Engineer On-Site Maintenance & Avoidance Tips

Combined with 20+ years of oilfield on-site maintenance experience, senior drilling equipment engineers put forward practical maintenance suggestions and key avoidance reminders to maximize the service life of parts and avoid unnecessary faults:

1. Regular inspection cycle: Conduct full inspection of sealing parts, fasteners, and bearing components every 750 hours of continuous equipment operation; check for wear, aging, and looseness, and replace damaged parts in time.

2. Installation specifications: Keep the installation surface clean and free of mud and debris; apply special anti-loosening agent to fasteners during installation, and tighten according to the rated torque to avoid over-tightening causing part fracture.

3. Sealing part maintenance: Do not use sharp tools to scratch the sealing surface during installation; rubber sealing parts should be stored in a cool and dry environment, away from direct sunlight to prevent premature aging.

4. Model matching: Strictly select parts according to equipment model and original part number; do not mix different specifications of O-rings, bearings, and fasteners to avoid performance mismatch and equipment damage.

5. Load control: Do not overload the equipment for a long time, so as not to exceed the bearing limit of spare parts and cause premature wear and tear; replace vulnerable parts in advance before the equipment undergoes heavy-load continuous operation.
