Inzwa ye-urea

Ingxenye yangaphambili ye-Urea Pressure Sensor isetshenziselwa ukuthola ingcindezi ye-Urea, futhi ingxenye engemuva ibhekele ukuthola ingcindezi yokuxuba i-urea nomoya egumbini lokuxuba. Lapho ingxenye yehluleka: Ukusetshenziswa kwe-Urea akuyona into engajwayelekile, futhi imoto ikhanyisa ukukhanya kwephutha. Lapho ikhodi yephutha iyiphutha lamanje, ukusebenza kwenjini kukhawulelwe ngesivinini kanye ne-torque.

Amapharamitha wokuhlola kanye nokugcina:

Sebenzisa i-multimeter ukukala i-voltage evulekile ye-Urea Pressure Sensor, vula inkinobho yokhiye futhi ungeze i-plug ekhiye, futhi ulinganise i-5V (amandla), 0V (isinali) kanye ne-0V (GRAIR) ne-0V (Ground). Ukukala i-voltage evaliwe-circuit, qala ngokuvula ukhiye, uxhume ku-plug bese wephula ucingo ngemuva ukuze ulinganise ama-voltage, ukukala i-5V (amandla) kanye ne-0V (Ground) ne-0V (Ground).

Amakhodi wephutha ahlobene:

Imibono yokuhlola umugqa:

1. Sebenzisa i-multimeter ukukala i-voltage evulekile ye-plug njengoba i-5V (amandla), 0V (isinali), 0V (isignali), ukumelana nomhlabathi kungaphansi kwe-0.2ω

2

3. Iphutha le-FC3572 libikiwe, elivame ngenxa yokuvula umjikelezo womugqa woMkhakha Wamandla noma umugqa wesiginali, umjikelezo omfushane oya emhlabathini noma ukulimala kwangaphakathi kwengxenye.

4. Bika amaphutha we-FC3573, ngokuvamile ngoba ipulaki ikhululiwe, ukuxhumana okubonakalayo noma ukulimala kwangaphakathi kwengxenye

Imibono yokuhlola ukusebenza:

1. Gxila ekubhekeni ukuthi ipulaki yeposi ye-Urea Dosing inokuxhumana okubonakalayo, ukungena kwamanzi kanye nokugqwala.

2. Lapho inzwa ye-Urea Pressing Sensor ibika kakhulu noma iphansi, hlola ukuthi inzwa yokuzwa insimbi yensimbi ikhubazekile noma ilimele nokuthi ngabe ukubekwa uphawu kulimele yini nokuthi ngabe kulimele yini ukuthi ukubekwa uphawu.

3. Ukuze uvikele ama-alamu wamanga abangelwa inzwa ye-Urea Pressure ye-Acnomeral Deplor, izakhi zingashintshwa ukuze zihlolwe.

4. Ikhodi yefoni ye-FC4239 ibika. Ngokuvamile, abaqaphi be-ECM ukuthi ingcindezi yangempela iphakeme kakhulu futhi ibika iphutha. Inani lengcindezi elihlanganisiwe lengcindezi kufanele libe phakathi kuka-330 ~ 430KPA lapho i-Urea Dosing Pump isilungele ukujova (umjovo wangaphambi kokuphumelela) kanye nesigaba somjovo. Uma i-ECM ibona ukuthi ingcindezi yangempela ingaphezulu kuka-500kpa futhi iyaqhubeka isikhathi esingaphezu kwama-8s, izobika iphutha; Noma esiteji sangaphambilini, kuzobika iphutha uma liphakeme kune-150kpa futhi liqhubeke ngo-0.5s. Isizathu esingaba khona:

①I-nozzle ivinjelwe, ipayipi lomjovo ligobile futhi livinjelwe;

②Izinkristalu ze-urea ngaphakathi kwephampu ye-urea zivinjiwe;

③Ingcindezi yomoya ecindezelwe iphakeme kakhulu;

④ Bheka ukuthi ngabe ishidi lensimbi elizwakalayo lensor yokuxuba inzwa yokuxuba inzwa;

Ikhodi ye-FC4238 yeKC4238 ibika. Ngokuvamile, abaqaphi be-ECM ukuthi ingcindezi yangempela iphansi kakhulu futhi ibika iphutha. Inani lengcindezi elihlanganisiwe lengcindezi kufanele libe phakathi kuka-330 ~ 430KPA lapho i-Urea Dosing Pump isilungele ukujova (umjovo wangaphambi kokuphumelela) kanye nesigaba somjovo. Isizathu esingaba khona:

Ingcindezi yomoya engenele;

②Izinkristalu ze-urea ngaphakathi kwephampu ye-urea zivinjiwe;

③ Bheka ukuthi ngabe ishidi lensimbi lensimbi lilimele nokuthi i-O-ring yonakele yini;

I-valve yendlela eyodwa yendlela yegesi ilimele noma isikrini sokuhlunga sivinjiwe;

⑤ Ukuvuza okuvuzayo;
