Maintenance & Care Suggestions

To extend the service life of the products, reduce equipment failure rate, and ensure the stable operation of the entire equipment system, we provide the following professional maintenance and care suggestions, which are practical and easy to operate, and can help users reduce maintenance costs and improve equipment utilization:

1. Regular Inspection: For brake system parts, hydraulic hoses, and sealing parts, conduct a comprehensive inspection every 100 working hours, check for wear, cracks, deformation, and leakage, and replace them in time if any abnormality is found; for electrical parts, check the circuit connection and insulation performance every 200 working hours to avoid short circuit.

2. Cleaning & Replacement: Clean the surface of filters (air filter QAF-4000-04, oil filter 1R0716) every 50 working hours, and replace the filter element every 500 working hours; clean the impeller and volute liner of the pump every 800 working hours to remove sediment and impurities, ensuring smooth flow.

3. Lubrication Maintenance: Apply lubricating oil (No. 32 anti-wear hydraulic oil) to transmission parts (intermediate shaft, connecting rod) every 200 working hours, and apply grease to bearings (4500100326) every 300 working hours to reduce friction and wear, extending the service life of the parts.

4. Storage Requirements: Unused spare parts should be stored in a dry, ventilated, and clean warehouse, avoiding direct sunlight, rain, and contact with corrosive substances; the storage temperature should be controlled between -10℃ and 40℃, and the relative humidity should not exceed 75%; for sealing parts, store them in sealed packaging to avoid aging.

5. Installation & Fault Handling: When installing the parts, ensure that the connection is tight, and the torque meets the standard (refer to the original equipment manual); do not use damaged or unqualified parts. If the parts fail during use, stop the equipment immediately, check the cause of the fault according to the maintenance manual, and do not force the equipment to operate to avoid secondary damage to the equipment.

On-Site Fault Maintenance Cases

We have accumulated rich on-site maintenance experience in long-term cooperation with oilfield, boiler, and mining enterprises. The following are 3 real on-site fault maintenance cases, which can provide practical reference for users to solve similar technical problems and ensure the rapid recovery of equipment operation:

Case 1: ZJ-70 Drilling Rig Hydraulic System Pressure Instability

Fault Phenomenon: During the drilling process of the ZJ-70 drilling rig, the hydraulic system pressure fluctuated greatly (25MPa ~ 32MPa), resulting in unstable operation of the drill bit and affecting drilling efficiency.

Fault Cause: After on-site inspection, the filter regulator (512605510020150000) was blocked by impurities, the internal valve core was worn, and the pressure regulation function failed, leading to unstable system pressure.

Maintenance Solution: Replace the filter regulator with our 512605510020150000 spare part, clean the hydraulic oil pipeline, and test the system pressure. After replacement, the hydraulic system pressure is stable at 30MPa ±0.5MPa, the drill bit operates normally, and the drilling efficiency is restored to the normal level.

Case 2: WNS2-1.0-Y(Q) Boiler Level Indicator Failure

Fault Phenomenon: The WNS2-1.0-Y(Q) industrial boiler’s magnetic float level gauge (UDZ-300PPCE) failed, the liquid level display was inaccurate, and the boiler could not adjust the water supply normally, posing a safety hazard.

Fault Cause: The float of the magnetic float level gauge was stuck due to scale accumulation, and the internal magnetic induction element was aging, resulting in inaccurate liquid level display.

Maintenance Solution: Replace the magnetic float level gauge with our UDZ-300PPCE spare part, clean the boiler water tank to remove scale, and calibrate the liquid level display. After replacement, the liquid level display accuracy is ±1mm, the boiler water supply is adjusted normally, and the safety hazard is eliminated.

Case 3: DQ70BS Drilling Rig Brake Failure

Fault Phenomenon: The DQ70BS drilling rig’s brake system failed during operation, the brake could not be locked, and the drill string could not be fixed, which seriously affected the safety of the operation.

Fault Cause: The brake shoe bolt (ZJ70DB M12×30) was loosened and worn, and the friction plate (29537887) was severely worn, resulting in insufficient braking force.

Maintenance Solution: Replace the brake shoe bolt (ZJ70DB M12×30) and friction plate (29537887) with our spare parts, adjust the brake clearance, and test the braking performance. After replacement, the braking torque reaches 12000N·m, the brake locks firmly, and the drilling rig resumes safe operation.
