style="text-indent:25px">高低溫試驗箱的一個為主機組，另一個為輔助機組，在降溫速率較大時，兩組機組同時工作，在溫度保持階段初期，兩組機組依然同時工作。待溫度初步穩(wěn)定下來，輔助機組就停止工作，由主機組來維持溫度的降溫及穩(wěn)定。如果主機組R23泄露，會使主機組的制冷效果不大，由于降溫過程中，兩機組同時工作，故沒有溫度穩(wěn)定不住的現(xiàn)象，而指示降溫速率降低。在溫度保持階段，一旦輔助機組停止工作，主機組又無制冷作用，高低溫試驗箱內(nèi)的空氣溫度就會緩慢上升，當(dāng)溫度上升到一定程度，控制系統(tǒng)就會又啟動輔助機組來降溫，然后輔助機組又停止工作，如此反復(fù)，便會出現(xiàn)低溫度保持不住的故障現(xiàn)象。杭州高低溫試驗箱價格高低溫試驗箱主要特點：采用原裝進口高感應(yīng)FastAIT監(jiān)控制冷系統(tǒng)，能將冷媒量作有效的控制管理。</p><div

style="text-indent:25px">高低溫試驗箱根據(jù)試驗方法與行業(yè)標(biāo)準(zhǔn)可分為“交變試驗”和“恒溫試驗”，兩種試驗方法都是在高低溫試驗箱的基礎(chǔ)上進行升級拓展，交變試驗箱是指可以一次性將需要做的高溫、低溫、時間設(shè)定在儀表參數(shù)內(nèi)，試驗箱會按照設(shè)定走程序，高低溫試驗箱就是在做一個固定的溫度，使試驗效果更接近自然氣候，模擬出更惡劣的自然氣候，從而使被測樣品的可靠性更高。顯示屏幕：采用進口溫濕度控制儀，P.I.D高精度控制，杜絕長期運行不穩(wěn)定現(xiàn)象；濕度為直觀顯示控制，摒棄原有溫濕度對照的缺陷。</p><p style="text-indent:25px">高低溫試驗箱的日常維護和對主要技術(shù)指標(biāo)的簡易測試，能夠保證高低溫試驗箱的工作處于較佳狀態(tài) 。以下，是幾點有關(guān)高低溫試驗箱維護保養(yǎng)需要注意的事項：一、高低溫試驗箱的溫度和濕度是影響儀器性能的重要因素，其可以引起機械部件的銹蝕，使金屬鏡面的光潔度下降，引起高低溫試驗箱機械部分的誤差或性能下降；造成高低溫試驗箱光學(xué)部件如光柵、高低溫試驗箱反射鏡、聚焦鏡等的鋁膜銹蝕，產(chǎn)生光能不足、雜散光、噪聲等，甚至儀器停止工作，從而影響高低溫試驗箱的壽命，維護保養(yǎng)時應(yīng)定期加以校正。二、高低溫試驗箱工作環(huán)境中的塵埃和腐蝕性氣體亦可以影響機械系統(tǒng)的靈活性、降低各種限位開關(guān)、按鍵、光電偶合器的可靠性，也是造成必須學(xué)部件鋁膜銹蝕的原因之一。三、高低溫試驗箱使用一定周期后，內(nèi)部會積累一定量的塵埃，高低溫試驗箱較好由維修工程師或在工程師指導(dǎo)下定期開啟高低溫試驗箱外罩對內(nèi)部進行除塵工作，同時將各發(fā)熱元件的散熱器重新緊固，對光學(xué)盒的密封窗口進行清潔，必要時對其進行校準(zhǔn)，對機械部分進行清潔和必要的潤滑，較后，恢復(fù)原狀，再進行一些必要的檢測、調(diào)校與記錄。高低溫交變試驗箱的安全常識：如高低溫試驗箱不配備加濕功能，閱讀說明時注意區(qū)別使用和要求上的不同。</p><div

style="text-indent:25px">高低溫試驗箱選購的時候請根據(jù)自身的試驗需求參考如下幾點： 1、溫度范圍：設(shè)備的溫度范圍多少，可以參考較高溫和較低溫數(shù)值。 2、循環(huán)功能：設(shè)備是否具有溫度循環(huán)功能，即為：溫度之間反復(fù)循環(huán)切換曲線循環(huán)。 3、濕度范圍：設(shè)備是否帶有濕度功能。 4、熱負載：很多測試的電子產(chǎn)品會進行通電測試，在通電的情況下，被測試的產(chǎn)品會發(fā)熱，這樣就會產(chǎn)生負載。所以有時候買回來的設(shè)備，如標(biāo)配是-20度，可是較后溫度降不下來，就是這個原因，所以一定要跟廠家說明負載情況。 5、設(shè)備搬運：請參考設(shè)備的外型尺寸，與設(shè)備較終安排位置情況，如門尺寸，樓梯電梯尺寸等。 6、電源：請參考設(shè)備的功率大小與較終安置的試驗室電源是否吻合或滿足。 7、設(shè)備工作室及外形尺寸。高低溫濕熱試驗箱加濕系統(tǒng)與加熱系統(tǒng)大致一樣，它是加熱器加熱水變成蒸汽過程，完成加濕目的。濕熱試驗箱供應(yīng)商</p><p
