Motor failure is the core cause of electrical system shutdowns in small fish feed pellet making machines. The motor powers the extruder; if it experiences overload, short circuit, phase loss, or winding burnout, it will directly lead to equipment shutdown. Overload is a common type of motor failure, often caused by mechanical problems such as raw material blockage or component jamming. When the motor load exceeds its rated value, the internal thermal protection device will automatically trip, cutting off the power supply and preventing motor burnout. Furthermore, loose wiring or poor contact can lead to unstable power supply, abnormal motor operation, and ultimately shutdown. If the motor operates in a high-temperature environment for extended periods without adequate cooling, it may also trigger overheat protection and shut down. For example, in high-temperature summer environments, large extruders operating continuously in large-scale production are highly susceptible to motor overheating and shutdown if the cooling fan fails.
Control system and sensor failures can also cause the Fish Feed Extrusion Process to shut down. The control cabinet of an extruder contains core electrical components such as frequency converters, contactors, and relays. If these components age, are damaged, or have poor contact, it will lead to abnormal control signal transmission, making it impossible to accurately control the screw speed, feed rate, and temperature, ultimately causing equipment shutdown. Temperature and pressure sensors are critical detection components of the extruder. If these sensors malfunction, they will transmit incorrect signals to the control system, such as false alarms of excessively high temperature or abnormal pressure, triggering the equipment's protective shutdown procedure. For example, if a temperature sensor malfunctions and mistakenly determines that the extrusion chamber temperature exceeds the dangerous threshold of 160°C, it will immediately send a shutdown signal, causing the equipment to stop abnormally.
For the shutdown of the floating fish feed extruder machine caused by electrical system failure, the troubleshooting and solutions are as follows: First, check the power supply and motor to see if the power supply is stable and if the wiring is loose. If the motor trips, first check for mechanical overload problems, and then reset and restart after troubleshooting. Regularly check the electrical components in the control cabinet, clean the dust, and check for signs of aging or burning. Replace damaged components promptly. Calibrate temperature, pressure, and other sensors, and perform regular tests to ensure accurate signal transmission. Replace any damaged sensors immediately. Establish a regular maintenance mechanism for the electrical system, conduct a comprehensive inspection of the motor, control cabinet, sensors, and other components monthly, and perform a deep maintenance once a year. Employ professional electrical maintenance personnel to avoid unauthorized disassembly of electrical components and prevent the fault from escalating.
