gas drilling, workover and well control emergency scenarios, stably operating under working pressure up to 35MPa and ambient temperatures ranging from -40℃ to 60℃. It perfectly matches conventional medium and large drilling rig motor pump combined systems and DQ027 series preventer supporting equipment, capable of continuous stable operation in high-dust, humid and muddy harsh field environments.

Maintenance Guidelines & Field Engineer Tips

Professional field engineers recommend inspecting safety valve groups, sealing assemblies and transmission gear parts every 180 hours of continuous operation. Replace aging external packing and deformed O-rings timely to avoid slow hydraulic leakage. Clean oil return filter gaskets and flushing pipelines regularly to prevent oil circuit blockage. Avoid long-term overpressure startup of hydraulic systems to protect valve core structures. Field operation data confirms standardized cyclic maintenance can extend the service life of core transmission and hydraulic components by 7500 working hours, effectively reducing unplanned equipment downtime.

On-Site Maintenance Case Studies

Case 1: Daqing Oilfield, ZJ50 Drilling Rig, 30MPa working load. Failed 1200528357 dual safety valve block caused frequent hydraulic overpressure alarms. After replacing the original matching valve assembly, system pressure control accuracy returned to factory standards, with zero overpressure faults during 1200 consecutive working hours. The maintenance team verified greatly improved hydraulic system safety stability.

Case 2: Changqing Oilfield, Workover Rig Supporting System, 26MPa conventional load. Worn external sealing packing led to persistent hydraulic oil leakage. After upgrading matching sealing components, the equipment passed 10-hour static pressure test with zero pressure drop, completely solving field leakage problems.

Case 3: Tarim Oilfield, Well Control Preventer Equipment, 32MPa high load. Abnormal wear of gear shaft caused unsmooth power transmission. After gear shaft replacement, equipment transmission gap was eliminated, and operational noise decreased significantly, meeting standard drilling operation indicators.

Case 4: Shengli Oilfield, Drilling Hoisting System, 28MPa working pressure. Fatigued API 9A pressed rope caused reduced load-bearing capacity. After rope replacement, the hoisting system maintained stable load-bearing performance under rated load, fully meeting field construction safety requirements.
