Kev Tiv Thaiv Kev Kub Kub Qhuav Technology: Thermocouple Ultra-Kev Tiv Thaiv ceev ceev rau cov cua sov
Cov kua hluav taws xob tso cua sov yog qhov ua rau muaj qhov tsis zoo ntawm qhov kub hnyiab los ntawm kev txiav tawm cov kua dej, cov kav dej thaiv thiab cov kua dej hauv lub tank poob thaum lub sijhawm ua haujlwm. Kev kub hnyiab ua rau kub ceev ceev ntawm cov cua kub ntawm cov tube qhov chaw, ua rau burnout ntawm npib tsib xee-chromium alloy cua sov cores, aging ntawm high- kub insulating txheej thiab deformation ntawm hlau tsho. Kev lag luam txhaum kev tshawb fawb qhia tau hais tias kev puas tsuaj qhuav qhuav rau ntau tshaj 65% ntawm kev tshem tawm ntxov ntxov ntawm cov dej tso cua sov, thaum siab -rhiab heev thermocouple tiv thaiv kab ke tuaj yeem yuav luag tag nrho zam qhov kev puas tsuaj irreversible.
Qhov sib txawv ntawm cov cua kub cua sov, cov cua kub ua kua tso siab tag nrho rau cov kua xov xwm rau cov cua kub dissipation thaum lub sij hawm ua hauj lwm ib txwm. Thaum cov kua dej cuam tshuam, cov cua kub dissipation nruab nrab yuav ploj mus tam sim ntawd, thiab qhov kub ntawm cov cua kub ntawm cov hlab cua kub nce los ntawm cov pa ua haujlwm kub mus txog 350℃hauv 1 thib ob. Cov hloov hluav taws xob tiv thaiv kub ib txwm muaj cov lus teb qeeb qeeb thiab tsis tuaj yeem ua tiav lub zog- tawm kev tiv thaiv nyob rau lub sijhawm, ua rau muaj hluav taws kub tam sim ntawm cov khoom cua sov.
Raws li cov ntaub ntawv pov thawj, cov kws tshaj lij thermocouple qhuav kub tiv thaiv tshuab tuaj yeem ntes qhov kub hloov pauv tsis pub dhau 0.4 vib nas this thiab ua rau lub zog tsis siv neeg - tawm haujlwm, uas yog 5-6 zaus sai dua li cov tshuab ntsuas kub ib txwm muaj. Lub ultra- cov lus teb ceev ceev tau zoo thaiv qhov kub thiab txias ua rau cov cua sov cores thiab cov txheej txheem insulating, ua thawj qhov kev nyab xeeb rau kev ua haujlwm ntawm lub rhaub dej.
Cov tshuab ua kua dej sib txawv muaj qhov sib txawv ntawm qhov kev pheej hmoo ntawm kev kub hnyiab. Qhib immersion heaters ntsib qhov kev pheej hmoo siab kub kub siab tshaj plaws vim yog cov kua dej hloov pauv yooj yim. Threaded pipeline heaters yog feem ntau ua rau cov kua dej txiav kom qhuav kub los ntawm cov kav dej thaiv. Cov flange cov cua sov muaj qhov chaw ua haujlwm ruaj khov nrog qis qis kub kub qhov tshwm sim. Thermocouple tiv thaiv rhiab heev xav tau hierarchical configuration raws li cov qauv kev pheej hmoo sib txawv.
Cov lus hauv qab no qhia txog kev tiv thaiv kev kub hnyiab qhuav ntawm cov tshuab thermocouple rau cov khoom siv hluav taws xob sib txawv:

Thermocouple qhuav hlawv kev tiv thaiv paub txog cov lus ceeb toom thaum ntxov thiab kev tiv thaiv sai ntawm cov dej kub hauv lub tshuab hluav taws xob, hloov tag nrho cov kev tiv thaiv kev tiv thaiv ntawm cov khoom siv hluav taws xob. Siab - kev tiv thaiv kev hnov mob zoo tiv thaiv kom tsis txhob muaj cov khoom siv hluav taws xob tshwm sim los ntawm cov kua dej tsis sib haum thiab txhim kho kev ua haujlwm kev nyab xeeb thiab kev ruaj ntseg ntawm cov khoom siv cua sov.
Cov txheej txheem kev tiv thaiv kev nyab xeeb tuaj yeem tsim tau raws li cov qauv ntawm lub tshuab cua sov thiab cov kev pheej hmoo ua haujlwm kom paub txog tag nrho - voj voog kev nyab xeeb ntawm cov khoom siv cua sov.
