Yuav ua li cas siv siv cov xov tooj thermocouple?

Kev siv cov nyiaj thermocouple ntsiav tshuaj kom raug?

Tib neeg tuaj yeem pom qhov kub thiab txias hloov, tab sis yog qhov ntsuas kub hloov ntau dhau, nws txaus ntshai heev rau cov neeg tuaj ntsib nws. Yog li ntawd, nws yog ib qho tseem ceeb heev yog tias cov khoom tuaj yeem hloov cov neeg thiab muaj qhov ntsuas kub ntau yam. Thermouvles ua tiav txoj haujlwm no los ntawm kev hu ncaj qha rau ib puag ncig ua haujlwm thiab xa cov kev xav kub nyob hauv lub sijhawm tiag tiag.

Dab tsi yog thermocouple? Qhov ntsuas kub tau ua tiav kub npaum li cas?

Nws muaj ob qho sib txawv ntawm cov hlau welded ua ke los ua qhov ntsuas hluav taws xob. Ntev npaum li qhov kub ntawm ob lub vuam cov ntsiab lus sib txawv, hluav taws xob muaj zog yog tsim nyob rau hauv Circuit Court, uas yog hu ua Thermoelectric muaj peev xwm.

Kom paub qhov tseeb kub ntawm lub chaw ua haujlwm, tso ib qho ntawm cov pob qij txha welded rau hauv ib puag ncig ua haujlwm thiab ua rau lwm cov sib koom tes mus rau chav tsev. Los ntawm kev muaj pes tsawg leeg thiab cov ntsiab cai ntawm thermocouples, nws tau paub tias tiam ntawm thermoelectric peev xwm yog cuam tshuam nrog qhov sib txawv ntawm ob lub junctions. Yog li ntawd, tsuas yog thaum lub ambient kub yog xoom ntawm chav tsev kub tuaj yeem ntsuas kub hauv qhov chaw ua haujlwm tiag tiag. Txhawm rau daws cov kev ntsuas ntsuas los ntawm kev ntsuas kub ib puag ncig, thov cov txheej txheem xaim hluav taws xob raws li cov chaw nyob sab nraud yog qhov yooj yim tshaj plaws thiab txoj hauv kev zoo.

Kev Them Nyiaj Thermocouple Log

Nws yuav tsum raug sau tseg tias cov xaim hluav taws xob tsis yog qhov tseem ceeb siv rau kev them nyiaj, tab sis theej kom ntev) muab tso rau hauv ib puag ncig mus rau cov cuab yeej thib ob. Yog li ntawd, txoj haujlwm tseeb ntawm cov xaim hluav taws xob yog kom txuas ntxiv qhov txias txias rau ib txoj haujlwm tshwj xeeb rau kev ua.

Vim muaj ntau hom thermocouple, txhua tus nrog cov xaim nyiaj xaim, lawv yuav tsum tsis txhob siv cov ntaub ntawv, txwv tsis pub cov zaub yuam kev yuav ntau dua. Thaum xaiv, them sai sai rau cov kev sib piv kom raug.

Raws li lub hauv paus ntawm thermocouple, nws lub teeb liab yog thermoelectric peev xwm, uas belongs rau analog millivolt teeb liab thiab yog DC. Yog li no, cov xov thermocouple tau muab faib ua cov qauv zoo thiab tsis zoo, thiab nws cov hlau roj av kuj tau muab faib ua qhov zoo thiab tsis zoo thaum siv.

Thermocouple Them Hlau

Raws li cov saum toj no, cov khoom them nyiaj Thermocouple tau raug xaiv nrog tus qauv raug, kev cai polarity, thiab nws tsis tuaj yeem sib xyaw nrog cov xov hlau zoo tib yam.

Yuav siv cov xov tooj hluav taws xob li cas?

Thawj kauj ruam yog xaiv cov xov tooj ntawm cov nyiaj them rau cov thermocouple siv, xws li siv K-hom thermocouple roj teeb rau lub k-hom thermocouple.

Kauj ruam 2 xaim: Txuas cov seem uas muaj peev xwm kaw tau rau lub peev xwm thermocouple kom paub txog kev nyab xeeb rau cov cuab yeej thib ob. Zam kev cov khoom siv hluav taws xob xws li cov kiv cua mus rau hauv cov chaw hu ua si thib ob.

Qhov thib peb thib peb yog los them rau qhov kev ncua deb ntawm cov xaim: kom ntseeg tau ntau dua 15m, yog li kom tsis txhob muaj teeb meem hluav taws xob thiab muaj zog hluav taws xob txuas.

Kauj ruam 4 xaim: Zam kev tso cov hluav taws xob muaj zog thiab cuam tshuam.

Qhov thib tsib kauj ruam yog them nyiaj rau kev tawm tsam muaj peev xwm tiv thaiv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov kev cuam tshuam ntau li ntau tau, tshwj xeeb tshaj yog nyob rau hauv cov kev cuam tshuam nrog ntau qhov chaw cuam tshuam. Daim ntawv thov ntawm cov khoom them cov nqi ntawm cov xaim hluav taws xob yog qhov tseem ceeb, thiab daim thaiv npog txheej yuav tsum tau ua kom zoo.
