Safety measures and heat dissipation conditions of electric heaters

The electric heater should be well positioned and fixed, and the effective heating area must all penetrate into the liquid or metal solid, and it is strictly forbidden to burn it. When it is found that there is scale or carbon on the surface of the pipe body, it should be cleaned up in time before use, so as not to affect the heat dissipation and shorten the use time.

When heating fusible metals or solid nitrates, alkalis, bitumen, paraffin, etc. with electric heaters, the operating voltage should be lowered first, and the voltage can be raised to the rated voltage after the medium is melted. When heating the air, the components should be arranged crosswise and evenly, so that the components have good heat dissipation conditions, so that the air flowing through can be fully heated.

Safety measures should be considered when heating nitrate with electric heaters to prevent explosion accidents. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and moisture. The lead wire should be able to withstand the temperature and heating load of the wiring part for a long time, and excessive force should be avoided when tightening the wiring screws.

The components of the electric heater should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be dried in an oven at about 200°C, or the voltage can be reduced and heated until the insulation resistance is restored. The magnesium oxide powder at the outlet end of the electric heating tube prevents the infiltration of pollutants and moisture in the place of use to prevent leakage accidents.

The main products of electric heating appliances are: electric boilers, high-density single-ended heating tubes, electric heating tubes for boilers, electric heating tubes for ovens, finned electric heating tubes, automobile electric heating appliances, electric heating tubes, electric heating appliances, explosion-proof electric heating appliances, synthetic electric heating appliances , Storage tank electric heating appliances, high temperature ceramic electric heating appliances, molecular sieve electric heating appliances, circulating electric heating appliances, Huff type electric heating appliances, crawler electric heating appliances, hot water electric heating appliances, fluid circulating electric heating appliances.

The electric heating appliance (electric heating tube) is a metal tube as the shell, and the spiral electric heating alloy wire (nickel-chromium, iron-chromium alloy) is uniformly distributed along the central axis of the tube. The gap is filled and compacted with magnesia sand with good insulation and thermal conductivity. The nozzle Both ends are sealed with silica gel or ceramics. This metal-clad electric heating element can heat air, metal molds and various liquids.
