adBlue® test
(®= sau npe lag luam ntawm Verband der Automobilindustrie eV (VDA).)
AdBlue®, tseem hu ua DEF (Diesel Exhaust Fluid) los yog AUS32, yog siab -purity 32.5% urea aqueous tov siv nyob rau hauv SCR (Selective Catalytic Reduction) systems ntawm niaj hnub diesel tsheb, tsheb npav thiab tawm - txoj kev machinery. Nws lub luag haujlwm tseem ceeb yog los hloov cov pa phem NOx rau hauv cov pa tsis muaj nitrogen thiab dej vapor, pab cov tsheb ua tau raws li Euro 4, Euro 5 thiab Euro 6 emission cov cai.
Txawm li cas los xij, ntau tus tswv nkoj thiab cov kws tshaj lij kev cob qhia tau saib dhau ib qho tseem ceeb: tsis yog txhua tus AdBlue® ntawm lub khw ua tau raws li ISO 22241 cov lus qhia. Siv diluted, contaminated los yog fake AdBlue® yuav ua rau SCR injector clogging, catalyst lom, cav fais fab derating, emission test tsis ua hauj lwm thiab cov nqi kho loj. Qhov no yog vim li cas AdBlue® kev xeem tsis tu ncua yog ib qho yuav tsum tau rau kev saib xyuas lub nkoj, khaws cia ntau thiab kev tshuaj xyuas cov khoom siv raw.
Yam khoom twg AdBlue® kuaj npog?
Cov cim tseem ceeb rau kev sim AdBlue® yog urea concentration thiab hlau impurity cov ntsiab lus.
ISO 22241 tus qauv yuav tsum muaj urea pawg ntawm 31.8% ~ 33.2%, nrog rau tus nqi zoo tagnrho ntawm 32.5%. Yog tias qhov concentration tsawg dhau, NOx tshem tawm efficiency poob; yog tias nws siab dhau lawm, crystallisation tuaj yeem tshwm sim, thaiv qhov kev txhaj tshuaj nozzle.
Hlau impurities xws li calcium, hlau, tooj liab, thiab lwm yam., muaj kev phom sij heev, thiab tshaj qhov txwv yuav ua rau SCR catalyst mus tas li. Lwm cov khoom kuaj ntsuas muaj xws li refractive index, ntom, biuret, aldehydes, alkalinity, thiab insoluble teeb meem.
Cov kev sim AdBlue® feem ntau
1. Kev ntsuam xyuas sai (ntawm -kev tshuaj ntsuam xyuas qhov chaw)
Portable AdBlue® refractometer yog cov cuab yeej siv dav tshaj plaws rau AdBlue® concentration test. Nws nyeem refractive index thiab converts tus nqi ncaj qha mus rau urea feem pua hauv vib nas this. Digital refractometers nrog tsis siv neeg kub them nyiaj muab kev nyeem ntawv ruaj khov thiab nrov hauv kev cob qhia, chaw nres tsheb roj thiab cov chaw nres tsheb.
AdBlue® xeem strips yog lwm yam tsawg - kev xaiv tus nqi rau kev tshuaj ntsuam ntxhib.
NEWBLUE Metals Quick Test Kit Rau AUS32/AdBlue® txoj kev tshawb nrhiav tshiab tuaj yeem txiav txim siab sai thiab meej seb puas muaj cov hlau ion muaj pes tsawg leeg hauv AdBlue® Liquid/AUS 32/AUS 40/DEF/Urea Solution/Urea Liquid yog tsim nyog, tsis tas yuav muaj cov cuab yeej siv, nrog kev ua haujlwm yooj yim thiab tus nqi siab- zoo
2. Kev kuaj tag nrho AdBlue® kuaj
AdBlue® kev xeem tsis yog ib qho kev xaiv them nyiaj ntxiv. Nws yog kev tiv thaiv kev saib xyuas uas tiv thaiv koj lub SCR system thiab zam kev poob qis. Txawm hais tias koj khiav lub tsheb thauj khoom, kho rhiav lossis AdBlue® cov chaw tsim khoom, kev kuaj DEF tsis tu ncua nrog cov cuab yeej tsim nyog yuav pab ua kom lub tsheb emissions - ua raws thiab txuas ntxiv lub neej kev pab cuam ntawm SCR Cheebtsam.
Muaj ob txoj hauv kev los sim AdBlue® / urea daws. Cov kev xeem hauv chav kuaj muaj kev tso cai ntau dua thiab raug, tab sis lawv tsis raws sijhawm. Cov neeg siv ntawm AdBlue® tsis tuaj yeem tos rau kev kuaj sim ua ntej siv nws, yog li ntawm - qhov kev sim sai sai yog qhov ua tau zoo dua thiab tuaj yeem txheeb xyuas qhov tsis zoo - zoo AdBlue® / urea daws ntawm qhov chaw.
Thaum twg koj yuav tsum khiav AdBlue® xeem?
- Ua ntej kev yuav khoom ntau thiab ntau lub tank filling
- Kev tshuaj xyuas zoo ib ntus rau khaws cia AdBlue® (AdBlue® degrades nyob rau hauv qhov kub thiab txias thiab tshav ntuj ncaj qha)
- Thaum SCR system ua rau cov lej txhaum lossis NOx sensor tswb
- Ua ntej lub tsheb emission tshuaj xyuas
- Xav tias muaj cov khoom cuav los yog muaj paug AdBlue® khoom
Cov lus qhia rau kev ntsuam xyuas AdBlue® txhim khu kev qha
AdBlue® kev xeem tsis yog ib qho kev xaiv them nyiaj ntxiv. Nws yog kev tiv thaiv kev saib xyuas uas tiv thaiv koj lub SCR system thiab zam kev poob qis. Txawm hais tias koj khiav lub tsheb thauj khoom, kho rhiav lossis AdBlue® cov chaw tsim khoom, kev kuaj DEF tsis tu ncua nrog cov cuab yeej tsim nyog yuav pab ua kom lub tsheb emissions - ua raws thiab txuas ntxiv lub neej kev pab cuam ntawm SCR Cheebtsam.
