Combustible gas alarm is an important safety monitoring gas detection instrument for enterprise safety production. Its main function is to detect the concentration of combustible gas in the air. When the concentration in the air reaches a certain concentration, the combustible gas alarm will automatically sound and light alarm to remind the staff to take corresponding measures in time to avoid major accidents. So do you know what to do if there is a problem with the value of combustible gas alarm ? The following is a brief introduction by yi yun Tian:

combustible gas alarm value problem handling method:

The fault 1. display has large numerical error

Part of the reason for this failure is that the combustible gas alarm probe has not been effectively calibrated for a long time, as a result, the sensitivity of the sensor is greatly reduced, resulting in inaccurate measurement results of hydrogen sulfide gas concentration.In addition, according to the analysis of drilling site operation, combustible gas alarm probes are mainly distributed at the wellhead, drill floor and other positions, which makes its surface and gas flameproof membrane easy to be polluted by mud and drilling fluid, in addition, the flameproof membrane is also easy to be soaked by rain in rainy weather. These are combustible gas alarm can cause error.

Processing method:

1. Regularly check the use of the probe and clean the flameproof membrane regularly; regularly calibrate the sensor.

2. Install a rainproof device for the probe installed in the open air.

failure 2. no indication

the reason is that the flameproof plate of the combustible gas alarm sensor is blocked or the sensor fails, make the combustible gas alarm system in a paralyzed state.

Handling:

1. If there is no indication due to the blockage of the flameproof sheet, we can first remove the probe, remove the metal flameproof sheet, soak the filter membrane in water with a small amount of detergent for about half an hour, and then brush off the dirt with a brush; clamp the flameproof plate with pliers, blow and wash the filter membrane repeatedly with a high-pressure air gun, and install it after drying.

2. If the sensor fails, we can directly replace the sensor of the combustible gas alarm.

To sum up, this is the way to deal with the problem with the value of the combustible gas alarm. If you want to know more about the oxygen detector, you can come to Yiyuntian for consultation. We have professional personnel to answer for you.
