Tubular electric heaters are composed of metal tubes, spiral resistance wires, and electrical-grade magnesium oxide powder with good thermal conductivity and insulation, as well as terminals. They are widely used for heating liquids, air, etc. The tubular heater components should be stored in a dry place. If the insulation resistance drops below 1 megohm due to long-term storage, it can be restored by drying in an oven at about 200°C for several hours.
Tubular electric heaters have seen rapid development in both household and industrial applications, with various types of electric heating appliances emerging and becoming widely used, especially in households. The invention of nickel-chromium alloys laid the foundation for the development of the electric heating appliance industry.
Daily maintenance of tubular electric heaters:
1. Ensure the oil tank, oil pipes, and oil filter solenoid valve are clean to prevent dirt from blocking the oil circuit.
2. Ensure the thermal control components are in good condition. Regularly inspect them. If the micro switch is found to be malfunctioning or damaged, replace it promptly.
3. Use antifreeze suitable for the ambient temperature as the circulating heating medium in the heater circulation system.
4. After the heater has been running for a period, unscrew the glow plug to clean carbon deposits. If the glow plug wire is burned out, remove and replace it with a new one.
5. If excessive carbon deposits reduce thermal efficiency, clean the heat sink fins inside the water jacket and the carbon deposits in the combustion chamber.
6. If the heater's air intake pipe, exhaust pipe, and oil drip pipe are blocked by mud, clean and unblock them promptly. Keep the heater compartment clean and avoid placing flammable items nearby.
7. During warm seasons when the heater is not in use, start it 4–5 times regularly, each time running for about 5 minutes, to ensure normal operation when used next time.
8. Regularly inspect the heater water pump based on usage. If the water seal component leaks or the pump has difficulty starting or running, repair it promptly.
9. The automatic control box, fuel filter solenoid valve, and other electrical components on the heater main unit should be maintained according to general low-voltage electrical appliance maintenance methods. All performance parameters of the automatic control box have been carefully debugged by the manufacturer before shipment; users should not alter them arbitrarily.
10. The main motor used in the heater typically does not require maintenance for 5000 hours under normal conditions. If it malfunctions due to prolonged use or other reasons, inspect it, check carbon brush wear or bearing lubrication, and add grease or replace carbon brushes if necessary.
