UmGangatho oPhezulu wokuTofa iPumpu yeDizili BHT6P120R izahlulo zeNjini yeFuel ye-Weichai Deutz Wd615 Lgmg

Indima:Impompo yokutofa kwamafutha yeyona nto ibalulekileyo kwinkqubo yonikezelo lwedizili kwaye ibizwa ngokuba "yintliziyo" yenjini yedizili.

Umsebenzi:Ngokomthwalo we-injini ye-diesel, hambisa idizili yoxinzelelo oluphezulu kwi-injector rhoqo kunye nobungakanani. Olona hlobo luxhaphakileyo lusetyenziswa yinjini yedizili yile: impompo yesitofu se-plunger.

Amacandelo:I-plunger fuel injection pump inezi zixhobo zilandelayo: itanki ye-fuel, i-fuel transfer pump, i-low-pressure fuel pipe, i-fuel filter, i-fuel injection pump, i-high-pressure fuel pipe, i-injector fuel kunye ne-return pipe, njl.

Inkqubo yokusebenza:Isibaso esikwitanki yamafutha sithunyelwa kwimpompo yokutofa kwamafutha ngesihluzo samafutha kuxinzelelo oluthile (0.15~0.4MPa) ngempompo yokuhambisa amafutha. Imveliso yepetroli yoxinzelelo oluphezulu olusuka kwimpompo ye-injection ye-fuel ingena kwi-injector ye-fuel ngokusebenzisa umbhobho we-oyile ophezulu kwaye ifakwe kwigumbi lokutshisa. Ekubeni umthamo wonikezelo lwepetroli wempompo yokuhanjiswa kwamafutha ngama-3-8 amaxesha amakhulu kunempompo yokutofa kwe-fuel, i-fuel engaphezulu ibuyela kwi-tank ye-fuel ngokusebenzisa i-valve yokunceda efakwe kwi-filter (ekwalawula uxinzelelo lokuhambisa amafutha). Ukuba ivalve yoncedo icwangciswe ngaphandle kwegumbi lokungena kwi-oyile yempompo yokutofa kwe-fuel, yonke i-fuel iya kuhamba ngegumbi lokungena kwe-oyile yempompo yokutofa kwamafutha, kwaye umphumo wokupholisa ungcono. Nangona kunjalo, kwangaxeshanye, isihluzi kufuneka sigqithise onke amafutha, ngoko ngamanye amaxesha ubukhulu kufuneka bunyuswe. Amafutha avuzayo kwi-injector abuyela kwitanki yamafutha ngombhobho wokubuyisela amafutha (inokudityaniswa nombhobho oyintloko wokubuyiswa kwamafutha). Akunakuze kuvunyelwe ukudibanisa umbhobho wokubuyisela we-injector kumbhobho ngoxinzelelo oluthile, olufana nombhobho ovela kwipompo yeoli ukuya kwisihlunu. Kungcono ukudibanisa imibhobho ye-oyile yazo zonke ii-injector kumbhobho owahlukileyo ongaxinzelelwanga wokubuyiswa kwe-oyile ukuze ubuyele etankini. Ezinye iinjini zedizili zinesixhobo esenza ukuba yonke inkqubo yeoli ikwazi ukususa umoya ngokuzenzekelayo. Oko kukuthi, kufuneka kubekho umahluko wobude kumbhobho ukusuka kwisihluzi ukuya kwimpompo yokutofa kwamafutha ukuze kuqinisekiswe ukuba umoya kunye namaqamza omphunga wamafutha kumbhobho anganyuka aye phezulu kwesihluzo. Ukusuka apho ihamba ngombhobho ophuphumayo ukuya kwitanki yamafutha.
