The Principle Of The Heater
May 17, 2018

Electromagnetic heaters are a device that uses electromagnetic induction to convert electrical energy into heat. Electromagnetic manipulator will 220V / 380V, 50 / 60Hz communication rectifier circuit rectifier into a direct current, and then through the control circuit will be converted into DC frequency of 20-40KHz high frequency high voltage, high-speed high-frequency high-voltage current flow The magnetic field of the alternating magnetic field lines through the magnetic metal (iron, cobalt, nickel) data in the metal body will occur numerous small eddy current, so that the metal data itself high-speed fever, and then reach The intention of heating metal material.

Electromagnetic heater operating principle is: the 220V or 380V communication power, converted to DC after conversion, and then the DC filter, the use of IGBT or silicon can then become a communication, in the induction coil within the high frequency magnetic field lines, is the induction The inner conductor of the coil has an eddy current dependent self-generated internal resistance. Electric heating method is through the touch conduction method to the heat transfer to the barrel, as long as the inside of the barrel in front of the heat to pass to the barrel, so that most of the heat outside the loss to the air, there is a heat conduction loss , And cause the ambient temperature to rise. Another resistance wire heating there is a drawback that the power density is low, in some high temperature requirements of the heating can not get used to the occasion. Electromagnetic heating technology is the principle of electromagnetic induction to make the metal barrel itself fever, and according to the specific circumstances in the barrel outside the package must be wrapped in a certain thickness of thermal insulation information, thus greatly reducing the heat loss, improve the thermal efficiency, thus saving electricity The role is very obvious, up to 30% to 75%. As the electromagnetic heating ring itself does not heat, and is the choice of insulation materials and high temperature cable production, so there is no like the original electric coil resistance wire in the high temperature oxidation and shorten the life of the doubt, with long service life, heating rate , No need to repair and other advantages, reducing the repair time, reduce the cost. Has been widely used in the plastic products company, greatly reducing the company's production costs.

Water pipe heater selection of stainless steel cylinder, small size, small footprint, mobile convenience, with strong corrosion resistance, stainless steel liner and stainless steel shell between the choice of thickening insulation layer, the lowest degree of loss of temperature, to maintain Temperature, saving energy. High-quality heating elements (stainless steel heating pipe) of the main components of the selection of imported materials, the processing process also uses a leading production equipment and technology, with the same voltage, the highest performance. Its insulation, pressure resistance, moisture resistance are higher than the national standard, the use of safe and reliable. Water flow planning is reasonable, uniform heating, no high, low temperature dead, high thermal efficiency. Pipeline heater installed in the domestic well-known brands of thermostat, the user can set the temperature freely. All equipment overheating maintenance, used to control the temperature and water over-temperature maintenance, to prevent heating. Components and systems damage.

Water pipe heater heating element selection 1Cr18Ni9Ti stainless steel seamless tube for the maintenance of casing, 0Cr27Al7MO2 high temperature resistance alloy wire, crystalline magnesia powder, by tightening technology, so that the use of electric heating components to ensure that life. Control some use of high-precision digital temperature controller, solid state relay, etc. constitute adjustable temperature, temperature system to ensure the normal operation of the electric heater. High-quality heating element (stainless steel heating pipe) of the main components selected imports Information, processing process also uses a leading production equipment and technology, with the same voltage, the highest performance. Its insulation, pressure resistance, moisture resistance are higher than the national standard, the use of safe and reliable, reasonable water flow planning, heating evenly, no high, low temperature dead, high thermal efficiency, water pipe heater installed a well-known brands of temperature controller , The user can set the temperature freely. All equipment overheating maintenance, used to control the temperature and water over-temperature maintenance, to prevent damage to the heating components and systems.
