Precautions for the use of cast aluminum heaters
The cast aluminum heating plate is a tubular electric heating element as the heating element, the element is bent into a mold, and the aluminum is cast into a variety of products. There are heating rings, air-cooled heating rings (with air grooves inside and outside, and water-cooled heating rings (with water pipes). Flat panels, right-angle panels, etc. What are the problems that need to be used when using it?
1. The working voltage must not exceed 10% of the rated value; the relative humidity of the air is not more than 95%, and there is no explosive and corrosive gas.
2. The wiring part is placed outside the heating layer and insulation layer, and the shell should be effectively grounded: 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 the wiring screws should be avoided when tightening Excessive force.
3. It should be placed in a dry place. If the insulation resistance is lower than 1MQ 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 turn on heating until the insulation resistance is restored.
4. Positioning and fixing should be done, the effective heating area must be closely attached to the heated body, and empty burning is strictly prohibited. When dust or pollutants are found on the watch, it should be cleaned up in time to avoid heat dissipation and shorten the service life.
5. The magnesium oxide powder at the outlet end of it should avoid the infiltration of pollutants and moisture in the place of use. Prevent the occurrence of leakage accidents.
