Air Space Dryer Heating Element Tubular With Black Surface Treatment
Electric tubular heating element introduction:
1. Overview of electric heating tubes
The electric heating tube is composed of a metal tube, a spiral resistance wire, a crystalline magnesium oxide powder with good thermal conductivity and good insulation, and is suitable for heating air, oil, water, chemical medium, hot pressing mold, melting salt, alkali and low melting point. Alloys, etc. It has the characteristics of high thermal efficiency, long service life, high mechanical strength, convenient installation, safety and reliability.
The structure of the electric heating tube is simplified, and the tubular electric heating element can be processed into a U shape, a wave type, a spiral type, a straight rod type or the like as needed. The cross section of the component can be divided into circular, elliptical, rectangular, triangular and the like. The components are single-ended or double-ended, with 1 to 3 terminal bars at each end.
2. Electric heating element three-phase connection
In a 380 volt three-phase four-wire circuit, the voltage between any two live wires is 380 volts, and any one of the live and neutral wires can form 220 volts. This system can form three kinds of power sources: single-phase 220 volt power supply, single-phase 380 volt power supply, three-phase 380 volt power supply, the first kind of household is more, the third kind of motor is much used in the third factory, the second is used. Less, only AC welding machines often use a single-phase 380 volt power supply.
The working principle of electric heating tube:
The high-temperature resistance wire is uniformly distributed in the high-temperature resistant stainless steel seamless tube, and the crystalline magnesium oxide powder having good thermal conductivity and insulation performance is densely filled in the void portion, and the structure is not only advanced, but also has high thermal efficiency and uniform heat generation, when high temperature resistance When there is a current in the wire, the generated heat is diffused to the surface of the metal tube by the crystalline magnesium oxide powder, and then transferred to the heated member or the air to achieve the purpose of heating.
Electric tubular heating element features:
1. Most of the hot air circulates in the tank, which has high thermal efficiency and saves energy.
2. Using forced ventilation, the box is equipped with an adjustable air distribution plate, and the material is evenly dried. The heat source can be selected from steam, hot water, electricity, and far infrared.
3. The whole machine has low noise and stable operation. Temperature control, easy installation and maintenance.
4, a wide range of applications, can dry a variety of materials, is a general drying equipment.
Scope of application: Hot air circulation oven is suitable for heat curing, drying and dehydration of materials and products in pharmaceutical, chemical, food, agricultural and sideline products, aquatic products, light industry, heavy industry and other industries. Such as raw materials, traditional Chinese medicine, Chinese medicine decoction pieces, extracts, powders, granules, granules, water pills, packaging bottles, pigments, dyes, dehydrated vegetables, dried melons, sausages, plastic resins, electrical appliances, baking varnish and so on.
