Mafuta opangira mpweya wamagalimoto - kusankha malinga ndi malamulo onse
Zamkatimu
Oyendetsa galimoto ambiri akuyesera kuthetsa nkhani ya machitidwe a mpweya wabwino. Pankhaniyi, muyenera kusankha mafuta opangira ma auto-conditioner kuti mupewe kuwonongeka mtsogolo.
Mafuta owongolera mpweya - osavulaza bwanji?
Masiku ano, m'makampani ogulitsa magalimoto pali mafuta ambiri opangira mpweya m'galimoto. Kusankhidwa kwa gawoli kuyenera kutengedwa ndi udindo, chifukwa izi siziri zazing'ono, monga zikuwonekera poyamba. Ndikoyenera kudziwa kuti m'ma air conditioners a galimoto, mosiyana ndi ma air conditioners ena a firiji ndi kukhazikitsa, amagwiritsa ntchito machubu a aluminiyamu ndi zisindikizo za mphira pazitsulo, zomwe, ngati zitasokonezedwa kapena kudzazidwa ndi zolakwika, zimatha kutaya katundu wawo ndikulephera.
Ngati mwangozi kusakaniza mitundu iwiri yosiyana ya mafuta, izo mosalephera kuyambitsa flocculation mu mizere galimoto yanu. Ndipo kale vutoli likhoza kuthetsedwa kokha mu utumiki wa galimoto, ndipo matenda oterowo ndi kuyeretsa adzawononga dalaivala ndalama yokongola. Ichi ndichifukwa chake ndikofunikira kudziwa zonse zobisika pakugwira ntchito kwa air conditioner.
Synthetic ndi mchere - timasankha pamaziko
Pali magulu awiri amafuta a makina owongolera mpweya - ma synthetic ndi mineral compounds. Sizovuta kudziwa kuti ndi iti yomwe imatsanuliridwa mu chowongolera galimoto yanu, koma bizinesi iyi imafunikira zidziwitso zina. Magalimoto onse omwe amapangidwa isanafike 1994 amathamanga pa R-12 freon. Mtundu uwu wa freon umasakanizidwa ndi mafuta amchere a Suniso 5G.
Magalimoto opangidwa pambuyo pa 1994 amagwira ntchito kokha pa R-134a freon, yomwe imagwiritsidwa ntchito pamodzi ndi mankhwala opangidwa ndi PAG 46, PAG 100, PAG 150. Mitunduyi imatchedwanso polyalkyl glycol. Mafuta a freon a R-134a sangakhale amchere, opangidwa okha. M'zochita, pali zochitika zina pomwe mu 1994 magalimoto adapangidwa ndi ma compressor omwe angagwiritsidwe ntchito R-12 ndi R-134a freon.
Koma muyenera kukumbukira kuti ngakhale galimoto yanu itagwa mu nthawi ya kusintha, simuyenera kudzaza mchere pambuyo pa polyalkyl glycol - motere mpweya wanu wa galimoto sukhalitsa. Makina owongolera mpweya wa mafakitale (magawo a refrigeration) amagwira ntchito pa R-404a freon ndikugwiritsa ntchito mafuta opangira firiji a POE, omwe mu mawonekedwe ake amafanana kwambiri ndi mafuta a gulu la PAG.
Mafuta amtunduwu sayenera kusakanizidwa kapena kusinthidwa ndi wina ndi mnzake.
Chifukwa cha mapangidwe ake, mtundu wa mafakitale wa compressor ya air conditioner sunapangidwe kuti usamalidwe ndipo ukhoza kulephera. Mtundu wa PAG uli ndi drawback imodzi - imakhutitsidwa mwachangu ndi chinyezi panja., kotero amapangidwa m'zitini zazing'ono, zomwe sizikhala zokwanira nthawi zonse zowonjezera zowonjezera za air conditioner.
Magulu agalimoto - lingaliro kwa dalaivala
Magwero a galimoto adzakuthandizaninso kudziwa kuti ndi mafuta ati omwe ayenera kutsanuliridwa mu mpweya wanu wozizira. Chifukwa chake, pamsika wamagalimoto aku Korea ndi Japan, mitundu ya PAG 46, PAG 100 imagwiritsidwa ntchito, pamsika wamagalimoto aku America, makamaka PAG 150, pamagalimoto aku Europe, mtundu wodziwika kwambiri ndi PAG 46.
Ngati mwaganiza kusintha mafuta, koma inu simukudziwa buku la dongosolo, mu nkhani iyi Ndi bwino kuyeretsa kwathunthu injini ya galimoto air conditioning kompresa. Njirazi ndizofunikira kuti muwonetsetse kuti palibe zonyansa zamakina komanso kuti makina anu ndi opanda mpweya. Pokhapokha mungathe kuwonjezera kuchuluka kwa mafuta omwe mukufuna. Musanawonjezere mafuta, tikulimbikitsidwa kudzaza dongosolo ndi gawo la kuchuluka kwa mafuta kuti mupewe kugwedezeka kwamafuta mu compressor.
Magiredi onse ali ndi ma viscosity coefficients osiyanasiyana, ndipo makina ambiri amagalimoto amalimbikitsa kukulitsa koyenera iyi chifukwa cha kusintha kwanyengo chaka chonse, chifukwa izi zimachepetsa kukhuthala. Ichi ndichifukwa chake anthu ambiri amagwiritsa ntchito mtundu wamafuta wa PAG 100 - nyengo yathu, kapangidwe kake kamakhala ndi mphamvu yabwino kwambiri yama viscosity.
Chilichonse chomwe angakuuzeni m'masitolo ndi mautumiki, kumbukirani kuti mafuta am'firiji achilengedwe alibe chilengedwe. Kwa kompresa ya galimoto yanu mpweya wofewetsa, muyenera kugwiritsa ntchito mtundu analimbikitsa wa mafuta, amene analamula mu buku utumiki wanu. Ndipo pakakhala zovuta kwambiri za air conditioner, muyenera kulumikizana ndi akatswiri.
