Cov raj tooj liab tau dav siv thoob plaws ntau yam kev lag luam. Cov txheej txheem vuam rau cov raj tooj liab feem ntau cuam tshuam ncaj qha rau lawv qhov kev ua tau zoo. Cia peb saib luv luv ntawm txoj kev vuam uas haum tshaj plaws.
(1) Fais Fusion Vuam
Yog tsis siv sab nraud siab, lub hauv paus hlau yog melted ntawm kub kub, ces welded. Electrofusion welding siv cov cua kub ntawm qhov chaw cua sov kom fuse qhov sib koom ua ke ntawm cov khoom siv welded yam tsis siv lub siab, ua kom muaj zog sib koom ua ke thaum txias thiab khov.
Electrofusion vuam tuaj yeem muab faib ua: shielded hlau arc vuam, submerged arc vuam, roj-shielded hlau arc vuam, thiab ntsia hlau- hom hlau arc vuam, thiab lwm yam. Nws yog dav siv nyob rau hauv cov ntawv thov kev lag luam, muab kev ua haujlwm ceev tab sis nrog cov nqi siab dua me ntsis.
(2) Brazing
Brazing qhia ib txoj hauv kev ua haujlwm zoo sib xws nrog hluav taws xob fusion vuam. Brazing feem ntau siv cov khoom muab tub lim nrog lub melting point 20℃lossis txawm 50℃qis dua cov khoom siv hauv paus. Cov ntaub ntawv yuav tsum tau welded yog rhuab mus rau ib tug kub ntawm lub hauv paus cov ntaub ntawv lub melting point, thiab cov kua muab tub lim cov ntaub ntawv wets lub hauv paus khoom, enabling nruam vuam nyob rau hauv qhov sib txawv.
(3) Siab vuam
Ua ntej welding, lub workpiece yog rhuab los yog raug kev kho mob siab. Siab vuam tuaj yeem muab faib ntxiv rau hauv kev siv vuam thiab txias siab vuam, ob qho tib si tau siv dav. Kev tiv thaiv vuam feem ntau yog ua haujlwm rau cov ntawv thov nrog cov kev xav tau siab dua. Qhov kom zoo dua ntawm kev siv vuam vuam yog tias ob qhov sib koom ua ke tsim ib daim ntawv cog lus nruj tom qab vuam, nrog qhov khoob me me.
Cov txheej txheem vuam rau cov raj tooj liab tau maj mam nce mus rau kev txawj ntse hauv xyoo tas los no, nrog cov cuab yeej siv tshuab ntshiab ib nrab hloov kev ua haujlwm ntawm phau ntawv.
Copper Tube Quality Identification
(1) Tshawb xyuas cov xim
Tam sim no, qhov zoo tshaj plaws refrigerant tube tooj liab nyob rau hauv kev ua lag luam yog tooj liab tubes, uas yog dav siv nyob rau hauv cov cua txias, kho kom zoo nkauj hauv tsev, thiab txawm industrial ntau lawm. Feem ntau, qhov purity ntawm tooj liab tubing tau teev saum toj no 99%, hu ua tooj liab ntshiab, uas nthuav tawm ib qho sawv - xim liab. Yog hais tias lub raj tooj liab zoo li xeb - xim, nws qhia tau tias tsis zoo.
Lwm cov tubing tooj liab muaj nyob rau hauv kev ua lag luam feem ntau yog alloy tooj liab tubing, xws li tooj dag tubing, uas yog tsim los ntawm ib tug 7.2: 2.8 tooj liab-zinc piv thiab qhia txog cov xim daj.
(2) Hnov qhov chaw
High-cov yeeb nkab tooj liab zoo muaj qhov zoo nkauj, tsis muaj kab nrib pleb, tsis sib xws, xuab zeb qhov, lossis oxidation tawg.
(3) Khoov lub raj tooj liab
High-cov yeeb nkab tooj liab zoo tsis yooj yim khoov thiab muaj qee qhov kev hloov pauv, uas yog cov khoom siv tshuaj lom neeg ntawm tooj liab. Txawm li cas los xij, thaum lwm cov tshuaj ntxiv ntxiv rau cov hlab ntshav liab, khoov tawm cov cim pom thiab tej zaum yuav ua rau muaj xim sib txawv.
(4) Cov txheej txheem tsim khoom
Tam sim no, kev tsim cov raj tooj liab feem ntau yog siv ob txoj hauv kev: extrusion- cov raj tooj liab ua tiav thiab kos cov raj tooj liab. Extrusion- cov kav hlau ua tiav muaj cov phab ntsa tuab, nrog cov tuab tuab los ntawm sab saum toj mus rau hauv qab. Kos cov hlab tooj liab muaj cov phab ntsa tsis sib xws, nrog cov seem hauv nruab nrab ntawm cov raj ntev dua, uas yog qhov tshwm sim ib txwm muaj.
Thaum ua haujlwm nrog R410A refrigerant, cov ntu nyias ntawm cov raj tooj liab tau ua rau tawg.
(5) Kev yuav Channel
Thaum xaiv cov raj tooj liab, nws raug nquahu kom xaiv zoo -paub, loj- teev cov tuam txhab hauv cheeb tsam thiab zam cov tuam txhab me me - nplai. Cov tuam txhab muab cov nqi qis dua rau tib batch kuj tsis pom zoo. Nws yog ib qho tseem ceeb kom nkag siab meej txog keeb kwm ntawm tooj liab, vim qhov no cuam tshuam ncaj qha rau qhov zoo.
Lub tuam txhab muaj ib pawg ntawm kev ua tooj liab ua cov kab ntau lawm hauv Suav teb, suav nrog:
German imported precision tooj liab raj ntau lawm kab (ib xyoos ib zaug ntawm 30,000 tons)
Japanese tshuab tooj liab ntawv yob kab (thinest mus txog 6μm)
Tsis siv neeg tooj liab bar nruam extrusion kab
Intelligent tooj liab ntawv thiab sawb xov zeb tsev
Digitalized tswj thiab tswj tag nrho cov txheej txheem ntau lawm yog pom los ntawm MES system, thiab qhov tseeb qhov tseeb ntawm cov khoom tuaj yeem ncav cuag ± 0.01mm.
