Detailed Product Description
Product Introduction
This series covers all listed oilfield critical components, from the5000701021 transmission shaft as the core power transmission component, to ZQ203 series jaw assemblies, rollers, rubber sleeves, TDS-10SH special piston seals, adjusting shims, Honghua ZP375 rotary table input shaft assemblies, and various hydraulic valves, sealing kits, fasteners and sensors. All products are produced with raw materials sourced from certified steel mills and polymer material suppliers, adopting precision forging, precision machining, and high-temperature vulcanization processes, fully fitting the installation size and working parameters of original supporting equipment, without modification or secondary processing during installation. Whether it is a small fastening screw, sealing ring, or large-scale shafting, brake assembly, and gear housing, all parts are positioned as high-reliability replacement parts for long-term drilling field operations, solving the pain points of difficult procurement of original parts, long waiting cycles, and high costs for global drilling teams.
Function Description
Each component undertakes irreplaceable functional tasks in the drilling equipment system: the transmission shaft and shaft coupling complete power transmission between drilling equipment components, ensuring stable torque output; sealing glands, mechanical seals VJ56, and packing seal kits prevent hydraulic oil, drilling fluid, and gas leakage, meeting oilfield environmental protection and safe production requirements; piston assemblies and impellers drive the normal operation of mud pumps and spray pumps, ensuring smooth circulation of drilling fluid; hydraulic control valves (flow control valve 5126000500, balance valve 5126000581, BK-F-G2 global valve) adjust system pressure and flow direction, guaranteeing precise action of hydraulic actuators; friction discs and brake assemblies complete drawworks braking and clutch engagement, ensuring safe lifting and lowering of drilling tools; wear plates, rollers, and copper bushings reduce component friction loss under heavy load; sensors and thermal relays realize real-time monitoring and overload protection of equipment operating parameters; fasteners and circlips maintain stable connection of equipment components under high-frequency vibration working conditions.
Structural Features
All components adopt structural designs tailored to oilfield extreme working conditions: rotating shafts use integral forging blank structure with refined surface finish, eliminating internal stress and avoiding bending deformation under heavy torque; slotted DT11361 ring adopts precision slot machining technology, ensuring tight fit with matching parts and preventing radial movement; rubber sleeves and sealing parts use composite wear-resistant materials, with built-in metal reinforcement layer to withstand high-pressure fluid impact; heavy-duty friction discs use dual-layer friction material bonding structure, uniform stress distribution and strong high-temperature resistance; jaw assemblies and cross supports adopt precision CNC machining, with dimensional tolerance controlled within 0.02mm to ensure perfect fit; wear compensation plates adopt high-hardness alloy material, with uniform thickness and strong impact resistance; hydraulic valve bodies adopt integral forging structure, no welding gaps, avoiding pressure leakage under high working pressure.
Applicable Working Conditions
These spare parts are suitable for harsh working conditions of conventional onshore drilling, desert drilling, and offshore platform drilling, adapting to a temperature range of -45℃ to 220℃, working pressure up to 7500PSI, and stable operation in environments with high sand content, high salinity, high humidity, and continuous mechanical vibration. They are widely applicable to TZJ-30T drilling rigs, NOV TDS-10SH top drive systems, Honghua ZP 375 rotary tables, BPM accumulator units, EATON drawworks clutches, P50 series mud pumps, and various power tongs, mud circulation systems, and hydraulic control systems. They fully meet the working requirements of heavy-load, long-cycle, uninterrupted drilling operations, and are also suitable for daily maintenance, emergency repair, and equipment overhaul of drilling equipment.
Maintenance & Care Suggestions
To extend the service life of components and ensure operational safety, follow these field engineer-verified maintenance tips: 1. Regularly inspect rotating shafts, couplings and friction discs every 30 operating days, check for surface wear, cracks and torque transmission abnormalities, and replace worn parts in time; 2. For sealing components (sealing glands, mechanical seals, packing kits), check for fluid leakage every 15 days, replace sealing kits regularly according to operating hours, and avoid using damaged seals; 3. Clean mud return flow sensors SZJ-HL1.1 every 20 days to remove surface mud attachments, ensuring accurate monitoring data; 4. For fasteners, retorque hex bolts and cap screws according to standard torque values every 45 days to prevent loosening caused by vibration; 5. Lubricate jaw assemblies, rollers and copper bushings regularly with special oilfield high-temperature lubricating grease, avoiding dry friction; 6. Store spare parts in a dry, ventilated and dust-free environment, prevent corrosion and deformation of precision components; 7. For hydraulic components, keep the fluid clean, replace the fluid regularly and install filter elements to avoid particle wear on valve cores and pistons. Engineer Avoidance Tip: Do not mix and match non-original compatible parts of different models, so as not to cause component damage or system failure.
