Application of mold heating tubes in the industrial field

Electric heating tubes are widely used in the industrial field and can be seen almost everywhere. So, today, Keda will talk to 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 an alloy selected. The thermal strain characteristics of its own resistance value can enable it to automatically adjust the heating power. According to the technical description temperature, the dynamic heating power is adjusted to heat the catalyst medium passing through the equipment pipeline, thereby improving the activity of the catalyst, and being able to produce more types of products and improve economic benefits. However, this type of electric heating tube will also have different faults during use, so if you want to deal with the faults in time and make it operate normally, you must be proficient in the working principle of this type of electric heating tube. The following is a brief introduction to the working principle of the electric heating tube: This electric heating element is a triangle wiring, and a temperature sensor is provided at the outlet of the electric heating tube. The thermocouple is a temperature measuring element, and the temperature can reach up to 800 degrees. The technical adjustment of heating power is mainly achieved by controlling the conduction angle of the bidirectional thyristor in the voltage regulating module to achieve the size of the output voltage of the voltage regulating module and then change the power of the electric heating tube. When the technical requirements start the electric heating tube, first turn on the power switch and make sure that the emergency stop point is in a closed state. Under the premise of no fault alarm, press the start button contactor to close, and the upper end of the voltage regulating module is energized. The medium temperature detection device can detect the medium temperature in the device. The medium temperature transmitter converts the temperature signal into a current signal and sends it to the emergency stop normally closed point. After comparing it with the basic heating temperature signal set by the technology, the electric heating tube sends the control signal to the computer intelligent controller of the voltage regulating module, controls the conduction angle of the bidirectional thyristor, adjusts the output voltage of the module, and then changes the power of the heater to achieve the purpose of controlling the medium temperature.
