[恒溫恒濕箱]恒溫恒濕箱的一些小故障處理方法
[恒溫恒濕箱]恒(heng)溫(wen)恒(heng)濕箱的一(yi)些小(xiao)故障(zhang)處理方法
恒(heng)(heng)(heng)(heng)溫(wen)(wen)恒(heng)(heng)(heng)(heng)濕(shi)(shi)箱是(shi)用于(yu)檢(jian)測材料(liao)(如電子(zi)、電器、通訊、儀表、車(che)輛、塑膠制(zhi)品、金屬、食品、化學(xue)、建材、醫療、航天等制(zhi)品)在各(ge)種環境下性能的(de)設備(bei)及試驗(yan)各(ge)種材料(liao)耐(nai)熱、耐(nai)寒、耐(nai)干、耐(nai)濕(shi)(shi)性能。但是(shi)我(wo)們(men)在日常使(shi)(shi)用它的(de)時(shi)(shi)候會由于(yu)使(shi)(shi)用年(nian)限(xian)的(de)限(xian)制(zhi)會出現各(ge)種各(ge)樣的(de)小(xiao)(xiao)故障(zhang),這(zhe)個時(shi)(shi)候我(wo)們(men)就(jiu)需要(yao)對(dui)它進行維修。如果(guo)因為這(zhe)些(xie)小(xiao)(xiao)故障(zhang)去購買(mai)新的(de)恒(heng)(heng)(heng)(heng)溫(wen)(wen)恒(heng)(heng)(heng)(heng)濕(shi)(shi)箱,那么這(zhe)不僅(jin)僅(jin)浪費了材料(liao)檢(jian)測的(de)時(shi)(shi)間還增加了經(jing)濟的(de)投入。因此我(wo)們(men)需要(yao)對(dui)它的(de)故障(zhang)有所(suo)了解,出現故障(zhang)才能及時(shi)(shi)解決。下面分享恒(heng)(heng)(heng)(heng)溫(wen)(wen)恒(heng)(heng)(heng)(heng)濕(shi)(shi)箱的(de)一(yi)些(xie)小(xiao)(xiao)故障(zhang)處(chu)理方法:
故障一(yi):濕(shi)球紗(sha)布過于干燥
在使(shi)用恒(heng)溫(wen)恒(heng)濕(shi)箱做(zuo)濕(shi)度試驗的(de)時候,出現了實際濕(shi)度達到100%,發生這個故障的(de)原(yuan)因(yin)可能是(shi)濕(shi)球(qiu)傳(chuan)(chuan)感(gan)器(qi)(qi)上的(de)濕(shi)球(qiu)紗布(bu)干燥引起(qi),我(wo)們需要檢查濕(shi)球(qiu)傳(chuan)(chuan)感(gan)器(qi)(qi)的(de)水(shui)槽是(shi)否(fou)缺(que)水(shui),如不缺(que)水(shui)請檢查濕(shi)球(qiu)紗布(bu)的(de)懸掛方式及懸掛位(wei)置。正常情況下,必須將紗布(bu)掛在下面的(de)一支傳(chuan)(chuan)感(gan)器(qi)(qi)上,且紗布(bu)下端必須可靠的(de)浸在積(ji)水(shui)頭水(shui)槽內,以便濕(shi)球(qiu)紗布(bu)能可靠的(de)吸水(shui)。
故障二:電氣系統故障
當出(chu)現此類(lei)故(gu)障時,應該首先檢(jian)查(cha)兩組制冷系(xi)統低溫(wen)級壓(ya)(ya)縮機(ji)(ji)的(de)排氣和吸(xi)氣壓(ya)(ya)力都比正常值偏低;二七吸(xi)氣壓(ya)(ya)力呈抽空(kong)狀態;出(chu)現此類(lei)情況說明制冷機(ji)(ji)組的(de)制冷劑輛不足(zu)所致(zhi);因(yin)此出(chu)現此類(lei)故(gu)障只需要維修壓(ya)(ya)縮機(ji)(ji)即可。
故障(zhang)三:制冷系統(tong)出現故障(zhang)
當制(zhi)冷(leng)系(xi)(xi)統(tong)(tong)出(chu)現了問題的(de)時候(hou)我們應該先對(dui)制(zhi)冷(leng)系(xi)(xi)統(tong)(tong)進行查(cha)漏(lou),用檢漏(lou)儀(yi)來檢查(cha)漏(lou)點在(zai)哪,如果發現是熱氣旁(pang)通電(dian)磁閥(fa)(fa)的(de)閥(fa)(fa)桿裂了有(you)細縫,則更換此電(dian)磁閥(fa)(fa),如發現其(qi)它(ta)地方的(de)泄漏(lou),則用氧焊(han)將泄漏(lou)處補焊(han)完整,再對(dui)系(xi)(xi)統(tong)(tong)重新充氟,系(xi)(xi)統(tong)(tong)運行即(ji)可(ke)恢(hui)復正常。
