Cov ncauj lus kom ntxaws piav qhia ntawm cov laj thawj thiab kev tiv thaiv txoj kev ntawm thermocouple to feakage

Qhov laj thawj tseem ceeb rau kev to taub ntawm thermocouples yog tias cov cib rawv hauv hluav taws xob muaj rwb thaiv tsev siab. Yog li ntawd, thaum ntxig rau thermocouple nrog lub hlau raj mus rau hauv lub cub hluav taws xob uas cov cua sov ua rau nruab nrab ntawm cov hlau rauv thiab thermocouple. Qhov tseeb, refractory cib muaj cov siab thiab zoo rwb thaiv tsev thaum muaj teeb meem thaum muaj chav nyob, tab sis lawv cov kev ua haujlwm rwb yuav nce mus vim yog qhov kub txuas ntxiv.

Muaj ob peb txoj hauv kev los tiv thaiv thermocouple toreakage:
1. Nco ntsoov tias tsis muaj kev tiv tauj ntawm qhov thermocouple thiab refractory cib;
2.
3. Lub tshuab lim dej tuaj yeem ntsia tau ntawm cov zis kawg ntawm thermocouple;
4. Ncaj nraim coj tawm hauv av xaim los ntawm thermocouple ntawm kub ntsees thiab txuas rau hauv av;
5. Ntxiv cov pa roj carlicon lossis cua sov-resistant steel leeg ntawm tag nrho saum npoo ntawm thermocouple, thiab tom qab ntawd txuas lawv rau hauv av.
