  二(er)手冷藏集裝箱(xiang)在制冷的過程中(zhong)經常(chang)會出現一些故(gu)障,導致這些故(gu)障原因很多(duo)。最(zui)常(chang)見(jian)幾(ji)種故(gu)障及判定(ding)方(fang)法(fa)如下:

  打(da)開(kai)電(dian)源(yuan)的開(kai)關(guan),如果是(shi)制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)系(xi)統(tong)(tong)不工(gong)(gong)(gong)作(zuo),首先應(ying)該檢查電(dian)源(yuan)轉換開(kai)關(guan)是(shi)否(fou)在你選(xuan)擇(ze)的電(dian)壓上,電(dian)源(yuan)插座是(shi)否(fou)是(shi)插好(hao),保險絲(si)是(shi)否(fou)是(shi)損壞(huai);打(da)開(kai)電(dian)源(yuan)的開(kai)關(guan),制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)機各(ge)系(xi)統(tong)(tong)都是(shi)在工(gong)(gong)(gong)作(zuo),但(dan)不制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)。這種(zhong)情(qing)況下一般(ban)沒有制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)了(le)(le);開(kai)機后(hou),制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)機工(gong)(gong)(gong)作(zuo)幾分(fen)鐘就能自動停機,幾分(fen)鐘之(zhi)后(hou)又自動的開(kai)機,這種(zhong)情(qing)況下多是(shi)缺少著制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)。如果開(kai)機之(zhi)后(hou)20分(fen)鐘以(yi)后(hou),通(tong)過制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)顯示(shi)鏡可(ke)見氣(qi)泡,即屬于缺少制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)。如果,夏天出現(xian)自動停機情(qing)況,若(ruo)不是(shi)缺少制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑(ji),那(nei)么就是(shi)冷(leng)(leng)(leng)凝器(qi)灰塵太(tai)多,或者是(shi)由于制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)過多造成的;制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)機正(zheng)在工(gong)(gong)(gong)作(zuo),電(dian)腦不能儲存(cun)實(shi)際(ji)溫(wen)度,一般(ban)是(shi)制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)機的溫(wen)度感應(ying)器(qi)或電(dian)腦系(xi)統(tong)(tong)壞(huai)了(le)(le);二手(shou)冷(leng)(leng)(leng)藏(zang)集(ji)裝(zhuang)箱(xiang)各(ge)系(xi)統(tong)(tong)工(gong)(gong)(gong)作(zuo)正(zheng)常,制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)狀(zhuang)況也正(zheng)常,但(dan)是(shi),反映在溫(wen)度記錄紙表盤上的溫(wen)度波動范圍太(tai)大。原因可(ke)能是(shi):通(tong)氣(qi)口(kou)沒關(guan)閉、冷(leng)(leng)(leng)藏(zang)集(ji)裝(zhuang)箱(xiang)門沒有關(guan)嚴、或者是(shi)冷(leng)(leng)(leng)藏(zang)集(ji)裝(zhuang)箱(xiang)局部破損,導致箱(xiang)內冷(leng)(leng)(leng)氣(qi)泄漏;

  一(yi)般來(lai)說(shuo),二手(shou)(shou)冷(leng)(leng)(leng)(leng)藏集(ji)裝(zhuang)(zhuang)箱(xiang)(xiang)(xiang)的(de)(de)融霜(shuang)周期是(shi)在(zai)(zai)制(zhi)(zhi)冷(leng)(leng)(leng)(leng)前(qian)設(she)定(ding)的(de)(de),在(zai)(zai)制(zhi)(zhi)冷(leng)(leng)(leng)(leng)過(guo)程(cheng)中融霜(shuang)的(de)(de)規律性很強。如(ru)(ru)(ru)(ru)果在(zai)(zai)執行(xing)融霜(shuang)的(de)(de)時候出現持續融霜(shuang)時間過(guo)長,則(ze)表(biao)(biao)明(ming)(ming)融霜(shuang)控制(zhi)(zhi)開關(guan)壞(huai)了。如(ru)(ru)(ru)(ru)果融霜(shuang)在(zai)(zai)制(zhi)(zhi)冷(leng)(leng)(leng)(leng)機(ji)工(gong)(gong)作(zuo)期間終止,則(ze)表(biao)(biao)明(ming)(ming)加熱器(qi)(qi)壞(huai)了;冷(leng)(leng)(leng)(leng)藏集(ji)裝(zhuang)(zhuang)箱(xiang)(xiang)(xiang)正(zheng)運(yun)行(xing)的(de)(de)時候,如(ru)(ru)(ru)(ru)果發現設(she)定(ding)的(de)(de)溫(wen)度(du)與(yu)人工(gong)(gong)在(zai)(zai)箱(xiang)(xiang)(xiang)內實測溫(wen)度(du)相同,而二手(shou)(shou)冷(leng)(leng)(leng)(leng)藏集(ji)裝(zhuang)(zhuang)箱(xiang)(xiang)(xiang)溫(wen)度(du)記錄表(biao)(biao)盤(pan)顯示的(de)(de)溫(wen)度(du)與(yu)前(qian)者相差(cha)過(guo)大(da),這表(biao)(biao)明(ming)(ming)溫(wen)度(du)感(gan)溫(wen)探頭壞(huai)了。二手(shou)(shou)冷(leng)(leng)(leng)(leng)藏集(ji)裝(zhuang)(zhuang)箱(xiang)(xiang)(xiang)故(gu)(gu)障的(de)(de)診(zhen)(zhen)斷(duan)方法(fa)硬(ying)(ying)故(gu)(gu)障和軟故(gu)(gu)障是(shi)不(bu)同的(de)(de),那上(shang)海順號集(ji)裝(zhuang)(zhuang)箱(xiang)(xiang)(xiang)服務(wu)有(you)限(xian)公司(si)對(dui)于這兩種不(bu)同的(de)(de)診(zhen)(zhen)斷(duan)方法(fa)來(lai)具體說(shuo)明(ming)(ming)一(yi)下。對(dui)于硬(ying)(ying)故(gu)(gu)障:故(gu)(gu)障現象已(yi)明(ming)(ming)顯反(fan)映(ying),可根據(ju)系(xi)(xi)統運(yun)行(xing)狀(zhuang)況(kuang)和相關(guan)元件的(de)(de)動作(zuo)情況(kuang)去(qu)查找。比如(ru)(ru)(ru)(ru)制(zhi)(zhi)冷(leng)(leng)(leng)(leng)系(xi)(xi)統中壓(ya)(ya)(ya)(ya)縮(suo)機(ji)不(bu)能(neng)(neng)啟動,可從控制(zhi)(zhi)壓(ya)(ya)(ya)(ya)縮(suo)機(ji)運(yun)行(xing)的(de)(de)相關(guan)電(dian)路(lu)去(qu)排查,查看主(zhu)電(dian)路(lu)是(shi)否(fou)有(you)電(dian)、主(zhu)接(jie)觸(chu)器(qi)(qi)是(shi)否(fou)完好(hao)、控制(zhi)(zhi)電(dian)路(lu)是(shi)否(fou)有(you)電(dian)、壓(ya)(ya)(ya)(ya)縮(suo)機(ji)高(gao)低壓(ya)(ya)(ya)(ya)保護開關(guan)是(shi)否(fou)正(zheng)常,高(gao)壓(ya)(ya)(ya)(ya)開關(guan)動作(zuo)后是(shi)否(fou)手(shou)(shou)動復位(wei)、控制(zhi)(zhi)板(ban)副繼電(dian)器(qi)(qi)是(shi)否(fou)正(zheng)常、電(dian)腦控制(zhi)(zhi)板(ban)是(shi)否(fou)存在(zai)(zai)故(gu)(gu)障等。對(dui)于軟故(gu)(gu)障:需要(yao)根據(ju)制(zhi)(zhi)冷(leng)(leng)(leng)(leng)系(xi)(xi)統所反(fan)映(ying)出的(de)(de)全部(bu)現象,綜(zong)合(he)分析診(zhen)(zhen)斷(duan)。然而,根據(ju)溫(wen)度(du)圖表(biao)(biao)曲線走勢(shi),僅能(neng)(neng)初(chu)略地(di)反(fan)映(ying)出系(xi)(xi)統工(gong)(gong)作(zuo)的(de)(de)好(hao)壞(huai)。二手(shou)(shou)冷(leng)(leng)(leng)(leng)藏集(ji)裝(zhuang)(zhuang)箱(xiang)(xiang)(xiang)的(de)(de)維度(du)在(zai)(zai)漸漸回升,表(biao)(biao)明(ming)(ming)系(xi)(xi)統制(zhi)(zhi)冷(leng)(leng)(leng)(leng)能(neng)(neng)力(li)明(ming)(ming)顯不(bu)足。導致這一(yi)現象,卻可能(neng)(neng)有(you)多方面的(de)(de)原因(yin),要(yao)進(jin)一(yi)步(bu)觀察它現象。例(li)如(ru)(ru)(ru)(ru)壓(ya)(ya)(ya)(ya)縮(suo)機(ji)吸、排氣口的(de)(de)壓(ya)(ya)(ya)(ya)力(li)等,才能(neng)(neng)正(zheng)確診(zhen)(zhen)斷(duan)。發現壓(ya)(ya)(ya)(ya)縮(suo)機(ji)吸人壓(ya)(ya)(ya)(ya)力(li)很低,則(ze)故(gu)(gu)障可能(neng)(neng)是(shi):系(xi)(xi)統制(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑(ji)不(bu)足;冰塞(sai);膨(peng)脹(zhang)閥卡死;或干(gan)燥器(qi)(qi)臟堵等。

  系(xi)統冷(leng)劑(ji)(ji)量不足,診斷方(fang)法是,暫時全(quan)關儲液(ye)(ye)罐出(chu)口閥,將二手(shou)冷(leng)藏(zang)集(ji)裝(zhuang)箱(xiang)(xiang)運(yun)行在冷(leng)凍模式,觀(guan)察儲液(ye)(ye)罐中(zhong)的(de)(de)(de)制(zhi)冷(leng)劑(ji)(ji)是否能回(hui)收至正常的(de)(de)(de)液(ye)(ye)位。冰塞,可將儲液(ye)(ye)罐出(chu)口閥全(quan)關并(bing)在冷(leng)凍模式下(xia)運(yun)行壓縮機,使系(xi)統管(guan)路處于(yu)真空狀態,即可融化管(guan)路中(zhong)的(de)(de)(de)冰,多(duo)次反復(fu)操(cao)作后,再更換(huan)(huan)干燥劑(ji)(ji),即可解決問題。膨脹(zhang)閥卡死(si),徹底解決的(de)(de)(de)方(fang)法,是更換(huan)(huan)膨脹(zhang)閥,但(dan)故障二手(shou)冷(leng)藏(zang)集(ji)裝(zhuang)箱(xiang)(xiang)的(de)(de)(de)放置(zhi)位置(zhi)必須便于(yu)現場(chang)施工(gong)。以(yi)上內容有(you)(you)集(ji)裝(zhuang)箱(xiang)(xiang)服務有(you)(you)限公司(si)整理發布。
