Imodoka yimbeho urea amazi azahagarara? Tuvuge iki ku gukonja? Urashaka kongeramo antifreeze ubushyuhe buke urea?
Ubushyuhe bukimara kugabanuka mu gihe cy'itumba, abafite imodoka benshi, cyane cyane mu majyaruguru, byanze bikunze bahangayikishijwe no gukonjesha ikigega cya urea, bazabaza niba imodoka urea izahagarara, uburyo bwo kuyihagarika, niba wongeyeho nyirinzu ubushyuhe buke urea nibindi bibazo, hamwe nabafite imodoka bamwe basimbuza byimazeyo igisubizo gisanzwe cya urea nigisubizo cya urea ya -35 ° C, bakibwira ko ibi byoroshye, mubyukuri, ntabwo aribyo. Ntabwo bisaba amafaranga gusa ahubwo byangiza byoroshye sisitemu yimodoka. Noneho reka dukwirakwize ubwenge bwibanze.
Kuki wongeyeho igisubizo cya urea?
Ni izihe ngaruka zo kutongera?
Icyitwa ibinyabiziga bya urea, bizwi kandi nka mazutu yo gutunganya mazutu ya mazutu, bivuga igisubizo cya urea gifite ingufu za urea zingana na 32.5% hamwe n’umuti w’amazi meza cyane, kandi ibikoresho byayo ni kristu ya urea n’amazi meza cyane. Yashyizwe mu kigega cya urea, mugihe umuyoboro usohoka ugaragara ko ufite azote ya azote, ikigega cya urea gihita gisohora igisubizo cy’imodoka urea, kandi ibisubizo bibiri bya REDOX bibera mu kigega cya reaction ya SCR, bikabyara azote idafite umwanda n’amazi, kugabanya ibyuka bihumanya ikirere.
Ihame ry'imikorere ya sisitemu ya SCR: Hamwe no gukundwa kwamamodoka ane yigihugu, atanu yigihugu, ndetse nyuma yaho imodoka esheshatu zigihugu, urea yimodoka ishobora kuvugwa ko ari inyongera ya SCR, kandi nigicuruzwa cyingenzi kubinyabiziga bya mazutu nka kamyo na bisi kuzuza ibipimo bitanu byigihugu na bitandatu.
Kutongeramo igisubizo cya urea igihe kinini, cyangwa gukoresha amazi meza cyangwa amazi ya robine aho, bizangiza cyane urea nozzle ndetse na sisitemu yose nyuma yo kuvurwa. Kumenya ko gusimbuza urea nozzle akenshi ari ibihumbi byamafaranga, sisitemu yose ikenera 30.000 kugeza 50.000.
Niki -35 ℃ ikinyabiziga urea igisubizo?
Urashaka kongeramo ubushyuhe buke urea igisubizo?
Umuti urea wibinyabiziga uteganijwe n’ibihugu bine by’igihugu ibipimo bitanu byoherezwa mu kirere bitangira gukonja ku bushyuhe busanzwe buri munsi ya -11 ° C. Ababikora ku giti cyabo bakoresha inyongeramusaruro (Ethanol cyangwa Ethylene glycol) kugira ngo bagabanye ubukonje bwa urea y’imodoka, kugira ngo babigereho intego yo kurwanya ubukonje. Nyamara, Ethanol mu nyongeramusaruro irashya kandi iraturika, kandi umuyoboro usohora ibinyabiziga uri ku bushyuhe bwinshi, niba ingufu za Ethanol ari nyinshi cyane, bizangiza ibyangiritse. Mu bihe bimwe na bimwe by'ubushyuhe, Ethylene glycol izabyara aside, izatera ruswa ku muyoboro usohoka kandi itera kumeneka. Kubwibyo, nta mpamvu yo gukoresha icyo bita -35 ° C yimodoka ya urea yumuti, kandi cyane cyane, igisubizo cya -35 ° C cyumuti urea uhenze hafi 40% ugereranije nibisanzwe kumasoko.
Ese igisubizo cya urea gikonja mugihe cy'itumba?
Nakora iki iyo nkonje?
Ese igisubizo cya urea gikonja mugihe cy'itumba? Nakora iki iyo nkonje? Mubyukuri, ibyo bibazo, ababikora babitekereje kuva kera, mubisanzwe bakeneye kurwanya antifreeze ya ruguru yimodoka ya SCR ifite ibikoresho byo gushyushya tanke ya urea, mugihe ubushyuhe bwamazi ya moteri bugeze kuri dogere 60, ubushyuhe bwamazi ya urea buri munsi ya dogere -5 Celsius, kuva pompe ya moteri kugeza kuri moteri ya urea tank ya moteri izakingura urujya n'uruza, kugirango habeho korohereza amazi ya urea muri tank ya urea.
Kubera ko SCR ikeneye ubushyuhe bwa moteri kugirango igere kuri 200 ° C kugirango yinjire mu kazi, amazi ya urea ntazaterwa ku bushyuhe buke, kugirango atange umwanya uhagije wamazi ya urea yashonze.
Kubwibyo, nta mpamvu yo guhangayikishwa n’uko igisubizo cya urea kizahagarara, nuburyo bwo gukora nyuma yo gukonja. Byongeye kandi, no mu turere dukonje cyane, nta mpamvu yo kongeramo icyitwa ubushyuhe buke bwa urea.
