Isistimu yokupholisa injini ingenye yezinhlelo eziyisithupha ezinkulu zenjini.Umsebenzi wayo ukuhlakaza ingxenye yokushisa emuncwa izingxenye ezishisayo ngesikhathi ukuze kuqinisekiswe ukuthi injini isebenza ezingeni lokushisa elifanele kakhulu.
Izingxenye zesistimu yokupholisa
Kuwo wonke uhlelo lokupholisa, indawo yokupholisa iyapholisa, futhi izingxenye eziyinhloko yi-thermostat, iphampu yamanzi, ibhande lepompo lamanzi, irediyetha, ifeni epholile, inzwa yokushisa kwamanzi, ithangi lokugcina uketshezi, nedivayisi yokushisisa (efana nerediyetha).
1) Ukupholisa
I-Coolant, eyaziwa nangokuthi i-antifreeze, iwuketshezi olwakhiwe izithasiselo ezivimbela ukubanda, izithasiselo zokuvimbela ukugqwala kwensimbi, namanzi.Idinga ukuba ne-anti-freeze, i-anti-corrosion, i-thermal conductivity kanye nezakhiwo ezingaboli.Namuhla, i-ethylene glycol ivame ukusetshenziswa njengengxenye eyinhloko, futhi i-antifreeze enezithako zokulwa nokubola kanye namanzi yengezwa.Amanzi okupholisa kungcono amanzi athambile, angavimbela ibhantshi lamanzi lenjini ukuthi lingakhiqizi isikali, esizovimba ukudluliswa kokushisa futhi kwenze injini ishise kakhulu.Ukwengeza isinqandi-qhwa emanzini futhi kuphakamisa indawo yokubilisa yesipholile, esinomphumela owengeziwe wokuvimbela ukubilisa ngaphambi kwesikhathi kwesipholile.Ngaphezu kwalokho, i-coolant iqukethe ne-foam inhibitors, engavimbela umoya ekukhiqizeni igwebu ngaphansi kokuyaluza kwe-impeller yepompo yamanzi futhi ivimbele udonga lwejakhethi yamanzi ekuqedeni ukushisa.
2) I-Thermostat
Kusukela ekwethulweni komjikelezo wokupholisa, kungabonakala ukuthi i-thermostat inquma ukuya "umjikelezo obandayo" noma "umjikelezo ovamile".I-thermostat ivula ngemva kuka-80°C, futhi umkhawulo wokuvula ungo-95°C.Ukungakwazi ukuvala i-thermostat kuzobeka umjikelezo "kumjikelezo ovamile" kusukela ekuqaleni, okuzoholela ekutheni injini ingafinyeleli noma ifinyelele izinga lokushisa elivamile ngokushesha ngangokunokwenzeka.I-thermostat ayikwazi ukuvulwa noma ukuvuleka akuguquki, okuzovimbela isipholile ukuba sijikeleze kurediyetha, kubangele izinga lokushisa libe phezulu kakhulu, noma libe ngokwejwayelekile uma liphezulu.Uma ukushisa ngokweqile kwenzeka ngenxa yokuthi i-thermostat ayikwazi ukuvulwa, izinga lokushisa nokucindezela kwamapayipi amanzi aphezulu naphansi we-radiator kuzohluka.
3) Iphampu yamanzi
Umsebenzi wephampu yamanzi uwukucindezela isipholile ukuqinisekisa ukuthi siyazungeza ohlelweni lokupholisa.Ukwehluleka kwepompo yamanzi kuvame ukubangelwa ukulimala kophawu lwamanzi okubangela ukuvuza, futhi ukwehluleka kwe-bearing kubangela ukujikeleza okungavamile noma umsindo.Lapho injini ishisa kakhulu, into yokuqala okufanele uyiqaphele yibhande lepompo lamanzi, hlola ukuthi ibhande liphukile noma likhululekile.
4) I-radiator
Lapho injini isebenza, isipholile sigeleza kumongo werediyetha, umoya udlulela ngaphandle kwenkambo yerediyetha, futhi okokupholisa okushisayo kubanda ngenxa yokukhishwa kokushisa emoyeni.Kukhona futhi ingxenye encane ebalulekile ku-radiator, i-cap ye-radiator, enganakwa kalula.Njengoba izinga lokushisa lishintsha, okokupholisa "kuzonwebeka futhi kunciphe", futhi ukucindezela kwangaphakathi kwe-radiator kuyanda ngenxa yokwanda kwesipholisa.Lapho ingcindezi yangaphakathi ifinyelela ezingeni elithile, ikhava yerediyetha iyavuleka bese isipholisa sigelezela ethangini lokugcina;yehlisa bese into epholile igeleze ibuyele kurediyetha.Uma ukupholisa ku-accumulator kunganciphi, kodwa izinga le-radiator fluid liyancipha, khona-ke i-cap ye-radiator ayisebenzi!
5) Ukupholisa fan
Ngesikhathi sokushayela okuvamile, ukugeleza komoya okunesivinini esikhulu kwanele ukuqeda ukushisa, futhi ifeni ngokuvamile ayisebenzi ngalesi sikhathi;kodwa lapho isebenza ngesivinini esinensayo futhi endaweni, ifeni ingase ijikeleze ukuze isize irediyetha ikhiphe ukushisa.Ukuqala kwefeni kulawulwa inzwa yezinga lokushisa kwamanzi.
6) Inzwa yokushisa kwamanzi
Inzwa yezinga lokushisa kwamanzi empeleni iwukushintsha kwezinga lokushisa.Uma izinga lokushisa lamanzi elingenisa injini lingaphezu kuka-90°C, inzwa yezinga lokushisa lamanzi izoxhumeka kumjikelezo wabalandeli.Uma umjikelezo uvamile futhi ifeni ingajikijeli lapho izinga lokushisa likhuphuka, inzwa yezinga lokushisa lamanzi nefeni ngokwayo kudingeka ihlolwe.
7) Ithangi lokugcina uketshezi
Umsebenzi wethangi lokugcina uketshezi ukwengezela into epholile kanye ne-buffer kushintsho "lwe-thermal and contraction contraction", ngakho ungagcwalisi ngokweqile uketshezi.Uma ithangi lokugcina uketshezi lingenalutho ngokuphelele, awukwazi nje ukwengeza uketshezi ku-tank, udinga ukuvula i-cap ye-radiator ukuze uhlole izinga le-liquid bese wengeza i-coolant, ngaphandle kwalokho ithangi lokugcina uketshezi lizolahlekelwa umsebenzi walo.
8) Idivayisi yokushisa
Idivayisi yokushisisa emotweni ngokuvamile ayiyona inkinga.Kungabonakala esethulweni somjikelezo ukuthi lo mjikelezo awulawulwa yi-thermostat, ngakho-ke vula i-heater uma imoto ibanda, lo mjikelezo uzoba nomthelela obambezeleke kancane ekukhuphukeni kwezinga lokushisa kwenjini, kodwa umphumela empeleni encane, ngakho-ke asikho isidingo sokushisa injini.Yiqhwa.Kungenxa yezimpawu zalo mjikelezo ukuthi uma kunesimo esiphuthumayo lapho injini ishisa ngokweqile, ukuvula amafasitela nokuvula ukushisa kuze kube sezingeni eliphezulu kuzosiza ukupholisa injini ngezinga elithile.
