Every component complies with API 7K drilling equipment safety standards and IEC industrial electrical certification, delivering stable and reliable support for high-intensity continuous drilling operations.

Full Product Introduction

The complete spare parts range includes dosing and variable pump hose lines, SAE standard hydraulic fittings, encoder timing belt gears, top drive air conditioner transformers, mushroom head pushbutton switches, pressure relief valve cartridges, air pressure switches, circlips, brake piston oil seals, multi-core power cable assemblies, NC50 spline IBOP assemblies, gearbox lube pump units, differential pressure switches, Siemens brake chopper modules, thyristor blocks, inverter trigger boards and precision piston ring sets. All core parts adopt original factory precision machining standards, with key hydraulic components maintaining stable pressure bearing capacity up to 35MPa, and electrical components supporting 575V AC high-voltage stable operation. The whole set of accessories achieves 8000 hours of continuous stable service life under rated working conditions, far exceeding ordinary alternative parts in field adaptability and durability.

Core Functional Description

Hydraulic pipeline and valve components stabilize the oil circuit transmission of variable pumps and dosing pumps, eliminate pressure surge during drilling parameter switching, and ensure consistent action of hydraulic actuators. Well control parts such as NC50 spline IBOP assemblies provide reliable downhole blowout prevention and fluid isolation, supporting safe tripping and drilling pause operations. Electrical control modules including brake choppers, thyristor blocks and trigger boards guarantee precise inverter signal control and stable power output of the top drive system. Mechanical transmission and sealing accessories reduce equipment friction loss, prevent medium leakage and maintain accurate synchronous operation of encoder transmission structures.

Structural Characteristics

All spare parts adopt modular integrated structure with unified standard interfaces, enabling fast on-site disassembly and replacement without secondary parameter debugging. Hydraulic fittings adopt 37-degree O-ring boss sealing structure to achieve zero leakage under cyclic pressure changes. Electrical core boards are equipped with anti-electromagnetic interference shielding structure to adapt to complex drilling site electromagnetic environments. Sealing and wearing parts adopt high-strength wear-resistant composite materials, with integrated molding technology to avoid permanent deformation under long-term alternating load. Stainless steel split rings and circlips feature high tensile strength, effectively preventing mechanical loosening during high-vibration operation.

Applicable Working Conditions

These accessories adapt to onshore deep well drilling, offshore platform drilling and workover operation scenarios, matching the 500-ton lifting load and 37500 ft-lb continuous drilling torque of TDS-11SA top drive systems. They stably operate in ambient temperatures ranging from -30℃ to 65℃, and resist high dust, high humidity and slight corrosive field environments. All electrical parts pass strict high-voltage insulation testing, and hydraulic components adapt to long-cycle variable pressure operation of drilling hydraulic systems.

On-Site Maintenance & Engineer Practical Suggestions

Summarized from years of field drilling equipment maintenance experience, practical operation guidelines can effectively reduce equipment failure rates. Replace hydraulic hose lines and sealing gaskets every 400 continuous working hours to avoid aging cracking and oil leakage. Calibrate air pressure switches and differential pressure switches every 250 hours to ensure accurate drilling pressure signal feedback. Regularly inspect inverter fuse and thyristor block status to prevent electrical system short-circuit faults. Avoid excessive torsion during hydraulic elbow installation to prevent thread deformation and pressure loss. Clean dust and oil stains on control and trigger boards monthly to maintain stable signal transmission accuracy.
