1. Kev Taw Qhia: Qhov tseem ceeb ntawm kev xaiv kom raug
Xaiv qhov tsim nyog bronze haum yog qhov kev txiav txim siab engineering uas cuam tshuam ncaj qha rau kev nyab xeeb, kev ua neej ntev, thiab kev ua haujlwm. Nrog rau ntau cov bronze alloys thiab haum configurations muaj, kev xaiv yuav tsum tau ua tib zoo xav txog ntau yam xws li cov yam ntxwv ntawm cov kua dej, kev khiav hauj lwm tej yam kev mob, thiab ib puag ncig raug. Ib qho kev xaiv tsis raug cai tuaj yeem ua rau ua tsis tiav ntxov, xau, lossis kis kab mob, ua rau raug nqi qis, kho, thiab muaj peev xwm muaj kev nyab xeeb. Cov lus qhia dav dav no muab txoj hauv kev zoo rau kev xaiv cov khoom siv tooj liab, ua kom pom kev ua haujlwm zoo thoob plaws ntau yam kev siv los ntawm cov kav dej hauv tsev mus rau kev xav tau kev lag luam thiab dej hiav txwv.IFANHoobkas 30+ xyoo tsim kev paub txog kev txhawb nqa xim / qhov loj me kev txhawb nqa dawb qauv.Zoo siab txais tos los tham rau catalog thiab kuaj dawb.Qhov no yog peb lub vev xaib Facebook:www.facebook.com.
2. Nkag siab txog Bronze Alloy Variations thiab Lawv Cov Khoom
Tsis yog tag nrho cov bronze alloys ua tau sib npaug ntawm cov ntawv thov. Cov khoom siv tooj liab feem ntau suav nrog C83600 (85-5-}5-5) rau cov kav dej dav dav, C92200 rau kev siv dej hiav txwv, thiab C95400 txhuas bronze rau cov kev xav tau siab zog. Dezincification-resistant (DZR) bronze, feem ntau raug xaiv los ua CR (corrosion resistant) tooj dag, yog qhov tseem ceeb rau cov dej siv tau los tiv thaiv kev xaiv zinc leaching. Aluminium bronze muaj lub zog zoo dua thiab tiv thaiv corrosion nyob rau hauv seawater daim ntaub ntawv, thaum silicon bronze muab zoo heev vuam yam ntxwv thiab txhua yam khoom. Nkag siab txog qhov tshwj xeeb muaj pes tsawg leeg thiab cov khoom ntawm txhua lub alloy ua rau muaj kev paub xaiv raws li daim ntawv thov kev siv tshuab, tshuaj, thiab ib puag ncig.
3. Kev soj ntsuam daim ntawv thov ib puag ncig thiab kua dej sib xws
Kev pabcuam ib puag ncig dictates bronze alloy xaiv ntau dua li lwm yam. Rau seawater thiab marine daim ntaub ntawv, txhuas bronze los yog naval tooj dag nrog superior dej ntsev yog yuav tsum tau. Hauv cov dej uas siv tau, DZR bronze lub rooj sib tham NSF / ANSI 61 daim ntawv pov thawj ua kom muaj kev nyab xeeb thiab tiv thaiv dezincification. Kev siv tshuaj ua haujlwm yuav tsum tau soj ntsuam ntawm bronze lub compatibility nrog cov acids, alkalis, thiab lwm yam tshuaj ntawm kev khiav hauj lwm kub thiab concentrations. High -cov ntawv thov kub xav tau kev xav txog ntawm bronze lub zog tuav thiab oxidation tsis kam. Ib yam li ntawd, kev nthuav tawm sab nraum zoov xav tau kev ntsuam xyuas ntawm atmospheric corrosion kuj, thaum faus daim ntaub ntawv yuav tsum xav txog av chemistry thiab electrolytic tej yam kev mob.
4. Sib piv cov hom haum rau qhov yuav tsum tau ua
Bronze fittings muaj nyob rau hauv ntau qhov kev teeb tsa, txhua qhov kev pabcuam tshwj xeeb. Threaded fittings (NPT, BSP) yooj yim disassembly thiab yog qhov zoo tagnrho rau kev saib xyuas- thaj chaw uas muaj kev sib tw. Soldered (hws) fittings muab kev ruaj khov, xau- cov pob qij txha pub dawb hauv cov kav dej. Flanged kev sib txuas haum siab - txoj kab uas hla cov kav dej thiab cov tshuab uas yuav tsum tau ua kom tsis tu ncua. Compression fittings ua haujlwm zoo rau cov kab ntsuas thiab qhov uas tsis tuaj yeem siv cua sov. Qhov kev xaiv ntawm cov hom no nyob ntawm cov kev xav tau ntawm kev teeb tsa, kev ntsuas siab, kev xav tau yooj yim, thiab kev koom ua ke nrog kev sib raug zoo nrog cov khoom siv uas twb muaj lawm. Txhua hom muaj qhov zoo sib xws uas yuav tsum ua raws li kev tsim qauv thiab kev saib xyuas cov txheej txheem.
5. Siab-Qhov ntsuas kub thiab ntsuas qhov ntsuas
Bronze fittings muaj qhov tshwj xeeb siab- qhov ntsuas kub uas txo qis thaum kub nce. Cov neeg tsim khoom muab cov ntawv qhia ntxaws ntxaws uas yuav tsum tau sab laj rau siab - daim ntawv thov kub. Sizing txuas dhau qhov nominal yeeb nkab loj kom suav nrog kev xaiv phab ntsa tuab (s teem sijhawm) rau kev ua haujlwm siab. Cov kev xav tau ntws tuaj yeem hais tag nrho - chaw nres nkoj fittings kom txo qis kev poob siab hauv cov ntawv thov tseem ceeb. Kev sizing zoo kuj tseem txiav txim siab txog kev ntsuas yav tom ntej lossis kev xeb uas yuav txo tau txoj kab uas hla dhau sijhawm. Nkag siab txog cov kev sib cuam tshuam ntawm qhov loj, siab, qhov kub thiab txias, thiab cov yam ntxwv ntws kom ntseeg tau tias qhov kev xaiv haum yuav ua rau muaj kev nyab xeeb thoob plaws hauv nws lub neej ua haujlwm.
6. Ua raws li cov qauv thiab cov ntawv pov thawj yuav tsum tau ua
Ntau yam kev lag luam tswj hwm cov qauv tshwj xeeb rau bronze fittings kom ua tau zoo thiab kev nyab xeeb. Kev siv cov kav dej hauv Teb Chaws Asmeskas feem ntau yuav tsum tau ua raws li ANSI / NSF 61 rau cov dej haus thiab ASTM B62 rau cov khoom siv tooj liab. Cov ntawv thov dej hiav txwv feem ntau siv MIL specifications lossis ABS (American Bureau of Shipping) cov qauv. Cov ntawv thov kev lag luam yuav xav tau ASME B16.15 lossis MSS SP-65 ua raws. Cov ntawv thov European feem ntau xav tau CE cim thiab ua raws li cov qauv EN cuam tshuam. Kev nkag siab txog cov kev cai no ua kom cov fittings ua tau raws li qhov tsim nyog zoo, kev nyab xeeb, thiab kev ua haujlwm zoo rau cov ntawv thov tshwj xeeb thiab kev txiav txim siab.
7. Txhim kho txoj kev txiav txim siab thiab kev sib haum xeeb
Kev xaiv tooj liab haum yuav tsum ua raws li cov txheej txheem kev teeb tsa thiab cov neeg ua haujlwm txawj. Threaded fittings xav tau kev sib txuas xov zoo thiab kev sib khi. Soldered pob qij txha xav tau hom flux tshwj xeeb thiab kev tswj cua sov kom tiv thaiv kev puas tsuaj rau cov tooj liab. Ib puag ncig kev teeb tsa tuaj yeem txwv qee txoj hauv kev- daim ntawv tso cai ua haujlwm kub rau soldering tej zaum yuav raug txwv nyob rau qee qhov chaw, nyiam cov xov los yog cov khoom siv sib txuas. Kev sib raug zoo nrog cov ntaub ntawv uas twb muaj lawm yog qhov tseem ceeb sib npaug los tiv thaiv galvanic corrosion. Tsis tas li ntawd, kev txiav txim siab txog kev saib xyuas yav tom ntej yuav cuam tshuam rau kev xaiv rau fittings uas tso cai rau disassembly yooj yim dua thiab hloov.
8. Kev txheeb xyuas tus nqi ntawm lub neej thiab kev ua haujlwm ntev -Lub Sijhawm Ua Haujlwm
Thaum tus nqi pib yog qhov kev txiav txim siab, tus nqi tseeb ntawm bronze fittings tshwm sim los ntawm kev txheeb xyuas tus nqi lifecycle. Premium alloys nrog tus nqi pib dua feem ntau muab kev ua haujlwm ntev tshaj plaws hauv kev xav tau ib puag ncig, txo qis kev hloov pauv thiab cov nuj nqis tu. Cov yam tseem ceeb suav nrog kev tiv thaiv corrosion, mechanical durability, thiab kev saib xyuas yuav ua rau muaj kev cuam tshuam tag nrho cov tswv cuab. Tsis tas li ntawd, qhov tshwm sim ntawm kev ua tsis tiav yuav tsum raug ntsuas - daim ntawv thov tseem ceeb ua kom pom tseeb kev nqis peev hauv qib siab dua - qib fittings txawm tias nce nqi pib. Qhov kev ntsuam xyuas dav no ua kom cov kev xaiv ua kom zoo tshaj qhov ua tau zoo thiab muaj txiaj ntsig kev lag luam tshaj qhov haum ntawm tag nrho cov kev pabcuam lub neej.
9. Xaus: Ib txoj hauv kev rau kev xaiv zoo
Xaiv qhov zoo bronze haum yuav tsum tau ib tug systematic ntsuam xyuas ntawm ntau yam technical es tsis yooj yim nyiam los yog kev sib piv nqi. Los ntawm kev soj ntsuam cov kev xav tau ntawm daim ntawv thov, ib puag ncig, kev ua haujlwm tshwj xeeb, thiab kev tswj hwm txoj cai, engineers thiab specifiers tuaj yeem ntseeg siab xaiv cov khoom siv tooj liab uas xa tuaj yeem txhim khu kev qha, ntev - ua haujlwm ntev. Qhov kev qhuab qhia no ua kom ntseeg tau tias cov fittings uas tau xaiv yuav tiv taus cov kev xav tau ntawm kev ua haujlwm thaum txo qis cov nqi ntawm lub neej thiab kev saib xyuas. Nyob rau hauv ib lub sijhawm ntawm kev ua kom pom tseeb ntawm kev ntseeg siab thiab kev ruaj ntseg, kev xaiv zoo bronze haum tseem yog ib qho tseem ceeb ntawm kev ua tiav cov kua dej tsim thiab kev ua haujlwm.
