The core process and key points for seal replacement. Replacement must follow the steps of "power off and cooling - disassembly and cleaning - precise replacement - resetting and inspection" to avoid secondary damage: The first step is to power off and cool down, and after stopping the machine, wait for the automatic fish food making Once the core component temperature of the equipment has dropped below 50℃, disconnect the power supply, remove the equipment's protective cover, and clean the area around the leak point of oil and raw material residue to prevent impurities from entering the interior during disassembly. The second step is to disassemble the components, locating the corresponding parts based on the leak point. For example, if the bearing end is leaking oil, disassemble the screw coupling and bearing housing; if the oil pipe joint is leaking oil, disassemble the joint nut; if the gearbox is leaking oil, disassemble the gearbox cover. Mark the components during disassembly to avoid misalignment during reassembly. The third step is to replace the seals. Remove the aged or damaged seals, wipe the sealing groove with anhydrous ethanol to ensure it is free of oil and impurities, apply a layer of suitable lubricating oil (use high-temperature grease for high-temperature conditions) to the new seal, and insert it into the sealing groove in its original direction, ensuring a tight fit without twisting or deformation. The fourth step is reassembly and inspection. Reassemble the components according to the markings, tighten the bolts and joints, add an appropriate amount of lubricating oil, and start the equipment under no-load for 30 minutes. Observe whether there is still oil leakage, and simultaneously check whether the bearing temperature and equipment vibration are normal.
Key principles for selecting seals for small fish food making machines. Improper selection can lead to rapid damage to seals and renewed oil leaks. Three main principles must be followed: First, suit the operating conditions. For high-temperature areas such as the extrusion chamber and bearing ends, use high-temperature resistant oil seals (temperature resistance ≥180℃), preferably made of fluororubber or PTFE to avoid aging of ordinary rubber oil seals at high temperatures. For hydraulic systems and oil pipe joints, use oil-resistant O-rings made of nitrile rubber to match the characteristics of the lubricating oil. Second, accurately match the dimensions. Measure the inner diameter, outer diameter, and depth of the sealing groove, and select seals with a dimensional error ≤±0.1mm. Seals that are too large or too small will lead to seal failure. Third, select high-quality parts. Prioritize original equipment manufacturer (OEM) or well-known brand seals to avoid cheap, inferior products, which have low material purity, poor wear resistance, and a lifespan only one-third that of high-quality products.
Daily maintenance points for seals in small floating fish feed making machines. Proper maintenance can extend the lifespan of seals and reduce the frequency of oil leaks: First, conduct regular inspections, checking all sealing components every 500 hours of operation for signs of aging or leakage, and replacing seals nearing failure promptly. Second, control the quality of lubricating oil, changing it regularly to prevent oil deterioration and corrosion of seals, and strictly adhering to the oil level line to avoid overfilling and increased pressure. Third, optimize the equipment operating environment by reducing equipment vibration (e.g., reinforcing the base and replacing worn bearings) to reduce vibration fatigue of seals. Fourth, avoid rough handling; handle equipment gently during disassembly to avoid scratching the sealing grooves and seals. Through scientific maintenance, the lifespan of seals can be increased by 50%,
significantly reducing the incidence of oil leaks.
