Maintenance & Care Suggestions

To extend the service life of the parts and ensure the long-term stable operation of the equipment, we formulate the following maintenance and care suggestions according to API 7K and GB/T 12224-2015 standards, combined with the actual working conditions of the parts:

1. Regular Inspection: Conduct a comprehensive inspection of key parts every 400 working hours, focusing on checking the wear, deformation and sealing performance of bearings, sealing rings, valve cores and other parts. Replace parts that have reached the wear limit (such as O-rings with cracks, bearings with wear exceeding 0.1mm) in time.

2. Lubrication Maintenance: Add lubricating oil (recommended model: ISO VG 68 hydraulic oil) to moving parts (winch drive shaft, crosshead bearing, steering gear) every 150 working hours, ensuring sufficient lubrication, reducing friction wear, and improving the service life of parts by 30%.

3. Cleaning Maintenance: Clean filter elements (3831236, 4N0015 05B 02G 02-306) and air filters (C125004) every 250 working hours, and replace them every 900 working hours to prevent impurities from entering the equipment system and causing wear or blockage.

4. Storage Conditions: Unused parts should be stored in a dry, ventilated and clean warehouse, avoiding direct sunlight, moisture and corrosion. Sealing parts should be stored in sealed containers to prevent aging and deformation. The storage temperature should be controlled between -15℃ and 35℃, and the relative humidity should not exceed 55%.

5. Installation & Use 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 (bolt 179850, spring washer 420503016201600000), apply torque according to the specified value (recommended torque: 320N·m) to prevent looseness or damage. For boiler parts, check the sealing performance before use to avoid leakage.

On-Site Fault Maintenance Cases

The following are 3 real on-site fault maintenance cases, which provide practical reference for users to solve common faults of drilling rigs, boilers and supporting equipment parts, and all cases are verified by on-site maintenance records:

Case 1: Hydraulic Oil Leakage of ZJ50 Drilling Rig Hydraulic System

Fault Phenomenon: During the operation of the ZJ50 drilling rig, hydraulic oil leakage occurred at the hydraulic cylinder connection, resulting in reduced system pressure and unstable operation of the drilling rig. After inspection, it was found that the original sealing ring was aged and deformed, and the sealing performance was lost.

Solution: Replace the original sealing ring with ODtype Sealing Ring ZJ50 PSZ75 OD080005200171D, which is perfectly matched with the ZJ50 drilling rig hydraulic cylinder. After installation, the hydraulic oil leakage is completely eliminated, the system pressure is restored to the normal range (21MPa), and the drilling rig operates stably. The maintenance effect is verified by 1000 working hours of continuous operation.

Case 2: Boiler Water Level Monitoring Failure of WNS1-1.25 Boiler

Fault Phenomenon: The WNS1-1.25 industrial boiler had a water level gauge failure during operation, and the water level display was inaccurate, which posed a safety hazard of dry burning. After inspection, it was found that the original sensor type water level gauge was damaged, and the measurement accuracy could not meet the requirements.

Solution: Replace the water level gauge with Boiler WNS1-1.25 Sensor Type Water Level Gauge C1.6-HB350, which is compatible with WNS1-1.25 boilers. After installation, the water level display is accurate, the measurement error is within ±1.6%, and the real-time water level signal is transmitted normally, eliminating the safety hazard and ensuring the safe operation of the boiler.

Case 3: Steering Jamming of ZJ40 Drilling Rig

Fault Phenomenon: The ZJ40 drilling rig had steering jamming during operation, and the steering was inflexible, affecting the drilling efficiency. After inspection, it was found that the steering gear V10-1P7P-038D-20L was worn, and the internal bearing was damaged, resulting in increased friction.

Solution: Replace the steering gear with a new ZJ40 steering gear V10-1P7P-038D-20L, and add lubricating oil according to the maintenance requirements. After replacement, the steering of the drilling rig is smooth and flexible, the friction coefficient is reduced to ≤0.025, and the steering efficiency is improved by 25%.
