Daily maintenance guide for veneer dryers
Veneer dryers are heavy-duty, high-intensity equipment, and their stability and life depend on scientific daily maintenance. The following are maintenance recommendations summarized by a professional maintenance team for users to refer to and implement.
1. Daily inspection items
Check whether the hot air furnace or burner is operating normally and whether the temperature sensor is accurate;
Check whether the conveyor chain or drum rotates smoothly and whether there is any abnormal sound;
Clean the dust in the air supply duct and return air system to prevent uneven air volume;
Observe whether the veneer drying conditions at the outlet are consistent, and adjust the speed or temperature in time.
2. Weekly maintenance points
Check whether the wiring connector in the electrical control cabinet is loose;
Lubricate all drum bearings and sprockets to prevent overheating due to dry friction;
Clean the fan impeller to prevent dust accumulation from affecting the air volume output;
Check whether the heating system and pipeline interfaces are leaking or blocked.
3. Monthly maintenance recommendations
Check the working status of the inverter and PLC control system to see if there are any abnormal voltage or current;
Clean the heat exchanger and furnace thoroughly to ensure thermal efficiency;
Check whether the feeding and discharging devices are stuck or have veneer accumulation, and adjust the belt tension or roller level if necessary;
Make a running curve record of the entire equipment to evaluate the energy consumption and output ratio.
4. Equipment overhaul cycle reference
It is recommended to perform a medium overhaul every 4,000 hours of operation or once a year, and conduct a comprehensive inspection and replacement of wearing parts for the fan, motor, chain, roller, heating system, etc. to ensure long-term stable operation of the equipment under high-intensity environment.
