Zamkatimu
funso momwe mungayang'anire antifreeze, ndi yofunikira osati panthawi yomwe ikugwira ntchito kwa nthawi yayitali muzitsulo zoziziritsa, koma, choyamba, pogula chozizira chatsopano. Kupatula apo, kugwiritsa ntchito antifreeze yabodza kapena yomwe yataya katundu wake idzasokoneza zigawo zonse za dongosolo lozizira.
Magawo omwe amayenera kuyezedwa ngati antifreeze ndi momwe zimakhalira, kuzizira, kuwira. Izi zitha kuchitika kunyumba pogwiritsa ntchito kutentha, multimeter ndi hydrometer. Pamene cheke ikuchitika mu dongosolo kuzirala palokha, m'pofunika kuonetsetsa kuti palibe mafuta ndi mpweya mu antifreeze, kuti palibe kutayikira, komanso mlingo wake mu thanki yowonjezera. Momwe mungachitire zonsezi molondola ndikuwerenga mwachangu m'nkhaniyi.
Momwe mungayang'anire mulingo wa antifreeze
Kudzaza / kuwonjezera antifreeze, komanso kuyang'anira mlingo wake mu dongosolo, kumachitika pogwiritsa ntchito thanki yowonjezera. Nthawi zambiri, pa thanki pamakhala zizindikiro MAX ndi MIN (nthawi zina ZODZALA ndi LOW), zomwe zimawonetsa kuzizira kwambiri komanso kuchepera. Koma nthawi zina pamakhala MAX yokha, nthawi zambiri palibe zizindikiro pa thanki, kapena imakhala yosavutikira kotero kuti ndizosatheka kuwunika kuchuluka kwamadzimadzi, osatchulanso momwe alili.
Kwa iwo omwe sadziwa antifreeze, amayang'ana kutentha kapena kuzizira, yankho ndi - kuzizira kokha! Izi zili choncho chifukwa cha zinthu ziwiri. Choyamba ndi chakuti antifreeze imakula ikatenthedwa ndipo mulingo wake udzawoneka wapamwamba. Chachiwiri - kuyang'ana kutentha ndi koopsa, chifukwa mukhoza kudziwotcha nokha.
Zowopsa zochepa komanso zochulukirapo pa thanki
Momwemo, mulingo wa antifreeze uyenera kukhala pafupifupi 1-2 cm pansi pa chizindikiro chachikulu. Ngati palibe zizindikiro pa thanki, ndiye kuti thanki yowonjezera imadzazidwa ndi antifreeze pafupifupi theka la voliyumu. Chabwino, cheke, motero, chiyenera kuchitidwa mwachiwonekere. Ngati thanki ndi yakuda, gwiritsani ntchito ndodo kapena chinthu chachitali chopyapyala.
Ngati antifreeze siidumphira paliponse, ndiye kuti mulingo wake susintha kwa nthawi yayitali, chifukwa umazungulira mu dongosolo losindikizidwa ndipo sungathe kusuntha kulikonse. Kutsika pang'ono kumatha kuwonetsa kutayikira ndipo sikukuwoneka kwenikweni, kotero kuti madziwo amatha kulowa mu masilindala.
Pamene chekeyo inasonyeza kuti mlingowo ndi wapamwamba kuposa momwe uyenera kukhalira, ndiye kuti izi ziyenera kuperekedwanso, makamaka ngati zimakula pang'onopang'ono kapena mpweya (thovu) umatuluka mu thanki yowonjezera kapena radiator. Nthawi zambiri izi zimasonyeza kusweka kwa silinda mutu gasket. Zotsatira zake, mlingo umakwera chifukwa cha mpweya kapena mafuta. Mutha kuyang'ana mafuta mu antifreeze mowoneka, pokhudza choziziritsa. Mipweya ya antifreeze imawunikidwa kudzera mu fungo (fungo la mpweya wotulutsa mpweya), komanso pobowola madzi mu thanki. Ndi kuchuluka kwa liwiro, kuchuluka kwa thovu mu thanki yowonjezera kudzawonjezeka. pofuna kudziwa ngati pali mpweya mu antifreeze, njira ntchito kufufuza kukhulupirika kwa yamphamvu mutu gasket.
Nthawi zambiri, eni magalimoto "Hyundai Solaris" ndi "Kia Rio", komanso magalimoto ena amtunduwu amakumana ndi zovuta kuyang'ana mulingo wa antifreeze. Izi ndichifukwa choti thanki yawo ilinso pamalo ovuta kwambiri, monga momwe idapangidwira yokha.
