Momwe mungakonzere chubu chowongolera mpweya wagalimoto ndi manja anu

Freon imagwiritsidwa ntchito ngati firiji mu makina oyendetsa mpweya wamagalimoto, omwe ali ndi madzi ambiri ndipo amatha kulowa mkati mwa kuwonongeka pang'ono. Kutayika ngakhale kachigawo kakang'ono ka ndalama zonse kumachepetsa kwambiri kuzizira kwa mpweya mu kanyumba.

Ngati chilemacho chimakhala ndi maonekedwe a mng'alu kapena dzenje laling'ono mu chitoliro chachikulu, ndiye kuti mpweya umachoka kwathunthu, komanso pamodzi ndi mafuta odzola.

Chifukwa chiyani mapaipi a air conditioner amayamba kulephera

Machubu amakono amapangidwa ndi aluminiyamu yokhala ndi mipanda yopyapyala ndipo alibe malire achitetezo.

Pakhoza kukhala zifukwa zingapo zopangira kutayikira:

• dzimbiri kunja ndi mkati, zotayidwa ndi aloyi zochokera pa izo nthawi zonse kutetezedwa ndi oxide wosanjikiza, koma ngati akuphwanyidwa ndi mankhwala kapena makina njira, chitsulo mwamsanga amachitira ndi zinthu zambiri ndi kuwonongedwa;
• kugwedera katundu, ma aloyi ena kuwala ndi Chimaona mu ukalamba ndipo mosavuta yokutidwa ndi maukonde microcracks;
• kuwonongeka kwamakina pa ngozi, kuwongolera kolakwika kapena kuyika kosayenera popanda kutetezedwa kuzinthu zakunja;
• machubu amapukutidwa mwamsanga pamene kumangiriza kwawo kumawonongeka ndipo mbali zozungulira zimakhudzidwa.

Nthawi zambiri, zowonongeka sizimazindikirika bwino, ziyenera kufufuzidwa ndi zizindikiro zosalunjika kapena njira zowunikira.

Momwe mungadziwire kuwonongeka kwa chubu

Nthawi zina, poyang'ana misewu yayikulu, mutha kuwona mitsinje yamafuta, yomwe ndi gawo la freon powonjezera mafuta. Koma imakondanso kusanduka nthunzi pakapita nthawi kapena kubisika ndi dothi lakunja.

Kuti mudziwe bwino malo owonongeka, chipinda cha injini chimatsukidwa, pambuyo pake dongosololo limakanizidwa ndi utoto wapadera, womwe umawoneka bwino mu kuwala kwa nyali ya ultraviolet.

Ikhozanso kuwonjezeredwa ku mapangidwe a refrigerant kuti mudziwe zizindikiro za kuchepa kwapang'onopang'ono panthawi ya ntchito.

Njira zokonzera

Njira yabwino kwambiri yokonza ndikusintha chubu chomwe chakhudzidwa ndi gawo loyambirira. Izi sizotsika mtengo kwambiri, koma zodalirika, gawo lopuma lotereli lili ndi gwero lofanana ndi msonkhano wa conveyor, ndipo ndi mwayi waukulu kuti sizidzabweretsa mavuto mpaka kumapeto kwa moyo wautumiki wa galimotoyo.

Pogula gawo, muyenera kusankha nthawi yomweyo mphete za O zopangidwa ndi zitsulo zokhala ndi mphira wosanjikiza wogwiritsidwa ntchito ndi manambala amndandanda, ndizotayidwa.

Koma sikuti nthawi zonse zimakhala zotheka kupeza gawo loyenera loyenera. Makamaka pamagalimoto akale, osowa. Ndi anthu ochepa amene amafuna kuyembekezera kutha kwa nthawi yobereka mu nyengo. Chifukwa chake, matekinoloje okonzanso amitundu yodalirika angagwiritsidwe ntchito.

Kuwotcherera kwa Argon arc

Kuphika zotayidwa ndi aloyi ake si kophweka, ndendende chifukwa cha mofulumira mapangidwe okusayidi filimu yomweyo pamwamba pake. Chitsulocho chimagwira nthawi yomweyo ndi oxygen, yomwe imakhalapo nthawi zonse mumlengalenga. Makamaka pa kutentha kwambiri, zomwe zimafuna njira za soldering kapena kuwotcherera.

Kuwotcherera kwa aluminium kumachitika ndi zida zapadera m'malo a argon. Pachifukwa ichi, mwayi wa okosijeni ku msoko umachotsedwa ndi kutuluka kosalekeza kwa mpweya wa inert, ndipo kudzazidwa kwa zolakwika kumatsimikiziridwa ndi kuperekedwa kwa zinthu zodzaza zomwe zimaperekedwa mu mawonekedwe a ndodo zamitundu yosiyanasiyana ya mankhwala.

Kugwira ntchito ndi zida za argon sikungatheke nokha, zidazo ndizokwera mtengo kwambiri, ndipo ndondomeko yokhayo imafuna chidziwitso ndi ziyeneretso zambiri.

Ndikosavuta kuchotsa chubu chowonongeka ndikugwiritsa ntchito ntchito za wowotcherera akatswiri. Ngati chiwonongekocho ndi chimodzi, koma kawirikawiri chubu imasungidwa bwino, ndiye kuti gawo lokonzedwa motere silidzakhala loipa kuposa latsopano.

Konzani zosakaniza

Kuti mukonze mwachangu, mutha kugwiritsa ntchito nyimbo za epoxy monga "kuwotcherera kozizira" ndi mabandeji olimbikitsa. Njirayi siyimasiyana ndi kudalirika ndipo sizikhala nthawi yayitali, izi zitha kuonedwa ngati muyeso wanthawi yochepa chabe. Koma nthawi zina zimakhala zotheka kupeza mgwirizano wamphamvu komanso wolimba mokwanira.

Mulimonsemo, chubucho chiyenera kuchotsedwa ndikutsukidwa bwino kuchokera ku dothi, mafuta ndi ma oxides. Pofuna kupatsa mphamvu chigambacho, kulimbikitsana ndi zipangizo za nsalu, mwachitsanzo, pogwiritsa ntchito fiberglass, zimagwiritsidwa ntchito.

Bandeji ya fiberglass imapangidwa, kulimba kwake kumatsimikiziridwa ndi mtundu wa kuyeretsa ndi kumamatira kwa pawiri pazitsulo pamwamba pazitsulo. Kuti mugwirizane bwino, dzenje kapena ming'alu imadulidwa mwamakani.

Zida zopangidwa kale

Nthawi zina ndizoyenera kusintha chubu chachitsulo ndi payipi ya rabara ndi malangizo, kapena kupanga nokha. Pali zida zogwirira ntchito ngati izi. Zimaphatikizapo machubu, zokometsera, chida cha crimping.

Ngati ma hoses osinthika akugwiritsidwa ntchito, ndiye kuti zinthuzo ziyenera kukhala zapadera, izi ndizitsulo zolimbitsa mphira zotsutsana ndi freon, mafuta, kutentha kwakukulu ndi kutsika, komanso kupirira kupanikizika pamzere ndi malire.

Nyimbo zodziwika bwino zokonzera chubu chowongolera mpweya

Zolemba zingapo zimatha kusiyanitsa, kutengera luso la kukonza.

Kuwotcherera chitoliro cha mpweya pamalopo. Kukonza chubu. Aluminiyamu kuwotcherera. kuwotcherera TIG

Kukonza solder

Amagwiritsa ntchito nyali ya gasi ya propane ndi solder ya aluminiyamu ya Castolin. Pali kale kusinthasintha mkati mwa ndodo yodzaza, kotero ntchitoyo imachepetsedwa kuti ikhale yokonzekera pamwamba, kukonza ndi kutentha chubu ndi nyali.

Pamene solder imasungunuka, zinthuzo zimalowa mu zowonongeka pamwamba, kupanga chigamba cholimba chachitsulo chomwe chimayikidwa bwino mu khoma la chubu. Zina mwazochitikira ndi aluminiyamu brazing zidzafunika, koma kawirikawiri zimakhala zosavuta kuposa kuwotcherera ndipo sizifuna zipangizo zodula.

poxipol

Mtundu wotchuka wa epoxy wochokera ku South America, womwe umagwiranso ntchito pa aluminiyamu. Kukonzekera kotereku sikungakhale kodalirika, koma ndikugwiritsa ntchito mosamala, pali milandu yodziwika bwino yokonza mapaipi, yomwe idatenga nthawi yayitali. Ndalama zake ndizochepa, ndizotheka kuyesa.

GoodYear hoses

Zida zopangira, ma hose ndi zogwiritsira ntchito zilipo kuti mupange chosinthira chanu chosinthira machubu a aluminiyamu. Ma hoses ndi freon-resistant, kulimbikitsidwa, kusunga mphamvu yoyenera.

Mudzafunika chida chapadera - crimper, crimping nsonga. Mukhoza kusankha kukula koyenera kwa mitundu yosiyanasiyana ya machubu okhazikika, komanso mphete zosindikizira zopangidwa ndi rubberized zitsulo za diameter zosiyanasiyana.

Malangizo odzigwiritsira ntchito

Kuti akonze mwachangu, amaloledwa kugwiritsa ntchito ukadaulo wogwiritsa ntchito bandeji ya fiberglass pa epoxy guluu.

Mutha kugwiritsa ntchito Poxipol yotchuka.

• pamwamba pa malo olakwika amatsukidwa mosamala, amatsukidwa ndi sandpaper, chitsulocho chimadulidwa pang'ono ndi nsonga ya scalpel;
• chigawo cha zigawo ziwiri chosakanikirana motsatira malangizo chimagwiritsidwa ntchito kumalo okonzerako ndi bandeji yopyapyala ya fiberglass;
• nsaluyo imakulungidwa pa chubu ndikupaka pamwamba;
• bandejiyo imagwiridwa mwamphamvu kwa mphindi khumi mpaka zomatirazo polima.

Ndikofunikira kugwira ntchito ndi magolovesi, zigawo za epoxy ndizoopsa ndipo zimayambitsa kupsa mtima kwapakhungu. Pawiriwu amauma mofulumira, makamaka pa kutentha kwambiri yozungulira.

"KUWOGWIRITSA" THE REDUCER NDI POXIPOL - KODI IDZAGWIRA NTCHITO?

Pakachitika vuto panjira, ndikofunikira kuyimitsa chowongolera mpweya nthawi yomweyo, ngati makinawo sachita izi kale pa chizindikiro chochokera ku sensor yokakamiza. Kupanda kutero, kugwiritsa ntchito kompresa popanda mafuta kungayambitse kuwonongeka kosasinthika ndipo msonkhanowo uyenera kusinthidwa ngati msonkhano.
