DEUTZ Mechanical Unit Pump 04286791 – Precision Fuel Delivery For Series 2013/2014 Cav

CovDEUTZ 04286791 mechanical unit twj tso kua misyog ib tug precision -engineered roj txhaj tshuaj tivthaiv tsim tshwj xeeb rau DEUTZ Series 2013/2014 diesel powerplants. Ua haujlwm ntawmmechanical jerk-pump txoj cai, chav tsev injector no xa cov ntsuas qhov tseeb, siab - siab roj pulses ncaj qha rau txhua lub tog raj kheej- ywj pheej ntawm kev cuam tshuam hluav taws xob. Tsis zoo li cov - kev tsheb ciav hlau uas tso siab rau lub hauv nruab nrab siab -siab accumulator thiab solenoid-actuated injectors, 04286791 siv lub cam-tsav plunger mechanism uas tsim kom muaj kev txhaj tshuaj.hauv qhov, ntawm qhov khoom xa tuaj. Qhov kev txiav txim siab tsis ncaj ncees no muab kev rov ua dua tshiab thiab ua kom yooj yim rau kev daws teeb meem hauv thaj chaw uas cov khoom siv hluav taws xob kuaj xyuas tsis muaj.

Txhua lub twj tso kua mis yog calibrated rauDEUTZ Hoobkas khiav specifications, xyuas kom lub sijhawm txhaj tshuaj raug nyob rau hauv± 0.5℃crankshaft kaum sab xisthiab volumetric sib xws ntawm txhua lub tog raj kheej. Qhov tshwm sim yog sib npaug combustion, txo cov pa roj cua kub (EGT), thiab cov khoom siv hluav taws xob ruaj khov nyob rau hauv qhov sib txawv ntawm lub voj voog thauj khoom -los ntawm excavator hydraulic surges mus rau lub tshuab hluav taws xob teeb theem -load txheej xwm.

Qhov no naj npawb04286791ua haujlwm ncaj qha hloov pauv rau DEUTZ cov tsev neeg hauv qab no:

1. Cam-Txoj Kev Ua Raws Li Cov Menyuam Bearing Upgrade

04286791 suav nrog ibtxhim kho koob- cov menyuam cam raws linrog ib tug hardened steel txheej nplhaib, txo kev sib txhuam los ntawm kwv yees li8–12%piv rau yav dhau los bushing - hom tsim. Qhov no txhais tau ncaj qha rau qis tsav torque xav tau los ntawm lub camshaft thiab txuas ntxiv cov menyuam lub neej nyob rau hauv siab -kev ua haujlwm nrawm nrawm (kuaj rau2, 500+ teevntawm 80% load).

2. Anti-Polishing Nplhaib (APR) Kev koom ua ke

Nyob rau hauv lub plunger chim, ib tug microscopically texturedanti- polishing nplhaibminimizes abrasive hnav los ntawm cov roj- cov khoom uas ua rau, tswj plunger- mus rau - chim tshem tawm hauv3-5 micronstshaj 5,000 teev ua haujlwm. Qhov no tiv thaiv kev txhaj tshuaj zoo ib yam thiab ncua kev ua haujlwm tsis zoo uas feem ntau pom nrog tus qauv chrome-plated plungers.

3. Fuel Temperature Compensation

Tsis zoo li kev hloov pauv yooj yim, chav tsev no nta aua - nyob rau hauv roj kub sensor chaw nres nkoj(M8 × 1 xov) uas, thaum ua ke nrog ib qho kev xaiv thermistor, ua rau lub sijhawm hloov kho ntawm tus tswv xeev txuas - ib qho kev sib txuas ntawm kev sib txuas ntawm cov cuab yeej cuab tam qub nrog cov kev soj ntsuam ntse ntse.

4. Txias -Pib Optimization

Lub twj tso kua mispib caij nplooj ntoos hlav preloadyog Hoobkas- teem kom xa 15% roj ntau dhau thaum cranking (qis dua 150 rpm), txo cov pa luam yeeb dawb ntev los ntawmmus txog 40%ntawm ambient kub ntawm -15℃thaum ua ke nrog DEUTZ glow-plug systems.

Ua ntej-Nruab Kos Npe:
✔️ Tshawb xyuas covcamshaft loberau cov qhab nia - hloov yog hnav tshaj 0.15 hli
✔️ Tshawb xyuastappet clearance(0.30-0.35 hli)
✔️ Prime lub twj tso kua mis nrog huv diesel ntawm lubtes- primer leverkom txog thaum huab cua- roj dawb tawm ntawm lub valve

Calibration Protocol (tsis muaj lub rooj zaum kuaj):

📌 Lub rooj zaum calibration yog ib txwm pom zoo - tab sis cov txheej txheem saum toj no muab kev pabcuam thaub qab thaum kev nkag mus rau kev cob qhia raug txwv.

Q1: Lub 04286791 puas tuaj yeem hloov 04170123 qub yam tsis hloov lub sijhawm sijhawm?
Yog, ob qho tib si sib npaugcamshaft tsav geometry(12- hniav coupling, 45℃siab lub kaum sab xis). Txawm li cas los xij, rov- sij hawm yog yuav tsum tau vim hais tias lub plunger nqa nkhaus txawv me ntsis - siv lub dial-indicator txoj kev piav qhia saum toj no los teeb lub sij hawm.

Q2: Cov tsos mob dab tsi qhia tias lub twj tso kua mis no tsis ua haujlwm, thiab cov teeb meem injector nozzle?
Ib lub twj tso kua mis tsis ua haujlwm feem ntau tsim tawmirregular khobuas hloov nrog lub cav ceev (tsis zoo li nozzle hnav, uas ua rau tsis muaj hluav taws xob tsis zoo thaum tsis ua haujlwm). Kuj xyuas cov dej ntws tawm - yog tias cov roj dribbles tsis tu ncua los ntawm cov pa tawm - tawm ntawm kab, lub plunger tshem tawm tau dhau qhov kev zam.

Q3: Puas yog lub twj tso kua mis no siv tau nrog biodiesel blends (B20 / B30)?
Yog, cov ntaub ntawv foob yogFKM (Viton®) qib, kuaj rau B30 compatibility mus txog 60℃roj kub. Rau kev sib xyaw ntau dua (B50–B100), peb pom zoo kom hloov kho lub valve O-rings rauHNBR- muaj nyias.

Q4: Kuv yuav txheeb xyuas cov twj cuav li cas 04286791?
Authentic units muaj alaser -engraved DEUTZ logontawm lub mounting flange nrog 7-tus cim batch code pib nrog "WK". Cov cuav feem ntau omit covmicro-etchingntawm lub plunger crown - siv 10 × loupe los txheeb xyuas.

Q5: Dab tsi yog qhov kev pabcuam xav tau rau lub twj tso kua mis no hauv lub tshuab hluav taws xob- teeb daim ntawv thov?
Ntawm qhov tsis tu ncua 1,500 rpm / 75% load, lub twj tso kua mis feem ntau tshaj8,000 teevua ntej plunger hnav cuam tshuam rau kev ua tau zoo - kwv yees li ob npaug ntawm lub sijhawm rau kev ua liaj ua teb mobile daim ntawv thov vim yog lub zog thermal cycling.

Q6: Kuv puas tuaj yeem haum rau phau ntawv nres cable rau lub twj tso kua mis no yog tias lub kaw lus hluav taws xob solenoid tsis ua haujlwm?
04286791 vaj tse suav nrog amechanical nres lever tus thawj coj(tsis siv nyob rau hauv Hoobkas configuration). Ib qho khoom siv thoob ntiaj teb Bowden cable tuaj yeem rov kho dua siv M6 threaded qhov muab - sab laj nrog qhov txuas ntxiv.
