Dab tsi yog qhov txawv ntawm armocouple thiab hluav taws xob thermocouple?
Tso lus
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. Dab tsi yog qhov sib txawv ntawm thermored thermocouples thiab hluav taws xob thermocouples?
Hluav taws xob thermocoal yog qhov kub siab xav tau xov hlau thiab sensors ntawm cov tshuab ntsuas kub. Lawv yog preses rau kev ntsuas kub.
Qhov tseem ceeb ntawm hluav taws xob thermocoecles yog los tsim lub peev xwm thermoelectric thaum lub ntsuas kub ntawm ob qho kawg ntawm thermocouple yog txawv (qhov sib txawv).
Nws lub hom phiaj tseem ceeb
yog los xyuas qhov kub thiab txias los ntawm kev siv cov kev sib raug zoo ntawm thermoelectric muaj peev xwm thiab kub sib txawv; Thib ob, nws yog siv rau kev kub kub sib txawv.
Nws yog tsuas yog siv rau kev ntsuas kub. Raws li cov kub sib txawv, nws tau muab faib ua b, R, S, K, n, e, thiab t hom. Qhov qis tshaj kub yog -270 degree thiab kub siab yog 1800 degree.
Cov txheej txheem txheej txheem ntawm armored thermocouple
Nws yog ua los ntawm tus neeg coj ua, rwb thaiv tsev siab mages magnesium oxide, thiab sab nraud tsho 1cr18ni9ti stainless hlau tiv thaiv ntau zaus. Cov khoom siv hluav taws xob thermocouple feem ntau muaj lub thawv hlws ris, davhlau ya nyob twg yog cov qauv yooj yim, thiab yog nruab nrog ntau cov kev teeb tsa thiab kho cov khoom siv.
Armored Thermocouple tau muab faib ua cov hom insulated thiab lub plhaub hom.
Nws muaj ntau yam zoo xws li kev puas yog khoov, muaj kev kub siab tiv taus, kev teb nrawm cua sov thiab kav ntev. Nws yog siv los ua qhov kub thiab txias xws li kev siv hluav taws xob, thiab siv nrog cov xov hlau kev lag luam thiab cov khoom siv hluav taws xob metres, sau cov ntsuas thiab tshuab hluav taws xob. Nyob rau tib lub sijhawm, nws kuj tseem siv tau ua qhov kub siab lub caij. Nws tuaj yeem ntsuas qhov ntsuas kub ntawm cov dej, chav thiab roj av nruab nrab thiab cov khoom sib txawv hauv 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.
Thermocouple ntsuas kub ntsuas
yog ua raws li 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 siv rau kev ua paug thermoco ntawm cov hlau melts
Cov cuab yeej siv yog suav nrog ib lub tiaj tus cua sov coil uas tuaj yeem haum rau cov plaub fab ntawm ob qho kev ntsuas ntawm ob qho kev ntsuas, thiab ntsuas qhov ntsuas kub ntsuas cov zaub rau cov khoom tawm.
Cov Qauv Kev Tshawb Xyuas:
Ua ntej, siv ob lub calibration thermocouples kom nrhiav tau cov ntsiab lus hauv cov khub therm uas ua rau ob qho kev ntsuas hluav taws xob muaj peev xwm siv cov khub ntsuas nrog ntsuas sib ntsuas. Thaum lwm cov xwm txheej tsis hloov pauv, tom qab kev nyeem ntawm covir hlau ntsuas cabilizes, nws tuaj yeem piv nrog cov khub ntsuas hluav taws xob tau paub seb puas muaj nqi ntawm tus nqi ntsuas yog qhov tseeb.
Nta:
a. Cov cuab yeej yog muaj xws ntawm ib lub tiaj tus cua sov chev, ib nkawm calibration armored thermoco, thiab ntsuas kub tswj zaub cov zis tawm.
b. Cov qauv pov thawj yog kom xub tso thermocouples los ntawm ob qho kawg ntawm cov cua sov kauj rau ib leeg kom cov kub kub xaus ntawm lub tshuab cua sov tau sib cuag. Los ntawm kev hloov chaw ntawm calibration thermocouples nyob rau hauv cov cua sov chev, lub thermoelectric muaj peev xwm ntawm ob calibrine thermocoup yog ua tib yam. Hloov ib qho ntawm cov calibration thermocouples nrog cov ceev ceev thermocoupric muaj peev xwm paub lub zog calibrecero kom paub lub zog ceev thermocouple mus kuaj.
