The role of cast aluminum heating ring

作者: Release Date: 2019-03-23 Author: Click:

The cast aluminum heating coil is one of the most important parts of the cast aluminum electric heater. The cast aluminum heating coil is the core of the cast aluminum electric heater. The working principle of the cast aluminum electric heater is that the current passes through the cast aluminum heating coil to generate heat. Therefore, the cast aluminum heating coil is the core of the core of the cast aluminum electric heater. The following briefly introduces the cast aluminum electric heater.


The cast aluminum electric heater is a tubular electric heating element with a heating element and a high-quality cast aluminum material as a shell. The electric heater is die-cast. Its operating temperature is generally between 150 and 300 degrees Celsius. It can be widely used in plastic machinery and molds. Head, cable machinery, chemical, rubber, petroleum and other equipment. Cast aluminum heater features long life, good thermal insulation performance, strong mechanical properties, corrosion resistance, anti-magnetic field and other advantages. This product has good heating performance and superior cooling performance. Guarantee the advantages of stable quality of processed products.


The cast aluminum electric heater is a high-efficiency heater with uniform heat division. A metal alloy with excellent thermal conductivity ensures a uniform hot surface temperature and eliminates hot and cold spots on the equipment. It has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance and anti-magnetic field. Increasing the heat dissipation device on the outer heat dissipation surface and sintering infrared rays on the inner heat dissipation surface can save electricity by 35%.


This series of heater products: the resistance wires are imported nickel-chromium wires and high-quality insulation materials. It has the characteristics of reasonable design, fine processing, precision, high thermal efficiency, energy saving, safety and reliability.


Use and maintenance:


1. First check whether the power supply voltage at the site of use matches the rated voltage of the product. If it is different, it should be equipped with the same power supply voltage as the rated voltage of the product.


2. In order to ensure safety, remember to reliably ground the enclosure of the electrical equipment.


3. When the electric heater is used for more than three months, it should be intermittently powered and dried by itself under the allowable conditions, and heated for ten minutes and stopped for half an hour, three to four times in a row to discharge the moisture inside the heating element.


4. The electric heater should be protected from moisture and corrosion during storage and stored in a well-ventilated place.


Instructions for use:


1) The working voltage must not exceed 10% of the rated value;


2) The wiring part is placed outside the heating layer and insulation layer, and the shell should be effectively grounded;


3) It should be placed in a dry place. If the insulation resistance is lower than 1MΩ for a long time, it can be baked in an oven at about 200 degrees Celsius for 5-6 hours to return to normal.


Cast copper electric heater is a tubular electric heating element with a heating element and a high-quality copper material as the shell. The electric heater is die-cast. Its operating temperature is generally between 150 and 450 degrees Celsius. It can be widely used in plastic machinery and die heads. , Cable machinery, chemical, rubber, petroleum and other equipment. The characteristics of cast copper electric heaters are long life, good thermal insulation performance, strong mechanical properties, corrosion resistance, anti-magnetic field, etc. The same size and power, the cost of cast copper is high, but the heat transfer is fast, the life is the same size. The highest power can be about 1.5-2 times the power of cast aluminum. The maximum temperature of copper is high and the temperature of aluminum is low.
