臭氧老化在線試驗箱 臭(chou)氧(yang)老化(hua)試(shi)驗(yan)(yan)箱(xiang)(xiang)由無聲高效臭(chou)氧(yang)發(fa)(fa)生器(qi)(qi)(qi)發(fa)(fa)生的臭(chou)氧(yang)氣(qi)體，和(he)一定量的已處理的空氣(qi)，在交換器(qi)(qi)(qi)中混合后(hou)送(song)入試(shi)驗(yan)(yan)箱(xiang)(xiang)，紫外(wai)檢(jian)測(ce)儀將連續在線檢(jian)測(ce)到(dao)的臭(chou)氧(yang)濃度，反饋到(dao)臭(chou)氧(yang)發(fa)(fa)生器(qi)(qi)(qi)控制(zhi)系(xi)(xi)統，使控制(zhi)系(xi)(xi)統根據設定值有(you)效的控制(zhi)臭(chou)氧(yang)的發(fa)(fa)生，從而試(shi)驗(yan)(yan)箱(xiang)(xiang)保持(chi)設定的臭(chou)氧(yang)濃度，另由加熱加濕系(xi)(xi)統工(gong)作(zuo)，滿足所有(you)的試(shi)驗(yan)(yan)條件。臭(chou)氧(yang)老化(hua)試(shi)驗(yan)(yan)箱(xiang)(xiang)適用(yong)于測(ce)試(shi)硫(liu)化(hua)橡膠制(zhi)品、有(you)機材料、非金屬材料的耐(nai)臭(chou)氧(yang)老化(hua)性能和(he)老化(hua)龜(gui)裂拉伸試(shi)驗(yan)(yan)。 試驗方法 根據(ju)試(shi)驗(yan)方法(fa)及標準可分為“靜態(tai)”和“動(dong)態(tai)”，靜態(tai)是指樣品被拉(la)伸好后放放試(shi)驗(yan)箱(xiang)做測試(shi)，動(dong)態(tai)則是把樣品放置(zhi)在試(shi)驗(yan)箱(xiang)的夾具上，邊(bian)拉(la)伸邊(bian)做試(shi)驗(yan)，拉(la)伸的浮動(dong)為被測樣品本身(shen)的5%-45%左右(you)。 臭氧老化在線試驗箱 制冷配置與原理、
1、制冷系統及壓縮機：為了保證試驗箱對降溫速率和低溫度的要求， 本試驗箱的制冷系統采用進口壓縮機所組成的復疊式制冷系統，該制冷系統具有匹配合理、可靠性高、使用維護方便等優點
2、制(zhi)(zhi)(zhi)冷(leng)(leng)工作原(yuan)理：制(zhi)(zhi)(zhi)冷(leng)(leng)循(xun)環均采用(yong)(yong)逆卡若循(xun)環，該(gai)循(xun)環由(you)兩(liang)個等(deng)溫(wen)(wen)(wen)(wen)過(guo)程和兩(liang)個絕熱過(guo)程組成(cheng)，其過(guo)程如下：制(zhi)(zhi)(zhi)冷(leng)(leng)劑(ji)經(jing)壓縮機(ji)絕熱壓縮到較高(gao)的(de)(de)壓力，消耗了(le)功(gong)使(shi)排(pai)氣溫(wen)(wen)(wen)(wen)度升高(gao)，之(zhi)后制(zhi)(zhi)(zhi)冷(leng)(leng)劑(ji)經(jing)冷(leng)(leng)凝器(qi)等(deng)溫(wen)(wen)(wen)(wen)地和四周介(jie)質進行(xing)(xing)(xing)熱交換將(jiang)熱量(liang)傳給四周介(jie)質。后制(zhi)(zhi)(zhi)冷(leng)(leng)劑(ji)經(jing)截流閥絕熱膨脹做功(gong)，這時(shi)制(zhi)(zhi)(zhi)冷(leng)(leng)劑(ji)溫(wen)(wen)(wen)(wen)度降低。后制(zhi)(zhi)(zhi)冷(leng)(leng)劑(ji)通過(guo)蒸發器(qi)等(deng)溫(wen)(wen)(wen)(wen)地從溫(wen)(wen)(wen)(wen)度較高(gao)的(de)(de)物體吸熱，使(shi)被冷(leng)(leng)卻物體溫(wen)(wen)(wen)(wen)度降低。此循(xun)環周而(er)復始(shi)從而(er)達(da)到降溫(wen)(wen)(wen)(wen)之(zhi)目的(de)(de)。制(zhi)(zhi)(zhi)冷(leng)(leng)系(xi)統(tong)的(de)(de)設計應用(yong)(yong)能量(liang)調(diao)節(jie)技術，一(yi)種行(xing)(xing)(xing)之(zhi)有效(xiao)的(de)(de)處理方式(shi)既能保證(zheng)在制(zhi)(zhi)(zhi)冷(leng)(leng)機(ji)組正常(chang)運行(xing)(xing)(xing)的(de)(de)情況下又能對(dui)制(zhi)(zhi)(zhi)冷(leng)(leng)系(xi)統(tong)的(de)(de)能耗及制(zhi)(zhi)(zhi)冷(leng)(leng)量(liang)進行(xing)(xing)(xing)有效(xiao)的(de)(de)調(diao)節(jie)，使(shi)制(zhi)(zhi)(zhi)冷(leng)(leng)系(xi)統(tong)的(de)(de)運行(xing)(xing)(xing)費(fei)用(yong)(yong)下降到較為經(jing)濟(ji)的(de)(de)狀下 制(zhi)(zhi)冷系(xi)(xi)統(tong)(tong)及壓(ya)縮機(ji)：為了(le)保(bao)證試驗(yan)箱(xiang)對降溫速率(lv)溫度的(de)(de)要(yao)求， 本(ben)試驗(yan)箱(xiang)的(de)(de)制(zhi)(zhi)冷系(xi)(xi)統(tong)(tong)采用進口壓(ya)縮機(ji)所(suo)組成的(de)(de)復疊式制(zhi)(zhi)冷系(xi)(xi)統(tong)(tong)，該制(zhi)(zhi)冷系(xi)(xi)統(tong)(tong)具有匹(pi)配合理、可靠性(xing)高、使用維護方便等優點 |
