IValve yokuhanjiswa kwexabiso leFactory eyi-504660 ye-Simms Minimec Impompo

Impompo yesitofu 'yintliziyo' ye-injini xa kukho ukusilela kuya kwenza ukungasebenzi kakuhle kwe-injini Impompo yonikezelo lwamafutha oxinzelelo oluphezulu yinxalenye yoxinzelelo oluphezulu lwenkqubo yesitofu kaloliwe exhaphakileyo yenaliti yoxinzelelo oluphezulu ukubonelela ngokuzinzileyo nokuqhubekayo. I-high-pressure fuel injector pump plunger intshukumo kwinkqubo ye-high-frequency movement yevalve yokuphuma ichaphazela ukuthembeka kunye nokuzinza kwevalve xa i-fuel-high-pressure fuel. ukuvuza kumphezulu wokutywina ꎬ ukungabikho koxinzelelo lwamafutha ꎬ inkqubo kaloliwe eqhelekileyo. Xa isibaso soxinzelelo oluphezulu sivuza kumphezulu wokutywina, uxinzelelo lwamafutha kwinkqubo kaloliwe eqhelekileyo ayonelanga, nto leyo ekhokelela kuxinzelelo lwenaliti olungonelanga lwesitofu kunye ne-atomisation embi, ekhokelela ngokumandla kumandla e-injini aphantsi okanye nokusilela ukuqalisa. Kweli phepha, ukuze kulungiswe ingxaki yokungaphumeleli kokutywinwa koxinzelelo oluphezulu olubangelwa yi-cavitation kwi-valve yokuphuma, sihlalutya isakhiwo sevalve yokuphuma kunye nokwandisa isakhiwo sevalve ngokusebenzisa izibalo ze-finite-element simulation kunye neemvavanyo zokuqinisekisa. ukuba uyilo olulungisiweyo lusebenza kakuhle ekusombululeni ingxaki ye-cavitation.

Ivalve yokuphuma ifumaneka kwindawo ephezulu yeplunger yempompo yokutofa kwaye iqhagamshelwe kwigumbi le-accumulator yoxinzelelo oluphezulu. Ivalve yokuphuma iyindlela enye kwaye i-fuel inokudlula kuphela kwicala elinye kwaye kwelinye icala, elinokuthi livale i-fuel-high-pressure. Isakhiwo kunye nenkqubo yokusebenza ye-valve yokuphuma yile ndlela ilandelayo: xa ikhamera ijikeleza kwi-flat part yeprofayili yekhamera, i-plunger ihamba phantsi kwaye uxinzelelo olubi luveliswa kwigumbi le-plunger. Xa umehluko woxinzelelo phakathi kwendawo yokungena kunye negumbi le-plunger lifikelela kuxinzelelo lokuvula lwevalve, ngoko, xa i-spool ye-inlet ihamba ihla, i-valve iya kuvulwa kwaye i-fuel iya kufakwa kwimpompo yokubonelela nge-inlet spool. Xa ikhamera ijikeleza ukuya kumgca ophakanyisiweyo weplunger intshukumo enyukayo yomthamo wegumbi lokusebenza iba yincinci yoxinzelelo lwegumbi inyuka ngokukhawuleza xa igumbi eliphezulu loxinzelelo oluphezulu livula ivalve yokukhupha i-spool yoxinzelelo oluphezulu lokuhamba kwamafutha ukuya kumbhobho kaloliwe oqhelekileyo xa iplunger isuka ezantsi ukuya ezantsi ukuya. inkqubo yokumpompa ephezulu yokumpompa iphelile i-injector pump plunger reciprocating process yokukhupha ivalve spool ukutshintsha rhoqo utshintsho loxinzelelo lwamafutha kwindawo enkulu yokutywina yoxinzelelo oluphezulu. Ithambekele kwi-cavitation ikhokelela kwindawo yokukhupha ivalve yokutywina umphezulu wezixhobo zokutywina umphezulu wokutywina. Ivalve yeoyile yokutywina umphezulu imathiriyeli yokutywina ukutywina ukusilela ukutywina ukutyibilika kwenjini yedizili esekwe emhlabeni yenzekile kwinani le-injection yepompo yokukhupha ivalve cavitation ukusilela ukunyamezela uvavanyo lweeyure ezingama-500 zoxinzelelo oluphezulu lokutywinwa komphezulu wesixhobo sevalve yokukhupha ukugqabhuka, ukutywinwa. ingxaki yokungaphumeleli ingaphantsi kakhulu kwiimfuno zobomi bejenereyitha ezisetyenziswa ngokuqhelekileyo
