Bosch 120 Series Injector Armature Stroke & Dynamic Lift Measurement Gauge - Sib nqus-Stabilized Dial Indicator Rau Precision Flow Consistency

Lub electromagnetic armature stroke nyob rau hauv ib tug Bosch 120-series common rail injector tsis yog ib tug taag txhua yam tas li; Nws yog qhov nyob ntev uas hloov nrog kub, hnav, thiab hydraulic siab. Qhov no stroke-feem ntau yog nyob nruab nrab ntawm 0.08 mm thiab 0.22 mm rau lub valve tswj- ncaj qha tswj cov kev txhaj tshuaj shaping, pilot kom muaj nuj nqis stability, thiab rov qab roj ntim. Pa dial gauges, clamped rau arbitrary nto, qhia parallax thiab vibration yuam kev uas yooj yim tshaj ± 15 μm kam rau ua qhov rais yuav tsum tau rau Euro VI emissions ua raws. Peb qhov tshwj xeeb ntsuas ntsuas suite ua ke lub caij nplooj ntoos hlav-loaded plunge sojntsuam nrog ib tug dual-scale dial qhia, ruaj los ntawm ib tug haib magnetic stabilizer puag uas cais kev nyeem ntawv los ntawm lub cav thaiv kev vibrations thiab tus neeg teb xov tooj tes tshee. Nws txawv ntawm qhov zoo li mob stroke (armature ntawm so, coil de-energized) thiab dynamic nqa (armature txav nyob rau hauv simulated PWM tsav)- muab ob lub ntsiab lus ywj pheej uas ua ke kwv yees kev ua haujlwm ntawm lub tshuab ua ntej nws rov nruab. Qhov no tsis yog qhov ntsuas qhov tob dav dav; nws yog lub hom phiaj-calibrated diagnostic cuab tam uas txhais cov neeg kho tshuab hloov mus rau hauv actionable fuel delivery intelligence.

Static stroke yog txoj kab tawm ntawm lub armature los ntawm nws qhov chaw zaum tag nrho mus rau nws cov neeg kho tshuab nres thaum lub solenoid tsis muaj zog. Peb gauge siv lub hardened carbide tip uas hu rau lub armature saum npoo los ntawm lub injector lub nozzle tuav cov txiv ntseej nkag mus rau qhov chaw nres nkoj. Lub hauv paus sib nqus stabilizer (tuav lub zog> 800 N) mounts ncaj qha mus rau lub cev injector, kom ntseeg tau tias lub dial taw qhia axis tseem coaxial nrog lub armature bore - tshem tawm qhov yuam kev angular uas skew nyeem txog li 20 μm. Lub ntsej muag loj loj (52 hli txoj kab uas hla) muab qhov loj me ntawm 0-2 hli nrog 0.001 hli sib faib thiab ib qho kev sib tw siab siab thib ob uas cim hauv thaj chaw ntsuab / daj / liab. Ib tug built-in fine-adjustment ntsia hlau tso cai xoom-tsim tawm tsam ib tug calibrated master block (suav nrog), them nyiaj rau tej yam hnav ris tsho. Lub zog zoo li qub rau Bosch 120 injectors (piv txwv li, 0 445 120 xxx, 0 445 120 yyy) yog lub Hoobkas tshwj xeeb ntawm 0.12 ± 0.02 hli; kev nyeem ntawv sab nraum qhov no qhia tau hais tias lub rooj zaum yaig lossis daig armature qhia.

Dynamic nqa replicates lub armature qhov tseeb txav thaum tus neeg tsav tsheb injector muab lub ncov-thiab-tuav tam sim no waveform (feem ntau 18 A ncov, 6 A tuav, ntawm 200 Hz). Peb lub cuab yeej suav nrog cov khoom siv hluav taws xob sab nraud uas tsim cov teeb liab programmable PWM (10-500 Hz, 5-25 A) los txhawb lub zog solenoid thaum lub ntsuas ntsuas tsis tu ncua cov ntaub ntawv hloov chaw. Lub dynamic nqa yog ib txwm me ntsis loj dua li zoo li qub stroke vim inertial over-mus ncig thiab sib nqus saturation cuam tshuam -ib qho tseem ceeb parameter uas cuam tshuam lub kaw ncua ncua sij hawm thiab tom ntej pilot txhaj stability. Lub dial indicator's built-in peak-hold mechanism captures qhov siab tshaj plaws hloov chaw thaum lub sij hawm excitation mem tes, tso saib nws nyob rau hauv ib tug thib ob koob liab liab koob uas locks kom txog thaum pib dua. Rau Bosch 120 series, dynamic nqa feem ntau tshaj li static stroke los ntawm 0.010-0.025 hli; ib qho kev sib txawv dhau lub qhov rais no qhia tias lub caij nplooj ntoos hlav tsis muaj zog lossis kev ua si ntau dhau. Lub module tseem muaj kev hloov pauv lub luag haujlwm uas simulates qhov sib txawv ntawm lub cav nrawm, tso cai rau cov kws tshaj lij los saib seb kev hloov pauv li cas nrog RPM-ib qho txiaj ntsig zoo rau kev tsis txaus siab tsis sib xws.

Lub hauv paus kev tsim kho tshiab yog lub rooj sib nqus hlau nplaum-ib sintered neodymium hlau nplaum array nrog peb-point roj hmab-isolated mounting phaj uas adheres khov kho rau lub injector lub cylindrical lub cev. Tsis zoo li clamp-on stands uas hloov nyob rau hauv lub zog ntawm cable, no magnetic puag muab ib tug nruj, vibration-attenuated siv. Lub dial taw qhia tau raug tshem tawm ntawm ob txhais caj npab nrog kev sib txhuam xauv, tso cai rau qhov chaw nyob hauv peb axes yam tsis poob xoom. Ib theem siab ntawm tus ntsuj plig ua kom muaj kev sib haum xeeb, thaum lub tshuab hluav taws xob sib nqus (ON / OFF) tso cai rau kev hloov pauv sai yam tsis muaj demagnetising lub workpiece. Peb tau sim cov stabilizer tiv thaiv tus qauv rhiav sawv ntsug thiab kaw 63% txo qhov kev nyeem ntawv hloov pauv (los ntawm ± 0.008 hli mus rau ± 0.003 hli) nyob rau hauv simulated cav vibration (50 Hz, 2 g). Qhov kev ruaj ntseg no ncaj qha txhais mus rau kev ntseeg siab dhau / tsis ua tiav kev txiav txim siab, tshwj xeeb tshaj yog thaum ntsuas qhov nruj 0.15 hli dynamic nqa qhov pib uas cais cov neeg siv khoom siv tau los ntawm tus neeg sib tw los hloov.

Qhov ntsuas ntsuas no tau lees paub rau tag nrho Bosch 120 injector kab, suav nrog:

CRIN 2(0 445 120 001 rau 120 099)

CRIN 3(0 445 120 100 rau 120 199)

CRIN 4(0 445 120 200 rau 120 299)
thiab tag nrho cov sib npaug sib npaug (Delphi, Denso) uas sib koom tib yam 10-mm armature txoj kab uas hla thiab M10 × 1 mounting xov.

Q1: Dab tsi yog lub hauv paus ua rau kev nyeem ntawv zoo li qub uas qis dua lub Hoobkas txwv?
A: Feem ntau, qhov no yog vim kev yaig ntawm lub armature nres phaj lossis cov khib nyiab hauv qab armature, uas tiv thaiv tag nrho lub rooj zaum ntawm lub valve. Peb qhov ntsuas qhov kev daws teeb meem zoo qhia qhov kev yaig thaum ntxov; ib qho kev nyeem hauv qab 0.10 hli qhia tias yuav tsum tau nres lub phaj hloov lossis lub taub ntim lub taub ntim rov qab.

Q2: Vim li cas thiaj li nqa lub cev muaj zog qee zaum dhau qhov nqa zoo li qub los ntawm ntau dua 0.03 hli, txawm tias nyob rau ntawm lub tshuab tshiab?
A: Ntau dhau dynamic overshoot cov ntsiab lus kom tsis muaj zog armature rov qab caij nplooj ntoos hlav lossis ntau dhau hydraulic damping. Xyuas lub caij nplooj ntoos hlav quab yuam nrog peb xaiv lub caij nplooj ntoos hlav tester; Yog hais tias tsis nyob rau hauv spec, tshuaj xyuas cov armature qhia rau hnav. Overshoot tshaj 0.03 hli tuaj yeem ua rau muaj qhov tsis zoo ntawm kev tsav tsheb thiab lub suab nrov combustion.

Q3: Qhov ntsuas no puas tuaj yeem siv rau ntawm Bosch 130 lossis 160 series injectors?
A: Kev sojntsuam taub thiab mounting geometry yog tshwj xeeb rau 10-mm armature bore ntawm 120 series. Peb muab cov khoom siv cais rau 130 (12 mm) thiab 160 (14 mm) tsev neeg. Txawm li cas los xij, qhov sib nqus stabilizer thiab excitation module yog universal thiab tuaj yeem hloov kho nrog cov kev xaiv sojntsuam adapters.

Q4: Ntev npaum li cas yuav tsum tau ntsuas qhov ntsuas qhov ntsuas?
A: Peb pom zoo kom rov ua dua txhua xyoo lossis tom qab txhua 500 lub voj voog ntsuas. Cov block tswv suav nrog tso cai rau xoom-check txhua hnub; yog tias qhov xoom drifts los ntawm ntau tshaj 0.002 hli, xa rov qab qhov ntsuas rau peb qhov chaw pabcuam kev hloov kho -tsis txhob sim hloov cov ntsia hlau sab hauv vim nws tsis muaj daim ntawv pov thawj calibration.

Q5: Puas yog qhov kub thiab txias cuam tshuam rau qhov ntsuas qhov ntsuas dynamic?
A: Yog- tooj liab kuj nce nrog qhov kub thiab txias, txo qhov siab kawg tam sim no thiab yog li lub zog sib nqus. Peb excitation module muaj xws li qhov kub thiab txias feature uas kho PWM lub luag hauj lwm voj voog raws li ambient thermistor nyeem (ua rau hauv lub module). Xyuas kom lub injector nyob rau hauv chav tsev kub (20 ± 3 degree) rau kev sib piv benchmark.

Q6: Kuv puas tuaj yeem siv cov cuab yeej no los ntsuas qhov nqa ntawm tus tsav valve (tswj valve) es tsis yog lub ntsiab armature?
A: Cov khoom siv no yog tsim los rau lub ntsiab solenoid armature, tsis yog tus tsav valve (uas yog hydraulically actuated). Rau pilot nqa, peb muab ib qho kev ntsuas siab-siab stroke ntsuas. Txawm li cas los xij, lub hauv paus sib nqus stabilizer tuaj yeem rov qab siv tau nrog cov khoom siv ntawd, ua rau nws muaj peev xwm hloov pauv.
