What issues should be noted when selecting electric heat tracing belts
电伴热带有两种类型:一种是自限型,即可变电阻加热带。功率是可变的,并达到自限温度。另一种是恒温型,它是一种恒阻加热带,功率稳定,可以实现恒温。那么电伴热带的选择方法是什么呢?
一般情况下,加热带的耐温等级和加热等级可以根据管道维护温度和意外高运行温度进行选择。根据管道可能承受的温度,选择相应的电伴热电缆型号。
水箱、水管等常用物品通常远离防爆区域,伴热元件浓度较低,温度控制要求较低。只要将水温保持在一定范围内,就可以满足设计要求。它可以使用自限位电伴热带,可以自动控制温度,无需配电箱和温控器等电加热附件。在阀门弯曲较多的区域,也可以实现交叉重叠安装。
在选择电伴热带时,用户还需要在现场确认自己能够承受的功率,然后根据功率选择相应的电伴热带。他们也可以选择恒功率电伴热带,因为它的功率是恒定的,不会随着外部和环境的变化而变化。它的功率总是恒定的,并且在启动过程中不会显示出过大的功率。
此外,在选择方面,需要考虑其伴热距离、防腐绝缘要求以及是否用于防爆场合。只有结合应用方法,才能确定电伴热带的正确选择方法。在选择电伴热带类型时,用户可以提供现场参数,让电加热制造商选择合适的电伴热带进行现场使用。
