Dab tsi yog cov vuam txoj kev siv rau thermocouple kub electrodes

Txhua tus neeg hauv ntiaj teb no paub tias ib lub thermocouple yog qhov ntsuas kub uas muaj ob tus neeg coj ua thermoelectric, ua ke. Nws tseem yog cov siv tau siv ntau tshaj plaws hauv cov twj kub feem ntau. Yog li, nyob rau hauv kev tsim khoom lag luam ntawm thermocouples, li cas yog vuam ntawm Thermoelectric cov hluav taws xob tsis nres?

1. roj av vuam txoj kev

Txoj kev no yog yooj yim rau kev tswj hwm thiab siv dav. Thaum siv roj vuam, sab saum toj ntawm cov thickoelectum electrode thiab ib nrab quartz xuab zeb sib xyaw yuav tsum muab tso rau hauv cov pa roj av lossis cov nplaim taws hydrogen oxygen. Tom qab tau yaj mus rau hauv ib lub ntsej muag sib xyaw, nws yuav tsum tau tshem tawm sai sai thiab muab tso rau hauv dej kub sai sai ntawm qhov chaw nyob ntawm qhov chaw nyob ntawm qhov chaw vuam. Txoj kev vuam vuam no yog cov tswv yim rau kev tsim cov roj qis hlau thermocoples.

2. Arc Vuam Txoj Kev

Arc vuam txoj kev tau muab faib ua kev sib cais ncaj qha rau arc vuam thiab sib pauv arc vuam.

DC arc vuam yog cov txheej txheem ntawm kev sib txuas ib tus ncej ntawm lub zog ntawm lub zog thiab cov pa roj carbon monoxide (spectral) rau cov ncej tsis zoo ntawm lub zog. Cov pa roj carbon thiab sab saum toj kawg ntawm thermoelectric electrode yog siv los pib lub arc, thiab cov pas nrig carbon tau sai sai tom qab ntsuas qhov kawg melts mus rau hauv cov duab kheej. Qhov vuam vuam no yooj yim, yooj yim rau kev khiav lag luam, thiab ntsuas kev ntsuas kom yooj yim tsis yooj yim, ua rau nws haum rau vuam hlau hlau thermocots.

Txauv arc vuam yog siv rau vuam tsawg-nqi hlau thermocouples. Ua ntej vuam, cov oxide nyob rau hauv {{mi mm tshooj ntawm ob electrodes yuav tsum tau ua kom huv si yuav tsum tau ua kom huv si, thiab tom qab ntawd ob qho yuav tsum tau ua kom huv si, thiab tom qab ntawd ob qho yuav tsum tau ua kom huv si, thiab tom qab ntawd ob qho tib si yuav tsum tau ua kom tiav thiab sib ntswg ua rau lub ntsej muag kib. Thaum vuam, chip sab saum toj kawg ntawm lub thermoelectric electrode hauv shader flux thiab yaj nws hauv arc nplaim taws rau {2}} vib nas this. Tom qab nws tsim pob duab, tshem tawm sai sai thiab nkag siab qhov seem ntawm cov sib koom sib ke. Cov qauv no muaj cov cuab yeej siv yooj yim thiab kev lag luam yooj yim, tab sis qhov thermocouple vuam cov ntsiab lus thiab cov hluav taws xob ib sab muaj zog rau carburization thiab kev paug.

3. Salwater vuam txoj kev

Txoj kev vuam vuam no yog qhov ua tau rau kev siv thermocouples nrog lub cheeb ntawm {}}. 03mm {2}}. 3 hli. Sau cov beaker nrog sodium tshuaj chloride tov, tso platinum xaim ua ib elctrode nyob rau hauv cov kua aqueous, thiab siv cov kub electrode raws li lwm cov hluav taws xob. Thaum vuam, sib koom me ntsis rau sab saum toj ntawm thermocouple nrog txoj kev daws, tig rau lub zog, thiab nrawm nruam lub zog tom qab arc pib.

4. Argon arc vuam txoj kev

Lub Argon arc vuam installation muaj tsib lub dog teb cov khoom siv, kev siv phom loj, pob tw, taub qab vuam lub zog mov, thiab kho kom zoo. Thaum vuam, cerium tungsten hlau txuas los ntawm vuam rab phom tas li yuav tsum tau siv los ua kom khov kho mus rau qhov fixture raws li qhov zoo. Thaum cov txheej txheem nruab nrab ntawm sab qaum teb thiab sab qab teb sab qab teb dhau mus los ntawm cov hluav taws xob siab thiab ntau hluav taws xob, qhov chaw tiv thaiv ntawm lub arc yuav cuam tshuam. Lub tshuab hluav taws xob sib tshooj yog siv los tswj kev siv ARC, thiab hauv qab kev txij nkawm ntawm kev sib cav, ARC paug yuav tshwm sim ntawm cerium tungsten thiab welded thermocouple. Lub qhov kub qis tsim los ntawm arc yuav yaj kawg lub ntsej muag kawg ntawm cov xaim hluav taws xob thermocouple. Txhawm rau kom yooj yim ntawm cov kev sib dhos ntawm thermocouples thiab electrodes, ua fixture thiab vuam phom tuaj yeem txav mus rau qhov chaw. Lub vuam rab phom yog nruab nrog cerium tungsten hluav taws xob nrog diameters ntawm 1mm thiab 1.5mm rau Thermocouple vuam cov ntawv thov.

5. Carbon Hmoov Vuam Txoj Kev

Hom no yog ua tau rau kev siv vuam tsawg-nqi hlau thermocots. Lub installation ntawm carbon hmoov vuam yog zoo ib yam li arc vuam, tsuas yog ib tus ncej ntawm cov roj carbon, thiab lwm tus ncej sib txuas nrog cov thermocouple tau welded. Thaum vuam, tshem cov thermoelectric electrode los ntawm graphite hmoov thiab tos rau ob peb feeb kom tiav lub vuam. Txoj kev vuam vuam no yooj yim dua li arc vuam, tab sis nws yog nquag ua rau brittle bacitture ntawm cov kub electrode.
