VTO-G2050L54 Solenoid Common Rail Injector - Siab- Teb Chaws Rau Nruab Nrab- Lub Luag Haujlwm Ua Lag Luam

Nruab nrab ntawm lub teeb-lub luag hauj lwm injector thiab cov hnyav-flow industrial unit yog ib ntu uas ua rau feem ntau ntawm cov tsheb thauj khoom hauv nroog, cov tsheb npav hauv nroog, thiab cov tshuab ua liaj ua teb- cov cav uas xav tau cov lus teb ceev ceev, tsis muaj zog, thiab huv combustion thoob plaws qhov dav dav. Lub VTO-G2050L54 yog lub tshuab hluav taws xob solenoid-actuated common rail injector engineered rau hauv nruab nrab hauv av, xa cov dej ntws zoo li qub.1,120 ml / min ntawm 100 barnrog rau qhov qhib ncua ntawm tsuas yog 0.40 ms-ib lub sijhawm teb ceev tshaj plaws hauv nws chav kawm. Qhov kev ceev no tau ua tiav los ntawm cov khoom siv qis qis (2.9 grams) thiab lub zog sib nqus hluav taws xob ua haujlwm siab uas txo cov sijhawm rub tawm yam tsis muaj qhov nce siab tam sim no. Qhov tshwm sim yog ib qho kev txhaj tshuaj uas tswj xyuas cov neeg tsav tsheb ntau npaum li cas txawm tias nyob rau ntawm lub cav ceev (txog 4,000 rpm), ua rau nws tshwj xeeb tshaj yog haum rau cov ntawv thov sib txawv-ceev qhov twg ECU xav tau kev sib xyaw ua ke los ntawm qhov tsis ua haujlwm rau lub zog ntsuas. Rau cov neeg tsav nkoj uas saib xyuas qhov tseem ceeb ntawm kev tsav tsheb thiab kev tso pa tawm raws li tsis muaj qhov nyuaj ntawm piezo systems, VTO-G2050L54 muab cov pov thawj solenoid tov nrog ze-piezo teb.

VTO-G2050L54 muab cov dej ntws zoo li qub1,120 ml / min (± 2.5%)ntawm a7-qhov nozzle nrog 0.24 mm orificesthiab 148℃suav nrog lub kaum ntse ntse. Qhov no configuration yog optimized rau lub combustion tais feem ntau ntawm 4- mus rau 7-liter cav nrog nruab nrab swirl ratios (1.8-2.2).

Txau cov ntaub ntawv ntawm 1,600 bar, 2.0 ms energising:

Sauter Mean Dia: 17.2 µm

Kev nkag mus ntev ntawm 1.0 ms tom qab SOI: 43 hli

Lub kaum sab xis ntawm lub kaum sab xis: ± 1.2℃thoob plaws txhua qhov

Flow linearity yuam kev: <2.5% hla 300-1,800 bar

Shot-to-shot variation: CoV < 1.6%

Txoj kev khiav linearity yog qhov tseem ceeb tshwj xeeb rau cov tshuab ua haujlwm nruab nrab uas nquag mus ncig ntawm qhov tsis ua haujlwm thiab ib nrab ntawm cov khoom thauj -ib qho tsis-linear injector yuav ua rau muaj kev ntxhov siab lossis nce siab thaum lub sijhawm nrawm. VTO-G2050L54's linearity yuam kev yog khaws cia qis dua 2.5%, kom ntseeg tau tias ECU daim ntawv qhia lub sijhawm tseem muaj tseeb yam tsis tas yuav tsum tau them nyiaj nyob.

VTO-G2050L54 siv tus qauv CRI-2 mounting hneev taw (M12 × 1.5 inlet, 45 mm clamp pitch, 6.0 mm leak-off connector) thiab yog hloov ncaj qha rau:

Cummins ISB 6.7 TSI(2007-2018, 200-325 hp)

Cummins QSB 6.7(Tier 3 / Theem IIIA off-highway)

John Deere 4045/6068(PowerTech E, 4.5L thiab 6.8L kev ua liaj ua teb)

Perkins 1106D / 1204E(Industrial thiab genset)

FPT N45 / N67(IVECO / CNH lub tshuab ua haujlwm nruab nrab)

Isuzu 6HK1 / 6HH1 TSI(cov tsheb thauj khoom nruab nrab thiab excavator)

Mitsubishi 4N14 / 4N15 TSI(qee lub teeb coj mus muag variants)

Lub injector kuj sib xws nrog ntau yamTom qab kev lag luam ECU hloov khoom dua tshiabuas yuav tsum tau ceev ceev teb solenoid. Nws yogtsis yog suitable for piezo‑based systems, high‑flow (>1,200 ml / min) muaj cav, lossis cov neeg caij tsheb siv hauv qab 2.0 litres.

Solenoid injectors feem ntau qeeb qeeb thaum roj kub nce - cov coil tsis kam nce, txo qhov rub tawm tam sim no. VTO-G2050L54 hais txog qhov no nrog atooj liab-alloy windinguas muaj qhov kub coefficient qis dua (0.0039 /℃piv rau 0.0043 /℃rau tus qauv tooj liab), ua kom qhov kev tiv thaiv tsis pub dhau 6% dhau ntawm −30℃rau +140℃ntau yam.

Ntsuas thermal ua haujlwm:

Ua hauj lwm ntawm -30 degree: 0.54 Ω

Kev ua haujlwm ntawm 20 degree: 0.67 Ω

Ua hauj lwm ntawm 140 degree: 0.80 Ω

Qhib ncua sij hawm nce (20℃→ 140 degree): 0.06 ms

Qhib ncua sij hawm nce (-30℃→ 20 degree): 0.04 ms

Kev ruaj ntseg thermal txhais tau hais tias ECU txoj kev hloov pauv tsis tas yuav them nyiaj rau lub sijhawm hloov pauv ntawm qhov kub thiab txias ntau zaus - tus neeg txhaj tshuaj coj tus cwj pwm tsis tu ncua los ntawm Canadian lub caij ntuj no mus rau Middle Eastern lub caij ntuj sov.

VTO-G2050L54 yog tsim los ua haujlwm nrog ob qho tib sincov-thiab-tuavthiabsaturated-tsavECU architectures. Nws cov nominal kuj (0.67 Ω) thiab inductance (1.12 mH) poob nyob rau hauv lub neej ntawd tsav teeb tsa ntawm:

Bosch EDC16 / EDC17

Denso HP3 / HP4

Delphi E3 / E4

Continental SID 301 / SID 305

Lub injector tsis xav tau tus kheej trim code- nws qhov kev kam rau siab ntawm ± 2.5% yog nyob rau hauv qhov kev hloov pauv ntawm cov tswj hwm no. Txawm li cas los xij, rov pib dua lub tog raj kheej-qhov sib npaug tom qab kev teeb tsa tau pom zoo kom txo lub sijhawm kawm los ntawm 50 mus rau kwv yees li 10 lub voj voog.

Q1: Kuv ntsia VTO-G2050L54 tab sis lub cav xav tias qeeb - qhov txawv ntawm qhov kuv xav tau. Yuav ua li cas yuam kev?
Ua ntej, xyuas cov roj lim- cov lim lim yuav txo cov kev tsheb ciav hlau siab, thiab ECU txo lub sijhawm txhaj tshuaj kom them nyiaj. Qhov thib ob, ntsuas qhov kev tiv thaiv kab mob; yog tias nws tshaj 0.3 Ω ib ceg, lub injector tsis tau txais tam sim no thiab nws qhov qhib ncua nce. Thib peb, xyuas kom meej tias lub tog raj kheej-sib npaug hloov pauv tau rov pib dua- yog tias tsis muaj qhov no, ECU tuaj yeem siv qhov tsis zoo los ntawm cov tshuaj txhaj tshuaj yav dhau los.

Q2: Cov tshuaj txhaj tshuaj ceev ceev yog qhov zoo rau cov lus teb throttle, tab sis kuv hnov ​​​​ib lub suab "nias" ntawm idle- puas yog qhov qub?
Ib qho txawv, sib luag nias yog lub suab ntawm lub zog solenoid. Nws yuav tsum tau mloog tab sis tsis intrusive. Yog tias qhov nias hnyav los yog nrog kev vibration, lub clamp bolts yuav xoob, cia lub injector resonate tawm tsam lub tog raj kheej taub hau. Re-torque mus rau 10 N·m + 90℃. Yog tias qhov nias tsis raug, ECU yuav muaj teeb meem nrog tus tsav tsheb tam sim no - xyuas cov software hloov tshiab.

Q3: Kuv tab tom khiav lub cav ntawm B30 biodiesel. Puas yog tus qauv teb ceev ceev yuav tsum tau hloov kho?
Biodiesel's viscosity siab dua ua rau cov dej ntws los ntawm kev tswj lub valve, ua rau qhov qhib ncua sij hawm kwv yees li 0.02 ms ntawm B30-me me txaus uas ECU lub sijhawm hloov kho yuav them rov qab. Txawm li cas los xij, qhov nce viscosity kuj tseem txo cov koob kaw nrawm, yog li qhov kev kaw qeeb yuav nce mus rau 0.20 ms (los ntawm 0.18 ms). Qhov no tseem nyob hauv qhov txwv tau. Rau B50 thiab saum toj no, peb pom zoo kom luv luv lub sijhawm kev pabcuam thiab siv cov roj zoo sensor rau ECU nyiaj.

Q4: Lub cav muaj qhov "rail siab overshoot" txhaum tom qab kuv hloov tag nrho rau lub injectors. Cov lus teb ceev tuaj yeem yog qhov ua rau?
Thaum koj txo qhov qhib ncua sij hawm thoob plaws txhua lub tog raj kheej, tag nrho cov roj tau kos thaum lub sij hawm pib txhaj tshuaj nce me ntsis - lub twj tso kua mis yuav tsis tuaj yeem teb sai txaus, ua rau muaj kev kub ntxhov. Qhov no feem ntau yog daws los ntawm kev ua lub twj tso kua mis hloov kho dua tshiab (muaj nyob rau hauv cov cuab yeej kuaj mob feem ntau), uas recalibrate lub twj tso kua mis lub siab tswj valve rau cov lus teb injector tshiab.

Q5: Cov tshuaj no puas tuaj yeem siv rau hauv daim ntawv thov siab siab (tshaj 3,000 m)?
Lub injector nws tus kheej yog qhov siab-agnostic- nws teb rau lub tsheb ciav hlau siab thiab lub zog teeb liab. Txawm li cas los xij, nyob rau qhov siab siab, qis cua ceev txo lub tog raj kheej siab, uas txo qis qhov backpressure ntawm lub nozzle. Qhov no tuaj yeem nce qhov txhaj tshuaj ntau npaum li 0.5-1% ntawm 1,000 m. ECU daim ntawv qhia qhov siab qhov siab yuav tsum kho qhov no; yog tias tsis yog, yuav tsum muaj kev hloov kho me me rail siab.

Q6: Dab tsi yog txoj kev pom zoo rau kev ntsuas qhov qhib ncua sij hawm hauv thaj teb?
Txoj kev ua tau zoo tshaj plaws yog los saib xyuas lub injector tam sim no waveform nrog oscilloscope thiab clamp-on ammeter. Qhov qhib ncua sij hawm yog lub sij hawm los ntawm qhov pib ntawm tam sim no nce (rub-hauv) mus rau qhov inflection point qhov twg armature txav (pom zoo li ib tug me me poob rau hauv cov kab tam sim no). Kev noj qab haus huv VTO-G2050L54 qhia qhov poob ntawm 0.38-0.42 ms tom qab pib ntawm tus tsav tsheb hais kom ua. Yog tias lub dip ncua ntev tshaj 0.45 ms, xyuas cov xaim lossis cov twj tso kua mis hydraulic.
