溫度沖擊(ji)試(shi)驗箱 （冷(leng)熱沖擊試驗箱(xiang)）適用于(yu)電子、汽(qi)車(che)配件、塑膠等行(xing)業，測(ce)試各種材料對(dui)高、低溫(wen)的反復沖擊能力。檢測(ce)產品(pin)于(yu)熱脹冷縮(suo)所(suo)產生的化(hua)學變化(hua)或物(wu)理傷害，確保(bao)產品(pin)的品(pin)質。

沖擊溫度：+150～-60℃;

電源：380V±10﹪ 50Hz

溫(wen)度(du)沖擊試驗箱在高(gao)溫(wen)試驗中，如溫(wen)度(du)變化達不到試驗溫(wen)度(du)值時(shi)，可以檢查電器系(xi)統，逐一排除故障。如溫(wen)度(du)升得很慢，就要查看(kan)風(feng)循(xun)(xun)環系(xi)統，看(kan)一下風(feng)循(xun)(xun)環的(de)調節擋板是否(fou)開啟正常。  

低溫(wen)達(da)不到試(shi)驗(yan)(yan)的(de)(de)(de)(de)指(zhi)標觀察溫(wen)度(du)(du)的(de)(de)(de)(de)變化，是(shi)(shi)(shi)(shi)(shi)溫(wen)度(du)(du)降的(de)(de)(de)(de)很慢(man)，還是(shi)(shi)(shi)(shi)(shi)溫(wen)度(du)(du)到一定值(zhi)后溫(wen)度(du)(du)有(you)回(hui)升的(de)(de)(de)(de)趨勢，前者就要檢(jian)查一下，做低溫(wen)試(shi)驗(yan)(yan)前是(shi)(shi)(shi)(shi)(shi)否(fou)將工(gong)作(zuo)(zuo)(zuo)室(shi)烘干(gan)，使(shi)工(gong)作(zuo)(zuo)(zuo)室(shi)保持干(gan)燥后再將試(shi)驗(yan)(yan)樣品放入(ru)工(gong)作(zuo)(zuo)(zuo)室(shi)內再做試(shi)驗(yan)(yan)，工(gong)作(zuo)(zuo)(zuo)室(shi)內的(de)(de)(de)(de)試(shi)驗(yan)(yan)樣品是(shi)(shi)(shi)(shi)(shi)否(fou)放置的(de)(de)(de)(de)過多(duo)，使(shi)工(gong)作(zuo)(zuo)(zuo)室(shi)內的(de)(de)(de)(de)風不能(neng)充分循(xun)環。如果不是(shi)(shi)(shi)(shi)(shi)類似(si)情況(kuang)，可以(yi)請專(zhuan)業的(de)(de)(de)(de)廠家(jia)（杰瑞(rui)）維修。做濕(shi)(shi)熱(re)試(shi)驗(yan)(yan)中(zhong)，出現實(shi)際(ji)濕(shi)(shi)度(du)(du)會(hui)達(da)到10或者實(shi)際(ji)濕(shi)(shi)度(du)(du)與0％目標濕(shi)(shi)度(du)(du)相(xiang)差很大，數值(zhi)低得很多(duo)。可能(neng)是(shi)(shi)(shi)(shi)(shi)濕(shi)(shi)球傳感器上(shang)的(de)(de)(de)(de)紗(sha)布干(gan)燥引起，那就要檢(jian)查濕(shi)(shi)球傳感器的(de)(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)槽中(zhong)是(shi)(shi)(shi)(shi)(shi)否(fou)缺水(shui)(shui)(shui)(shui)(shui)，水(shui)(shui)(shui)(shui)(shui)槽中(zhong)的(de)(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)位(wei)是(shi)(shi)(shi)(shi)(shi)由一水(shui)(shui)(shui)(shui)(shui)位(wei)控(kong)(kong)制(zhi)器自動(dong)控(kong)(kong)制(zhi)的(de)(de)(de)(de)。查水(shui)(shui)(shui)(shui)(shui)位(wei)控(kong)(kong)制(zhi)器供水(shui)(shui)(shui)(shui)(shui)系(xi)統(tong)是(shi)(shi)(shi)(shi)(shi)否(fou)供水(shui)(shui)(shui)(shui)(shui)正常(chang)，水(shui)(shui)(shui)(shui)(shui)位(wei)控(kong)(kong)制(zhi)器工(gong)作(zuo)(zuo)(zuo)是(shi)(shi)(shi)(shi)(shi)否(fou)正常(chang)。可以(yi)換個濕(shi)(shi)球紗(sha)布或用純凈水(shui)(shui)(shui)(shui)(shui)再試(shi)一下。或者請專(zhuan)業的(de)(de)(de)(de)電工(gong)檢(jian)修一下電路控(kong)(kong)制(zhi)系(xi)統(tong)這(zhe)塊。試(shi)驗(yan)(yan)人員除(chu)正確按操作(zuo)(zuo)(zuo)規程操作(zuo)(zuo)(zuo)，還應該對其(qi)結構有(you)所了解。冷熱(re)沖擊試(shi)驗(yan)(yan)機由箱體、風循(xun)環系(xi)統(tong)、制(zhi)冷系(xi)統(tong)、加(jia)溫(wen)系(xi)統(tong)和控(kong)(kong)濕(shi)(shi)系(xi)統(tong)組(zu)成。  

運作中打開尾門會對溫度沖擊試驗箱造成以下影響：  

1.高(gao)溫體內濕氣(qi)沖(chong)破箱對身體導致(zhi)損(sun)害(hai)；尾門里側仍(reng)然(ran)保持高(gao)溫對操作(zuo)過程工作(zuo)員造成危害(hai)；高(gao)溫汽體可能打開安全事故警報而造成錯誤；  

2.實驗整(zheng)個過程中電(dian)源總開關罩殼對制冷機組(zu)存在(zai)一定的損壞(huai)；除非是是試驗要求，否則不建議消費(fei)者在(zai)運行整(zheng)個過程中常常配電(dian)柜(ju)門。  

3.運(yun)用該高低溫箱時一定要保(bao)證是安全系(xi)數確實的接地系(xi)統，并保(bao)證電(dian)線接頭與零線電(dian)纜護套，防(fang)止導致靜電(dian)感應或(huo)損壞機械設備；  

4.干(gan)球溫度(du)紗布的安裝(zhuang)位置一(yi)(yi)定要精準，一(yi)(yi)般都是(shi)掛(gua)在儲水頭(tou)上(shang)方近一(yi)(yi)條溫度(du)感應器(qi)器(qi)上(shang)，才機械(xie)能取適當的空氣(qi)相對濕度(du)；  

5.漏(lou)電(dian)保(bao)(bao)護(hu)開(kai)關和超(chao)溫保(bao)(bao)護(hu)設備這類提供檢(jian)驗品以及工作(zuo)者人(ren)身(shen)安全的維(wei)護(hu)保(bao)(bao)養機械設備，一定要準時進行詳細的檢(jian)查；  

6.冷熱沖(chong)擊試(shi)驗箱(xiang)在(zai)運作中(zhong)，切忌(ji)以(yi)手觸檢(jian)查(cha)，防止安全事故或被風扇所傷從而造成風險性；  

7.非該設(she)備(bei)工(gong)作中(zhong)員不可以對恒溫恒濕(shi)設(she)備(bei)機器設(she)備(bei)恒溫箱機器設(she)備(bei)進行維(wei)修(xiu)和檢查(cha).并且在檢查(cha)時,除(chu)了(le)有(you)工(gong)作員進行之外,此外還(huan)要有(you)專業(ye)的(de)焊工(gong)及電路(lu)檢修(xiu)工(gong)作員,防止(zhi)不清楚的(de)工(gong)作員進行插線(xian)自動重合閘,從而(er)造(zao)成安全(quan)事故(gu)風(feng)險(xian)性。
