Ntaus th thermocouples: txhim khu kev qha ua tau zoo hauv cov txheej txheem kub siab

Hauv lub sijhawm ntawm cov txheej txheem kub-kev muaj kub, qhov ntsuas tau yog ntawm qhov ntsuas kub yog ntawm qhov tseem ceeb tshaj plaws. Hom r Thermocouples tau tshwm sim raws li kev daws teeb meem zoo, muab cov kev sib txawv thiab lub peev xwm uas ua rau lawv zoo rau cov ntawv thov xav tau.

Hom r thermocouples tau tsim los ntawm kev sib xyaw ntawm platinum thiab 13% rhodium. Qhov no cov kab ke tshwj xeeb no xaus rau lawv muaj kev tshwj xeeb siab - kub tsis kam. Lawv tuaj yeem ua haujlwm tau zoo nyob hauv 1768 degree, ua rau lawv tsim nyog siv hauv kev lag luam xws li iav tsim, thiab kev kho kom sov siab thiab kub thiab txias Hauv cov iav tsim tawm, piv txwv, yaj ntawm iav yuav tsum muaj kev kub siab dua 1000 degree. Hom r Thermoounles tuaj yeem tso rau hauv lub khob iav thiab muab tso rau hauv cov phab ntsa uas nyob ze rau qhov ntsuas kub, kom ua kom muaj qhov zoo viscosity thiab kev ua tau zoo thaum kev tsim khoom.

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm hom r thermocouples yog lawv qhov tseeb. Cov ntaub ntawv siv nyob rau hauv lawv cov kev tsim kho muaj ruaj khov thermoelectric cov khoom. Qhov kev ruaj khov no tso cai rau kev ua kom zoo nkauj thiab meej hloov pauv ntawm qhov sib txawv kub ua rau cov paib hluav taws xob. Nyob rau hauv cov txheej txheem siab - cov txheej txheem ntsuas kub, txawm tias yog qhov ntsuas me me nyob rau hauv kev ntsuas kub tuaj yeem ua rau cov khoom lag luam tseem ceeb hauv qhov khoom kawg. Piv txwv li, nyob rau hauv kev kho cua sov ntawm cov hlau, kev nyeem ntawv kub yog los ntawm ib hom r Thermocouple pab tau nyob rau hauv kev ua tiav cov khoom siv metallenpegical, xws li hardness, xws li hardness, lub zog, thiab ductility.

Cov thermocouples kuj pom zoo heev cov tshuaj muaj peev xwm. Nyob rau hauv kev loj - ib puag ncig kub, muaj feem ntau corrosive gases thiab lwm yam kuab lom tam sim no. Hom r thermocouples, nrog lawv platinum - Rhodium muaj pes tsawg leeg, yog cov tiv taus corrosion. Nyob rau hauv ib tug hlau smelting rauv, qhov twg lwm cov roj acidic tau tso tawm thaum lub zog smelocots thiab txuas ntxiv muab degrome kub ntsuas yam tsis tau degraded los ntawm kev xeb ib puag ncig.

Lub durability ntawm hom r thermocouples yog lwm qhov zoo dua. Lawv tsim los tiv thaiv cov kev ua kom nruj ntawm cov txheej txheem siab - cov txheej txheem ntsuas kub, suav nrog kev caij tsheb kauj vab thizling, deeg, thiab kev ntxhov siab. Nyob rau hauv ib nruam casting kev ua haujlwm hauv kev lag luam steel, cov thermocouple yog nthuav tawm cov cua sov thiab txias kom muaj vibrations los ntawm cov tshuab. Hom r Thermohoup tuaj yeem ua kom cov mob no dhau ntawm lub sijhawm ncua ntev, txo qhov xav tau ntawm cov txheej txheem kev lag luam tas li ntawm kev siv khoom.

Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias ntaus th thermocouples ua qee qhov kev txwv. Lawv kuj yog kim tau piv rau qee lwm hom ntawm thermocouples vim tias siv platinum thiab rhodium, uas yog cov hlau uas muaj txiaj ntsig. Tsis tas li, lawv qhov tseeb tuaj yeem cuam tshuam los ntawm kev kis tau los ntawm kev kis tau los ntawm kev kis tau, xws li coj lossis silicon, dhau sijhawm. Tab sis kom tsim nyog, txij nkawm, thiab kev ntsuas tsis ncaj, cov kev txwv no tuaj yeem sib haum.

Hauv kev xaus, hom r thermocous muaj kev txhim khu kev qha ua tau zoo hauv cov txheej txheem ntsuas kub. Lawv lub siab - qhov tseeb, tshuaj lom neeg ruaj khov, thiab durability ua rau lawv ib qho kev lag luam tseem ceeb rau kev tswj qhov ntsuas kub. Raws li cov txheej txheem siab - cov txheej txheem ntsuas kub txuas ntxiv mus evolve, lub luag haujlwm ntawm hom thermocouples hauv kev ua kom zoo thiab ua tau zoo ntawm cov txheej txheem no yuav nyob tseem ceeb.
