      故障一：恒溫恒濕試驗箱在濕熱試驗過程中，濕度達不到指定要求
，是哪裏出現問題?

      分析：恒溫恒濕試驗箱在做濕熱試驗中
，出現實際濕度會達到100%或者實際濕度與目標濕度相差很大

，數值低得很多，前者的現象：可ke能neng是shi濕shi球qiu傳chuan感gan器qi上shang的de紗sha布bu幹gan燥zao引yin起qi，那na就jiu要yao檢jian查zha濕shi球qiu傳chuan感gan器qi的de水shui槽cao中zhong是shi否fou缺que水shui
，水shui槽cao中zhong的de水shui位wei是shi由you一yi水shui位wei控kong製zhi器qi自zi動dong控kong製zhi的de，查zha水shui位wei控kong製zhi器qi供gong水shui係xi統tong是shi否fou供gong水shui正zheng常chang，水shui位wei控kong製zhi器qi工gong作zuo是shi否fou正zheng常chang。另ling一yi種zhong可ke能neng就jiu是shi濕shi球qiu紗sha布bu因yin使shi用yong時shi間jian長chang

，或huo供gong水shui水shui質zhi純chun淨jing度du的de原yuan因yin，會hui使shi紗sha布bu變bian硬ying

，使shi紗sha布bu無wu法fa吸xi收shou水shui份fen而er幹gan燥zao，隻zhi要yao更geng換huan或huo清qing洗xi紗sha布bu即ji可ke排pai除chu以yi上shang現xian象xiang。後hou者zhe的de現xian象xiang主zhu要yao是shi恒heng溫wen恒heng濕shi試shi驗yan箱xiang的de加jia濕shi係xi統tong不bu工gong作zuo，查zha看kan加jia濕shi係xi統tong的de供gong水shui係xi統tong，供gong水shui係xi統tong內nei是shi否fou有you一yi定ding的de水shui量liang，控kong製zhi加jia濕shi鍋guo爐lu水shui位wei的de水shui位wei控kong製zhi是shi否fou正zheng常chang，加jia濕shi鍋guo爐lu內nei的de水shui位wei是shi否fou正zheng常chang。如ru以yi上shang一yi切qie都dou正zheng常chang，那na就jiu要yao檢jian查zha電dian器qi控kong製zhi係xi統tong
，這zhe要yao請qing專zhuan業ye維wei修xiu人ren員yuan進jin行xing檢jian修xiu。
 

      故障二
，恒溫恒濕試驗箱低溫達不到指標，降溫很慢
，如何解決?

       分析：當dang恒heng溫wen恒heng濕shi試shi驗yan箱xiang低di溫wen達da不bu到dao試shi驗yan的de指zhi標biao，那na你ni就jiu要yao觀guan察cha溫wen度du的de變bian化hua

，是shi溫wen度du降jiang的de很hen慢man
，還hai是shi溫wen度du到dao一yi定ding值zhi後hou溫wen度du有you回hui升sheng的de趨qu勢shi，前qian者zhe就jiu要yao檢jian查zha一yi下xia，做zuo低di溫wen試shi驗yan前qian是shi否fou將jiang工gong作zuo室shi烘hong幹gan
，使shi工gong作zuo室shi保bao持chi幹gan燥zao後hou再zai將jiang試shi驗yan樣yang品pin放fang入ru工gong作zuo室shi內nei再zai做zuo試shi驗yan
，工gong作zuo室shi內nei的de試shi驗yan樣yang品pin是shi否fou放fang置zhi的de過guo多duo
，使shi工gong作zuo室shi內nei的de風feng不bu能neng充chong分fen循xun環huan，在zai排pai除chu上shang述shu原yuan因yin後hou
，就jiu要yao考kao慮lv是shi否fou是shi製zhi冷leng係xi統tong中zhong的de故gu障zhang了le，這zhe樣yang就jiu要yao請qing廠chang家jia的de專zhuan業ye人ren員yuan進jin行xing檢jian修xiu。後hou者zhe的de現xian象xiang是shi恒heng溫wen恒heng濕shi試shi驗yan箱xiang設she備bei的de使shi用yong環huan境jing不bu好hao所suo致zhi，設she備bei放fang置zhi的de環huan境jing溫wen度du，放fang置zhi的de位wei置zhi(箱體後與牆的距離)要滿足要求(在設備操作使用說明中都有規定)。
 

      故障三
，恒溫恒濕試驗箱在運行過程中

，溫度變化達不到試驗溫度值
，如何解決?

      分析：在zai高gao溫wen試shi驗yan中zhong，如ru溫wen度du變bian化hua達da不bu到dao試shi驗yan溫wen度du值zhi時shi，可ke以yi檢jian查zha電dian器qi係xi統tong

，逐zhu一yi排pai除chu故gu障zhang。如ru恒heng溫wen恒heng濕shi試shi驗yan箱xiang溫wen度du升sheng得de很hen慢man

，就jiu要yao查zha看kan風feng循xun環huan係xi統tong
，看kan一yi下xia風feng循xun環huan的de調tiao節jie擋dang板ban是shi否fou開kai啟qi正zheng常chang
，反fan之zhi，就jiu檢jian查zha風feng循xun環huan的de電dian機ji運yun轉zhuan是shi否fou正zheng常chang。如ru溫wen度du過guo衝chong厲li害hai那na麼me就jiu需xu要yao整zheng定dingPID的設置參數。如果溫度直接上升
，過溫保護，那麼控製器出故障，須更換控製儀表。
