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 brake components, transmission shafts, hydraulic valves, sealing parts, and electrical modules, 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 filter elements, temperature probes, and lithium batteries, check for wear and damage every 200 working hours.

2. Cleaning & Replacement: Clean the surface of hydraulic filters (TFX-63×80) every 50 working hours, and replace the filter element every 500 working hours; clean the turntable drive shaft, friction disc, and throat lining every 800 working hours to remove sediment and impurities, ensuring smooth operation.

3. Lubrication Maintenance: Apply No. 32 anti-wear hydraulic oil or special lubricating grease to transmission parts (turntable drive shafts, cross heads, gears) every 200 working hours, and apply grease to pins, connectors, and valve stems 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 lithium batteries, store them in sealed packaging to avoid aging; for electrical parts and explosion-proof devices, 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; for boiler and electrical parts, ensure correct wiring and grounding. 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 industrial equipment 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: ZJ70D Drilling Rig Pressure Transmitter Failure

Fault Phenomenon: During the operation of the ZJ70D drilling rig, the BSCYG9010-1.0 explosion-proof pressure transmitter failed to transmit data, leading to inability to monitor the hydraulic system pressure and potential safety risks.

Fault Cause: The transmitter’s mating connector was loose due to strong vibration during drilling, resulting in poor contact and data transmission failure.

Maintenance Solution: Replace the transmitter and its mating connector with our ZJ70D BSCYG9010-1.0 spare parts, rewire and fix the connector tightly, and test the data transmission. After replacement, the pressure transmitter works normally, and the hydraulic system pressure is monitored in real time.

Case 2: WNS1.0-1.25-YQ Boiler Temperature Monitoring Failure

Fault Phenomenon: The WNS1.0-1.25-YQ boiler’s WRN 218 flue temperature probe failed, resulting in inability to monitor flue temperature, unstable boiler combustion, and failure to meet production safety standards.

Fault Cause: The probe’s sensing element was damaged due to long-term exposure to high-temperature flue gas, leading to measurement failure.

Maintenance Solution: Replace the flue temperature probe with our WRN 218 spare part, install it correctly and seal it tightly, and debug the boiler control system. After replacement, the flue temperature is monitored normally, the boiler combustion is stable, and production resumes safely.

Case 3: ZJ-40 Turntable Drive Shaft Oil Leakage

Fault Phenomenon: The ZJ-40 turntable drive shaft’s PG150.180.16 double lip oil seal leaked, resulting in reduced lubricating oil level, increased friction of the drive shaft, and abnormal noise during operation.

Fault Cause: The oil seal was worn after 5000 working hours of use, and the sealing performance decreased, leading to oil leakage.

Maintenance Solution: Replace the oil seal with our PG150.180.16 spare part, add lubricating oil to the standard level, and test the turntable operation. After replacement, there is no oil leakage, the abnormal noise disappears, and the turntable operates normally.
