  恒(heng)(heng)(heng)温(wen)(wen)恒(heng)(heng)(heng)湿(shi)机(ji)现(xian)在是(shi)较为常见的,尤其是(shi)一些(xie)大型(xing)工厂,但是(shi)恒(heng)(heng)(heng)温(wen)(wen)恒(heng)(heng)(heng)湿(shi)机(ji)也有(you)自己(ji)的小脾(pi)气,正如大家所知,任何(he)设备都不是(shi)非常完美的,多(duo)多(duo)少(shao)少(shao)会(hui)有(you)故(gu)障,那J9九游会AG 一起来(lai)看看恒(heng)(heng)(heng)温(wen)(wen)恒(heng)(heng)(heng)湿(shi)机(ji)的常见故(gu)障及解决办法吧!

  1.在(zai)高温(wen)(wen)试(shi)验(yan)中,如(ru)温(wen)(wen)度(du)变化达不(bu)到(dao)试(shi)验(yan)温(wen)(wen)度(du)值(zhi)时,可以检查电(dian)器(qi)系统,一(yi)(yi)一(yi)(yi)排除(chu)故障。如(ru)恒温(wen)(wen)恒湿试(shi)验(yan)箱温(wen)(wen)度(du)升得很(hen)慢(man),就(jiu)要(yao)查看(kan)风轮(lun)回(hui)系统,看(kan)一(yi)(yi)下风轮(lun)回(hui)的(de)调(diao)节挡板是(shi)否开启正常(chang),反之(zhi),就(jiu)检查风轮(lun)回(hui)的(de)电(dian)机运转是(shi)否正常(chang)。如(ru)温(wen)(wen)渡过(guo)冲(chong)厉害那(nei)么就(jiu)需要(yao)整定PID的(de)设置(zhi)参(can)数(shu)。假如(ru)温(wen)(wen)度(du)直(zhi)接(jie)上升,过(guo)温(wen)(wen)保护,那(nei)么,控制器(qi)出故障,须更(geng)换控制仪表(biao)或固体继电(dian)器(qi)。

  2.当恒(heng)温(wen)(wen)(wen)恒(heng)湿(shi)试(shi)验(yan)(yan)箱(xiang)低温(wen)(wen)(wen)达(da)不(bu)到(dao)试(shi)验(yan)(yan)的指标,那你就要观察温(wen)(wen)(wen)度(du)(du)的变化,是(shi)温(wen)(wen)(wen)度(du)(du)降(jiang)的很慢,仍是(shi)温(wen)(wen)(wen)度(du)(du)到(dao)一(yi)定(ding)值后温(wen)(wen)(wen)度(du)(du)有回升的趋(qu)势,前(qian)者就要检查(cha)一(yi)下,做(zuo)低温(wen)(wen)(wen)试(shi)验(yan)(yan)前(qian)是(shi)否将工(gong)作(zuo)(zuo)室(shi)烘干(gan)(gan),使工(gong)作(zuo)(zuo)室(shi)保持干(gan)(gan)燥后再将试(shi)验(yan)(yan)样(yang)品放(fang)入工(gong)作(zuo)(zuo)室(shi)内再做(zuo)试(shi)验(yan)(yan),工(gong)作(zuo)(zuo)室(shi)内的试(shi)验(yan)(yan)样(yang)品是(shi)否放(fang)置(zhi)的过多(duo),使工(gong)作(zuo)(zuo)室(shi)内的风不(bu)能充分轮回,在排除上述原因后,就要考虑是(shi)否是(shi)制冷系统(tong)中的故障.

  3.恒温恒湿试(shi)验(yan)(yan)箱在做湿热试(shi)验(yan)(yan)中(zhong),泛起实际湿度(du)会达(da)到100%或(huo)(huo)者实际湿度(du)与目标湿度(du)相差很大,数值低得很多,前者的(de)现象:可(ke)能是湿球(qiu)传感器上(shang)的(de)纱(sha)布干燥引(yin)起,那就要检查湿球(qiu)传感器的(de)水(shui)(shui)槽中(zhong)是否缺水(shui)(shui)。另(ling)一种可(ke)能就是湿球(qiu)纱(sha)布因(yin)(yin)使(shi)(shi)用(yong)时间长,或(huo)(huo)供水(shui)(shui)水(shui)(shui)质纯(chun)净度(du)的(de)原因(yin)(yin),会使(shi)(shi)纱(sha)布变硬,使(shi)(shi)纱(sha)布无法吸收(shou)水(shui)(shui)份而(er)干燥,只要更(geng)换或(huo)(huo)清(qing)洗纱(sha)布即可(ke)排除以(yi)上(shang)现象。

  4.恒(heng)(heng)温恒(heng)(heng)湿试验(yan)(yan)箱(xiang)设(she)(she)备在试验(yan)(yan)运行过程(cheng)中(zhong)溘(ke)然泛(fan)起(qi)故(gu)障时,控制(zhi)仪表上泛(fan)起(qi)对应的故(gu)障显(xian)示提(ti)示并(bing)有声讯报警提(ti)示。操(cao)纵员可以对照(zhao)设(she)(she)备的操(cao)纵使(shi)用(yong)中(zhong)的故(gu)障排(pai)除一章中(zhong)快(kuai)速(su)(su)检(jian)查出属于哪一类故(gu)障,即可请专(zhuan)业职员快(kuai)速(su)(su)排(pai)除故(gu)障,以确保试验(yan)(yan)的正常(chang)进行。其(qi)它(ta)(ta)环境试验(yan)(yan)设(she)(she)备在使(shi)用(yong)中(zhong)还会有其(qi)它(ta)(ta)的现象,那就要(yao)详(xiang)细(xi)现象,详(xiang)细(xi)分析和(he)排(pai)除。
