小型恒溫恒濕機日常維護與濾網更換周期建議
2025-12-13

小型恒溫恒濕機廣泛應用于實驗室樣品保存、醫藥存儲、電子元器件測試、文物養護等對環境溫濕度敏感的場景。其穩定運行不僅依賴精密的制冷/加濕系統,更離不開科學的日常維護。忽視保養,輕則導致控溫控濕精度下降,重則引發設備故障甚至樣品損毀。其中,濾網...

    實驗室恒溫恒濕機的維護要點:1.由于溫(濕)度箱價值一般都比較高,我們建議將其置于比較良性溫度環境中,我們的經驗溫度值為8℃~23℃,對不具備此條件的實驗室,須配備適當的空調器(風冷)或冷卻塔(水冷)。2.堅持專人專業管理。有條件的單位,應不定期派專人到供方工廠培訓學習,以獲得較專業的維護、維修經驗和能力。3.定期(每3個月)清洗冷凝器:對于壓縮機采用風冷冷卻的,應定期檢修冷凝風機,并對冷凝器進行去污除塵,以保證其良好的通風換熱性能;對于壓縮機采用水冷冷卻的,除須保證其進水壓...

    2020年,一場疫情在蔓延,給人們的生活按下了暫停鍵。目前,中國地區抗擊病毒戰役取得階段性的勝利,截止發稿前中國累計治愈74744人,全國大部分地區確診、疑似多日保持零增長。但海外地區疫情仍屬于高爆發期。抗疫是*的責任,中國作為擔當大國,持續在對外分享經驗,派送醫療專家組以及調撥醫療物資,決心與人民攜手戰勝病毒。中國在控制疫情方面取得了顯著的效果,主要歸功于果斷封城,在全國范圍內貫徹落實“早隔離、早發現、早收治”的防控方針。在防疫抗疫過程中,不聚堆,不走動,佩戴,很大程度的杜...

    使用萬用表時應注意的事項1、每次測量前應把萬用表水平放置,觀察指針是否指零,指針不指零時用旋具微微調整表頭的機械零點螺釘,使指針指零。2、紅、黑色表筆應正確插入萬用表插孔。旋轉拔子旋鈕應放置在所要測量電參量的量程擋上,決不可誤放。3、如果不清楚所測電壓、電流值的大概范圍,應首先用表上的大電壓擋、大電流擋預測,然后再改用適當的量程測量。4、如果不清楚被測電路的正、負極性,可將轉換拔子旋鈕放在高擋,測量時用表筆輕輕碰一下被測電路,同時觀察指針的偏轉方向,從而確定出電路的正、負極。...
