1. Components are allowed to work under the following conditions: A. The relative humidity of the air is not more than 95%, no explosive and corrosive gases. B. The operating voltage should not be greater than 1.1 times the rated value, and the housing should be effectively grounded. C. Insulation resistance ≥1MΩ Dielectric strength :2KV/1min
2, the electric heating tube should be positioned and fixed, and the effective heating area must be immersed in liquid or metal solid, and air burning is strictly prohibited. When it is found that there is scale or carbon on the surface of the pipe body, it should be cleaned and used again in time to avoid the shadow and heat dissipation and shorten the service life.
3. When heating fusible metal or solid nitrate, alkali, leaching, paraffin, etc., the use voltage should be reduced first, and the rated voltage can be increased after the medium is melted.
4, heating the air elements should be crossed evenly arranged, so that the elements have good heat dissipation conditions, so that the flow of air can be fully heated.
5. Safety measures should be considered when heating nitrate to prevent explosion accidents.
6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media and water; The wiring should be able to withstand the temperature and heating load of the wiring part for a long time, and the fastening of the wiring screws should avoid excessive force.
7, the component should be stored in a dry place, if the insulation resistance is less than 1MΩ for a long time, it can be dried in the oven at about 200 ° C, or reduce the voltage and power heating until the insulation resistance is restored.
8. The magnesium oxide powder at the outlet end of the electric heat pipe should be avoided by pollutants and water infiltration in the use place to prevent the occurrence of leakage accidents. High temperature wire, thermocouple, bimetal thermometer, temperature control instrument.
