怎(zen)樣評估恒(heng)溫恒(heng)濕箱的優劣?

環境條件的再現性

  在試(shi)(shi)驗(yan)室內完整而(er)精l確(que)地再現自然界存在的環(huan)境(jing)條(tiao)件(jian)是可(ke)望而(er)不可(ke)及的事情。紫外光耐氣候試(shi)(shi)驗(yan)箱但(dan)是，在一(yi)定的容(rong)差范圍(wei)之內，人們(men)完全可(ke)以正確(que)而(er)近似(si)地模擬工(gong)程(cheng)產(chan)品(pin)(pin)在使用(yong)(yong)、貯存、運輸等過程(cheng)中所(suo)經受的外界環(huan)境(jing)條(tiao)件(jian)。這段(duan)話用(yong)(yong)工(gong)程(cheng)的語言概括，就是“試(shi)(shi)驗(yan)設備(bei)所(suo)創造的圍(wei)繞被試(shi)(shi)產(chan)品(pin)(pin)周邊(bian)的環(huan)境(jing)條(tiao)件(jian)（含平臺環(huan)境(jing)）紫外線老化試(shi)(shi)驗(yan)機應該(gai)滿足產(chan)品(pin)(pin)試(shi)(shi)驗(yan)規(gui)范所(suo)規(gui)定的環(huan)境(jing)條(tiao)件(jian)及其容(rong)差的要(yao)求”。

怎樣維護高低溫試驗箱中(zhong)的(de)壓縮機

1、由于壓縮機有(you)(you)空(kong)氣循環系統(tong)，復合(he)鹽(yan)霧試驗機定做，如果(guo)設備周圍環境的空(kong)氣灰塵多，需(xu)加過濾裝置，同時，空(kong)氣中是絕l對不允許含有(you)(you)可(ke)燃氣體(ti)及腐(fu)蝕性(xing)氣體(ti)的，以免可(ke)能引起爆l炸或內部銹蝕。整體(ti)來講，要保(bao)證空(kong)氣的相(xiang)對濕度較低，復合(he)式鹽(yan)霧試驗機，灰常少量，通風(feng)良好。

2、壓(ya)縮的性(xing)能不宜受高溫(wen)，環境溫(wen)度(du)低于30℃為宜。如果溫(wen)度(du)過(guo)高，壓(ya)縮機的輸出空(kong)氣量就會減(jian)少。
