Umsebenzi we-sensor yoxinzelelo lweoyile yezithuthi
Umsebenzi ophambili we-sensor yoxinzelelo lweoyile yemoto kukubona uxinzelelo lweoyile kunye nokukhupha i-alamu xa uxinzelelo lunganelanga . I-sensor yoxinzelelo lweoyile ifakwe kumbhobho ophambili weoyile wenjini, ibona uxinzelelo lweoyile ngesixhobo sokulinganisa uxinzelelo, kwaye iguqula ezi zimpawu zoxinzelelo zibe ziimpawu zombane, ezithunyelwa kwisekethe yokucubungula isignali. Xa uxinzelelo lweoyile luhla ngaphantsi kwexabiso elikhuselekileyo elimiselweyo, isibane sesalathisi seoyile kwideshibhodi siya kukhanyisa ukuze sazise umqhubi ukuba .
Umgaqo wokusebenza
Kukho ukumelana okutyibilikayo ngaphakathi kwe-sensor yoxinzelelo lweoyile, kwaye utshintsho loxinzelelo lweoyile luya kutyhala i-potentiometer yokumelana nokutyibilika ukuba ihambe, ize itshintshe umbane we-gauge yoxinzelelo lweoyile, ukuze indawo yesikhombisi itshintshe. Kwangaxeshanye, isignali idluliselwa kwisalathisi soxinzelelo lweoyile ngomgca wesignali, kwaye umlinganiselo wombane odlula kwiikhoyili ezimbini kwisalathisi uyatshintshwa, ngaloo ndlela ubonisa uxinzelelo lweoyile lwemoto yokuqala . I-sensor idla ngokwenziwa yi-chip ye-sensor yoxinzelelo lwefilimu etyebileyo, isekethe yokucubungula isignali, i-housing, isixhobo sebhodi yesekethe esisisigxina kunye nee-leads ezimbini. Isekethe yokucubungula isignali ibandakanya isekethe yokubonelela ngombane, isekethe yokuhlawula isignali, isekethe yokulinganisa i-zeroing, isekethe yokukhulisa i-voltage, isekethe yokukhulisa i-current, isekethe yesihluzo kunye nesekethe ye-alamu .
Indawo yokufakela
I-sensor yoxinzelelo lweoyile idla ngokufakelwa kumbhobho ophambili weoyile wenjini, kwaye ngamanye amaxesha kwisihlalo sesihluzo seoyile. I-sensor yenziwe nge-contact, spring, diaphragm kunye ne-diaphragm. Xa kungekho xinzelelo lweoyile, i-spring ityhala i-diaphragm ukuze ivale i-contact; Xa uxinzelelo lufikelela kwixabiso elichaziweyo, i-diaphragm iyoyisa amandla e-spring ize iphule i-contact .
Iimpawu zokungaphumeleli kwe-oyile yemoto ziquka ezi zinto zilandelayo:
Xa i-sensor yoxinzelelo lweoyile yonakele, isalathisi soxinzelelo lweoyile siya kuqhubeka nokukhanya, nokuba uxinzelelo lweoyile lolona hlobo lunjani, nto leyo enokukhohlisa umqhubi ukuba akholelwe ukuba uxinzelelo lweoyile yenjini aluqhelekanga.
Ukuqina: Isibane kwisibane sokusilela kwenjini (esaziwa ngokuba yi-MIL okanye isibane sokujonga injini) sidla ngokuthetha ukuba kukho ingxaki efunyenwe yinkqubo yolawulo lwe-elektroniki yesithuthi. Ukusilela kwesivamvo soxinzelelo lweoyile kukwayenye yezizathu zokuba isibane sikhanye.
Umboniso wexabiso loxinzelelo lweoyile olungaqhelekanga: Kwimeko yokungasebenzi kwesithuthi, ukuba isenzi soxinzelelo lweoyile siyasilela, ixabiso loxinzelelo lweoyile eliboniswe kwideshibhodi lisenokuba lingaqhelekanga, njengelihlala liboniswa njengexabiso elizinzileyo (njenge-0.99) okanye uluhlu lokuguquguquka okungaqhelekanga.
Ikhowudi yempazamo i-P01CA iyavela: Xa inkqubo yokuxilonga imoto ifumanisa ukuba i-voltage yesensa yoxinzelelo lweoyile ayiphezulu kuluhlu oluqhelekileyo, ikhowudi yempazamo ehambelanayo, efana ne-P01CA, iya kurekhodwa kwaye iboniswe. Le khowudi yengxaki ibonisa ngokuthe ngqo ingxaki yesensa yoxinzelelo lweoyile.
Izizathu zokungasebenzi kakuhle kwe-sensor yoxinzelelo lweoyile zingabandakanya:
Isensor ngokwayo ayisemgangathweni ophantsi: iziphene zokwenza okanye ukwaluphala zikhokelela ekufumanekeni okungachanekanga okanye okonakeleyo.
Iingxaki zomgca: Isekethe emfutshane, isekethe evulekileyo okanye unxibelelwano olubi lunokuchaphazela ukuhanjiswa kwesignali.
Uxinzelelo lweoyile olungaqhelekanga: uxinzelelo lweoyile oluphezulu kakhulu okanye oluphantsi kakhulu luya kuzisa uxinzelelo olukhulu kwisensor.
Ungcoliseko lwenkunkuma: Inkunkuma evela ngaphakathi kwinjini ingavala okanye ingcolise izinzwa.
Indawo yokufakela engachanekanga : ukuphambuka kwendawo yokufakela kuya kuchaphazela ukuchaneka kokufunyanwa kwesensor.
ezinye iindawo zokungasebenzi kakuhle kwenjini: njengokuvaleka kwesihluzo, ioyile enganeleyo, njl.
Ukungazinzi kombane obonelelwa ngombane: ukutshintshatshintsha kombane kuya kuphazamisana nokusebenza okuqhelekileyo kwesensor.
I-internal short circuit ebangelwa kukungena kwe-sensor kulwelo okanye kwi-oyile.
Iindlela zokuchonga kunye nonyango:
Sebenzisa isixhobo sokuxilonga : funda ikhowudi yempazamo ngokudibanisa i-interface yokuxilonga ye-OBDII, umz. P0520 (impazamo yesekethe ye-sensor yoxinzelelo lweoyile).
Jonga uqhagamshelo lwentambo kwisensor: qinisekisa ukuba uqhagamshelo lwentambo alunamhlwa, aluphukile, okanye alukhululekanga.
Ukulinganisa i-voltage yokuphuma kwe-sensor: Sebenzisa i-multimeter ukulinganisa i-voltage yokuphuma kwe-sensor kwaye uqinisekise ukuba ikhupha i-voltage echanekileyo phantsi koxinzelelo olwahlukeneyo.
Uvavanyo lokuthelekisa i-mechanical pressure gauge : Susa i-electronic oil pressure sensor uze ufake i-mechanical pressure gauge ukuze kuvavanywe ukuthelekisa ukuze kuqinisekiswe ukuba i-sensor ayisebenzi.
Tshintsha inzwa : Ukuba inzwa iqinisekisiwe ukuba ayisebenzi, yitshintshe ngenzwa entsha ehambelana nemoto yokuqala.
