Detection system and method for judging heating uniformity of electric heating tube

Abstract

The invention provides a detection system and a detection method for judging heating uniformity of electric heating tubes. The detection system comprises a bearing module, a power supply module, a detection module, a main control module and an alarm device. The bearing module comprises at least one electric heating tube support, and an electric heating tube is fixedly arranged on each electric heating tube support. The power supply module is electrically connected with the electric heating tubes. The detection module comprises a temperature sensing device and a magnetic field sensing device and is electrically connected with the power supply module, the temperature sensing device is used for detecting heat signals transmitted by different areas of the electric heating tubes when the electric heating tubes are electrified, and the magnetic field sensing device is used for detecting magnetic signals transmitted by different areas of the electric heating tubes when the electric heating tubes are electrified. The main control module is electrically connected with the power supply module and the detection module and is used for judging whether electric heating tubes are qualified or not according to detection results of the detection module. The alarm device is electrically connected with the main control module and is used for alarming when the main control module determines that the electric heating tubes are unqualified. The detection system and the detection method for judging heating uniformity of the electric heating tubes have the advantage that product reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of product quality inspection of electric heating tubes, in particular to a detection system and method for judging the heating uniformity of electric heating tubes. Background technique [0002] The heating uniformity of the metal tubular heating element is one of the important parameters reflecting the product quality and reliability of the heating element itself. However, the electric heating wire is unevenly wound, and the local heating of the pipe body is prone to uneven heating at places where the electric heating wire is too dense, which will accelerate the aging and deformation of the resistance wire (electric heating wire), and even "explode the tube" and burn it. Therefore, in order to ensure that the electric heater can operate normally with heat, so as to ensure the operation of the whole machine, and then ensure product quality and life reliability. It is necessary to ensure that the inner wire...
