Siab thaiv vuam tshuab yog cov txheej txheem tseem ceeb uas sib npaug ntawm kev txhim kho kev ruaj ntseg thiab tom qab kho yooj yim ntawm sheathed thermocouples. Kev ua haujlwm vuam tsis tu ncua xws li tag nrho- lub voj voog vuam, ntsaws vuam thiab qhov ruaj khov tsis tu ncua- taw tes vuam yog qhov ua rau muaj qhov cuam tshuam ntawm qhov sib tsoo, kaw qhov tuag ntawm cov ntsia hlau nres thiab nyuaj disassembly thiab hloov tom qab siv. Kev lag luam - tau hais txog peb - cov txheej txheem sib tsoo qhov chaw vuam yog tib txoj kev tsim qauv rau kev txhim kho siab, uas tuaj yeem ua kom cov qauv ruaj khov thaum ua tiav qhov chaw ua haujlwm rau kev tu cov cuab yeej.
Tus txheej txheem peb -sided chaw welding txheej txheem txais cov txheej txheem kev ntxhov siab symmetric welding, uas kho lub siab thaiv los ntawm peb txoj kev sib txawv. Txoj kev vuam no tuaj yeem tsim kho kom ruaj khov thiab sib npaug ntawm kev ntxhov siab ntawm lub siab thaiv lub cev, kom tsis txhob muaj cov cuab yeej hloov chaw thiab loosening tshwm sim los ntawm ib qho - ib sab vuam kev nyuaj siab concentration. Nyob rau hauv ntev -lub sij hawm siab - kub thiab siab - kev co kev lag luam ib puag ncig, peb -sided qhov chaw vuam qauv tuaj yeem tiv taus thermal deformation kev nyuaj siab, kua cuam tshuam quab yuam thiab tshuab kev co, kom ntseeg tau tias lub siab thaiv tsis hloov, deform lossis poob, thiab tuav ntev - lub sij hawm kho qhov ruaj khov ntawm cov thermoco.
Qhov tseem ceeb tshaj plaws txwv tsis pub ua haujlwm hauv kev siv vuam yog qhov chaw vuam ntawm qhov chaw nres nkoj thermocouple. Qhov chaw nres nkoj yog cov tub ntxhais channel rau kev sib dhos sensor, disassembly, debugging thiab hloov. Vuam ntawm txoj hauj lwm no yuav ua rau hauv cheeb tsam siab -kub thermal deformation ntawm qhov chaw nres nkoj aperture, ua rau aperture shrinkage, cov qauv distortion thiab vuam seem thaiv. Thaum deformed thiab thaiv, lub thermocouple tsis tuaj yeem muab tso rau hauv thiab muab rho tawm kom zoo, thiab txawm tias tsis muaj qhov cuam tshuam tas mus li yuav tshwm sim, ua rau cov khoom siv tom qab kho thiab hloov tsis tau thiab ua rau ntev - lub sij hawm ntau lawm raug kaw rau cov lag luam.
Qhov chaw welding kev tsim kho yuav tsum nruj me ntsis kom tsis txhob vuam qhov nres ntsia hlau tuag. Cov ntsia hlau nres yog ib qho tseem ceeb txwv kev tiv thaiv los tswj qhov tob qhov tob thiab qhov chaw ruaj khov ntawm cov thermocouple sheathed, uas ua haujlwm tseem ceeb ntawm kev tso chaw, xauv thiab tiv thaiv - txav chaw. Yog tias cov ntsia hlau nres yog welded thiab tsau thaum lub sij hawm vuam, cov ntsia hlau yuav plam tag nrho nws cov kev kho thiab disassembling muaj nuj nqi. Lub thermocouple tsis tuaj yeem kho qhov tob qhov tob raws li kev hloov pauv ntawm kev ua haujlwm, thiab tsis tuaj yeem muab tshem tawm rau kev kho thiab calibration, zoo heev txhim kho cov khoom siv tom qab kev ua haujlwm thiab cov nqi tu.
Cov kws tshaj lij tsawg-tam sim no thiab luv luv-lub sijhawm siv lub tshuab vuam tshuab yuav tsum tau txais kev pom zoo hauv kev tsim kho tiag tiag kom txo tau cov vuam kub tawm thiab zam tag nrho cov thermal deformation ntawm lub siab thaiv. Tom qab vuam, tag nrho cov vuam caws pliav thiab burrs yuav tsum tau polished smoothly kom tsis txhob khawb lub thermocouple sheath thaum lub sij hawm ntxig thiab rho tawm. Kev tshuaj xyuas dua ntawm cov ntsia hlau yooj yooj yim thiab qhov chaw nres nkoj smoothness tom qab vuam ua kom cov khoom tsis muaj kev cuam tshuam thiab sib dhos. Standard peb-sided chaw vuam specifications zoo kawg nkaus sib npaug installation firmness thiab txij nkawm yooj yim, uas yog ib qho tseem ceeb cov txheej txheem rau siab - zoo installation ntawm sheathed thermocouples.
