水管道电加热器结构 水管道电加热器是由多支管状电加热元件、筒体、导流板等几部分组成,管状电热元件是在金属管内放入高温电阻丝,在空隙部分紧密地填入具有良好绝缘性和导热性能的结晶氧化镁粉,采用管状电热元件做发热体,具有结构先进,热效率高,机械强度好,耐腐、耐磨等特点。筒体内安装了导流隔板,能使水在流通时受热均匀。 (2)工作原理 水管道电加热器采用数显温度调节仪、固态继电器和测温元件组成测量、调节、控制回路,在电加热过程中测温元件将水管道电加热器出口温度电信号送至数显温度调节仪进行放大,比较后显示测量温度值,同时输出信号到固态继电器输入端,从而控制加热器,使控制柜具有良好的控制精度和调节特性。利用联锁装置可远距离启动、关闭水管道电加热器。Water pipes water pipes electric heater electric heater structure is a multi-branched tubular electric heating elements, cylinder, deflector composed of several parts, tubular heating elements are placed in the metal tube high temperature resistance wire, tightly fill in some gaps into with good insulation and thermal conductivity crystalline magnesium oxide powder, used to make heating element tubular heating elements, advanced structure, high thermal efficiency, good mechanical strength, corrosion resistance, wear characteristics. Install the deflector baffle cylinder body, make the water flow when the heat evenly. (2) the working principle of water pipe electric heater with digital temperature regulator, solid state relays and temperature components measuring, regulating, control loops, process temperature in the electric heating element electric heater water pipe outlet temperature signal sent digital temperature regulator to amplify comparison shows the measured temperature value, while the output signal to the input terminal of solid state relays to control the heater, the control cabinet has good control accuracy and regulation characteristics. Using the interlock device can be remote start, shut down the water pipes electric heater.
