Safety measures and heat dissipation conditions of electric heaters

The electric heater should be well positioned and fixed. The effective heating area must completely penetrate into the liquid or metal solid, and empty burning is strictly prohibited. When it is found that there is scale or carbon on the surface of the tube body, it should be cleaned and reused in time, so as not to affect the heat dissipation and shorten the use time.

When the electric heater heats fusible metals or solid nitrates, alkalis, bitumen, paraffin, etc., the operating voltage should be lowered first, and the rated voltage can be raised only after the medium is melted. When heating the air, the elements should be evenly arranged in a cross, so that the elements have good heat dissipation conditions, so that the air flowing through can be fully heated.

Safety measures should be considered when electric heaters heat nitrate 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. When tightening the wiring screws, avoid excessive force.

The elements 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 the insulation resistance can be restored. The magnesium oxide powder at the outlet end of the electric heating tube can avoid the infiltration of pollutants and moisture in the use site, and prevent the occurrence of electric leakage accidents.

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

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 evenly distributed along the central axis of the tube. The gap is filled and compacted with magnesia sand with good insulating and thermal conductivity. Sealed with silicone or ceramic at both ends, this metal armored heating element can heat air, metal molds and various liquids.
