Yuav ua li cas kho lub thermocouple tawg nyob rau hauv hluav taws xob ceramic rauv

1. Muaj nuj nqi thiab cov qauv ntawm hluav taws xob ceramic rauv thermocouples
Hluav taws xob ceramic rauv thermocouple yog ib qho kev siv qhov kub thiab txias, feem ntau yog siv los ntsuas qhov kub hauv qhov cub hluav taws xob ceramic. Nws muaj ob hom hlau hlau, feem ntau yog platinum resistors thiab npib tsib xee resistors, uas txuas ua ke los tsim ib lub voj voog. Thaum qhov kub hloov pauv, tus nqi kuj ntawm cov hlau hlau kuj hloov raws li.
2. Yog vim li cas rau thermocouple breakage
Thaum siv cov thermocouples, vim qhov kub ua haujlwm siab, cov khoom siv hlau tau yooj yim cuam tshuam los ntawm thermal expansion thiab thermal stress. Lub sij hawm ntev thermal expansion thiab contraction tuaj yeem ua rau muaj kev puas tsuaj rau cov thermocouples. Tsis tas li ntawd, cov thermocouples tseem raug cuam tshuam rau sab nraud quab yuam xws li kev cuam tshuam, khoov, thiab ncab, ua rau tawg ntawm cov hlau hlau.
3. Kho txoj kev thermocouple tawg
Yog hais tias lub thermocouple ntawm hluav taws xob ceramic rauv tawg, nws yuav tsum tau kho. Cov kev kho tshwj xeeb yog raws li hauv qab no:
Ua ntej, cov khoom siv ntawm qhov chaw tawg thiab lub zog ntawm lub tshuab hluav taws xob lub tshuab hluav taws xob yuav tsum raug txiav tawm kom ntseeg tau tias muaj kev nyab xeeb.
Tom qab ntawd, siv cov cuab yeej hluav taws xob los ntxuav cov thermocouple tawg thiab sim tshem tawm cov impurities thiab vuam slag txuas rau nws.
Tom ntej no, nrhiav cov khoom siv vuam tsim nyog thiab cov khoom siv los vuam cov thermocouple tawg. Ua ntej, nws yog ib qho tsim nyog los ntxuav thiab kho cov xaim ntawm ob qho kawg ntawm lub thermocouple kom muaj kev sib txuas. Tom qab ntawd, txuas cov xov hlau ua ke kom ntseeg tau tias cov pob qij txha tau ruaj khov thiab txhim khu kev qha.
Tom qab ntawd, siv cov ntaub ntawv insulating los insulate cov ntsiab lus vuam kom paub meej tias cov teeb meem kev nyab xeeb xws li luv luv Circuit Court lossis to tsis tshwm sim dua.
4. Ceev faj
Thaum lub sij hawm kho ntawm thermocouple breakage, cov ntsiab lus hauv qab no yuav tsum tau muab sau tseg:
Ua ntej ua txhua yam kev tu thiab kho, nws yog ib qho tsim nyog yuav tsum tau txiav tawm lub hwj chim ntawm lub lauj kaub tais diav kom muaj kev nyab xeeb ntawm tus kheej thiab cov khoom siv.
Thaum welding, nws yog ib qho tseem ceeb kom paub cov txheej txheem vuam kom raug kom tsis txhob muaj kev puas tsuaj ntxiv rau cov thermocouples uas tshwm sim los ntawm qhov kub thiab txias ntau dhau los yog lub sijhawm vuam ntev.
Lub thermocouple kho yuav tsum tau soj ntsuam zoo kom ntseeg tau tias cov vuam yog ruaj khov thiab txhim khu kev qha, thiab ntsuas nws cov nqi tsis kam rau kev ua haujlwm ib txwm muaj.
Kev kho ntawm tawg hluav taws xob ceramic rauv thermocouples yuav tsum tau ua tib zoo ua haujlwm, ua ntej kom muaj kev ruaj ntseg, tom qab ntawd vuam kho, thiab kev tshuaj xyuas zoo. Kev kho raws sij hawm ntawm cov thermocouples tawg tuaj yeem ua kom muaj kev tswj xyuas qhov kub thiab txias ntawm lub tshuab hluav taws xob ceramic thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv.
