Principal usos i precaucions de fosa alumini escalfadors

1, The main uses of cast aluminum heaters are:

Àmpliament utilitzat en plàstic maquinària, motlles, cable maquinària, aliatge fosa a pressió màquines, canonades, productes químics, cautxú, petroli i altres equips.

2, Tècnic Característiques de fosa alumini escalfador:

Metal casting heaters use tubular electric heating elements as the heating element and are bent into shape. They are centrifugally cast into various shapes using high-quality metal alloy materials as the outer shell into the mold, including circular, flat, right angle, air-cooled, water-cooled, and other special shapes. After precision processing, it can closely fit the heated body, and the surface load of the cast aluminum heater can reach 2.5-4.5w/cm2, with a maximum working temperature of 300-450 degree ; The surface load of the cast copper heater can reach 3.5-5.{{10}}w/cm2, and the maximum working temperature is between 500-600 degree ; The surface load of the cast iron heater can reach 4.5-6.0w/cm2, and the maximum working temperature is between 550-700 degree . Metal casting heater is an efficient and uniform heat distribution heater made of metal alloy with excellent thermal conductivity, ensuring uniform hot surface temperature and eliminating hot and cold spots in the equipment. It has advantages such as long service life, good insulation performance, strong mechanical performance, corrosion resistance, and magnetic field resistance. Adding insulation devices to the external heat dissipation surface and sintering infrared radiation on the internal heat dissipation surface can save 35% of electricity consumption.

3, Precaucions per ús fosa alumini escalfadors:

1. El treball tensió shall not exced 10% de el valor valor; El relatiu humitat de el aire shall not exced 95%, and there shall be no explosiu o corrosiu gasos.

2. El cablejat part should be placed outside the heating layer and insulation layer, and the shell should be efectivament grounded; Avoid contact with corrosive, explosiu media, and water; The lead wire should be able to withstand the temperature and heating load of the wiring section for a long time, and excessive force should be evited when tightening the wiring screws.

3. El metall fosa escalfador should be placed in a dry place. If the insulation resistance is lower than 1M Ω due to long-term storage, it can be baked in an oven at around 200 degrees Celsius for 5-6} hours to restore normal operation. O reduce the voltage and heat it up until the insulation resistance is restored.

4. El metall fosa escalfador should be positioned and fixed adequat, and the effective heating area must be tightly attached to the heating body, and empty burning is strictly forbidden. When pols o contaminants are found on the surface, they should be promptly cleaned and reused to evitar affecting heat dissipation and shortening service life.

5. The magnesium oxide powder at the outlet of the electric heating tube should be protected from pollutants and moisture infiltration in the use site to prevent leakage accidents.
