[恒溫恒濕試驗箱]恒溫恒濕試驗箱用戶可自行解(jie)決的故障方法
有(you)關恒(heng)溫恒(heng)濕試(shi)(shi)驗(yan)箱(xiang)故(gu)(gu)障排(pai)除與(yu)解(jie)決(jue)方案的(de)技術文獻已(yi)經是(shi)(shi)老生常談的(de)事情了,但(dan)由于(yu)恒(heng)溫恒(heng)濕試(shi)(shi)驗(yan)箱(xiang)是(shi)(shi)一項(xiang)專業(ye)技術的(de)產品,也是(shi)(shi)一種高端精密的(de)檢測儀(yi)器(qi),所(suo)以(yi),很多用戶(hu)寧愿報修等廠家上門(men)來處理,也不(bu)會自行(xing)動手解(jie)決(jue),因為用戶(hu)缺乏(fa)專業(ye)技能與(yu)專業(ye)指(zhi)導,本文章將重(zhong)點講(jiang)述的(de)是(shi)(shi)恒(heng)溫恒(heng)濕試(shi)(shi)驗(yan)箱(xiang)用戶(hu)可自行(xing)解(jie)決(jue)的(de)濕熱系統(tong)故(gu)(gu)障,幫(bang)助(zhu)您在試(shi)(shi)驗(yan)箱(xiang)出現(xian)故(gu)(gu)障時能以(yi)最(zui)快的(de)時間恢復正(zheng)常使用。
一、濕(shi)(shi)度(du)顯示100%或做(zuo)低濕(shi)(shi)點時,濕(shi)(shi)度(du)下(xia)不來
自(zi)行解(jie)決方案(an)1:干濕球紗(sha)布(bu)掛(gua)錯位置,上面一支傳(chuan)感器為干球,下面一支傳(chuan)感器為濕球,正常(chang)情況下,必須將紗(sha)布(bu)掛(gua)在(zai)(zai)下面的(de)一支傳(chuan)感器上,且紗(sha)布(bu)下端(duan)必須可(ke)靠的(de)浸(jin)在(zai)(zai)積水頭水槽內(nei),以便濕球紗(sha)布(bu)能可(ke)靠的(de)吸水。
自行解決方案2:濕(shi)(shi)球紗(sha)布發黃(huang),或者使(shi)用時間過久,紗(sha)布上(shang)積淀太多礦物質,導致濕(shi)(shi)球紗(sha)布吸(xi)水(shui)性能下降,吸(xi)不上(shang)水(shui),從而使(shi)檢測到的濕(shi)(shi)度不準(zhun)確,造成濕(shi)(shi)度偏高(gao)的假(jia)像(xiang);
自行解決方案3:濕球(qiu)水(shui)(shui)槽中無水(shui)(shui)或(huo)水(shui)(shui)位(wei)偏低,紗布吸(xi)不(bu)到水(shui)(shui),重點檢查(cha)以下幾個部位(wei):
a.觀察水(shui)槽邊的水(shui)位盒(he)是(shi)否有(you)(you)水(shui),如果沒有(you)(you),有(you)(you)可(ke)能(neng)為浮(fu)球損壞;
b.電(dian)(dian)磁泵損壞(huai),用萬(wan)用表(biao)的電(dian)(dian)壓檔測量(liang)其阻值(zhi),如果開路則損壞(huai);
c.間隙補(bu)水計時器損壞,無法正常補(bu)水
二、濕度(du)上(shang)升慢或者根本升不上(shang)去
自(zi)行解決(jue)方案1:查(cha)看控制器(qi)上濕度(du)OUT是否有輸出(chu),或者100%輸出(chu);
自行解決方案2:查看SSR2信(xin)號燈是(shi)否點亮(liang),如有點亮(liang),則可(ke)以用(yong)鉗形(xing)表測量(liang)一下電流;如果沒有電流,則有可(ke)能是(shi)下列幾種原因:a.FQ2斷路(lu)器跳脫(tuo),切斷了加熱通路(lu);加濕固態繼電器SSR損壞,有信(xin)號輸入但不能導通;加濕管損壞;
三、水箱缺水
自行解決方案1:水箱水位不(bu)夠,需手動加水,加水時注(zhu)意看水位標(biao),防止水位太高溢(yi)水;
自(zi)行解決(jue)方案2:水箱浮球損(sun)壞,以下圖片(pian)為正常情況下的顯(xian)示,如(ru)果(guo)翻轉后一(yi)直(zhi)處(chu)導通(tong)狀(zhuang)態或一(yi)直(zhi)處(chu)于斷開狀(zhuang)態,則浮球損(sun)壞,需更(geng)換;
四、如果恒溫恒濕(shi)(shi)(shi)試(shi)驗箱(xiang)的控制器上(shang)濕(shi)(shi)(shi)度(du)(du)信(xin)(xin)號(hao)(hao)有輸(shu)入,但SSR上(shang)的信(xin)(xin)號(hao)(hao)指示(shi)燈并不(bu)亮,自行(xing)解決方案(an);則需重點檢查加(jia)(jia)濕(shi)(shi)(shi)水盤(或加(jia)(jia)濕(shi)(shi)(shi)鍋爐)水位檢測浮(fu)球(qiu)(qiu)(qiu),查看浮(fu)球(qiu)(qiu)(qiu)是(shi)因為水位不(bu)夠(gou)未浮(fu)起(qi),還是(shi)水位夠(gou)了(le),但浮(fu)球(qiu)(qiu)(qiu)損壞(huai)造成不(bu)動作,從面導致加(jia)(jia)濕(shi)(shi)(shi)信(xin)(xin)號(hao)(hao)無號(hao)(hao)送(song)達SSR上(shang),無法加(jia)(jia)濕(shi)(shi)(shi);如果有兩支(zhi)以上(shang)加(jia)(jia)濕(shi)(shi)(shi)管,檢查一(yi)下(xia)是(shi)否有部分加(jia)(jia)濕(shi)(shi)(shi)管沒有工作,造成加(jia)(jia)濕(shi)(shi)(shi)能力(li)不(bu)夠(gou),試(shi)驗溫濕(shi)(shi)(shi)度(du)(du)點剛(gang)好(hao)在高濕(shi)(shi)(shi)低(di)濕(shi)(shi)(shi)切換點上(shang),除濕(shi)(shi)(shi)能力(li)過大(da),造成濕(shi)(shi)(shi)度(du)(du)升不(bu)上(shang)去,需將情(qing)況及時反饋廠方,由(you)廠方提供技(ji)術支(zhi)持,更改或升級參數(shu)。
