In order to more standardize the order of the electric heating element market, improve the safety of the electric heating tube. This is not only what users expect, but also what many manufacturers want. The heating wires in the electric heating tubes produced are all made of core grinding equipment, and the tube diameter is highly standardized. It is closely coordinated with the equipment assembly. The specifications of the electric heating tube are produced, and the user buys it and installs and uses it, which cannot achieve the expected effect. Therefore, the technical indicators and parameters of the electric heating tube can provide people with a convenient reference when purchasing an electric heating tube. The stable operation of the electric heating tube can better improve the use of the equipment.
The unit power of the surface area of the heating zone of the electric heating tube:
Pipe diameter load value (Wcm square)
φ6～φ10 ≤22
φ10.1 ～φ14 ≤20
φ14.1～φ18 ≤16
φ18.1～φ22 ≤12
φ22.1～φ40 ≤10
The above surface load generally means that it can be multiplied by 2 to 2.5 when combined with metal mold heating and water heating. Air heating is 50% to 60%.
The main parameters of the electric heating tube:
1. Power supply voltage, V;
2. Power frequency, Hz;
3. Rated voltage, V;
4. Rated power, kw;
5. Working temperature, ℃;
6. Outer diameter, (diameter of the die of the single-head electric heating tube), mm;
7. Expanded length, mm;
8. Overall dimensions, mm;
9. Weight, kg.
