Maintenance and Care Suggestions

To extend the service life of spare parts and ensure the stable operation of SB6×8FJ centrifugal sand pumps, our engineers with 28+ years of on-site oilfield maintenance experience provide practical tips (with avoidable pitfalls, based on real maintenance experience):

• Core Components: Check SB68FJ0001S Pump head-FJ every 80 working hours for wear and leakage; replace if wear exceeds 0.15mm or leakage occurs. Clean the pump head regularly to remove slurry deposits—blockages can increase pump load and shorten service life by 3,300 hours. Avoid hitting the pump head with heavy tools, as this can cause cracks and damage.

• Motor & Transmission Parts: Inspect SB68FJ0007S Motor every 70 working hours for temperature, noise, and power output; replace if temperature exceeds 85℃ or power drops by more than 5kW. Check SB68FJ0005S Key C18×105 and SB68FJ0015S Coupling pin sleeve every 90 working hours for wear and deformation; add lubricating grease every 100 working hours to ensure smooth power transmission. Avoid over-tightening the coupling, as this can cause key damage.

• Seals & Rubber Pads: Check SB68FJ0020S and SB68FJ0021S rubber pads every 60 working hours for aging and damage; replace if cracks or hardening are found. Clean the rubber pad contact surface before installation—slurry or debris on the surface can cause leakage. Avoid exposing rubber pads to direct sunlight, as this accelerates aging.

• Fasteners: Check SB68FJ0009S Bolt, SB68FJ0010S Nut M20, and SB68FJ0013S Bolt M10×10 every 85 working hours for tightness and wear; replace if thread damage occurs. Always use matching spring pads and flat pads—non-standard washers reduce fastening force and cause component loosening, which can lead to pump vibration and damage.

• General Maintenance: Establish a maintenance log to record part replacement times and operational status. Follow API 682 (4th edition) and relevant national standards (GB/T5782-2000, GB/T93-1987) for regular equipment inspection, and use only matching SB68FJ series spare parts to avoid system damage caused by mismatched components. Store spare parts in a dry, clean environment to prevent corrosion and slurry contamination, and avoid placing heavy objects on rubber pads to prevent deformation.
