Combustible gas is a 1 kind of substance that can be ignited and is in a gas state at normal temperature and pressure. Once the concentration is too high, it will cause harm to the environment or human body. The online combustible gas alarm is the 1 kind of security instrument that must be used to detect combustible gas. It can measure the concentration of combustible gas in the ambient air. When the concentration of combustible gas in the air reaches a certain amount, it will automatically alarm, and then make the exhaust or stop valve action response to prevent fire and poisoning accidents. In the working process of combustible gas alarm , due to various reasons, it is usually affected by some factors. then impact what are the factors for the normal operation of the online combustible gas alarm ? The following is a brief introduction by yi yun Tian:

The factors that affect the normal operation of the online combustible gas alarm are as follows:

1. non-corrosive flux must be used for welding of online combustible gas alarm, otherwise corrosion at the joint will disengage or increase the line resistance, thus affecting normal detection.

2. Do not drop or throw the online combustible gas alarm to the ground. In order to ensure that the online combustible gas alarm is in normal working state, it should be debugged in time after construction.

3. in order to ensure the safety of online combustible gas alarm construction and the sensitivity of application, if the gas installed on site is not grounded, electromagnetic interference cannot be eliminated, and the fault of inaccurate detection data will inevitably occur. therefore, the online combustible gas alarm should be reliably grounded during construction.

4. the gas alarm controller cannot have strong magnetic and electric interference on site. if there is strong magnetic and electric interference, the measurement data will also be inaccurate.

5. the online combustible gas alarm also has a certain range of environmental requirements. usually, the working environment requires the temperature range to be controlled at (0-40)℃; The relative humidity is 85% RH.

In summary, there are some factors that affect the normal operation of the online combustible gas alarm. In the process of using the online combustible gas alarm, we must remember that our explosion-proof facilities are damaged, such as explosion-proof seal damage, looseness, explosion-proof flexible tube rupture, fastening bolt looseness, explosion-proof threading box rupture, when these situations occur, Must be repaired or replaced in time.
