恒温(wen)(wen)恒湿试验箱是产品放在规定的温(wen)(wen)度(du)及湿度(du),看产品的耐(nai)高(gao)温(wen)(wen),耐(nai)低温(wen)(wen),以及抗湿度(du)能(neng)力(li),那(nei)么恒温(wen)(wen)恒湿试验箱同时(shi)具备加温(wen)(wen),降(jiang)温(wen)(wen),加湿,降(jiang)湿能(neng)力(li)。

       

升(sheng)温(wen)(wen)(wen)设(she)备是(shi)操纵(zong)恒(heng)温(wen)(wen)(wen)恒(heng)湿(shi)试验箱(xiang)是(shi)否(fou)提温(wen)(wen)(wen)重要环节(jie);它(ta)是(shi)控制(zhi)板(ban)获得(de)提温(wen)(wen)(wen)命令时候输出(chu)电(dian)压给汽车继电(dian)器,大(da)概3-12伏交(jiao)流(liu)(liu)电(dian)加(jia)(jia)在(zai)(zai)中(zhong)间继电(dian)器上(shang)边;它(ta)的(de)沟(gou)通交(jiao)流(liu)(liu)端等于输电(dian)线接(jie)入;交(jiao)流(liu)(liu)接(jie)触器也另外吸合,电(dian)加(jia)(jia)热(re)(re)器两边有工(gong)作电(dian)压使(shi)其发烫(tang)(tang),根(gen)据循环系统离心风机推动把(ba)发热(re)(re)量送到箱(xiang)内(nei),使(shi)恒(heng)温(wen)(wen)(wen)恒(heng)湿(shi)试验箱(xiang)提温(wen)(wen)(wen),那溫(wen)度(du)(du)快做到你的(de)预(yu)设(she)值;控制(zhi)板(ban)根(gen)据加(jia)(jia)在(zai)(zai)中(zhong)间继电(dian)器导通调整(zheng);我们在(zai)(zai)恒(heng)温(wen)(wen)(wen)恒(heng)湿(shi)试验箱(xiang)看(kan)显示(shi)屏上(shang),加(jia)(jia)温(wen)(wen)(wen)负荷(he)(he)率是(shi)多(duo)少来(lai)调整(zheng)热(re)(re)值;它(ta)是(shi)在(zai)(zai)89度(du)(du)之上(shang)温(wen)(wen)(wen)控,在(zai)(zai)89度(du)(du)下(xia)列溫(wen)度(du)(du)平稳怎样(yang)操纵(zong)呢?恒(heng)温(wen)(wen)(wen)恒(heng)湿(shi)试验箱(xiang)是(shi)在(zai)(zai)一边根(gen)据中(zhong)间继电(dian)器发烫(tang)(tang)负荷(he)(he)率是(shi)多(duo)少;另根(gen)据制(zhi)冷压缩机制(zhi)冷循环减温(wen)(wen)(wen)做到稳定平衡(heng);溫(wen)度(du)(du)稳定。

  减温(wen)(wen)是恒(heng)(heng)(heng)温(wen)(wen)恒(heng)(heng)(heng)湿试(shi)验箱(xiang)关键步(bu)骤,是判断(duan)一台恒(heng)(heng)(heng)温(wen)(wen)恒(heng)(heng)(heng)湿试(shi)验箱(xiang)特(te)性(xing)优劣关键主要参数,它(ta)包含(han)制冷(leng)压缩(suo)机(ji)(ji)、冷(leng)却器(qi)、节流装置、空调蒸发(fa)器(qi)四大构成。制冷(leng)压缩(suo)机(ji)(ji)是制冷(leng)机(ji)(ji)组心血管,它(ta)吸进(jin)低(di)温(wen)(wen)底(di)(di)压汽体(ti)(ti),变为(wei)超(chao)高(gao)压汽体(ti)(ti),根据(ju)(ju)冷(leng)疑成液体(ti)(ti)释放发(fa)热(re)量,根据(ju)(ju)离心风(feng)机(ji)(ji)带去发(fa)热(re)量,因此恒(heng)(heng)(heng)温(wen)(wen)恒(heng)(heng)(heng)湿试(shi)验箱(xiang)下边是暧风(feng)原因,随后根据(ju)(ju)节流阀到为(wei)底(di)(di)压液体(ti)(ti),次之根据(ju)(ju)空调蒸发(fa)器(qi)变成低(di)温(wen)(wen)底(di)(di)压汽体(ti)(ti)后面(mian)返回制冷(leng)压缩(suo)机(ji)(ji);冷(leng)媒在空调蒸发(fa)器(qi)中消(xiao)化(hua)吸收发(fa)热(re)量进(jin)行汽化(hua)全过程重(zhong),而消(xiao)化(hua)吸收发(fa)热(re)量,做到致冷(leng)目(mu)地(di),进(jin)行恒(heng)(heng)(heng)温(wen)(wen)恒(heng)(heng)(heng)湿试(shi)验箱(xiang)减温(wen)(wen)全过程。
  加湿(shi)系(xi)统(tong)与加热(re)系(xi)统(tong)大致一样;它是加热(re)器加热(re)水变成蒸(zheng)汽过程;完(wan)成恒(heng)温恒(heng)湿(shi)试(shi)验(yan)箱(xiang)加湿(shi)目的。

  降湿系统也是靠制冷系统完成,蒸发器放在恒温恒湿试验箱里面;比较冷,恒温恒湿试验箱里面高湿气体会见冷的物体冷凝成液体;如此反复箱体的高湿气体会很少,达到降湿目的。出现湿度不稳定 ,高低温达不到,请联系专业技术员进行恒温恒湿试验箱维修
