Nguva yechando mota urea fluid ichaoma?Zvakadini nechando?Iwe unoda kuwedzera antifreeze yakaderera tembiricha urea?
Pakangodonha tembiricha munguva yechando, varidzi vemotokari vazhinji, kunyanya kuchamhembe, vanozonetsekana nezve urea tank yavo inotonhora, ivo vanobvunza kana mota urea ichatonhora, sei kuiomesa nechando, kana kuwedzera muridzi wemba yakaderera tembiricha. urea nemamwe matambudziko, uye vamwe varidzi vemotokari vanotsiva zvakananga iyo yakajairwa urea mhinduro ine urea mhinduro ye -35 ° C, vachifunga kuti izvi zviri nyore, chaizvoizvo, hazvisi.Haingodhuri mari chete asi zvakare inokuvadza zviri nyore hurongwa hwekurapwa kwemotokari.Zvino ngatikudzei pfungwa huru.
Sei kuwedzera urea solution?
Ko kusawedzera kwakaipei?
Iyo inonzi mota urea solution, inozivikanwawo sedhiziri exhaust treatment liquid, inoreva mhinduro yeurea ine urea concentration ye32.5% uye inonyungudutsa yeultra-pure water, uye zvinhu zvayo mbishi urea crystals uye Ultra-pure water.Inoiswa muurea tangi, kana pombi yekupedza ikawanikwa iine nitrogen oxide, tangi yeurea inoburitsa otomatiki iyo urea solution yemotokari, uye maitiro maviri eREDOX anoitika muSCR reaction tank, inogadzira nitrogen isina kusvibiswa uye kubuda kwemvura, kuderedza utsi.
SCR system inoshanda musimboti: Nekufarirwa kwemotokari ina, yenyika shanu, uye kunyange gare gare yenyika nhanhatu, mota urea inogona kunzi yakakosha yekuwedzera SCR, uye zvakare chinhu chakakosha chigadzirwa chemotokari dzedhiziri semarori nemabhazi. kuti isangane nenyika zvishanu nemitanhatu emission standards.
Kusawedzera urea mhinduro kwenguva yakareba, kana kushandisa mvura yakachena kana pombi mvura panzvimbo, zvinokonzeresa kukuvadzwa kukuru kune urea nozzle uye kunyangwe iyo yese post-kurapwa system.Kuziva kuti kutsiva urea nozzle kazhinji zviuru zviuru zveyuan, iyo system yese inoda 30,000 kusvika 50,000 yuan.
Chii chinonzi -35 ℃ mota urea solution?
Iwe unoda kuwedzera yakaderera tembiricha urea mhinduro?
Iyo mota urea solution inotarwa nenyika ina shanu emission standards dzinotanga kutonhora pane yakajairika tembiricha iri pasi -11 ° C. Mumwe nemumwe anogadzira anoshandisa additives (ethanol kana ethylene glycol) kuderedza kutonhora kwenzvimbo yemotokari urea, kuitira kuti vabudirire chinangwa chekudzivirira kutonhora.Zvisinei, iyo ethanol mukuwedzera inopfuta uye inoputika, uye pombi yemoto inoputika iri pakupisa kwepamusoro, kana iyo ethanol concentration yakanyanyisa, inokonzera kukanganisa kwepombi yekupedza.Pasi pemamwe mamiriro ekupisa, ethylene glycol inoburitsa asidhi zvinhu, izvo zvinokonzeresa ngura papombi yekuburitsa uye kukonzera kubuda.Naizvozvo, hapana chikonzero chekushandisa iyo inonzi -35 ° C yemotokari urea mhinduro, uye zvakanyanya kukosha, iyo -35 ° C yemotokari urea mhinduro inenge 40% inodhura kupfuura yakajairwa pamusika.
Urea solution inotonhora munguva yechando here?
Ko kana ndikatonhora?
Urea solution inotonhora munguva yechando here?Ko kana ndikatonhora?Muchokwadi, matambudziko aya, vagadziri vagara vachifunga, kazhinji vanoda antifreeze iyo yekumusoro vhezheni yemotokari SCR system ine urea tank thaw yekudziya basa, kana injini tembiricha yemvura inosvika 60 madhigirii, urea mvura tembiricha yakaderera pane -5 madhigirii. Celsius, kubva papombi yeinjini kuenda kune urea tank injini inotonhorera inovhura kuyerera kwekufamba, kuitira kunyungudutsa urea fluid crystallization murea tank.
Sezvo SCR ichida tembiricha yekuburitsa injini kuti isvike kupfuura 200 ° C kuti ipinde pabasa, urea fluid haizopfapfaidzwa pane yakaderera tembiricha, kuitira kuti ipe nguva yakakwana yekunyungudika crystallized urea fluid.
Naizvozvo, hapana chikonzero chekunetseka kana iyo urea solution ichatonhora, uye kuti ungaita sei mushure mechando.Mukuwedzera, kunyange munzvimbo dzinotonhora zvikuru, hapana chikonzero chekuwedzera iyo inonzi yakaderera-kupisa urea solution.
