冷熱沖擊試驗機

冷熱沖(chong)擊試驗(yan)機是金屬、塑(su)料、橡膠(jiao)、電子等材料行業必備(bei)的測試設備(bei)， 用于(yu)測試材料結構(gou)或(huo)復合材料，在瞬間(jian)下經極高溫及極低溫的連續環境下所能忍受的程度，得(de)以在較短時間(jian)內(nei)檢測試樣因熱脹冷縮所引(yin)起的化(hua)學(xue)變(bian)化(hua)或(huo)物(wu)理(li)傷害。分為(wei)兩廂式和三廂式，熱流儀采購，區別(bie)在于(yu)試驗(yan)方式和內(nei)部(bu)結構(gou)不同，產(chan)品符合標(biao)準(zhun)為(wei)：GB/T2423.1-2008試驗(yan)A 、GB/T2423.2-2008試驗(yan)B、GB-T10592-2008、GJB150.3-198、GJB360A-96方法107溫度沖(chong)擊試驗(yan)的要求。

冷熱沖擊試驗箱工作原理

三箱式

內置預冷區、預熱(re)區、試驗(yan)(yan)區三(san)個(ge)部分，三(san)個(ge)區分別獨(du)立，三(san)個(ge)箱(xiang)體間(jian)通過(guo)風(feng)門(men)切換(huan)不需移動試驗(yan)(yan)產(chan)品，青(qing)海(hai)熱(re)流儀(yi)，沖(chong)(chong)擊(ji)常溫(wen)(wen)(wen)(wen)(wen)時(shi)(shi)，高(gao)(gao)低(di)(di)溫(wen)(wen)(wen)(wen)(wen)熱(re)流儀(yi)價位(wei)，通過(guo)鼓風(feng)機，把環境溫(wen)(wen)(wen)(wen)(wen)度導入試驗(yan)(yan)空間(jian)，排除(chu)試驗(yan)(yan)空間(jian)熱(re)量(liang)或冷量(liang)，同時(shi)(shi)高(gao)(gao)低(di)(di)溫(wen)(wen)(wen)(wen)(wen)槽(cao)(cao)風(feng)門(men)關(guan)閉(bi)；沖(chong)(chong)擊(ji)低(di)(di)溫(wen)(wen)(wen)(wen)(wen)時(shi)(shi)，高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)和(he)(he)常溫(wen)(wen)(wen)(wen)(wen)槽(cao)(cao)風(feng)門(men)關(guan)閉(bi)，低(di)(di)溫(wen)(wen)(wen)(wen)(wen)槽(cao)(cao)與(yu)試驗(yan)(yan)箱(xiang)相通，瞬(shun)間(jian)把預存(cun)冷量(liang)導入試驗(yan)(yan)箱(xiang)；沖(chong)(chong)擊(ji)高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)時(shi)(shi)，低(di)(di)溫(wen)(wen)(wen)(wen)(wen)和(he)(he)常溫(wen)(wen)(wen)(wen)(wen)槽(cao)(cao)風(feng)門(men)關(guan)閉(bi)，高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)槽(cao)(cao)與(yu)試驗(yan)(yan)箱(xiang)相通，瞬(shun)間(jian)把預存(cun)熱(re)量(liang)導入試驗(yan)(yan)箱(xiang)。從而達到溫(wen)(wen)(wen)(wen)(wen)度快速交變的目的。

冷熱沖擊試驗機維護(hu)保養(yang)

冷(leng)熱(re)沖擊試驗機保(bao)(bao)養(yang)(yang)(yang)機械要(yao)保(bao)(bao)證質(zhi)(zhi)(zhi)量(liang)(liang)， 按規定項(xiang)目和(he)要(yao)求逐項(xiang)進行，不得漏(lou)保(bao)(bao)或不保(bao)(bao)。保(bao)(bao)養(yang)(yang)(yang)項(xiang)目、保(bao)(bao)養(yang)(yang)(yang)質(zhi)(zhi)(zhi)量(liang)(liang)和(he)保(bao)(bao)養(yang)(yang)(yang)中發現的問題應作(zuo)好(hao)記錄(lu)，報本部門(men)專(zhuan)工;保(bao)(bao)養(yang)(yang)(yang)人員(yuan)和(he)保(bao)(bao)養(yang)(yang)(yang)部門(men)應做到 “三檢(jian)(jian)(jian)- -交(自(zi)檢(jian)(jian)(jian)、互檢(jian)(jian)(jian)、專(zhuan)職檢(jian)(jian)(jian)查和(he)一次交接合格)”，不斷總結(jie)保(bao)(bao)養(yang)(yang)(yang)經驗，提高保(bao)(bao)養(yang)(yang)(yang)質(zhi)(zhi)(zhi)量(liang)(liang)。在維(wei)護保(bao)(bao)養(yang)(yang)(yang)的前(qian)提下(xia)，冷(leng)熱(re)沖擊試驗機要(yao)如下(xia)執行與(yu)滿足(zu)標準。
