Nws yog ib qho tseem ceeb uas yuav tau ua cov kev saib xyuas ntawm urea tank

Lub sijhawm no, peb coj cov kev siv hluav taws xob uas siv hluav taws xob urea ua piv txwv los qhia ob peb txoj hauv kev yooj yim los daws cov urea system tsis ua haujlwm thiab ceev faj.

● Kev txhaum 1: Pipeline crystallization

Fault analysis:Pipeline crystallization yog ib qho teeb meem feem ntau ntsib los ntawm cov neeg tsav tsheb. Txhua zaus lub tsheb pib thiab kaw, yuav muaj urea seem nyob rau hauv lub twj tso kua mis urea thiab cov kav dej. Yog li ntawd, thaum lub tsheb raug kaw, lub twj tso kua mis urea yuav ua haujlwm ntawm kev ntxuav cov urea seem. Txawm li cas los xij, nyob rau hauv qhov kub thiab txias ib puag ncig lossis thaum cov cua kub tsis zoo, cov urea seem yuav tsis raug ntxuav kom huv si. Nyob rau tib lub sijhawm, nws yuav pib txhaws.

Kev daws yooj yim:HauvThaum muaj xwm txheej ceev, koj tuaj yeem siv cov dej kub npau npau kom sov cov kav dej. Cov neeg tsav tsheb uas muaj kev txawj tes zoo tuaj yeem tshem cov kav dej thiab ntxuav lawv ntawm tes. Tsis tas li ntawd, cov neeg tsav tsheb yuav tsum tau xyuam xim tsis txhob tua lub hwj chim tam sim ntawd thaum lub cav raug kaw. Tos kom txog thaum cov kav dej tsis huv ua ntej muab nws tua.

● Kev txhaum 2: Nozzle blockage

Fault analysis:Thaum siv cov urea tsis zoo los yog tsis zoo urea pom, impurities nyob rau hauv urea accumulates ntawm lub nozzle, ua rau lub urea txhaj system ua hauj lwm txawv txav.

Kev daws yooj yim:Muab cov urea nozzle tso rau hauv lub lauj kaub thiab boil rau ib ntus kom txog thaum cov khoom thaiv raug tshem tawm. Nco ntsoov tsis txhob ntxuav nws manually nrog cov khoom ntse.

● Kev txhaum 3: Cov khoom lim yog txhaws

Kev soj ntsuam txhaum: Tsis yog lub nozzle nkaus xwb, tab sis kuj yog cov khoom lim siv los lim impurities hauv urea tuaj yeem txhaws. Nws cov nyhuv lim kuj tseem cuam tshuam ncaj qha rau kev huv ntawm urea ntawm lub nozzle. Thaum lub caij lim yog txhaws los yog ua tsis tiav, qhov teeb meem feem ntau yog sib koom ua ke.

Kev daws yooj yim: Hloov cov lim lim thiab tshem tawm nws rau kev ntxuav phau ntawv thaum muaj xwm txheej ceev.

● Kev txhaum 4: Sensor tsis ua hauj lwm

Fault analysis:Muaj ntau lub sensors nyob rau hauv lub tank urea, xws li kua theem sensors thiab kub sensors. Cov sensors no yog siv los txheeb xyuas cov xwm txheej ua haujlwm thiab cov xwm txheej ntawm urea system. Thaum lub sensor tsis ua haujlwm, urea system yuav tsis tuaj yeem txau rau hauv SCR system ib txwm.

Kev daws yooj yim:Txij li thaum lub sensor yog ib tug technically complex ntaus ntawv, thaum nws ua tsis tau tejyam, nws tsuas yog hloov tau.
