BOSCH DCR Injector Service Master Kit - Piezo & Solenoid Valve Calibration Solution Rau Common Rail Systems

Niaj hnub nimno txoj kev tsheb ciav hlau ua haujlwm ntawm qhov siab tshaj 2,200 bar. Nyob rau theem no, qhov sib txawv ntawm qhov kev txhaj tshuaj dhau mus thiab qhov tsis ua tiav tsis ntsuas hauv microns- nws tau ntsuas hauvmicrosecondsntawm valve nqa thiabfractional Newtonhloov nyob rau hauv lub caij nplooj ntoos hlav preload. CovBosch Diesel Injector Service Kittsis yog ib phau ntawm wrenches thiab seals; nws yog qhov chaw nres tsheb metrology portable tsim los rov pib dua lub tshuab nco txog siab - coj cov tshuaj tiv thaiv rov qab rau Euro 6 kam rau ua.

Feem ntau cov kev cob qhia tso siab rau ECU flash cov ntaub ntawv los kwv yees kev noj qab haus huv. Cov khoom siv no tig mus ua haujlwm. Es tsis txhob tso siab rau lub tsheb qhov kev kuaj mob onboard, koj ntsuas lub cevactuator stroke, koob nqa hysteresis, thiabrov qab ntws tawmntawm lub rooj ntev zaum.

Stroke Measurement Precision:Cov khoom siv suav nrog lub siab - daws teeb meem dial gauge nrog 0.01mm division, tshwj xeeb rau Bosch injector clamping bolts. Qhov no tso cai rau cov kws tshaj lij los xyuas qhov tseebarmature stroketom qab shim hloov - tus nqi tseem ceeb uas cuam tshuam ncaj qha nrog kev txhaj tshuaj kom muaj nuj nqis sib txawv ntawm kev sim tshuaj txhaj tshuaj.

Leakage Test Adapters:Tsis zoo li cov khoom siv thoob ntiaj teb, Bosch- tshwj xeeb adapters foob tiv thaiv qhov siab - kev sib txuas siab thiab xa rov qab cov chaw nres nkoj ib txhij, ua kom muajstatic siab decay testtsis tshem lub injector los ntawm lub tuav fixture. Qhov no txheeb xyuas lub plunger / chim hnav ua ntej nws ua rau P0087 code.

Cov khoom siv sab hauv layout ua raws akho cov kab ke ua haujlwm, tsis yog qhov loj me xwb. Sab saum toj txheej muaj covnozzle lapping cov cuab yeejthiabkoob lift gauges, thaum lub hauv qab txheej tsev lubshim xaiv setsthiabtorque adaptersrau cov txiv ntoo tuav.

Daim Ntawv Thov Matrix:Xws li yog ib lub laser -engraved siv daim ntawv (tsis yog ntawv) uas correlates ntsuas clearance nrog yuav tsum tau shim thickness, accounting rau thermal expansion coefficients ntawm lub1.4835 stainless hlausiv hauv Euro 5/6 nozzles. Qhov no txo ​​qhov kev sim - thiab - yuam kev lub sijhawm sib dhos los ntawm 40%.

Retaining Nut Socket:Cov khoom siv nta nyias -phab ntsa, hardened steel socket nrog atorque-limiting dab tshostxhawm rau tiv thaiv dhau - zawm lub taub hau lub cev sab sauv - ib qho kev ua tsis tau zoo uas cuam tshuam rau lub rooj zaum tswj lub valve.

Txhua Bosch injector variant (los ntawm cov laus CRIN mus rau tam sim no CRSN piezo hom) muaj qhov tshwj xeeb "roj rov qab" geometry. Cov khoom siv no suav nrogdual- sealing O- nplhaib teeb(FKM thiab HT-ACM) los tswj ob qho tib si biodiesel blends thiab siab - sulfur fuels pom nyob rau hauv cov lag luam tawm tshiab.

Pilot Valve Lift Tool:Ib lub siab sib nqus sawv ntsug tso cai rau rov ntsuas qhov ntsuastswj piston nqatsis tshem tag nrho lub valve los ua ke. Qhov no yog qhov tseem ceeb vim tias hnav hauv cheeb tsam no ua rau "clatter" thiab tsis ua haujlwm tsis sib xws, feem ntau raug kuaj pom tias yog qhov teeb meem camshaft.

Flow Bench Adapters:Lub adapter teeb tso cai rau kev sib txuas ncaj qha rau Bosch EPS 200 lossis Hartridge AVM2 kuaj cov rooj zaum, kom ntseeg tau tias cov khoom kho kho koj txhais ncaj qha rau hauv kev kho.µl / mob strokeqhov tseem ceeb ntawm daim ntawv xeem.

Piezo injectors degrade txawv ntawm solenoid sawv daws yuav. Covpiezo pawgpoob capacitance dhau sijhawm, hloov qhov qhib ncua sijhawm. Cov khoom siv no muab ib qhopulse signal generatorthiab breakout cables los ntsuam xyuas cov pawg hluav taws xob teb thaum nws yog mechanically disassembled.

Capacitance Tester:Ib qho ua tau los ntawm -hauv cov yam ntxwv ntawm tus ntsuas tso cai rau koj los ntsuas cov pawg qhov kev poob qis- yog tias nws tshaj 15% ntawm tus nqi nominal, koj paub tias kev kho tsis muaj txiaj ntsig yam tsis tau hloov hluav taws xob actuator, txuag koj tus nqi rov qab.

Q1: Cov khoom siv no puas tuaj yeem ua haujlwm tau qhov tseeb Bosch CRSN piezo injectors nrog lub "X" variant nozzle, los yog nws txwv rau cov laus solenoid hom?
A: Cov khoom siv tau ua tiav nrog cov tsev neeg solenoid (CRIN) thiab piezo (CRSN). Lub tshuab hluav taws xob pulse thiab capacitance tester yog tsim tshwj xeeb rau piezo stacks, thaum lub tshuab ntsuas ntsuas npog solenoid armature strokes. Txawm li cas los xij, rau qhov "X" nozzle variants nrog asymmetric spray qhov, xyuas kom meej tias koj siv qhov tshwj xeeb nruab nrab mandrel cim "X-Type" suav nrog hauv txheej.

Q2: Kuv yuav ua li cas tiv thaiv kev puas tsuaj rau lub ntsej muag tswj lub rooj zaum thaum siv lub cuab yeej lapping?
A: Cov cuab yeej lapping suav nrog muaj lub caij nplooj ntoos hlav -loaded siab limiter. Nws siv lub siab tshaj plaws axial quab yuam ntawm 12 N, tiv thaiv tus neeg teb xov tooj los ntawm "kev khawb" rau hauv lub rooj zaum. Ib txwm siv cov lus qhia lapping bushing kom tswj tau qhov perpendicularity.

Q3: Daim npav xaiv shim hais txog "thermal expansion"-qhov no puas txhais tau tias kuv yuav tsum tau preheat lub injector lub cev ua ntej ntsuas clearance?
A: Tsis yog. Daim npav muab tus nqi kho kom raug (CF) tus nqi. Koj ntsuas kev tshem tawm ntawm chav tsev kub (20 degree), ces muab faib los ntawm CF rau cov khoom tshwj xeeb (1.4835). Qhov no ua rau koj ua haujlwm tshem tawm ntawm 120 degree, xyuas kom koj tsis txhob dhau -shim thiab ua rau rab koob khi thaum kub.

Q4: Dab tsi yog qhov siab tshaj plaws kev pab cuam lub neej (tus naj npawb ntawm kev kho) rau lub zog torque - txwv lub qhov (socket) ua ntej nws qaug zog?
A: Lub qhov (socket) raug ntsuas rau 2,500 lub voj voog nruj ntawm 80 Nm. Peb pom zoo kom kuaj xyuas cov splines sab hauv rau hnav tom qab txhua 500 lub voj voog uas siv cov khoom siv mus / tsis muaj- mus, vim tias cov splines tsis sib xws tuaj yeem hloov pauv tsis sib xws rau cov txiv ntoo tuav.

Q5: Yog tias kuv siv cov khoom siv no rau ntawm Euro 3 injector, cov ntaub ntawv sealing tshiab (HT-ACM) puas yuav ua rau muaj teeb meem nrog cov roj qib qub?
A: HT-ACM cov ntsaws ruaj ruaj yog rov qab sib xws. Lawv yeej muaj peev xwm tiv taus ntau dua cov ntsiab lus sulfur pom hauv cov roj siv nrog cov cav qub. Txawm li cas los xij, xyuas kom tseeb tias koj siv qhov tseeb O- lub nplhaib loj- cov khoom siv suav nrog cov xim - coded daim ntawv kom phim cov xim xim (ntsuab rau Euro 3/4, Xiav rau Euro 5/6).

Q6: Yuav ua li cas lub tshuab hluav taws xob suav nrog 200V + ncov voltages xav tau rau kev kuaj piezo injector yam tsis muaj kev puas tsuaj rau chav tsev?
A: Lub tshuab hluav taws xob suav nrog cov kab hluav taws xob tawm hluav taws xob uas txwv tam sim no rau<1.5A. It steps up voltage to 220V but with a soft-start ramp to prevent piezoelectric crystal shock. The output is fully isolated, so no ground loops affect the measurement.
