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。
The heat transfer oil heating pipe is a kind of heating pipe that consumes electric energy and converts it into heat energy to heat the materials to be heated. In the working process, the low-temperature fluid medium enters its input port under the pressure of the pipeline, taking away the high-temperature heat energy generated in the working process of the electric heating element, so as to raise the temperature of the heated medium. Along the specific heat exchange channel inside the electric heating container, when the heating element is over temperature, the independent overheat protection device of the heating element will cut off the heating power immediately, and the design is based on the principle of fluid thermodynamics The internal control system of the electric heater can automatically adjust the output power of the electric heater according to the temperature sensor signal of the output port, so as to make the medium temperature of the output port uniform, avoid coking, deterioration and carbonization caused by over temperature of the heating materials, and even burn out the heating elements in serious cases, so as to effectively extend the service life of the electric heating pipe.
