导热油加热管是一种消耗电能转换为热能，来对需加热物料进行加热。在工作中低温流体介质通过管道在压力作用下进入其输入口，带走电热元件工作中所产生的高温热能量，使被加热介质温度升高，沿着电加热容器内部特定换热流道，当发热元件超温时，发热元件的独立的过热保护装置立即切断加热电源，运用流体热力学原理设计的路径，电加热器出口得到工艺要求的高温介质，电加热器内部控制系统依据输出口的温度传感器信号自动调节电加热器输出功率，使输出口的介质温度均匀，避免加热物料超温引起结焦、变质、碳化，严重时导致发热元件烧坏，有效延长电加热管使用寿命。

Heat conduction oil heating pipe is a kind of electric energy conversion to heat energy, to heat the heating material. In the work of low temperature fluid through a pipe under pressure into the input port, take away heat energy generated by electric heating element in the work of the heating medium temperature along the electric heating container specific heat flow, when the heating element overheating, overheating protection device independent of the heating element immediately cut off the heating power, using the path fluid thermodynamics principle design, electric heater exports have high temperature medium for the process of the internal control system of electric heater electric heater according to automatically adjust the output power of the temperature sensor signal output port, the output port of the medium temperature uniformity, avoid heating material overheating caused by coking, metamorphism, carbonization, leading to serious the heating element burned, prolong the service life of the electric heating tube.
