冷熱沖擊試驗箱各部件的清洗要點

冷(leng)(leng)(leng)(leng)(leng)熱沖擊試驗箱應固定(ding)每3個(ge)月清(qing)洗一次冷(leng)(leng)(leng)(leng)(leng)凝器，對(dui)(dui)于冷(leng)(leng)(leng)(leng)(leng)凍系(xi)統采(cai)用風冷(leng)(leng)(leng)(leng)(leng)冷(leng)(leng)(leng)(leng)(leng)卻(que)的(de)，應定(ding)時檢修冷(leng)(leng)(leng)(leng)(leng)凝風機，并對(dui)(dui)冷(leng)(leng)(leng)(leng)(leng)凝器進(jin)行(xing)去污除(chu)塵(chen)，以(yi)保(bao)證(zheng)其(qi)(qi)良好(hao)的(de)通風換熱性能(neng);對(dui)(dui)于冷(leng)(leng)(leng)(leng)(leng)凍系(xi)統采(cai)用水冷(leng)(leng)(leng)(leng)(leng)冷(leng)(leng)(leng)(leng)(leng)卻(que)的(de)，除(chu)了要保(bao)證(zheng)其(qi)(qi)進(jin)水壓力、進(jin)水溫度在(zai)規定(ding)范圍(wei)內(nei)，還必(bi)須保(bao)證(zheng)相(xiang)應流量，并定(ding)時對(dui)(dui)冷(leng)(leng)(leng)(leng)(leng)凝器內(nei)部(bu)進(jin)行(xing)清(qing)洗除(chu)垢，以(yi)獲取其(qi)(qi)持續的(de)換熱性能(neng)。

冷熱(re)沖(chong)擊試驗箱如是長(chang)時(shi)間做低溫(wen)時(shi)，當(dang)做完一個周期后(hou)，應設定(ding)(ding)(ding)溫(wen)度為110度，小(xiao)幅度開箱門做兩個小(xiao)時(shi)除霜處理。同時(shi)應堅(jian)持每次(ci)試驗完畢后(hou)，將溫(wen)度設定(ding)(ding)(ding)在環境溫(wen)度附近，工作30分(fen)鐘左右，再切斷電源(yuan)，并擦干(gan)凈工作室內(nei)壁。冷熱(re)沖(chong)擊試驗箱長(chang)期停機不(bu)使用，應定(ding)(ding)(ding)時(shi)每半(ban)月通電，通電時(shi)間不(bu)小(xiao)于1小(xiao)時(shi)，并檢測設備相關零(ling)部件(jian)運行是否正(zheng)常。

冷熱沖(chong)(chong)擊試驗箱(xiang)(xiang)應(ying)定(ding)(ding)時清(qing)洗(xi)蒸發(fa)器(qi)(qi)(qi)(qi)(qi)，因試品(pin)的(de)潔凈(jing)等(deng)級各異(yi)，在強制風(feng)(feng)循環(huan)作(zuo)用下(xia)，蒸發(fa)器(qi)(qi)(qi)(qi)(qi)上會(hui)凝聚(ju)很多塵埃等(deng)小顆粒物(wu)體(ti)，應(ying)定(ding)(ding)時進行清(qing)洗(xi)。低溫試驗箱(xiang)(xiang)循環(huan)風(feng)(feng)葉、冷凝器(qi)(qi)(qi)(qi)(qi)風(feng)(feng)機清(qing)潔和校平衡：與清(qing)洗(xi)蒸發(fa)器(qi)(qi)(qi)(qi)(qi)相(xiang)似，因試驗箱(xiang)(xiang)的(de)工作(zuo)環(huan)境各異(yi)，循環(huan)風(feng)(feng)葉、冷凝器(qi)(qi)(qi)(qi)(qi)風(feng)(feng)機上會(hui)凝聚(ju)很多塵埃等(deng)小顆粒物(wu)體(ti)，應(ying)定(ding)(ding)時進行清(qing)洗(xi)。冷熱沖(chong)(chong)擊試驗箱(xiang)(xiang)的(de)水路(lu)、加(jia)濕器(qi)(qi)(qi)(qi)(qi)清(qing)洗(xi)，若水路(lu)不(bu)暢、加(jia)濕器(qi)(qi)(qi)(qi)(qi)結(jie)垢易(yi)導致加(jia)濕器(qi)(qi)(qi)(qi)(qi)干燒(shao)，可能損壞加(jia)濕器(qi)(qi)(qi)(qi)(qi)，所以(yi)必須定(ding)(ding)時對水路(lu)、加(jia)濕器(qi)(qi)(qi)(qi)(qi)進行清(qing)洗(xi)。
