What Issues Need to Be Considered When Installing a Combustible Gas Detector?
Combustible gas detector is a detector that responds to the concentration of single or multiple combustible gases. It should be installed in the areas of process equipment and storage facilities (including storage tank areas, loading and unloading facilities, filling stations, etc. for Class A gases and liquefied hydrocarbon liquids) that produce or use combustible gases, as well as in situations where combustible gases may be generated. So what issues should be considered when installing a combustible gas detector?
1. The combustible gas detector determines the direction of combustible gas leakage when a large amount of leakage occurs based on specific factors such as the direction of airflow and wind direction in the location.
2. Firstly, it is necessary to identify which areas of the device to be monitored may be leakage points or prone to gas leakage, such as pipeline interfaces, and analyze factors such as leakage pressure and direction.
3. Study whether the leakage state of the leakage point is micro leakage or jet like. If it is a minor leak, the location of the point should be closer to the leak point. If it is a jet leak, it should be kept slightly away from the leak point.
4. There should be no strong electromagnetic field (such as high-power motors or transformers) around the alarm controller that could affect the operation of the instrument.
5. Based on the density of the leaked gas (greater or less than air), combined with the trend of air flow, make an initial setting plan at the downstream position of its flow.
6. After installing the detector, it is necessary to install breathable waterproof and dustproof covers to prevent dust and rainwater from entering and damaging the installation of the detector controller.
