电伴热带功率选择错误隐患多

发布于:2017-06-08 13:18来源:安邦电伴热带 作者:电伴热带厂家点击:

选择电伴热带时,一定要注意功率的使用问题,错误的功率型号有可能导致不必要的后果。当冬季液体管道出现冻结现象时只需采用电伴热系统就可以轻松解决冻堵问题。由于用户接触到电伴热产品,很多时候只是了解到片面的一部分。可能会认为电伴热只有一种,只要可以保温就行。在这些用户的认知里对电伴热形成了误区,其实电伴热产品针对不同伴热场所有许多型号种类的电伴热产品。

虽然电伴热产品型号种类繁多,但其实确定好产品功率基本上就可以确定好哪种类型的产品了。

恒功率电伴热带
图示为恒定功率电伴热带,它的功率是不会变的

如自限温系列伴热带,它属于变功率产品,区别于其它电伴热产品,每米功率可因环境温度存在差异,一般国家标准定义自限温伴热带的功率,通常是指在10℃时输出功率。电伴热厂家所定义的功率是从温度角度出发来说,功率低的发热略慢,功率的高的发热略快。

伴热带在通电的那一瞬间,无论伴热产品是功率是多少启动电流都会变大,对于选用开关的变化都是一样的。因此若用户在选择自限温伴热带时,如果使用长度在100米左右,可以考虑使用自动限流器进行控制,以防出现问题。

当所伴热的设备出现功率过大时,管道可能会出现膨胀,导致爆裂现象的发生。那么为什么电伴热产品会出现这种现象呢?

其实最终导致温度过高,管道膨胀甚至差点发生爆裂现象的这一个问题的关键就在于用户选择电伴热产品时没有选出合适的电伴热产品,它的使用功率与现场所被伴热的设备要求不一致,所以造成了最终的问题。

对于还不太了解电伴热的用户,小编在这里需要申明下,电伴热产品种类繁多,相同的产品去还有不同的功率参数,因此在选型时需多注意这方面问题,这样就可以避免一些不必要的麻烦发生。
