Iyini i-valve ye-inflation yemoto?
Isivalo sethangi lamanzi lokukhulisa imoto (esaziwa nangokuthi isivalo sethangi lamanzi elisizayo noma isivalo sethangi lamanzi lokukhulisa) siyingxenye ebalulekile ohlelweni lokupholisa imoto. Sifakwe ethangini lamanzi lokukhulisa (elivame ukubizwa ngokuthi "ithangi lamanzi elisizayo" noma "ithangi lokugcina uketshezi"), futhi umsebenzi waso oyinhloko ukugcina ibhalansi yokucindezela kohlelo lokupholisa, ukuqinisekisa ukuthi injini isebenza kahle ekushiseni okufanele.
Imisebenzi eyinhloko
Ukuvala nokuvimbela ukuvuza: Kuvimbela i-coolant (i-antifreeze) ekuphumeni ethangini lamanzi elinwetshiwe.
Ukuvikelwa kokukhululeka kwengcindezi: Uma ingcindezi yesistimu iphezulu kakhulu (ngokuvamile idlula i-0.12 MPa), ivalvu yokukhulula ingcindezi yangaphakathi (evame ukuvula ngengcindezi engu-0.12 MPa) ivuleka ngokuzenzakalelayo, ikhulule umusi owengeziwe ukuvimbela ukuqhuma kwamapayipi noma ukuguqulwa kwethangi lamanzi kanye neminye imonakalo emikhulu.
I-Vacuum Reflux: Ngemva kokuba injini ipholile, uhlelo lwakha ingcindezi engemihle, bese i-air valve iyavuleka, idonsela i-coolant kusuka ethangini lokunweba emuva ohlelweni lokupholisa ukuze kuvinjelwe ukuvaleka komoya kanye nokuntuleka kwe-coolant.
Izimpawu ezivamile zamaphutha
Uma isivalo sethangi lamanzi elinwetshiwe sonakele, kungase kwenzeke izimo ezilandelayo:
Isibandisi siphuma esivalweni noma ezindaweni zokuxhumanisa amapayipi;
Izinga lokushisa lenjini likhuphuka ngendlela engavamile, noma "liphinde likhuphuke";
Izinga le-coolant lehla ngokushesha;
Ukucindezela kohlelo lokupholisa akulingani, okuthinta ukusebenza kahle kokushabalaliswa kokushisa.
Iziphakamiso zokulungisa
Hlola njalo ukusebenza kokuvala kanye nokusebenza kwevalvu yesivalo;
Umjikelezo wokufaka esikhundleni ngokuvamile ungowe- noma ngokwezincomo zencwadi yemoto;
Uma ushintsha, sebenzisa isivalo sokuqala sefektri noma esikhethekile sokucindezela ukuze ugweme ukuthinta ukusebenza kwesistimu.
Nakuba isivalo sethangi lamanzi lokukhulisa sincane, sibalulekile ekuthembekeni kwesistimu yokupholisa injini futhi asinakushaywa indiva ngenxa yesimo sayo.
Isivalo sethangi lamanzi lokunwetshwa kwemoto (esaziwa nangokuthi isivalo sethangi lamanzi esisizayo noma isivalo sethangi lamanzi lokunwetshwa) siyingxenye ebalulekile ohlelweni lokupholisa injini. Imisebenzi yaso idlula ukuvala okulula. Ngokusho kolwazi lomphakathi olugunyaziwe, imisebenzi yaso eyinhloko yile elandelayo:
Umsebenzi oyinhloko
Ukuvala nokuvimbela ukuvuza: Kuvimbela i-coolant (i-antifreeze) ekuphumeni ethangini lamanzi elinwetshiwe, okuqinisekisa ukuvalwa kwesistimu yokupholisa.
Ukuvikelwa kokunciphisa ingcindezi: Lapho uhlelo lokupholisa lubhekene nokucindezela okuphezulu kokushisa (njengokuthi "ukubila ngaphezulu"), ivalvu yokunciphisa ingcindezi yesivalo (ngokuvamile evuleka ngokucindezela okungu-0.12 MPa) ivuleka ngokuzenzakalelayo, ikhipha igesi noma umusi owengeziwe ukuvimbela ukuqhuma kwamapayipi, ukuguquguquka kwethangi lamanzi, kanye neminye imonakalo emikhulu.
Ukugcina ingcindezi yesistimu izinzile: Ngokusebenzisa umthetho wokucindezela, kuphakamisa izinga lokubila kwe-coolant, kuthuthukisa ukusebenza kahle kokupholisa, ikakhulukazi ezimweni eziphakeme noma ezinomthwalo omkhulu.
Isinxephezelo sokupholisa okuzenzakalelayo: Lapho injini iphola, ivalvu ye-vacuum noma ivalvu yomoya esesivaloni iyavuleka, idonsela i-coolant ethangini lamanzi elinwetshiwe emuva ohlelweni lokujikeleza kwegazi oluyinhloko, igcina izinga loketshezi kanye nebhalansi yokucindezela.
Ukushintshashintsha kwevolumu ngenxa yokushintshashintsha kwezinga lokushisa: Kusebenzisana nomzimba wethangi lamanzi elinwetshiwe ukuze kunikezwe isikhala se-buffer sokwanda kwevolumu yesipholile okubangelwa ukushintsha kwezinga lokushisa.
Imiphumela evamile yephutha
Uma isivalo sethangi lamanzi elinwetshiwe sehluleka (njengokungakhululi ingcindezi noma ukuvalwa okubi), kungaholela ku:
Ukucindezela okuphezulu kakhulu kwesistimu yokupholisa, okubangela "ukubila ngaphezulu", ukuqhuma kwamapayipi ；
Ukulahlekelwa yi-coolant, okuholela ekushiseni ngokweqile kwenjini noma ngisho nasekubanjweni kwesilinda；
Ukuguquguquka okukhulu kwezinga loketshezi, okuthinta ukunemba kwezinzwa zokushisa.
Iziphakamiso zokulungisa
Hlola njalo ukuthi isivalo sikhubazekile noma siqhekekile yini;
Uma ushintsha, qiniseka ukuthi usebenzisa izingxenye zangempela zemininingwane yemoto efanayo;
Gcina izinga lokupholisa liphakathi kwamamaki athi "MAX" kanye "MIN" bese usebenzisa i-antifreeze ezinikele.
Qaphela: Izimoto zanamuhla ezivamile zisebenzisa kakhulu amathangi amanzi okwandisa athwala umfutho (anezivalo zamavalvu okucindezela), kuyilapho amamodeli amadala noma amanye amaJapane namaKorea angasebenzisa lawo angathwali umfutho (anezivalo ezixhunywe emoyeni).
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
