How Do I Choose A Heater?
May 11, 2018

Heater operating principle is the use of alternating magnetic field, a more turns of the primary coil and a smaller number of turns of the secondary coil mounted on the same core. The input and output voltage ratio is equal to the number of turns of the coil, and the energy remains constant. Thus, the secondary coil has a high current under low voltage conditions. On the induction heater, the bearing is a short-circuit single-turn secondary coil, in the lower communication voltage conditions through the high current, and thus a lot of heat. The heater itself and the yoke are kept at room temperature. Since this heating method can sense the current, so the bearing will be magnetized. It is important to ensure that the future demagnetization of the bearing, so that in the course of operation will not suck metal debris. FAG induction heaters have automatic demagnetization function

Heater is a commonly used electric heating device. It is small, high heating power, the use of a very wide range, we are more and more inseparable from it. Here I come to us specifically for the next heater, so that we can correctly understand and select: According to the different raw materials, nitrogen heater, stainless steel heater and so on.

The nitrogen heater has the leading operation control and safety supervisory equipment, which can accurately supply the process temperature with the hot equipment and adjust the temperature to the control system to complete the automatic conditioning of the heat load. Selection of closed-circuit heating, heat loss is small, energy-saving effect is remarkable, and can be satisfied with a number of different heat equipment. Low cost of running, fast recovery, and stainless steel heater evenly distributed within the high temperature resistance wire, in the internal structure of the filler, filled with crystalline magnesium oxide powder, when the current through the resistance wire, the crystallization of oxidation Magnesium powder drifted out of the heat, when it is in high temperature conditions, arrived at the adhesion of heat will be sent to, and then to the purpose of heating.

In addition, there are casting heaters, braided heaters and so on. The former is added in the copper and aluminum and other heating in the industrial contact is very tight, generally not widely used, here for us with a pass. The latter is the use of multi-stranded resistance of the wire around the combination of fiber and then heat, in the general contact is not large, here is not repeated.

Heater is related to the electrical equipment, if used improperly, it is easy to form bad results, so I listed for us some of the heater application: first used in the habit of the environment, try to prevent high temperature, moist, corrosive surroundings. Second, in the heater power and rated current and voltage, to prevent its overload fire. It is necessary for the electric heater to be immersed in the object to be heated to prevent it from burning. Heating the special material should be stable, it is necessary to fully understand the characteristics of the material. In the heating to prevent the separation of personnel. Some of the wiring of the heater should also be prevented from being exposed to air. The heater should not be used in a dry, non-corrosive environment.
