T402742 Perkins roj injector - Hnav-Adaptive Clearance & Multi-Pulse Fidelity Rau Euro IV-VI Commercial Diesels

Feem ntau phau ntawv qhia kev pabcuam piav qhia txog lub tshuab txhaj tshuaj los ntawm nws tus nqi zoo li qub thiab qhov nozzle qhov. CovT402742siv txoj hauv kev sib txawv: nws cov geometry sab hauv yog tsim los kom them nyiaj rau kev nthuav dav thermal thiab kev coj ua zoo, tswj kom muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov hydraulic ntawm cov khoom siv lub neej. Es tsis txhob sib ntaus sib tua, qhov no injector harnesses nws - tus tswj piston thiab koob qhia feature ib tug graded clearance uas nqaim me ntsis raws li qhov kub thiab txias, offsetting viscosity poob thiab khaws cia lub sij hawm txhaj tshuaj stability. Qhov no txhais tau hais tias ECU qhov kev teeb tsa ua ntej pulse widths tseem siv tau txawm tias tom qab 500 000 km, txo qhov xav tau ntawm kev kho kom zoo.

Solenoid kauj: kuj 0.88 Ω ± 0.04 Ω (24 V), optimized rau ceev tam sim no nce nrog tsawg inductive kickback.

Tswj valve: ob-theem pilot tsim nrog lub rooj zaum steel pob, txo qis sab hauv los ntawm 18% piv rau hom rooj zaum.

Koob & qhia: Cov khub sib tw nrog lub npe diametral clearance ntawm 6 µm, nthuav mus rau tsuas yog 8 µm ntawm 120℃- ua kom ntseeg tau los ntawm cov hlau tsis tshua muaj kev nthuav dav.

Nozzle: 5 qhov × Ø0.200 hli, lub kaum sab xis 150 degree, tailored rau lub tog raj kheej piston hauv 10 mus rau 13-liter cav.

Dab tsi txawv T402742 yog nwshydraulic damping chamberintegrated rau lub caij nplooj ntoos hlav lub rooj zaum. Lub chamber no absorbs siab oscillations los ntawm txoj kev tsheb ciav hlau, stabilizing lub koob kaw suab thiab tshem tawm cov kev txhaj tshuaj thib ob uas feem ntau plague multi-pulse tswv yim.

T402742 yog tsim rauM14×1.5xov cu a46 hli projection, haum:

DAF MX-11 / MX-13 (Euro IV-VI)

Tus txiv neej D26 / D28 series

Scania DC13 (nrog Bosch CPN twj)

Suav HD platforms: Weichai WP10H, WP12, Yuchai YC6K

Qhov tseem ceeb mounting txoj cai: Siv a28 N·m + 60 degreezawm ib ntus - tsis yog ib qho nqi torque. Cov txheej txheem no ua kom lub zog clamping sib npaug sib npaug thoob plaws lub cev lub cev, kom tsis txhob muaj kev cuam tshuam ntawm lub tshuab hluav taws xob solenoid armature air-gap (tseem ceeb rau kev sib nqus sib nqus).

Tsis zoo li ntau cov tshuaj niaj hnub no uas yuam kom koj nkag mus rau IQA lossis QR-code kho, T402742 ua haujlwmmechanical flow-balancing methodthaum lub sij hawm tsim khoom. Txhua chav tsev yog pre-matched mus rau ib tug nominal txaus kam rau ua ntawm ± 1.2%, uas yog nruj txaus rau feem ntau OEM ECUs los ntawm lawv adaptive kev kawm loops (xws li, Bosch EDC17 los yog Continental SID). Rau kev cob qhia, qhov no tshem tawm qhov xav tau ntawm cov cuab yeej kuaj xyuas kim coding - tsuas yog nruab, ua tus txheej txheem, thiab cia ECU tus kheej hloov kho dua thawj 10 km.

Lub nozzle lub qhov npoo yog micro-puab nrog cov txheej txheem abrasive-flow, uas txo cov pa roj carbon adhesion. Thaum lub sij hawm txhua qhov kev txhaj tshuaj, lub dav hlau roj siab tshaj plaws tsim lub tshuab nqus tsev hauv zos uas rub cov khoom tawm ntawm lub qhov nkag mus - ib qho kev tu tus kheej tsis tu ncua uas ua rau lub sijhawm ua haujlwm ntev. Ua ke nrog CrN txheej ntawm kev tswj piston, T402742 tiv taus cov ntsiab lus ntawm sulfur mus txog 500 ppm thiab biodiesel blends (B30 kuaj) yam tsis muaj qhov cuam tshuam loj los yog galling.

Q1: T402742 tsis muaj IQA code - puas yuav lub cav khiav ntxhib yog tias kuv muab nws nrog cov tshuaj qub qub los ntawm cov khoom sib txawv?
Txij li thaum lub chav tsev yog mechanically balanced rau ± 1.2%, sib tov nrog lwm T402742 los ntawm ib tug sib txawv batch yog siv tau raws li ntev raws li ob leeg nyob rau hauv tib lub ndlwg chav kawm ntawv (cim rau ntawm lub thawv). Txawm li cas los xij, tsis txhob sib xyaw nrog cov lej qub uas muaj cov qauv hydraulic sib txawv - ib txwm hloov txhua lub tog raj kheej nrog tib tus qauv rau kev pom zoo lub tog raj kheej-rau-lub tog raj kheej sib npaug.

Q2: Kuv tuaj yeem qhia tau li cas yog tias lub tshuab txhaj tshuaj sab hauv damping chamber ua tsis tiav?
Koj yuav hnov ​​​​lub suab nrov ntawm cov hlau nplaum ntawm qhov nruab nrab ntawm qhov load, nrog rau lub zog me ntsis hauv lub cav ceev. Qhov no qhia tau hais tias lub caij nplooj ntoos hlav damping tau nkees. Ib qho yooj yim rov-leak kuaj yuav pom cov xau ntau tshaj 25 ml / 30 s - feem ntau nws yuav tsum qis dua 20 ml. Hloov chav tsev yog tias ob qho kev tshwm sim tshwm sim.

Q3: Qhov kev txhaj tshuaj no puas tuaj yeem ua tau zoo sib xyaw biodiesel tsis tu ncua?
Yog - CrN txheej thiab micro-puab qhov tiv thaiv corrosion thiab deposit build-up. Rau B30 lossis qis dua, kev ntxuav yog pom zoo txhua txhua 250 000 km; rau B100, txo rau 150 000 km. Ib txwm siv cov roj-dej cais tawm los tiv thaiv lub valve.

Q4: Dab tsi yog qhov laj thawj ntawm kev txuas ntxiv cranking tom qab txhim kho T402742?
Feem ntau cov cua daig rau hauv txoj kab siab. Vim tias qhov tshuaj txhaj no muaj qhov tso tawm sab hauv qis heev, nws tsis tuaj yeem los ntshav sai li cov khoom hnav. Crank lub cav rau 10 vib nas this, tos 20 vib nas this, rov ua dua 3-4 zaug, thiab xyuas kom lub tsheb ciav hlau siab siab tshaj 25 MPa ua ntej sim pib - qhov no tshem tawm huab cua zoo.

Q5: Puas yog 28 N·m + 60℃txoj cai siv rau txhua hom cav?
Rau M14 threads, yog - tab sis ib txwm txheeb xyuas lub tog raj kheej lub taub hau lub taub ntim qhov tob. Yog tias lub tes tsho clamping hnav, koj yuav tsum tau ntxiv ib qho calibrated shim. Peb pom zoo kom siv lub tshuab ntxhua khaub ncaws tooj liab tshiab thiab lub tshuab hluav taws xob siab txhua zaus; cov tshuab ntxhua khaub ncaws qub tuaj yeem txo lub zog clamping thiab ua rau lub tshuab tshuab.

Q6: Kuv yuav ua li cas thiaj paub meej tias cov tshuaj txhaj tshuaj yam tsis muaj lub rooj zaum kuaj?
Thaum lub rooj zaum ntawm lub rooj zaum ntawm lub cav yog qhov tseeb tshaj plaws, koj tuaj yeem ua qhov "drip test" los ntawm kev tshem lub injector, txuas nws mus rau txoj kev tsheb ciav hlau, thiab ua rau nws nrog cov cuab yeej mem tes. Saib xyuas cov tshuaj tsuag ntawm 80 MPa - T402742 noj qab haus huv ua kom zoo, txawm tias pos huab tsis pom cov kwj deg. Yog tias koj pom cov streaks hnyav lossis cov tee dej, lub nozzle yuav raug thaiv lossis hnav.
