Features 1. The electric heater consists of a heating core and a jacket tube. The heating core uses a tubular heating element as a heat source. The sheath tube is made of a thin stainless steel. It has a large heat dissipation area, fast heat transfer, and a terminal device section. Divided into ordinary type (using the system of stretching cup-shaped shell) and special type (bolt-type explosion-proof device shell seal), special type with the explosion-proof logo DIICT4. IP65 series of standards.
2. Flange connection with the fuel tank container body, the jacket will isolate the heating core from the heated fluid. When the electric heater is being repaired, it is not necessary to release the oil in the oil tank. Only the heating core needs to be extracted and replaced. The new heating core can be easily maintained.
3. The contact area between the jacket and the hot oil should be taken into consideration in the design, so that the oil will not be partially carbonized due to the high heating temperature, and it is only suitable for the heating of the oil with good heating effect.
Matters needing attention 1, sheathed tubular electric heater components allow to work under the following conditions: A. The relative humidity of air is not more than 95% and there is no explosive and corrosive gas. B. The working voltage shall not be greater than 1.1 times the rated value and the enclosure shall be effectively grounded. C. Insulation resistance ≥ 1MΩ Dielectric strength: 2KV/1min.
2. The sheathed tubular electric heater electric heating pipe should be well positioned and fixed, and the effective heating area must be completely immersed in liquid or metal solid, and no air burning is allowed. When scale or carbon is found on the surface of the pipe, it should be removed and reused in a timely manner so as not to affect the heat dissipation and shorten the service life.
3. When heating fusible metal or solid-state nitrate, alkali, bitumen, paraffin, etc., the voltage should be reduced first. After the medium is melted, it can rise to the rated voltage.
4. When the air is heated, the components should be evenly arranged, so that the components have good heat dissipation conditions, so that the flowing air can be fully heated.
5, when heating nitrate salt should consider safety measures to prevent explosion accidents.
6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive medium and moisture; the lead wire should be able to withstand the temperature and heating load of the wiring part for a long time, and the wiring screw should be avoided when it is fastened.
7. The components should be stored in a dry place. If the insulation resistance is lower than 1MΩ for a long time, it can be dried in an oven at about 200°C, or the voltage can be reduced and the heating can be performed until the insulation resistance is restored.
8. The magnesium oxide powder of the sheathed tubular electric heater at the outlet end of the electric heat pipe avoids the infiltration of pollutants and moisture in the place of use to prevent the leakage accident.
