Dab Tsi Yog Hluav Taws Xob Hlau?

Mar 30, 2018

Qhov hluav taws xob hlau siv hluav taws xob (EMT) yog ib qho hnyav, siv los qhwv cov xov hluav taws hauv cov qauv. Txawm hais tias muaj qee qhov lwm cov khoom yeeb nkab, hom no yog ib qho ntawm ntau txoj kev xaiv los ntawm tus kws kho mob, vim nws yog tus nqi ntau dua cov ntaub ntawv zoo sib xws. Cov hlau thiab txhuas yog siv los ua ob lub ntsiab ntawm cov kav dej, thiab feem ntau nws yog galvanized nrog zinc coating kom corrosion resistant. EMT tsis txuas nrog rau lwm txoj kev xaiv nyob hauv ntau lub raj hluav taws xob, tab sis ob qho tag nrho ob qho kev txuas mus rau ntawm lub teeb.

Lub raj yog txoj cai xaiv tshaj plaws rau sab hauv tsev thiab sab nraum zoov, vim nws yog lub teeb pom kev zoo hauv cov khw. Vim hais tias nws yog ib qho hwm hlau qauv, uas tswj cov kev tsim ntawm tag nrho txoj kev. Qhov tseeb, ntau qhov chaw qhia tias EMT yuav tsum siv lub zog hluav taws xob uas ua tau raws li tus qauv tsim. Cov kav hlau uas tsis yog xim hlau kuj yog qhov yooj yim dua rau kev ya raws, uas yog ib qho txaus ntshai heev ntawm hluav taws xob. Cov teebmeem ntawm raug rau cov tshuaj vapor lossis cov kev tivthaiv ntawm qhov ua rau lo lus yuam kev yuam kev kuj siv rau qhov yeeb nkab no, thiab txawm tias lub teeb hlau plating zoo dua li ntawm txhua tus.

Lwm qhov laj thawj rau cov neeg tsim khoom siv hluav taws xob hlau hlawv ntau dua lwm cov ntaub ntawv yog qhov yooj yim rau nruab. Kev tsim kho cov neeg ua haujlwm feem ntau muaj chaw seem me me los txhim kho cov haujlwm hauv lub raj, thiab qee qhov hloov loj yog qhov nyuaj tshaj. Nyob rau hauv qhov chaw nkag los yog lub qab nthab, lub tshuab nqa lub tshuab nqa nruab siab tuaj yeem tsim kho kom ceev, zoo, muaj kev ruaj ntseg thiab khoob khoob. Vim tias EMT kuj muaj qee yam ua kom yooj yim, nws muaj peev xwm muab ntsia tau rau hauv lwm daim teb, txwv tsis pub nws yuav ua tsis tau. Lwm cov kev zoo dua yog tias nws yog feem ntau galvanized, thiab nws kuj yog tsim rau kev tsim kho rau sab nrauv ib puag ncig.

Lub tshuab hluav taws xob hlau kuj muaj nws cov teeb meem, thiab nws tsis pom zoo rau txhua daim ntawv thov. Thaum siv cov xov hlau loj, piv txwv li, cov neeg lag luam yuav xav siv txoj kev tiv thaiv hluav taws xob (RMC) los yog cov khauj khes hluav taws xob (GMC) kom muaj kev tiv thaiv zoo. Lub teb yuav tsum muaj ntau txoj hlua thiab curves, uas yuav zoo dua rau cov hlau nplaum hlau (FMT) los yog cov hluav taws xob hlau ntxig (FMC), vim lawv tuaj yeem khiav lag luam txhua lub, tab sis nyob ruaj khov. Cov vaj tsev nyob tsis muaj feem ntau wired nrog tubing hauv daim ntawv no, nws yog siv los ua lag luam hauv tsev.
