A complete rice processing production line is a complex mechanical system. Various issues can arise during operation, often leaving operators unsure of how to proceed. Familiarizing oneself with potential faults and their causes is essential; this not only facilitates preventive maintenance but also ensures timely resolution when problems occur.
1. Screw Mixer Faults:
① Mixer shaft fails to rotate: Causes include excessive feeding, drive belt slippage, etc. ② No discharge at the outlet: Causes include incorrect motor rotation direction, outlet blockage, broken mixer blades, etc.
2. Electrical Faults:
These generally fall into two categories:
① Individual unit fails to start: Common causes include poor contact or broken wires in the control circuit, burnt-out AC contactor coils, etc.
② Entire system fails to start: Common causes include low voltage, phase loss in the power supply, poor wiring contact, broken control circuit wires, blown fuses, etc.
3. Motor Faults:
The production line comprises over ten motors of various sizes; thus, motor malfunctions cannot be overlooked. Excessive temperature is a primary cause of motor failure. Causes for overheating include lack of bearing lubrication, debris entering the bearings, bearing damage, or motor overload.
4. Airlock (Rotary Valve) Faults:
Poor airtightness can cause product bags to be sucked upward. Common causes include air leaks at connection points and impeller wear. If the impeller is worn, the manufacturer suggests attaching a rubber strip to its outer edge.
Through this explanation provided by the manufacturer of the 200-ton rice processing equipment, we hope you have gained a better understanding of the potential faults and causes associated with these production lines. Personnel who regularly operate this equipment should be thoroughly familiar with this information.
