Umgaqo wokusebenza kwepompo yepetroli yemoto
Ipompo yepetroli ligama elikhethekileyo kushishino lwezixhobo zeemoto. Lelinye lamacandelo asisiseko kwinkqubo yokufaka ipetroli yesithuthi nge-elektroniki, ekwitanki yepetroli yesithuthi. Ipompo yepetroli isebenza xa imoto iqalisiwe kwaye injini isebenza. Ukuba injini iyama ngelixa iswitshi yokutsha ihlala kwindawo ye-ON, imodyuli yolawulo ye-HFM-SFI iya kuyicima umbane oya kwipompo yepetroli ukuthintela ukutsha ngengozi.
Umsebenzi wepompo yamafutha kukutsala ipetroli kwitanki yamafutha, uyicinezele, uze uyithumele kumbhobho wokuhambisa ipetroli. Isebenza kunye nomlawuli woxinzelelo lwamafutha ukuze kumiselwe uxinzelelo oluthile lwamafutha.
Ipompo yamafutha ihambisa ipetroli enoxinzelelo oluphezulu kumbhobho wokusasaza ipetroli ukuqinisekisa ukunikezelwa kwepetroli rhoqo kwii-injectors zamafutha.
Ipompo yepetroli inemoto yombane, isithinteli soxinzelelo, kunye nevalvu yokujonga. Imoto yombane isebenza kwipetroli ngaphakathi kwendlu yepompo. Akukho nkxalabo kuba akukho nto inokutshisa ngaphakathi kwendlu. Ipetroli inokuthambisa kwaye ipholise imoto yepetroli, kwaye ivalvu yokujonga ifakwe kwindawo yokuphuma. Isithinteli soxinzelelo sikwicala loxinzelelo lwendlu yepompo kwaye sinomjelo okhokelela ekungeneni kwamafutha.
Ipompo yepetroli yokunyusa i-ignition yohlobo lwe-ZYB ifanelekile ukuthutha idizili, ioyile enzima, ioyile eseleyo, ioyile yepetroli, njl. Ifanelekile ngokukodwa kwipompo yepetroli kwisitovu sesitishi sokuxuba kwiindlela kunye nobunjineli bebhulorho kwaye yimveliso efanelekileyo yokutshintsha iimveliso ezingenisiweyo. Ipompo yepetroli yokunyusa i-ZYB yohlobo lwe-ZYB ayifanelekanga ukuthutha ulwelo oluguquguqukayo kakhulu okanye oluphantsi, olufana ne-ammonia, i-benzene, njl.
Xa idiski yerotor ijikeleza, iirola zicinezelwa ngaphandle ngamandla e-centrifugal, njengesitywino seoli esijikelezayo. Njengoko irotor ijikeleza, ipompo iyasebenza, itsala ipetroli kwindawo yokungena ipetroli kwaye iyicinezele ukusuka kwindawo yokukhupha iye kwinkqubo yepetroli. Xa ipompo yepetroli icinyiwe, ivalvu yokujonga kwindawo yokukhupha ipetroli iyavalwa ukuthintela ipetroli ukuba ingabuyeli kwi-tank yepetroli. Uxinzelelo olugcinwa yivalvu yokujonga lubizwa ngokuba yi-"residual pressure".
Uxinzelelo oluphezulu lwepompo yepetroli luxhomekeke kumgangatho we-pressure limiter. Ukuba uxinzelelo lwepompo yepetroli ludlula umda woxinzelelo obekiweyo, i-pressure limiter iya kuvula i-bypass ukuvumela ipetroli ukuba ibuyele kwi-inlet yepompo yepetroli.
Ukungasebenzi kakuhle kwepompo yepetroli ezimotweni yingxaki eqhelekileyo kwinkqubo yepetroli, enokuchaphazela ukuqala kwesithuthi, ukukhawulezisa imoto, kwanokhuseleko lokuqhuba. Ngokolwazi olusemthethweni olusemthethweni, oku kulandelayo ziingongoma eziphambili zokuhlela ulwazi:
Iimpawu eziqhelekileyo zokungasebenzi kakuhle kwepompo yepetroli
Ubunzima bokuqalisa imoto: Kuthatha imizamo emininzi ukuqala imoto emva kokuba iqalile okanye ipakishwe kubanda, ngenxa yokungakwazi kwepompo yepetroli ukumisela uxinzelelo olwaneleyo lwepetroli.
Ukukhawulezisa okanye ukuxhuzula okubuthathaka: Kukho impendulo ebambezelekileyo okanye "ukuxhuzula" xa ukhawulezisa ngokukhawuleza.
Ingxolo engaqhelekanga ngexesha lokuqhuba: Isandi sokubhuza esiqhubekayo siphuma kwindawo yetanki yepetroli (ngesiqhelo phantsi kwesihlalo esingasemva), mhlawumbi ngenxa yokuguguleka kwangaphakathi okanye ukuvaleka.
Isibane se-injini siyavula: Ukunikezelwa kwamafutha ngendlela engaqhelekanga kubangela uxinano olungaqhelekanga lomxube, nto leyo ebangela i-alamu ye-ECU.
Ukushukuma kwenjini: Ukunikezelwa kwamafutha okungazinzanga kubangela ukutsha okwaneleyo.
Ukungakwazi ngokupheleleyo ukuqalisa: Impompo yepetroli iyaphela ngokupheleleyo, kwaye inkqubo yokubonelela ngepetroli iyawa.
Qaphela: Ezinye iimodeli zeVolkswagen ezinesandi esivakalayo ngasemva ngasekunene emva kokucima kwenjini zezokuzihlola ngokwazo ipompo yokufumanisa ukuvuza kwetanki yepetroli, into eqhelekileyo kwaye ayikokusilela kwepompo yepetroli.
Izizathu eziqhelekileyo zokungaphumeleli
Umgangatho wepetroli ophantsi: Ipetroli ephantsi iqulethe ukungcola okungena kwi-motor pump pump okanye kwi-filter, nto leyo ekhawulezisa ukuguguleka.
Ukuqhuba ipetroli ephantsi ixesha elide: Ioli yetanki yepetroli iphantsi kakhulu (njengokufaka ipetroli kuphela xa isibane sesalathisi sepetroli sivuliwe), okubangela ukungasebenzi kakuhle kobushushu kunye nokushisa kakhulu kunye nokucinywa kwepompo yepetroli.
Isihluzi sepetroli esingatshintshwa rhoqo: Emva kokuvaleka, ipompo yepetroli isebenza phantsi komthwalo omkhulu, inokuba nomonakalo okhawulezileyo.
Ukonakala kwangaphakathi koomatshini: Okufana ne-rotor, i-impeller, iibhrashi zekhabhoni, njl.njl., kuyaguga ngokuhamba kwexesha.
Ukusilela kwesekethe okanye imodyuli yokulawula: Ukungasebenzi kakuhle kombane, umonakalo wereyila, njl.
Isiphene soyilo (iimpawu ezithile): Umzekelo, ezinye iimodeli ze-SAIC-GM (2019–2023 Buick Envision, Envision, njl.njl.) zineengxaki ezinzulu ngenxa yokusebenza kakubi kokuxhathisa ukufuma kwemodyuli yolawulo lwepompo yamafutha.
Iingcebiso zokuphatha
Yima ngoko nangoko uze ujonge: Ukuba kukho ukukhawulezisa okubuthathaka kakhulu, ukucima kwenjini, okanye ukungakwazi ukuqala, yima imoto ngoko nangoko ukuze uphephe ingozi. Uhlolo loBungcali: Yiya kwivenkile ye-4S okanye kwivenkile yokulungisa ethembekileyo kwaye usebenzise uvavanyo loxinzelelo lwepetroli ukuze ubone ukusebenza kwepompo yeoyile.
Jonga ulwazi lokurhoxiswa kwesithuthi: Ukuba sisithuthi sophawu lweBuick, Chevrolet, okanye iCadillac, ungajonga ukuba sikwindawo yokukhutshwa kwesithuthi:
上汽通用召回查询入口 (ULawulo lweMarike yeSizwe kunye neZiko loLawulo-iZiko loLawulo lweMveliso enesiphene)
Ngoku ka
Ukususela nge-31 kaMeyi 2024, ezinye iimodeli zeBuick, Chevrolet, kunye neCadillac zowama-2019-2023 zibonelelwe ngokutshintshwa simahla kwemodyuli yokulawula ipompo yamafutha ephuculweyo.
Ukuthintela Imihla ngemihla:
Sebenzisa ipetroli esemgangathweni ophezulu evela kwisikhululo sepetroli esiqhelekileyo；
Kuphephe ukugcwalisa ipetroli xa itanki yepetroli iphantse ingabi nanto;
Tshintsha isihluzi sepetroli rhoqo ngokwemiyalelo yokulungisa.
Ukuba ukrokrela ukuba ipompo yeoyile ayisebenzi kakuhle, musa ukuyiqhekeza okanye ukuyibetha itanki yepetroli (kuphela ngenxa yoncedo olungxamisekileyo lwexeshana lokunamathela kwebrashi yekhabhoni, enomngcipheko omkhulu) ；
Nxibelelana ne-arhente yokulungisa enobuchule ngokukhawuleza ukuze uyilungise.
