Electric heating tubes are used more and more widely in today's industrial heating equipment. From time to time, new people join this field. For unfamiliar industries, you need to learn more about this industry in order to adapt to this field more quickly.
The electric heating tube is composed of metal tube, spiral resistance wire and crystalline magnesium oxide powder with good thermal conductivity and good insulation. It is suitable for heating air, oil, water, chemical media, hot pressing mold, melting salt, alkali and low melting point. Alloy etc. It has the characteristics of high thermal efficiency, long service life, high mechanical strength, convenient installation, safety and reliability.
The electric heating tube can be processed into U-shaped, wave-shaped, spiral-shaped, straight-rod-shaped and other shapes as required. The cross-section of the component can be divided into circular, elliptical, rectangular, triangular and other categories.
Components are divided into single-ended or double-ended wiring, each end has 1 to 3 wiring rods.
Electric heating tube three-phase connection: In a 380 volt three-phase four-wire circuit, the voltage between any two live wires is 380 volts, and any live wire and neutral wire can form 220 volts. This system can form three power sources: single-phase 220 volt power supply, single-phase 380 volt power supply, and three-phase 380 volt power supply. The first type is more for household use, the third type is more used in factories, and the second type is used. Few, only AC welding machine often uses single-phase 380 volt power supply.
Electric heating tube types: mica electric heating coil series, copper-clad heater series, spring heating coil series, flange heating tube series, temperature control heater series, tubular heater series, corrosion-resistant heating series, ceramic heater series.
The purpose of electric heating tube: used for heating oil in open or closed oil tank or heating flowing or circulating oil.
