The electric heating pipe is widely used in the industrial field and can be seen almost everywhere. Then, the manufacturers of electric heating coils come to talk with you about the application of the electric heating pipe in the industrial field.
And this kind of electric heating tube has been widely used in the industrial field. Its heating element is a selected alloy. The inherent thermal strain characteristics of its resistance value allow it to actively adjust the heating power, adjust the dynamic heating power according to the technical description of the temperature, heat the catalyst medium passing through the equipment pipeline, and then improve the activity of the catalyst. Can produce more types of goods and improve economic benefits.
However, this kind of electric heating pipe will also show different problems in the application process, so if you want to deal with the problem in time and make it operate normally, you must be proficient in the operating principle of this kind of electric heating pipe.
The following is a brief introduction to the working principle of the electric heating pipe: This electric heating element is a delta wiring, a temperature sensor is installed at the exit of the electric heating pipe, and the thermocouple is a temperature measuring element, the temperature can reach 800 degrees. The technical adjustment of the heating power is mainly performed by controlling the conduction angle of the triac in the voltage regulating module to complete the size of the output voltage of the voltage regulating module and then changing the power of the electric heating tube.
Technical requirements When starting the electric heating tube, open the power switch first, and ensure that the emergency stop point is closed. Under the premise of no fault alarm, press the start button to contact the contactor, and the upper end of the voltage regulating module is charged.
The medium temperature detection device can detect the medium temperature in the device. After the temperature signal is converted by the medium temperature transmitter to the current signal and sent to the emergency stop normally closed point, the electric heating tube will compare with the basic heating temperature signal set by the technology. The control signal is sent to the computer intelligent controller of the voltage regulator module, which controls the conduction angle of the triac to adjust the output voltage of the module and then change the power of the heater to reach the intention of controlling the temperature of the medium.
