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 (disc brake blocks, clutches, normally closed brakes), hydraulic valves, sealing parts, and transmission shafts, 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 drill bits, plunger assemblies, and filter elements, check for wear and damage every 200 working hours.

2. Cleaning & Replacement: Clean the surface of filters (Y/G10II-3500 pump high-pressure filter, HDX-40*20 filter, Y/L0003 air filter) every 50 working hours, and replace the filter element every 500 working hours; clean the rig chain, cardan shaft, and gear parts every 800 working hours to remove sediment and impurities, ensuring smooth operation.

3. Lubrication Maintenance: Apply Sullair 250025-669 motor oil or No. 32 anti-wear hydraulic oil to transmission parts (cardan shafts, bearings, clutches) every 200 working hours, and apply grease to bushings, guide wheels, and plungers 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 explosion-proof electrical parts and solid state relay boards, 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 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, TDS, 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: ZJ50 Drilling Rig Cardan Shaft Failure

Fault Phenomenon: During the operation of the ZJ50 drilling rig, the W60.5×735 cardan shaft made abnormal noise, and the power transmission was unstable, leading to reduced drilling efficiency and frequent shutdowns.

Fault Cause: The cardan shaft’s bearing was worn after 6500 working hours of use, and the lubrication was insufficient, leading to friction and abnormal noise.

Maintenance Solution: Replace the cardan shaft with our ZJ50 W60.5×735 spare part, apply special lubricating grease, and test the power transmission. After replacement, the abnormal noise disappears, the power transmission is stable, and the drilling rig operates normally.

Case 2: SJ600S Piston Pump Leakage

Fault Phenomenon: The SJ600S piston pump had hydraulic oil leakage from the plunger area, resulting in reduced pump pressure (from 70MPa to 55MPa) and decreased fluid transmission efficiency.

Fault Cause: The plunger body assembly’s sealing ring was worn after 4000 working hours of use, leading to oil leakage.

Maintenance Solution: Replace the plunger body assembly with our SJ600S spare part, check and adjust the pump clearance, and test the pump operation. After replacement, there is no oil leakage, the pump pressure is restored to 70MPa, and the pump operates normally.

Case 3: JC70B Drawworks Brake Failure

Fault Phenomenon: The JC70B drawworks’ brake system failed during hoisting operations, the brake could not lock firmly, and the load slipped, posing a safety hazard.

Fault Cause: The PSZ-65A disc brake block was severely worn (wear thickness exceeding 4.5mm), and the friction coefficient decreased, leading to insufficient braking force.

Maintenance Solution: Replace the disc brake block with our PSZ-65A spare part, adjust the brake clearance, and test the braking performance. After replacement, the brake locks firmly, the load does not slip, and the drawworks operates safely.
