Unternehmensnachrichten über What to Do If a floating fish feed making machine Leaks Oil?

The core causes of oil leaks in fish feed production equipment can be categorized into four main types, covering core components and shortcomings in routine maintenance: First, aging or damage to seals, the most common cause. The screw bearings, motor bearings, and hydraulic system joints of the extruder are equipped with seals (such as O-rings and oil seals). Prolonged exposure to high temperatures (120-160℃ around the extrusion chamber) and vibration can cause these seals to age, crack, and deform, leading to lubricant leakage. Second, lubrication system malfunctions, including excessive lubricant (beyond the oil level), oil deterioration (mixed with dust or raw material residue), and oil line blockages, leading to increased internal pressure and oil overflowing from weak seals. Third, loose component connections. The high-frequency vibrations during operation of the small fish feed pellet making machine can cause oil pipe joints, bolts, and oil pan screws to loosen, creating gaps and leading to oil leaks. Fourth, wear and tear on equipment components. Wear on components such as screw bearings and hydraulic pumps increases clearance, preventing the formation of an effective oil film and causing leakage. For example, in a small fish farm, the single-screw extruder's bearing oil seals hadn't been replaced for a long time, causing them to age and crack. This led to lubricating oil leaking from the bearing end, contaminating the raw materials in the feed hopper. Preliminary inspection methods and leak location techniques for automatic fish food making equipment.

The troubleshooting process should follow the principle of "external appearance first, then internal structure; static conditions first, then dynamic conditions" to quickly pinpoint leaks: First, a static inspection: shut down the machine, disconnect the power, and wait for the equipment to cool to room temperature. Clean the surface oil and observe the oil distribution. The area with the most concentrated oil is the suspected leak point. Focus on checking critical components such as the screw bearing end, motor bearing, hydraulic system oil pipe joints, oil pan, and gearbox. Second, a dynamic inspection: start the small fish food making machine and run it without load. Observe if the leak worsens, and determine if it is related to vibration or temperature rise (if the leak worsens under dynamic conditions, it may be due to loose component connections or bearing wear). Third, auxiliary testing: wipe the suspected leak point with a clean cloth and apply soapy water. If bubbles appear, the leak is confirmed. Simultaneously check the lubricating oil level and quality. If the oil level is too high, drain the excess grease; if the oil is black or contains impurities, replace it.

Key points for oil leak troubleshooting for different types of fish pellet making machines. The structural differences between single-screw and twin-screw extruders lead to different troubleshooting focuses: For single-screw floating fish feed machines, the focus is on checking the oil seals at the screw bearing ends and the connection between the motor and the screw. Because single-screw extruders rely on frictional heat generation, the bearing temperature is higher, and the oil seals age faster. For twin-screw pet pellet making machines, in addition to bearings and joints, the gearbox (the core of the twin-screw meshing transmission), and the connections between the steam heating system and the hydraulic system need additional inspection. These areas have more complex structures and sealing points, making them prone to oil leaks due to improper installation or vibration. Meanwhile, dry extruders require a focus on checking the mechanical transmission parts. For wet fish feed pellet processing machines, which are equipped with steam systems, attention must be paid to the corrosive effects of steam on seals; leaks may be accompanied by water vapor seepage. Through targeted troubleshooting, leak location time can be reduced to within 30 minutes, saving time for subsequent repairs.
