Five essential common sense for pipe heater maintenance

Duct heaters are commonly used in industries such as automotive, textiles, papermaking, manufacturing, and chemicals, achieving ultra-fast drying. Duct heaters offer excellent radiation effects, distinct nodes, and ease of use and maintenance. They are particularly suitable for large drying rooms, ovens, and water drying tunnels used in leather machinery.

So, what happens if duct heaters are not maintained in the manufacturing industry? Failure to maintain them can lead to problems such as water pump startup difficulties, machine switches malfunctioning or damage, and prolonged use leading to carbon brush wear and a lack of bearing grease. To help you better maintain duct heaters, here are some tips for duct heater maintenance.

Daily Maintenance of Duct Heaters:

1. The heater water pump should be inspected regularly based on user usage. If leaks are detected in the water seal or the pump has difficulty starting, repair it immediately.

2. The automatic control box, oil filter, electromagnetic rice cooker, and other electrical components on the heater main unit should be maintained according to general low-voltage electrical maintenance procedures. All performance parameters of the automatic control box are carefully adjusted by the manufacturer before shipment. Users are strictly prohibited from making any modifications.

3. Ensure that the heater control unit is in good condition and inspect it regularly. If any microswitch is malfunctioning or damaged, replace it promptly.

4. The main motor used in most heaters requires no maintenance under normal circumstances. If it malfunctions due to extended use or other reasons, it should be inspected and the carbon brushes checked for wear and bearing lubrication. If necessary, add grease or replace the carbon brushes.

5. During warm weather, when the heater is not in use, periodically restart it 4-5 times for approximately 5 minutes each time to ensure normal operation upon next use.
