Chifukwa 1: Kulephera kwa kutentha kwakukulu
Kutentha kwanthawi yayitali kwa chothandizira cha SCR kumayambitsa kutentha kwambiri, komwe kumachepetsa mphamvu yogwirira ntchito yachitsulo mu chothandizira cha SCR, motero kuchepetsa kwambiri ntchito yothandizira.Ngakhale injiniyo ili bwino ndipo yasinthidwa bwino, mikhalidwe yosiyanasiyana yamisewu imayambitsa kutentha kwambiri kwa SCR chifukwa chogwiritsa ntchito molakwika.
Chifukwa 2: poizoni poizoni
Wamtengo wapatali zitsulo chothandizira pa SCR chothandizira chonyamulira ali adsorption amphamvu pa sulfure, phosphorous, carbon monoxide, chosakwanira combustibles, kutsogolera, manganese, etc. Pa nthawi yomweyo, wolemekezeka zitsulo chothandizira ali amphamvu makutidwe ndi okosijeni catalysis, zomwe zimapangitsa adsorbed chosakwanira combustibles mafuta dizilo. kukhala oxidized, condensed ndi polymerized kupanga colloidal carbon deposit, kuchititsa kutsekeka kwa SCR chothandizira.
Chifukwa 3: Kutsekereza kwa carbon deposit blockage
Kutsekeka kwa SCR catalyst carbon deposit kumapangidwa pang'onopang'ono, komwe kumasinthika.Kutsekekako kumatha kuchepetsedwa ndi njira zamakina monga makutidwe ndi okosijeni ndi mpweya, kapena ndi njira zakuthupi monga kufooketsa ndi kutuluka kwa zinthu zosasunthika ndi zida za mpweya.
Chifukwa 4: Kuchulukana kwa msewu
Chothandizira cha SCR chikhoza kutsekedwa pamene mukuyendetsa misewu yodzaza ndi anthu chifukwa cha kuchuluka kwa zinthu zosakwanira zoyaka moto zomwe zimapangidwa ndi magalimoto panthawi yothamanga komanso kuchepa.
Chifukwa 5: Palibe kugwetsa, kuyeretsa ndi kukonza
Monga kuchuluka kwa carbon colloid kudzatsukidwa panthawi yoyeretsa, n'zosavuta kuchititsa kuti chothandizira cha SCR chitsekedwe, chomwe ndi chifukwa cha kuwonjezeka kwa mafuta a magalimoto ena pambuyo pokonza popanda disassembly.
Chifukwa 6: Kugunda kwakukulu kapena kukokera pansi
Chonyamulira chothandizira chothandizira ndi chipangizo cha ceramic kapena chitsulo.Galimoto yokhala ndi chothandizira cha SCR chotengera ceramic itakokedwa, kugundana kwakukulu kumatha kuthyola maziko a chothandizira ndikuchotsa.
Chifukwa 7: Kulephera kwadongosolo lamafuta
Malo ozungulira mafuta ndi malo omwe ali ndi zolephera zambiri.Ngakhale makina ambiri apamwamba owongolera injini tsopano ali ndi ntchito zodziteteza, silinda ikangolephera, kompyuta imadula yokha jekeseni yamafuta ya silinda ndi kuilepheretsa kupereka mafuta kuti iteteze injini ndi chothandizira, makina ochepa omwe ali ndi izi. ntchito zapamwamba pambuyo pa zonse, ndipo makina ambiri alibe ntchito zoterezi pakalipano.
Chifukwa 8: Pambuyo pa kulephera kwa dongosolo la mankhwala
Pamene urea mpope mu pambuyo mankhwala ali ndi mavuto;Mphuno pa urea dongosolo watsekedwa kapena ali ndi mavuto khalidwe;Urea palokha ndi yosayenerera;Kutaya kwa chitoliro cha gasi mchira;Zidzatsogolera ku zotsatira zoyipa za atomization za jakisoni wa urea.Njira yothetsera urea imapopera mwachindunji pakhoma la chitoliro cha utsi.Pa nthawi yomweyi, chifukwa chitoliro cha mchira nthawi zonse chimakhala kutentha kwambiri, madzi amatha kusungunuka, zomwe zimatsogolera ku crystallization.
