Use gas leaks Alarms >Notes
When using a gas leak alarm, what are the special considerations that need our attention? Some people may be unfamiliar with this content, but today Xiaobian will come to talk to you. Once the gas leak alarm is installed in place, its position is not easy to change. The following points should be considered for specific applications:
1. Find out what possible leaks of the device to be monitored, analyze their leakage pressure, direction and other factors, and draw the probe position distribution map, according to the serious leak The degree is divided into three levels: I, II, and III.
2. According to the specific factors such as airflow direction and wind direction of the site, determine the leakage direction of toxic gas when a large number of leaks occur.
3. According to the density of the leaking gas (greater or smaller than air), combined with the trend of air flow, integrated into a three-dimensional flow trend of leakage, and made in the downstream position of its flow Initial set point scheme.
4. Study the leak status of the leak point is micro leak or spray.
5. For places where there is a large toxic gas leak, according to the relevant regulations, a detection point should be set every 10-20m.
6. For locations with hydrogen leaks, the detector should be installed above the leak point.
7. For media with a gas density greater than air, the detector should be installed on the lower surface below the leak point, and pay attention to the surrounding environment.
8. For the open toxic gas diffusion and escape environment, if there is no good ventilation conditions, it is easy to make the toxic gas content in a certain part of the air close to or reach The lower explosive concentration, these are safety monitoring points that cannot be ignored.
