1. Txog ntawmHom thermocouple:Hom thermocouple yuav tsum ua raws li cov teeb liab ntawm cov khoom ntsuas, thiab yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm kub; Thaum siv cov thermocouples, nws tseem yuav tsum tau siv cov xaim them nyiaj nrog tib lub ntsuas ntsuas kom txuas cov thermocouple rau cov khoom ntsuas.
2. Hais txog cov khoom ntawm cov khoom tiv thaivntawmcev:Lub raj tiv thaiv ntawm lub thermocouple feem ntau yog stainless hlau 1Cr18Ni9Ti, 1Cr18Ni12MoTi los yog SUS316L tuaj yeem siv rau hauv cov tshuaj corrosive huab cua, tantalum raj los yog Hastelloy tuaj yeem siv rau hauv cov kev daws teeb meem oxidizing muaj zog xws li sulfuric acid thiab nitrate acid, cua sov-resistant SUS10 SUS25. Feem ntau siv nyob rau hauv oxidizing cua ntawm ntau tshaj 900 degree, high-temperature alloy los yog high-alumina corundum porcelain raj feem ntau yog siv rau ntau tshaj 1000 degree, thiab tsuas corundum porcelain raj yuav siv tau rau ntau tshaj 1300 degree. Nyob rau hauv lub tshuab nqus tsev inert txo cua sov, tungsten-rhenium thermocouples nrog molybdenum thiab tantalum raws li kev tiv thaiv raj feem ntau xaiv. High alumina thiab corundum tiv thaiv raj yuav tsum tsis txhob siv nyob rau hauv ib tug dej vapor los yog txo cua.
3. Hais txog txoj kab uas hla thiab qhov ntev ntawm tus tiv thaivntawmcev:Qhov loj ntawm txoj kab uas hla ntawm lub raj tiv thaiv, lub thermal teb lub sij hawm ntev ntawm qhov ntsuas kub, qhov zoo ntawm cov khoom siv kho tshuab, thiab lub neej kev pab lub neej ntev ntawm qhov kub thiab txias. Rau cov qis dua 600 degree yam tsis muaj cov cuab yeej cuab tam yuav tsum tau, armored thermocouples nrog cov kab me me feem ntau xaiv. Kev sib sau cov thermocouples feem ntau yuav tsum muaj qhov ntev ntev rau hauv qhov ntsuas kub ntsuas nruab nrab kom ntsuas qhov ntsuas kub kom raug. Lub thermocouple ntsuas qhov kub ntawm qhov "point" qhov kub kawg nyob, thiab tus neeg siv yuav tsum txiav txim siab qhov ntev ntawm lub thermocouple raws li cov txheej txheem yuav tsum tau ua, thiab tag nrho qhov ntev ntawm lub thermocouple feem ntau yog +100mm lossis 150mm, los yog +250mm. Nco ntsoov tias qhov "insertion length" thiab "insertion length" ntawm lub thermocouple yog ob lub ntsiab lus sib txawv.
4. Txog ntawmtxheej txheem kev sib txuas:Rau siv nyob rau hauv unsealed ib puag ncig, assembled thermocouples feem ntau xaiv yam tsis muaj fixtures los yog nrog movable flanges, thaum armored thermocouples raug xaiv tsis fixtures los yog movable ferrule threads los yog movable ferrule flanges; Rau siv nyob rau hauv ib puag ncig kaw, threaded lossis flange mounting feem ntau xaiv. Cov pa xov rau kev sib dhos ntawm cov thermocouples yog M27x2, thiab cov pa flange yog Φ95 (tiv thaiv raj Φ16) lossis Φ105 (tiv thaiv raj Φ20). Thaum txoj kab uas hla ntawm armored thermocouple yog Φ2, 3 thiab 4, cov pa xov yog M12x1.5 thiab ferrule flange yog Φ55, thaum txoj kab uas hla yog Φ5, 6 thiab 8, cov pa xov yog M16x1.5 thiab ferrule flange yog Φ65, thiab cov pa xov ntawm armored thermocouple txuas yeeb nkab yog M20x1.5.
5. Txog ntawmkab txuas:Kev xaiv cov khoom siv hluav taws xob txuas yuav tsum yog rau lub hom phiaj ntawm kev yooj yim thiab kev ntseeg tau. Thaum lub armored thermocouple tsis muaj lub thawv sib txuas, muaj cov khoom siv hluav taws xob cov khoom siv hluav taws xob, cov kaus mom tiv thaiv dav dav, lub caij nplooj ntoos hlav tiv thaiv lub kaus mom, thiab cov hlau hose tiv thaiv lub kaus mom; Thaum sib sau ua ke ib lub thermocouple tsis muaj lub thawv sib txuas, muaj lub davhlau ya nyob twg thaiv thiab ib qho yooj yim binding ncej. Thaum nws yog nrog junction box, nws yog tsuas yog siv rau plua plav, waterproof thiab tawg-pov thawj, nrog rau waterproof hlws ris lub thawv, splash-proof hlws ris lub thawv, tshuab-pov thawj hlws ris lub thawv, dII.BT4 flameproof hlws ris lub thawv, dII.CT5 flameproof hlws ris box , tawg-pov thawj hlws ris lub thawv nrog rau ntawm qhov chaw tso saib, multi-point junction box, thiab splash-proof hlws ris lub thawv tuaj yeem hloov tau los ntawm lub thawv dej sib txuas.
6. Hais txog daim ntawv ntsuas kawg:Cov thermocouple sib sau ua ke feem ntau yog hom insulated, tab sis kuj tseem muaj lub plhaub hom (piv txwv li, ib qho me me inert thermocouple), thiab cov tub ntxhais thermocouple kuj tuaj yeem siv ncaj qha yam tsis muaj lub raj tiv thaiv; Muaj ob hom armored thermocouples: insulated thiab grounded, feem ntau insulated, thiab thermal teb lub sij hawm ntawm grounding thermocouples sai dua, tab sis lawv muaj kev cuam tshuam rau electromagnetic cuam tshuam, thiab lub plhaub yuav tsum muaj kev ntseeg siab hauv av.
