Nowadays, with the continuous occurrence of many gas explosions in China, many places have carried out mandatory installation inspection on combustible gas alarms, requiring that combustible gas in public places, petroleum and petrochemical environments must be installed with combustible gas alarms that meet explosion-proof specifications. The correct installation directly determines the sensitivity and stability of the gas detector. Do you know what aspects should be considered when installing combustible gas alarm ? The following is a brief introduction by yi yun Tian:

Combustible gas alarm installation should consider the following aspects:

1. when using combustible gas alarm, it is necessary to find out the point where the equipment to be monitored may leak, analyze the leak pressure, direction and other factors, make the probe orientation distribution map, and divide it into 3 grades according to the severity of leak: 1. 2. 3.

2. judge the leakage direction of combustible gas when many leaks according to specific factors such as airflow direction and wind direction.

3. according to the density of the leaked gas (greater than or less than air) and the air activity trend, a three-dimensional activity trend chart of the leaked gas is synthesized, and an initial setting scheme is drawn up in the downstream direction of its activity.

4. to study the leakage status of the leakage point, the leakage status is still the eruption status. If it is a slight leak, the position of the set point of the combustible gas alarm should be close to the leak point. If it is an eruption leak, stay away from the leak point. Based on these circumstances, the establishment of a fixed point program. This allows you to estimate the quantity and variety that needs to be purchased.

5. for places with large leakage of combustible gas, the combustible gas alarm shall set up a detection point every 10-20m apart according to relevant regulations. On the unmanned duty of the small discontinuous pump room, should pay attention to the possible leakage of combustible gas. In general, should be in the air outlet equipment detector.

6. for media with gas density greater than air, the detector should be installed on the plane below the leakage point and pay attention to the characteristics of the surrounding environment. With regard to places where combustible gas is easy to accumulate, combustible gas alarms should pay special attention to setting up safety monitoring points.

7. regarding the dispersion and escape environment of open combustible gas, if there is no good ventilation condition, the combustible gas content in the air is very simple to approach or reach the lower limit concentration of blasting, which are all safety monitoring points that cannot be ignored.

In summary, these are some aspects that should be considered when installing a combustible gas alarm. Combustible gas alarm is the 1 kind of safety instrument, with sound, light display function, we should put the combustible gas alarm installed in the staff simply see and hear the local, in order to timely danger.
