Ukuxilongwa kweFault of Cummins 300KVA Generator Generator Supply System

1.Ukuxilongwa kweFault yoxinzelelo oluphezulu oluqhelekileyo lwenkqubo yokubonelela ngamafutha kaloliwe we-300kva Cummins iseti yejenereyitha yedizili.

I-sensor kunye ne-actuators ezisetyenziswe kwinkqubo yokunikezelwa kwamafutha kaloliwe aqhelekileyo aneempawu zenani elikhulu, ukuchaneka okuphezulu kunye neempendulo ezikhawulezayo.Ngethuba nje into enye yonakalisiwe, iya kuba nempembelelo enkulu kwinkqubo yonke, kwaye ikhokelela ekungaphumeleli kokusebenza okuqhelekileyo okanye ukuqala kwezixhobo.Iingxaki ezijongene nokuxilongwa kwesistim nazo zezona zibalulekileyo.

Ngenxa yokuba ulwakhiwo kunye nemo yokulawula yenkqubo yonikezelo lwamafutha kaloliwe ephezulu yoxinzelelo oluqhelekileyo yahluke kakhulu kwijenereyitha yedizili yemveli, iimpazamo kwinkqubo nazo zinzima kakhulu.Ngokuqhelekileyo, iimpazamo zinokwahlulwa zibe zezi ntlobo zilandelayo.

(1) Ukungaphumeleli kwenkqubo yokubonelela ngamafutha okubangelwa yinxalenye yoxinzelelo oluphantsi.

① Kukho ingxaki ngempompo yokuhambisa amafutha.Into ephosakeleyo kukuba i-injini igcina emva kokufudumala, isantya esingenamsebenzi asizinzile kwaye isantya sibuthathaka.Unokudibanisa igeyiji yoxinzelelo lweoyile kuthotho phakathi kwetanki yeoli kunye nesekethe yeoli yesihluzo se-oyile ephambili, jonga ixabiso loxinzelelo lwe-oyile (uxinzelelo lweoyile kufuneka lube lukhulu kune-3bar ngexesha lokunyuka ngokukhawuleza), gweba imeko yempompo yokuhambisa amafutha. , kwaye uphelise impazamo ngokulungisa okanye ukubuyisela ipompo yokuhambisa amafutha.

② Ingxaki yokucoca amafutha ibonisa ukuba kunzima ukuqala ukubanda, okubangelwa kakhulu ngamanzi amaninzi kwisihluzo okanye umonakalo kwi-heater, ngakumbi ebusika.Ebusika, amanzi kwisihluzo se 300kva Cummins generator kufuneka ikhutshwe rhoqo kwaye imeko yokusebenza ye-heater kufuneka ihlolwe.

(2) Ukungaphumeleli kwenkqubo yokubonelela ngamafutha okubangelwa yinxalenye yoxinzelelo oluphezulu.

Inxalenye yoxinzelelo oluphezulu lwenkqubo yokubonelela ngamafutha isebenzisa ikhamera yokuqhuba i-pump plunger yempompo yoxinzelelo oluphezulu phezulu nasezantsi ukugqiba ukufunxa ioli kunye nenkqubo yokumpompa.

① Kukho ingxaki ngempompo yoxinzelelo oluphezulu.Into ephosakeleyo kukuba umbhobho we-high-pressure ine-fuel pressure eyaneleyo ngenxa yomonakalo wamacandelo kwipompo yoxinzelelo oluphezulu.Impazamo yempompo yoxinzelelo oluphezulu inokugwetywa ngokufunda ikhowudi yephutha yenzwa yoxinzelelo oluqhelekileyo lukaloliwe kunye nohlalutyo lokuhamba kwedatha.

② Kukho ingxaki ngenzwa yoxinzelelo kaloliwe eqhelekileyo.Impazamo yenzeke kukuba injini iyazinza emva kokuba iqalile, kwaye ayinakuphinda iqalwe emva kokuma.Isizathu kukuba i-oyile yokulinganisa imbobo ye-sensor yoxinzelelo kaloliwe eqhelekileyo ivaliwe okanye i-sensor yonakalisiwe, okubangela umqondiso ongaqhelekanga we-sensor yoxinzelelo lwe-trail eqhelekileyo efunyenwe yi-ECU, ukunyanzela injini ukuba ivale.Sebenzisa i-multimeter okanye i-oscilloscope ukufumanisa umqondiso we-voltage ophumayo we-sensor (ixabiso eliqhelekileyo ngu-0.5 ~ 4.5V), ukuze ugwebe olu hlobo lwempazamo.

③ Kukho ingxaki ngevalve yokunciphisa uxinzelelo lukaloliwe.I-fault phenomenon inzima ukuqalisa, isantya esingazinzanga sokungenzi nto kunye nokukhawuleza okubuthathaka ngexesha lokuqhuba.Isizathu sesokuba uxinzelelo lwamafutha kumzila kaloliwe oqhelekileyo mkhulu kwaye ayonelanga ngenxa yokuvuza kwevalve yokunciphisa uxinzelelo lukaloliwe.Inokugwetywa ngokuhlalutya ukuhamba kwedatha ye-sensor yoxinzelelo lukaloliwe oluqhelekileyo kunye ne-detector okanye i-oscilloscope phantsi kwemeko yokufika.

④ Kukho ingxaki ngesitofu se-electronic fuel injection.Into ephosakeleyo kukuba kunzima ukuqala imoto eshushu kwaye umsi omnyama uphuma kumbhobho wokukhupha.Isizathu kukuba umxube utyebe kakhulu ngenxa yokutofa kakubi okanye ukuthontsiza kwe-oyile yesitofu se-electronic fuel.Jonga kwaye uhlalutye i-wave wave ye-injector yangoku ye-fuel injector nge-oscilloscope okanye umvavanyi ukuze ugwebe ngakumbi impazamo yesitofu se-fuel kwaye uyibuyisele endaweni yayo.

3. Ukungaqondi kakuhle ukuxilongwa kwempazamo kunye nokugcinwa.

Kwinkqubo yokukhangela impazamo kunye nomgwebo we-high-voltage yenkqubo kaloliwe eqhelekileyo yejenereyitha yedizili elawulwa ngombane, yindlela ethe ngqo ngakumbi yokufunda ngokuthe ngqo ikhowudi yempazamo kunye nesixhobo sekhompyuter ukuxilonga impazamo.Ngoko ke, abaninzi abasebenzi bezolondolozo basebenzisa ngokuthe ngqo ikhowudi yempazamo yokufunda ukugweba indawo yempazamo, okanye bazame ukuphelisa impazamo ngokutshintshela amacandelo kunye neengxenye eziboniswe yikhowudi yempazamo, Nangona kunjalo, impazamo ayinakupheliswa, kuba ikhowudi yempazamo ayifuni. kuthetha ukuba amalungu ekubhekiswa kuwo kwikhowudi yempazamo eneneni anempazamo.Oku kungenxa yokuba iimeko zempazamo kunye nemigangatho ebekwe yi-ECU kwicandelo ngalinye yahlukile, kwaye intsebenziswano phakathi kwamacandelo ahlukeneyo kunye nezinye izinto zikhona.Ezinye zeekhowudi eziphosakeleyo ezigcinwe yi-ECU zingabonakalisa imeko yangempela yephutha, ngelixa abanye abanako.Ngokomzekelo, ezinye iimpazamo zibangelwa yimpazamo yomatshini, eyenza ukuba umqondiso we-sensor uphambuke okanye udlule uluhlu, kwaye i-ECU iya kuxela i-sensor ye-sensor.Enyanisweni, i-sensor ayiyiyo indawo ephosakeleyo.

Ngamafutshane, ikhowudi yesiphoso ayithethi ukuba kufuneka kubekho impazamo, kwaye akukho khowudi yempazamo ayithethi ukuba akukho mpazamo.Ukuxilonga indawo yempazamo ngekhowudi yempazamo kunokusetyenziswa kuphela njengesalathiso.Kukwafuna ukuba abasebenzi bezolondolozo bamisele izinto eziphambili zokuhlola emva kokuhlalutya ngononophelo kunye nesigwebo ngokwamava aqokelelweyo, ulwazi kunye nobuchwepheshe.Ngoncedo lwezixhobo kunye neemitha zokubona iiparitha zokusebenza zamacandelo, sinokugweba ukunyaniseka kwekhowudi yephutha, sifumane isizathu sangempela sephutha kwaye sinqume indawo yephutha.
