Qhov ua rau ntawm thermocouple leakage muaj xws li:
(1) Lub refractory cib ntawm lub cub hluav taws xob muaj cov rwb thaiv tsev tsis zoo ntawm qhov kub thiab txias. Ntxig ib lub thermocouple nrog lub raj hlau rau hauv cov phab ntsa ntawm lub cub tawg nrog rau lub tshuab hluav taws xob tuaj yeem ua rau lub tshuab hluav taws xob thiab cov thermocouple sib cuag tau yooj yim. Lub refractory cib yog ib qho zoo rwb thaiv tsev disassembly ntawm chav tsev kub. Tab sis raws li qhov kub thiab txias, qhov kev ua haujlwm rwb thaiv tsev yuav txo qis heev. Alumina refractory cib feem ntau yog siv rau hauv ob sab phlu ntawm cov hluav taws xob tiv thaiv hluav taws xob, thiab tus nqi kuj txo qis thaum kub nce.
(2) Kev sib cuag ntawm lub cub tawg hlau thiab cov thermocouple. Lub platinum-rhodium thermocouple tiv thaiv raj yog alumina porcelain raj, thiab ob peb hlau yog hnav nrog lub plooj (porcelain tube) rau kev sib cais thiab rwb thaiv tsev. Lub rwb thaiv tsev kev ua tau zoo kuj tseem yuav raug txo qis ntawm qhov kub thiab txias, ua rau cov dej xau, thiab thaum kawg xau mus rau lub thermoelectric Nyob rau hauv qhov chaw, muaj AC to teeb liab ntawm lub thermocouple.
Cov txheej txheem los tiv thaiv cov dej ntws ntawm thermocouple:
(1) Khaws cov thermocouple tsis txhob sib cuag nrog cov cib refractory.
(2) Hauv pem teb qhov tsis zoo ntawm lub thermocouple kom tshem tawm cov teeb liab tawm ntawm lub thermocouple.
(3) Nruab ib lub tshuab lim ntawm qhov tso zis kawg ntawm lub thermocouple.
(4) Ua cov xaim hauv av los ntawm qhov kub sib txuas ntawm lub thermocouple mus rau hauv av.
(5) Ntxiv lub raj kub-resistant steel raj lossis silicon carbide raj rau lub raj thermocouple thiab hauv av.
