Cov ntaub ntawv muaj txiaj ntsig 丨 Kev faib tawm thiab kev txheeb xyuas cov raj tooj liab
Vim tias tooj liab thiab nws cov khoom siv alloy muaj qhov zoo xws li kev ua zoo plasticity, conductivity thiab corrosion kuj, lawv tau maj mam dhau los ua ib qho ntawm cov khoom siv dav tshaj plaws hauv tib neeg lub neej thiab kev tsim khoom hauv kuv lub teb chaws.
Cov raj tooj liab xa mus rau cov khoom siv tooj liab ua los ntawm nias lossis kos tooj liab. Lawv yog cov khoom siv tseem ceeb tshaj plaws hauv kev ua thiab kev tsim cov khoom siv tub yees. Muaj ob txoj hauv kev tseem ceeb los siv lawv.
① Ua cov khoom siv hluav taws xob. Xws li feem ntau siv evaporators thiab condensers, feem ntau hu ua "ob qho khoom siv";
② Ua cov kav dej txuas thiab cov yeeb nkab fittings.
Txawm hais tias lub hom phiaj, nws yog ib qho channel rau cov tub yees, thiab nws lub luag haujlwm tseem ceeb heev, uas yuav tsum muaj cov tshuab cua txias thiab cov tub yees siv cov tub yees siv cov raj tooj liab kom zoo.
Kev faib tawm ntawm cov raj tooj liab
Lub tshuab cua txias tooj liab tuaj yeem muab faib ua cov cua txias zoo tib yam tooj liab raj thiab degreased cua txias tooj liab raj.
Cov cua txias zoo tib yam tooj liab raj: Lub thickness feem ntau yog {{{0}}.5mm rau 2-point thiab 3-point raj, 0.6mm rau 4- point tubes, thiab 0.7mm rau 5-point thiab 6-point tubes. Feem ntau siv rau R22, lub siab tswj ntawm 0.98MPa;
Degreased cua txias tube tooj liab: tseem hu ua "deoiled cua txias tube tooj liab", {{0}}point thiab 3-point tubes yog 0.8mm tuab, 4-point , 5-point thiab 6-point yog 1.0mm tuab. Feem ntau yog siv rau cov tub yees tshiab xws li R410, lub siab yog tswj ntawm 1.8MPa;
Kev faib tawm tshwj xeeb ntawm cov khoom cua txias tooj liab tube
Oxygen-dawb tooj liab: suav nrog high-purity oxygen-dawb tooj liab (TU0, TU1, TU2) thiab phosphorus deoxidized tooj liab (TUP, TP1, TP2, thiab lwm yam), muaj cov pa oxygen thiab qee qhov impurities, tab sis tag nrho cov ntsiab lus oxygen tsis ntau tshaj 0.003%, thiab purity ntawm tooj liab yog ntau dua 99.95%. Cov khoom siv tooj liab tsis muaj pa oxygen feem ntau yog siv hauv kev lag luam hluav taws xob, xws li cov khoom siv suab, lub tshuab nqus tsev hluav taws xob, cables, thiab lwm yam.
Cov tooj liab tshwj xeeb: arsenic tooj liab, nyiaj tooj liab, tellurium tooj liab, thiab lwm yam., cov yam ntxwv yog qhov sib txawv ntawm cov kab hlau sib txuas ntxiv, xws li As, Ag, Te, thiab lwm yam, kom ua tiav lub hom phiaj ntawm kev txhim kho kev ua tiav ntawm cov khoom siv.
Oxygen tooj liab: feem ntau zoo tib yam tooj liab ntshiab (T1, T2, T3, thiab lwm yam) thiab tawv tooj liab, ntshiab tooj liab uas muaj cov pa oxygen thiab deoxidizer residue, nrog cov yam ntxwv ntawm cov pa oxygen tooj liab.
Brass tube: tooj liab-zinc alloy tube, tus lej tom qab tsab ntawv H hauv hom feem ntau sawv cev rau tus nqi nruab nrab ntawm nws cov ntsiab lus tooj liab, thiab cov ntsiab lus zinc yog qhov seem. Brass tubes ntawm ntau hom, nrog ntau dua thiab ntau dua tooj liab cov ntsiab lus, feem ntau qhia tau hais tias zoo dua thiab elongation kev ua tau zoo, feem ntau yog siv los ua cov kav dej thiab wading connectors.
Copper tube: Lub raj tooj liab siv hauv peb lub tub yees kev lag luam yog tooj liab, nrog cov ntsiab lus tooj liab ntau dua 99.90%. Nws muaj cov yam ntxwv zoo ntawm cov hlau tooj liab, cov hlau yooj yim zoo, thiab tau siv dav hauv ntau yam kev lag luam thiab kev siv pej xeem, thiab ua lub luag haujlwm tseem ceeb. Muaj peb hom: TP2, T2, thiab TU1.
