Ntshav tooj liab raj yog dav siv nyob rau hauv kev lag luam cov teb loj, ntshav tooj liab tube vuam txheej txheem ntau zaus yuav cuam tshuam ncaj qha rau kev siv lub raj tooj liab, raws nraim qhov vuam yog qhov tsim nyog tshaj plaws, peb yuav tsum ua cov lus nug yooj yim.
(1) Electromagnetic welding
Nyob rau hauv qhov tsis muaj kev siab sab nraud yog thov, lub weld tawm ntawm lub hauv paus hlau rau high-temperature melting, thiab ces welded. Electrofusion welding yog siv cov cua kub ntawm qhov cua sov ntawm cov pob qij txha ntawm cov welded qhov chaw uas tsis muaj siab fuse nrog ib leeg, txias thiab solidification yuav tsim ib qho khoom sib koom ua ke.
Electrofusion vuam tuaj yeem muab faib ua: electrode arc vuam, submerged arc vuam, fusion electrode gas shielded vuam, ntsia hlau fusion electrode kem vuam thiab lwm yam. Tam sim no nyob rau hauv kev lag luam teb yog dav siv, thiab kev lag luam yog ceev, tus nqi yog me ntsis siab dua!
(2) brazing
Brazing thiab hluav taws xob vuam txoj cai yog ze heev, brazing feem ntau yuav siv ntau tshaj qhov melting point ntawm lub hauv paus cov ntaub ntawv ntawm 20 degrees los yog txawm 50 degrees qis dua cov hlau cov ntaub ntawv rau brazing khoom, cov khoom yuav tsum tau welded rhuab mus rau ib tug tej yam kub thiab txias. yog qis dua lub melting point ntawm lub hauv paus cov ntaub ntawv kub, thiab ces siv cov kua brazing cov ntaub ntawv los ntub lub hauv paus cov ntaub ntawv, thiaj li mus cuag nws nyob rau hauv qhov sib txawv ntawm qhov nruam vuam.
(3) Siab vuam
Ua ntej welding, lub vuam yuav tsum tau rhuab, thiab nyob rau hauv tej rooj plaub, nws yog pressurized. Lub siab vuam tuaj yeem muab faib ua cov vuam vuam thiab txias siab vuam, ob qho tib si siv ntau dua, rau cov kev xav tau siab dua yuav siv cov vuam vuam. Qhov kom zoo dua ntawm kev sib txuas ntawm lub siab yog tias ob qhov sib xyaw ua ke ntawm ib leeg, tom qab vuam yuav nruj nruj, yuav tsis tshua muaj qhov khoob.
Copper yeeb nkab vuam txheej txheem nyob rau hauv xyoo tas los no tau pib maj mam txhawb rau cov neeg txawj ntse, siv cov cuab yeej siv tshuab ntshiab los hloov ib nrab ntawm cov ntawv qhia ua haujlwm tau maj mam ua tiav.
Copper tube kev txheeb xyuas qhov zoo
(1) Saib cov xim thiab luster
Tam sim no nyob rau hauv kev ua lag luam qhov zoo dua cov tub yees tooj liab tube yog cov yeeb nkab tooj liab, hauv cov cua txias, kho kom zoo nkauj hauv tsev, thiab txawm tias muaj ntau lawm kuj yog siv ntau tshaj. Cov kev cai dav dav ntawm purity ntawm cov yeeb nkab tooj liab liab hauv 99% lossis ntau dua, lub npe hu ua tooj liab ntshiab, uas nthuav tawm cov xim liab liab. Qee cov yeeb nkab tooj liab liab nthuav tawm cov xim yog ib nrab rusty, ces qhov zoo ntawm cov yeeb nkab tooj liab liab no tsis zoo.
Lwm cov yeeb nkab tooj liab nyob rau hauv kev ua lag luam feem ntau yog alloy tooj liab yeeb nkab, xws li tooj dag yeeb nkab, los ntawm 7.2: 2.8 tooj liab-zinc piv synthesis, xim yuav pom daj.
(2) Tes hnov
Cov yeeb nkab zoo nkauj zoo nkauj zoo nkauj zoo nkauj, thiab tsis muaj kab nrib pleb, pob thiab lwm yam xwm txheej, thiab tsis muaj xuab zeb qhov, tsis muaj oxidation rupture thiab lwm yam tsis xws luag.
(3) Khoov tooj liab yeeb nkab
Zoo zoo tooj liab tsis yooj yim rau khoov, muaj ib tug tej yam toughness, uas yog cov tshuaj muaj pes tsawg leeg ntawm tooj liab. Tab sis tom qab qhov sib ntxiv ntawm lwm yam tshuaj rau cov yeeb nkab tooj liab, tom qab khoov, muaj cov cim tseem ceeb, thiab txawm tias xim txawv.
(4) Kev siv tshuab
Tam sim no kev tsim cov yeeb nkab tooj liab feem ntau muab faib ua cov txheej txheem extruded tooj liab yeeb nkab thiab tensile tooj liab yeeb nkab. Extruded tooj liab tube phab ntsa yog tuab, thiab los ntawm sab saum toj mus rau hauv qab, lub thickness yog sib xws. Lub phab ntsa ntawm lub raj tooj liab stretched tsis zoo li lub extruded ib qho, cov phab ntsa tsis zoo ib yam, thiab qhov nruab nrab ntawm lub raj tooj liab ntev yog nyias nyias, uas kuj yog ib qho tshwm sim.
Thaum khiav nrog R410A tub yees, ncab hom tooj liab yeeb nkab phab ntsa tuab ntawm qhov chaw tsis muaj zog yog yooj yim tawg.
(5) Txoj kev yuav khoom
Kev xaiv dav dav ntawm cov yeeb nkab tooj liab liab, peb yuav xaiv lub zos nto moo tshaj plaws, cov chaw tsim khoom loj loj, sim zam cov chaw tsim khoom me me, tib batch nqi yog tshwj xeeb tshaj yog cov lag luam qis tsis pom zoo rau kev yuav khoom. Peb tuaj yeem kawm paub ntau ntxiv txog qhov chaw ntawm tooj liab, uas ncaj qha ntsig txog qhov zoo thiab qhov tsis zoo.
