Yuav ua li cas kom paub qhov txawv ntawm qhov zoo thiab tsis zoo ntawm K hom thermocouple
Qhov zoo thiab tsis zoo ntawm K-hom thermocouples yog dab tsi? Nyob rau hauv cov ntaub ntawv ntawm
Thermocouple nyob rau hauv kev siv ntawm cov txheej txheem feem ntau ntsib yuav ntsib kev txaj muag tshaj plaws, uas yog, qhov zoo thiab tsis txawv txav ntawm lub thermocouple, tsis txhob saib qhov teeb meem me me no tau txais koj blushing, ob peb hnub dhau los nyob rau hauv ib lub lag luam, lub lag luam nyob rau hauv kev coj noj coj ua ntawm kev soj ntsuam, tsuas yog ib tug phooj ywg txuas nrog thermocouple, tab sis vim muaj teeb meem zoo thiab tsis zoo. Tus nais hais kom nws cov hauv paus hniav zoo thiab tsis zoo li cas? Nws xav tau ntev, tsis tuaj yeem hais qhia. Thaum kawg, nws ib txwm siv txoj kev los xyuas txog qhov zoo thiab tsis zoo thermocouple, nws tseem tsis tuaj yeem teb, vim tias cov tuam ntxhab tsis qhia qhov khoom ntawm lub hoobkas ua rau ntau tus tswv ntawm lub lag luam tsis tuaj yeem paub tseeb uas yog lub cathode, uas yog qhov tsis zoo, Niaj hnub no mus rau ib tug phooj ywg hais ib yam dab tsi, yog li tsis mus ntsib thaum maj, cov lus hauv qab no tham txog: nickel-chromium - nickel silicon thermocouple
Cia kuv tham txog cov tsis muaj cov nickel-chromium-nickel silicon thermocouple
Nickel-chromium-nickel-silicon thermocouple (K-hom thermocouple) yog tam sim no nyob rau hauv 500 ℃ saum toj ntawm qhov ntsuas kub ntawm tus nqi ntau tshaj ntawm cov thermocouple pheej yig, tus nqi ntawm lwm cov thermocouple cov hlau.
Cov tshuaj hu ua "electrode" (KP) yog Ni: Cr ≈ 90: 10, cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov tsis zoo electrode (KN) yog Ni: Sika97: nws siv qhov kub ntau yog -20 1100 (1300) .
K-hom thermocouple nrog linearity zoo, siab thermoelectromotive quab yuam, siab rhiab heev, stability stability thiab uniformity, muaj zog oxidation kuj, pheej yig, etc., yuav siv tau rau oxidizing, inert cua. Cov K-hom thermocouples tsis tuaj yeem siv ncaj qha rau cov muaj dej sov rau cov dej cawv, txo lossis txo, oxidising alternating atmospheres thiab hauv lub tshuab nqus tsev, thiab tsis pom zoo siv rau hauv qhov chaw tsis muaj zog oxidized atmospheres.
Hais rau cov xaim hluav taws xob nickel-chromium-nickel-silicon thermocouple: nickel-chromium-nickel-silicon (nickel-aluminium) thermocouple (sub-naj npawb K) ntawm qhov zoo electrode yog chromium 10% nickel-chromium alloy (KP) 3% nickel-silicon alloy (KN). , Raws li qhov no feature, nrog cov hlau nplaum yuav yooj yim nrhiav thermocouple zoo thiab tsis zoo. Nws yog tsi ntsees los ntawm kev siv ntau yam kub, kev ruaj khov ntawm kev kub ntxhov, thermoelectromotive quab yuam thiab kub ntawm txoj kev sib raug zoo ntawm txoj kev sib raug zoo ntawm cov kwv yees, pheej yig, yog li tam sim no, qhov tam sim no yog qhov ntau ntawm cov thermocouple, nickel chromium - xee thickocouple, K hom Thermocouples yog tsim rau nruam siv nyob rau hauv oxidizing thiab inert atmospheres. Kev siv lub sijhawm luv luv ntawm 1300 ℃, siv lub sijhawm ntev ntawm 1100 ℃. Tom qab xaiv K-hom thermocouple zoo siv los ua ib qho qauv rau kev ua hauj lwm nrog cov qe menyuam ua si nrog nickel-chromium-nickel thiab lwm cov thawv hlau thermocouple, hauv no thermocouple ntxiv cov yttrium hlau thiab magnesium thiab lwm cov ntsiab lus, antioxidant cov khoom muaj peev xwm yuav ntxiv tuaj, Qhov siab tshaj plaws ntawm qhov kub kub ncav cuag tau mus txog 1300 ℃. Txhawm rau muab tag nrho cov kev ua si mus rau qhov zoo ntawm pheej yig pheej yig hlau, hauv tib qhov ntsuas qhov chaw, koj tuaj yeem nruab ib ob peb thermocouples, siv nws cov kev siab thiab thermoelectric cov khoom ntawm cov yam ntxwv ntawm kev txhim kho linearity mus rau lub hom phiaj ntawm qhov tseeb ntsuas, K-hom thermocouple yog antioxidant Ib lub hauv paus muaj zog thermocouple. Tsis haum rau lub tshuab nqus tsev, cov roj, cov khoom xyaw cua thiab oxidation thiab txo ntawm qhov chaw ntawm kev siv cov liab qab. Thaum cov pa ib feem tsawg tsawg, cov nickel chrome hauv chromium yuav zoo oxidation (tseem hu ua ntsuab yaig), kom cov thermoelectromotive quab yuam tau hloov ntau heev. Tab sis qhov tshwm sim ntawm cov pa roj ntawm qhov tshaj li Yog li, kev siv hlau thermocouple tiv thaiv tube.
Tam sim no kuv xav qhia rau koj tias thermocouple zoo li cas thiab tsis pom zoo: Ua ntej, nickel-chromium-nickel silicon thermocouple ob kab muaj cuab kev txawv xim, muaj ntsuab, ib yog grey, ntsuab rau qhov zoo, yog Yog qhov armored thermocouple hlau, koj siv tau cov khoom sib nqus me, ntawm qhov tsis zoo, uas yog, qhov chaw xaim grey saum cov xaim, yog tias muaj qhov tsis zoo Qhov no yog tam sim no siv nickel-chromium - nickel silicon thermocouple scene ntau heev, tab sis ntau zoo dua Tus neeg hloov lub nickel-chromium-nickel-aluminium thermocouple nrog ib tug nickel-chromium-nickel silicon thermocouple. Tab sis kuj tseem muaj qee cov neeg siv qub los yog kev siv tawm txawv teb chaws los ntawm nickel-chromium-nickel txhuas thermocouple. Txawm hais tias cov tshuaj lom neeg muaj pes tsawg leeg ntawm ob lub thermocouples sib txawv, tab sis cov thermoelectric cov khoom ntawm tib yam, siv tib lub rooj index.
