Currently, many companies electromagnetic heater is chosen tech skills Equipment; Here we give you a description of the electromagnetic heater used in the film blowing machine electromagnetic heater used in the blown film crew, and not only save energy, produce progress? power, temperature control and accurate, and also than the traditional resistance wire heating using long life, fast heating, safe, reliable, maintenance-free characteristics. This article will start with its principles to us, and which detail the strengths are: First, the principle of electromagnetic heater: Electromagnetic heater is a use of the principle of electromagnetic induction to convert electrical energy into heat energy equipment. 380V to 220V may communicate electrically, rectified into direct current, and then filtering the DC, the use of SCR IGBT may then serve as a communication DC, high frequency magnetic force lines occur in the induction coil, the induction coil within the outer conductor of the workpiece occurs vortex relying autogenous heat resistance. Second, the electromagnetic heater working methods: As electric coil heating method is a method to heat conduction through touch spread the barrel, just close to the appearance of the inside of the cylinder barrel on the heat spread ability, such large heat outside portion is lost to the air, there is heat conduction loss, and causes the ambient temperature rises. Other resistance wire heating there is a defect that is a low power density, in some of the higher temperature of the heating needs of the occasion can not be used to it. The electromagnetic heating skills through electromagnetic induction heating of the metal cylinder itself, and can be based on the details must be wrapped in a cylinder of external thermal insulation material thickness, thus greatly reducing heat loss, improve the thermal power, which festival electric effect is very obvious, up to 30% to 80%. Because electromagnetic heating coil itself does not generate heat, and is the choice of insulation materials and high temperature cable production, it is not like there is a resistance wire electric lap of the original state of oxidation at high temperatures shorten the service life of the doubt. Third, electromagnetic heaters strengths: 1, heat, heating speed, so that the cylinder direct heat. 2, energy, money and electromagnetic heater thermal power up to 90%, compared with the resistance wire can save 30% -80%. 3, when no fire safety, electromagnetic heater, fire demand satisfaction, can be used in place of high fire demands. 4, green, green no emissions, waste and noise pollution, clean, green, greatly improved production workshop working environment. 5, the device easy, just connect to the use of electromagnetic heating coil. Use whatever they want. 6, the output power can be flexibly conditioning to get accustomed to the size of occasions with different power requirements. 7, overheating maintenance, to avoid damage to the IGBT module. 8, plus popular gathering, electromagnetic heating coil appearance does not heat. 9, after reaching the set temperature, without conditioning, active output power is reduced to zero, saving energy.
