Tunnel hot air circulation oven is a drying equipment that utilizes hot air circulation technology. It uniformly transports hot air into the oven through a hot air circulation system to dry materials. The working principle of this oven is to use the convection and radiation of hot air to raise the temperature of the material surface, evaporate moisture, and achieve the purpose of drying. Below, the editor will briefly introduce the maintenance of the tunnel hot air circulation oven:
Regular cleaning: including internal and external cleaning. Internal cleaning requires regular cleaning of material debris, oil stains, and dust inside the tunnel to maintain the cleanliness and hygiene of the oven environment; External cleaning requires removing dust and stains from the outside of the device to maintain a clean appearance.
Check the fan: Regularly check the operating status of the fan to ensure it runs smoothly without any abnormal noise or vibration. Clean the dust and debris on the fan blades, check the lubrication of the fan bearings, and add oil or replace them if necessary.
Power outage handling: When the oven is not in use for a long time, the power should be cut off to save energy and reduce equipment loss. Before carrying out maintenance or cleaning work, the power must be cut off and a warning sign must be hung to prevent accidental electric shock.
Safe use: Ensure that all operators have received professional training and are familiar with the operating procedures and safety precautions of the equipment. Operators should wear necessary personal protective equipment when performing maintenance and cleaning work.
Check the air outlet: Regularly clean the air inlet and outlet to prevent blockages from affecting the circulation efficiency of hot air. Use a soft bristled brush or compressed air to clean the dust and impurities inside the air outlet, ensuring even distribution of air volume.
Calibrate temperature control: Use a standard thermometer to calibrate the temperature inside the oven, ensuring the accuracy and reliability of the temperature control system. Adjust the parameters of the temperature controller based on the calibration results to accurately control the temperature inside the oven within the set range.
Electrical component inspection: Regularly check the connections of electrical components (such as heating tubes, temperature sensors, relays, etc.) for firmness, aging, or damage. Ensure that the grounding system of the equipment is in good condition to prevent electrical faults from causing safety accidents.
Reasonable placement: The oven should be placed in a well ventilated, dry and clean environment, avoiding direct sunlight and rain. Ensure there is sufficient space around the oven for maintenance and cleaning work.
