,單個排風試劑柜設計風量200m3/h ,原子吸收罩面風速:≥0.35 m/s ,排風量(350~ 600) m3/h。 3、通風系統(tǒng)使用終端噪聲≤60dB。4、整個通風系統(tǒng)均為中低壓系統(tǒng):75 Pa。5、系統(tǒng)風閥和風機整體連接,實現(xiàn)氣流的有序流動,平衡系統(tǒng)風量,防止氣流反串。6、通風系統(tǒng)及水電暢通無故障,管線、電路及部(配)件敷裝規(guī)范,連接可靠,無漏水、漏電現(xiàn)象。7、活性氧離子凈化空氣裝置,設備處理風量:≥10000CMH;電極發(fā)射管風管內風阻:≤30pa

1、通風柜面風速高于或低于0.5m/s都可能導致有害氣體外逸，過低的面風速無法有效捕捉排放的有害物質，過高的面風速導致通風柜內氣流形成紊流和渦流，同樣可能導致有害物質逸出。為確保排風效果，通風柜采用VAV變風量控制方式，要求通風柜面風速穩(wěn)定在0.5m/s±5%； 2、采用直接風速測量控制系統(tǒng)，能夠快速有效的保證通風柜面風速，從而達到保證實驗室工作人員安全的目的。為避免環(huán)境溫濕度對普通風速傳感器的基準點飄移影響，通風柜控制系統(tǒng)使用熱線型風速傳感器對面風速進行真實測量；風速傳感器配備獨特的自潔式過濾器，具有防灰塵堵塞功能；自然通風式通風柜無噪聲和振蕩；</p><div

style="text-indent:25px">通風柜的功能中較主要的是排氣功能，在化學實驗室中，實驗操作時產(chǎn)生各種有害氣體、臭氣、濕氣以及易燃、易爆、腐蝕性物質，為了保護使用者的安全，防止實驗中的污染物質向實驗室擴散，在污染源附近要使用通風柜，以往通風柜使用臺數(shù)較少，只在特別有害且危險的氣體及產(chǎn)生大量熱的實驗中使用。通風柜只擔負實驗臺的輔助功能?？紤]到改善實驗環(huán)境，在實驗臺上進行的實驗逐漸轉移到通風柜內，這就要求在通風柜里要有較適于設備使用的功能。特別是大多新建的實驗室都要求有空調，因此在建筑的初步設計階段就要將通風柜的使用臺數(shù)納入空調系統(tǒng)的計劃。由于通風柜在生化實驗室中占有非常重要的位置，從改善實驗室環(huán)境、改善勞動衛(wèi)生條件，提高工作效率等方面考慮，通風柜的使用臺數(shù)飛躍地增加。隨之而來的是通風管道，配管、配線、排風等都成為實驗室建設的重要課題。實驗室通風柜的材料由多種的，全鋼、鋼木、全木、鋁木、塑鋼、PVC結構等。寧波實驗室通風定做</p><p style="text-indent:25px">實驗室通風系統(tǒng)一般由通風設備、通風管道、消聲器、風機、控制系統(tǒng)組成。寧波實驗室通風定做</p><p style="text-indent:25px">通風柜控制系統(tǒng)的工作原理 1、變風量通風柜控制系統(tǒng)對通風柜每個時刻的排風量都進行了實時監(jiān)控與記錄，然后依據(jù)相關公式算出視窗的平均風速是多少，如果情況有變,控制系統(tǒng)會立即在1秒之內接收信號，將對風閥的開度進行調整，使視窗的開口面積平均風速保持到一個穩(wěn)定值，這一個數(shù)值需要在國家確定的范圍中。 2、根據(jù)進行的試驗情況的不同，在面板上可以設置相應的參數(shù)。如果有異常的狀況發(fā)生，控制系統(tǒng)就會接收信號，自動轉化為緊急排風狀態(tài),這時控制系統(tǒng)不受面風速值的影響，進行至大量的排風。寧波實驗室通風定做</p></p><br /><p>文章來源地址:
