Uyini umsebenzi wepulaki yesenzwa yokushisa kwamanzi emotweni
Inzwa yokushisa kwamanzi emotweni (inzwa yokushisa kwamanzi) idlala indima ebalulekile emotweni, izindima eziyinhloko zifaka okulandelayo:
Ukutholwa kwezinga lokushisa le-Cooler: Ipulaki yesensa yokushisa kwamanzi inesibopho sokulinganisa izinga lokushisa le-cooler ngesikhathi sangempela, okubalulekile enkambisweni yokufudumeza ngesikhathi sokuqala kokubanda. Iqapha izinguquko zokushisa ukuze ilawule isivinini sefeni uma kudingeka futhi ithonye ngisho nokusetha isivinini sokungenzi lutho ukuze kusebenze kahle kakhulu kanye nokusebenza kahle kukaphethiloli.
Ukulungiswa kokufakwa kukaphethiloli: Ngokuthola izinga lokushisa le-coolant, ipulaki yesensa yokushisa kwamanzi inikeza isignali yokulungisa uhlelo lokufakwa kukaphethiloli ukuqinisekisa ukufakwa kukaphethiloli okunembile, ukugwema izinga lokushisa lokushisa eliphezulu kakhulu noma eliphansi kakhulu, ngaleyo ndlela kuvikelwe injini futhi kuthuthukiswe ukonga kukaphethiloli.
Bonisa ulwazi lokushisa kwamanzi: Inikeza ukufundwa kwangempela kwesilinganiso sokushisa kwamanzi semoto ukuze umshayeli akwazi ukuqonda isimo sokusebenza kwenjini futhi athathe isinyathelo ngesikhathi ukuze alondoloze ukusebenza okuhle kakhulu.
Ukulungiswa kwesikhathi sokusha: isignali yokushisa okupholile etholwe yipulaki yesenzwa yokushisa kwamanzi izophinde isetshenziswe ukulungisa isikhathi sokusha ukuqinisekisa isimo esingcono kakhulu sokusebenza kwenjini emazingeni okushisa ahlukene.
Umgomo wokusebenza wepulaki yokuzwa izinga lokushisa kwamanzi usekelwe ezimpahleni zayo zangaphakathi ze-thermistor. Inani lokumelana le-thermistor liyashintsha ngokushisa, futhi ipulaki yesensa yokushisa kwamanzi iguqula lolu shintsho lube isignali kagesi bese iyithumela kuyunithi yokulawula kagesi (ECU). I-ECU ilungisa isikhathi sokufaka, isikhathi sokusha kanye nokulawula ifeni ngokuya ngesignali etholakele, ngaleyo ndlela iqaphela ukulawula okunembile kwenjini .
Izinhlobo ezahlukene zamapulagi okuzwa ukushisa kwamanzi afaka phakathi umugqa owodwa, uthayela ababili, uthayela abathathu kanye nothayela abane. Ahlukahluka ngomklamo kanye nomsebenzi futhi avame ukufakwa ezindaweni ezibalulekile zesistimu yokupholisa, njengaseduze nekhanda lesilinda, ibhlokhi kanye ne-thermostat .
Uma ipulaki yesenzwa yokushisa kwamanzi emotweni yonakele, kuzovela izimpawu ezilandelayo eziyinhloko:
Isexwayiso sephaneli yezinsimbi: Uma ipulaki yesenzwa yokushisa kwamanzi inephutha, inkomba efanele kuphaneli yezinsimbi ingacwayiza noma iqhubeke nokukhanya njengesignali yesexwayiso sesistimu.
Ukufundwa kwezinga lokushisa okungajwayelekile : Izinga lokushisa eliboniswe ku-thermometer alihambisani nezinga lokushisa langempela. Ngenxa yalokho, inkomba ye-thermometer ingase ingahambi noma ingakhombisi endaweni yokushisa ephezulu kakhulu.
Ubunzima bokuqala okubandayo : Ngesikhathi sokuqala okubandayo, i-ECU ayikwazi ukunikeza ulwazi olufanele lokuhlushwa kwengxube ngenxa yokuthi inzwa ibika kabi isimo sokuqala okushisayo, okwenza ukuqala okubandayo kube nzima.
Ukusetshenziswa kukaphethiloli okwandisiwe kanye nesivinini sokungaqhubeki kahle: Izinzwa ezingalungile zingathinta ukulawula kwe-ECU kokujova uphethiloli kanye nesikhathi sokusha, okuholela ekusetshenzisweni kukaphethiloli okwandisiwe kanye nesivinini sokungaqhubeki kahle esingaguquki.
Ukusebenza kwesivinini kwehla : ngisho noma i-throttle igcwele, ijubane lenjini alikwazi ukwanda, okubonisa ukuntuleka kwamandla okusobala.
Umgomo wokusebenza kanye nokubaluleka kwepulaki yesenzwa yokushisa kwamanzi: ngokuqapha izinga lokushisa lamanzi okupholisa injini, ulwazi lokushisa luguqulwa lube isignali kagesi kanye nokukhipha kuyunithi yokulawula kagesi, ukuze kulawulwe ngokunembile inani lokufakwa kukaphethiloli, isikhathi sokusha kanye nezinye izilinganiso ezibalulekile. Kuphinde kuthinte ukusebenza kwezingxenye ezifana ne-valve yokulawula engasebenzi ukuqinisekisa ukusebenza okuvamile kwenjini.
Indlela yokuhlola nokufaka esikhundleni: Sebenzisa i-multimeter ukuhlola inzwa yokushisa kwamanzi. Shisisa inzwa bese ubona ushintsho lokumelana ukuze ubone ukuthi ilungile noma imbi. Ngaphezu kwalokho, ukusebenzisa ithuluzi lokuxilonga iphutha ukuhlola ukuthi ikhona yini ikhodi yephutha esimweni sokubanda nakho kuyindlela ephumelelayo yokuthola. Uma iphutha selitholakele, kumele lishintshwe ngesikhathi ukuqinisekisa ukusebenza okuvamile kwenjini.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
