Ukuxilongwa kwephutha nokugcinwa kwesistimu yokupholisa injini yemoto (一)
2021-08-05
Uhlelo lokupholisa luyingxenye ebalulekile yenjini. Ngokolwazi olufanele, cishe u-50% wamaphutha ezimoto avela enjinini, futhi cishe u-50% wamaphutha enjini abangelwa amaphutha esistimu yokupholisa. Kungabonakala ukuthi uhlelo lokupholisa ludlala indima ebalulekile ekuthembekeni kwemoto. Isistimu yokupholisa ngeke ibe nomthelela omkhulu ekuthembekeni kwenjini kuphela, kodwa futhi isici esibalulekile esithinta amandla nomnotho wenjini. Umsebenzi wayo ukuqinisekisa ukuthi injini ingasebenza ngendlela evamile futhi enokwethenjelwa emazingeni okushisa afaneleka kakhulu ngaphansi kwanoma yisiphi isimo somthwalo nendawo yokusebenza.
Iphutha lemoto: izinga lokushisa elingavamile kanye nokushisa ngokweqile ngesikhathi sokusebenza kwemoto.
Ukutholwa kwamaphutha: ukwenza injini isebenze ngendlela enokwethenjelwa futhi iqine, isistimu yokupholisa kufanele yenze injini isebenze ngaphakathi kwebanga lokushisa elifaneleka kakhulu ngaphansi kwanoma yisiphi isimo sokusebenza senjini kanye nanoma iliphi izinga lokushisa elingaba khona lendawo. Qinisekisa ukuthi injini isebenza ngaphakathi kwebanga lokushisa elifanele.
Ukutholwa kwephutha 1: iphutha le-thermostat
(1) Hlola izinga lokushisa kwamanzi apholisayo. Bheka igeji yokushisa kwamanzi yephaneli yensimbi. Uma izinga lokushisa lamanzi likhuphuka kancane, libonisa ukuthi i-thermostat ayisebenzi ngokujwayelekile. Ngemva kokuhlola, isivinini sokukhuphuka kwezinga lokushisa lamanzi sivamile.
(2) Hlola izinga lokushisa lamanzi erediyetha, faka inzwa yethemometha yedijithali ethangini lamanzi, ulinganise izinga lokushisa legumbi lamanzi elingaphezulu kanye nokufundwa kwethemometha yamanzi (izinga lokushisa lebhantshi lenjini) bese uqhathanisa nazo. Ngaphambi kokuba izinga lokushisa lamanzi likhuphukele ku-68 ~ 72 ℃, noma ngisho nangemva kokuba injini iqalile, izinga lokushisa lamanzi le-radiator liyakhuphuka kanye nezinga lokushisa lamanzi lebhantshi lamanzi, okubonisa ukuthi i-thermostat impofu. Ayikho into enjalo ngemva kokuhlolwa.
Umphumela wokuhlola: i-thermostat isebenza ngokujwayelekile.
Ukutholwa kwephutha 2: ukushisa kwenjini okubangelwa amanzi okupholisa anganele.
ukusetshenziswa ngesikhathi sokusebenza. Ukuhlaziya nokuxilongwa:
(1) Hlola ukuthi umthamo wamanzi okupholisa wanele yini. Uma irediyetha iyinhle, susa ithange lamanzi enjini bese uhlola isikali esibekwe epayipini lamanzi. Ukuqoqwa akukona okungathí sina, kodwa kunesilinganiso esithile.
(2) Nweba isiqephu sokhuni esihlanzekile emgodini wokukhipha amanzi, futhi akukho mkhondo wamanzi emgqeni wokhuni obonisa ukuthi iphampu yamanzi ayivuzi.
(3) Hlola ukuthi akukho yini ukuvuza kwamanzi ngaphakathi kwesistimu yokupholisa. Akhiphe i-dipstick yamafutha. Uma kungekho manzi emafutheni enjini, susa ukugqashuka nokuvuza kwamanzi odongeni lwegumbi le-valve noma odongeni lwangaphakathi lomgudu wokungenisa umoya. Hlola ukuthi i-valve yokukhipha umoya yesivalo serediyetha iyehluleka yini. Uma amanzi okupholisa kulula ukuphuma emanzini okungena emanzini, kubonisa ukuthi i-valve yokukhipha i-cap ye-radiator ihluleka. Hlola ukuthi ayikho yini into engenhla futhi uqede ukuthi kungenzeka ukwehluleka kwe-valve yokukhipha umoya.
Imiphumela yokuhlolwa: Ukufakwa kwesikali sethangi lamanzi kungase kubangele amanzi anganele okupholisa.
Ukutholwa kwephutha 3: ukuchithwa kokushisa okunganele okubangelwa amanye amaphutha erediyetha. Cabangela amaphutha abangelwa amanye ama-radiator. Ukuhlaziya nokuxilongwa:
(1) Okokuqala hlola ukuthi isivalo sivuliwe noma sivaliwe. Uma ingavaliwe, ukuvuleka kwanele.
(2) Hlola ukulungiswa kwe-fan blade kanye nokuqina kwebhande. Ibhande lefeni lizungeza ngokujwayelekile. Hlola ivolumu yomoya wefeni. Indlela yokufaka iphepha elincanyana phambi kwe-radiator lapho injini isebenza, futhi iphepha lidonswa ngokuqinile, okubonisa ukuthi umthamo womoya wanele. Ukuqondiswa kwe-fan blade akufanele kuhlehliswe, ngaphandle kwalokho i-engeli ye-fan blade izolungiswa, futhi ikhanda le-blade kufanele ligotshwe kahle ukuze kuncishiswe i-eddy current. I-fan ijwayelekile.
(3) Thinta irediyetha nezinga lokushisa lenjini. Izinga lokushisa lerediyetha kanye nezinga lokushisa lenjini kujwayelekile, okubonisa ukuthi ukujikeleza kwamanzi okupholisa kuhle. Hlola ukuthi ipayipi le-radiator alimuncwanga futhi alicindezelwe yini, futhi imbobo yangaphakathi ayicindezelwanga futhi ayivalekile. Ipayipi elikhipha amanzi lisesimweni esihle. Khipha ipayipi lokungena lamanzi le-radiator bese uqala injini. Ngalesi sikhathi, amanzi okupholisa kufanele akhishwe ngamandla. Ukuhluleka ukukhipha amanzi kubonisa ukuthi iphampu yamanzi inephutha. Hlola ukuthi izinga lokushisa le-radiator nazo zonke izingxenye zenjini azilingani, futhi amakhaza nokushisa kwe-radiator akulingani, okubonisa ukuthi ipayipi lamanzi livaliwe noma kunenkinga nge-radiator.
Imiphumela yokuhlolwa: iphampu yamanzi inephutha, ipayipi lamanzi livalekile noma irediyetha inephutha.
