How to install a gas detector at a fixed point?
At present, with the rapid development of my country's industry, gas detectors have been widely used in real-time detection of the gas environment in the area to help us solve the problem of gas detection, thereby protecting people's lives. However, in order to ensure the reliability and accuracy of detection data, we need to install gas detectors at fixed points. So do you know how to install a gas detector at a fixed point? Fosensor will introduce it to you below.
Methods for fixed-point installation of gas detectors:
1. Find out what possible leak points the device to be monitored has, analyze their leak pressure, direction and other factors, and draw a probe location distribution map. According to the severity of the leak, it is divided into three levels: I, II and III.
2. Based on specific factors such as the airflow direction and wind direction of the location, determine the direction of flammable gas leakage when a large leakage occurs.
3. According to the density of the leaked gas (greater or smaller than air), combined with the air flow trend, a three-dimensional flow trend diagram of the leakage is synthesized, and an initial setting plan is made at the downstream position of its flow.
4. Study whether the leakage state of the leakage point is micro-leakage or spray-like. If it is a slight leak, the setting point should be closer to the leak point. If it is a spray leak, move slightly away from the leak point. Based on these conditions, a final set point plan is drawn up. In this way, the quantity and variety to be purchased can be estimated.
5. For places with large flammable gas leaks, gas detectors should be equipped with a detection point every 10-20m apart according to relevant regulations. For small, unattended and discontinuously operating pump rooms, attention needs to be paid to the possibility of flammable gas leakage, and a detector should generally be installed at the downdraft.
6. The gas detector is installed in an area where there may be gas leakage. The gas detector must be installed firmly, and the installation position is determined according to the specific gravity of the gas being measured relative to the air. Since the specific gravity of the gas being measured is smaller than that of air, c should be installed at a distance from the ceiling. At 30~60cm. Use φ8 expansion screws to fix the detector to the wall.
To sum up, this is how to achieve fixed-point installation of gas detectors. Under normal circumstances, if there are no unexpected circumstances, the gas detector should be installed in a place where gas is prone to leakage. The specific location should be determined according to the specific gravity of the detected gas relative to the air. When the specific gravity of the detected gas is greater than the specific gravity of air, the gas detector should be installed Just place it at a distance of (30-60)CM from the ground, with the gas sensor facing downwards.
