Vim li cas hnav-tiv thermocouples tseem ceeb hauv kev tsim khoom?

Qhov tseeb soj ntsuam yog tus ncej ntawm cov tso zis zoo, cov txheej txheem ua haujlwm, thiab cov cuab yeej siv sia nyob rau hauv cov zog thiab feem ntau xav tau tiag tiag ntawm kev tsim khoom. Tawm los ua cov twj tseem ceeb, hnav-cov thermocoive yog qhov tseem ceeb rau kev tswj hwm qhov kev ua haujlwm ntawm kev ua haujlwm. Paub vim li cas lawv tseem ceeb heev pab ib qho kom txaus siab rau lawv qhov tseem ceeb hauv cov haujlwm tseem ceeb no.
Hnav-resistant thermocouples yog qhov tsim nyog nyob rau hauv ntau lawm vim yog muaj peev xwm ua kom dhau kev puas siv tshuab puas yog siv tau. Ntau cov chaw tsim khoom muaj xws li cov lus tsa suab txuas ntxiv, kev co, thiab kov nrog cov khoom siv abasive. Hauv kev ua haujlwm hlau ua haujlwm, thaum muaj cov cuab yeej siv, lossis nias cov khoom siv abrips Feem ntau ua los ntawm rauv sab nraud sheaths tsim los ntawm cov ntaub ntawv zoo li cov alloys muaj zog lossis ceramics, hnav-tiv taus thermocots tuaj yeem tiv thaiv cov chaw uas xav tau no. Lawv tau lees tias cov thermocouple nyob ntawm kev ua haujlwm thiab ua kom muaj kev nyeem ntawv kub kub los ntawm kev tawm tsam cov tshuab puas zoo li chipping thiab khawb. Tswj qhov zoo ntawm cov khoom lag luam tsim tawm nyob ntawm qhov kev pab cuam no yog tias qhov kev hloov pauv kub me me yuav ua rau kub tsis sib xws.
Lwm qhov tseem ceeb yog lawv txoj kev ua siab ntev rau cov kub thiab muaj ntau cov tswv yim ntau lawm. Kev kho cua sov, casting, thiab vuam ntawm lwm cov txheej txheem nthuav tawm cov khoom siv rau cov khoom kub siab heev. Tsim los khaws cov kev ncaj ncees thiab qhov tseeb txawm tias cov khoom siv cua sov kub uas tuaj yeem tsim cov phiaj xwm cua sov kom muab cov cim hluav taws xob nrog rau qhov ntsuas kub. Ib qho kev hnav-resistant thermocouple tuaj yeem soj ntsuam qhov kub ntawm cov hlau nyob rau hauv ib qho kub, yog li ua tau zoo dua 1000 degree, yog li ua kom pom tseeb meej thiab tsis txhob ua pov cov flaws.
Lwm qhov tseem ceeb ua kom zoo uas ua rau hnav cov thermocouples tseem ceeb hauv kev tsim tau yog corrosion tsis kam. Ntau cov txheej txheem hu rau cov kuab tshuaj, tshuaj lom neeg, lossis caustic tebchaw. Piv txwv li, muaj kev phom sij rau cov acids, alkalis, thiab lwm yam tshuaj kho hauv tsheb tsim khoom lag luam xws li electroplating lossis pleev xim. Cov ntaub ntawv siv nyob rau hauv cov khoom siv-resistant thermocoup yog txhais tau los tiv thaiv corrosion, yog li ntawd yuav thaiv cov sab hauv los ntawm kev ua mob. Ua yeeb yam ua ib qho kev thaiv, kev tiv thaiv sheative ua rau cov tshuaj uas xeb kom deb ntawm cov khoom noj ntshiabmocouple. Qhov no tau lees tias qhov kev vam meej ntawm qhov kub nyeem tag nrho cov sij hawm zoo li lub neej ntawm thermocouple.
Qhov kev ua tau zoo ntawm kev ua haujlwm nyob ntawm ntau ntawm kev ua siab ntev ntawm kev hnav-tiv thaiv thermoco. Cov kev hloov pauv tau yog qhov tsawg dua uas tsim nyog raws li lawv tsis tshua muaj txiaj ntsig kom swb los ntawm kev hnav, corrosion, lossis kub siab. Ib qho nqes sij hawm tshwm sim los ntawm thermocouple tsis ua haujlwm yuav ua rau muaj kev poob zoo hauv txoj kab kev ua lag luam txuas ntxiv. Hnav-resistant thermocouples txo qhov kev phom sij no kom cov txheej txheem ntau lawm yuav khiav tsis tau. Lawv lub neej ntev kev pabcuam tseem pab cawm cov nuj nqis los ntawm kev soj ntsuam ntau zaus, lossis hloov pauv tsis tau muaj.
Hnav cov thermocoive tseem pab cov tuam txhab kom tswj cov txheej txheem zoo dua. Yam tseeb thiab kub zoo nkauj nyeem cov neeg ua haujlwm los hloov cov txheej txheem ntau lawm, yog li cov khoom cua sov, lub sijhawm txias, thiab ua tiav qhov ntev. Qhov kev tswj hwm no ntawm kev tswj no yuav pab txo qis khib nyiab, nce kev tsim khoom lag luam, thiab txhim kho cov khoom lag luam zoo.
Vim hais tias ntawm lawv lub sijhawm ntev thiab pab tswj cov txheej txheem, hnav-cuam tshuam thermocouples yog qhov kev puas tsuaj loj heev, muaj kev kub ntxhov siab, thiab xeb. Lawv yog yog li cov khoom tsim nyog ntawm cov kev ua ub ua no raws li lawv cov tswv yim uas tau lees paub tias cov kev paub ntau ntxiv tau ua tiav nrog qhov tseeb, kev cia siab, thiab ua haujlwm.
