Function Description

Key Component Functions

• Slurry Pump Impellers (F6147, D3021, G8147U38): Responsible for conveying drilling fluid (slurry) in the drilling process, with strong wear resistance and corrosion resistance, ensuring stable fluid flow and pressure, and avoiding blockage or damage caused by high-concentration slurry.

• One-way Clutches (ZJ-30C, ZJ-40) & One-way Valves (I-100/4900300007): Prevent reverse rotation of equipment components and backflow of fluids, protect the transmission system and pipeline safety, and ensure the one-way operation of the drilling rig and hydraulic system.

• Encoder Assemblies (ZJ70 9702013000) & Inclinometers (YST-48R, GE-MWD): Real-time collect and transmit drilling parameters (such as rotation speed, inclination angle) to the control system, helping operators adjust drilling posture and depth accurately, ensuring drilling precision and safety.

• Filter Elements (ZJ32L PSZ65 FAX-63×10, 23518481) & Filter Pressure Reducing Valves (В030000337): Filter impurities in hydraulic oil, lubricating oil, and other media, reduce component wear, stabilize system pressure, and extend the service life of hydraulic and transmission systems.

• Brake System Components (Breather Valve KG-75-02, Electromagnetic Eddy Current Brake ZJ30C, Clutch Torsion Bar 700*135): Ensure the safe braking of the drilling rig, control the speed of the drill string and hoist, and avoid accidents caused by brake failure.

Structural Features

Overall Structural Advantages

All our spare parts adopt a precision manufacturing process, with the following structural features to meet the harsh working environment of oil drilling:

• High-Strength Material Selection: Key components (such as impellers, shafts, gear hubs) are made of high-quality alloy steel, wear-resistant cast iron, or corrosion-resistant materials, with high tensile strength, impact resistance, and corrosion resistance, adapting to high-temperature, high-pressure, and high-dust drilling environments.

• Precision Machining: Adopt CNC machining technology, with strict control of dimensional accuracy (tolerance ≤ ±0.01mm), ensuring perfect matching with original equipment, no assembly gaps, and avoiding vibration and noise during operation.

• Sealing and Shockproof Design: Sealing components (such as spring seals ZJ32 D7-1-67 150×180, O-rings 9M2008) adopt multi-layer sealing structures, effectively preventing oil leakage, water leakage, and dust entry; shockproof components (such as shockproof pressure gauges FKQ640-7 Y100ZT-25MPa) are equipped with damping structures to reduce the impact of drilling vibration on component accuracy.

• Modular Design: Most components (such as control systems, connectors) adopt a modular structure, which is easy to disassemble, assemble, and replace, reducing maintenance time and labor costs.

Applicable Working Conditions

Our drilling spare parts are widely applicable to various oil drilling scenarios, including but not limited to:

• Onshore Oilfield Drilling: Suitable for ZJ25-ZJ70 series drilling rigs, adapting to different geological conditions (such as sandstone, shale, limestone), and working stably under high temperature (≤ 80℃) and high pressure (≤ 25MPa).

• Slurry Pump Operation: F6147, D3021, G8147U38 impellers and other slurry pump parts are suitable for conveying high-concentration, high-abrasion drilling fluid, applicable to both vertical and horizontal drilling operations.

• Harsh Environment Operations: Components such as corrosion-resistant filter elements, sealed connectors, and shockproof pressure gauges can adapt to humid, dusty, and corrosive working environments (such as coastal oilfields, desert oilfields).

• Equipment Maintenance and Emergency Repair: All spare parts are designed to be interchangeable with original equipment, suitable for on-site emergency repair and daily maintenance of drilling rigs, slurry pumps, top drives, and other equipment.

Maintenance and Care Suggestions

Daily Maintenance Guidelines

• Regular Inspection: Check the wear status of key components (such as impellers, brake shoes, filter elements) every 100 hours of operation; check the tightness of connectors (such as straight connectors ZJ50 2-M14×1.5, high-pressure connectors 1/4″ AH33002-07) and the sealing performance of seals to avoid oil leakage or loosening.

• Cleaning and Replacement: Clean filter elements every 200 hours of operation, and replace them in time when the pressure difference exceeds 0.5MPa; clean the surface of impellers and pipeline components regularly to remove slurry deposits and avoid blockage.

• Lubrication Maintenance: Apply lubricating oil to rotating components (such as one-way clutches, gear hubs) regularly, choose lubricating oil that meets API standards, and ensure sufficient lubrication to reduce friction and wear.

• Storage Requirements: Store spare parts in a dry, ventilated, and dust-free warehouse, avoid direct sunlight and moisture; for precision components (such as encoder assemblies, inclinometers), store them in shockproof packaging to prevent damage to internal electronic components.

Precautions for Replacement

When replacing spare parts, please strictly follow the original equipment operation manual, and pay attention to the following points:

• Ensure that the model and specification of the replacement part are completely consistent with the original part (such as checking the part number: 5495500 for 5’’ LINER, 36001-0415 for SEAL GASKET) to avoid assembly failure.

• Before installation, clean the installation position of the part to remove impurities and debris, and check whether the installation surface is flat.

• For electronic components (such as encoders, sensors), cut off the power supply before replacement to avoid short circuits or damage to the control system.

• After installation, conduct a test run to check whether the part operates normally, and adjust the parameters if necessary to ensure that it meets the working requirements.

On-Site Fault Repair Cases

The following are 3 real on-site fault repair cases, which can help you quickly locate and solve similar problems by using our spare parts:

Case 1: Slurry Pump Impeller Wear Leading to Reduced Pump Efficiency

Site: An onshore oilfield ZJ70D drilling rig slurry pump (model F6147)
Fault Phenomenon: The pump output flow is significantly reduced, the pump body vibrates violently, and there is abnormal noise.
Inspection Result: The F6147 slurry pump impeller is severely worn, the blade surface is damaged, and the internal flow channel is blocked by slurry deposits.
Repair Solution: Replace the worn F6147 impeller with our high-wear-resistant F6147 slurry pump impeller, clean the pump body and pipeline, and re-adjust the pump pressure.
Effect After Repair: The pump output flow returns to normal, the vibration and noise are eliminated, and the pump efficiency is restored to 95% or more, ensuring the normal progress of drilling operations.

Case 2: One-Way Clutch Failure Causing Drill String Reverse Rotation

Site: A ZJ30C drilling rig hoisting system
Fault Phenomenon: During the hoisting process, the drill string reverses suddenly, and the hoist cannot maintain a stable position.
Inspection Result: The ZJ-30C one-way clutch is damaged, the internal bearing is stuck, and the one-way transmission function fails.
Repair Solution: Replace the damaged one-way clutch with our ZJ-30C one-way clutch, check the transmission system, and lubricate the related components.
