Diesel Injector Roj Injector 5396273 Denso Injector rau Cummins, Pem Hauv Ntej Qag

1. Feem ntau ua txhaum ntawm hluav taws xob tswj lub cav injectors
Qhov tsis ua haujlwm ntawm lub tshuab hluav taws xob tswj lub tshuab hluav taws xob tsis yog tsuas yog ua rau lub zog ruaj khov thiab lub zog ntawm lub cav txo qis, tab sis kuj cuam tshuam rau kev ua haujlwm ntawm lub cav tsheb, uas ua rau txo qis hauv kev ruaj ntseg ntawm lub cav lub zog. Cov kev ua txhaum ntau yog: dripping, tsis raug roj txhaj tshuaj, kev txhaj tshuaj tsis raug cai, thiab lwm yam. Feem ntau, nws yog tshwm sim los ntawm rab koob valve sticking, tsis zoo sealing, lim blockage, coil burning thiab txawv txav teeb liab. Tus nqi ntawm cov roj txhaj los ntawm lub injector thiab qhov sib xws ntawm cov roj muab rau txhua lub tog raj kheej kuj tseem yuav ua rau poob lossis tso tseg cov roj txhaj tshuaj.
Thib ob, kev tshawb pom ntawm cov tshuab hluav taws xob tswj lub cav injectors
1. Kev ntsuas qhov tsis kam ntawm electromagnetic coil ntawm cov roj injector tuaj yeem kuaj pom ntawm lub tsheb, lossis nws tuaj yeem ntsuas tau tom qab tshem tawm. Txoj kev ntsuas thiab tus qauv yog: tshem tawm cov roj injector harness plug, ntsuas qhov kev tiv thaiv ntawm ob lub terminals ntawm cov roj injector nrog ib tug multimeter, lub koom haum txheem yog hais txog 12 ~ 162 (siab impedance hom) los yog 3 ~ 62 (tsawg impedance hom. )
2. Txheeb xyuas qhov hluav taws xob qhov hluav taws xob ntawm lub tshuab hluav taws xob electromagnetic. Lub hwj chim mov voltage ntawm cov roj injector tuaj yeem kuaj nrog tus pointer lossis digital multimeter. Thaum kuaj, thawj zaug unplug ob lub terminals ntawm txhua lub roj injector feem, thiab tom qab ntawd tig rau ntawm qhov hluav taws xob hloov. Yog tias lub cav tseem tsis tuaj yeem pib ib txwm, ces tsuas yog kuaj tau qhov voltage. Cov theem yuav tsum siab tshaj 12V (lub tsheb fais fab mov voltage), thiab qib qis yuav tsum yog 0V. Yog tias lub zog hluav taws xob raug txiav thiab qhov siab thiab qis nruab nrab ntawm ob lub terminals ntawm cov hlua khi thiab lub cav yog xoom, ces cov roj txhaj tshuaj fuse thiab cov roj twj tso kua mis relay yuav tsum tau kuaj xyuas nyias.
