真空(kong)甩帶(dai)爐(lu)(lu)恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)怎么(me)測定(ding)
真空(kong)甩帶(dai)爐(lu)(lu)的(de)(de)(de)恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)均勻(yun)(yun)(yun)性,是保(bao)(bao)(bao)證(zheng)(zheng)熱(re)(re)處(chu)(chu)理(li)工(gong)藝需(xu)求(qiu)、保(bao)(bao)(bao)證(zheng)(zheng)熱(re)(re)處(chu)(chu)理(li)產(chan)品(pin)(pin)(pin)品(pin)(pin)(pin)質、提(ti)高(gao)生產(chan)率的(de)(de)(de)重要(yao)保(bao)(bao)(bao)障(zhang)。發熱(re)(re)元件(jian)布(bu)置(zhi),通常有(you)圓形布(bu)置(zhi)和(he)(he)矩形布(bu)置(zhi)。
真空(kong)甩帶(dai)爐(lu)(lu)在(zai)(zai)真空(kong)狀態下加熱(re)(re),熱(re)(re)傳(chuan)導方(fang)式只(zhi)有(you)輻射。恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)的(de)(de)(de)測量,通常是在(zai)(zai)空(kong)載狀態下進行的(de)(de)(de)。恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)的(de)(de)(de)存在(zai)(zai),是為了保(bao)(bao)(bao)證(zheng)(zheng)熱(re)(re)處(chu)(chu)理(li)工(gong)藝需(xu)要(yao),保(bao)(bao)(bao)證(zheng)(zheng)熱(re)(re)處(chu)(chu)理(li)產(chan)品(pin)(pin)(pin)品(pin)(pin)(pin)質,提(ti)高(gao)生產(chan)率。恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)的(de)(de)(de)判斷標準(zhun)很多,不同行業(ye)按照各自行業(ye)需(xu)求(qiu),判斷各自的(de)(de)(de)恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)。
每一臺真空(kong)甩帶(dai)爐(lu)(lu)通常都是按照恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)尺(chi)寸要(yao)求(qiu)設計的(de)(de)(de),合格的(de)(de)(de)真空(kong)熱(re)(re)處(chu)(chu)理(li)爐(lu)(lu),都得滿(man)足(zu)恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)尺(chi)寸要(yao)求(qiu)。爐(lu)(lu)內(nei)(nei)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)均勻(yun)(yun)(yun)性,是指爐(lu)(lu)內(nei)(nei)設計恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)邊緣各測試點(dian)高(gao)和(he)(he)低與控(kong)(kong)制(zhi)點(dian)的(de)(de)(de)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)偏差(cha)。為了保(bao)(bao)(bao)證(zheng)(zheng)工(gong)藝溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)和(he)(he)實(shi)際記錄溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)的(de)(de)(de)一致(zhi)性,在(zai)(zai)選擇(ze)控(kong)(kong)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)熱(re)(re)電(dian)(dian)偶(ou)(ou)(ou)時,按照熱(re)(re)電(dian)(dian)偶(ou)(ou)(ou)的(de)(de)(de)測溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)范圍應盡量選擇(ze)誤差(cha)小、精度(du)等級高(gao)的(de)(de)(de);其次選擇(ze)帶(dai)冷端(duan)補償(chang)的(de)(de)(de)控(kong)(kong)制(zhi)儀(yi)(yi)表,以(yi)保(bao)(bao)(bao)證(zheng)(zheng)工(gong)作(zuo)偶(ou)(ou)(ou)與爐(lu)(lu)內(nei)(nei)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)一致(zhi)。
另(ling)外(wai),應當(dang)盡可能地將(jiang)控(kong)(kong)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)熱(re)(re)電(dian)(dian)偶(ou)(ou)(ou)安裝在(zai)(zai)爐(lu)(lu)內(nei)(nei)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)近似于平(ping)均爐(lu)(lu)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)值的(de)(de)(de)地方(fang),以(yi)便(bian)正(zheng)確地反映(ying)真空(kong)熱(re)(re)處(chu)(chu)理(li)爐(lu)(lu)的(de)(de)(de)恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)的(de)(de)(de)均勻(yun)(yun)(yun)性。
通常,真空(kong)甩帶(dai)爐(lu)(lu)恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)區(qu)(qu)(qu)均勻(yun)(yun)(yun)性的(de)(de)(de)測定(ding)裝置(zhi):測溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)熱(re)(re)電(dian)(dian)偶(ou)(ou)(ou)、補償(chang)導線、檢(jian)測儀(yi)(yi)表(如(ru)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)巡(xun)檢(jian)儀(yi)(yi))、測溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)(wen)架等組成(cheng)。以(yi)上就是今天的(de)(de)(de)內(nei)(nei)容分享,如(ru)果(guo)您有(you)需(xu)要(yao)咨詢的(de)(de)(de),歡迎撥打電(dian)(dian)話。
