In the field of chemical production, temperature control of cracking furnaces is crucial. The specialized thermocouple for Tiankang cracking furnace plays a crucial role as an efficient and accurate temperature sensor. It not only provides reliable data for temperature monitoring during the production process, but also ensures the stable and safe operation of the cracking furnace.

The working principle of the special thermocouple for Tiankang cracking furnace is based on the thermoelectric effect. It consists of two conductors with different compositions forming a closed circuit. When there is a temperature difference between the working end and the reference end of the thermocouple, a thermal current will be generated in the circuit. By measuring the magnitude of the thermal current and combining it with corresponding compensation wires and other supporting equipment, the temperature of the measured object can be accurately obtained. The specially designed protective tube closely adheres to the inside of the cracking furnace tube, which can quickly sense temperature changes without interfering with the normal flow of materials inside the furnace, ensuring the timeliness and accuracy of temperature measurement.

In order to maintain the good working condition of the special thermocouple for Tiankang cracking furnace, a scientific maintenance plan is essential.

In daily use, it is necessary to regularly inspect the appearance of thermocouples. Check if the protective tube is damaged or deformed, and if the connecting parts are loose. If any abnormalities are found, the machine should be shut down in a timely manner to avoid inaccurate temperature measurement caused by thermocouple failure, which may affect the normal operation of the cracking furnace.

Cleaning work is equally important. Due to the complex environment inside the cracking furnace, impurities and carbon deposits may adhere to the surface of the thermocouple. Regularly use appropriate cleaning tools and methods to remove these attachments to ensure the temperature sensitivity of the thermocouple. However, it should be noted to avoid mechanical damage to the thermocouple during the cleaning process.

Also pay attention to the electrical connections of thermocouples. Ensure that the connecting wires are in good contact and free from looseness or oxidation. Poor electrical connections can lead to unstable signal transmission and affect the accuracy of temperature measurement.

In addition, thermocouples should be calibrated according to the prescribed usage cycle. As the usage time increases, the performance of thermocouples may undergo certain changes. Through regular calibration, measurement errors can be detected and corrected in a timely manner to ensure their measurement accuracy.

The special thermocouple for Tiankang cracking furnace provides an effective solution for temperature measurement of cracking furnace with its unique working principle. By implementing a scientific maintenance plan, its service life can be further extended, ensuring stable production of the cracking furnace and laying a solid foundation for the efficient operation of chemical enterprises.
