(1) First of all, it is necessary to find out what the leakage points of the device are, analyze their leakage direction, pressure and other factors, and draw the distribution diagram of the probe position at the same time. According to the severity of the leakage, it is divided into three levels: Ⅰ, Ⅱ, and Ⅲ. .
(2) According to the density of the leaking gas, combined with the air flow trend, it is integrated into a leaking three-dimensional flow trend chart, and an initial setting plan is made at the downstream position of its flow.
(3) According to specific factors such as the wind direction and airflow direction of the place, determine the direction of the flammable gas leakage if a large amount of leakage occurs.
(4) Investigate whether the leak state of the leak point is a slight leak or a spray pattern. If it is a slight leak, the location of the set point should be closer to the leak point. If it is sprayed, keep it away from the leak point. Considering these conditions comprehensively, the final setting plan is drawn up. In this way, it is possible to estimate the quantity and variety that need to be purchased.
