A. Lub twj tso kua mis urea yog dab tsi thiab nws ua haujlwm li cas?

Suction & Filtration

Lub twj tso kua mis rubDiesel Exhaust Fluid (DEF)los ntawm lub tank.

A limtshem tawm cov kab mob kom tsis txhob txhaws lossis puas tsuaj.

Kev kub siab

Lub twj tso kua mispressurizeslub DEF mus rau qib uas yuav tsum tau (feem ntau ntawm4-9 bar).

Lub siab sensor xyuas kom meej qhov raug xa tuaj.

Txhaj rau hauv Exhaust System

Lub siab DEF yog xa los ntawm cov hoses rhuab mus rau ib qhoinjector (dosing valve)hauv qhov tso pa tawm.

Lub injector sprays ib tug zoo pos huab ntawm DEF rau hauvcov pa cua kubua ntej SCR catalyst.

Tshuaj Reaction hauv SCR Catalyst

HauvSCR catalyst, DEF tawg rau hauvammonia (NH₃)thiabcarbon dioxide (CO₂).

Cov ammonia reacts nrog NOₓ hauv cov pa pa, hloov mus rau hauvTsis muaj nitrogen (N₂) thiab dej vapor (H₂O).

Saib xyuas & Kho

CovECU (Engine Control Unit)tsis tu ncua saib xyuas lub kaw lus thiab kho DEF txhaj tshuaj raws li lub cav load thiab emissions theem.

Vim li cas Urea Pump tseem ceeb?

Txo emissions:Txo cov pa phem NOₓ kom ua tau raws li kev cai ib puag ncig.

Tiv thaiv Engine Derate:Lub twj tso kua mis tsis ua haujlwm tuaj yeem ua rau lub cev muaj zog txo qis.

Cov teeb meem tshwm sim nrog Urea Pumps

Cloggingvim muaj kab mob los yog tsis zoo -DEF.

khovnyob rau hauv qhov txias heev (qee lub twj tso kua mis muaj cua sov).

Hnav thiab kua muagua rau lub siab poob lossis hluav taws xob tsis ua haujlwm.

Siv ibOBD (Ntawm -Board Diagnostics) scannernyeem cov lej yuam kev.

Yog tias lub twj tso kua mis ua haujlwm tsis raug, hloov nws nrog OEM lossis siab - chav tsev zoo tom qab muag.

Tsawg DEF Siab

Ua rau:Leaks, tsis muaj zog twj tso kua mis, faulty siab sensor.

Cov tsos mob:DEF noj tsawg dhau, txo efficiency, xyuas lub cav lub teeb.

Kev daws:

Tshawb xyuas DEFhoses thiab sealsrau xau.

Kuaj covsiab sensorthiab hloov yog tias tsim nyog.

Yog tias lub twj tso kua mis tsis muaj zog, xav txog kev hloov nws.

Tsis yog DEF Concentration

Ua rau:DEF diluted nrog dej los yog dej tas sij hawm.

Cov tsos mob:Kev txo qis NOₓ tsis zoo, cov lus ceeb toom.

Kev daws:

Ib txwm sivtshiab, siab -zoo DEF(32.5% urea, 67.5% deionized dej).

Khaws DEF kom zoo kom tsis txhob muaj kab mob.

 

C. Cov lus qhia rau urea twj tso kua mis yog dab tsi?

Urea Pump Maintenance Tips

✅ Siv High-Quality DEF- Ib txwm siv DEF uas sib ntsibISO 22241 Kev Tswj Xyuasqauv.
✅ Khaws DEF Tank Clean- Tiv thaiv kom tsis txhob muaj kab mob los ntawm kev sib khi lub hau kom nruj.
✅ Tshawb xyuas qhov System tsis tu ncua- Tshawb xyuas cov dej xau, tawg, thiab cov lej ceeb toom.
✅ Tsis txhob khiav ntawm qhov khoob- Cia lub DEF tank khiav qhuav tuaj yeem ua rau lub twj tso kua mis puas.
✅ Kev npaj lub caij ntuj no- Xyuas kom cov cua sov ua haujlwm hauv cov huab cua txias.
✅ Kev siv OBD Scanner-Siv ibOBD-II scannerlos saib xyuas qhov system ua haujlwm.
