Cov nyhuv ntawm cov cua hauv thermocouple siv

1) Xaiv oxidation

Rau Ni-Cr Alloy Muaj Fe, Yog tias Oxygen Partial siab yog qis dua li ntawm lub tshuab hluav taws xob, uas yog qhov feem ntau hu ua "ntsuab corrosion" {}}} Thaum qhov ntsuas kub nyob hauv qhov ntau ntawm 800℃{}}℃thiab lub kaw lus tsawg dua los ua kev txwv tsis pub dhau ntawm K-hom thermocouples nyob rau hauv kev kho cua sov Kev lag luam .

Yog tias cov roj siv yog ntshiab thiab tsis muaj oxygen nyob rau hauv lub qhov dej oxiding ntawm blococouple pan, yog tias muaj nyob rau hauv qhov chaw tsis yog huab cua, thaum siv cov roj oxiding, thaum siv cov roj oxiding siv . tib lub sijhawm, nws yuav tsum zam kom ntau li ntau tau nyob rau hauv cov pa roj carbon monoxial} Thaum muaj cov pa hluav taws xob tsawg heev), vim tias muaj huab cua tsis zoo yog tsim, thiab seem uas muaj cov pa loj tseem tuaj yeem muab cov kev mob rau cov xaiv oxidation ntawm cr.

(2) Kev Counterme rau kev xaiv oxidation

Txhawm rau tiv thaiv lossis qeeb qeeb ntawm kev ua kom qeeb ntawm K-hom ThermoOns vim muaj kev xaiv cov khoom siv oxidation, piv txwv li kev txheeb xyuas cov qauv ntawm cov qauv ntawm lub thermocouple:

① Xaiv cov hlau uas muaj zog muaj zog dua li tus pas dej tiv thaiv kab mob oxidation {}}}

Ua lub cev lub cev ruaj khov thermocouple. Cov khoom lag luam uas siv los ntawm ntau lub tuam txhab kev sib cav xws li Wazhou pawg, FOMBILE, thiab kev lag luam tawm thib ob, ipsen muaj Rauv, Shenyang Hnyav Kev Lag Luam, Shenyang iav, Qianjiang Maus, thiab lwm yam kev pabcuam lub neej yog ntau dua 12 lub hlis thiab cov neeg siv tau zoo siab heev [4] {}

(3) Ces cawv ntawm kev thov cua

Qhov kev ruaj ntseg ntawm thermocouts sib txawv nrog cov ntawv thov kub thiab cov ntsiab lus ntau dua los kuj tau txiav txim siab sib txawv raws li cov haujlwm thov:

① Cov ntsuas kub uas yog thiab ntau tshaj qhov ntsuas kub

② Daim ntawv thov huab xws li oxidation rov qab

③ Los tiv thaiv kev ua haujlwm vibration

Rau kev tshem tawm thermocouples, tus kab mob yog qhov tsim nyog, nws yog qhov tsim nyog yog li ntawd, nws yog qhov tsim nyog yog li cas los ua cov kev tiv thaiv lub cev Tubes . Nyob rau hauv H2 Cheeb Tsam Muaj Kev Siv Ua Ntej {} Txawm li cas los xij, qhov tsim nyog thov los ntawm cov khoom siv oxiding {} hauv cov econdizing huab cua saum 1300 degree, ib qho platinum-rhodium thermocouple yuav tsum tau xaiv. hauv qab rov qab thiab precision, a radsten-rhaulaus thermocouple yog zoo dua.

K-hom thermocouples yog qhov haum rau kev ua haujlwm hauv huab cua, tab sis thaum siv hauv H2, uas tau siv rau hauv lub sijhawm luv luv, tab sis thaum siv sijhawm ntev, thaum ua kom nrawm dua, cov xaim yuav loj tuaj thiab tawg; nyob rau hauv ib qho chaw so kom zoo xws li co lossis pa roj av, nws qhov kev ntshai yuav tau nrawm dua thiab tshaj qhov tsis kam rau.

Rau cov thermored thermocouples, cov atomic voj voog ntawm hydrogen yog qhov yooj yim heev, uas yuav ua rau muaj kev cuam tshuam nrawm dua rau hauv lub thermoelectric muaj peev xwm txo tus nqi .

(4) cawv ntawm rwb thaiv tsev tsis kam

Thermococes siv rwb thaiv tsev cov ntaub ntawv {}}}} Tam sim no yuav txo qis lossis tsis ruaj khov los yog ua rau muaj kev cuam tshuam rau kev sib txawv los yog ua rau lub tshuab raj mismanaged .
