Indawo yokusebenza kunye nomgaqo wefeni yokupholisa imoto
1. Xa i-sensor yeqondo lokushisa kwi-tank (enyanisweni i-valve yokulawula ubushushu, kungekhona i-sensor ye-gauge yeqondo lokushisa) ifumanisa ukuba iqondo lokushisa letanki lidlula umgubasi (ubuninzi be-95 degrees), i-fan relay idibanisa;
2. Isekethe ye-fan ixhunyiwe nge-fan relay, kwaye i-motor motor iqala.
3. Xa isivamvo sobushushu setanki samanzi sibona ukuba iqondo lobushushu letanki lamanzi lisezantsi kunomgubasi, i-fan relay iyahlulwa kwaye i-fan motor iyeke ukusebenza.
Into enxulumene nokusebenza kwefeni liqondo lobushushu letanki, kwaye iqondo lobushushu letanki alinxulumananga ngokuthe ngqo nobushushu bamanzi enjini.
Isikhundla sokusebenza kunye nomgaqo we-fan yokupholisa imoto: inkqubo yokupholisa imoto ibandakanya iindidi ezimbini.
Ukupholisa ulwelo kunye nokupholisa umoya.Inkqubo yokupholisa yesithuthi esipholileyo solwelo sijikelezisa ulwelo ngemibhobho kunye nemijelo ekwinjini.Xa ulwelo luhamba kwi-injini eshushu, lufunxa ubushushu kwaye luyipholise injini.Emva kokuba ulwelo ludlule kwi-injini, luguqulwa lutshintshe ubushushu (okanye i-radiator), apho ubushushu obuvela kulwelo buchithwa emoyeni.Ukupholisa umoya Ezinye iimoto zangaphambili zazisebenzisa ubuchwepheshe bokupholisa umoya, kodwa iimoto zale mihla aziyisebenzisi le ndlela.Esikhundleni sokujikeleza ulwelo nge-injini, le ndlela yokupholisa isebenzisa amaphepha e-aluminiyam ancanyatheliswe kumphezulu weesilinda ze-injini ukuwapholisa.Iifeni ezinamandla zivuthela umoya kumaphepha e-aluminiyam, zikhupha ubushushu kumoya ongenanto, opholisa injini.Kuba uninzi lweemoto zisebenzisa ukupholisa ulwelo, iimoto zemibhobho zinemibhobho emininzi kwinkqubo yazo yokupholisa.
Emva kokuba impompo ihambise ulwelo kwibhloko ye-injini, ulwelo luqala ukuqukuqela kwiitshaneli ze-injini ezijikeleze isilinda.Emva koko ulwelo lubuyela kwi- thermostat ngentloko yesilinda ye-injini, apho ithi iphume enjinini.Ukuba i-thermostat icinyiwe, ulwelo luya kuqukuqela lubuyele ngqo kwimpompo ngemibhobho ejikeleze i-thermostat.Ukuba i-thermostat ivuliwe, ulwelo luya kuqala ukugeleza kwiradiyetha kwaye lubuyele kwimpompo.
Inkqubo yokufudumeza nayo inomjikelezo ohlukeneyo.Umjikelo uqala kwintloko yesilinda kwaye wondla ulwelo ngokusebenzisa imivumbo yesifudumezi ngaphambi kokuba ubuyele kumpompo.Kwiimoto ezinokuhanjiswa okuzenzekelayo, ngokuqhelekileyo kukho inkqubo yomjikelezo eyahlukileyo yokupholisa ioli yokuhambisa eyakhelwe kwiradiyetha.Ioli yokuhanjiswa impontshwa ngokugqithiswa ngomnye umtshintshi wobushushu kwiradiyetha.Ulwelo lunokusebenza kuluhlu olubanzi lweqondo lobushushu ukusuka kakuhle ngaphantsi kweqondo elingu-zero ukuya kutsho ngaphezulu kwama-38 ngokukaCelsius.
Ngoko ke, naluphi na ulwelo olusetyenziselwa ukupholisa injini kufuneka lube neqondo lokukhenkcela elisezantsi kakhulu, indawo yokubila ephezulu kakhulu, kwaye ikwazi ukufunxa uluhlu olubanzi lobushushu.Amanzi lolona lwelo lusebenzayo ukufunxa ubushushu, kodwa indawo yokukhenkceza yamanzi iphezulu kakhulu ukuhlangabezana neemeko zenjongo yeenjini zemoto.Ulwelo olusetyenziswa ziimoto ezininzi ngumxube wamanzi kunye ne-ethylene glycol (c2h6o2), ekwaziwa ngokuba sisipholisa.Ngokufaka i-ethylene glycol emanzini, indawo yokubilisa inokunyuswa kakhulu kwaye indawo yokukhenkceza iyancipha.
Ngalo lonke ixesha injini isebenza, impompo ijikeleza ulwelo.Ngokufana neempompo ze-centrifugal ezisetyenziswa kwiimoto, njengoko impompo ijikeleza, ipompoza ulwelo ngaphandle ngamandla e-centrifugal kwaye ihlala ifunxa phakathi.I-inlet yempompo ifumaneka kufuphi neziko ukwenzela ukuba ulwelo olubuya kwi-radiator lunokuqhagamshelana nee-blades zempompo.Iibhleyidi zempompo zithwala ulwelo ukuya ngaphandle kwempompo, apho lungena khona enjini.Ulwelo olusuka kwimpompo luqala ukuqukuqela kwibhloko ye-injini kunye nentloko, luze lungene kwiradiyetha, luze ekugqibeleni lubuyele kwimpompo.Ibhloko ye-injini ye-cylinder kunye nentloko inenani leendlela ezenziwe ngokusasaza okanye imveliso yomatshini ukuququzelela ukuhamba kwamanzi.
Ukuba ulwelo kule mibhobho luhamba kakuhle, kuphela ulwelo oludibene nombhobho luya kupholiswa ngokuthe ngqo.Ubushushu obudluliselwe kulwelo oluhamba ngombhobho ukuya kumbhobho kuxhomekeke kumahluko obushushu phakathi kombhobho kunye nolwelo oluchukumisa umbhobho.Ngoko ke, ukuba ulwelo oludibene nombhobho luphole ngokukhawuleza, ubushushu obugqithisiweyo buya kuba buncinci kakhulu.Lonke ulwelo olukumbhobho lunokusetyenziswa ngokufanelekileyo ngokudala isiphithiphithi kumbhobho, ukuxuba lonke ulwelo, nokugcina ulwelo ludibane nombhobho kumaqondo obushushu aphezulu ukuze lufunxe ubushushu obuninzi.
I-cooler yokuhambisa ifana kakhulu ne-radiator kwi-radiator, ngaphandle kokuba ioli ayitshintshi ukushisa kunye nomzimba womoya, kodwa kunye ne-antifreeze kwi-radiator.Isigqubuthelo setanki yoxinzelelo Isivalo setanki yoxinzelelo singanyusa indawo yokubila yesithinteli-mkhenkce ngama-25℃.
Umsebenzi ophambili we-thermostat kukufudumeza i-injini ngokukhawuleza kwaye ugcine ubushushu obungaguqukiyo.Oku kuphunyezwa ngokulungelelanisa ubungakanani bamanzi aqukuqelayo kwiradiyetha.Kumaqondo obushushu aphantsi, i-radiator yokuphuma iya kuvaleka ngokupheleleyo, nto leyo ethetha ukuba yonke i-antifreeze iya kujikeleza kwi-injini.Emva kokuba iqondo lokushisa le-antifreeze likhuphukela kwi-82-91 C, i-thermostat iya kuvulwa, eya kuvumela ulwelo ukuba luhambe kwi-radiator.Xa iqondo lobushushu le-antifreeze lifikelela kwi-93-103℃, isilawuli sobushushu siyakuhlala sivuliwe.
Ifeni yokupholisa iyafana ne-thermostat, ngoko ke kufuneka ihlengahlengiswe ukuze igcine i-injini ikwiqondo lobushushu elingaguqukiyo.Iimoto zokuqhuba ngamavili angaphambili zineefeni zombane kuba injini idla ngokuxhonywa ngokuthe tye, oko kuthetha ukuba ukuphuma kwe-injini kujonge kwicala lemoto.
I-fan inokulungiswa ngokutshintsha kwe-thermostatic okanye ikhompyutha ye-injini.Xa iqondo lokushisa liphakama ngaphezu kwendawo emiselweyo, aba balandeli baya kuvulwa.Xa ubushushu buhla ngaphantsi kwexabiso elimiselweyo, aba balandeli baya kuvalwa.Ifeni yokupholisa Iimoto eziqhuba ngasemva ezineenjini zobude zihlala zixhotyiswe ngeefeni zokupholisa eziqhutywa yi-injini.Aba balandeli bane-thermostatic viscous clutches.I-clutch ibekwe kumbindi wefeni, ijikelezwe ngumoya ophuma kwiradiyetha.Le clutch ye-viscous ngamanye amaxesha ifana ne-viscous coupler yemoto eqhutywa ngamavili onke.Xa imoto ishushu, vula zonke iiWindows kwaye uqhube i-heater xa i-fan isebenza ngesantya esiphezulu.Oku kungenxa yokuba inkqubo yokufudumeza ngokwenene yinkqubo yokupholisa yesibini, enokuthi ibonise imeko yenkqubo yokupholisa ephambili kwimoto.
Isixokelelwano sokufudumala Imivumbo yesifudumezi ebekwe kwideshibhodi yemoto eneneni iyiradiyetha encinci.Umshicileli we-heater uthumela umoya ongenanto ngokusebenzisa i-heater bellows kunye negumbi labahambi bemoto.Izifutho zokufudumeza ziyafana neeradiyetha ezincinci.Izifutho zesifudumezi zifunxa isithinteli-mfuduko esishushu esisuka kwintloko yesilinda size siphinde siyibuyisele kwimpompo ukuze isifudumezi sisebenze xa ithermostat ivuliwe okanye icinyiwe.
