If the heat in the electric heating tube is realized by the resistance wire, the resistance wire is spiral, and when the distance is different, it will heat differently, the distance is close, and the heat is high. vice versa. However, the quality of the process will also cause uneven heating of the electric heating tube. There are several main points, which I put together as follows:
1. The quality of the heating wire is not good, and the wire spacing is uneven after compression. It will directly lead to uneven heating of the heating tube, so manufacturers must purchase high-quality heating wires. Only in this way will we create a good quality and good quality brand.
Heater
2. Try to make the resistance wires evenly distributed during processing. Especially when winding the wire, it must be wound well. Otherwise, the heat will not be uniform.
3. Fill the electric heating tube with enough magnesium powder to make the filling in the tube dense, and then use a tube shrinking machine to compress it. (The phenomenon of unevenness caused by manual filling of magnesium powder and extrusion).
The above are several common methods for uneven heating of electric heating tubes. If you encounter uneven heating of electric heating tubes, you can refer to these three to make the simplest judgment. If these methods can be eliminated, you can directly call for consultation.
