Thaum thev naus laus zis tsheb txuas ntxiv mus, qhov kev thov rau cov tshuab tso pa tawm zoo thiab txhim khu kev qha yeej tsis tau ntau dua li no. Ib qho kev daws teeb meem zoo li no, lub V-siv clamp, yog ib qho tseem ceeb hauv cov txheej txheem Selective Catalytic Reduction (SCR) thiab Diesel Particulate Filter (DPF).
Cov noV-Band Clamps muab ib qho kev daws teeb meem tshwj xeeb rau kev ruaj ntseg SCR thiab DPF cov khoom, kom ntseeg tau tias lawv nyob ruaj ntseg hauv qhov chaw nyob rau hauv cov xwm txheej nyuaj ntawm cov tshuab pa tawm niaj hnub. Peb tus qauv V-clamp ua rau kev teeb tsa sai thiab yooj yim, tseem ceeb rau cov chaw tsim khoom uas tab tom nrhiav kev ua kom cov txheej txheem ntau lawm yooj yim dua thaum tswj hwm cov qauv zoo.
Ib qho tseem ceeb ntawm peb cov V-clamps yog lawv qhov sib xws nrog cov khoom tseem ceeb ntawm lub tshuab tso pa tawm. Qhov kev sib xws no yog qhov tseem ceeb, vim nws ua kom cov clamps ruaj ntseg zoo rau SCR thiab DPF cov khoom siv, uas ua lub luag haujlwm tseem ceeb hauv kev txo cov pa phem. Los ntawm kev muab kev sib txuas ruaj ntseg, peb cov V-clamps pab tiv thaiv cov xau uas yuav ua rau muaj kev cuam tshuam rau kev ua haujlwm ntawm lub tshuab tom qab kho. Qhov no tsis yog tsuas yog pab ua raws li cov cai tswjfwm pa phem xwb tab sis kuj pab txhawb rau kev ua haujlwm ntawm lub tsheb tag nrho.
Qhov tseem ceeb ntawm lub tshuab kho tom qab ua haujlwm zoo tsis tuaj yeem hais dhau lawm. Thaum cov tsheb tau nce qib zuj zus, qhov kev thov rau cov thev naus laus zis tswj kev tso pa phem tau nce siab. Piv txwv li, lub tshuab Selective Catalytic Reduction (SCR) siv cov tshuaj urea-based los hloov cov nitrogen oxides (NOx) uas ua rau muaj kev phom sij rau hauv cov nitrogen thiab cov pa dej uas tsis muaj kev phom sij. Lub caij no, lub tshuab Diesel Particulate Filter (DPF) ntes thiab khaws cov pa phem los ntawm cov pa tawm, tiv thaiv nws kom tsis txhob raug tso tawm mus rau hauv huab cua.
Tsis tas li ntawd xwb, peb cov V-clamps ruaj khov thiab txhim khu kev qha, muaj peev xwm tiv taus qhov kub thiab txias siab thiab siab uas feem ntau pom hauv cov tshuab tso pa tawm. Qhov kev tawv no yog qhov tseem ceeb rau kev tswj hwm lub zog ntawm lub tshuab tso pa tawm mus ntev, pab txo qhov yuav ua tsis tiav thiab kho lossis hloov pauv kim heev. Los ntawm kev nqis peev rau hauv cov V-clamps zoo, cov chaw tsim khoom tuaj yeem txuas ntxiv lub neej ntawm lawv cov tshuab kho tom qab, thaum kawg txhim kho kev ua tau zoo thiab txo cov nqi txij nkawm.
Tsis tas li ntawm lawv cov txiaj ntsig ua haujlwm, peb cov V-clamps kuj tseem txhim kho qhov ua haujlwm ntawm lub tshuab tso pa tawm. Cov kab ke SCR thiab DPF uas ruaj ntseg ua haujlwm zoo tshaj plaws, txo cov pa phem thiab ua kom muaj kev ua tau zoo tshaj plaws. Los ntawm kev siv peb cov V-clamps, cov chaw tsim khoom tuaj yeem ua kom tsis yog lawv lub tsheb ua tau raws li cov qauv kev ua raws cai tab sis kuj xa cov kev ua tau zoo tshaj plaws ntawm txoj kev.
Hauv ntej, Lawv tuav cov khoom tseem ceeb xws li SCR thiab DPF kom ruaj ntseg, ua rau lawv yog ib qho tseem ceeb ntawm txhua lub tshuab pa tawm niaj hnub. Los ntawm kev xaiv peb cov V-clamps, cov chaw tsim khoom tuaj yeem txhim kho kev ua haujlwm ntawm lub tsheb, kev ua tau zoo, thiab kev ntseeg siab, xyuas kom ua raws li cov cai tswjfwm kev tso pa tawm thaum muab kev paub tsav tsheb zoo tshaj plaws. Raws li kev lag luam tsheb txuas ntxiv mus, kev nqis peev rau hauv cov khoom zoo xws li V-clamps yuav yog qhov tseem ceeb rau kev nyob ua ntej ntawm qhov nkhaus.
