Chiitiko chinocherechedzwa muHVAC uye nyika yefiriji ndechekuti makondirakiti ari kuwedzera kugadzirisa akaremara aluminium heat exchanger uye kudzorera magokora pane kuodha zvikamu zvitsva.Shanduko iyi imhaka yezvikonzero zviviri: kukanganisa mune cheni yekugovera uye kuderedzwa kwemugadziri waranti.
Nepo nyaya dzezvekutengesa dzichiita kunge dzadzikira, kumirira kwenguva refu kuti zvikamu zvitsva zvisvike makore uye zvakaoma kuchengeta mustock.Zviripachena, kana midziyo ikakundikana (kunyanya midziyo yefiriji), hatina nguva yekumirira mavhiki kana mwedzi yezvikamu zvitsva.
Nepo zvikamu zvitsva zviri kuwanikwa zviri nyore, kugadzirisa kunoramba kuri kudiwa.Izvi zvinodaro nekuti vagadziri vazhinji vakadzikisa zvirango zvavo pamakoiri ealuminium sezvo vakaona kuti waranti yemakore gumi haigoneki kune aruminiyamu, inova simbi yakatetepa inogona kukuvara nyore.Chaizvoizvo, vagadziri vanorerutsa huwandu hwezvimedu zvavanotumira kana vachipa waranti yenguva refu.
Mhangura ndiyo yaive musana weHVAC masisitimu uye mafiriji coils kusvika mitengo yemhangura yakwira muna 2011. Mumakore mashoma akatevera, vagadziri vakatanga kuyedza dzimwe nzira uye indasitiri yakagadzika paaluminium sechinhu chinoshanda uye chakachipa, kunyangwe mhangura ichiri kushandiswa mune mamwe makuru ekutengesa maapplication. .
Soldering inzira inowanzoshandiswa nenyanzvi kugadzirisa zvinobuda mumakoiri ealuminium (ona sidebar).Mazhinji makondirakiti akadzidziswa kusungira pombi yemhangura, asi brazing aluminium inyaya yakasiyana uye makondirakiti anofanirwa kunzwisisa mutsauko.
Kunyangwe aluminium yakachipa zvakanyanya kupfuura mhangura, inopawo mamwe matambudziko.Semuenzaniso, zviri nyore kuti coil yefiriji ibviswe mazino kana kugochwa painogadzirisa, izvo zvinonzwisisika zvinoita kuti makontrakta atye.
Aluminium zvakare ine yakaderera soldering heat range, inonyunguduka pane yakaderera tembiricha kupfuura ndarira kana mhangura.Nyanzvi dzemumunda dzinofanirwa kutarisa kudziya kwemurazvo kudzivirira kunyungudika kana, zvakanyanya, kukuvadza kusingagadzirike kune zvikamu.
Imwe dambudziko: kusiyana nemhangura, iyo inoshandura ruvara kana inopisa, aluminium haina zviratidzo zvemuviri.
Nezvese matambudziko aya, aluminium brazing dzidzo uye kudzidziswa kwakakosha.Vazhinji vane ruzivo matekiniki havana kudzidza kugadzira aluminium nekuti yaisadikanwa kare.Zvakakosha kuti makondirakiti atsvage masangano anopa dzidziso yakadai.Vamwe vagadziri vanopa mahara eNATE certification kudzidziswa - timu yangu neni tinomhanyisa makosi ekutengesa kune matekiniki anoisa nekugadzirisa michina, semuenzaniso - uye vagadziri vazhinji izvozvi vanogara vachikumbira ruzivo rwekutengesa uye mirairo kugadzirisa macoil aruminiyamu ari kubuda.Zvikoro zvehunyanzvi uye zvehunyanzvi zvinogona kupawo dzidziso, asi mubhadharo unogona kushanda.
Zvese zvinodikanwa kugadzirisa macoil ealuminium mwenje wesolder pamwe chete nearoyi yakakodzera uye mabhurashi.Parizvino iripo inotakurika solder kits yakagadzirirwa kugadziriswa kwealuminium, iyo inogona kusanganisira mini-tubes uye flux-cored alloy mabhurashi, pamwe nebhegi rekuchengetedza rinonamatira kune bhandi loop.
Masimbi akawanda anosunga anoshandisa mazhenje oxy-acetylene, ane moto unopisa zvikuru, saka nyanzvi inofanira kuva nekutonga kwakanaka kwekupisa, kusanganisira kuchengeta murazvo uri kure nesimbi kupfuura kubva mumhangura.Chinangwa chikuru ndechekunyungudutsa alloys, kwete masimbi epasi.
Vanamazvikokota vakawanda vari kushandura tochi dzakareruka dzinoshandisa MAP-pro gasi.Yakaumbwa ne99.5% propylene uye 0.5% propane, isarudzo yakanaka kune yakaderera tembiricha.Iyo one-pound silinda iri nyore kutakura yakatenderedza nzvimbo yebasa, iyo inonyanya kukosha pakuda maapplication akadai sekuisa padenga remba zvinoda kukwira masitepisi.Iyo MAP-pro cylinder inowanzoiswa ne 12 ″ torch kuitira nyore kufamba uchitenderedza midziyo iri kugadzirwa.
Iyi nzira zvakare isarudzo yebhajeti.Torch i$50 zvichidzika, chubhu yealuminium ingangoita madhora gumi nemanomwe (ichienzaniswa nemadhora zana kana kupfuura pa15% yemhangura alloy), uye gaba reMAP-pro gasi rinobva kumutengesi rinoita madhora gumi.Nekudaro, gasi iri rinopfuta zvakanyanya uye kutarisirwa kunorairwa zvakanyanya pakuribata.
Nematurusi akakodzera uye kudzidziswa, nyanzvi inogona kuchengetedza nguva yakakosha nekutsvaga makoiri akakuvadzwa mumunda uye kuita kugadzirisa mukushanya kumwe chete.Pamusoro pezvo, kugadziridza mukana kune makondirakiti kuita mari yakawedzerwa, saka vanoda kuve nechokwadi chekuti vashandi vavo vari kuita basa rakanaka.
Aluminium haisi simbi inofarirwa nevarapi veHVACR kana zvasvika pakusoda nekuti yakatetepa, yakapfava kupfuura mhangura, uye iri nyore kubaya.Iyo yakanyunguduka yakanyanya kuderera kupfuura yemhangura, iyo inoita kuti soldering ive yakaoma.Vazhinji vane ruzivo solderers vangave vasina ruzivo rwealuminium, asi sezvo vagadziri vachiwedzera kutsiva zvikamu zvemhangura nealuminium, ruzivo rwealuminium runotonyanya kukosha.
