受热不均匀的原因
The heat causes uneven
电热管应用于众多的机械行业设备中,我们在使用的过程中也会经常性的遇到一些根本性的问题。所以,这段时间我们一直在讲述电热管的一些基本参数及应用注意事项。今天,我们依旧在来解析下电热管的另一大问题,那就是电热管受热面积不平衡,不均匀。发生这样的情况会导致我们的物体发热区不能平衡受热,达不到我们想要的效果。下面我们就来详细的讲解下发生这种情况的因素:
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:
我们对此总结了以下3点:
We have summarized the following 3 points:
1)对电阻丝的选择:
1) to the resistance wire selection:
在未生产时,我们要先解决很重要的一步,选择质量好的电阻丝。电阻丝的好坏会直接影响到电热管在使用时的效果。非标的电阻丝,从外观上也许不能看出。但是使用时通过效率就可发现,选用的都是低品质的材料,导电性能就达不到效果,部分发热好,部分发热效果差,从而导致加热不均匀。
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)电阻丝间隙不均匀:
2) the resistance wire gap is not uniform:
在选择好的优质的电阻丝后,我们接下来就要进行打丝这一工序。就是将电阻丝按照设计要求,进行拉长缠绕。此过程尽量保证电阻丝之间的间隙均匀,在通电后,才能保证电热管对物体均匀加热,这道工序很重要。
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)氧化镁粉填充不当:
3) magnesia powder filling improperly:
我们都知道电热管内部的填充物一般为氧化镁粉,而现在大多工厂依旧采用手工填充,这会导致在填充时,不能掌握好内部的松紧,过紧部分发热会比较迟缓,而过松部分发热较快,这样也会导致加热不均匀。
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.
