What are the symptoms of a malfunction in a small fish feed maker machine? - Knowledge

content

The main symptoms of motor failure in small fish feed extruder machines are motor overheating (casing temperature exceeding 80°C), overload tripping, and inability to start. The core causes include excessive load, motor phase loss, winding short circuit, and poor heat dissipation. Troubleshooting steps: Fish Feed Extrusion Process. When the motor trips due to overload, first check for mechanical load issues such as material blockage or screw jamming. If present, resolve the fault. If the mechanical load is normal, check for loose motor wiring or phase loss. Use a multimeter to check if the three-phase current is balanced. If the current is balanced, check if the motor cooling fan is working properly and if the heat sink is excessively dusty. Solutions: Resolve mechanical load faults, reduce the feed speed to ensure the load is within the rated range; tighten loose wiring and repair phase loss issues; clean dust from the heat sink and repair or replace the faulty cooling fan; if the motor windings are short-circuited, contact a professional to repair or replace the motor.

For small fish feed pellet making machines, common transmission system failures include belt drives and speed reducers. Belt drive failures manifest as belt slippage, breakage, and abnormal noise. Causes include belt aging and loosening, pulley misalignment, and insufficient belt tension. During troubleshooting, observe the belt's operating condition. Belt slippage will be accompanied by friction noise; a broken belt will cause the equipment to lose power. Check if the pulleys are aligned; misalignment will lead to premature belt wear. Solutions: Replace aging or broken belts with industrial-grade transmission belts compatible with the equipment; adjust the pulley positions to ensure alignment, with an error not exceeding 0.5mm; adjust the belt tension to ensure proper tightness (the belt should sink 1-2cm when pressed).

For floating fish feed pellet making machines, speed reducer failures manifest as abnormal noise, oil leaks, and unstable output speed. Causes include insufficient lubricating oil, gear wear, and damaged seals. During troubleshooting, check the speed reducer's lubricating oil level; insufficient lubricating oil will increase gear friction and generate noise. Observe for oil leaks and determine if the seals are damaged. Check if the output speed is stable; large fluctuations indicate gear wear. Solutions: Replenish or replace the gearbox's dedicated lubricating oil. Change the lubricating oil in a small extruder gearbox every 500 hours of operation. Replace damaged seals and worn gears. Regularly clean and maintain the gearbox to prevent dust from entering. When troubleshooting motor and transmission system faults, always disconnect the power before proceeding to avoid electric shock or mechanical injury.
