Maintenance and Maintenance Suggestions

To extend the service life of pump spare parts and ensure the stable operation of pumps—especially SB series pumps and their supporting systems—our professional engineers with more than 18 years of on-site maintenance experience provide the following practical maintenance suggestions (with operation tips to avoid pitfalls):

• Bearings (7314ACM W21157314, 7211B W21157211): Check the bearing temperature every 105 working hours, and stop the machine for inspection if it exceeds 80℃ to avoid bearing damage; add lubricating oil every 145 working hours, and use the specified model of lubricating oil (do not mix different types of lubricating oil); check the bearing load capacity every 500 working hours to ensure it does not exceed the rated dynamic load (156kN for 7314ACM); check the bearing clearance every 500 working hours, and replace the bearing if the clearance exceeds 0.13mm; avoid hitting the bearing during installation, as this will damage the internal structure and reduce its service life.

• Pump Pulleys and Couplings (X11182011, SB34-35.3): Check the pulley surface every 85 working hours to remove dust and attachments; check the pulley wear every 480 working hours, and replace it when the wear exceeds 0.2mm; check the coupling tightness every 75 working hours, and fasten or replace it in time if there is looseness; avoid over-tightening the coupling, as this will cause shaft deformation.

• Impellers and Pump Heads: Clean the impeller surface every 90 working hours to remove sand and attachments; check the impeller wear every 480 working hours, and replace it when the wear exceeds 0.2mm; for pump heads, check the sealing surface every 130 working hours to avoid leakage caused by debris accumulation; replace the sealing gasket every 330 working hours, and do not use expired gaskets.

• Fasteners: Check the tightness of bolts, nuts, cotter pins and spring washers every 85 working hours, and fasten or replace them in time; for GB/T standard fasteners (Nut M18 GB/T41-2000, Cotter pin 4×30 W07075433), do not replace them with non-standard products; replace spring washers every 720 working hours to avoid loosening caused by fatigue.

• Motor Accessories: Check Motor W31710114, W31710116, YB2-225M-4, YB2-250M-4 every 115 working hours to ensure stable power output; check the motor wiring every 160 working hours to avoid poor contact; clean the motor surface every 215 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, and can effectively reduce the frequency of equipment failure.
