電熱管受熱不均勻的原因

受熱不均勻的原因
The heat causes uneven
電熱管應用于眾多的機械行業設備中,我們在使用的過程中也會經常性的遇到一些根本性的問題。所以,這段時間我們一直在講述電熱管的一些基本參數及應用注意事項。今天,我們依舊在來解析下電熱管的另一大問題,那就是電熱管受熱面積不平衡,不均勻。發生這樣的情況會導致我們的物體發熱區不能平衡受熱,達不到我們想要的效果。下面我們就來詳細的講解下發生這種情況的因素:
Electric heating tube used in mechanical industry numerous equipments, we will often encounter some fundamental problems in the use of the process. So, this time we have been in some of the basic parameters about electric heating tube and application notes. Today, another big issue we still on to 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:
我們對此總結了以下3點:
We have summarized the following 3 points:
1)對電阻絲的選擇:
1) to the resistance wire selection:
在未生產時,我們要先解決很重要的一步,選擇質量好的電阻絲。電阻絲的好壞會直接影響到電熱管在使用時的效果。非標的電阻絲,從外觀上也許不能看出。但是使用時通過效率就可發現,選用的都是低品質的材料,導電性能就達不到效果,部分發熱好,部分發熱效果差,從而導致加熱不均勻。
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)電阻絲間隙不均勻:
2) the resistance wire gap is not uniform:
在選擇好的優質的電阻絲后,我們接下來就要進行打絲這一工序。就是將電阻絲按照設計要求,進行拉長纏繞。此過程盡量保證電阻絲之間的間隙均勻,在通電后,才能保證電熱管對物體均勻加熱,這道工序很重要。
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)氧化鎂粉填充不當:
3) magnesia powder filling improperly:
我們都知道電熱管內部的填充物一般為氧化鎂粉,而現在大多工廠依舊采用手工填充,這會導致在填充時,不能掌握好內部的松緊,過緊部分發熱會比較遲緩,而過松部分發熱較快,這樣也會導致加熱不均勻。
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.
