The precautions for the use of cast aluminum heaters are as follows:
1. The working voltage must not exceed 10% of the rated value; the relative humidity of the air is not more than 95%, and there is no explosive or corrosive gas.
2. The wiring part is placed outside the heating layer and the insulation layer. The outer casing should be effectively grounded; avoid contact with corrosive, explosive media and moisture; the lead wire should be able to withstand the temperature of the wiring part and the heating load for a long time. Avoid excessive force.
3. The Industrial Electric Cast In Aluminum Heater should be placed in a dry place. If the insulation resistance is less than 1MΩ due to long-term placement, it can be baked in an oven of about 200 degrees Celsius for 5-6 hours to return to normal. Or reduce the voltage and heat it until the insulation resistance is restored.
4. The metal casting heater should be positioned and fixed, and the effective heating zone must be closely attached to the heated body. When it is found that there are dust or contaminants on the surface, it should be cleaned and reused in time to avoid heat dissipation and shorten the service life.
5. The magnesium oxide powder at the outlet end of the Industrial Electric Cast In Aluminum Heater is protected from the infiltration of pollutants and moisture in the place of use to prevent the occurrence of electric leakage accidents.
The metal tubular electric heater element (electric heating tube) is a crystalline magnesium oxide powder in which a heating element is placed in a metal tube and is closely filled with a good heat resistance, thermal conductivity and insulation in a void portion, and is processed by other processes. to make. The utility model has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life. Widely used in a variety of saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, hot stamping and other devices. The electric heating tube is an electrical component that converts electrical energy into heat energy. Because of its low price, convenient use, convenient installation and no pollution, it is widely used in various heating occasions. The electric heating tube is used for the classification of the oven and the heat sink is used for the sauna electric heating tube.
