Function introduction and attention points of fin electric heater
The fin-type electric heater is a metal fin that is wound on the surface of the common element. Compared with the common element, the heat dissipation area is expanded by 2 to 3 times, that is, the surface power load allowed by the fin electric heater is 3 ~ 4 times. Due to the shortened length of the electric heater, its own heat loss is reduced. Under the same power conditions, it has the advantages of fast temperature rise, uniform heat generation, good heat dissipation performance, high thermal efficiency, long service life, small heating device volume, and low cost. . Reasonable design according to user requirements, easy to install. Products are widely used in machinery manufacturing, automotive, textile, food, home appliances and other industries, especially in the air curtain air curtain industry. Commonly used for plastic packaging, small mold heating, analytical instruments, cigarette industry, footwear industry, semiconductor eutectic welding, heating of die casting input channel, and no-injection injection, cooling effect when various gases expand, etc.
Features:
1. Small size and large heating power.
Second, it can heat various media in various occasions, such as explosion-proof occasions.
3. The heating temperature is generally up to 720 ℃.
Fourth, the heating system can be fully automated, including the DCS system to control the electric heating system.
Fifth, long service life, with multiple protection systems, safe and reliable.
Electric heaters are dangerous goods during work. Please keep this in mind. In addition, their maintenance is also very important. Because electric heaters work with electricity, there will be certain potential dangers, so about electric heater circuits The maintenance is very important. Through the above explanation, it is estimated that you already have an in-depth understanding of our product. I hope my explanation can help you.
Precautions for using electric heater:
1. Components are allowed to work under the following conditions:
A. The relative humidity of the air is not more than 95%, without explosive and corrosive gases.
B. The operating voltage should not be greater than 1.1 times the rated value, and the enclosure should be effectively grounded.
C. Insulation resistance ≥1MΩ Dielectric strength: 2KV / 1mi n
2. The electric heater should be positioned and fixed. The effective heating area must be immersed in liquid or metal solid. Empty burning is strictly prohibited. When scale or carbonization is found on the surface of the pipe body, it should be cleaned and reused in time to avoid shadow cooling and shorten the service life.
3. When heating fusible metals or solid nitrates, alkalis, bitumen, paraffin, etc., the operating voltage should be reduced first, and the medium can be raised to the rated voltage after melting.
4. When heating the air, the components should be arranged evenly, so that the components have good heat dissipation conditions, and the flowing air can be fully heated.
5. When heating nitrate, safety measures should be considered to prevent explosion accidents.
6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media and moisture; the lead wire should be able to withstand the temperature and heating load of the wiring part for a long time. Avoid excessive force when tightening the screw.
7. The components should be stored in a dry place. If the insulation resistance is less than 1MΩ due to long-term storage, it can be dried in an oven at about 200 ° C or reduced in voltage and heated until the insulation resistance is restored.
8. The magnesium oxide powder at the outlet end of the electric heater is protected from the penetration of pollutants and moisture in the place of use to prevent the occurrence of electric leakage accidents.
