Qhov sib txawv ntawm cov cuab yeej thermocouple thiab huab cua kub cua sov rauv thermocouple

Lub thermoelectric muaj peev xwm ntawm lub caj npab thermocouple yuav nce raws li qhov ntsuas kub ntawm kev ntsuas qhov kawg nce. Qhov loj ntawm cov thermoelectric muaj peev xwm tsuas yog cuam tshuam nrog cov khoom ntawm Thermocouple tus neeg xyuas thiab qhov kub thiab txias ntawm ob xaus, thiab tsis muaj dab tsi ua rau qhov ntev thiab txoj kab uas hla ntawm thermoelectrode.

Qhov ob xaus ntawm cov neeg saib xyuas ntawm ob qho sib txawv yog welded los ua lub voj. Qhov ntsuas kub ncaj qha yog hu ua kev ua haujlwm kawg, thiab lub davhlau ya nyob xaus yog hu ua qhov xaus txias, tseem hu ua qhov kawg kawg. Thaum muaj qhov sib txawv kub ntawm qhov ua haujlwm kawg thiab qhov siv kawg, ib qho cua sov tam sim no yuav tsim tawm hauv lub voj. Thaum cov twj tso tawm ntawm cov twj tso tawm, tus nqi kub sib haum ntawm lub thermoelectric peev xwm tsim los ntawm Thermocouple yuav qhia ntawm qhov ntsuas.

Cov tau txais kev thov thiab kev ua haujlwm kub:
Thaum muaj cov pa roj hluav taws xob muaj cov phosphide, sab nraud ntawm cov pob khoom zoo nkauj silicon carmide carbide tiv thaiv los ntawm kev qhia German technology. Lub porosity ntawm cov khoom no yog ze rau xoom. Nws muaj huab cua siab nruj, oxidation ua hauj lwm zoo thiab corrosion tsis kam; tsis tshua muaj neeg tawv tawv, hnav tsis kam; Lub zog siab, thiab lub zog nce nrog qhov nce ntawm kub. Nws cais cov xeb thiab yaig ntawm ntau qhov kub kub ua rau muaj kev phom sij, thiab tuaj yeem siv rau lub sijhawm ntev dhau ntawm 1420 degree.
Thaum cov roj tsis muaj cov phosphides, sab nraud casing substrate yog ua los ntawm cov cua sov-resistant alloy hlau. Los ntawm kev siv cov thev naus laus zis txhim kho kev kho siab heev, 0. 5 ~ 1.2mm tuab cov khoom hlau-ceramic txheej khoom yog tsim nyob rau saum npoo ntawm cov hlau casing. Cov khoom siv txheej txheej muaj cov yam ntxwv ntawm hardness (nce txog hv1450), siab ntom ntom (≥99.5%), porosity (<0.5%), strong bonding with the substrate (≥75MPa), and good high-temperature wear resistance and corrosion resistance. The thermal barrier effect of the coating allows the protective casing to be used for a long time under working conditions of about 1300℃. The difference between armored thermocouples and hot air furnace thermocouples
Cov Tes Tes Hauv Sab Hauv Cov Khoom Siv Corundum tiv thaiv raj los muab kev ntsuas kom huv si rau cov platinum geranium hlau. Sab hauv thiab txheej tsho yog ntim nrog Ceramic Micramic nrog rau kev co kom txo tau lub sijhawm siv.

Thermocouples rau kub ntshiab rauv taws hauv cov steel nroj tsuag hauv kev lag luam steel nyob rau hauv kev lag luam steel hauv cov huab cua kub rau cov txheej txheem smelting. Lub dome kub ua haujlwm ntawm qhov kub ntawm 1200 ~ 1250 degree rau lub sijhawm ntev, thiab muaj kev kub siab tshaj plaws tuaj yeem ncav cuag thaum cov txheej txheem kev ua kom muaj zog. Vim tias cov sib txawv ntawm cov khoom siv sib txawv los ntawm ntau yam lag luam, kev nyiam huv ntawm cov roj av uas tsim tawm kuj txawv. Thaum lub sijhawm cov txheej txheem combusion ntawm lub tshuab kub kub tawg, feem ntau yog leej faj, phosphorus thiab lwm yam sib txuas. Thermocouple kev tiv thaiv tes dej yuav tsum tau tiv taus qhov siab-airflow yaig, particle hnav thiab kub-roj av corrosion. Kev tiv thaiv thermocouple thermocouple, molybdenum disitic, thiab lwm yam kev sib kis hlau thiab corrosion thiab corrosion vim kub-kub ua rau lub zog. Qhov kev pabcuam lub neej ntawm thermocouple yog luv thiab tsis muaj kev txhim khu kev qha ua haujlwm. Thaum Nickel-based high-kub alloy alloy tiv thaiv kev tiv thaiv tau siv nyob rau hauv cov roj uas yog phosphides, lub siab-kub corrosion lub sijhawm yog li 20 txog 30 teev. Hauv kev xyaum ntev ntev ntawm kev ntsuas kub ntawm ntau qhov kev ua tiav kub, thiab ua tiav cov kev tiv thaiv niaj hnub no ua cov raj hauv sab hauv, thiab ntsuas ntsuas qhov tseeb yog ua tiav. Qhov tshwj xeeb thermocouple tau ua tiav tau zoo thiab siv rau ntawm huab cua sov huab cua koov ntawm cov neeg siv kub heev rau ntau dua ib nrab ib xyoos.

Cov txheej txheem txheej txheem ntawm armored thermocouple

Nws yog ua los ntawm tus neeg coj ua, kev thaiv cov rwb thaiv tsev siab hlau nplaum magnesium oxide, thiab sab nraud dej 1Cr18TI Stainless hlau tiv thaiv raj, uas yog kos rau hauv ib daig ntau zaus. Lub tsho tiv thaiv thermocouple thermocouple, lub davhlau ya nyob twg yog cov qauv thermocouple ua cov qauv yooj yim, thiab yog nruab nrog ntau cov kev teeb tsa thiab kho cov khoom siv.

Thermocouple ntsuas kub ntsuas

Nws yog raws ntawm cov nyhuv thermoelectric nyhuv. Thaum ob tus neeg sib txawv lossis cov semiconductors txuas rau hauv lub voj kaw, thaum lub qhov kub ntawm ob lub junctionsts yog txawv, ib lub peev xwm thermoeltric yuav tsim tawm hauv lub voj. Qhov tshwm sim no hu ua Thermoelectric effect, tseem hu ua cov nyhuv pom.

Raws li ib tug kub ntsuas sensor, muaj cov khoom siv thermocoenter feem ntau yog siv cov khoom siv kub thiab cov roj ntsha thiab cov roj ntsha thiab cov roj ntsha hauv thaj chaw ntawm {{} degree hauv ntau cov txheej txheem ntau lawm.

Cov cuab yeej thermoco tau muaj ntau yam zoo xws li bendabages, kev kub siab tiv taus, lub sijhawm muaj kev kub ceev thiab kav ntev. Zoo li muaj kev lag luam thermoco, lawv tau siv raws li cov ntsuas ntsuas rau ntsuas kub thiab feem ntau yog siv cov twj paj nruag tso tawm, kaw cov cuab yeej siv hluav taws xob.

Kev ntsuas hluav taws xob ntawm cov thermored thermoco

Kev ntsuas hluav taws xob thiab cov cuab yeej rau cov hlau yaj suab nrawm tawg ua thermocouples.

Cov cuab yeej siv feem ntau muaj cov cua sov lub tiaj tus cua sov uas tuaj yeem haum ob leeg plaub ntawm cov duab ntsuas kub thiab sib txuas nrog cov kev tswj hwm kub ua rau cov zaub mov tawm.

Txoj kev calibration:

Ua ntej, siv ob lub calibüro los nrhiav cov ntsiab lus hauv cov khub ntsuas hluav taws xob nrog cov khub ntsuas hluav taws xob sib xyaw ua ke

Nta:

a. Cov cuab yeej muaj cov cua sov kauj, ib nkawm calibration armored thermocouples thiab ntsuas kub tswj zaub cov zis tawm.

b. Cov qauv pov thawj yog txhawm rau ntxig rau ob lub calibrecine los ntawm ob qho kawg ntawm cov cua sov chev kom ua rau kub thermored thermocouples chwv. Los ntawm kev hloov chaw ntawm calibration thermocouple hauv cov cua sov chev, lub peev xwm thermoelectric muaj peev xwm ntawm ob lub calibrine thermocoup yog tib yam. Hloov ib qho ntawm calibration thermocouples nrog ntsuas ntsuas cov txiaj ntsig nrawm nrawm nrawm ntawm qhov tseeb ntawm kev ntsuas nrawm nrawm nrawm nrawm.

Cov cuab yeej thermoco tau muab faib ua ob hom: insulated hom thiab lub plhaub hom.

Nws muaj ntau yam zoo xws li bendabtability, kev kub siab kuj, nrawm cua sov teb lub sijhawm thiab kav ntev. Nws yog tib yam li kev lag luam siv. Raws li lub sensor rau kev ntsuas kub, nws feem ntau yog siv nrog cov zaub digital, kaw cov ntsuas hluav taws xob thiab hluav taws xob. Nyob rau tib lub sijhawm, nws kuj tseem siv tau ua qhov kub siab lub caij. Nws tuaj yeem ncaj qha ntsuas qhov kub ntawm cov kua, chav thiab roj av nruab nrab thiab khoom saum npoo ntawm {{degree ~ 800 degree hauv ntau cov txheej txheem ntau lawm. Piv nrog, muaj kev ua rog thermocouples muaj qhov zoo ntawm kev ua phem, kev kub siab kuj, lub sijhawm luv luv ntawm lub sijhawm thiab kav ntev.
