Pali njira ziwiri zazikulu zogwiritsira ntchito chitoliro cha mkuwa potenthetsa mpweya: (1) kupanga chosinthanitsa kutentha.Monga momwe zimagwiritsidwira ntchito evaporator, condenser, yomwe imadziwika kuti "chipangizo ziwiri";(2) Kupanga mapaipi olumikizira ndi zolumikizira.Chifukwa chake chubu chamkuwa chimatchedwanso "air conditioning" "chotengera chamagazi", "chotengera chamagazi" chabwino ndi cholakwika chimasankha mwachindunji mtundu wa mpweya wabwino.Choncho, ubwino wa kuwotcherera chitoliro chamkuwa umatengedwanso mozama.Lero tigawana nkhani ya copper chubu kuwotcherera refrigeration air conditioning heat exchanger.
Ntchito yokonzekera
1. Werengani ndikudziwa bwino zojambula za zomangamanga;
2, mawonekedwe a malo omanga - kuwona ngati malo omangawo ali ndi momwe amagwirira ntchito;
3. Kukonzekera mapaipi ndi zowonjezera;
4. Kukonzekera zida ndi zida zoyezera - oxygen-acetylene, cutter, hacksaw, nyundo, wrench, mlingo, tepi muyeso, fayilo, etc.
2. Kuyika ndondomeko
1) Kuwongolera chitoliro chamkuwa: kugogoda pang'onopang'ono pathupi la chitoliro ndi nyundo yamatabwa kuti muwongole chitoliro ndi gawo.Powongola, samalani kuti musamapangitse mphamvu zambiri, musamapangitse zizindikiro za nyundo, maenje, zokopa kapena zizindikiro zowonongeka pamwamba pa chitoliro.
2) kudula chitoliro: kudula chitoliro chamkuwa kungagwiritsidwe ntchito hacksaw, chopukusira, chodula chitoliro chamkuwa, koma osati mpweya - kudula kwa acetylene.Kukonzekera kwa chitoliro chamkuwa pogwiritsa ntchito fayilo kapena makina a beveling, koma osati mpweya - kukonza moto wa acetylene.Padi yamatabwa iyenera kugwiritsidwa ntchito mbali zonse za vise pomanga chitoliro cha mkuwa kuti chitolirocho chisadulidwe.
3, kumaliza kuyeretsa
Sipadzakhala mafuta, okusayidi, banga kapena fumbi pamwamba pa chubu chamkuwa cholowetsedwa mu olowa, apo ayi zidzakhudza kwambiri kuwotcherera kwa solder kuzitsulo zoyambira ndikuyambitsa zolakwika.Choncho, pamwamba ayenera kupukuta ndi organic solvents.Kulumikizana kwa chitoliro chamkuwa nthawi zambiri kumakhala kopanda dothi, ngati pali burashi yawaya yamkuwa yogwiritsidwa ntchito ndi chitsulo chachitsulo chomata, sichingasinthidwe ndi zida zina zodetsedwa.
Gwiritsani ntchito sandpaper kuchotsa mafuta, oxide, madontho, ndi fumbi pamwamba pa cholumikizira pomwe chubu chamkuwa chimayikidwa.
