Safety precautions for the use of single-head heat pipes. Single-head heat pipes are used in plastic packaging, small mold heating, injection molding machine hot nozzle heating, hot press molding machinery, cigarette machinery, semiconductor eutectic welding, die casting input channel heating and runnerless injection, Heating of equipment such as the cooling effect when various gases expand. The following single-hair heat pipe manufacturers will explain to you:
Heater
1. The single-head heat pipe element is allowed to work under the following conditions: The relative humidity of the air is not more than 95%, and there is no explosive and corrosive gas. The working voltage should not be greater than 1.1 times the rated value, and the housing should be effectively grounded. Insulation resistance≥1MΩ Dielectric strength: 2KV/1min.
2. Safety measures should be considered when heating nitrate to prevent explosion accidents.
3. The magnesium oxide powder at the outlet end of the electric heating tube should avoid the infiltration of pollutants and moisture in the place of use to prevent leakage accidents.
4. The components should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, they can be dried in an oven at about 200°C, or the voltage can be reduced and heated until the insulation resistance is restored.
5. The components should be arranged crosswise and evenly when heating the air, so that the components have good heat dissipation conditions, so that the air flowing through can be fully heated.
6. The single-head electric heating tube should be well positioned and fixed, and all the effective heating areas must be immersed in liquid or solid metal, and empty burning is strictly prohibited. When it is found that there is scale or carbon on the surface of the tube, it should be cleaned up and used in time to avoid affecting the heat dissipation of the single-head electric heating tube and shortening its service life.

7. 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, and excessive force should be avoided when tightening the wiring screws.
8. When heating fusible metals or solid nitrates, alkalis, bitumen, paraffin, etc., the operating voltage should be lowered first, and the voltage can be increased to the rated voltage after the medium is melted.
According to the working environment of the single-hair heat pipe, it is generally divided into dry heating and heating liquid. Single-hair heat pipes are widely used, but the safety of use also requires us to always pay attention. The safety precautions for single-hair heat pipes are here.
