Kev xaiv ntawm muaj thermocouple them nyuj qauv

Ua ntej tshaj plaws, qhov kub ntawm thermocouple yog 1200 degrees. Puas yog qhov kub tshaj plaws uas cov thermocouple tuaj yeem tiv taus lossis kub uas ua haujlwm kawg ntawm lub thermocouple yuav ntsuas? Txhawm rau ua ib thermocouple, ob txoj xov hlau ntawm cov khoom sib txawv yog xav tau. Ib kawg yog welded thiab hu ua haujlwm kawg, thiab lwm qhov kawg yog hu ua qhov siv kawg. Qhov kub yog ntsuas los ntawm lub thermoelectric peev xwm tsim los ntawm qhov sib txawv ntawm qhov sib txawv ntawm kev ua haujlwm kawg thiab qhov siv kawg. Txawm li cas los xij, tsuas yog ib hom xaim xaim yog muab rau cov lus nug. Cia peb txheeb xyuas nws raws li cov npib tsib xee-chromium-lickel yog siv rau qhov kub-aluminium (lossis raug tso cai siv hauv qhov kub ntawm 1200 degrees hauv lub sijhawm luv luv. Cov ntsiab lus hauv qab no yuav tsum tau sau tseg rau kev xaiv ntawm cov xaim hluav taws xob: 1. Cov neeg siv hluav taws xob tsawg dua nrog cov npib tsib xee-chromium-Alickel-Aluminium them xaim). 2. Tus ncej zoo ntawm cov xaim hluav taws xob txuas nrog tus ncej zoo ntawm thermocouple, thiab tus ncej tsis zoo yog txuas nrog tus ncej tsis zoo. Qhov kev sib txuas yuav tsum tsis yog qhov txhaum. 3. Qhov kub ntawm ob lub ntsiab lus sib txuas ntawm cov xaim hluav taws xob thiab cov thermocouple yuav tsum zoo ib yam thiab yuav tsum tsis pub tshaj 100 degrees. 4. Tom qab cov thermocouple txuas nrog rau cov xaim xaim, qhov ntsuas qhov kawg yuav tsum raug kho.
Thermocouple them hlau muaj cov xaim hluav taws xob thiab rwb thaiv tsev txheej;
Cov hlau them yuav tsum tau muab faib ua txuas ntxiv thiab them nyiaj raws li cov ntaub ntawv sib txawv ntawm cov qauv xaim tseem sib txawv. Cov nqi them txuas ntxiv hlau suav nrog NX (Nickel-Chromium-Npib-Npib-Npib-Npib-Nickel 45), JX (TXWV (Tooj-tooj-Nickel 45), thiab tooj-tooj liab-tsibck (tooj liab-tsibcke 40), NC (hlau Tooj), thiab lwm yam.
Rag thaiv txheej thiab cov khoom siv rwb thaiv tsev ntawm cov ntawv them nyiaj xaim xaim hluav taws xob suav nrog polyvinyl chloride, polytetrafluoroethylene, iav fiber ntau, quartz xov thiab ceramic fiber, thiab lwm yam; Cov hlau thaiv cov txheej suav nrog stainless hlau mesh, thiab lwm yam.
Thermocouple Them Hlau txuas nrog saib cov twj paj nruag, uas tau siv hluav taws xob, ntsuas hluav taws xob, kev tiv thaiv thiab kev tshawb fawb, lwm cov chaw.
Tus txheej txheem yooj yim ntawm thermocouple kub ntsuas
Ob tug cwj pwm ntawm cov khoom sib txawv ua ib lub voj kaw. Thaum muaj qhov ntsuas kub ntawm ob qho kawg, tam sim no yuav dhau los ntawm lub voj. Nyob rau lub sijhawm no, muaj lub zog hluav taws xob ntawm ob xaus - thermoelectric lub zog hluav taws xob lub zog, uas yog qhov thiaj li hu ua cov nyhuv pom.
Ob homogeneous kev coj ntawm cov khoom sib txawv yog thermocouples. Qhov kawg nrog qhov kub siab dua yog qhov ua haujlwm kawg, thiab qhov kawg nrog qhov kub qis dua yog qhov kawg. Qhov kawg xaus feem ntau yog nyob rau ntawm qhov kub tsis tu ncua.
Raws li txoj kev sib raug zoo ntawm thermoelectric lub zog quab yuam thiab kub, ib lub ntsuas phoo thermocouple tau ua; Cov nplai yog tau thaum qhov kub ntawm qhov kawg ntawm qhov kawg yog 0 degree, thiab sib txawv thermocouces muaj cov nplai sib txawv.
Thaum ib tus thib peb cov khoom siv hlau txuas nrog lub voj voos hluav taws xob thooper, ntev npaum li qhov kub ntawm cov khoom siv yog tib yam, nws yuav tsis cuam tshuam los ntawm kev sib txuas ntawm tus thib peb hlau rau lub voj.
Yog li ntawd, thaum ntsuas ntsuas ntsuas kub ntawm thermocouple, ntsuas ntsuas yuav tau txuas. Tom qab ntsuas ntsuas cov thermoelectric lub zog hluav taws xob, qhov ntsuas kub ntawm qhov ntsuas ntsuas ntsuas tau tuaj yeem paub.
