Kudziwa za njira yapadera ya urea

Galimoto urea ndipo nthawi zambiri amatero urea wauminiral urea wasiyana. Galimoto urea ndikuchepetsa nayitrogeni ndi mawonekedwe a hydrogen omwe amatulutsidwa ndi injini ya disilo, ndikuchita nawo kuteteza chilengedwe. Imakhala ndi zofunikira zongoyerekeza, zomwe zimapangidwa ndi madzi okwanira a urea ndi owoneka bwino. Chimodzi mwazofunikira kwambiri ndi kuchuluka kwa zosayenera. Tinthu tating'onoting'ono, zitsulo zitsulo, michere ndi zodetsa zina ku Urea ndizovuta kwambiri, ndipo zovuta ndizodziwikiratu. Ikakhala kuti urea wosakhazikika utawonjezeredwa, zimayambitsa kulephera pambuyo pa pambuyo pokonza, ndipo ngakhale kupanga zoopsa zosasinthika kukweretsedwa. Ndipo kwa masauzande a Yuan atatha kukonza, kapena kusankha urea wovomerezeka ndi wopanga.

Kodi ndi mikhalidwe yotani?

Weichai wapadera wa Urea Sourt akumana ndi ISO2222411-1, Germany Standard Gu70070 ndi Interner Standard GB29518, a Mboni.

Kuvulaza kwa zinthu zabodza komanso zopanda pake: Kuthetsa kwamphamvu kwa urea sikufika pamlingo, zoyera sikokwanira ku Urea, kusanja mphuno za urea, kutsekereza ndikuphika. Komabe, kugwiritsa ntchito kwakanthawi kwagalimoto komwe sikukwaniritsa miyezo yoyeserera yomwe ili ndi boma kumachepetsa kuthamanga kwa Noxi, kuchepetsa mphamvu ndi moyo wa SCR System.

Oyera oyera

Kuti mukwaniritse zofunikira zapamwamba za URRA-Hight, Wetichai zapadera za Urea ziyenera kudutsa mitundu yosiyanasiyana yopanga ndi njira zosiyanasiyana pakupanga, ndipo zida zapamalo ziyenera kukhala zopanda fumbi. Mfundo yofunika kwambiri ya SPR System: Kutulutsa kumalowa mu chitoliro chopopera kuchokera ku turger. Nthawi yomweyo, ndi ulea jakisoni wa urea ukhazikitsidwa mu DPF, madontho a urea amapezeka ndi ma pyrolysis pansi pamagetsi, ndikupangitsa NH3, NH3 amachepetsa Nox pansi pa chothandizira. Mu dongosolo la Scr Rection, ndende ya Urea yankho ndi imodzi mwazinthu zazikulu, koma zokwera kwambiri kapena zotsika kwambiri sizingathandize kutembenuka kwa Nox ndi mapangidwe achiwiri odetsa Amoni.

Kusintha pang'ono

Ndi njira yapadera ya urea ndi ndende ya 32.5% monga kuchepetsa nthumwi; Monga momwe kusinthira kwa post-chithandizo cha Scr, kugwiritsira ntchito ndalama za Urea kwa pafupifupi 5% ya kumwa mafuta. Tengani mphamvu ya 23lde urea tank monga chitsanzo, mileage imatha kufikira makilomita 1500-1800.

Urea onjezerani madzi: Nthawi zambiri munthu amafunsa ngati urea amatha kuwonjezera madzi amchere, madzi owiritsa ndi zinthu zina. Izi sizotheka, pali zodetsa zambiri m'madzi apampopi, kuposa zomwe tikuwona. Calcium, magnesium, sodium ndi zinthu zina mu bomba lamadzi ndi madzi ndiosavuta kupanga zinthu zolimba, zomwe zimalepheretsa zolakwitsa za ku URA. Madziwo adawonjeza mu urea, ungakhale madzi owoneka bwino. Mlingo wa urea wowoneka bwino umasungidwa pakati pa 30% ndi 80% ya kuchuluka kwa thanki ya urea. Kusungirako Urea: Urea yankho kuyenera kusungidwa mu chitseko chotsekedwa mu malo ozizira, owuma, kutali ndi oxidants amphamvu. Mukadzaza, monga mu tank ya urea kutaya urea wowaza, ndikupanga kuwonongeka kwa chilengedwe. Zida zaukadaulo zimalimbikitsidwa.

Chidziwitso chodzaza Urea: Njira yothetsera ya urea ndi yochepetsera khungu. Ngati khungu kapena maso awonjezeredwa, muzimutsuka ndi madzi posachedwa; Ngati ululu ukupitiliza, chonde pitani kuchipatala. Ngati kumeza mosasamala, koletsa kusanza, pezani chithandizo chamankhwala mwachangu
