Qhov kev tshaj tawm blog no yuav coj koj mus txog txhua yam koj xav paub txog kev xaiv txoj cai tooj liab yeeb nkab lossis raj rau koj qhov project.
Tau txais cov ntaub ntawv qhia ntxaws ntxaws
Dab tsi yog Copper Pipes lossis Tubes?
Cov kav dej tooj liab thiab cov raj yog cylindrical hollow piping feem ntau siv hauv cov dej, dej, cua txias, cua sov tshuab, hluav taws xob tiv thaiv hluav taws xob, thiab lwm yam kev siv cov kav dej thiab kev lag luam. Lawv muaj zog heev nrog lub neej ntev vim lawv tsis kam tiv thaiv corrosion thiab muaj peev xwm tiv taus qhov kub thiab txias. Tooj liab muaj cov thermal conductivity zoo, yog li nws feem ntau nyiam dua cov yas lossis hlau rau qee yam kev siv thaum tshav kub kub. Raws li qhov txiaj ntsig ntawm cov txiaj ntsig no, cov kav dej tooj liab thiab cov raj tau dav suav tias yog cov khoom siv txhim khu kev qha tshaj plaws rau cov kav dej thoob ntiaj teb.
Cov lus qhia txog kev xaiv cov yeeb nkab tooj liab zoo meej lossis raj rau koj qhov project
Qhov loj me:
Cov kav dej tooj liab thiab cov raj tuaj yeem sib txawv, thiab nws yog ib qho tseem ceeb rau xaiv qhov loj me nyob ntawm seb koj qhov project yuav tsum tau ua. Qhov luaj li cas ntawm koj cov yeeb nkab tooj liab lossis lub raj yuav feem ntau nyob ntawm daim ntawv thov. Piv txwv li, yog tias koj tab tom tsim cov kav dej, koj yuav tsum xav txog cov yeeb nkab txoj kab uas hla thiab phab ntsa thickness. Ntawm qhov tod tes, rau HVAC systems, koj yuav tsum xav txog cov yeeb nkab nominal loj. Koj tuaj yeem pom cov qauv sizing tau yooj yim hauv cov ntawv teev cov yeeb nkab tooj liab, thiab koj tuaj yeem sab laj nrog koj tus neeg cog lus los pab koj xaiv qhov loj me rau koj qhov project.
Hom: Cov kav dej tooj liab lossis cov raj xa tuaj rau ntau hom, raws li hauv qab no:
a) Hom K:Hom no yog qhov tuab tshaj plaws thiab feem ntau siv rau kev pabcuam hauv av. Nws yog qhov kim tshaj plaws ntawm tag nrho cov kav dej tooj liab.
b) Hom L:Hom ntau tshaj plaws hauv cov kav dej hauv vaj tse feem ntau yog txheeb xyuas los ntawm nws cov xim xiav. Hom L tooj liab raj muaj phab ntsa tuab uas yog 1/8 nti tuab thiab yog siv rau cov kav dej, HVAC, thiab compressed cua tshuab.
c) Hom M:Hom no yog siv nyob rau hauv cov kav dej hauv tsev rau kev siv dej kub thiab dej txias. Nws thickness yog kwv yees li 1/16 nti.
d) AC / tub yees:Hom no yog siv rau lub tshuab cua txias thiab tub yees, thiab nws yog annealed rau dabtsi yog khoov.
Cov txheej txheem koom nrog:
Thaum koj tau xaiv qhov loj thiab hom ntawm cov yeeb nkab tooj liab uas koj xav tau, cov kauj ruam tom ntej yog xaiv cov txheej txheem sib koom ua ke. Ntau txoj hauv kev yog siv los koom nrog cov kav dej tooj liab lossis cov raj, nrog rau kev sib txuas, kev sib txuas, compression haum, thiab nias- haum kev sib txuas. Soldering yog siv lub teeb los ua kom sov qhov sib koom ua ke thiab yaj lub solder los tsim kom muaj kev sib raug zoo. Brazing zoo ib yam li soldering tab sis yuav tsum melting tooj dag es tsis txhob siv solder. Compression fittings yog ib qho yooj yim rau nruab tab sis tej zaum yuav tsis tuav ib yam nkaus li nyob rau hauv siab -siab tshuab. Xovxwm- haum kev sib txuas tau nrov dua vim lawv muaj kev nyab xeeb, ua haujlwm tau zoo, txhim khu kev qha, thiab tsis tas yuav muaj cov cuab yeej tshwj xeeb.
Kev tu:
Cov kav dej tooj liab lossis cov kav dej yog qhov kev xaiv zoo tshaj plaws rau cov kav dej thiab HVAC vim tias lawv tau ntev - kav ntev, ruaj, thiab corrosion- tiv taus. Txawm li cas los xij, lawv xav tau kev saib xyuas tsis tu ncua kom ntseeg tau tias lawv txuas ntxiv ua haujlwm kom raug. Kev saib xyuas tsis tu ncua suav nrog kev tu, rwb thaiv tsev kom zoo, thiab kev tshuaj xyuas tsis tu ncua txhawm rau txheeb xyuas thiab kho cov xau ua ntej lawv ua rau muaj kev puas tsuaj loj.
Xaiv txoj cai tooj liab yeeb nkab los yog raj rau koj qhov project yuav daunting, tab sis nws tsis tas yuav. Xav txog qhov loj me, hom, thiab kev sib koom ua ke thaum xaiv cov kav dej tooj liab lossis cov raj rau koj qhov project. Tham nrog koj tus neeg cog lus kom paub tseeb tias koj xaiv cov ntaub ntawv tsim nyog tshaj plaws thiab cov txheej txheem los ua kom tiav koj qhov project kom tiav. Los ntawm kev ua raws li cov lus qhia hauv cov ntawv blog no thiab tswj xyuas koj cov kav dej tooj liab lossis cov raj tsis tu ncua, koj tuaj yeem xyuas kom koj cov kav dej lossis HVAC ua haujlwm tau zoo rau ntau xyoo.
