LCD track heater
LCD crawler heater According to foreign ceramic heater samples and related technical data, the factory has developed a variety of advanced new product series that can meet the heat treatment requirements of various workpieces. Widely used in boiler, chemical, shipbuilding, electric power construction, machinery and other departments of alloy steel structure, pipeline and pressure vessel welding pre-weld preheating, post-weld intermediate hydrogen cleaning, annealing heat treatment, with fast heating, high heat utilization, Energy saving Significant labor intensity, safe and reliable, easy to operate, is a new and practical ideal local heat treatment heater in the welding industry.
The LCD type crawler heater works by placing a primary coil with a larger number of turns and a secondary coil with a smaller number of turns on the same core. The ratio of the input to the output voltage is equal to the ratio of the turns of the coil while the energy remains the same. Therefore, the secondary coil generates a large current under low voltage conditions. For an induction heater, the bearing is a short-circuited, single-turn secondary coil that passes a large current at a lower AC voltage, thus generating a large amount of heat. The heater itself and the yoke remain at normal temperature. Since this heating method can induce current, the bearing will be magnetized. It is important to ensure that the bearing is demagnetized in the future so that it does not attract metal chips during operation. The FAG induction heater has an automatic degaussing function.
The LCD type crawler heater uses a metal to generate eddy currents in an alternating magnetic field to generate heat itself, and is generally used for metal heat treatment and the like. The principle is that when a thicker metal is in an alternating magnetic field, current is generated due to electromagnetic induction. When a thicker metal produces an electric current, the current will form a spiral flow path inside the metal, so that the heat generated by the current flow is absorbed by the metal itself, which causes the metal to heat up quickly.
The LCD crawler heater is an energy-saving device for preheating or secondary heating of fuel oil. It is installed in front of the combustion equipment to warm the fuel oil before combustion, so that it is at a high temperature (105 ° C - 150 ° C). Under the circumstance, the viscosity of the fuel oil is reduced, and the effect of sufficient atomization combustion is promoted, thereby finally achieving the purpose of saving energy. It is widely used in the pre-heating or secondary heating of fuel oils such as heavy oil, asphalt and oil.
