Tus ua haujlwm ua haujlwm ntawm cov hluav taws xob hnyav thauj khoom caj npab
Tus txheej txheem ua hauj lwm ntawm lub chaw thau khoom hluav taws xob yog npaj ua kom sov thiab ruaj khov rau cov raj hluav taws xob, ntau li cov raj xa dej, thiab lwm yam. Qhov no txwv tsis pub muaj qhov nruab nrab los ntawm kev ncaj ncees, ua rau visccosity, lossis crystallizing vim muaj kev nce qib ntau dhau, ua kom muaj kev nce qib kev txhim kho kom nruj thiab tsis hloov chaw.
Tshwj xeeb, nws cov tub ntxhais ua haujlwm ua haujlwm yog raws li hauv qab no:
Kub Qhuav: Lub taub ntim hluav taws xob tapes tau tso rau ntawm cov chaw ntawm cov pipelines xws li cov yeeb nkab sab nraud thiab kab rov tav ntawm lub chaw thau khoom. Thaum energized, hluav taws xob tracing tapes Hloov hluav taws xob hluav taws xob mus rau hauv lub zog hluav taws xob, hloov mus rau lub raj xa hluav taws.
Tswj Qhov Kub: Lub kaw lus tau nruab nrog qhov kub-hnov lus kub xws li thermal resesors los saib qhov kub ntawm lub sijhawm kub ntawm lub sijhawm tiag tiag, thiab pub lub cim rov qab mus rau qhov kub tswj tau qhov kub. Raws li cov teeb meem ntsuas kub, tswj hwm hluav taws xob tau kho cov zis hluav taws xob ntawm cov hluav taws xob uas yuav tsum muaj (piv txwv li, saum toj no qhov tseem ceeb los tiv thaiv qhov nruab nrab hauv qhov chaw tsawg-qhov chaw muaj dej khov).
Thaum tshav kub kub conduction thiab txij nkawm: Cov cua sov tsim los ntawm cov hluav taws xob tapes yog ua los ntawm cov raj xa hluav taws xob mus rau qhov nruab nrab ntawm qhov nruab nrab thaum ib puag ncig cua sov dissipation thiab lwm yam. Qhov no tswj cov fellity ntawm nruab nrab, kom pom tseeb tias nws tuaj yeem ntws ncaj qha los ntawm cov cuab yeej thauj khoom lossis cov cuab yeej thauj mus thaum thauj khoom thiab thauj khoom.
Qhov kev ua haujlwm no ua rau muaj kev thauj hluav taws xob ua haujlwm tsis muaj kev cia siab rau qhov chaw thau khoom thiab siv hluav taws xob yooj yim, thiab kub dua thiab kub thiab txias. Li no, lo lus nug no tshwm sim.
