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 15 years of on-site maintenance experience provide the following practical maintenance suggestions (with operation tips to avoid pitfalls):

• Pump Heads (SB68FJC-6.1.0A, SB68JC-5.1.0): For high-pressure oilfield pumps, check the sealing surface every 115 working hours to avoid leakage caused by debris accumulation; replace the sealing gasket every 300 working hours, and do not use expired gaskets (expired gaskets will lose elasticity and cause leakage); clean the pump head surface every 165 working hours in corrosive environments.

• Pump Couplings (SB68-1.3, SB56JC-29.2): Check the coupling alignment every 80 working hours, and adjust it in time if misalignment exceeds 0.15mm (excessive misalignment will cause vibration and bearing damage); check the coupling wear every 500 working hours, and replace it when the wear exceeds 0.2mm; avoid hitting the coupling during maintenance, as this will damage the internal structure.

• Bearings and Seals: Check the bearing temperature every 90 working hours, and stop the machine for inspection if it exceeds 80℃ to avoid bearing damage; add lubricating oil every 130 working hours, and use the specified model of lubricating oil (do not mix different types of lubricating oil); check the oil level through the oil level mirror every 70 working hours, and add oil in time; replace mechanical seals every 1050 working hours to avoid leakage.

• Fasteners: Check the tightness of bolts, nuts and studs every 70 working hours, and fasten them in time (do not over-tighten, which will damage the thread); for GB/T standard fasteners (such as Nut M16 GB/T41-2000, Stud M16×75 GB/T899-1988), do not replace them with non-standard products; replace spring washers every 650 working hours to avoid loosening caused by fatigue.

• Motor Accessories: Check поворотный знак электродвигателя HTY82.10 every 100 working hours to ensure it displays correctly, avoiding pump damage caused by reverse rotation; check the motor pulley tightness every 95 working hours, and adjust it in time to avoid power loss.

• 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.
