Izilumkiso zoLondolozo lweGenereyitha yeDizili yeDizili kaLoliwe

Umenzi wejenereyitha yedizili yaseCummins ikufundisa ulwazi lolondolozo: izilumkiso zokugcinwa kwamandla ombane aphezulu ombane oqhelekileyo wejenereyitha yedizili.

1. Ukusetyenziswa kwemihla ngemihla

Uxinzelelo oluphezulu lwejenereyitha yedizili kaloliwe ixhotyiswe ngokubanzi nge-preheater.Xa iqalwa phantsi kwemekobume yobushushu obuphantsi, i-preheating switch inokuvulwa kuqala.Xa isibane sesalathiso se-preheater sivuliwe, kubonisa ukuba i-preheater iqala ukusebenza.Emva kwexesha lokufudumala, i-diesel generator inokuqaliswa emva kokuba isalathisi sokufudumala sivaliwe.Isalathisi sokufudumala sinomsebenzi we-alamu.Ukuba isalathisi sokufudumala sikhanya ngexesha lokusebenza kwejenereyitha yedizili eqhelekileyo, ibonisa ukuba ijenereyitha yedizili inkqubo yolawulo ayiphumelelanga kwaye kufuneka ilungiswe ngokukhawuleza.

Musa ukusebenzisa amanzi anoxinzelelo oluphezulu ukugungxula inkqubo yokutofa kwamafutha ejenereyitha yedizili kaloliwe eqhelekileyo, kuba emva kokuba amanzi engena kwiyunithi yokulawula i-elektroniki, inzwa, i-actuator kunye nesinxibelelanisi sayo, isinxibelelanisi sihlala sigqwala, nto leyo ekhokelela “kwimpazamo ethambileyo”. kunzima ukuyifumana kwinkqubo yolawulo yombane.

Iyunithi yokulawula i-elektroniki, inzwa kunye ne-actuator ye-high-voltage eqhelekileyo yejenereyitha ye-diesel kaloliwe inomdla ngakumbi kumbane.Nokuba ibhetri inelahleko encinci yamandla, iya kuchaphazela ukusebenza okuqhelekileyo kwenkqubo yolawulo lombane.Ngoko ke, kuyimfuneko ukugcina umthamo wokugcina ibhetri ngokwaneleyo.Ukuba ukulungiswa kwe-welding kuqhutyelwa kwi-high-voltage common rail diesel generator, intambo yebhetri kufuneka ihlanjululwe, ikhonkco ye-ECU kufuneka ikhutshwe, kwaye kungcono ukususa iyunithi yokulawula i-elektroniki echanekileyo.Iiyunithi zolawulo lwe-elektroniki, ii-sensor, ii-relays, njl. zizinto eziphantsi kwe-voltage, kunye ne-overvoltage eveliswa ngexesha le-welding kulula kakhulu ukutshisa ezi zixhobo zombane zingentla.

Ukongezelela, umsebenzi olandelayo unokuqhutyelwa kuphela emva kokuba i-generator ye-diesel ye-high-pressure eqhelekileyo ivaliwe ubuncinane ubuncinane be-5min, ukwenzela ukukhusela ukulimala komntu okubangelwa yi-injection ye-fuel-pressure.

2. Amanyathelo okucoca

Uxinzelelo oluphezulu oluqhelekileyo lwe-diesel generator ineemfuno ezingqongqo kakhulu kwiimveliso zeoli, kunye nomxholo wesulfure, i-phosphorus kunye nokungcola kuphantsi kakhulu.Kufuneka kusetyenziswe i-oyile ye-diesel ekhanyayo ekumgangatho ophezulu kunye ne-oyile ye-injini.I-oyile ye-diesel ekumgangatho ophantsi kulula ukubangela ukuvaleka kunye nokuguga okungaqhelekanga kwezitofu zamafutha.Ngoko ke, kuyimfuneko ukukhupha rhoqo amanzi kunye ne-sediment kwi-oil-water separator, kwaye uhlambulule rhoqo okanye ubeke indawo yokucoca i-diesel kunye ne-oyile yokucoca.Ngenxa yokuba umgangatho wedizili osetyenziswa ziiseti zejenereyitha yasekhaya kunzima ukuhlangabezana ngokupheleleyo neemfuno zoxinzelelo oluphezulu lwejenereyitha yedizili, kuyacetyiswa ukuba kusetyenziswe izongezo zedizili ezikhethekileyo zokongeza kwitanki yamafutha kunye nokucoca unikezelo lwamafutha. inkqubo rhoqo.

Phambi kokuba uqhaqhe inkqubo yokutofa kwe-fuel, okanye xa umbhobho wamalungu enkqubo yokutofa ngamafutha (njenge-injector yamafutha, umbhobho wokuhanjiswa kwe-oyile, njl. njl.) ufunyaniswa ungcoliswe luthuli, kuyacetyiswa ukuba kusetyenziswe isixhobo sokufunxa uthuli ukufunxa uthuli olujikelezileyo. , kwaye ungasebenzisi igesi ephezulu yoxinzelelo, ukugungxulwa kwamanzi oxinzelelo oluphezulu okanye ukucocwa kwe-ultrasonic.

Igumbi lokubeka ijenereyitha yolondolozo kunye nezixhobo kufuneka zigcinwe zicoceke kakhulu ukuthintela ukufumba kothuli.Kwigumbi lokubeka i-generator yesondlo, iinqununu kunye neefayili ezingcolisa inkqubo ye-injection ye-fuel ayivumelekanga, kunye noomatshini be-welding, oomatshini bokugaya kunye nezinye izixhobo ezinokungcolisa inkqubo ye-injection ye-fuel ayivumelekanga.

Impahla yabaqhubi bezolondolozo iya kucoceka, kwaye ayivumelekanga ukuthwala uthuli kunye neetshiphu zetsimbi.Akuvumelekanga ukunxiba iimpahla ezimfumamfuma ukunqanda ukungcolisa inkqubo yokutofa ngamafutha.Hlamba izandla phambi kokuba usebenze.Ukutshaya kunye nokutya akuvumelekanga ngokupheleleyo ngexesha lokusebenza.

3. Ukuqhaqha, ukugcinwa kunye nokuthuthwa kwamacandelo.

Emva kololiwe oqhelekileyo woxinzelelo oluphezulu iseti yokuvelisa idizili iyabaleka, akuvumelekanga ukuqhaqha inkqubo yokutofa kaloliwe yoxinzelelo oluphezulu.Xa ususa okanye ufaka umbhobho wokubuyisela i-oyile wempompo yeoli yoxinzelelo oluphezulu, nyanzela kwicala le-axial ukunqanda ukugoba.I-nut nganye iya kuqiniswa kwi-torque echaziweyo kwaye ayiyi konakala.Emva kokuba inkqubo yokunikezelwa kweoli ichithwa, nokuba ikhefu lifutshane kakhulu, i-cap yokukhusela ecocekileyo kufuneka igqitywe ngokukhawuleza, kwaye i-cap yokukhusela ingasuswa ngaphambi kokuhlanganiswa kwakhona.Izixhobo zoxinzelelo oluphezulu lwenkqubo yokutofa kaloliwe kufuneka zikhutshwe phambi kokusetyenziswa, kwaye umnqwazi okhuselayo kufuneka ususwe ngaphambi kokuhlanganisa.

Xa ugcina kwaye uhambisa i-high-pressure common common rail generator parts, i-injector ye-fuel, i-high-pressure oil pump assembly, i-fuel rail assembly kunye nezinye izinto ze-injection system ziya kunxiba ii-caps zokukhusela, kwaye i-injector ye-fuel iya kusongelwa ngephepha leoli.Amalungu aya kuthintelwa ekungqubekeni ngexesha lothutho.Xa uthatha kwaye ubeka, banokubamba kuphela umzimba wamalungu.Akuvumelekanga ukubamba amakhonkco e-inlet kunye nemibhobho yeoli yokuphuma kunye nemingxuma yomlomo wesitofu se-fuel, ukuze ugweme ukungcolisa inkqubo yoxinzelelo oluphezulu lwe-injection kaloliwe.
