The use and maintenance of cast aluminum heater
1.Check whether the power supply voltage at the use site is consistent with the rated voltage of this product. If it is different, it should be equipped with the same power supply voltage as the rated voltage of this product.
2. To ensure safety, remember that the shell of the electrical equipment must be grounded reliably.
3. When the electric heater is used for more than three months, it should be energized intermittently and self-dried under permissible conditions, heating for ten minutes, power outage for half an hour, three to four consecutive times to drain 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 shall 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 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 .
The cast copper electric heater is a tubular electric heating element as the heating element, and the high-quality copper material is used as the shell to form an electric heater. 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 have the advantages of long life, good 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 long, the same size, the same size, cast copper The highest power can be about 1.5-2 times the power of cast aluminum. The high temperature of copper is high, and the temperature of aluminum is low. The above is the relevant content introduced to you by the cast copper heater, I hope it will be helpful to you.
