冷熱沖擊試驗機

冷(leng)熱沖擊試驗機根(gen)據(ju)試驗需求(qiu)及測試標準分為三箱式和兩(liang)箱式，區別在于試驗方式和內部結(jie)構(gou)不同：

冷熱沖擊試驗機

功能(neng)不同溫(wen)段沖(chong)擊：由多(duo)級蒸(zheng)(zheng)發器結構相應(ying)切(qie)斷，控(kong)制蒸(zheng)(zheng)發面(mian)積與制冷量膨脹閥匹配，使用制冷系統輸出(chu)(chu)合理減少加熱(re)器中和的輸出(chu)(chu)量，達到恒定(ding)(ding)節(jie)能(neng)；另有獨立的換氣閥門，在(zai)排氣（常溫(wen)恢復）時動(dong)作引入(ru)環境(jing)空氣進氣口(kou)在(zai)環境(jing)溫(wen)度(du)曝露時吸(xi)進外面(mian)的空氣排氣口(kou)從機械室和試驗區(qu)排出(chu)(chu)熱(re)氣定(ding)(ding)時預定(ding)(ding)功能(neng)預先設定(ding)(ding)試驗開始時間，試驗箱自動(dong)開始起動(dong)并準備開始試驗。

冷(leng)熱沖(chong)擊試驗機(ji)操控系統毛病掃(sao)除操作手冊(ce)；雙門直冷(leng)式冷(leng)熱沖(chong)擊試驗機(ji)冬天壓(ya)縮機(ji)不易發動。

毛(mao)病現(xian)象：寒(han)冬天節，集成(cheng)電路三溫(wen)測試設備，一臺雙門直(zhi)冷式冷熱沖擊試驗機接上電源后壓縮機不發(fa)動。

毛病(bing)原因：維修人員用(yong)(yong)萬(wan)用(yong)(yong)表查看(kan)電(dian)源(yuan)及電(dian)氣系統各部件(jian)均正(zheng)常(chang)(chang)，唯(wei)發現溫(wen)(wen)控(kong)(kong)(kong)(kong)器(qi)(qi)旋(xuan)鈕(niu)置于“正(zheng)常(chang)(chang)”方位(wei)。雙(shuang)門(men)直(zhi)冷(leng)(leng)式冷(leng)(leng)熱(re)沖(chong)擊試(shi)驗機的(de)溫(wen)(wen)控(kong)(kong)(kong)(kong)器(qi)(qi)在冷(leng)(leng)藏(zang)(zang)室(shi)，由冷(leng)(leng)藏(zang)(zang)室(shi)溫(wen)(wen)度(du)改(gai)變通過溫(wen)(wen)控(kong)(kong)(kong)(kong)器(qi)(qi)操控(kong)(kong)(kong)(kong)壓縮(suo)機的(de)升、停。冷(leng)(leng)藏(zang)(zang)室(shi)溫(wen)(wen)控(kong)(kong)(kong)(kong)器(qi)(qi)的(de)控(kong)(kong)(kong)(kong)溫(wen)(wen)規模為(wei)0—10℃。通常(chang)(chang)溫(wen)(wen)控(kong)(kong)(kong)(kong)器(qi)(qi)控(kong)(kong)(kong)(kong)溫(wen)(wen)規模分(fen)為(wei)冷(leng)(leng)點(dian)、正(zheng)常(chang)(chang)點(dian)、熱(re)門(men)3檔(dang)，對應的(de)停、開機溫(wen)(wen)度(du)分(fen)則為(wei)0一(yi)3℃、4—6℃、7一(yi)l0℃。在冬(dong)天(tian)，也許呈現環(huan)境溫(wen)(wen)度(du)低于冷(leng)(leng)藏(zang)(zang)室(shi)溫(wen)(wen)度(du)，如為(wei)5℃，集成(cheng)電(dian)路(lu)測(ce)試(shi)設備，這時假如溫(wen)(wen)控(kong)(kong)(kong)(kong)器(qi)(qi)的(de)溫(wen)(wen)度(du)調理(li)旋(xuan)鈕(niu)調在正(zheng)常(chang)(chang)點(dian)方位(wei)，因為(wei)正(zheng)常(chang)(chang)點(dian)的(de)開機溫(wen)(wen)度(du)為(wei)6℃，而室(shi)溫(wen)(wen)只有5℃，所以壓縮(suo)機不(bu)能發動。此也闡明冬(dong)天(tian)雙(shuang)門(men)直(zhi)冷(leng)(leng)式冷(leng)(leng)熱(re)沖(chong)擊試(shi)驗機壓縮(suo)機不(bu)易(yi)發動的(de)道(dao)理(li)。

毛病掃除：將溫控器的溫度調理旋(xuan)(xuan)鈕旋(xuan)(xuan)至冷檔，集成電(dian)路三溫測試設備原理，冷熱沖擊(ji)試驗機(ji)康復(fu)正(zheng)常作業。

冷(leng)(leng)熱(re)沖(chong)擊(ji)試驗機(ji)發明廠有的(de)(de)在(zai)冷(leng)(leng)藏室裝上功率為15瓦左右的(de)(de)箱內(nei)加(jia)(jia)(jia)熱(re)絲(si)(si)(通常加(jia)(jia)(jia)熱(re)繞在(zai)冷(leng)(leng)藏室內(nei)膽的(de)(de)外(wai)側(ce))，壓縮機(ji)停(ting)機(ji)時(shi)，集(ji)成電路三溫測試設備公司，加(jia)(jia)(jia)熱(re)絲(si)(si)對冷(leng)(leng)藏室加(jia)(jia)(jia)熱(re)，以(yi)解決壓縮機(ji)發動與延(yan)伸(shen)運轉時(shi)間(jian)疑問(wen)。此外(wai)，在(zai)溫控器(qi)感溫管設置加(jia)(jia)(jia)熱(re)絲(si)(si)，壓縮機(ji)停(ting)機(ji)時(shi)加(jia)(jia)(jia)熱(re)絲(si)(si)對感溫管加(jia)(jia)(jia)熱(re)也能夠解決這個疑問(wen)。
