Irediyetha yemoto: "Umqaphi wokulawula izinga lokushisa" kanye nomhlahlandlela wokuxazulula izinkinga
I-radiator yemoto, eyaziwa ngokwesayensi ngokuthi i-radiator, iyisici esiyinhloko sesistimu yokupholisa yemoto futhi ingabhekwa "njengomqaphi wokulawula izinga lokushisa" wenjini. Kubonakala sengathi iyisici sensimbi nje esinamapayipi amancane, kodwa idlala indima ebalulekile ekugcineni ukusebenza okuvamile kwenjini.
Ngokombono womsebenzi oyinhloko, umsebenzi oyinhloko we-radiator ukupholisa nokunciphisa izinga lokushisa lenjini ngokujikeleza kwe-coolant. Uma injini isebenza, ifana "ne-heater" enamandla kakhulu, ekhiqiza ukushisa okukhulu, okuthi cishe u-30% - 40% wokushisa udinga ukuhlakazwa ohlelweni lokupholisa. Ngemva kokumunca ukushisa okuvela emzimbeni wesilinda ejakethini lamanzi lenjini, i-coolant igeleza iye ku-radiator, lapho idlula khona emaphinini okushisa ku-radiator, futhi, ngokuphefumula okuphoqelelwe kokunyakaza kwemoto noma ifeni yokupholisa, idlulisela ukushisa emoyeni. I-coolant epholile ibe isingena kabusha ekujikelezeni kwenjini ukuqinisekisa ukuthi izinga lokushisa lokusebenza kwenjini lihlala lizinzile ngaphakathi kwebanga elifanele lika-85℃ - 105℃. Le nqubo ingavimbela ngempumelelo amaphutha amakhulu njengokuminyana kwe-piston kanye nokuguqulwa kwesilinda okubangelwa ukushisa ngokweqile kwenjini, futhi ivimbele nokwehla kokusebenza kahle ngenxa yokusebenza kwezinga lokushisa eliphansi.
Ngaphezu komsebenzi oyisisekelo wokupholisa, i-radiator nayo inemisebenzi eminingi yokusiza. Ingagcina ibhalansi yokucindezela kohlelo lokupholisa. I-valve yokucindezela esesivaloni se-radiator, enomfutho ongu-100 - 150 kPa, ingaphakamisa iphuzu lokubila le-coolant libe ngu-120℃, ivimbele ukuqhuma kwamapayipi futhi yenze imoto iphephe uma ushayela ngesivinini esiphezulu ehlobo. Ngaphezu kwalokho, i-antifreeze ku-radiator ingakha ifilimu yokuvikela yensimbi, inciphise ukugqwala kwephampu yamanzi namapayipi, futhi ivimbele ukwehla okungu-30% ekusebenzeni kahle kokupholisa kungakapheli iminyaka emi-3. Amanye amamodeli anowoyela wokudlulisa okuzenzakalelayo, ukupholisa uwoyela osizayo wokuqondisa, kanye nokupholisa uhlelo lokupholisa umoya nakho kuncike emsebenzini wokubambisana we-radiator.
Kodwa-ke, lo "mqaphi wokulawula izinga lokushisa" nawo ungaba yingozi, okubangela izingozi ezingaba khona ekusebenzeni kwemoto. Ukungasebenzi kahle kwerediyetha okuvamile kuhlanganisa izinhlobo ezilandelayo.
Okokuqala, ukuvuza kwe-coolant. Uma i-radiator inezimfa, izivalo ezonakele, noma amajoyinti epayipi axegayo kanye namapayipi erabha agugile, i-coolant izovuza. Uma ukuvuza kukhulu, kuzovela amaconsi amanzi engxenyeni yenjini, futhi i-coolant enganele izoholela ngqo ekupholeni okubi kwenjini kanye nokwenyuka okukhulu kwezinga lokushisa, okubangela ukukhanya kwesixwayiso sokushisa kwamanzi kudeshibhodi ukuthi kukhanye. Isibonelo, amamodeli afana ne-Audi Q5 kanye ne-BYD Song avame ukuba nezinkinga zokuvuza kwethangi lamanzi, okungase kubangelwe ukuqongelela kwesikali samanzi ngenxa yokusetshenziswa isikhathi eside, ukudlidliza ngesikhathi sokushayela okubangela umonakalo wepayipi, noma ukwakheka kwesikali samanzi ngenxa yokusetshenziswa kwe-antifreeze engaphansi kwesikhathi eside.
Okwesibili, ukuvaleka kwerediyetha. Ukuvaleka kwangaphandle kubangelwa kakhulu yimfucumfucu efana namaqabunga, izinambuzane, kanye ne-willow fluff enamathela ezimpikweni zerediyetha, okuthinta ukugeleza komoya futhi kunciphisa umphumela wokupholisa. Ukuvaleka kwangaphakathi kuvame ukwenzeka ngenxa yokwakheka kwendle ngokusebenzisa i-antifreeze ephansi noma isikali samanzi esakhiwe ukusetshenziswa kwamanzi ompompi isikhathi eside, okuvimba amapayipi okupholisa. Ukuvaleka kuzobangela ukugeleza kwe-coolant okungekuhle, kuvimbele injini ekuqedeni ukushisa ngesikhathi, futhi kamuva kubangele amazinga okushisa aphezulu.
Okwesithathu, ukushisa kakhulu kwenjini. Lokhu kuvame ukuba ukubonakaliswa okuqondile kokwehluleka kwe-radiator. Ngaphandle kwezimbangela zokuvuza nokuvaleka okungenhla, ukwehluleka kwephampu okuholela ekujikelezeni koketshezi lokupholisa okunganele, ukuminyana kwe-thermostat kanye nokungakwazi ukushintsha phakathi kokujikeleza okukhulu nokuncane, kanye nokufakwa komoya ohlelweni lokupholisa ukuze kuphazamise ukujikeleza kokupholisa, konke kungabangela ukushisa kakhulu kwenjini. Uma kungaphathwa ngokushesha, kungaholela emiphumeleni emibi njengokuncibilika kwama-piston rings nama-valve plates, kanye nokuguqulwa kwesilinda, kanye nezindleko zokulungisa eziphezulu.
Ukuze kugwenywe ukwehluleka kwethangi lamanzi okuphazamisa ukusebenza kwemoto, abanikazi bezimoto kufanele benze ukulungiswa njalo. Kufanele bahlole njalo izinga le-coolant, baqinisekise ukuthi liphakathi kwamamaki athi "MIN" kanye "MAX" ethangini lamanzi elinwetshiwe. Faka uhlobo olufanayo lwe-coolant uma lunganele. Gwema ukusebenzisa i-coolant evela kumikhiqizo ehlukene. Yishintshe njalo ngokwezidingo zemoto ukuze uvimbele ukwakheka kwesikali samanzi. Ngesikhathi esifanayo, kufanele bahlanze njalo ubuso be-radiator ukuze basuse udoti onamathiselwe futhi bagcine amaphiko okushabalalisa ukushisa ehlanzekile futhi engaphazanyiswa.
Uma ubona izimpawu zokwehluleka kwethangi lamanzi, njengokukhanya kwesixwayiso sokushisa kwamanzi edeshibhodini, ukwehla okungaqondakali kwe-coolant, noma umhwamuko wamanzi omhlophe ophuma engxenyeni yenjini, kufanele kuthathwe izinyathelo ezisheshayo. Okokuqala, thola indawo ephephile yokupaka imoto, ugcine injini isebenza ngesivinini esingasebenzi ukuze uqede ukushisa, bese uvula i-hood yenjini ukuze wandise izinga lokushabalalisa ukushisa. Ungayicimi injini ngokushesha noma uvule isembozo se-radiator ngokushesha ukuze ugweme ukusha. Ngemuva kwalokho, xhumana nabasebenzi bokulungisa abangochwepheshe ngokushesha ukuze uthole imbangela yephutha bese wenza ukulungisa.
Nakuba ithangi lamanzi lemoto lingaphawuleki, lihlobene nokuphila kwenjini kanye nokuphepha kokushayela kwemoto. Ukuqonda umsebenzi wayo, ukunaka ukubaluleka kokugcinwa kwansuku zonke, kanye nokusingatha amaphutha ngokushesha kungaqinisekisa ukuthi lo "mqaphi wokulawula izinga lokushisa" usebenza njalo nangokuzinzile, uvikela injini.
