Precautions For The Use Of Hot Runner Heating Coils
The hot runner heater is a new type of equipment specially developed for heating gas fluids. Do you know any precautions during use?
Precautions for the use of hot runner heating coils:
1. The working voltage must not exceed 10% of the rated value; the relative humidity of the air is not more than 95%, non-sexual and corrosive gas.
2. The wiring part is placed outside the heating layer and insulation layer, and the shell should be grounded; avoid contact with corrosive, sexual 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 the wiring screws should be avoided when tightening Excessive force.
3. The hot runner heating ring should be placed in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be baked in an oven at about 200 degrees Celsius for 5-6 hours to return to normal. Or reduce the voltage and heat until the insulation resistance is restored.
4. The hot runner heating ring should be well positioned and fixed, and the heating area must be closely attached to the heated body, and empty burning is strictly prohibited. When dust or contaminants are found on the surface, they should be removed and reused in time, so as not to affect heat dissipation and shorten the service life.
5. 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. Even if the internal heating material of the hot runner heating coil is damaged, the external ceramic components can still be reused.
