恒溫恒濕實(shi)驗箱常見故(gu)障及注(zhu)意事項:
1.為避免恒溫恒濕(shi)試(shi)驗箱發生(sheng)機(ji)器故障,請提供額定電(dian)壓范圍內的電(dian)源。
2.為了防止(zhi)觸電(dian)(dian)或(huo)產生誤動作和(he)故障,在安裝和(he)接線結束之前,請不要接通(tong)電(dian)(dian)源。
3.本產品(pin)為非防爆產品(pin),請(qing)不(bu)要在有可燃或爆炸性氣(qi)體的壞境中使用恒溫恒濕機。
4.儀器工作中請盡量不(bu)要打開(kai)試驗箱門(men),高溫時(shi)打開(kai)可(ke)能會對(dui)操(cao)作人(ren)員(yuan)造成燙(tang)傷,低溫時(shi)打開(kai)可(ke)能會對(dui)工作人(ren)員(yuan)早場凍傷,并且可(ke)能造成蒸發(fa)器結(jie)冰,影(ying)響制冷效果。若一(yi)定(ding)要打開(kai),請做好(hao)一(yi)定(ding)的防護(hu)工作,
5.禁止擅自拆卸、加工、改造或(huo)(huo)修理(li)恒(heng)溫恒(heng)濕機(ji),否則(ze)會有產生異常動作、觸(chu)電或(huo)(huo)火災的危險。
6.機體的通(tong)風(feng)孔(kong)需保持通(tong)暢,以免發生故障(zhang)、動(dong)作異(yi)常、壽命降低和火災(zai)。
7.開箱時若發現機器損壞或(huo)變形,請不要(yao)使(shi)用。
8.機(ji)器安裝設置時(shi)注意不要讓灰(hui)塵(chen)、線頭、鐵屑或其(qi)他東西進入,否則會發生(sheng)錯誤(wu)動作或故障(zhang)。
9.接(jie)線必須正確,一(yi)定(ding)要進(jin)行接(jie)地(di)。不(bu)接(jie)地(di)可能(neng)造成觸電、錯誤動作事故、顯示(shi)不(bu)正常或測量有較大誤差。
10.定期檢查端子(zi)螺絲(si)和固定架,請不(bu)要在松動的情況下使(shi)用。
11.儀表運(yun)轉期(qi)間,電源入力端子(zi)蓋(gai)必須安裝在端子(zi)板上(shang)以防觸電。
12.儀表在運轉中,進行修改(gai)設定、信號輸出、啟動、停止等操作之前,應充分地考慮安全性,錯誤的操作會使工作設備損壞或發生(sheng)故障。
13.請(qing)使用干(gan)布擦(ca)拭儀(yi)表,不要使用酒精、汽油(you)或其他有機溶劑,不要把水濺到儀(yi)表上,如果(guo)儀(yi)表浸入水中(zhong),請(qing)立即停(ting)止使用,否則有漏(lou)電(dian)(dian)、觸電(dian)(dian)或火災(zai)的危險。
14.儀(yi)表(biao)內部(bu)零件有一定的(de)壽命期(qi)限,為持續安全地(di)使用本(ben)儀(yi)表(biao),請定期(qi)進行保養(yang)和(he)維護。報廢本(ben)產品時,請依工業垃圾處理(li)。

你(ni)知道怎樣正確(que)維(wei)護和保(bao)養(yang)恒(heng)(heng)溫恒(heng)(heng)濕機?
恒溫(wen)恒濕(shi)試(shi)驗(yan)箱是集合了高溫(wen)、低(di)溫(wen)、濕(shi)熱(re)為一(yi)體的(de)試(shi)驗(yan)箱—高低(di)溫(wen)濕(shi)熱(re)交變試(shi)驗(yan)箱,它(ta)的(de)修理難度較(jiao)其(qi)它(ta)環境試(shi)驗(yan)設備大,且具有代(dai)表性。下面就高低(di)溫(wen)濕(shi)熱(re)交變試(shi)驗(yan)箱為例,談(tan)一(yi)談(tan)恒溫(wen)恒濕(shi)試(shi)驗(yan)箱的(de)構(gou)造(zao)及一(yi)些常見故障(zhang)和(he)排除方(fang)法。
一、恒(heng)溫恒(heng)濕(shi)試驗箱的(de)構造
恒溫恒濕(shi)(shi)(shi)(shi)試驗箱由箱體、風循(xun)環系(xi)統(tong)(tong)、制(zhi)(zhi)冷系(xi)統(tong)(tong)、加(jia)熱系(xi)統(tong)(tong)和(he)(he)控(kong)濕(shi)(shi)(shi)(shi)系(xi)統(tong)(tong)組(zu)成。風循(xun)環系(xi)統(tong)(tong)一般采用(yong)(yong)可(ke)調(diao)節送風方向的結(jie)構(gou);加(jia)濕(shi)(shi)(shi)(shi)系(xi)統(tong)(tong)有采用(yong)(yong)鍋爐(lu)加(jia)濕(shi)(shi)(shi)(shi)和(he)(he)表面蒸發二(er)種(zhong);降溫、除濕(shi)(shi)(shi)(shi)系(xi)統(tong)(tong)采用(yong)(yong)空調(diao)工況制(zhi)(zhi)冷結(jie)構(gou);加(jia)熱系(xi)統(tong)(tong)采用(yong)(yong)電熱鰭片(pian)加(jia)熱和(he)(he)電爐(lu)絲直(zhi)接加(jia)熱二(er)種(zhong)結(jie)構(gou);溫濕(shi)(shi)(shi)(shi)度(du)測(ce)(ce)試方法采用(yong)(yong)干(gan)濕(shi)(shi)(shi)(shi)球測(ce)(ce)試方法,也有用(yong)(yong)濕(shi)(shi)(shi)(shi)度(du)傳感(gan)器直(zhi)接測(ce)(ce)量方法;控(kong)制(zhi)(zhi)和(he)(he)顯示操作界面采用(yong)(yong)溫濕(shi)(shi)(shi)(shi)度(du)分開獨立和(he)(he)溫濕(shi)(shi)(shi)(shi)度(du)組(zu)合(he)控(kong)制(zhi)(zhi)器等方式。
二、恒溫恒濕試驗箱的一些常見故障和排(pai)除方法
◆在高溫(wen)試驗(yan)中,如(ru)溫(wen)度(du)(du)變化達(da)不到試驗(yan)溫(wen)度(du)(du)值時(shi),可(ke)以(yi)檢(jian)查(cha)(cha)電(dian)(dian)器系統(tong)(tong),逐一排(pai)除故(gu)(gu)障。如(ru)溫(wen)度(du)(du)升得很慢,就(jiu)要查(cha)(cha)看(kan)風(feng)(feng)循環(huan)(huan)系統(tong)(tong),看(kan)一下(xia)風(feng)(feng)循環(huan)(huan)的調節(jie)擋板是否開啟正常(chang),反之,就(jiu)檢(jian)查(cha)(cha)風(feng)(feng)循環(huan)(huan)的電(dian)(dian)機運轉(zhuan)是否正常(chang)。如(ru)溫(wen)度(du)(du)過沖(chong)厲害那么就(jiu)需要整定PID的設置參(can)數。如(ru)果溫(wen)度(du)(du)直(zhi)接上(shang)升,過溫(wen)保護(hu),那么,控制器出故(gu)(gu)障,須(xu)更換控制儀表。
◆低(di)溫(wen)(wen)達不(bu)(bu)到試驗(yan)的(de)指標,那你就(jiu)要觀察溫(wen)(wen)度(du)(du)(du)的(de)變(bian)化,是(shi)溫(wen)(wen)度(du)(du)(du)降的(de)很(hen)慢,還是(shi)溫(wen)(wen)度(du)(du)(du)到一(yi)定值后(hou)溫(wen)(wen)度(du)(du)(du)有回升的(de)趨勢,前者(zhe)就(jiu)要檢查一(yi)下,做低(di)溫(wen)(wen)試驗(yan)前是(shi)否(fou)將工(gong)(gong)作室烘(hong)干,使(shi)工(gong)(gong)作室保持干燥后(hou)再將試驗(yan)樣(yang)品(pin)放入工(gong)(gong)作室內再做試驗(yan),工(gong)(gong)作室內的(de)試驗(yan)樣(yang)品(pin)是(shi)否(fou)放置的(de)過多,使(shi)工(gong)(gong)作室內的(de)風不(bu)(bu)能(neng)充分(fen)循環(huan),在(zai)(zai)排除上述(shu)原(yuan)因后(hou),就(jiu)要考慮是(shi)否(fou)是(shi)制(zhi)冷系統中(zhong)的(de)故障了,轉子(zi)泵(beng)這(zhe)樣(yang)就(jiu)要請廠家的(de)專業人員進行檢修。后(hou)者(zhe)的(de)現象是(shi)設(she)備(bei)的(de)使(shi)用環(huan)境(jing)不(bu)(bu)好(hao)所致,設(she)備(bei)放置的(de)環(huan)境(jing)溫(wen)(wen)度(du)(du)(du),放置的(de)位置(箱體后(hou)與墻的(de)距離)要滿足要求(qiu)(在(zai)(zai)設(she)備(bei)操作使(shi)用說(shuo)明中(zhong)都有規定)。
◆在做濕(shi)(shi)(shi)(shi)熱試驗(yan)中(zhong),出現(xian)實際濕(shi)(shi)(shi)(shi)度(du)會達到100%或(huo)(huo)者(zhe)實際濕(shi)(shi)(shi)(shi)度(du)與目標濕(shi)(shi)(shi)(shi)度(du)相差很大,數(shu)值(zhi)低得很多,前(qian)者(zhe)的(de)(de)現(xian)象(xiang):可(ke)(ke)能(neng)是(shi)(shi)(shi)濕(shi)(shi)(shi)(shi)球傳(chuan)感器(qi)上的(de)(de)紗布干燥(zao)引起,那就(jiu)(jiu)要(yao)(yao)檢(jian)查(cha)濕(shi)(shi)(shi)(shi)球傳(chuan)感器(qi)的(de)(de)水(shui)(shui)(shui)(shui)槽中(zhong)是(shi)(shi)(shi)否(fou)(fou)缺水(shui)(shui)(shui)(shui),水(shui)(shui)(shui)(shui)槽中(zhong)的(de)(de)水(shui)(shui)(shui)(shui)位(wei)(wei)是(shi)(shi)(shi)由一水(shui)(shui)(shui)(shui)位(wei)(wei)控(kong)(kong)制(zhi)器(qi)自動(dong)控(kong)(kong)制(zhi)的(de)(de),查(cha)水(shui)(shui)(shui)(shui)位(wei)(wei)控(kong)(kong)制(zhi)器(qi)供(gong)水(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)是(shi)(shi)(shi)否(fou)(fou)供(gong)水(shui)(shui)(shui)(shui)正常(chang)(chang),水(shui)(shui)(shui)(shui)位(wei)(wei)控(kong)(kong)制(zhi)器(qi)工(gong)作是(shi)(shi)(shi)否(fou)(fou)正常(chang)(chang)。另一種可(ke)(ke)能(neng)就(jiu)(jiu)是(shi)(shi)(shi)濕(shi)(shi)(shi)(shi)球紗布因使(shi)用時間(jian)長,或(huo)(huo)供(gong)水(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)質純凈(jing)度(du)的(de)(de)原(yuan)因,會使(shi)紗布變硬,使(shi)紗布無法吸(xi)收(shou)水(shui)(shui)(shui)(shui)份而(er)干燥(zao),只要(yao)(yao)更換或(huo)(huo)清洗紗布即可(ke)(ke)排(pai)除以(yi)上現(xian)象(xiang)。后者(zhe)的(de)(de)現(xian)象(xiang)主要(yao)(yao)是(shi)(shi)(shi)加濕(shi)(shi)(shi)(shi)系(xi)(xi)統(tong)不工(gong)作,查(cha)看加濕(shi)(shi)(shi)(shi)系(xi)(xi)統(tong)的(de)(de)供(gong)水(shui)(shui)(shui)(shui)系(xi)(xi)統(tong),供(gong)水(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)內(nei)是(shi)(shi)(shi)否(fou)(fou)有(you)一定的(de)(de)水(shui)(shui)(shui)(shui)量,控(kong)(kong)制(zhi)加濕(shi)(shi)(shi)(shi)鍋爐水(shui)(shui)(shui)(shui)位(wei)(wei)的(de)(de)水(shui)(shui)(shui)(shui)位(wei)(wei)控(kong)(kong)制(zhi)是(shi)(shi)(shi)否(fou)(fou)正常(chang)(chang),加濕(shi)(shi)(shi)(shi)鍋爐內(nei)的(de)(de)水(shui)(shui)(shui)(shui)位(wei)(wei)是(shi)(shi)(shi)否(fou)(fou)正常(chang)(chang)。如以(yi)上一切(qie)都(dou)正常(chang)(chang),那就(jiu)(jiu)要(yao)(yao)檢(jian)查(cha)電器(qi)控(kong)(kong)制(zhi)系(xi)(xi)統(tong),這要(yao)(yao)請專業(ye)維修人員進行檢(jian)修。
◆設備在試(shi)驗(yan)運行(xing)過程中突(tu)然(ran)出現(xian)故障(zhang)時,控(kong)制(zhi)儀表上出現(xian)對應(ying)的(de)(de)故障(zhang)顯示(shi)提示(shi)并有(you)聲(sheng)訊報(bao)警(jing)提示(shi)。操(cao)作(zuo)人員(yuan)可以對照設備的(de)(de)操(cao)作(zuo)使用中的(de)(de)故障(zhang)排(pai)除(chu)一章中快速檢查出屬(shu)于哪一類故障(zhang),即可請(qing)專業人員(yuan)快速排(pai)除(chu)故障(zhang),以確保試(shi)驗(yan)的(de)(de)正(zheng)常進行(xing)。其(qi)它(ta)環境試(shi)驗(yan)設備在使用中還會(hui)有(you)其(qi)它(ta)的(de)(de)現(xian)象,那就要具體現(xian)象,具體分析和排(pai)除(chu)。
恒(heng)溫恒(heng)濕(shi)試驗箱還要定期(qi)(qi)進行維(wei)護保養,制冷系(xi)統(tong)的冷凝器(qi)定期(qi)(qi)清(qing)理,對于活動部(bu)件應(ying)按(an)說明書加油潤滑(hua),電器(qi)控制系(xi)統(tong)定期(qi)(qi)維(wei)護檢查等等,這(zhe)些工(gong)作(zuo)是必不可少的
