Maintenance and Maintenance Suggestions

To extend the service life of pump spare parts and ensure the stable operation of pumps—especially SB series pumps in oilfield solid control systems—our professional engineers with more than 20 years of on-site maintenance experience provide the following practical maintenance suggestions (with operation tips to avoid pitfalls):

• Pump Heads (SB68FJ-5.1.0, SB56J-29.1.0): For pumps in solid control systems, check the sealing surface every 125 working hours to avoid leakage caused by debris accumulation in fluid processing; replace the sealing gasket every 330 working hours, and do not use expired gaskets (expired gaskets will lose elasticity and cause leakage); clean the pump head surface every 180 working hours in corrosive environments.

• Bearings and Seals (7210ACM W21157210, Oil seal 65×90×12 GB/T9877.1-1988): Check the bearing temperature every 110 working hours, and stop the machine for inspection if it exceeds 80℃ to avoid bearing damage; add lubricating oil every 150 working hours, and use the specified model of lubricating oil (do not mix different types of lubricating oil); check the oil seal wear every 135 working hours, and replace it when the wear exceeds 0.1mm; avoid hitting the bearing during installation, as this will damage the internal structure.

• Impellers and Couplings: Clean the impeller surface every 95 working hours to remove sand and attachments in solid control systems; check the impeller wear every 490 working hours, and replace it when the wear exceeds 0.2mm; check the coupling tightness every 80 working hours, and fasten or replace it in time if there is looseness; avoid over-tightening the coupling, as this will cause shaft deformation.

• Fasteners: Check the tightness of bolts, nuts, keys and split pins every 90 working hours, and fasten or replace them in time; for GB/T standard fasteners (Round nut M68×2-LH GB/T812-1988, Key B18×100 GB/T1096-2003, Split pin 4×30 GB/T91-2000), do not replace them with non-standard products; replace spring washers every 750 working hours to avoid loosening caused by fatigue.

• Motor Accessories: Check Motor W31710113, W31710116 every 120 working hours to ensure stable power output (45kW); check the motor wiring every 165 working hours to avoid poor contact; clean the motor surface every 225 working hours to ensure heat dissipation.

• Establish a complete pump maintenance file, record the replacement time and operation status of each spare part, which is convenient for subsequent maintenance and spare part replacement in solid control systems, and can effectively reduce the frequency of equipment failure.
