Yini inzwa yokucindezela emoyeni wezimoto
Inzwa yengcindezi yomoya yezimoto yezimoto iyingxenye esemqoka yohlelo lweqandi. Umsebenzi wayo oyinhloko ukuqapha ingcindezi esiqandisi epayipi elimoyeni ngesikhathi sangempela, uqinisekise ukusebenza okuphephile kwe-compressor, futhi usebenze nezinye izakhi zokulawula ngokunembile isiqalo nesicindezelayo. Imvamisa ifakwe endaweni enomoya wokucindezela wengcindezelo e-Injini futhi idlulisela idatha yokucindezela eqoqiwe kwi-ECU ECU noma iyunithi yokulawula yomoya ekhethekile. Lapho i-ECU ithola isinali esijwayelekile sokucindezela, iqala i-compressor kanye ne-fan epholile; Uma isinali yokucindezela engajwayelekile sitholwa, kuthathwa izinyathelo ezisheshayo ukuvimba imishini yokufaka umoya njengama-compressors kusuka ekuqaleni, ngaleyo ndlela ukuvikela lonke uhlelo lwefriji.
I-Air Consioning Pressure Sensor ivame ukwamukela ukwakhiwa kwesistimu emithathu, imodi yayo yokulawula ifaka isiginali ye-analog, i-LIN ibhasi kanye nomsebenzi wokulawula ukuqondisa izinhlobo ezintathu. Ukukala inzwa yengcindezi ye-air conditioner, sebenzisa i-multimeter ukukala ikhebula lamandla, ikhebula lomhlaba, nentambo yesiginali yenzwa. Ezimweni ezijwayelekile, ikhebula lamandla lingu-5v noma i-12v, ikhebula lomhlabathi lingu-0V, kanti ikhebula lesiginali liguquguquka ebangeni le-0.5v kuya ku-4.5v noma i-1V ku-5V. Uma inani elilinganisiwe lihluke kakhulu kwinani elijwayelekile, kungasho ukuthi inzwa ilimele noma kukhona ukuxhumana okubonakalayo ku-harness.
Inzwa yomoya yomoya yokucindezela idlala indima ebalulekile ezinhlelweni zokuqapha zemoto. Uma inzwa yehluleka, kungahle kungaholeli ngaphandle komphumela wokupholisa emotweni, i-compressor ayikwazi ukusebenza, noma ukuqala njalo nokumisa izinkinga. Ngakho-ke, ukuhlolwa okujwayelekile kanye nokugcinwa kwenzwa yomoya yomoya kuyisilinganiso esibalulekile sokuqinisekisa ukusebenza okujwayelekile kohlelo lokufaka izimoto.
Umgomo wokusebenza we-air air air air spress sensor ususelwa ekulinganiseni ingcindezi, imvamisa equkethe ifilimu elincanyana kanye negridi yabaphikisi. Lapho ingcindezi ohlelweni lwezimoto zomoya ezishintsha khona, ingcindezi yemiphakathi elinganisiwe izodluliselwa kwifilimu enzwa. Ifilimu deforms ngaphansi kwesenzo sokucindezela, okuphumela ekushintsheni okuhambisanayo kwegridi yokumelana nefilimu. Lolu shintsho lokumelana lungatholwa futhi lufundwe yisitayela esixhumene nedeshibhodi noma olunye iyunithi lokulawula.
Ukusetshenziswa kwezinzwa zomoya wezimoto zomoya wezimoto ezinhlelweni zezimo ezimotweni zezimoto kufaka izinhlobo eziningi, uhlobo ngalunye lunomsebenzi walo oqondile nendawo yokufaka. Isibonelo, i-voltage stanch ephezulu ifakiwe epayipini le-condenser Loclet ukuguqula ijubane lemoto ye-fan futhi liqinisekise ukuthi ingcindezi ye-condenser igcinwa ngaphakathi kwebanga eliphephile. Lapho ingcindezi yokuvumelanisa ingaphansi kune-1.51 MPA, fan igcina ukusebenza kwejubane eliphansi. Lapho ingcindezi idlula i-1.5 MPA, i-Fan isheshisa ngejubane eliphezulu. Ngaphezu kwalokho, i-switch switch yokushisa ephindwe kabili itholakala eduze kwe-condenser futhi ihlanganise ukushintshwa kwengcindezi ephezulu nge-injini yokushisa okupholile ukulawula ukusebenza kwemoto yemoto evumelanayo. Lapho izinga lokushisa elipholile liphakathi kuka-95 no-102 ° C, abalandeli bajikeleza ngejubane eliphansi; Lapho izinga lokushisa lidlula i-102 ° C, abalandeli basebenza ngejubane elikhulu.
Iqhaza lezinzwa zomoya wezimoto emoyeni ezimotweni ezimotweni emotweni yezimo zomoya ezimotweni ukuvikela uhlelo futhi kuthuthukise ukusebenza kahle. Bavimbela ingcindezi eyedlulele ukuthi ibangele ukulimala kwezakhi ngokubheka ushintsho lokucindezela ngaphakathi kohlelo. Isibonelo, lapho umfutho wengcindezi ephezulu yokucindezela ungaphansi kwe-0.2 MPA noma ngaphezulu kwe-3.2 MPA, i-compressor's electromagnetic clutch ixhunyiwe ukuvikela uhlelo; I-clutch ihlala ihlanganyele phakathi kuka-0.22 no-3.2 MPA. Ngaphezu kwalokho, ukushintshwa kwamazinga okushisa kwangaphandle kunqamula i-electromagnetic clutch lapho amazinga okushisa engaphansi kuka-5 ° C, ukuvimbela i-compressor yomoya kusuka ekusebenzeni okuphansi.
