Cov roj injectors puas tuaj yeem kho tau?

Roj injector tsis ua hauj lwm yog mob taub hau loj rau txhua tus tswv cuab hnyav. Thaum ntsib cov tsos mob xws li lub zog tsis txaus, haus luam yeeb ntau dhau, lossis txo qis kev lag luam roj, lawv cov lus nug tseem ceeb tshaj plaws yog: "Puas tau kho cov tshuaj txhaj tshuaj no, lossis lawv puas tuaj yeem hloov tau?" Hauv luv luv, cov lus teb yog yog, qee zaum cov tshuaj txhaj tshuaj tuaj yeem kho tau, tab sis qhov no tsis yog panacea thiab feem ntau yog nyob ntawm hom kev puas tsuaj, tus nqi - kev tshuaj xyuas cov txiaj ntsig, thiab koj cov kev xav tau zoo rau cov khoom siv.

Rau cov kev siv tseem ceeb ntawm Caterpillar xyaw, xaiv cov khoom siv siab - zoo nrog kev ruaj ntseg zoo, xws liCAT 326-4756 roj injector, feem ntau yog qhov kev ntseeg siab tshaj plaws thiab tus nqi - siv tau ntev - lub tswv yim los kho qhov kev ua tau zoo thiab tiv thaiv kev puas tsuaj rau tus nqi qis.

 

 

Qhov ua tau ntawm kev kho roj injector yog nyob ntawm qhov xwm txheej thiab qhov ua haujlwm tsis zoo. Qee qhov teeb meem tuaj yeem kho tau, thaum lwm tus ua kom kho tsis tau lossis tseem pheej hmoo.

Cov xwm txheej hauv qab no feem ntau pom zoo rau kev kho:

Clogging thiab kis kab mob: Cov kab mob sab hauv yog txhaws los ntawm cov pa roj carbon deposits los yog impurities los ntawm cov neeg pluag- roj zoo, uas feem ntau yuav kho tau los ntawm kev tu ultrasonic tu thiab kuaj.

Hnav cov ntsaws ruaj ruaj thiab O-rings: Cov roj tawm sab nraud los yog cua nkag yog feem ntau tshwm sim los ntawm kev laus cov ntsaws ruaj ruaj, uas tuaj yeem hloov tau raws li ib feem ntawm cov khoom siv sealing.

Me me nozzle hnav: Cov hnav me me ntawm qhov kawg ntawm cov roj injector nozzle tuaj yeem kho tau los ntawm qhov tseeb honing, lossis qee zaum, lub nozzle yuav tsum tau hloov.

Nws raug pom zoo kom hloov lub injector nyob rau hauv cov xwm txheej hauv qab no:

Internal mechanical tsis ua hauj lwm: lub caij nplooj ntoos hlav tawg hauv lub cev txhaj tshuaj, daig plunger, lossis lub tog raj kheej khawb hnyav.

Solenoid valve / hluav taws xob txhaum: Lub solenoid valve uas tswj kev ua haujlwm ntawm cov roj injector yog hlawv tawm lossis luv luv -circuited.

Kev puas tsuaj loj ntawm lub nozzle: Lub taub hau lub taub yog tawg, corroded, los yog yaj dhau kev kho, uas yuav cuam tshuam rau cov qauv ntawm cov roj txhaj tshuaj thiab lub cav combustion.

Rau cov khoom tseem ceeb xws li CAT 326-4756 injector, uas yog tsim tshwj xeeb rau kev xav tau siab -siab cov kab ke ntawm C4.2 thiab C6.4 cov cav, kom ntseeg tau meej meej thiab kev ntseeg tau yog qhov tseem ceeb tshaj plaws. Xaiv ib qho khoom tshiab, zoo tshaj plaws hloov ib feem los ntawm tus neeg muag khoom txhim khu kev qha ua kom muaj kev ua tau zoo thiab tshem tawm qhov kev pheej hmoo ntawm cov teeb meem ntxiv xws li lub tog raj kheej dej los yog turbocharger kev puas tsuaj los ntawm "kho" cov injectors.

 

 

Thaum ib qho kev txhaj tshuaj tsis ua haujlwm, feem ntau muaj peb txoj kev daws teeb meem, txhua tus nrog nws tus kheej cov nqi, sijhawm, thiab kev cuam tshuam kev ntseeg.

1. Kev tu tu: Qhov no yuav tsum tau siv cov cuab yeej tshwj xeeb, xws li cov tshuaj ntxuav ultrasonic thiab siab -siab txaus ntsuas lub rooj zaum, kom tshem tawm cov pa roj carbon deposits. Qhov no yog ib qho kev lag luam thiab kev daws teeb meem zoo rau cov khoom qias neeg tab sis mechanically intact injectors. Nws tsis tuaj yeem kho qhov hnav lossis puas lawm.

2. Injector refurbishment/remanufacturing: Qhov no yog txheej txheem kho dua tshiab. Cov tshuaj txhaj tshuaj yuav raug muab tshem tawm thiab ntxuav tag nrho, hnav cov khoom (xws li nozzles, ntsaws ruaj ruaj, thiab qee zaum li qub) yuav raug hloov nrog cov khoom tshiab, thiab tag nrho cov chav tsev yuav raug rov ua dua kom tau raws li cov khoom qub. Qhov no tuaj yeem yog qhov kev sib haum xeeb zoo, rov qab ua haujlwm ntawm tus nqi qis dua li hloov cov tshuaj txhaj tshuaj.

3. Kev hloov ua kom tiav: Qhov no txhais tau hais tias txhim kho cov tshuaj txhaj tshuaj tshiab. Nws muaj kev ntseeg siab tshaj plaws lav, tag nrho lub Hoobkas ua tau zoo, thiab feem ntau muaj lub sijhawm lav ntev tshaj plaws. Rau cov khoom tseem ceeb, qhov no feem ntau yog qhov kev xaiv zoo tshaj plaws los xyuas kom meej lub sijhawm ua haujlwm siab tshaj plaws thiab tiv thaiv koj lub cav peev.

 

 

Kev kuaj mob kom raug yog thawj kauj ruam hauv kev xaiv txoj kev daws teeb meem. Cov hauv qab no yog cov tsos mob tseem ceeb ntawm hom kev ua tsis tiav:

Cov tsos mob ntawm injector blockage:

Lub cav misfire, tsis ruaj tsis khov, thiab lub zog poob tseem ceeb.

Pib nyuaj, tshwj xeeb tshaj yog thaum pib lub cav txias.

Kev siv roj ntau ntxiv yog tshwm sim los ntawm ECU sim los them nyiaj rau kev sib tsoo tsis zoo.

Cov tsos mob ntawm roj injector to:

Roj tsw ntxhiab, pom dampness nyob ib ncig ntawm cov roj injector vaj tse, los yog roj sib xyaw nrog cov roj cav.

Cov yeeb nkab tso pa tawm ntau cov pa luam yeeb dub lossis dawb.

Cov tsos mob ntawm hluav taws xob / mechanical faults:

Yog hais tias lub solenoid valve tsis qhib, lub cav yuav tsis pib txhua.

Diagnostic fault codes (DTCs) muaj feem xyuam rau injector Circuit Court tsis ua hauj lwm lossis kev txhaj tshuaj kom muaj nuj nqis/sib npaug.

 

 

Qhov kev txiav txim siab los kho lossis hloov cov roj injectors nyob ntawm qhov tsis yog ntawm cov txheej txheem, tab sis kuj yog kev lag luam. Thov xav txog cov hauv qab no:

Cov cuab yeej siv lub neej thiab tus nqi: Rau cov khoom siv tshiab lossis siab dua- cov khoom muaj nqis xws li CAT 320D excavator, kev nqis peev rau cov khoom siv tshiab, txhim khu kev qha tuaj yeem tiv thaiv cov khoom muag khoom muag thiab tiv thaiv lub sijhawm poob rau yav tom ntej. Rau cov cuab yeej qub uas tsis muaj nqi seem, siab -cov tshuaj kho kom zoo dua qub tuaj yeem yog qhov tsim nyog.

Kho thiab hloov cov nqi: Sib piv cov nqi ntawm cov kws tshaj lij kho cov tshuaj txhaj tshuaj thiab cov tshuaj txhaj tshuaj tshiab. Yog tias tus nqi kho dua tshiab tshaj 60-70% ntawm tus nqi ntawm cov khoom tshiab, ces qhov kev lees paub thiab kev thaj yeeb ntawm lub siab muab los ntawm cov tshuaj txhaj tshuaj tshiab feem ntau ua rau lawv muaj txiaj ntsig dua.

 

 

Cov ntsiab lus no feem ntau siv sib hloov, tab sis tuaj yeem sawv cev rau qib kev pabcuam sib txawv:

Kev kho dua tshiab / Kho: Qhov no feem ntau txhais tau hais tias lub tshuab txhaj tshuaj tau raug ntxuav, kuaj, thiab cov ntsaws ruaj ruaj sab nraud tau hloov. Tshwj tsis yog tias ib qho tseem ceeb sab hauv pom tau tias yog qhov tsis raug, nws yuav tsis raug hloov.

Remanufacturing: Qhov no txhais tau hais tias muaj txheej txheem ntau dua qhov twg cov tshuaj txhaj tshuaj yog disassembled mus rau cov khoom tseem ceeb, ntxuav, hnav cov khoom yog hloov nrog cov tshiab, thiab rov kho dua rau cov qauv kev ua tau zoo (feem ntau yog cov qauv tsim khoom qub).

Txawm hais tias remanufactured injectors tej zaum yuav yog ib qho kev xaiv zoo, nws yog ib qho tseem ceeb uas yuav tau yuav lawv los ntawm tus neeg muag khoom muaj koob npe thiab kev tshaj lij. Rau cov neeg siv uas nrhiav kev paub tseeb, kev yuav ib lub hom phiaj -cov tshuaj txhaj tshuaj tshiab uas ua tau raws li lub Hoobkas tshwj xeeb tuaj yeem tshem tawm txhua qhov kev txhawj xeeb txog qhov zoo ntawm cov khoom siv sab hauv lossis qhov nruj ntawm cov txheej txheem rov ua dua.

 

 

Thaum kawg, lo lus teb rau lo lus nug, "Puas tau roj injectors kho?" tsis yog ib qho -size- haum-tag nrho. Thaum ntxuav thiab rov tsim dua tshiab muaj peev xwm ua tau nyob rau qee kis, rau cov cav diesel tseem ceeb -tshwj xeeb tshaj yog nyob rau hauv siab- cov khoom siv tau zoo xws li Kab ntsig excavators thiab loaders- qhov kev nyab xeeb tshaj plaws thiab zoo tshaj plaws - kev xaiv ua tau zoo feem ntau yog rau nruab ib lub hom phiaj - tshiab, siab {{9.}} zoo tshaj plaws

Xaiv ib qho kev tivthaiv zoo li CAT 326-4756 roj injector ua kom koj tau txais cov khoom tsim los rau cov khoom siv thiab cov qauv ntsuas uas xav tau los ntawm koj lub cav.
