Flange heating tube manufacturers talk about air heaters

Air heater manufacturers install a primary coil with more turns and a secondary coil with fewer turns on the same core. The voltage ratio of input and output is equal to the ratio of the number of coil turns, and the energy remains unchanged. Therefore, the secondary coil generates a large current under low voltage conditions. For induction heaters, the bearing is a short-circuited single-turn secondary coil, which generates a large amount of heat through a large current under low AC voltage. The heater itself and the yoke are kept at room temperature. Since this heating method can induce current, the bearing will be magnetized.

It is important to ensure the future magnetization of the bearing so that it will not absorb metal magnetic chips during operation. FAG induction heater has an automatic magnetization function. It uses the eddy current generated by the metal in the alternating magnetic field to heat itself, and is usually used for metal heat treatment. The principle is that when thick metal is in the alternating magnetic field, current is generated due to electromagnetic induction. After the thick metal generates current, the current will form a spiral flow path inside the metal, so that the heat generated by the current is absorbed by the metal itself, causing the metal to heat up rapidly.

The high-temperature resistance wire is evenly distributed in the high-temperature resistant stainless steel seamless pipe, and the crystalline magnesium oxide powder with good thermal conductivity and insulation properties is densely filled in the gap. This structure is not only advanced, has high thermal efficiency, but also heats evenly. When the current in the high-temperature resistance wire passes through, the heat generated diffuses to the surface of the metal tube through the crystallized magnesium oxide powder, and then transfers to the heating part or the air to achieve the purpose of heating.

The air electric heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 850℃. In the application range of the heater, the air heater is a widely used heater. We usually call it an air heater. In fact, it can be divided into many types according to the different heating gases. Common ones are nitrogen heaters and hydrogen heaters. These can also be called pipeline gas heaters.

It has been widely used in many scientific research and production laboratories such as aerospace, weapons industry, chemical industry and colleges and universities. It is particularly suitable for automatic temperature control and large flow high temperature joint system and accessory tests. The air electric heater has a wide range of uses: it can heat any gas, and the hot air generated is dry, water-free, non-conductive, non-combustion, non-explosion, non-chemical corrosion, non-pollution, safe and reliable, and the heating space is heated quickly (controllable).
