Indima yesistimu yokupholisa injini

Isistimu yokupholisa yakhelwe ukuvimbela injini ekushiseni ngokweqile nasekushiseni ngokweqile.Ukushisa ngokweqile kanye nokubanda kancane kuzodala imvume evamile yezingxenye ezihambayo zenjini ukuba zibhujiswe, isimo sokuthambisa siwohloke, kusheshise ukuguga kwenjini.Amazinga okushisa enjini aphezulu kakhulu angabangela ukubilisa okupholisayo, kwehlise kakhulu ukusebenza kahle kokudlulisa ukushisa, ukusha ngaphambi kwesikhathi kwengxube, kanye nokushayisa kwenjini okungenzeka ekugcineni konakalise izingxenye zenjini ezifana nekhanda lesilinda, amavalvu namapiston.Izinga lokushisa lenjini liphansi kakhulu, kuzoholela ekushiseni okunganele, ukwanda kokusetshenziswa kukaphethiloli, impilo yesevisi yenjini iyancipha.

Ukwakheka kwesakhiwo sesistimu yokupholisa injini

1. I-radiator

I-radiator ngokuvamile ifakwa ngaphambili kwemoto, lapho imoto isebenza, umoya oshisayo ozayo ozayo ugeleza njalo kurediyetha, ususa ukushisa kwesipholile, ukuze uqinisekise umphumela omuhle wokukhipha ukushisa.

Irediyetha iyisishintshi sokushisa esihlukanisa isipholile sezinga lokushisa eliphezulu esigeleza siphuma ebhantshini lamanzi lekhanda lesilinda sibe imifudlana eminingi ukuze kwandiswe indawo yokupholisa nokusheshisa ukupholisa kwayo. i-radiator core.Isipholisi sezinga eliphezulu lokushisa sidlulisa ukushisa ngomoya ophansi wezinga lokushisa ukuze kuzuzwe ukushintshana kokushisa.Ukuze uthole umphumela omuhle wokukhipha ukushisa, irediyetha isebenza nefeni yokupholisa.Ngemva kokuba isipholile sidlule kurediyetha, izinga lokushisa laso lingancishiswa ngo-10 ~ 15℃.

2, ithangi lamanzi lokunwetshwa

Ithangi lokunweba ngokuvamile lenziwa ngepulasitiki ekhanyayo ukuze kube lula ukubhekwa kwezinga layo langaphakathi lokupholisa.Umsebenzi oyinhloko wethangi lokunweba ukunikeza isikhala ukuze isipholile sikhule futhi sinciphe, kanye nendawo yokukhipha umoya emaphakathi yesistimu yokupholisa, ngakho-ke ifakwe endaweni ephakeme kancane kunezinye iziteshi zokupholisa.

3. Ukupholisa fan

Amafeni okupholisa ngokuvamile afakwa ngemuva kwe-radiator.Lapho isiphephetha-moya esipholile sizungeza, umoya umuncwa kurediyetha ukuze kuthuthukiswe amandla okukhipha ukushisa kwerediyetha futhi kusheshiswe isivinini sokupholisa sesipholisa.

Esigabeni sokuqala sokusebenza kwenjini noma izinga lokushisa eliphansi, ifeni yokupholisa kagesi ayisebenzi.Uma inzwa yezinga lokushisa elipholile ithola ukuthi izinga lokushisa elipholile lidlula inani elithile, i-ECM ilawula ukusebenza kwenjini yefeni.

Umsebenzi nokwakheka kwesistimu yokupholisa injini

4, i-thermostat

I-thermostat iyivalvu elawula indlela yokugeleza kwesipholile.Ivula noma ivale indlela yesipholile ukuya kurediyetha ngokuvumelana nezinga lokushisa lesipholile.Lapho injini iqalwa ngokubanda, izinga lokushisa lesipholisa liphansi, futhi i-thermostat izovala umgudu wesipholile esigelezela kurediyetha.Isipholile sizogeleza sibuyele ngqo kusilinda kanye nebhantshi lamanzi lekhanda lesilinda ngepompo lamanzi, ukuze isipholile sifudumale ngokushesha.Lapho izinga lokushisa elipholile likhuphukela enanini elithile, i-thermostat izovula ishaneli ukuze isipholile sigeleze siye kurediyetha, futhi isipholile sizogeleza sibuyele empompini ngemva kokupholiswa yi-radiator.

I-thermostat yezinjini eziningi itholakala kulayini we-cylinder head outlet.Leli lungiselelo linenzuzo yesakhiwo esilula.Kwezinye izinjini, i-thermostat ifakwa endaweni yokungena amanzi yepompo.Lo mklamo uvimbela izinga lokushisa elipholile elikusilinda lenjini ukuba lingawi kakhulu, ngaleyo ndlela kuncishiswe ukushintsha kwengcindezi enjinini futhi kugwenywe ukulimala kwenjini.

5, iphampu yamanzi

Injini yezimoto ngokuvamile isebenzisa iphampu yamanzi eyi-centrifugal, enesakhiwo esilula, usayizi omncane, ukufuduka okukhulu nokusebenza okuthembekile.Iphampu yamanzi eyi-centrifugal iqukethe igobolondo ne-impeller ene-coolant inlet namashaneli okuphuma.Ama-axle e-blade asekelwa yi-bearings eyodwa noma ngaphezulu evaliwe engadingi ukuthambisa.Ukusetshenziswa kwama-bearings avaliwe kungavimbela ukuvuza kwamafutha kanye nokungcola nokungena kwamanzi.Igobolondo lepompo lifakwe ku-injini ye-cylinder block, i-impeller yepompo igxiliwe ku-shaft yepompo, futhi indawo yepompo ixhunywe nomkhono wamanzi we-cylinder block.Umsebenzi wepompo uwukucindezela isipholile futhi uqinisekise ukuthi sizungeza ohlelweni lokupholisa.

6. Ithangi lamanzi anomoya ofudumele

Izimoto eziningi zinesistimu yokushisisa ehlinzeka umthombo wokushisa ngesibandisi senjini.Isistimu yomoya ofudumele inomgogodla we-heater, obizwa nangokuthi ithangi lamanzi omoya ofudumele, elakhiwe ngamapayipi amanzi nezingcezu zerediyetha, futhi zombili iziphetho zixhunywe ngokulandelana kwesistimu yokupholisa kanye nendawo yokungena.Isipholile senjini esisezingeni eliphezulu singena ethangini lomoya ofudumele, sishisise umoya odlula ethangini lomoya ofudumele, bese sibuyela esimisweni sokupholisa senjini.

7. Ukupholisa

Imoto izohamba ngezimo zezulu ezehlukene, imvamisa idinga ukuthi imoto emazingeni okushisa -40~40℃ ingasebenza ngokujwayelekile, ngakho isibandisi senjini kumele sibe nendawo ephansi yokuqandisa kanye nendawo yokubilisa ephezulu.

Isipholile siyingxube yamanzi athambile, i-antifreeze kanye nenani elincane lezithasiselo.Amanzi athambile awaqukethe (noma aqukethe inani elincane) i-calcium encibilikayo ne-magnesium compounds, engavimbela ngempumelelo ukukala futhi iqinisekise umphumela wokupholisa.I-Antifreeze ayikwazi nje ukuvimbela isibandisi ukuthi singaqhwa ngesikhathi esibandayo, gwema irediyetha, i-cylinder block, isilinda esivuvukalayo sekhanda, kodwa futhi singathuthukisa ngokufanelekile indawo yokubilisa yesipholile, siqinisekise umphumela wokupholisa.I-antifreeze evame ukusetshenziswa kakhulu i-ethylene glycol, uketshezi olungenambala, olusobala, olumnandi kancane, olune-hygroscopic, olune-viscous oluncibilika ngamanzi kunoma iyiphi ingxenye.I-coolant ibuye yengezwe nge-rust inhibitor, i-foam inhibitor, i-bactericidal fungicide, i-pH regulator, i-colorant njalonjalo.
