PTC伴热带油罐保温助生产

发布于:2017-03-15 16:07来源:安邦电伴热带 作者:电伴热带厂家点击:

PTC伴热带其实也是人们常说的“自控温伴热带”,目前已被广泛应用于炼油、油罐、储罐等领域,在冬季或者北方、西北部分地区,常年最低气温出于0度以下,时常会发生油罐或者储罐内溶液冷凝的现象,影响正常的生产使用,采用PTC伴热带可以有效解决这一难题。

那么为什么要使用PTC伴热带呢?

油罐自限温电热带由导电高分子复合材料(塑料)和两根平行金属导线及绝缘护套构成的扁形带状电缆。其特性是导电高分子复合材料具有正温度系数“PTC”特性,且相互并联,能随被加热体系的温度变化自动调节输出功率,自动限制加热的温度。“PTC”特性即正温度系数效应,是指材料电阻率随着温度升高而增大,并在一定温度区间电阻率急剧增大的特性。温控电热带可以任意截短或在一定范围内接长使用,并允许多次交叉重叠而无高温热点及烧毁之虑。因此温控电热带优点是:

油罐自限温电热带相应被伴热体系具有自动调节输出功率,因此不会因自身发热而烧毁,却因实际需要热量进行补偿,因此为新一代节能型恒温加热器。

油罐自限温电热带为油罐提供所需热量,使油温保持在含蜡原油和稠油的临界点之上。自调可变的输出功率使自控温电热带设计达到最佳的经济效益。

自控性能使油罐不会过热,不会产生过热点或由于井况的变化产生烧毁现象。自控温技术使电热带每一点相应因被伴热体系每一点温度变化而都能自调功率。随着油管温度的增加,电热带会自动地降低输出的热量,反之亦然。以此方式伴热电缆会不断地补偿温度的波动,而常规电热线(恒功率)易产生局部过热和烧毁等。

完美的PTC效应使得油罐保温的问题被有效解决,越来越多的石油、化工领域厂家选择安邦电气进行电伴热项目合作,安邦秉承服务至上,严抓质量的发展标准正在电伴热行业上不断前行。
