Do you know the maintenance content of the UV flame detector?

Today, the editor brings you the maintenance content of the UV flame detector. If you don't know yet, take the time to learn about it!

During the detection of natural gas, gasoline, and diesel combustion by UV flame detectors, it is likely that the combustion of natural gas, gasoline, and diesel will emit pollutants, causing the quartz lens inside the UV probe of the UV flame detector to become sticky and dirty, affecting the power acceptance of the UV signal in the flame by the UV probe, resulting in reduced sensitivity. Therefore, in order to ensure the normal operation of the UV probe, it is necessary to regularly (depending on the application) scrub the lens of the probe, Keep clean and transparent.

2. At the end of the sensor's service life, the sensitivity will significantly decrease. Therefore, after using the sensor for a period of time, Xuzhou Jieneng Power Equipment Co., Ltd. introduced that if it is found that the sensor sensitivity cannot meet the specific requirements, it is necessary to regularly replace the UV probe.

3. Invisible flames:

(1) Check whether there is a problem with the switching power supply system;

(2) Check whether there is a problem with the connection between the probe and the control module;

(3) Check whether the probe photosensitive tube is intact and whether the monitored flame is within the efficient visual angle range of the sensor. The inspection method is as follows:

First, observe whether the photosensitive tube housing is cracked and whether the electrical level of the inner structure of the photosensitive tube is damaged. When ensuring that the above is intact, replace the photosensitive tube with a better probe and carry out the inspection. If the operation is normal, it indicates that the photosensitive tube is intact. On the contrary, the photosensitive tube is damaged and needs to be repaired in a timely manner.

Adjust the angle of view of the sensor by looking at it so that the flame can be within a reasonable angle of view of the probe.

4. Misreporting: Check whether the working power supply is too high, whether there is a short circuit fault in the power line, and whether there are interference signals such as arc welding stored on the spot.
