As we all know, combustible gas is the 1 kind of gas with flammable and explosive properties, which has a relatively high risk. Therefore, in order to better prevent the great harm caused by the leakage of combustible gas, we must install combustible gas alarm to monitor the concentration of combustible gas, which is an effective means to prevent gas accidents. However, if we better ensure the accuracy of combustible gas alarm detection, we must do a good job in the daily use of the relevant maintenance work. Do you know how to maintain the Combustible Gas Alarm ? The following is a brief introduction by yi yun Tian:

combustible gas alarm maintenance method:

1. Replace probe regularly

from the reliability consideration and practice, combustible gas alarm system used for more than 5 years due to the aging of components caused by the failure tends to increase, so the service period exceeds the requirements of the use, should be replaced in a timely manner.

2. Clean the probe regularly

through the probe to detect combustible gas information, the probe must be communicated with the detection environment, so it is inevitable that all kinds of polluting gases and dust in the environment enter the inside of the probe protective cover. The damage to the working conditions caused by the probe objectively exists. The working environment of the combustible gas alarm detection head is relatively harsh, and many of them are installed outdoors. Poor maintenance will lead to errors or non-detection of combustible gas alarm detection. Therefore, regular cleaning of the interior of the probe protective cover of the combustible gas alarm is the fundamental guarantee to ensure the accuracy of the detection data.

3. Regularly check grounding

combustible gas alarm grounding fail to meet the requirements of the standard, or not grounded at all, it will also make the combustible gas alarm electrical signal susceptible to electromagnetic interference, resulting in inaccurate detection data or other equipment failures.

4. Regularly calibrate zero and span

zero point, span value, for the combustible gas alarm with zero point and range drift, the standard gas should be calibrated in time or the value should be adjusted by the controller to ensure that the combustible gas alarm operates under normal conditions.

In summary, it is the maintenance method of combustible gas alarm. In addition, when we use the combustible gas alarm, we should also try to use the combustible gas concentration below the lower explosive limit, otherwise, it may burn out the components.
