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

• Pump Heads (SB68J-5.1.0A, SB45ZJC-35.1.0): For high-pressure oilfield pumps, check the sealing surface every 125 working hours to avoid leakage caused by debris accumulation; replace the sealing gasket every 320 working hours, and do not use expired gaskets (expired gaskets will lose elasticity and cause leakage); clean the pump head surface every 175 working hours in corrosive environments.

• Bearings (7314ACM GB/T292-1994, 7314ACM W21157314): Check the bearing temperature every 100 working hours, and stop the machine for inspection if it exceeds 80℃ to avoid bearing damage; add lubricating oil every 140 working hours, and use the specified model of lubricating oil (do not mix different types of lubricating oil); check the speed-diameter product every 500 working hours to ensure it does not exceed API 685-2022 limits (500,000 for oil lubrication); 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.

• Impellers and Transmission Parts: Clean the impeller surface every 85 working hours to remove sand and attachments; check the impeller wear every 480 working hours, and replace it when the wear exceeds 0.2mm; check the V-belt tightness every 75 working hours, and replace it if there is obvious wear or cracks; check the pump pulley and motor pulley every 105 working hours for deformation.

• Fasteners: Check the tightness of bolts, nuts, split pins, rivets and spring washers every 80 working hours, and fasten or replace them in time; for GB/T standard fasteners (Spring washer 18 GB/T93-1987, Split pin 4×30 GB/T91-2000, Rivets 2×6 GB/T827-1986), do not replace them with non-standard products; replace spring washers every 700 working hours to avoid loosening caused by fatigue.

• Motor Accessories: Check Motor W31710014, W31710123, YB2-250M-4 every 110 working hours to ensure stable power output; check the motor wiring every 155 working hours to avoid poor contact; clean the motor surface every 210 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.
