Kutheni ukhetha iPlastiki eDityanisiweyo eKhawulezayo kwiNkqubo ye-Urea SCR?
Inkqubo ye-Urea Selective Catalytic Reduction (SCR) ibe yinxalenye ebalulekileyo kwiinjini zedizili zanamhlanje ukunciphisa ukukhutshwa okuyingozi.Le nkqubo ixhomekeke kunikezelo oluchanekileyo nolusebenzayo lwesisombululo se-urea kumjelo wokukhupha, apho isabela nge-nitrogen oxides ukuyiguqula ibe yinitrogen engenabungozi namanzi.Ukuqinisekisa ukusebenza kakuhle kwenkqubo ye-Urea SCR, ukusetyenziswa kwezinto ezikumgangatho ophezulu ezifana neziqhagamshelo ezikhawulezayo zeplastiki kubalulekile.Kweli nqaku, siza kuphonononga izizathu zokuba kutheni ukukhetha izihlanganisi zeplastiki ezikhawulezayo zenkqubo ye-Urea SCR sisigqibo esilumkileyo.
ULula ekuTshintsheni nasekulungiseni
Enye yeenzuzo eziphambili zokusebenzisa izixhumi zeplastiki ezikhawulezayo kwinkqubo ye-Urea SCR yinto elula abayinikelayo ngokumalunga nokutshintshwa kunye nokulungiswa.Iziqhagamshelo ezikhawulezayo ze-SAE zeplastiki zenzelwe ukufakwa kunye nokususwa ngokulula, zivumela ukugcinwa okukhawulezayo kunye nokungakhathali.Oku kubaluleke kakhulu kumxholo wenkqubo ye-Urea SCR, apho naliphi na ixesha lokuphumla lingakhokelela ekunyuseni ukukhutshwa kunye nokungahambelani nemimiselo yokusingqongileyo.Ngeziqhagamshelo zeplastiki ezikhawulezayo, amagcisa anokutshintsha ngokukhawuleza okanye alungise izinto, ukunciphisa ixesha lokuphumla kwenkqubo kunye nokuqinisekisa ukusebenza kwayo okuqhubekayo.
Ukuqina kunye nokuthembeka
Izixhumi zeplastiki ezikhawulezayo ezenzelwe inkqubo ye-Urea SCR zenziwe ukuba zimelane neemeko zokusebenza ezinzima ezidibana nazo kwizicelo zeemoto.Zakhiwe ngemathiriyeli ekumgangatho ophezulu enika ukuxhathisa okugqwesileyo kwi-corrosion, vibration, kunye ne-thermal cycling.Oku komelela kuqinisekisa ukuba izihlanganisi zigcina ingqibelelo yazo kubomi benkqubo, zinegalelo ekusebenzeni kwayo okuthembekileyo.Ukongezelela, ukusetyenziswa kwezixhumi ezikhawulezayo zeplastiki kuphelisa umngcipheko we-galvanic corrosion enokuthi yenzeke xa isinyithi esingafaniyo sidibana, siphucula ngakumbi ukuthembeka kwenkqubo.
Ukuhambelana kunye nokusebenza
Izixhumi zeplastiki ezikhawulezayo zenzelwe ukuhlangabezana neemfuno ezingqongqo zenkqubo ye-Urea SCR, ukuqinisekisa ukuhambelana nesisombululo se-urea kunye namanye amacandelo enkqubo.Iziqhagamshelo zenzelwe ukubonelela ngoqhagamshelwano olukhuselekileyo kunye nokuvuza, ukuthintela nayiphi na ilahleko enokubakho yesisombululo se-urea kunye nokugcina ukusebenza kakuhle kwenkqubo.Ngaphaya koko, uyilo oluchanekileyo lweziqhagamshelo zeplastiki ezikhawulezayo zinciphisa imiqobo yokuhamba, ivumela ukuhanjiswa okugudileyo nokungaguqukiyo kwesisombululo se-urea kwi-catalyst, ngaloo ndlela kunyuswa ukusebenza kwenkqubo.
Iindleko-Ukusebenza
Ukongeza kwiinzuzo zabo zobugcisa, izixhumi zeplastiki ezikhawulezayo zibonelela ngesisombululo esineendleko zenkqubo ye-Urea SCR.Ulwakhiwo lwabo olukhaphukhaphu kunye nenkqubo yokufakela lula igalelo ekucutheni iindleko zomsebenzi kunye neendleko zokuhlanganisa.Ngaphezu koko, ukuqina kunye nokuthembeka kweziqhagamshelo ezikhawulezayo zeplastiki kunciphisa imfuno yokutshintshwa rhoqo kunye nokulungiswa, okukhokelela kugcino lweendleko zexesha elide kubenzi bezithuthi kunye nabaqhubi.
Ukuqwalaselwa kokusingqongileyo
Ukusetyenziswa kwezixhumi zeplastiki ezikhawulezayo zihambelana nogxininiso olukhulayo lokuzinza kunye noxanduva lokusingqongileyo kwishishini leemoto.Ezi ziqhagamshelo zisoloko ziveliswa kusetyenziswa izinto ezinokuphinda zisetyenziswe, zibe negalelo ekunciphiseni impembelelo yokusingqongileyo.Ngaphezu koko, ukusebenza ngokufanelekileyo kwenkqubo ye-Urea SCR, eququzelelwa yiziqhagamshelo ezikhawulezayo zeplastiki ezikumgangatho ophezulu, zikhokelela ekukhutshweni okuphantsi kwe-nitrogen oxides, ukukhuthaza umoya ococekileyo kunye nokuthotyelwa kwemimiselo yokukhutshwa.
Ukuqukumbela, ukhetho lweziqhagamshelo zeplastiki ezikhawulezayo zenkqubo ye-Urea SCR ibonelela ngobuninzi beenzuzo, kubandakanya ukusebenziseka ngokulula ekutshintsheni nasekulungiseni, ukuqina, ukuhambelana, ukusebenza kakuhle kweendleko, kunye nokuqwalaselwa kokusingqongileyo.Ngokukhetha iiplastiki eziphezulu zezixhobo ezikhawulezayo ezihambelana nemigangatho ye-SAE, abavelisi kunye nabaqhubi banokuqinisekisa ukusebenza kakuhle kunye nokuthembeka kwenkqubo ye-Urea SCR, ekugqibeleni igalelo kumoya ococekileyo kunye nokuthutha okuzinzileyo.
