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 and bearing life calculation principles):

• Core Working Components: Check SB68FJ0003 Impeller-FJ every 75 working hours for wear and clogging; replace if wear exceeds 0.15mm or blockage occurs. Clean the impeller regularly to remove slurry deposits—blockages can increase pump load and shorten impeller service life by 3,800 hours. Avoid hitting the impeller with heavy tools, as this can cause cracks and damage.

• Sealing & Transmission Parts: Inspect SB68FJ0044 Mechanical seal assembly and SB68FJ0023 Oil seal every 65 working hours for wear and leakage; replace if cracks or hardening are found. For SB68FJ0015 Bearing 7314ACM and SB68FJ0024 Bearing 6314E, check temperature and noise every 70 working hours; add lithium-based lubricating grease every 90 working hours, and replace if temperature exceeds 85℃. Remember that bearing life is affected by load and speed—avoid overloading to extend L₁₀ life.

• Structural & Auxiliary Components: Check SB68FJ0002 pump casing every 80 working hours for cracks and wear; clean the pump body regularly to prevent slurry corrosion. Check SB68FJ0029 Oil level mirror M20×1.5 every 50 working hours to ensure normal oil level—insufficient lubrication will shorten bearing life by 4,200 hours. Check SB68FJ0020 Oil cup M10×1 regularly to ensure smooth lubricant supply.

• Fasteners: Check all fasteners (including SB68FJ0004 Cap nut M30×2, SB68FJ0012 Bolt M12×35) every 85 working hours for tightness and wear; replace if thread damage occurs. Always use matching washers and spring pads—non-standard washers reduce fastening force and cause component loosening, which can lead to pump vibration and damage. Follow GB/T5782-2000 standard for fastener installation torque.

• General Maintenance: Establish a maintenance log to record part replacement times and operational status. Follow API 682 (4th edition), ISO 281, and relevant national standards 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; avoid placing heavy objects on seals and impellers to prevent deformation.
