🔄 Urea Pump Hloov Lub Sij Hawm

🔹 A urea twj feem ntau kav ntev li 200,000 - 400,000 km (120,000 - 250,000 mais)nyob rau hauv ib txwm ua hauj lwm tej yam kev mob.
🔹 Yog tias lub twj tso kua mis ua tsis tau ua ntej no mais,cov tsos mobsuav nrog:

Tsawg DEF siab (Cov lej yuam kevP20E8, P204F).

DEF system ceeb toom ntawm lub dashboard.

Txo NOₓ kev hloov dua siab tshiab ua rau muaj kev tso tawm ntau ntxiv.

Crystallization buildup ua rau blockages.

🚀 Lub tswv yim los txuas ntxiv Urea Pump Life

🔹 Siv siab - zoo DEF (ISO 22241-certified)tiv thaiv kev kis kab mob.
🔹 Tsis txhob cia lub tsheb ntevnyob rau hauv qhov chaw txias yam tsis siv lub tshuab cua sov DEF.
🔹 Ntxuav lub system nrog dej deionizedsij hawm los tiv thaiv crystallization.

🛠️ 3. Yuav Pab Tau Urea Pump li cas (Step-by-Step)

🚀 A. Tshawb xyuas lub Pump & System

1️⃣ Tua lub cav & disconnect lub roj teeb.
2️⃣ Tshawb xyuas cov dej xaunyob ib ncig ntawm lub twj tso kua mis, hoses, thiab injector.
3️⃣ Tshawb xyuas cov lej yuam kevsiv OBD-II scanner.
4️⃣ Ntsuas DEF siab(yuav tsum4-9 bar).

🚀 B. Hloov lub lim dej DEF

🔹 Nrhiav qhovDEF lim (feem ntau nyob ze ntawm lub twj tso kua mis lossis hauv lub tank DEF).
🔹 Tshem cov lim qub thiabnruab ib qho tshiabraws li cov neeg tsim khoom cov lus qhia.
🔹 Prime lub kaw lus thiab tshem tawm cov lej yuam kev uas khaws cia.

🚀 C. Ntxuav lub System (Tshem tawm Crystallization)

1️⃣ Tshem lub twj tso kua mis & kabnrogdej sov deionized(tsis yog dej cawv).
2️⃣ Yog tias crystallization hnyav, siv aDEF tshuaj ntxuav.
