Precautions and service life of cast aluminum heater!

Precautions for use of energy-saving heating ring cast aluminum heater:
A. The magnesium oxide powder at the outlet end of the electric heating pipe shall be protected from contamination and water penetration at the use site to prevent leakage accidents.
B. The wiring part shall be placed outside the heating layer and insulation layer, and the shell shall be effectively grounded; Avoid contact with corrosive and explosive media and water; The lead wire can bear the temperature and heating load of the wiring part for a long time, and avoid excessive force when fastening the wiring screw.
C. The metal casting heater should be placed in a dry place. If the insulation resistance of the energy-saving heating ring is lower than 1M Ω due to long-term storage, it can be baked in an oven at about 200 ℃ for 5-6 hours, and then it can return to normal. Or reduce the voltage and heat it until the insulation resistance is restored.
D. The working voltage shall 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.
E. The metal casting heater shall be well positioned and fixed. The effective heating area of the energy-saving heating ring must be closely connected with the heating body, and it is strictly prohibited to burn empty. When dust or pollutants are found on the surface, they should be cleaned and reused in time to avoid affecting the heat dissipation and shortening the service life.
