C9 Common Rail Injector Rebuild Kit - Precision Overhaul Teeb Rau Kab ntsig C9 / C9.3 Cav

Nyob rau hauv lub high-stakes ib puag ncig ntawm hnyav-lub luag hauj lwm diesel combustion, cov roj injector ua hauj lwm ntawm kev sib tshuam ntawm huab hydraulic siab, ceev electromechanical actuation, thiab aggressive roj chemistry. Rau Caterpillar's C9 thiab C9.3 cav cov tsev neeg-cov neeg ua haujlwm hauv excavators, cov tsheb thauj khoom nruj, thiab kev ua liaj ua teb sib xyaw ua ke-injector kev ua tau zoo degradation feem ntau tsis yooj yim thaum xub thawj: me ntsis nce hauv roj noj, ib qho tsis tshua pom kev tsis pom kev, lossis cov pa luam yeeb dub hauv qab sudden load. Sab laug tsis kho, cov tsos mob no nce mus rau hauv cov nqi poob qis, tsis ua tiav cov kev sim emissions, thiab txawm tias muaj kev puas tsuaj rau lub tog raj kheej.

CovC9 Common Rail Injector Rebuild Kityog engineered los cuam tshuam no downward kauv. Tsis yog hloov tag nrho cov kev sib koom ua ke ntawm cov twj tso kua mis-cov lus qhia peev-intensive- cov txheej txheem kho dua tshiab no muab tag nrho cov khoom sib khi tseem ceeb, cov nplhaib rov qab, lub tshuab ntxhua khaub ncaws caij nplooj ntoos hlav, thiab tswj-valve gaskets uas yuav tsum tau rov qab ua haujlwm injector rau ze-OEM kam rau ua. Txhua qhov sib xyaw ua ke yog sib npaug rau C9 qhov tshwj xeeb injector architecture, uas ua haujlwm ntawm kev tsheb ciav hlau siab mus txog2,000 barthiab txhaj cov xwm txheej luv luv li150 microseconds.

Hauv qab no yog tag nrho cov ntaub ntawv pov thawj cov lej rau covC9 Injector Kho Cov Khoom Siv, teeb tsa hauv lub rooj 6-kem huv si rau kev siv ceev: 235-5261 10R-9002 254-4330 267-3361 293-4072 328-2573 387-9436 20R-8068 557-7637 10R-7221 20R-8968 236-0957 267-3710 293-4073 20R-8065 328-2580 387-9437 20R-8062 573-4231 20R-8846 10R-7222 20R-9433 238-8092 254-4340 267-3717 328-2576 387-9431 387-9438 577-7633 10R-7223 242-0857 265-8106 267-9722 387-9432 387-9433 387-9439 20R-8061 10R-2828 11R-1582 245-3516 20R-8060 266-4446 293-4071 293-4074 553-2592 10R-4764 20R-1917 267-3360 387-9434 328-2574 557-7634 10R-4844 20R-8064 –

Ntau qhov kev muag khoom tom qab tau nres ntawm O-rings sab nraud -ib "cov khoom siv foob" uas tsuas yog pom qhov xau. Kev noj qab haus huv tiag tiag, txawm li cas los xij, nyob ntawm kev ncaj ncees sab hauv: lub siab-siab roj qhov chaw, lub servo-hydraulic tswj Circuit Court, thiab cov nozzle koob qhia txhua yam yuav tsum tau muaj meej sealing thiab clearance tswj. Cov khoom siv kho dua tshiab C9 no mus dhau qhov kho qhov chaw los ntawm suav nrog:

Fluoroelastomer O-ringsnrog Shore A hardness ntawm 90 ± 5, ntsuas rau kev raug txuas mus rau ultra-low-sulfur diesel thiab biodiesel blends (B20).

PTFE thaub qab ringsuas tiv thaiv extrusion nyob rau hauv cyclic siab spikes tshaj 2,200 bar.

Reinforced tswj-valve gasketsuas tuav qhov sib npaug me me ntawm kev ua haujlwm siab thiab rov qab ntim ntim.

Pre-lubricated qia ntsaws ruaj ruajuas txo kev sib txhuam thaum lub sij hawm txhaj tshuaj lub lab-cycle-ib-hnub ua haujlwm.

Cov Cheebtsam no tsis yog generic-lawv yog kev cai-molded rau Caterpillar qhov ntev specifications, nrog rau qhov tseem ceeb sealing diameters tuav rau± 0.02 hlithiab nto roughness hauv qab noRa 0.8 µm.

Lub C9 cav platform yog siv nyob rau hauv ntau yam sectors, thiab cov khoom siv kho dua tshiab no muaj ntau yam sib npaug:

Kev Tsim Kho & Mining:Excavators (xws li, 330D, 336D, 345D), log loaders, thiab off-highway tsheb

Ua liaj ua teb:Cov tsheb laij teb loj, sib sau ua ke, thiab tus kheej-propelled sprayers

Industrial & Marine:Cov khoom siv hluav taws xob, cov chaw nres tsheb, thiab cov chaw pabcuam marine fais fab

Nyob rau hauv txhua daim ntawv thov, cov kev tsheb ciav hlau feem ntau xav tau kev ua haujlwm tsis muaj qhov tsis zoo kom ua tau raws li Tier 4 Interim / Theem IIIB emissions qauv. Cov khoom siv no pab tswj kev ua raws li qhov tsis tau them nqi ntawm cov tshuaj txhaj tshuaj tshiab.

Thaum cov khoom siv tau muab nrog txhua yam khoom siv tsim nyog, kev vam meej hinges ntawm kev qhuab qhia los ua ke:

Kev huv yog tsis-negotiable:Ib qho particle> 10 µm tuaj yeem cuam tshuam lub servo valve. Siv cov ntaub so tsis muaj lint-dawb thiab cov tshuaj ntxuav tu tshwj xeeb.

Lubricate O-rings nrog huv si diesel los yog roj sib dhos-qhuav installation ua rau shear puas.

Tighten injector tuav-down bolts rau qhov tseeb torque(feem ntau 45–50 N·m rau C9, txheeb xyuas ib phau ntawv cav).

Ua ib qho kev xeem tawmTom qab kev teeb tsa: ntsuas cov roj rov qab ntim rau ib lub tog raj kheej; qhov sib txawv> 15% qhia txog cov teeb meem zaum.

Prime lub roj systemua ntej pib kom tsis txhob qhuav-khiav kev puas tsuaj rau lub twj tso kua mis siab thiab cov tshuaj txhaj tshuaj.

Q1: Cov khoom siv no puas haum rau C9 thiab C9.3 cav variants?
Yog lawm, lub tshuab nqus tsev twj tso kua mis yog zoo ib yam ntawm C9 thiab C9.3 rau cov txheej txheem kev tsheb ciav hlau uas tau them los ntawm cov lej no. Txawm li cas los xij, ib txwm paub tseeb tias koj tus lej txhaj tshuaj tshwj xeeb sib dhos (xws li 20R-8065 lossis 387-9433) tawm tsam lub rooj sib haum-C9.3 Acert qauv yuav siv cov khoom siv sib txawv ntawm lub taub hau, uas cov khoom siv no nyob.

Q2: Kuv tuaj yeem qhia tau li cas yog tias kuv cov tshuaj txhaj tshuaj yuav tsum tau hloov kho tag nrho piv rau cov ntsaws ruaj ruaj sab nraud?
Yog tias koj pom cov roj to nyob ib ncig ntawm lub cev lub cev lossis cov roj rov qab, cov khoom siv foob yuav txaus. Tab sis yog tias koj muaj kev khiav haujlwm hnyav, siv roj ntau ntxiv, lossis cov pa luam yeeb dub, kev hnav sab hauv yuav zoo li - cov khoom siv kho dua tshiab yog qhov kev xaiv raug vim tias nws rov ua dua txhua qhov kev sib khi sab hauv thiab tswj-valve gaskets.

Q3: Dab tsi yog qhov kev pab cuam lub neej tom qab rov tsim kho nrog cov khoom siv no?
Kev teeb tsa kom raug, lub tshuab rov tsim kho feem ntau xa 80-90% ntawm lub neej ntawm OEM injector tshiab -feem ntau 8,000-10,000 teev ua haujlwm- nyob ntawm seb cov roj zoo thiab kev saib xyuas. Kev hloov pauv roj-filter tsis tu ncua thiab kev tso dej cais tawm yog qhov tseem ceeb rau kev ua kom lub neej ntev.

Q4: Kuv puas tuaj yeem hloov ib qho tshuaj txhaj nrog cov khoom siv no, lossis kuv yuav tsum ua txhua lub tog raj kheej?
Peb pom zoo kom rov tsim kho tag nrho cov injectors ntawm tib lub cav tib lub sijhawm kom ntseeg tau tias cov roj sib npaug. Yog tias muaj kev txwv tsis pub siv nyiaj, tsawg kawg yog rov tsim dua ob lub tsev txhab nyiaj (lossis khub) kom tsis txhob muaj hluav taws xob tsis sib xws thiab muaj peev xwm tsim teeb meem EGR / DPF.

Q5: Cov khoom siv puas suav nrog lub taub ntim tshuaj lossis lub solenoid valve?
Tsis yog. Qhov no yog cov khoom siv kho / sealing - nws muaj tag nrho cov gaskets, O-rings, rov qab rings, thiab cov khoom me me. Nozzles thiab solenoids yog cov khoom sib cais thiab yuav tsum tau kuaj xyuas; yog tias puas lawm, lawv yuav tsum tau hloov ib tus zuj zus.

Q6: Yuav ua li cas kuv phim kuv lub cav serial tooj rau cov khoom siv raug?
Kab ntsig siv 7-tus lej cav serial ua ntej (piv txwv li, C9S, C9T). Thaum cov khoom siv no npog feem ntau ntawm C9 hom-rail injectors, peb qhia koj kom nkag mus rau koj lub cav serial tooj thiab injector tus lej rau hauv peb cov cuab yeej siv hla (muaj nyob hauv peb lub vev xaib) rau 100% kev pom zoo.

 

Txhawm rau ua kom koj qhov kev yuav khoom tau yooj yim thiab yooj yim, peb muab ntau yam kev xaiv them nyiaj ruaj ntseg:

Peb nyob ntawm no los ua kom koj cov txheej txheem xaj kev txhawj xeeb-dawb - xaiv txoj kev them nyiaj uas ua haujlwm zoo tshaj rau koj!
