Isebenza ku-Ford fuel pressure sensor 55PP22-01 9307Z521A

Naka amaphuzu alandelayo ekuhlolweni kwe-ECU:

① Vala iswishi yokubasa: khipha ipulaki ye-ECU. ② Vula iswishi yokuthungela: sebenzisa i-multimeter ukuze uhlole ukunikezwa kwamandla kwe-ECU. I-voltage phakathi kwamaphini 2 no-3 wepulaki ye-ECU kanye ne-voltage phakathi kwamaphini 1 no-2 akufanele ibe ngaphansi kuka-11V, ngaphandle kwalokho, hlola isifunda.

2) Ukutholwa kwenzwa yezinga lokushisa elipholile ① Ukuhlolwa kwezintambo: Vala iswishi yokushisa bese ukhipha ipulaki elinezimbobo ezi-4 lenzwa yezinga lokushisa elipholile, njengoba kuboniswe kuMfanekiso 2-36. Hlola ukuthi ingabe ikhona yini isekethe evulekile ocingweni phakathi kwembobo yesi-3 yepulaki enezimbobo ezi-4 yenzwa yezinga lokushisa elipholile kanye nembobo engu-53 yesokhethi ye-ECU (ukumelana kwentambo akufanele kube kukhulu kuno-1.5Ω), nokuthi uma ucingo luyi-circuited isikhashana esigxotsheni esihle sokunikezwa kwamandla (ukumelana kufanele kungapheli). Hlola ukuthi ingabe ikhona yini isekethe evulekile ekuholeni phakathi kwembobo yokuqala yepulaki enezimbobo ezi-4 yenzwa yezinga lokushisa elipholile kanye nembobo engu-67 yesokhethi ye-ECU (ukumelana nomthofu akufanele kube kukhulu kuno-1.5Ω). ② Ukuhlolwa kokusebenza: Vala iswishi yokuthungela, susa inzwa yezinga lokushisa elipholile, faka inzwa yokushisa epholile enkomishini yamanzi, bese usebenzisa i-multimeter ukuze uthole ukumelana phakathi kwezikhonkwane 1 no-3 zenzwa yezinga lokushisa elipholile. Amanani ahambisanayo okushisa kwamanzi nokumelana kufanele ahlangabezane namanani aboniswe kuThebula 2-19. Ithebula 2-19 Ithebula Lezinga lokushisa Elihambisanayo kanye Nokumelana Nenzwa Yezinga Lokushisa Elipholile

3) Naka amaphuzu alandelayo lapho uthola inzwa yokuma kwe-crankshaft (inzwa yesivinini senjini): ① Vala iswishi yokushisa: khipha ipulaki elimhlophe elinezimbobo ezi-3 lenzwa yokuma ye-crankshaft (inzwa yesivinini senjini). ② Hlola ukumelana phakathi kwamapulaki: Njengoba kuboniswe kuMfanekiso 2-37, ukumelana phakathi kwezimbobo 1 no-3 (umhlabathi) naphakathi kwezimbobo 2 no-3 (umhlabathi) kufanele kungapheli. Hlola ukumelana phakathi kwephinikhodi 1 kanye nephinikhodi 2 yenzwa, okufanele ibe ngu-450 ~ 1000 Ω. Umgomo wokusebenza wedatha enwetshiwe ngokuvamile ukhipha isignali ye-pulse (igagasi elilinganiselwe le-sine noma igagasi elingunxande). Izindlela zokulinganisa isivinini sokujikeleza kwesignali ye-pulse zihlanganisa: indlela yokuhlanganisa imvamisa (okungukuthi, indlela yokuguqula i-F/V, umphumela wayo oqondile uyi-voltage noma yamanje) kanye nendlela yokusebenza kwemvamisa (umphumela wayo oqondile uyidijithali).

Kubuchwepheshe be-automation, kunezilinganiso eziningi zejubane lokujikeleza, futhi isivinini somugqa ngokuvamile silinganiswa ngokungaqondile ngesivinini sokujikeleza. I-DC tachogenerator ingaguqula isivinini sokujikeleza sibe isignali kagesi. I-tachometer idinga ubudlelwano bomugqa phakathi kwe-voltage ephumayo kanye nesivinini sokujikeleza, futhi idinga i-voltage ephumayo ukuthi ibe umqansa kanye nesikhathi nokuzinza kwezinga lokushisa kube kuhle. I-tachometer ingahlukaniswa ngokujwayelekile ibe izinhlobo ezimbili: uhlobo lwe-DC nohlobo lwe-AC. Inzwa yesivinini esijikelezayo ixhumene ngqo nento ehambayo. Uma into ehambayo ixhumene nenzwa yesivinini esijikelezayo, ukungqubuzana kushayela i-roller yenzwa ukuthi ijikeleze. Inzwa ye-pulse ejikelezayo efakwe kurola ithumela uchungechunge lwama-pulse. I-pulse ngayinye imele inani elithile lebanga, ukuze isivinini somugqa sikwazi ukukalwa. Uhlobo lokungeniswa kwe-electromagnetic, igiya lifakwe ku-shaft ejikelezayo, kanti uhlangothi olungaphandle luyikhoyili kagesi. Ukujikeleza kungenxa yegebe phakathi kwamazinyo egiya, futhi i-voltage eshintshayo yesikwele iyatholakala, bese kubalwa isivinini sokujikeleza. Inzwa yejubane ejikelezayo ayinakho ukuthintana okuqondile nento ehambayo, futhi ifilimu ekhanyayo ixhunywe onqenqemeni lwe-blade ye-impeller. Lapho uketshezi lugeleza, luqhubezela i-impeller ukuba ijikeleze, futhi i-optical fiber idlulisa ukukhanya kanye njalo ukujikeleza kwe-impeller ukuze kukhiqize isignali ye-pulse kagesi. Ijubane lingabalwa kusuka enanini lama-pulses atholiwe.
