Electric heating tube used in mechanical industry numerous equipments, we will often encounter some fundamental problems in the use of the process.Today, another big issue we explain the electric heating tube, the heating tube heating area is unbalanced, uneven. This situation will lead to no object can balance our heating heating area, not the result that we want. The factors below we have that happen in detail:
We have summarized the following 3 points:
1) to the resistance wire selection:
In the absence of production, we must first solve the very important step, select the good quality of the resistance wire. The resistance wire will directly affect the quality of the electric heating tube in use effect. Resistance wire is non-standard, from the appearance may not be see. But through the use of efficiency can be found, to select is low quality materials, conductive performance is not up to the effect, part of heating, heating effect of poor part, which leads to the non-uniform heating.
2) the resistance wire gap is not uniform:
In the choice of good resistance wire quality, we will make the process of silk. The resistance wire in accordance with design requirements, are elongated wound. This process as far as possible to ensure that the gap between the resistance wire of uniform, in electricity, in order to ensure uniform heating electric heating tube to the object, this process is very important.
3) magnesia powder filling improperly:
We all know that the electric heating tube filler interior general magnesia powder, and now many factories still use manual filling, this will result in the filling, can not grasp the internal elastic, tight part heating slowly, and too loose part heat faster, it will also cause the uneven heating.
