Isikhundla Sokusebenza kanye Nemigomo Yezimoto Zokupholisa Izimoto
1. Lapho inzwa yokushisa yethangi (empeleni i-valve yokulawula izinga lokushisa, hhayi i-water gauge lokushisa sensor) ibona ukuthi izinga lokushisa lethangi lidlula umkhawulo (iningi lama-degrees angu-95;
2. Umjikelezo wabalandeli uxhumeke ngokudluliselwa kwabalandeli, kanye nemoto yabalandelwa.
3. Lapho inzwa yokushisa yamathangi amanzi ethola ukuthi izinga lokushisa lamathangi lamanzi liphansi kunombundwondi, ihala okudluliselwe ku-fan
Isici esihlobene nokusebenza kwabalandeli yindlela yokushisa yamathangi, futhi izinga lokushisa lethangi alihlobene ngqo nokushisa kwamanzi enjini.
Isikhundla esisebenzayo kanye nomgomo we-Automobile Looding Fan: Uhlelo lokupholisa izimoto luhlanganisa izinhlobo ezimbili.
Ukupholisa uketshezi nokupholisa komoya. Uhlelo olupholile lwemoto epholile eluketshezi lujikeleza uketshezi ngamapayipi neziteshi enjini. Lapho uketshezi lugeleza ngenjini eshisayo, imunca ukushisa bese ipholisa injini. Ngemuva kokuthi uketshezi seludlulile enjini, luphambukiswa ku-Exchanger Exchanger (noma i-radiator), lapho ukushisa okuvela khona ku-liquid kuhlakazeke emoyeni. Ukupholisa umoya ezinye izimoto zokuqala ezisetshenzisiwe ubuchwepheshe bokupholisa umoya, kepha izimoto zanamuhla azisebenzi kahle le ndlela. Esikhundleni sokujikeleza koketshezi ngenjini, le ndlela yokupholisa isebenzisa amashidi we-aluminium anamathele ebusweni bama-cylinders enjini ukuze abaphoxe. Abalandeli abanamandla bavuza umoya emashidini e-aluminium, ukuqeda ukushisa emoyeni ongenalutho, okupholisa injini. Ngoba izimoto eziningi zisebenzisa ukupholisa uketshezi, izimoto ze-ductwork zinamapayipi amaningi ohlelweni lwazo lokupholisa.
Ngemuva kokuthi ipompo ilethe uketshezi ebhlokini lenjini, uketshezi luqala ukugeleza eziteshini zenjini ezungeze isilinda. Uketshezi bese lubuyela e-thermostat ngekhanda lesilinda senjini, lapho liphuma liphuma enjini. Uma i-thermostat icishiwe, uketshezi luzogobhoza ngqo empompini ngamapayipi azungeze i-thermostat. Uma i-thermostat ivuliwe, uketshezi luzoqala ukugeleza ku-radiator bese ubuyela ephampu.
Uhlelo lokushisa lunomjikelezo ohlukile. Umjikelezo uqala ekhanda lesilinda bese uveza uketshezi ngokusebenzisa ama-bellows we-heater ngaphambi kokubuyela ephampu. Ezimotweni ezihambisa ngokuzenzakalelayo, kuvame ukuba nenqubo ehlukile yomjikelezo ukupholisa uwoyela wokuhambisa owakhelwe kwi-radiator. Amafutha okuhambisa athenjwa ngokudluliselwa ngomunye umngcwabo wokushisa kwi-radiator. Uketshezi lungasebenza ebangeni lokushisa elibanzi kusuka ku-zero degrees Celsius ngenhla kwama-38 degrees Celsius.
Ngakho-ke, noma yini uketshezi olusetshenziselwa ukupholisa injini kufanele ibe nephuzu eliphansi kakhulu, iphuzu eliphakeme kakhulu, futhi likwazi ukudonsa ukushisa okuhlukahlukene. Amanzi kungenye yeziphuzo ezisebenza kahle kakhulu zokudonsa ukushisa, kepha iphuzu lamanzi liphezulu kakhulu ukuhlangabezana nezimo zenhloso zezinjini zezimoto. Uketshezi olusetshenziswa kakhulu izimoto luyingxube yamanzi ne-ethylene glycol (C2H6O2), eyaziwa nangokuthi opholile. Ngokungeza i-ethylene glycol emanzini, iphuzu elibilayo lingakhuphuka kakhulu futhi iphuzu leqhwa liyeke.
Njalo lapho injini isebenza, impompo ijikeleza uketshezi. Ifana namaphampu we-centrifugal asetshenziswe ezimotweni, njengoba amaphampu ahlele, aphawula uketshezi ngaphandle kwama-centrifugal Force futhi avele amunca phakathi phakathi. I-inlet yephampu itholakala eduze kwesikhungo ukuze uketshezi lubuya ku-radiator lungaxhumana nama-pump blades. Amabala epompo aphatha uketshezi ngaphandle kwephampu, lapho engena enjini. Uketshezi oluvela ephampu luqala ukugeleza ngebhulokhi lenjini kanye nekhanda, bese lingena kwi-radiator, bese ekugcineni libuyele ephampu. I-Cylinder Cylinder Block kanye nekhanda zineziteshi eziningi ezenziwe ngokusakaza noma ukukhiqizwa kwemishini ukwenza lula ukuhamba koketshezi.
Uma uketshezi kula mapayipi ligeleza kahle, kuphela uketshezi lokuxhumana nepayipi luzophola ngqo. Ukushisa okudluliselwe kusuka kuketshezi olugeleza ngepayipi kuya epayipi kuncike emazingeni okushisa phakathi kwepayipi noketshezi oluthinta ipayipi. Ngakho-ke, uma uketshezi lokuxhumana nepayipi lupholile ngokushesha, ukushisa okushintshiwe kuzoba mncane impela. Lonke uketshezi epayipini lungasetshenziswa kahle ngokwakha isiyaluyalu ngepayipi, ukuxuba lonke uketshezi, futhi ukugcina uketshezi luthintana nepayipi emazingeni okushisa aphezulu okuthola ukushisa okuphezulu.
Ukudluliselwa okupholile kufana kakhulu ne-radiator ku-radiator, ngaphandle kokuthi uwoyela akashintshana ngokushisa ngomzimba womoya, kodwa nge-antifreeze ku-radiator. Isembozo sethangi sethafa lesembozo sethafa lesembozo singangezelela iphuzu elibilayo le-antifreeze ngo-25 ℃.
Umsebenzi osemqoka we-thermostat ukushisa injini ngokushesha futhi ulondoloze izinga lokushisa njalo. Lokhu kutholakala ngokulungisa inani lamanzi ageleza nge-radiator. Emazingeni okushisa aphansi, okuphuma kwe-radiator kuzovinjwa ngokuphelele, okusho ukuthi yonke i-antifreeze izojikeleza ngenjini. Lapho izinga lokushisa le-antifreeze likhuphukela ku-82-91 c, i-thermostat izovulwa, ezovumela uketshezi ukuba lugeleze nge-radiator. Lapho izinga lokushisa le-antifreeze lifinyelela kuma-93-103 ℃, isilawuli sokushisa siyohlala sivulekile.
I-Fan epholile ifana ne-thermostat, ngakho-ke kufanele ilungiswe ukuze igcine injini yokushisa njalo. Izimoto ze-Front Wheel Drive zinabalandeli bakagesi ngoba injini ivame ukufakwa ngokuvundlile, okusho ukuthi umphumela wenjini ubhekene nohlangothi lwemoto.
Umlandeli angashintshwa ngokushintsha kwe-thermostatic noma ikhompyutha yenjini. Lapho amazinga okushisa enyuka ngenhla kwephuzu elisethiwe, laba abalandeli bazovulwa. Lapho amazinga okushisa ehla ngezansi kwenani elibekiwe, laba abalandeli bazocishwa. Izimoto ezipholile zokuvula amasondo ezi-wheel ezinezinjini ezinde zivame ukuhlome abalandeli be-injini abaqhutshwa yinjini. Lawa abalandeli banezinsimbi ezi-thermostatic viscous. I-Clutch itholakala enkabeni ye-fan, ezungezwe yi-airflow kusuka ku-radiator. Le cletch ethile ye-viscous kwesinye isikhathi ifana ne-punter e-viscous yemoto ye-wheel-wheel drive. Lapho imoto iwela phansi, vula wonke amafasitela bese uqhuba i-heater lapho fan esebenza ngejubane eligcwele. Lokhu kungenxa yokuthi uhlelo lokushisa empeleni luwuhlelo lokupholisa lwesibili, olungabonisa isimo sohlelo oluphambili lokupholisa emotweni.
I-heater system the heater bellows etholakala kudeshibhodi yemoto empeleni i-radiator encane. I-heater fan ithumela umoya ongenalutho ngokusebenzisa ama-bellows we-heater futhi ungene egumbini labagibeli emotweni. Ama-heater bellows ayafana nama-radiator amancane. I-heater ballows incela u-antifreer we-thermal kusuka ekhanda lesilinda bese ulifaka emuva ephampu ukuze i-heater ingavutha lapho kuvulwa i-thermostat.
