W型电加热管, 金属管状电热元件原理
W type electric heating tube, the principle of metal tubular electric heating element
管状加热元件是一种在金属管中放入电阻丝,并在周围空隙部分紧密填充有良好耐热性、导热性和绝缘性的结晶氧化镁粉,再通过其他工艺处理的加热元件。它具有结构简单,机械强度高,热效率高,安全可靠,安装方便,使用寿命长凳特点。广泛用于各种硝石槽,水槽,酸碱槽及空气加热炉干燥箱,热模具等装置。用户在选择加热管的时候应考虑的是加热介质和使用环境,其余的由我们给您推荐最佳的设计方案。
Tubular heating element is a into the resistance wire in the metal tube, and in the surrounding void part tightly filled with good heat resistance, thermal conductivity and dielectric properties of crystalline magnesium oxide powder, and then through the other process heating element. It has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, convenient installation, service life bench characteristics. Widely used in a variety of niter slot, tank, acid-base tank and air heating furnace drying box, heat mold device. Consideration should be given to the user in the selection of heating tube is the heating medium and the use of the environment, the rest of us to recommend the best design.
它的原理如图
