Предпазни мерки за приложението на горими газови детектори
(1) Identify the potential leakage points to be monitored, analyze their leakage pressure, direction, and other factors, and draw a distribution map of probe positions. Classify them into three levels based on the severity of the leakage: Level I, Level II, and Level III.
(2) Въз основа на специфични фактори такива посока и вятър посока на местоположението, определяне посоката на запалим газ изтичане кога а голямо количество на на изтичането на.
(3) Based on the leakage (greater or less than), combined with the trend of air flow, a three-dimensional flow of leakage is synthesized, and an initial setting plan is made at the downstream position of its flow. Based on these situations, develop a final location plan. In this way, the quantity and variety that need to be purchased can be estimated.
4) For places with significant combustible gas leaks, a detection point should be set up every 10-20m according to relevant regulations. For unmanned small and discontinuous pump rooms, attention should be paid to the possibility of combustible gas leakage, and a detector should generally be installed at the lower air outlet.
(5) За местоположения с водород газ течове, детектори трябва бъде инсталиран на a плоска повърхност над теча точка.
(7) За медия с а газ плътност по-голяма от въздух, детекторът трябва бъде инсталиран на долната страна отдолу изтичането точка, и вниманието трябва заплащането на характеристики на заобикалящата среда Специално внимание трябва за... настройката на безопасността мониторинг точки в места къде запалими газове са склонни до до натрупване.
(8) For open environments where combustible gases diffuse and escape, if there is a lack of good ventilation conditions, it is also easy for the combustible gas content in a certain part of the air to approach or reach the lower explosive limit concentration. These are important safety monitoring points that cannot be ignored. According to the analysis of the on-site accidents, more than half of them were caused by incorrect installation and calibration. Therefore, it is necessary to introduce the precautions for correct installation and verification to reduce malfunctions
