Yuav ua li cas nrog cov thermocouple hlawv los ntawm qhov cub hluav taws

1. Kev txhais thiab kev ua haujlwm ntawm cov thermocouples
Thermocouples yog ib qho khoom siv ntsuas kub uas siv los ntawm ob lub xov hlau sib txawv. Ob txoj hlua hlau yog qhov chaw welded ua ke los tsim ib lub voj voog. Thaum muaj qhov kub sib txawv ntawm ob qhov kawg ntawm lub thermocouple, ib qho hluav taws xob yuav raug tsim tawm. Qhov hluav taws xob no hu ua thermoelectric peev xwm thiab tuaj yeem siv los ntsuas qhov kub thiab txias.

2. Qhov cuam tshuam ntawm qhov cub hluav taws kub ntawm cov thermocouples
Qhov kub ntawm qhov cub hluav taws kub tuaj yeem ua rau muaj kev cuam tshuam loj rau lub thermocouple. Kev kub siab dua tuaj yeem ua rau thermal expansion ntawm cov hlau xaim, uas yuav ua rau cov thermocouples poob kev sib cuag ruaj khov thiab cuam tshuam qhov tseeb ntawm qhov ntsuas kub. Tsis tas li ntawd, qhov kub thiab txias kuj tseem yuav ua rau muaj teeb meem xws li oxidation thiab corrosion ntawm cov khoom siv thermocouple, ntxiv kom txo tau qhov kev ua haujlwm ntawm cov thermocouple.

3. Kev daws rau thermocouple kub hauv qhov cub hluav taws kub
Thaum ntsib cov thermocouple hlawv hauv lub cub tawg, peb tuaj yeem siv qee qhov kev ntsuas los daws qhov teeb meem.

4. Xaiv cov thermocouples ua los ntawm cov khoom siv kub-resistant
Qhov kub thiab txias ib puag ncig hauv qhov cub hluav taws tuaj yeem ua rau muaj kev puas tsuaj loj rau cov thermocouples, yog li thaum xaiv cov thermocouples, nws yog ib qho tsim nyog yuav tau xav txog kev siv cov khoom siv kub-resistant. Cov ntaub ntawv kub-resistant ntau yam xws li platinum rhodium alloys, tungsten rhenium alloys, thiab lwm yam. Cov ntaub ntawv no muaj cov ntsiab lus siab melting thiab oxidation tsis kam, thiab tuaj yeem ua haujlwm ib txwm nyob rau hauv qhov kub thiab txias.

5. Nruab lub tes tsho tiv thaiv
Txhawm rau tiv thaiv cov thermocouples los ntawm kev kub nyhiab ntawm qhov cub hluav taws, lub tes tsho tiv thaiv tuaj yeem ntsia tau ib ncig ntawm qhov chaw ntawm lub thermocouple. Lub tes tsho tiv thaiv feem ntau yog ua los ntawm cov khoom siv kub-resistant ceramic lossis hlau. Qhov no tuaj yeem txo cov cua sov hloov ntawm lub qhov cub hluav taws mus rau lub thermocouple thiab txhim kho nws lub neej kev pab.

6. tsis tu ncua kev sim thiab kev saib xyuas
Txhawm rau kom ntseeg tau qhov tseeb thiab ruaj khov ntawm cov thermocouples, nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas thiab tswj lawv. Cov cuab yeej ntsuas kub ntsuas kub tshaj lij tuaj yeem siv los ntsuas cov thermocouples kom ntseeg tau qhov tseeb ntawm kev ntsuas ntsuas. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tau ntxuav cov thermocouples tsis tu ncua thiab hloov cov khoom hnav lossis puas tsuaj rau lub sijhawm.

Kev kub hnyiab ntawm cov thermocouples nyob rau hauv lub cub tawg yog ib qho teeb meem tshwm sim, tab sis nws tuaj yeem daws tau los ntawm kev xaiv cov khoom siv kub-resistant, txhim kho lub tes tsho tiv thaiv, thiab ua kev soj ntsuam thiab tu. Cov kev ntsuas no tuaj yeem ua kom lub cev ua haujlwm ntawm cov thermocouples nyob rau hauv qhov chaw kub kub, txhim kho qhov tseeb thiab kev ntseeg siab ntawm kev ntsuas kub.
