Uhlalutyo lwembangela kunye nesisombululo se-Diesel Generator Injector Failure

I-injector ye-injini ye-diesel ifakwe kwi-cylinder head, umsebenzi we-diesel fuel ngendlela ye-atomized particles ecocekileyo kwigumbi lokutsha kunye nomxube womoya, ukwenza i-nozzle yegumbi lokutshisa i-injini ye-diesel, umsebenzi wexesha elide kwiqondo lokushisa eliphezulu kunye nokuphakama okuphezulu. Uxinzelelo kunye nemeko ye-corrosion yegesi, ukuhamba kwesantya esiphezulu sangaphakathi seendawo ezihambayo zokungcola okuncinci komatshini kwi-fuel kunye ne-fuel ehlanjwe ngokuphindaphindiweyo.Kulula ukunxiba kunye nokudleka kwaye lelinye lawona malungu anengxaki kwinkqubo yamafutha enjini yedizili.Namhlanje, i-Dingbo Electric Power, i umenzi wejenereyitha , iya kukwazisa kuwe uhlalutyo lwesizathu kunye nesisombululo sokungaphumeleli kwe-diesel injector.

1.I-atomization engafanelekanga yesitofu samafutha.

Xa uxinzelelo lwenaliti luphantsi kakhulu, ukunxiba komngxuma wejethi kunekhabhoni, ukunxiba kwentwasahlobo okanye ukwehla kwe-elastic kuya kubangela ukuba i-injector ivuleke kwangaphambili, ukulibaziseka ukuvala, kwaye yenze into ye-atomization yesitshizi esibi. umsebenzi;Ukuba i-multi-cylinder injini ye-diesel ihla amandla, i-exhaust iqhuma, umatshini oqhuba isandi awuqhelekanga.Ukongeza, ngenxa yokuba i-droplet yedizili enesayizi enkulu kakhulu ayinakutshiswa ngokupheleleyo, iqukuqela kwipani yeoli ecaleni kodonga lwesilinda, eyonyusa inqanaba leoli, inciphise i-viscosity, yonakalise ukuthambisa, kwaye inokubangela ingozi yokutshisa ioli. walla cylinder.

Isisombululo: i-injector kufuneka ihlanjululwe ukucoca, ukugcinwa, ukulungiswa kwakhona.

2.I-Fuel injector return line yonakalisiwe.

Xa ivalufa yenaliti igugile kakubi okanye umzimba wevalve yenaliti ungahambelani ngokusondeleyo neqokobhe le-injector, ukubuyiswa kwe-oyile ye-injector kwanda kakhulu, okunye ukuya kuthi ga kwi-0.1 ~ 0.3kg/h.Ukuba umbhobho we-oyile obuyayo wonakaliswe okanye uvuza, i-oyile yokubuyisela iya kulahleka ize, ibangele inkunkuma.

Ngoko ke, umbhobho wokubuyisela kufuneka ucoceke kwaye uvalwe ukuze ioli yokubuyisela ikwazi ukuhamba kakuhle kwi-tank.Ukuba umbhobho wokubuyisela uqhagamshelwe kwisihluzo se-diesel, i-terminal yayo kufuneka imiselwe ivalve yendlela enye ukuthintela idizili kwisihluzo kwi-injector.

3.Iholo yevalve yenaliti yandisiwe.

Ngenxa yenaliti eqhubekayo kunye nokhukuliseko lokuhamba kweoyile yoxinzelelo oluphezulu, umngxuma wombhobho wevalve yenaliti uya kunxiba kancinci kancinci, okukhokelela ekunciphiseni koxinzelelo lwenaliti, umgama wenaliti uyafinyezwa, i-atomization yedizili ayilunganga, kunye nediphozithi yekhabhoni. i-cylinder iya kwanda.

Isisombululo: umngxuma wesitofu somngxuma omnye sikhulu kune-1mm, kwaye ibhola yentsimbi enobubanzi obuyi-4 ~ 5mm inokubekwa ekupheleni komngxuma, kwaye inyando ngobuchule ngehamile ukwenza uguquko lweplastiki yendawo. umngxuma we-nozzle kwaye unciphise indawo yokuvula.Isitofu esinemingxuma ngokuthe ngqo ngenxa yenani lemingxuma, indawo encinci yokuvula, banokusebenzisa kuphela isantya esiphezulu sentsimbi yokusila i-punch emngxunyeni ngokunkqonkqoza ngobunono, ukuba i-debugging ayifanelekanga, ivalve yenaliti kufuneka itshintshwe.

4.inaliti yokulunywa kwevalve.

Amanzi okanye iasidi kwi-oyile yedizili iya kwenza ivalve yenaliti ibe nomhlwa kwaye ixinge.Emva kokuba i-cone yokutywina yevalve yenaliti yonakele, igesi evuthayo kwi-cylinder iya kufakwa kwindawo efanelekileyo ukuze yenze idiphozithi yekhabhoni ukwenzela ukuba i-valve yenaliti ibulawe, kwaye i-injector iya kulahlekelwa yi-injection yayo, okukhokelela kwi-cylinder. ukuyeka ukusebenza.

Isisombululo: Ivalve yenaliti inokuba zibini kwi-oyile esetyenzisiweyo eshushu ukuze ibilise emsini, emva koko isuse kwaye usebenzise iphedi ngelaphu elithambileyo ngesandla vice clamp inaliti umsila kancinci, izoba kwioyile ecocekileyo, vumela ivalve yenaliti kumsebenzi womzimba wevalvu. ukugaya ngokuphindaphindiweyo, de ivalve yenaliti idibanise ivalve yesandla seyure yehashe ukusuka kumzimba wevalvu ukuze irhoxe kancinci.Ukuba uvavanyo lwe-injector alufaneleki, ivalve yenaliti kufuneka itshintshwe.

5.Nxiba ebusweni bomzimba wenaliti.

Isiphelo somzimba wevalve yenaliti isiphelo sobuso ngokujikeleza okuphindaphindiweyo kwempembelelo yevalve yenaliti, ixesha elide liya kwenza ngokuthe ngcembe umngxuma, ngaloo ndlela linyusa ukunyuswa kwevalve yenaliti, kwaye kuchaphazele ukusebenza okuqhelekileyo kwesitofu.

Isisombululo: umzimba wenaliti unokunqunyulwa kwi-grinder ukugaya lo buso bokuphela, kwaye emva koko ugaye ngentlama ecolekileyo yokusila kwipleyiti yeglasi.

I-6.I-injector ye-Fuel kunye ne-cylinder head joint hole ukuvuza i-oyile yomzila.

Xa i-fuel injector ifakwe kunye nentloko ye-cylinder, idiphozithi yekhabhoni kumngxuma wofakelo kufuneka isuswe ngokucophelela.I-gasket yobhedu kufuneka ibe tyaba, kwaye ipleyiti ye-asbestos okanye ezinye izinto aziyi kusetyenziselwa ukuyibuyisela endaweni, ukwenzela ukuthintela ukutshatyalaliswa kobushushu obungalunganga okanye umphumo wokutywinwa.

Ukuba i-washer yobhedu yenziwe, kufuneka icutshungulwe ngobhedu ngokobunzima obuchaziweyo ukuze kuqinisekiswe ukuba umgama we-injector ophuma kwinqwelo yentloko ye-cylinder uhlangabezana neemfuno zobugcisa.Ukongeza, i-injector pressure plate concave kufuneka ifakwe ezantsi, qinisa ukuphepha i-unilateral bias, kufuneka iqiniswe ngokuhambelana ne-torque echaziweyo ngokulinganayo, ngaphandle koko intloko ye-injector iya kuba ngenxa yokuphambuka kunye nokuvelisa ioli yokuhambisa igesi.

7.Ivalve yenaliti kunye nenaliti yesikhokelo sokunxiba ubuso.

Intshukumo ephindaphindiweyo yevalve yenaliti kumngxuma wevalve yenaliti, kudityaniswa nokuhlasela kobumdaka kunye nobumdaka ngaphakathi. ioli yedizili , iya kwenza umphezulu wesikhokelo somngxuma wevalve yenaliti ngokuthe ngcembe unxibe ukuze isithuba sande okanye kukho imikrwelo, okukhokelela ekwandeni kokuvuza kwe-injector, uxinzelelo luyancitshiswa, inani lenaliti yamafutha liyancitshiswa, inaliti. ixesha lag, okukhokelela ekuqaliseni injini ye-diesel kunzima.

Isisombululo: Xa ukulibaziseka kwexesha lokutofa kuninzi kakhulu, i-locomotive ayikwazi nokubaleka, ngeli xesha kufuneka ithathe indawo yesibini sevalve yenaliti.

I-8.Amaconsi eoli avela kwi-injector.

Xa i-injector isebenza, i-cone yokutywina yomzimba wevalve yenaliti iya kuba phantsi kweempembelelo ezinamandla rhoqo zevalve yenaliti, kunye nokuhamba kweoli yoxinzelelo oluphezulu rhoqo ukusuka kwinaliti ngaphandle, i-cone iya kuvela ngokuthe ngcembe i-nicks okanye amabala, ngaloo ndlela. ukulahlekelwa isitywina, okubangela amathontsi yeoli ye-injector.

Xa iqondo lobushushu le-injini ye-diesel lisezantsi, umbhobho wokukhupha umoya ukhupha umsi omhlophe, ubushushu be-injini bunyuke uze emva koko ube ngumsi omnyama, kwaye umbhobho wokukhupha umoya uya kukhupha isandi sompu esingaqhelekanga.Ngeli xesha, ukuba ukunikezelwa kweoli kwi-cylinder kumisiwe, isandi sokukhutshwa komsi kunye nokudubula kuya kunyamalala.

Isisombululo: i-injector inokutshatyalaliswa, kwintloko yevalve yenaliti kunye ne-chromium oxide encinci ye-fine grinding intlama (nikela ingqalelo ukuba ungabambeleli kumngxuma wevalve yenaliti) ukugaya i-cone, uze uhlambulule ngeoli ye-diesel, kwi-injector test.Ukuba awukafaneleki, kufuneka utshintshe izincedisi zevalve yenaliti.
