Product Introduction

Core Product Category & Adaptable Equipment

Our spare parts cover multiple types of oilfield equipment, with clear adaptation to models, solving the problem that customers cannot find matching parts quickly. The key adaptable equipment and corresponding core parts are as follows:

• ZQ203 Series Equipment: Shifting Fork 01.01.01-02M model ZQ203-100, Roller 100 01.01-11 (ZQ203-062), mainly used for transmission systems of oilfield drilling equipment, solving the problem of transmission jamming caused by worn forks and rollers.

• Gardner Denver PZ-7 Pump: Lock cover 2011857, a key component of the pump fluid end, preventing fluid leakage and ensuring stable pump operation.

• NOV TDS-10SH Top Drive: Running skirt section of clamp from cylinder side (p/n: 122019), adapting to the top drive’s 250-ton hoisting capacity and 400HP drilling power, ensuring safe clamping of drill pipes during high-load operation.

• ZJ40 Drilling Rig (Four-machine factory): Brake pads P6042918AA, matching the rig’s braking system, solving the problem of reduced braking efficiency caused by worn pads.

• Other Equipment: JC70 Brake system hydraulic station, JC50 DBSY-II, Secondary bridge 5001000151 SJ Petro, and various pumps, motors, and transmission equipment, with corresponding seals, bearings, fasteners, and electrical components.

Function Description

Each spare part is designed for specific functions, targeting the core needs of equipment operation and solving practical pain points on site:

• Transmission Components (Shifting Fork, Roller, Spline Coupling): Ensure smooth power transmission, reduce friction loss, and avoid transmission failure. For example, the ZQ203-100 shifting fork is made of high-strength alloy steel, which can withstand a maximum torque of 30,000 N·m, solving the problem of fork breakage during high-load transmission.

• Sealing Components (O-RING, Oil Seal, Mechanical Seal): Prevent leakage of oil, gas, and fluid media, protect internal components from corrosion and contamination. The Mechanical seal SСM-G0006013 complies with API 682 standard, with a leakage rate of less than 5ml/h, solving the problem of serious leakage of traditional seals in high-pressure environments.

• Braking Components (Brake Pads, Hydraulic Station): Ensure reliable braking of equipment, avoid safety accidents caused by braking failure. The JC70 Brake system hydraulic station provides stable hydraulic pressure up to 15MPa, ensuring sensitive braking even in low-temperature environments.

• Electrical Components (Relay, Fuse, Output Indicator Module): Ensure stable operation of the equipment’s electrical system, avoid short circuits and equipment shutdown. The Bartec Output indicator module (140244-2) can accurately display torque and speed data, with an error of less than ±1%, helping operators monitor equipment status in real time.

Structural Features

Our spare parts adopt advanced structural design and high-quality materials, with obvious advantages in durability and adaptability:

• High-Strength Material Selection: Most mechanical components are made of 40Cr alloy steel and polyurethane, with high hardness (HRC 45-50) and wear resistance. For example, the brake pads P6042918AA use ceramic-based composite materials, which can withstand high temperatures up to 600℃ without deformation.

• Precision Machining: All parts are processed by CNC machine tools with a machining accuracy of ±0.01mm, ensuring tight fit with the original equipment, avoiding installation difficulties caused by size deviation. The O-ring 105×3.1 GB1253-76 adopts a special cross-sectional design, improving sealing performance by 30% compared with ordinary O-rings.

• Corrosion and High-Temperature Resistance: Sealing components such as the 5300200661 HG4-692 oil seal are made of nitrile rubber, which can resist corrosion of crude oil, water, and chemical media, and adapt to working temperatures from -40℃ to 120℃, suitable for harsh oilfield environments.

• Easy Installation: The structural design is optimized according to on-site operation needs, such as the Packing device assembly SL001.05.00, which can be installed without professional special tools, reducing installation time by 40%.

Applicable Working Conditions

Our spare parts are widely applicable to various harsh oilfield working conditions, solving the problem of poor adaptability of ordinary parts:

• Onshore and Offshore Drilling Platforms: Adapt to high humidity, high salt spray, and strong wind environments, such as the mud umbrella 240×167×10 SL225-24, which can effectively prevent mud and seawater from corroding equipment components.

• High-Pressure and High-Temperature Oil Wells: Suitable for oil wells with downhole pressure up to 15,000 psi and temperature up to 200℃, such as the SEAL, IMPELLER, 648405082 19110-72, which can maintain stable sealing performance under high pressure and high temperature.

• Low-Temperature Frozen Oilfields: Adapt to working temperatures as low as -40℃, such as the Air tube clutch (RPD) LT 500/250, which can start normally without jamming in low-temperature environments.

• High-Dust and High-Impact Environments: Such as open-pit oilfields and desert oilfields, the FLAT TYPE SCREEN PWP 500 HP-A140 can effectively filter dust and impurities, preventing equipment wear and blockage.

Maintenance and Care Suggestions

Based on years of on-site maintenance experience, our engineers provide practical maintenance suggestions to extend the service life of spare parts and reduce maintenance costs (engineer’s practical advice and pit avoidance reminders):

• Sealing Components: Check the O-rings and oil seals every 3 months. If cracks, aging, or deformation are found, replace them in time. Avoid using sharp tools when installing to prevent damage to the seal lip; apply a thin layer of lubricating oil before installation to reduce friction.

• Mechanical Components (Shifting Fork, Roller): Regularly add lubricating grease (recommended to use No. 2 lithium-based grease) every 6 months, and check the wear status. If the wear amount exceeds 0.5mm, replace it immediately to avoid secondary damage to the transmission system.

• Electrical Components: Keep the relay and fuse dry and clean, avoid water and dust intrusion. Check the wiring terminals every 4 months to prevent loose connections and short circuits. Do not replace the fuse with a model that does not match the specifications, otherwise it may cause equipment burnout.

• Storage Requirements: Store spare parts in a dry, ventilated warehouse with a temperature of 5-25℃ and a humidity of less than 60%. Avoid direct sunlight and contact with corrosive media. For long-term stored seals, place them in a sealed container to prevent aging.
