Application of electric heating tube in industrial field
Electric heating tubes are widely used in the industrial field and can be seen almost everywhere. So, heating tube manufacturers will come to talk with you about the application of electric heating tubes 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, and the thermal strain characteristics of its own resistance value enable 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 efficiency.
However, this kind of electric heating tube will also show different problems in the process of use, so if you want to deal with the problem in time and let it operate normally, you must master the operating principle of this kind of electric heating tube.
Here is a brief introduction to the operating principle of the electric heating tube: this electric heating element is a triangular connection, and a temperature sensor is installed at the outlet of the electric heating tube. The thermocouple is a temperature measuring element, and the temperature can reach 800 degrees. Technical adjustment of heating power: mainly through the control of the conduction angle of the triac in the voltage regulating module to complete the output voltage of the voltage regulating module and then change the power of the electric heating tube.
Technical requirements When starting the electric heating tube, first turn on the power switch and ensure that the emergency stop is closed. Under the premise that there is no fault alarm, press the starting button and the contactor to pull in, and the upper end of the voltage regulating module is charged.
The medium temperature detection equipment can detect the temperature of the medium in the equipment. After the temperature signal is converted into a current signal by the medium temperature transmitter and sent to the emergency stop normally closed point, the electric heating tube will be compared with the basic heating temperature signal set by the technology. The control signal is sent to the computer intelligent controller of the voltage regulating module to control the conduction angle of the triac to adjust the output voltage of the module and then change the heater power to achieve the intention of controlling the temperature of the medium.
