Common maintenance issues with the electrical system of a fish feed pellet making machine can be categorized into three types. First, motor failure, manifesting as overheating, abnormal noise, or inability to start. This is often caused by overload (excessive feeding speed), poor heat dissipation (fan blockage, high ambient temperature), or insufficient lubrication and wear of bearings. Some older motors may also experience leakage due to aging windings, posing a safety hazard. Second, control cabinet and wiring failures. The dusty and humid environment of feed production can easily lead to corrosion and damage to the insulation layer of wiring, causing short circuits, or oxidation of contactor and relay contacts, resulting in poor contact, manifesting as abnormal equipment start-up and shutdown, and parameter fluctuations. Third, sensor and control system failures. A malfunctioning temperature sensor can lead to uncontrolled extrusion temperature, and a faulty level sensor can cause uneven feeding. These problems directly affect feed quality.

Troubleshooting should follow the principle of "power off first, then troubleshoot; simple problems first, then complex ones." When the motor of a fish food making machine overheats, first check if the feed rate is overloaded. If normal, clean the dust from the cooling fan, check the bearing lubrication, and add lithium-based grease if insufficient. Replace severely worn bearings. If the motor fails to start, use a multimeter to check the power line voltage and winding continuity. After ruling out circuit faults, determine if the motor is burnt out. For control cabinet malfunctions, regularly open and clean the dust, wipe the oxide layer on the contacts with alcohol, check the wiring connections for tightness, and replace any damaged insulation. For sensor malfunctions, calibrate with standard instruments. If the temperature sensor error exceeds ±3℃, replace it to ensure accurate data.

The core of preventing electrical system problems is routine maintenance. Check the motor temperature and wiring appearance before starting the machine daily. Clean the control cabinet and motor dust weekly. Check the insulation performance of the wiring and sensor accuracy monthly. Conduct a comprehensive overhaul of contactors and relays quarterly. Simultaneously, optimize the production environment by installing dustproof and moisture-proof devices around electrical equipment to prevent direct corrosion from dust and moisture, reducing the failure rate at its source.
