Precautions for Heater
1. The element is allowed to work under the following conditions:
A. Relative humidity of air not greater than 95%, no explosive or corrosive gases. Except for explosion-proof heaters
B. Working voltage should not exceed 1.1 times the rated value, and the shell should be effectively grounded.
C. Insulation resistance ≥1MΩ, dielectric strength: 2KV/1min.
2. The electric heating tube should be properly fixed, and the effective heating area must be completely immersed in liquid or solid metal. Do not burn in air. If scale or carbon deposits are found on the tube surface, clean them promptly to avoid affecting heat dissipation and shortening service life.
3. When heating fusible metals or solid nitrates, alkalis, asphalt, paraffin, etc., first reduce the operating voltage, and only after the medium melts can it be raised to the rated voltage.
4. When heating air, elements should be arranged crosswise and evenly to ensure good heat dissipation and full heating of the passing air.
5. When heating nitrates, safety measures should be considered to prevent explosion accidents.
6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and moisture. The lead wires should be able to withstand the temperature of the wiring part and the heating load for a long time. Avoid excessive force when tightening the wiring screws.
7. Elements should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, dry them in an oven at about 200°C or apply voltage to heat until the insulation resistance is restored.
8. The magnesium oxide powder at the outlet end of the electric heating tube should be protected from pollutants and moisture in the use environment to prevent leakage accidents.
