在線氫氣分析儀的維護要點

發布日期:2022-10-09 點擊率:67

   樣氣從采樣探頭進來后分2個支管,一支到放散管路,另一支經過采樣泵、 過濾器、冷卻器,然后分兩路分別進人氧氣分析儀及紅外分析儀,出來的氣體經過緩沖罐后 進行放散。 紅外分析儀用來分析C0、C02的成分。

   在線氫氣分析儀維護要點: 1) 排水:每天檢查冷凝器、汽水分離器、排水蠕動泵的狀態,確保流量計內無積水,如有 積水應查明原因并排除; 2) 流量調整: 進人分析儀的流量確保在1L/min,放散流量計的流量等于泵的額定流量減去進 人分析儀的流量; 3) 探頭:每2個月對探頭不銹鋼燒結濾芯進行清洗,并對采集管進行清灰除塵; 4) 濾芯、濾紙更換:霧過濾器濾芯應2月更換一次,高分子薄膜過濾器濾紙每周更換一次; 5) 標定:每3個月對氧分析儀和紅外線分析儀進行一次標定。
