I. Overview of Industrial Electric Hot Runner Coil Heater
Industrial Electric Hot Runner Coil Heater is no stranger to experts, what is the Industrial Electric Hot Runner Coil Heater? Let's talk briefly. The Hot Runner Coil Micro Tubular Heater uses the metal to generate eddy current in the alternating magnetic field to heat itself, and is usually used for metal heat treatment. It is a heating element that is often seen. The hot runner heating coil is a heating component, such as a hot nozzle, a main nozzle, and a heater. There is also a heating wire, which is installed inside the diverter plate. It is similar to the heat, and of course the safety is much higher and the power is much larger.
Second, the working principle of Hot Runner Coil Micro Tubular Heater
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 device is an energy-saving device for preheating or secondary heating of fuel oil and a plastic melting channel for constant temperature heating, which is installed before the combustion device to achieve heating of the fuel oil z before combustion, so that it is at a high temperature (105) At °C-150 °C), the viscosity of the fuel oil is reduced, and the effect of sufficient atomization combustion is promoted, thereby finally achieving the purpose of energy conservation. It is widely used in the pre-heating or secondary heating of heavy oil, asphalt, oil and other fuel oils and rubber and plastics manufacturing.
Also known as the heating element, the heating tube, the scientific name of the tubular electric heater element, is a coiled heating wire (resistance wire) placed in the metal tube, and is filled with good heat resistance and thermal conductivity around the gap portion. And insulating insulating powder (MgO), the ends of the heating wire are connected with a lead rod or a lead wire. The utility model has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life.
The electric heating element is an electrical component that converts electrical energy into heat energy. Because of its low price, convenient use, convenient installation and no pollution, it is widely used in various saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, and air. Heating furnace, drying furnace, drying oven, hot stamping and other devices. The types of electric heating pipes are quite numerous. Common ones are: single-head electric heating pipes, explosion-proof electric heating pipes, and heterogeneous electric heating pipes. The electric heating pipe is a device used for heating in the industry, and the electric heating pipe has the characteristics of simple operation and convenient use, and is an industrially unaccessible device.
