Le Cov pa roj recirculation valve gasket muaj los kaw lub valve qhov twg nws txuas mus rau lub tso pa tawm. Qhov no lav nws qhov nruj thiab tiv thaiv cov pa tawm. Yog li, lub luag haujlwm ntawm EGR valve foob yog txhawm rau tiv thaiv kev xau.
Rau qhov no, nws yog pob khawm muaj peev xwm tiv taus qhov kub thiab txias uas tuaj yeem ncav cuag ntau pua degrees.
🔍 Cov tsos mob ntawm HS EGR valve foob yog dab tsi?
Kev ua tsis tiav ntawm EGR valve foob yuav ua rau lub valve tsis ua haujlwm thiab xau. Tom qab ntawd koj yuav ntsib cov tsos mob hauv qab no:
- Poob lub zog tsheb ;
- Cov pa luam yeeb dub los ntawm cov pa tawm ;
- Lub teeb lub cav yog qhib ;
- Jerks ntawm lub tsheb.
Koj tseem yuav ua phem rau ib puag ncig ntau dua, uas tuaj yeem ua rau kev tso tseg ntawm kev tswj hwm. Sealing HS EGR valve tuaj yeem ua rau muaj roj ntau dhau.
Hmoov tsis zoo, tag nrho cov tsos mob no tuaj yeem tshwm sim yog tias cov pa roj recirculation valve nws tus kheej tsis ua haujlwm. Yog li ntawd, nws raug nquahu kom koj xyuas nws kom pom tias qhov teeb meem nrog lub valve, nws lub valve, lossis lub foob.
Yog tias muaj teeb meem nrog lub foob, nws tuaj yeem hloov tau. Yog hais tias, ntawm qhov tod tes, qhov teeb meem yog nrog cov pa roj recirculation valve, nws yuav tsum tau ntxuav los yog hloov.
🛠️ Yuav ua li cas hloov cov pa roj recirculation valve roj foob?
Kev hloov ntawm EGR valve foob yuav tsum tau ua nrog lub foob sib npaug uas muaj peev xwm tiv taus cua sov. Yog li ntawd, koj yuav tsum tsis txhob siv cardboard, ntawv lossis cork spacers, vim qhov no yuav tshwm sim rau lwm qhov ntawm koj lub tsheb.
