What do you need to pay attention to using a radiant tube?
1, where the components can work: A ⊕ air humidity less than 95% no explosive and corrosive gases. B operating voltage should be less than 1.1 times the rated value The shell should be effectively grounded. Insulation resistance ≥1MΩ Dielectric strength: 2KV / 1min.
2, the electric tube should be fixed positioning, radiant tube effective heating zone must be all immersed in liquid or metal solid. Found that the surface of the pipe body when the scale or carbon should be timely clean and then so as not to affect the heat and cut short life.
3, heating fusible metal or solid salt, alkali, asphalt, paraffin, etc. should first reduce the use of voltage until the medium after melting to rise to the rated voltage.
4, heating the air should be evenly arranged in the arrangement so that the components have a good heat dissipation conditions so that the flow of air can be fully heated.
5, heating the salt should be considered when the safety measures to prevent the explosion.
6, the wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, moisture; radiant tube lead wire should be able to withstand the long-term wiring part of the temperature and heating load screw tightening should avoid excessive force.
7, the components should be stored in a dry place. If the insulation resistance is less than 1MΩ for a long period of time, it can be dried in an oven at about 200 ° C or the voltage is energized until the insulation resistance is restored.
8, the electric tube outlet side of the magnesium oxide powder in the use of places to avoid contaminants and water infiltration, radiant tube to prevent the occurrence of leakage accidents
