[恒溫恒濕試驗箱]什么樣的恒溫恒濕試驗箱性能好
[恒溫恒濕試驗箱]什(shen)么樣(yang)的(de)恒溫恒濕(shi)試(shi)驗箱性(xing)能好
客(ke)戶(hu)在(zai)選購(gou)恒溫恒濕(shi)試(shi)驗(yan)箱(xiang)(xiang)的時候就怕買到質量差、性能(neng)不好的恒溫恒濕(shi)試(shi)驗(yan)箱(xiang)(xiang)。那么(me)(me)恒溫恒濕(shi)試(shi)驗(yan)箱(xiang)(xiang)具備什么(me)(me)樣的條件才算是質量既好性能(neng)又(you)高呢?下面就幫大家來解決這樣的難題,不過在(zai)回(hui)答這個問題之前我們先來了解一下什么(me)(me)是恒溫恒濕(shi)試(shi)驗(yan)箱(xiang)(xiang),它的作用有哪些?
恒(heng)溫恒(heng)濕試(shi)(shi)(shi)(shi)驗(yan)箱是(shi)用(yong)于檢(jian)測材料在各種(zhong)環境下(xia)性能(neng)的儀器,它(ta)(ta)(ta)可(ke)以(yi)對(dui)各種(zhong)材料耐(nai)熱(re)、耐(nai)寒(han)、耐(nai)干、耐(nai)濕性能(neng)。適(shi)合電子(zi)、電器、通訊、儀表(biao)、車輛、塑(su)膠制(zhi)品(pin)、金屬、食品(pin)、化學、建材、醫(yi)療(liao)、航天等制(zhi)品(pin)做(zuo)試(shi)(shi)(shi)(shi)驗(yan)用(yong)來檢(jian)測它(ta)(ta)(ta)們的質量(liang)是(shi)否達標。目前國內的恒(heng)溫恒(heng)濕試(shi)(shi)(shi)(shi)驗(yan)箱種(zhong)類分為“臺(tai)(tai)式(shi)”和(he)“立(li)式(shi)”兩(liang)種(zhong),它(ta)(ta)(ta)們之間的主(zhu)要區別(bie)是(shi)能(neng)夠(gou)實現的溫度與濕度不同,從而(er)產(chan)生(sheng)的溫度也會有所不同,立(li)式(shi)的可(ke)以(yi)做(zuo)常溫以(yi)下(xia)的低溫和(he)干燥試(shi)(shi)(shi)(shi)驗(yan)而(er)臺(tai)(tai)式(shi)的只能(neng)做(zuo)常溫以(yi)上的溫度和(he)高(gao)濕試(shi)(shi)(shi)(shi)驗(yan)。
問(wen):那么什么樣的恒溫恒濕試驗(yan)箱性能(neng)是好(hao)的呢?
答(da):要問什么樣的(de)(de)恒溫恒濕(shi)箱性能是好(hao)的(de)(de),得從以下幾個(ge)方面去(qu)分析。
一、制(zhi)成試驗箱的(de)材質質量:
1.內箱材質(zhi):SUS304高級不銹鋼板(鏡面板);
2.外箱(xiang)材(cai)質(zhi):優(you)質(zhi)冷軋板表面噴涂;
3.保溫材質(zhi):超細玻璃纖維保溫棉;
4.加(jia)熱器:不銹鋼翅片式加(jia)熱管;
5.加濕器:不銹鋼加熱管;
二、恒溫恒濕(shi)箱制冷(leng)制熱(re)系統要求:
1.高(gao)效率(lv)、降低(di)測試(shi)成本、增長壽命(ming)、減(jian)低(di)故障(zhang)率(lv);
2.制冷(leng)機采(cai)用法國原裝"泰康(kang)"全封閉壓縮機;
3.冷凍系統采用單元式低溫(wen)回路系統設(she)計;
4.采用多(duo)翼式送風機強(qiang)力送風循環,避免任何死(si)角,可(ke)使測試區域內溫濕度分布均勻(yun);
5.風路(lu)循環出風回風設計,風壓風速(su)均符合測(ce)試標準,并可使(shi)開門瞬(shun)間(jian)溫濕度回穩(wen)時間(jian)快;
6.升溫、降溫、加濕系統要完全獨立;
小貼士:升溫(wen)加(jia)濕(shi)系(xi)統是如何工作的?
A.降溫是恒(heng)溫恒(heng)濕試(shi)驗(yan)箱(xiang)(xiang)重要(yao)環節,是判定(ding)一臺恒(heng)溫恒(heng)濕試(shi)驗(yan)箱(xiang)(xiang)性能好(hao)壞(huai)重要(yao)參數(shu),它包括壓縮機、冷(leng)凝器(qi)、節流裝置、蒸(zheng)發(fa)(fa)器(qi)四大組(zu)成。壓縮機是制(zhi)冷(leng)系(xi)統心(xin)臟,它吸(xi)(xi)入低溫低壓氣(qi)(qi)(qi)體(ti),變(bian)成高(gao)溫高(gao)壓氣(qi)(qi)(qi)體(ti),通(tong)(tong)過(guo)(guo)冷(leng)凝成液(ye)體(ti)放出熱(re)(re)量,通(tong)(tong)過(guo)(guo)風(feng)機帶走熱(re)(re)量,所以恒(heng)溫恒(heng)濕試(shi)驗(yan)箱(xiang)(xiang)下面是熱(re)(re)風(feng)原因,然(ran)后通(tong)(tong)過(guo)(guo)節流到(dao)為低壓液(ye)體(ti),其次通(tong)(tong)過(guo)(guo)蒸(zheng)發(fa)(fa)器(qi)成為低溫低壓氣(qi)(qi)(qi)體(ti)最后回到(dao)壓縮機;制(zhi)冷(leng)劑在(zai)蒸(zheng)發(fa)(fa)器(qi)中吸(xi)(xi)收(shou)熱(re)(re)量完成氣(qi)(qi)(qi)化(hua)過(guo)(guo)程重而吸(xi)(xi)收(shou)熱(re)(re)量,達(da)到(dao)制(zhi)冷(leng)目(mu)的(de),完成恒(heng)溫恒(heng)濕試(shi)驗(yan)箱(xiang)(xiang)降溫過(guo)(guo)程。
B。加(jia)濕(shi)(shi)裝(zhuang)置是(shi)控(kong)制恒(heng)溫恒(heng)濕(shi)(shi)試(shi)驗(yan)箱是(shi)不(bu)是(shi)升溫關鍵環(huan)節,它(ta)是(shi)控(kong)制器(qi)得到(dao)升溫指令時會輸出電(dian)(dian)(dian)壓給繼電(dian)(dian)(dian)器(qi),大約12伏直流電(dian)(dian)(dian)加(jia)在固(gu)態繼電(dian)(dian)(dian)器(qi)上面,它(ta)的(de)交流端(duan)相當(dang)于導線接通(tong)。接觸器(qi)也同時吸合,加(jia)熱(re)器(qi)兩端(duan)有電(dian)(dian)(dian)壓使(shi)其發熱(re),通(tong)過循環(huan)風機帶動(dong)把熱(re)量帶到(dao)箱里,使(shi)恒(heng)溫恒(heng)濕(shi)(shi)試(shi)驗(yan)箱升溫,那溫度快達到(dao)你的(de)設定(ding)。控(kong)制器(qi)通(tong)過加(jia)在固(gu)態繼電(dian)(dian)(dian)器(qi)通(tong)斷調節;我(wo)們在恒(heng)溫恒(heng)濕(shi)(shi)試(shi)驗(yan)箱看屏幕上加(jia)熱(re)出力多少來(lai)調節發熱(re)量。
三、安全(quan)保護系統(tong)配置要齊全(quan):
1.超溫保護裝置;
2.可程式(shi)恒溫恒濕(shi)試驗箱自動補水系統及缺水保護系統;
3.壓縮機(ji)(制(zhi)冷系統)高壓保護(hu);
4.壓(ya)縮機(制冷系統(tong))過(guo)電流保(bao)護(hu);
總結(jie):如果(guo)客戶所選購的恒溫恒濕試驗箱具備以上(shang)三個基本(ben)要求(qiu),那么我(wo)們就可以放心下(xia)單(dan),不必擔心自己購買的試驗箱質量(liang)和性(xing)能存在問題。
