Ukuxilongwa Kwephutha Kwe-Cummins 300KVA Generator Fuel Supply System

1.Ukuxilongwa kwephutha lomfutho ophakeme wesistimu kawoyela wesitimela ovamile we-300kva Cummins generator set diesel.

Izinzwa nama-actuator asetshenziswa kusistimu yokunikeza uphethiloli kaloliwe enengcindezi ephezulu anezici zenombolo enkulu, ukunemba okuphezulu kanye nempendulo esheshayo.Uma nje into eyodwa ilimele, izoba nomthelela omkhulu kulo lonke uhlelo, futhi iholele nasekuhlulekeni kokusebenza okujwayelekile noma ukuqaliswa kwemishini.Izinkinga ezibhekene nokuxilongwa kwephutha kohlelo nazo zibucayi kakhulu.

Ngenxa yokuthi ukwakheka kanye nemodi yokulawula yesistimu yokuphakelwa kukagesi kaloliwe enengcindezi ephezulu ihluke kakhulu kujeneretha kadizili evamile, amaphutha ohlelweni nawo ayinkimbinkimbi kakhulu.Ngokuvamile, amaphutha angahlukaniswa abe yizinhlobo ezilandelayo.

(1) Ukwehluleka kwesistimu yokuhlinzeka ngamafutha okubangelwa ingxenye yengcindezi ephansi.

① Kunenkinga ngephampu yokudlulisa uphethiloli.Iphutha wukuthi injini iyatota ngemuva kokufudumala, ijubane lokungenzi lutho alizinzi futhi nejubane liyancipha.Ungakwazi ukuxhuma igeji yomfutho kawoyela ochungechungeni phakathi kwethangi likawoyela kanye nesekhethi kawoyela yesihlungi sikaphethiloli esiyinhloko, hlola inani lomfutho kawoyela (umfutho kawoyela kufanele ube mkhulu kune-3bar ngesikhathi sokusheshisa), ukwahlulela isimo sephampu yokudlulisa uphethiloli. , futhi asuse iphutha ngokulungisa noma ngokushintsha iphampu yokudlulisa uphethiloli.

② Inkinga yesihlungi sikaphethiloli ibonisa ukuthi kunzima ukuqalisa ukubanda, okubangelwa ngokuyinhloko amanzi amaningi esihlungini noma ukulimala kwe-heater, ikakhulukazi ebusika.Ebusika, amanzi esihlungini 300kva Cummins generator kufanele ikhishwe njalo futhi isimo sokusebenza se-heater kufanele sihlolwe.

(2) Ukwehluleka kwesistimu yokuhlinzeka ngamafutha okubangelwa ingxenye yokucindezela okukhulu.

Ingxenye enengcindezi ephezulu yesistimu yokuphakelwa kukaphethiloli isebenzisa ikhamera ukushayela i-pump plunger yepompo yokucindezela okuphezulu phezulu naphansi ukuze iqedele inqubo yokudonsa uwoyela kanye nokumpompa.

① Kunenkinga ngepompo yomfutho ophezulu.Iphutha elenzeka ukuthi ipayipi elinengcindezi ephezulu linengcindezi kaphethiloli enganele ngenxa yokulimala kwezingxenye zephampu yomfutho ophezulu.Iphutha lepompo elinomfutho ophezulu lingahlulelwa ngokufunda ikhodi yephutha yenzwa evamile yokucindezela ujantshi kanye nokuhlaziywa kokugeleza kwedatha.

② Kunenkinga ngenzwa yomfutho wesitimela evamile.Iphutha elenzeka ukuthi injini iyama ngemuva kokuyiqala, futhi ayikwazi ukuphinda iqalwe ngemuva kokuma.Isizathu siwukuthi imbobo yokulinganisa uwoyela yenzwa evamile yokucindezela komzila wesitimela ivinjiwe noma inzwa yonakele, okuholela esignali engavamile yenzwa evamile yokucindezela komzila wesitimela etholwe yi-ECU, okuphoqa injini ukuba ivale.Sebenzisa i-multimeter noma i-oscilloscope ukuze uthole isignali ye-voltage ephumayo yenzwa (inani elivamile lingu-0.5 ~ 4.5V), ukuze wahlulele lolu hlobo lwephutha.

③ Kunenkinga nge-valve evamile yokunciphisa ingcindezi kajantshi.Isici sephutha kunzima ukuqala, isivinini sokungenzi lutho esingazinzile kanye nokusheshisa okubuthakathaka ngesikhathi sokushayela.Isizathu siwukuthi umfutho kaphethiloli kumzila wesitimela ovamile mkhulu futhi ayenele ngenxa yokuvuza kwevalvu evamile yokunciphisa umfutho wesitimela.Ingahlulelwa ngokuhlaziya ukugeleza kwedatha yenzwa yokucindezela komzila ovamile ngomtshina noma i-oscilloscope ngaphansi kwesimo sokufika.

④ Kunenkinga ngomjovo kaphethiloli we-elekthronikhi.Iphutha wukuthi kunzima ukudubula imoto eshisayo kanti kukhishwa intuthu emnyama epayipini le-exhaust.Isizathu ukuthi ingxube inothe kakhulu ngenxa yokungajovi kahle noma ukuconsa kwamafutha komjovo kaphethiloli we-elekthronikhi.Hlola futhi uhlaziye i-waveform yamanje yesijovo sikaphethiloli nge-oscilloscope noma isihloli ukuze uqhubeke nokwahlulela iphutha lesijojo sikaphethiloli bese usishintsha.

3. Ukungaqondi kahle ukuxilongwa kwephutha nokugcinwa.

Enqubweni yokuthola amaphutha kanye nokwahlulela kwesistimu yesitimela esine-voltage ephezulu yejeneretha kadizili elawulwa nge-elekthronikhi, kuyindlela eqondile yokufunda ngokuqondile ikhodi yephutha ngomtshina wekhompyutha ukuze kuhlonzwe iphutha.Ngakho-ke, izisebenzi eziningi zesondlo zisebenzisa ngokuqondile ikhodi yephutha efundiwe ukuze zihlulele indawo yephutha, noma zama ukuqeda iphutha ngokushintsha izingxenye nezingxenye eziboniswa ikhodi yephutha, Nokho, iphutha alikwazi ukuqedwa, ngoba ikhodi yephutha ayifuni. kusho ukuthi izingxenye okukhulunywe ngazo kukhodi yephutha zinephutha ngempela.Lokhu kungenxa yokuthi izimo zephutha kanye nemikhawulo ebekwe i-ECU engxenyeni ngayinye ihlukile, futhi ukuxhumana phakathi kwezingxenye ezihlukahlukene nezinye izici zikhona.Amanye amakhodi wephutha agcinwe yi-ECU angabonisa isimo sangempela sephutha, kuyilapho abanye bengakwazi.Isibonelo, amanye amaphutha abangelwa amaphutha emishini, okwenza isignali yenzwa iphambuke noma idlule ububanzi, futhi i-ECU izobika iphutha lenzwa.Eqinisweni, inzwa ayilona iphuzu lephutha.

Ngamafuphi, ikhodi yephutha ayisho ukuthi kufanele kube nephutha, futhi akukho khodi yephutha akusho ukuthi akumele kube nephutha.Ukuxilonga indawo enephutha ngekhodi yephutha kungasetshenziswa kuphela njengereferensi.Kudingeka futhi ukuthi izisebenzi ezinakekela isondlo zinqume izinto ezibalulekile zokuhlola ngemva kokuhlaziya nokwahlulela ngokucophelela ngokuya ngolwazi oluqoqiwe, ulwazi nobuchwepheshe.Ngosizo lwamathuluzi namamitha ukuthola imingcele yokusebenza yezingxenye, singakwazi ukwahlulela ubuqiniso bekhodi yephutha, sithole imbangela yangempela yephutha futhi sinqume indawo yephutha.
