Ithrendi ephawulekayo ku-HVAC nomhlaba weziqandisi ukuthi osonkontileka baya ngokuya belungisa izishintshi zokushisa ze-aluminium ezinesici kanye nezindololwane ezibuyisela esikhundleni soku-oda izingxenye ezintsha.Lolu shintsho ludalwe izici ezimbili: ukuphazamiseka kochungechungeni lokunikezela kanye nokwehliswa kweziqinisekiso zomkhiqizi.
Nakuba izinkinga ze-supply chain zibonakala zehlile, ukulinda isikhathi eside ukuthi izingxenye ezintsha zifike yiminyaka futhi kunzima ukuzigcina zikhona.Ngokusobala, lapho okokusebenza kungasebenzi (ikakhulukazi okokufaka esiqandisini), asinaso isikhathi sokulinda amasonto noma izinyanga ukuze sithole izingxenye ezintsha.
Nakuba izingxenye ezintsha sezitholakala kalula, ukulungiswa kusadingeka.Lokhu kungenxa yokuthi abakhiqizi abaningi baye banciphisa ama-warranty abo kumakhoyili e-aluminium njengoba bathole ukuthi iwaranti yeminyaka engu-10 ayinakutholakala nge-aluminium, okuyinsimbi encane ekwazi ukulimala kalula.Ngokuyisisekelo, abakhiqizi bathatha kancane inani lezingxenye ezisele abazithumelayo lapho benikeza amawaranti esikhathi eside.
Ithusi laliwumgogodla wezinhlelo ze-HVAC namakhoyili esiqandisi kwaze kwaba yilapho amanani ethusi enyuka ngo-2011. Eminyakeni embalwa eyalandela, abakhiqizi baqala ukuhlola ezinye izindlela futhi imboni yazinza nge-aluminium njengendlela esebenzayo neshibhile, nakuba ithusi lisasetshenziswa kwezinye izinhlelo zokusebenza ezinkulu zentengiso. .
I-soldering inqubo evame ukusetshenziswa ochwepheshe ukulungisa ukuvuza kwamakhoyili e-aluminium (bheka ibha eseceleni).Osonkontileka abaningi baqeqeshelwe ukubrasa ipayipi le-copper, kodwa i-aluminiyamu yokufaka insimbi iyindaba ehlukile futhi osonkontileka kudingeka baqonde umehluko.
Nakuba i-aluminium ishibhe kakhulu kunethusi, ibuye iveze nezinkinga ezithile.Isibonelo, kulula ukuthi ikhoyili yesiqandisi iboleke noma ibhobozeke lapho ilungisa, okwenza osonkontileka bethuke.
I-Aluminium iphinde ibe nobubanzi obuphansi bokushisa bokunamathisela, incibilika ezingeni lokushisa eliphansi kakhulu kunethusi noma ithusi.Ochwepheshe bensimu kufanele baqaphe izinga lokushisa lomlilo ukuze bagweme ukuncibilika noma, okubi nakakhulu, umonakalo ongenakulungiseka wezingxenye.
Obunye ubunzima: ngokungafani nethusi, elishintsha umbala lapho lishisa, i-aluminium ayinazo izimpawu ezibonakalayo.
Ngazo zonke lezi zinselelo, imfundo nokuqeqeshwa kwe-aluminium brazing kubalulekile.Ochwepheshe abaningi abanolwazi abazange bafunde indlela yokwenza i-aluminium braze ngoba bekungadingeki esikhathini esidlule.Kubaluleke kakhulu ukuthi osonkontileka bathole izinhlangano ezihlinzeka ngoqeqesho olunjalo.Abanye abakhiqizi banikeza ukuqeqeshwa kwamahhala kwesitifiketi se-NATE - mina nethimba lami siqhuba izifundo zokudayiswa kochwepheshe abafaka futhi balungise izinto zokusebenza, isibonelo - futhi abakhiqizi abaningi manje bacela njalo ulwazi lokudayiswa kanye neziyalezo zokulungisa amakhoyili e-aluminium avuzayo.Izikole zemisebenzi yezandla nezobuchwepheshe nazo zingahlinzeka ngokuqeqeshwa, kodwa izimali zingasebenza.
Okudingekayo nje ukulungisa amakhoyili e-aluminiyamu ithoshi elihlanganisiwe kanye nengxubevange efanele namabhulashi.Okwamanje atholakalayo ama-soldering kits aphathekayo aklanyelwe ukulungiswa kwe-aluminium, angafaka amashubhu amancane namabhulashi e-alloy ane-flux-cored alloy, kanye nesikhwama sokugcina esinamathela ku-loop yebhande.
Izinsimbi eziningi ezisodayo zisebenzisa amathoshi e-oxy-acetylene, anamalangabi ashisa kakhulu, ngakho uchwepheshe kufanele abe nokulawula ukushisa okuhle, okuhlanganisa nokugcina ilangabi likude nensimbi kunasethusi.Inhloso eyinhloko ukuncibilikisa ama-alloys, hhayi izinsimbi eziyisisekelo.
Ochwepheshe abaningi ngokwengeziwe bashintshela kumathoshi angasindi asebenzisa igesi ye-MAP-pro.Yakhiwe nge-99.5% propylene kanye ne-0.5% propane, inketho enhle emazingeni okushisa aphansi.Isilinda esiyiphawundi elilodwa kulula ukusithwala sizungeza indawo yomsebenzi, okubaluleke kakhulu ekufakweni kwesicelo esinzima njengokufakwa ophahleni oludinga izitebhisi ezikhuphukayo.I-MAP-pro cylinder ivamise ukugxunyekwa ngethoshi engu-12″ ukuze ihambe kalula eduze kwemishini elungiswayo.
Le ndlela futhi iyinketho yesabelomali.Ithoshi lingu-$50 noma ngaphansi, ishubhu le-aluminium lilinganiselwa ku-$17 (uma liqhathaniswa no-$100 noma ngaphezulu ngengxube yethusi engu-15%), kanti ithini legesi ye-MAP-pro elivela kumdayisi wezitolo lilinganiselwa ku-$10.Kodwa-ke, le gesi ivutha kakhulu futhi kuyalulekwa kakhulu ukunakekela lapho uyiphatha.
Ngamathuluzi nokuqeqeshwa okufanele, uchwepheshe angonga isikhathi esibalulekile ngokuthola amakhoyili alimele ensimini futhi awalungise ngesikhathi esisodwa.Ngaphezu kwalokho, ukulungisa kuyithuba lokuthi osonkontileka benze imali eyengeziwe, ngakho bafuna ukwenza isiqiniseko sokuthi abasebenzi babo benza umsebenzi omuhle.
I-Aluminium ayiyona insimbi eyintandokazi kochwepheshe be-HVACR uma kuziwa ekufakweni kwensimbi ngoba izacile, idonsa kakhulu kunethusi, futhi kulula ukuyibhoboza.Iphuzu lokuncibilika liphansi kakhulu kunelethusi, okwenza inqubo ye-solder ibe nzima kakhulu.Ama-solderers amaningi anolwazi angase angabi nalo isipiliyoni se-aluminium, kodwa njengoba abakhiqizi beqhubeka beshintsha izingxenye zethusi nge-aluminium, isipiliyoni se-aluminium siba esibaluleke nakakhulu.
Okulandelayo ukubuka okufushane kwezinyathelo zokunamathisela nezindlela zokulungisa izimbobo noma amanotshi ezingxenyeni ze-aluminium:
Okuqukethwe Okuxhasiwe ingxenye ekhokhelwayo ekhethekile lapho izinkampani zemboni zihlinzeka ngokuqukethwe kwekhwalithi ephezulu, okungachemile, okungekona okokuhweba ngezihloko ezithakaselayo izethameli zezindaba ze-ACHR.Konke okuqukethwe okuxhasiwe kunikezwa izinkampani zokukhangisa.Unentshisekelo yokubamba iqhaza esigabeni sethu sokuqukethwe esixhasiwe?Sicela uthinte omele indawo yangakini.
Ngesicelo Kule webinar, sizothola isibuyekezo ngesiqandisi semvelo i-R-290 kanye nomthelela waso embonini ye-HVAC.
Le webinar izosiza ochwepheshe besimo somoya ukuvala igebe phakathi kwezinhlobo ezimbili zemishini yesiqandisi, okomoya kanye nemishini yokuhweba.
