[恒溫恒濕試驗箱]如何控制恒溫恒濕試(shi)驗箱(xiang)內部溫度(du)與(yu)濕度(du)?
恒(heng)(heng)溫(wen)(wen)恒(heng)(heng)濕試(shi)(shi)驗箱是試(shi)(shi)樣放在規定的(de)(de)溫(wen)(wen)度(du)(du)及(ji)濕度(du)(du),看試(shi)(shi)樣的(de)(de)耐高(gao)溫(wen)(wen),耐低溫(wen)(wen),以及(ji)抗濕度(du)(du)才(cai)能(neng),那(nei)么(me)恒(heng)(heng)溫(wen)(wen)恒(heng)(heng)濕試(shi)(shi)驗機一起具(ju)有(you)加(jia)溫(wen)(wen),降(jiang)溫(wen)(wen),加(jia)濕,降(jiang)濕才(cai)能(neng)。在日常運(yun)用恒(heng)(heng)溫(wen)(wen)恒(heng)(heng)濕試(shi)(shi)驗箱做實(shi)(shi)驗的(de)(de)時(shi)分,要對恒(heng)(heng)溫(wen)(wen)恒(heng)(heng)濕箱內(nei)部溫(wen)(wen)度(du)(du)與濕度(du)(du)進行操控,以保(bao)證非常好的(de)(de)實(shi)(shi)驗成果。那(nei)么(me)要操控恒(heng)(heng)溫(wen)(wen)恒(heng)(heng)濕箱內(nei)部溫(wen)(wen)度(du)(du)與濕度(du)(du),具(ju)體有(you)什么(me)辦法(fa)呢?
首要有兩種辦法:
◆加溫操控
一、恒(heng)溫(wen)恒(heng)濕試驗箱首要靠加溫(wen)設(she)備升溫(wen)。
二、加溫(wen)設備(bei):加溫(wen)設備(bei)是(shi)(shi)操控恒溫(wen)恒濕機(ji)是(shi)(shi)不是(shi)(shi)升溫(wen)關鍵環(huan)節(jie);它是(shi)(shi)操控器(qi)得到升溫(wen)指令時會輸出電(dian)壓(ya)給繼電(dian)器(qi),具體步驟(zou):
1、導線接(jie)通的溝通端;
2、電器(qi)靠操控器(qi)輸(shu)(shu)入電壓(ya),輸(shu)(shu)入電壓(ya)大概3-12伏;
3、恒溫恒濕試驗箱靠經過循環(huan)風(feng)機(ji)股(gu)動把(ba)熱量帶到箱內升溫。
4、加(jia)熱器(qi)兩端電(dian)壓(ya)使吸合觸器(qi)發熱;
三、溫(wen)度快到達(da)設(she)定值時(shi),操控器經過加在固態繼電器通(tong)斷(duan)調理 。
四、調理(li)發熱量:
1、89度以(yi)下溫度操控;
2、89度(du)以上(shang)溫度(du)操控(kong)首要(yao)靠(kao)在恒溫恒濕試驗箱看屏(ping)幕上(shang)加熱出力多少(shao)來(lai)調理發熱量。
①在(zai)一邊經過固(gu)態(tai)繼電(dian)器發熱出力多少(shao);
②經過壓(ya)縮機制冷循環降溫到達動態平衡,溫度穩定。
◆降溫(wen)操控:降溫(wen)是恒(heng)溫(wen)恒(heng)濕機重要環節,是斷定一(yi)臺(tai)恒(heng)溫(wen)恒(heng)濕機功能好壞(huai)重要參數(shu)
一、恒(heng)溫恒(heng)濕試驗(yan)箱功能(neng)好壞的判(pan)斷(duan)首要依據降溫才能(neng)來;
二、制(zhi)冷(leng)劑在蒸發器中吸收熱(re)量完(wan)結氣化進程重而(er)吸收熱(re)量,到達制(zhi)冷(leng)意(yi)圖,完(wan)結恒溫恒濕試驗箱降溫進程。
三、經過(guo)冷(leng)凝成液體放出(chu)熱量,風機帶走熱量,致使(shi)恒(heng)溫恒(heng)濕試驗箱下面熱風,再經過(guo)節省(sheng)到為低(di)壓(ya)液體,其次經過(guo)蒸(zheng)發器(qi)成為低(di)溫低(di)壓(ya)氣體最終回到壓(ya)縮機;
四、壓(ya)縮機(ji)吸入低溫(wen)低壓(ya)氣(qi)體,成為高(gao)溫(wen)高(gao)壓(ya)氣(qi)體系屬(shu)冷系統(tong)首要組件;
五、恒溫恒濕(shi)試驗箱(xiang)由壓縮機、冷(leng)凝器、節(jie)省設備、蒸發器四大組(zu)成;
以上即是恒(heng)溫恒(heng)濕試驗箱(xiang)內部溫度與濕度的兩(liang)種首要控制的辦法。希(xi)望能有助(zhu)您對恒(heng)溫恒(heng)濕試驗箱(xiang)更近一步的了(le)解。
