Maintenance & Care Suggestions

To extend the service life of the parts and ensure the stable operation of the equipment, we recommend the following maintenance and care measures, which are formulated according to API 7K maintenance standards and combined with the actual working conditions of the parts:

1. Regular Inspection: Conduct a comprehensive inspection of key parts every 500 working hours, focusing on checking the wear, deformation and sealing performance of parts such as friction discs, sealing rings, and valve cores. Replace parts that have reached the wear limit (such as friction discs with wear thickness ≥2mm) in time.

2. Lubrication Maintenance: Add lubricating oil (recommended model: ISO VG 46 hydraulic oil) to the moving parts (such as winch drive shafts, rotary joints) every 200 working hours, ensuring that the lubrication is sufficient and reducing friction wear. For lubricators (ZJ50D XJFH-5/35KES QYW-L40-whl), check the oil level regularly and supplement lubricating oil in time.

3. Cleaning Maintenance: Clean the filter elements (oil suction filter element ZJ70D IX-63×180, diesel filter BEZK183/H 12 110/2) every 300 working hours, and replace the filter elements every 1000 working hours to prevent impurities from entering the equipment system and causing wear or blockage.

4. Storage Conditions: For unused parts, store them in a dry, ventilated and clean warehouse, avoid direct sunlight, moisture and corrosion. Sealing parts should be stored in a sealed container to prevent aging and deformation. The storage temperature should be controlled between -10℃ and 30℃, and the relative humidity should not exceed 60%.

5. Installation Precautions: When installing parts, ensure that the installation surface is clean and free of impurities, and use professional tools to avoid violent installation. For fasteners (such as bolt M24X60, T52-7008K), torque should be applied according to the specified value (recommended torque: 350N·m) to prevent loose or excessive torque from damaging the parts.

On-Site Fault Maintenance Cases

The following are 3 real on-site fault maintenance cases, which can provide practical reference for users to solve common problems of drilling equipment parts:

Case 1: Winch Rope Deviation Fault of ZJ50 Drilling Rig

Fault Phenomenon: During the lifting operation of the ZJ50 drilling rig winch, the rope deviated seriously, resulting in rope wear and unstable lifting. After inspection, it was found that the original rope guide was worn and deformed, and the guide range could not meet the requirements of 21mm-27mm.

Solution: Replace the original rope guide with Pneumatic Winch Rope Guide YS-Ⅱa (21mm-27mm), which is perfectly matched with the ZJ50 winch. After installation, the rope runs stably without deviation, and the rope wear rate is reduced by 40%. The fault is completely solved, and the winch operation efficiency is improved.

Case 2: Hydraulic Oil Leakage of ZJ45 Drilling Rig Plunger Pump

Fault Phenomenon: The ZJ45 drilling rig plunger pump PVQ13A2R had serious hydraulic oil leakage at the cylinder liner seal during operation, resulting in reduced system pressure and affecting drilling efficiency. After inspection, it was found that the original cylinder liner seal was aged and damaged, and the sealing performance was lost.

Solution: Replace the cylinder liner seal with AH1602010116B6 cylinder liner seal, which is made of high-quality nitrile rubber, with good oil resistance and sealing performance. After installation, the hydraulic oil leakage is completely eliminated, the system pressure is restored to the normal range (31.5MPa), and the plunger pump runs stably.

Case 3: Braking Failure of ZJ30C Drilling Rig Winch

Fault Phenomenon: The ZJ30C drilling rig winch braking device failed during operation, and the braking force was insufficient, which posed a safety hazard. After inspection, it was found that the friction disc W18-07-904 was severely worn, and the wear thickness exceeded 2mm, which could not provide sufficient braking torque.

Solution: Replace the friction disc with a new W18-07-904 friction disc, which is made of high-temperature resistant and wear-resistant material. After replacement, the braking torque of the winch is restored to 1800N·m, the braking effect is stable, and the safety of the winch operation is guaranteed.
