Key points for fault diagnosis
Troubleshooting Point 1: Sharp Operating Noise, Sudden Increase in Energy Consumption, and Severe Part Wear
Under normal circumstances, the operating noise of a dog food pellet maker machine should be below 75 decibels, and energy consumption should be stable (the energy consumption ratio is fixed when linked with the extruder). If sharp abnormal noises or friction sounds occur during operation, and energy consumption increases by more than 15% compared to normal, it can be determined that there is a wear fault in the internal parts of the pellet maker. This type of fault is often caused by wear of gears in the pellet maker's gearbox, bearing jamming, or wear of the pressure rollers or die head. For example, after gear wear, abnormal meshing noises will occur during operation, and energy consumption will increase. Bearing jamming will lead to increased operating resistance, a sudden increase in energy consumption, and is accompanied by severe vibration. In this case, the machine should be stopped immediately for inspection to prevent further wear of parts. At the same time, confirm that there are no abnormalities in the linkage of the dog food extruder machine, ruling out the extruder as the cause of the increased energy consumption.
Troubleshooting Point 2: Abnormally High Machine Temperature, Heat Dissipation System Failure
When the dog food pellet mill is running, the machine body temperature should be controlled between 40-50℃. When linked with the extruder, the temperature should not exceed 60℃. If the machine body temperature rises abnormally (above 70℃), and the outer casing feels noticeably hot to the touch, it indicates a failure in the pellet mill's heat dissipation system or excessive friction of internal components. This type of failure mainly falls into two categories: first, blockage of the cooling fan or cooling pipes, leading to poor heat dissipation and increased machine body temperature; second, severe wear of the pressure rollers and die head, increasing friction and generating a large amount of heat, which the heat dissipation system cannot dissipate in time. If the temperature continues to rise, it will cause the pellet mill motor to overheat and shut down for protection. It will also affect the linked operation of the extruder, causing fluctuations in the dog food processing machine's parameters. The heat dissipation system and component wear must be checked promptly.
Troubleshooting Point 3: Abnormal Start-up/Stop Operations or Jamming, Indicating Control System or Mechanical Faults
Under normal circumstances, the dog food pellet making machine starts and stops smoothly. When linked with the extruder, the start and stop are synchronized without jamming. If starting difficulties occur, the machine cannot be restarted after stopping, or jamming or shutdown protection occurs during operation, it can be determined that the pellet mill has a control system or mechanical fault. Control system faults mainly manifest as a malfunctioning control panel, ineffective parameter adjustments, and inability to achieve linked start-up and stop with the extruder. Mechanical faults mainly manifest as jamming of the feeding mechanism, stuck pressure rollers, and clogged die head, causing the pellet mill to malfunction. During troubleshooting, first check the control system (power supply, wiring, control panel), then check the mechanical components. At the same time, confirm that the extruder's linkage signal is normal, eliminate interference in the dog food pellet extruder machine linkage, and quickly locate the faulty part of the pellet mill.
