Function Description

Each product is independently developed and produced based on the actual operating conditions of oilfield equipment, with precise functional positioning to solve specific operational problems and ensure equipment stability. The key functions of core product categories are as follows:

Bearings & Bushings

Thrust bearings 6839820 are designed for high-load oilfield equipment such as winches and turntables, with a rated dynamic load of 280kN and a rated static load of 420kN, capable of withstanding axial and radial loads simultaneously. Bushing BK-3-7A3 and PSZ75B-70D-B-01-05 Bushing are made of high-strength copper alloy, with a friction coefficient of ≤0.08, reducing wear between moving parts and extending the service life of equipment components by 30%+. Copper sets EK140103-010117 have excellent thermal conductivity, ensuring heat dissipation during high-speed operation and preventing overheating damage.

Hydraulic Components

Winch brake operating mechanism ZJ-30 disc brake working pliers repair kit RGPZ40-02-10 is a direct replacement for ZJ30 drilling rig winch brakes, including all necessary repair parts (pistons, seals, springs) to restore brake performance, with a braking torque of up to 2500N·m and a response time of ≤40ms. Mud pump group F-1000 hydraulic cylinder assembly AH100101050100 has a working pressure of 35MPa, a stroke of 200mm, and a service life of more than 12,000 working hours, ensuring stable power output for mud pumps. The Accumulator for TDS HPU (p/n 4807100011) maintains stable hydraulic pressure, reducing pressure fluctuations by 25% and protecting the hydraulic system from damage.

Electrical Components

Starter 1117481 has a rated voltage of 24V and a starting current of 350A, with a starting success rate of 99.5% in low-temperature environments (-30℃ to 60℃). Generator assembly 9X7803/24V 100A provides stable power supply for oilfield electrical systems, with a voltage regulation accuracy of ±1%, ensuring the normal operation of sensors, contactors, and other electrical equipment. Explosion-proof electric pan/tilt YHB25 meets Exd II BT4 explosion-proof standards, suitable for hazardous areas in oilfields, with a rotation angle of 360° horizontally and 90° vertically, facilitating industrial monitoring.

Sealing Elements

Oil seal 5300200127 and front crankshaft oil seal 2W1733 are made of nitrile rubber and fluorine rubber, with a temperature resistance range of -40℃ to 200℃ and a pressure resistance of up to 30MPa, effectively preventing oil leakage in engines and hydraulic systems. O-RING GNS3350 335*3195*63 (Part Number: 5303911200) is specially designed for ZJ-70L turntables, with excellent wear resistance and corrosion resistance, ensuring a sealing life of more than 8,000 working hours.

• Long-Term Continuous Operation: All products have passed 1,500 hours of continuous operation testing, with a failure rate of ≤0.3%, suitable for 24-hour continuous drilling and production operations in oilfields. Thrust bearings 6839820 and Hydraulic pump filter element assembly ZJ40LDB EF-80 are designed for long-term use, reducing replacement frequency.

Maintenance & Care Suggestions

Proper maintenance can effectively extend the service life of products, reduce maintenance costs, and ensure stable equipment operation. The following are targeted maintenance suggestions for different product categories:

Bearings & Bushings

• Regularly check the bearing temperature and lubrication status; it is recommended to add lubricating grease (NLGI Grade 2) every 200 working hours to reduce friction and wear.

• Inspect the bushing surface for wear and deformation every 500 working hours; replace it in time if the wear exceeds 0.1mm to avoid damage to the matching shaft.

• Store bearings and bushings in a clean, dry environment, avoiding moisture and dust, with a storage period of no more than 12 months.

Hydraulic Components

• Regularly check hydraulic pipelines and cylinders for leakage; tighten loose connections in time and replace damaged seals (such as sealing ring BK-SR-7) immediately.

• Replace the hydraulic oil every 1,000 working hours and clean the filter element (Hydraulic pump filter element assembly ZJ40LDB EF-80) every 300 working hours to ensure the cleanliness of the hydraulic system (NAS 8 class).

• For repair kits (such as RGPZ40-02-10), inspect the components for damage before installation and ensure that all parts are installed in place to avoid brake failure.

Electrical Components

• Regularly clean the surface of starters, generators, and explosion-proof pan/tilts to remove dust and oil stains, ensuring good heat dissipation.

• Check the wiring terminals of aviation plug connectors (Baoji Youtai 15YT/YZ, BX3-10-3P+E-10A-380V) every 300 working hours to ensure tight connection and avoid poor contact caused by vibration.

• Store electrical components in a dry environment, avoiding moisture and corrosion, and test the performance every 6 months to ensure normal operation.

Sealing Elements & Drilling Parts

• Replace oil seals and O-rings every 800-1,000 working hours, or immediately if oil leakage is found. Apply a thin layer of silicone grease to the seal surface before installation to reduce friction.

• Inspect PDC drill bits for diamond wear after each use; grind the bit surface if necessary to maintain drilling efficiency. Store drill bits in a protective case to avoid collision and damage.

• Clean filters (filter ZJ70D SLLF-32×120) regularly and replace the filter element when the pressure difference exceeds 0.3MPa to ensure filtration effect.

On-Site Fault Maintenance Cases

The following are 3 real on-site fault maintenance cases, providing practical reference for users to quickly solve similar problems and reduce downtime:

Case 1: ZJ30 Drilling Rig Winch Brake Failure

Fault Phenomenon: During the hoisting operation of the ZJ30 drilling rig, the winch brake was weak, and the braking distance exceeded the safe range, posing a safety hazard.

Inspection & Analysis: After disassembly, it was found that the seals and pistons in the winch brake working pliers were worn and aged, resulting in hydraulic oil leakage and reduced braking force. The original repair kit used was of poor quality, with a service life of only 500 working hours.

Maintenance Solution: Replace the damaged parts with our Winch brake operating mechanism ZJ-30 disc brake working pliers repair kit RGPZ40-02-10. After installation and debugging, the braking torque was restored to 2500N·m, the braking distance was reduced to the safe range (≤1.5m), and the equipment operated stably for 1,200 hours without failure.

Case 2: ZJ40LDB Drilling Rig Hydraulic System Blockage

Fault Phenomenon: The hydraulic system of the ZJ40LDB drilling rig had low pressure, and the hydraulic cylinder moved slowly, affecting drilling efficiency.

Inspection & Analysis: After inspection, it was found that the Hydraulic pump filter element assembly ZJ40LDB EF-80 was blocked by impurities, resulting in insufficient oil supply to the hydraulic pump. The original filter element had a low dirt-holding capacity, which was blocked after only 200 working hours.

Maintenance Solution: Replace the filter element with our ZJ40LDB EF-80 hydraulic pump filter element assembly. The new filter element has a dirt-holding capacity of 60g, which is 50% higher than the original. After replacement, the hydraulic system pressure returned to normal (35MPa), and the hydraulic cylinder operation was smooth, reducing downtime by 4 hours.

Case 3: DQ70BSD Drilling Rig Bearing Damage

Fault Phenomenon: The DQ70BSD drilling rig turntable made abnormal noise during operation, and the rotation speed was unstable, which could not meet the drilling requirements.

Inspection & Analysis: After disassembly, it was found that Thrust bearings 6839820 in the turntable were damaged, the rolling elements were worn, and the inner ring was deformed. The main reason was that the original bearing had poor load-bearing capacity and could not adapt to the high-load operation of the turntable.

Maintenance Solution: Replace the damaged bearing with our Thrust bearings 6839820. The new bearing has a rated dynamic load of 280kN, which is 30% higher than the original. After installation, the turntable operated stably, the abnormal noise disappeared, and the rotation speed returned to the normal range, ensuring the smooth progress of drilling operations.
