Impompo yamafutha elisezantsi uxinzelelo-ze injini diesel: iimpawu eziphambili kunye nendawo

Injini ye yemoto idla kuthelekiswa entliziyweni yomntu. Kwaye kukho ukufana ethile ngokwenene. Ngenxa intliziyo indoda ehleliyo, kubulelwe motor imoto - ukuhamba. Intliziyo iimpompo igazi emzimbeni - liqinisekisa ukusasazwa yawo onke amalungu ezingundoqo. Xa injini owenza umsebenzi onjalo inkqubo amafutha. Namhlanje sijonga iimpawu kunye nenjongo kwimpompo ephantsi-ingcinezelo. Le sakhi siyinxalenye ebaluleke kakhulu kwinkqubo yamandla. TNND kwakufuneka ukubonelela kukudla impompo yamafutha. Lidla lifakwe ecaleni kwimpompo. Zombini ezi ndlela ezidibene ngokusebenzisa imibhobho apho kwegazi. Ngaxeshanye, amafutha ehamba okucoca apho icocwe.

Ziziphi iingxaki isonjululwe TNND kwinkqubo amafutha

Elisezantsi uxinzelelo-impompo yamafutha ye injini diesel elisombulula ingxaki ebalulekileyo. Amafutha, apho sidla phantsi koxinzelelo ephantsi, kuxhomekeke ekubeni abilayo. Ngenxa ezipokothweni engumphunga kwakheka. Enkungwini amaqamza ukukhanya kuphelela kunye amafutha ziyatyeba bahlukane. Oku kuthetha ukuba pump xi ephantsi iqalisa ukufumana ulwelo kabani viscosity esoloko itshintsha. Ngomhla Inaliti amafutha usebenzisa pump isitofu amafutha kwimo yesiqhelo, kunjalo. Ithotshi esoloko itshintsha yaye akuyi kuwela kungena eziqhelekileyo iparameters.

kanjani TNND

Impompo zidliwe injini diesel nto ndiyibhalayo ephantsi koxinzelelo drive shaft. Ukumpompa lwenziwa nge plane ezikhethekileyo apho kukho ngamaphiko. Kwakhona kokwakhiwa stator inikezelwa, ukusasaza idiskhi kunye gear drive. Xa plane sele actuated, kufikwa kufutshane ngamaphiko stator. Emva koko, ukwakheka iikhamera ngenxa amandla centrifugal. Ekubeni em- pump okudalwe ombane zinikwe amafutha ngqo amafutha ukumpompa kubo. Ukuze wenze oku, kukho imijelo ekwabelaneni disk. Umthamo omncinane diesel ziya kuwa kule ivelufa ukuncitshiswa, ukuba xi ngaphezu kuyimfuneko. Zombini ezi zixhobo oqhagamshelwano phakathi, ngoko yokwenza nokulondoloza imiqathango efunekayo isicelo idreyini ziliminxe okhethekileyo. Le jet, nto leyo kwiglasana ebethelelwa kulo impompo ephakamileyo-ingcinezelo. Ngaloo ndlela, iimeko sidalwe emagumbini kuxhomekeke kwisantya ngayo shaft drive iyajikeleza.

izixhobo pump booster

Impompo booster okanye uxinzelelo eliphantsi amafutha (TNND) ngeeyunithi ngamandla diesel na isakhiwo esilula. It iqulathe namavili nezixhobo zombini, aba ngokusisigxina uthethathethwano kunye nabanye. Ngexesha ujikelezo, amazinyo zezi amagiya ukudala ukuhamba amafutha ngokusebenzisa inkqubo kukudla pump koxinzelelo oluphezulu. Ilungu ephambili nenesakhiwo kwimpompo-pump - piston leyo sifaka amafutha. Ukuze unikezele injini diesel kufuneka iindlela ezimbini nokusebenza piston. Le stroke kunye nenkxaso.

imihlobo TNND

Fuel pump xi phantsi injini diesel - oku enye kuphela uhlobo kwezi ndlela. Ngaphezu koko idizili, ezi zixhobo zingafunyanwa kwezinye iinjini, kungakhathaliseki ukuba imodeli enjini okanye unyaka imveliso. Ngaphandle impompo akwenze - kuyimfuneko ukuba abonelele amafutha ukusuka itanki amafutha kunye nokudlulisela kuyo kwakhona inkqubo. Kwimeko yenjini પ્રતિલિપિ ikopi petroli zisetyenziswa alomelelanga ngamandla iimpompo mechanical. On iiyunithi baxhotyiswe nenkqubo injector amandla kwakunye units diesel amandla usebenzisa pump diesel booster yombane.

TNND mechanical

Le nkqubo ifakwe ngqo kwi block cylinder, wayifaka ngokusebenzisa ngezikhonkwane zesiqhelo. Ukusebenza kwale mpompo inikwa ngokusebenzisa crankshaft ne ome. Ukuba unqakraza kwi cam lukhuni, ngaphakathi ukucuthwa wadala. Ekubeni zamafutha inikezelwa yi kwinkqubo yonikezelo amandla. Ukuze abuye amafutha akuthethi hit, impompo lixhotyiswe isivingco okhethekileyo. Ezinye kew ngokucindezela ukuthumela ipetroli ukuya isiBeki. Ukuba imoto kufakwa TNND uhlobo ngomatshini, ngoko kulula ukuqalisa injini, nkqu-akhawunti elide ime ngxi. Ukuze wenze oku, nje ngesandla ukumpompa afakwe nendlela.

electric

On izithuthi mihla ukusebenzisa amafutha yombane Impompo xi phantsi injini diesel kunye injini inaliti ipetroli. Ukusetyenziswa isixhobo ngomatshini nje akunakwenzeka. Yena ngenxa amandla asezantsi, ayikwazanga ukumelana nale misebenzi. Singadali xi enqwenelekayo ngaphakathi kwinkqubo amafutha. Ngendlela elula zecebo yinto efunekayo pump ngokwayo yaye i-injini yombane livalelwe kuthiwa omnye. Kukho kwakhona kwaye icebo lokucoca nokucoca amafutha, amafutha esingena kunye sensor flow amafutha. Ukuqhuba kunye nokuqhuba imigaqo efana algorithm ukuze ekusebenzeni ngamandla unit. Umahluko kuphela kukuba injini yombane isetyenziselwa ukumpompa kulwelo. Kwinjini olingene TNND ibekwe ngqo ngaphakathi itanki yamafutha. Abanini abaninzi imoto bakholelwa ekubeni ndingatshayi ekhuselekileyo. Enyanisweni, akukho ingozi leyo. Kwimeko amafutha nepetroli ngaphakathi pump lidla ukuba shushu ngokugqithisileyo ngenxa bubushushu, emoyeni i injini. On the analogs zombane ngxaki elinjalo alikho kwaphela. Kwamafutha ihambisa ngaphandle ukuphazanyiswa nemilomo nkqubo kunye nempompo akuthethi cool ingongoma ebalulekileyo. Kwinjini idizili electric TNND amaninzi zidityaniswa impompo koxinzelelo oluphezulu. Oku kunokucaciswa imfuneko anike amafutha ngokuqhubekayo. Oku kuqinisekisa ukusebenza ezinzileyo ye-injini ngezantya ezahlukeneyo.

Uxinzelelo eliphezulu impompo yamafutha (pump fuel)

Esi sixhobo kucingelwa ukuba yenye yezona entsonkothileyo kakhulu injini diesel. umsebenzi wayo ophambili - ukuqinisekisa ukuhamba diesel kwigumbi yokutsha phantsi koxinzelelo oluphezulu. Feed inikwa kuphela phantsi koxinzelelo ethile, kodwa ke ixesha elifunekayo. Mkhonzeni kanye kakhulu inemitha ngekhompyutha yaye ngokupheleleyo ekwafanekisa le umthwalo kwi iyunithi. Kukho iintlobo ezininzi elekhtrons uhlobo izixhobo. Oku ihlanganisa nenkqubo ziphene accumulator kunye namanyathelo ngqo. Izixhobo pump inaliti ye-injini diesel, apho kusetyenziswa umgaqo lisebenza ngqo, Eboniswe ukuba kuyilo sifakwa ibhola, babonelelwa mechanical uhlobo actuator. Ngoko ke, lo inaliti kunye isitofu iyenziwa ngaxeshanye. Xa kwigumbi yokutsha nganye icandelo elahlukileyo kwimpompo atomizes umthamo we yesibaso. Uxinzelelo efunekayo ibonelelwa intshukumo indlela impompo le.

kwimpompo egcwalisekayo kunye neempawu zazo

Le iimpompo baxhotyiswa ibhetri-ngenaliti, ube umahluko. Ngoko ke, yokusebenza impompo actuator iza kusebenza iigesi abe phantsi koxinzelelo kungena cylinder injini. Kwakhona, kungaba kubonelelwa ngokusebenzisa imithombo. izixhobo ngoku eqhelekileyo ezifana accumulator hydraulic. Bona efakwe kwi Iimoto eziphakamileyo-amandla, esebenza kakhulu ngesantya eliphantsi.

Le ezizuzwa basic TNND

Eyona ngxaki - ukuhla yokusebenza isixhobo kunye umaleko idrophu inaliti, ebonelela impompo yamafutha esezantsi-yengcinezelo injini diesel. Kuyenzeka ukuba ukujonga ngokusebenzisa i manometer okanye yepresha, nto leyo ifakiwe emnyango. imveliso amaninzi kubangela elahlekileyo TNND odla kunye jamming yelungu operation. Ngokumalunga isizathu yokuqala, idizili le isenokuba ubumdaka ezahlukeneyo ezithi, nangona acandacanda izinto lokucoca, noxa kunjalo yande vana. Kwakhona kuyenzeka ukuba yehle luthambe le element ukubuya emthonjeni.

Indlela yokulungisa TNND

Ukuba ukusebenza kweyunithi lehla, impompo amafutha injini diesel xi elisezantsi kwaye kufuneka isuswe ukuze babale. Amaxesha amaninzi ukusebenza kwakhona liphuma emva ukugungxula nokucocwa nemingxuma zokusebenza kunye nezinto kwefowuni. Kwakhona, kubalulekile ukuba kuhluzwe kwaye inkunkuma intlaka evela amagumbi yamanzi. Kuba ukulungisa usebenzisa iikiti ukulungiswa kakhulu ukuba ziyafumaneka kwi-mveliso Chinese ukuba wenze izahlulo ze-injini imoto ngoku.

Ukwazi impompo yamafutha esezantsi-yengcinezelo injini diesel, i-siseko esebenza ngayo ifowuni, oko ungalungiseka okanye indawo lula ngayo.
