59407500087 Solenoid Common Rail Injector - Siab -Frequency Switching Valve Group rau kev ua kom zoo dua qub

Hauv lub tshuab hluav taws xob niaj hnub no, ECU teeb tsa cov lus txib ntawm millisecond intervals, tab sis tus neeg siv lub peev xwm ua kom ncaj ncees ua cov lus txib no -tshwj xeeb tshaj yog thaum lub sijhawm hloov pauv - nyob ntawm cov lus teb dynamic ntawm lub valve tswj. Lub 59407500087 yog ib qho kev sib txuas ntawm cov hluav taws xob solenoid-actuated common rail injector engineered nrog ib tugsiab -frequency switching valve pawguas xa qhov qhib thiab kaw qeeb ntawm 0.39 ms thiab 0.19 ms raws li- ntawm qhov ceev tshaj plaws hauv nws chav kawm. Cov lus teb ceev ceev no tau ua tiav los ntawm lub teeb yuag armature, lub tshuab hluav taws xob luv luv, thiab qhov zoo tshaj plaws sib nqus Circuit Court uas txo lub sij hawm tsim thiab ua kom tawg ntawm electromagnetic teb. Rau cov cav uas ua haujlwm nyob rau hauv cov xwm txheej nyuaj heev - tsheb thauj mus los hauv nroog, gensets thaum muaj xwm ceev, thiab marine manoeuvring-lub 59407500087 xyuas kom meej tias lub sij hawm txhaj tshuaj tseem muaj tseeb txawm tias lub cav ceev lossis thauj khoom hloov sai, txo cov pa taws thiab tswj kev ua raws li cov pa tawm thaum lub sijhawm nrawm.

59407500087's valve pawg yog tsim los rau kev ua kom sai los ntawm peb lub ntsiab lus tseem ceeb: lub teeb yuag armature (2.75 g), luv luv spool stroke (0.28 mm), thiab high-permeability magnetic core uas saturates sai.

Leak-off connector: 22 N·m.

Hluav taws xob connector:Ntxuav cov pins, siv cov roj dielectric-kev tiv thaiv tuaj yeem ua rau cov lus teb solenoid qeeb.

Tsis tas yuav tsum tau trim code rau feem ntau ntawm ECUs - qhov ± 2.5% ndlwg kam rau ua nyob rau hauv qhov kev hloov ntawm Bosch EDC16/17, Denso HP3/4, thiab Delphi E3/E4 maub los.

Q1: Lub tshuab txhaj tshuaj muaj qhov qhib ncua sijhawm luv luv -qhov no puas yuav tsum tau hloov pauv ECU?
Lub sijhawm qhib luv luv txhais tau hais tias qhov pib txhaj tshuaj tiag tiag yuav tshwm sim ntxov dua li ECU xav tau. Qhov no tuaj yeem cuam tshuam emissions thiab combustion nrov. Feem ntau ECUs muaj qhov hloov kho lub sijhawm hloov pauv uas them rau qhov hloov pauv ntawm cov tshuaj txhaj tshuaj-rau-injector, tab sis yog tias qhov sib txawv tseem ceeb, yuav tsum muaj kev hloov kho calibration. Xyuas nrog koj lub cav calibrator.

Q2: Kuv siv B30 biodiesel. Puas yog qhov hloov pauv ceev tseem ua haujlwm?
Biodiesel lub viscosity siab dua ua rau cov dej ntws los ntawm kev tswj lub valve, uas tuaj yeem ua rau kom qhib ncua sij hawm li ntawm 0.02 ms. Lub 59407500087 qhov kev hloov pauv ceev tau them nyiaj rau qhov no - tag nrho kev ncua tseem qis dua 0.42 ms, uas tseem nrawm dua li cov txheej txheem feem ntau ntawm cov pob zeb hauv av.

Q3: Lub cav muaj qhov yuam kev "siab-ceev" tom qab txhim kho qhov kev txhaj tshuaj no - puas muaj feem xyuam?
Kev hloov pauv ceev tuaj yeem ua rau ECU kuaj pom qhov tawg sai dua li qhov xav tau tam sim no, uas qee qhov ECU txhais tau tias yog qhov txhaum. Qhov no tsis tshua muaj tab sis tuaj yeem tshwm sim nrog qee qhov ECU software versions. Yog tias qhov txhaum tshwm sim, hu rau ECU cov chaw tsim khoom rau kev hloov kho software uas haum rau kev hloov pauv sai dua.

Q4: Lub injector zoo li tsis muaj suab nrov thaum tsis ua haujlwm - puas yog qhov qub?
Fast-switching injectors tsim ib tug sharper click-nws yog lub suab ntawm armature qhib thiab kaw sai dua. Nws yog tus yam ntxwv ntawm tus qauv tsim thiab tsis yog qhov ua rau muaj kev txhawj xeeb. Lub suab nrov yuav tsum zoo ib yam thoob plaws txhua lub tog raj kheej; Yog hais tias ib qho yog nrov nrov, xyuas lub clamp bolt torque.

Q5: Kev hloov pauv sai puas tuaj yeem txo cov roj noj?
Yog lawm. Lub sijhawm txhaj tshuaj meej dua yuav txo cov roj nkim thaum lub sijhawm hloov pauv. Kev txuag roj yog qhov pom tau zoo tshaj plaws hauv kev tsav tsheb hauv nroog, qhov twg lub cav siv ib feem tseem ceeb ntawm nws lub sijhawm nrawm thiab qeeb. Kev txuag yog feem ntau 1-2% hauv kev ua haujlwm sib xyaw.

Q6: Lub cav muaj qhov txhaum "lub tog raj kheej" uas tshwm sim tsuas yog nyob rau ntawm RPM siab xwb- qhov kev hloov pauv sai puas tuaj yeem ua rau nws?
Thaum siab RPM, lub qhov rais txhaj tshuaj yog luv heev, thiab txhua qhov kev hloov pauv hauv kev hloov ceev yuav yog qhov tseem ceeb. 59407500087 qhov kev hloov ceev ceev yuav tsum txo qhov kev pheej hmoo ntawm kev ua haujlwm siab RPM, vim tias cov tshuaj tiv thaiv teb sai dua li cov tshuaj txhaj tshuaj. Yog tias qhov txhaum tshwm sim, tshawb xyuas cov kab hluav taws xob injector -kev tiv thaiv siab hauv cov hlua tuaj yeem ua rau cov lus teb solenoid qeeb, tsis pom zoo hloov pauv sai.
