Yuav ua li cas kom nce cov cua sov dissipation cheeb tsam ntawm hluav taws xob cua sov kab xev
Tso lus
Fais cua kub tracing daim kab xev yog cov khoom lag luam tshiab siab nrog ntau tshaj 20 xyoo ntawm keeb kwm. Nws cov ntawv thov yog dav heev thiab txuas ntxiv txhim kho. Tam sim no, nws yog tsuas yog siv nyob rau hauv cov chaw uas yuav tsum muaj cua sov tracing, xws li roj av, tshuaj, thiab thermal fais fab nroj tsuag. Nyob rau hauv pej xeem cov chaw, nws yog tsuas yog siv rau cua sov ntawm cov raj hluav taws kub-sib ntaus sib tua. Nyob rau hauv kev siv nyob, nws tuaj yeem siv rau sab hauv tsev cua sov (underfloof cua sov) thiab yog siv dav rau cua sov kav dej cua sov.
Yuav ua li cas nce cov cua sov dissipation cheeb tsam ntawm cov hluav taws xob cua sov tracing daim kab xev:
Hluav Taws Xob Kub Tracing Daim Kab Xev Yuav Siv Tau Rau Cua Sov Tracing Ntawm Pipeline Khoom. Cov hauv kev sib txawv yog tus yuav tsum tau ua raws li cov twj siv hluav taws xob tshwj xeeb thiab cov tshuaj tua hluav taws thiab cov roj ntsha tau zoo nyob rau hauv ntau yam kev sib tw sib npaug.
Tag nrho cov txheej txheem sib txawv no ua kom cov ntaub ntawv hluav taws xob kom ua tau kom muaj cua sov kom ntau li ntau tau kom ua tiav cov cua sov hloov. Ib qho ntxiv, peb tuaj yeem siv cov ntaub nplaum, xws li txhuas ntawv kub
Tsis tas li ntawd, qee cov ntaub ntawv tso yeeb yaj kiab, xws li yas, muaj cov thermal thermal conductivity. Txhawm rau kom lawv cov thermal conductivity, peb pom zoo kom muab lawv ua ke nrog cov ntaub qhwv fais, yog li nce cov tshav kub conduction ceev. Hluav taws xob hluav taws xob cov kais dej kub muaj cov thaiv hlau, tab sis peb yuav tsum ua kom ntseeg tau tias yog 20% qhov sib txawv ntawm qhov kub thiab txias ntawm qhov kub thiab txias.
Nyob rau hauv qhib-huab cua ib puag ncig, cov rwb thaiv tsev sab nraud ntawm cov khoom siv hlau rau kev ua cua sov tsis muaj kev ntsuas dej. Txawm hais tias cov ntaub ntawv cua sov tuaj yeem ua haujlwm txuas ntxiv, nws yuav nqus tshav kub los ntawm huab cua sov thaum tshav kub, ua rau kev kub ntxhov. Yog li ntawd, peb pom zoo kom siv cov dej tarpaulor.
