Kungani i-antifreeze igwebu ethangini lokunweba?

I-cylinder head gasket

Mhlawumbe imbangela evame kakhulu yegwebu ku-tank yokwandisa i-gasket evuzayo ngaphansi kwekhanda le-cylinder (ikhanda le-cylinder). Kodwa-ke, ngalokhu kungasebenzi, kunezimo ezintathu zokuthuthukiswa kwemicimbi enokubonakaliswa okuhlukene kanye namazinga ahlukene engozi emotweni.

1. Amagesi e-exhaust avela kumasilinda aqala ukungena ohlelweni lokupholisa. Kulesi simo, ukukhishwa kuzoqala ukuphoqeleka ejazini lokupholisa. Lokhu kuzokwenzeka ngoba ingcindezi ekamelweni elivuthayo izoba phezulu kunesistimu yokupholisa. Kwezinye izimo, lapho umhubhe obhotshozwe ku-gasket yekhanda lesilinda phakathi kwesilinda nejazi lokupholisa umkhulu ngokwanele, i-antifreeze izojovwa kusilinda ngesikhathi sokumuncwa ngenxa ye-vacuum. Kulokhu, kuzoba nokwehla kwezinga le-antifreeze ohlelweni kanye nokukhuphuka kwesici kusuka kumbhobho wokukhipha. Mayelana nokusebenza kwemoto, lokhu kuphazamiseka kuzozibonakalisa njengokushisa okuhlelekile kwe-motor ngenxa yamapulaki egesi. Igwebu ngokwalo ethangini lizobukeka njengamanzi anensipho aphuphumayo. I-Antifreeze ingase ibe mnyama kancane, kodwa ngeke ilahlekelwe ukucaca kanye nezakhiwo zayo zokusebenza.

2. Isekhethi yesistimu yokupholisa ihlangana nesekhethi yokuthambisa. Ezimweni eziningi, ngalokhu kuqhekeka, ukungena kuba okuhambisanayo: i-antifreeze ingena emafutheni, futhi amafutha angena epholile. Ngokuhambisanayo, kuzokwakhiwa i-emulsion eningi - inqwaba yamafutha e-beige noma ansundu, umkhiqizo wokuxuba okusebenzayo kwamanzi, i-ethylene glycol, uwoyela namabhamuza amancane omoya. I-Antifreeze, ezimweni ezithuthukisiwe kakhulu, izophenduka i-emulsion futhi iqale ukucindezelwa nge-valve yesitimu kupulaki yethangi lokunweba ngendlela ye-emulsion ye-beige liquid. Izinga likawoyela lizokhuphuka, futhi i-emulsion nayo izoqala ukunqwabelana ngaphansi kwesembozo se-valve naku-dipstick. Lokhu kuphazamiseka kuyingozi ngoba izinhlelo ezimbili ezibalulekile zenjini evuthayo yangaphakathi ziyahlupheka ngesikhathi esisodwa. Ukugcotshwa kwama-node alayishiwe kuyawohloka, ukudluliswa kokushisa kuyehla.

3. I-gasket yasha ezindaweni eziningi, futhi zonke izifunda ezintathu ezihlukene zazihlangene. Imiphumela ingaba yinto engenakulinganiswa kakhulu: kusukela ekushiseni ngokweqile kanye nokubonakala kwegwebu ku-tank yokwandisa ukuya kwisando samanzi. Isando samanzi yinto ehlotshaniswa nokunqwabelana kwenani elikhulu le-antifreeze noma olunye uketshezi kusilinda. Uketshezi aluvumeli i-piston ukuthi ikhuphuke iye phezulu endaweni efile, njengoba iyindawo engenakucindezelwa. Okungcono kakhulu, injini ngeke iqale. Okubi kakhulu, induku yokuxhuma iyagoba. Lesi simo asivamile ukubonwa kuma-ICE asemgqeni wokufuduka okuncane. Isando samanzi ngenxa ye-gasket yekhanda le-cylinder evuzayo sivame kakhulu ezinjinini ezinkulu ezimise okwe-V.

Ukuwohloka okunjalo kulungiswa kuphela ngokufaka esikhundleni se-cylinder head gasket. Kulesi simo, izinqubo ezimbili ezijwayelekile zivame ukuqhutshwa: ukuhlola ikhanda ngokuqhekeka nokuhlola izindiza zokuxhumana ze-block kanye nekhanda le-cylinder. Uma kutholakala ukuqhekeka, ikhanda kufanele lishintshwe. Futhi lapho uchezuka endizeni, indawo yokukhwelana yebhulokhi noma ikhanda iyapholishwa.

Ezinye izizathu

Kukhona ukungasebenzi kahle okubili okuphendula umbuzo: kungani i-antifreeze igwebu ethangini lokunweba.

1. Uketshezi lwekhwalithi engalungile noma empofu ohlelweni. Icala langempela laziwa lapho umshayeli ozimele, kodwa ongenalwazi ethela uketshezi olujwayelekile lokuwasha ingilazi enamakha ohlelweni lokupholisa. Ngokwemvelo, ingxube enjalo ayigcini nje ngokufaka ithangi elincane futhi yanyathelisa umkhondo waleli phutha elingenangqondo, kodwa ngenxa yobukhona be-surfactant, igwebu. Amaphutha anjalo awabalulekile futhi ngeke aholele ekuhlulekeni okubukhali kwenjini yomlilo yangaphakathi. Kufanele nje usule isistimu futhi ugcwalise isipholile esivamile. Icala elingavamile namuhla, kodwa i-antifreeze ingase futhi igwebe ethangini lokunweba ngenxa yekhwalithi ephansi.
2. Ukushisa ngokweqile kwenjini ngokungasebenzi kanyekanye kwe-valve yesitimu. Kulokhu, ukuchaphazwa kwengxenye yesipholile ngamavalvu ngendlela yokuhiliza, inqwaba yegwebu kubonakala. Ngaphansi kwezimo ezijwayelekile, lapho i-valve kupulaki isesimweni esihle, isipholile, lapho sishisa ngokweqile, sizophuma ngamandla futhi ngokushesha siphume ohlelweni. Uma ipulaki ingasebenzi njengoba kufanele, khona-ke lokhu kungaholela ekuqhekekeni noma ekuqhekekeni kwamapayipi avela ezihlalweni ngisho nokubhujiswa kwe-radiator.

Isiphetho lapha silula: ungasebenzisi uketshezi olungafanele ohlelweni lokupholisa futhi uqaphe izinga lokushisa lemoto.
