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 practical, easy-to-operate maintenance and care suggestions, helping users reduce maintenance costs and improve equipment utilization:

1. Regular Inspection: For hydraulic valves, sealing parts, brake components, and belts, 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 drilling bits and pump parts, check for wear and damage every 200 working hours.

2. Cleaning & Replacement: Clean the surface of filters (1R0753 filter element, ZJ30C FRA-160XL-C filter element) every 50 working hours, and replace the filter element every 500 working hours; clean the volute liner and drill bit every 800 working hours to remove sediment and impurities, ensuring smooth operation.

3. Lubrication Maintenance: Apply lubricating oil (No. 32 anti-wear hydraulic oil) to transmission parts (winch drive shaft, chain) every 200 working hours, and apply grease to bearing bushes and bearings (32622H GB283-87) 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 and O-rings, store them in sealed packaging to avoid aging; for electrical parts, keep them away from moisture and dust.

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); for hydraulic and pneumatic parts, check for air leakage before operation. 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.

On-Site Fault Maintenance Cases

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

Case 1: ZJ40LDB Drilling Rig Hydraulic Plunger Pump Failure

Fault Phenomenon: During the operation of the ZJ40LDB drilling rig, the hydraulic plunger pump (80YCY14-1B) made abnormal noise, and the hydraulic system pressure fluctuated greatly (25MPa ~ 30MPa), affecting the drilling efficiency.

Fault Cause: The pump’s internal cylinder liner was severely worn after 7500 working hours of use, and the plunger seal was damaged, leading to pressure leakage and abnormal noise.

Maintenance Solution: Replace the hydraulic plunger pump with our ZJ40LDB 80YCY14-1B spare part, and replace the cylinder liner (1979322) and plunger seal. After replacement, the hydraulic system pressure is stable at 28MPa, the abnormal noise disappears, and the drilling rig operates normally.

Case 2: ZJ30C Drilling Rig Brake System Failure

Fault Phenomenon: The ZJ30C drilling rig’s brake system responded slowly during operation, and the braking force was insufficient, posing a safety hazard during hoisting operations.

Fault Cause: The hydraulic oil tank return oil filter element (FRA-160XL-C) was blocked by impurities, leading to poor oil circulation and insufficient brake pressure.

Maintenance Solution: Replace the filter element with our ZJ30C FRA-160XL-C spare part, clean the hydraulic oil pipeline, and add new hydraulic oil. After replacement, the brake response time is reduced to ≤0.4 seconds, the braking force is restored to the standard level, and the safety hazard is eliminated.

Case 3: WNS2-1.25-Y Boiler Pump Motor Failure

Fault Phenomenon: The WNS2-1.25-Y boiler’s pump motor (Y2A80M2-2 380V/1) failed to start, resulting in no water supply to the boiler and forced shutdown of industrial production.

Fault Cause: The motor’s internal winding was burned due to long-term overload operation, leading to failure to start.

Maintenance Solution: Replace the pump motor with our WNS2-1.25-Y Y2A80M2-2 380V/1 spare part, check the power supply and circuit, and test the motor operation. After replacement, the motor starts normally, the boiler water supply is restored, and industrial production resumes.
