Ana amfani da firikwensin matsin lamba na Ford 55PP22-01 9307Z521A

Kula da abubuwan da ke gaba a gwajin ECU:

① Kashe maɓallin kunnawa: cire filogin ECU. ② Kunna maɓallin kunnawa: yi amfani da multimeter don bincika wutar lantarki na ECU. Wutar lantarki tsakanin fil 2 da 3 na filogin ECU da ƙarfin lantarki tsakanin fil 1 da 2 bai kamata ya zama ƙasa da 11V ba, in ba haka ba, duba kewaye.

2) Gano firikwensin zafin jiki mai sanyaya ① Duban waya: Kashe maɓallin kunnawa kuma cire filogin 4-rami na firikwensin zafin jiki, kamar yadda aka nuna a hoto 2-36. Bincika ko akwai buɗaɗɗen da'ira a cikin waya tsakanin rami na 3 na ramuka 4 na firikwensin zafin jiki na coolant da rami na 53 na soket na ECU (juriyar waya bai kamata ya fi 1.5Ω), kuma ko waya yana ɗan gajeren kewayawa zuwa madaidaicin sandar wutar lantarki (juriya ya kamata ya zama marar iyaka). Bincika ko akwai buɗaɗɗen da'ira a cikin jagorar tsakanin rami na farko na filogi 4-rami na firikwensin zafin jiki mai sanyaya da rami na 67 na soket na ECU (juriyar gubar bai kamata ya wuce 1.5Ω ba). ② Duban aiki: Kashe maɓallin kunnawa, cire firikwensin zafin jiki mai sanyaya, sanya firikwensin zafin jiki mai sanyaya cikin kofin ruwa, sannan yi amfani da multimeter don gano juriya tsakanin fil 1 da 3 na firikwensin zafin jiki mai sanyaya. Ma'auni masu dacewa na zafin ruwa da juriya ya kamata su hadu da dabi'un da aka nuna a cikin Table 2-19. Tebura 2-19 Madaidaicin Teburin Zazzabi da Juriya na Sensor Zazzabi Mai Sanyi

3) Kula da abubuwan da ke biyo baya lokacin gano firikwensin matsayi na crankshaft ( firikwensin saurin injin): ① Kashe maɓallin kunnawa: cire filogin farin 3-rami na firikwensin matsayi na crankshaft ( firikwensin saurin injin). ② Duba juriya tsakanin matosai: Kamar yadda aka nuna a Hoto 2-37, juriya tsakanin ramukan 1 da 3 (ƙasa) da tsakanin ramukan 2 da 3 (ƙasa) ya kamata ya zama marar iyaka. Duba juriya tsakanin fil 1 da fil 2 na firikwensin, wanda yakamata ya zama 450 ~ 1000 Ω. Ka'idar aiki na tsawaita bayanai galibi tana fitar da siginar bugun jini (kimanin kalaman sine ko kalaman rectangular). Hanyoyin auna saurin jujjuyawar siginar bugun jini sun haɗa da: Hanyar haɗa mitoci (wato, hanyar jujjuyawar F/V, wanda sakamakonsa kai tsaye shine ƙarfin lantarki ko halin yanzu) da kuma hanyar aiki ta mitar (wanda sakamakonsa kai tsaye dijital).

A cikin fasaha ta atomatik, akwai ma'auni masu yawa na saurin juyi, kuma ana auna saurin layin a kaikaice ta hanyar juyawa. DC tachogenerator na iya canza saurin juyawa zuwa siginar lantarki. Tachometer yana buƙatar alaƙar layi tsakanin ƙarfin fitarwa da saurin juyi, kuma yana buƙatar ƙarfin fitarwa ya zama m kuma lokaci da kwanciyar hankali ya kasance mai kyau. Za a iya raba tachometer gaba ɗaya zuwa nau'i biyu: nau'in DC da nau'in AC. Firikwensin saurin juyawa yana cikin hulɗa kai tsaye tare da abu mai motsi. Lokacin da abu mai motsi ya kasance yana hulɗa da firikwensin saurin jujjuya, juzu'in yana motsa abin nadi na firikwensin don juyawa. Na'urar firikwensin bugun jini mai jujjuya wanda aka ɗora akan abin nadi yana aika jerin bugun jini. Kowane bugun jini yana wakiltar takamaiman ƙimar nisa, ta yadda za a iya auna saurin layin. Nau'in shigar da wutar lantarki, ana shigar da kayan aiki akan madaidaicin juzu'i, kuma gefen waje shine na'urar lantarki. Juyawa yana faruwa ne saboda tazarar da ke tsakanin haƙoran kayan aikin, kuma ana samun ƙarfin wutar lantarki mai canzawa na murabba'i, sannan ana ƙididdige saurin juyawa. Na'urar firikwensin saurin jujjuyawar ba shi da hulɗar kai tsaye tare da abu mai motsi, kuma an haɗa fim ɗin mai nuni zuwa gefen ruwan wukake na impeller. Lokacin da ruwa ya gudana, yana motsa mai motsa jiki don juyawa, kuma fiber na gani yana watsa hasken haske sau ɗaya kowane juyi na abin motsa jiki don samar da siginar bugun jini. Ana iya ƙididdige saurin daga adadin bugun da aka gano.
