Umgangatho olungileyo weDizili wePump Plunger 3 418 403 005 3403-005 iDiesel Pump Parts 3418403005 3403005 yePump yeInjini

Umsebenzi wepompo ye-injection ye-fuel kukuhambisa i-fuel pressure ephezulu kwi-injector ye-fuel injector ngexesha elifanelekileyo kunye nobungakanani ngokwemiqathango yokusebenza ye-injini ye-diesel kunye nomyalelo wokusebenza we-cylinder.

I-1.I-Multi-cylinder yemoto ye-diesel fuel injection pump kufuneka ihlangabezane nezi mfuno zilandelayo

(1))Ubungakanani be-oyile enikezelwe kwi-cylinder nganye iyalingana. Ngaphantsi kwemeko yokulinganisa, umehluko kwi-oyile ye-cylinder nganye ayikho ngaphezu kwe-3% ~ 4%. Unikezelo lwamafutha lwempompo yokutofa kwamafutha kufuneka lutshintshwe ngotshintsho lwemeko yokusebenza ye-injini ye-diesel, ngoko ke impompo yesitofu se-fuel kufuneka ibe nesixhobo sokulungelelanisa unikezelo lwamafutha.
(2) Unikezelo lwe-oyile kwangaphambili I-engile yesilinda nganye iyafana, kwaye impazamo ingaphantsi kwe-0.5 ° ~ 1 ° i-engile ye-crankshaft. I-Angle yonikezelo lwamafutha kwangaphambili kufuneka itshintshe kwimeko yokusebenza kwe-injini ye-diesel, ngoko ke isixhobo sangaphambili sokutofa kwamafutha kufuneka sifakelwe.
(3) I-oyile yokubonelela nge-Angle yesilinda nganye iyahambelana.
(4) Unokumisa ngokukhawuleza unikezelo lwe-oyile ukuthintela isitofu se-oyile ekuvuzeni.

Kukho iintlobo ezininzi zeempompo zokutofa kwepetroli, ezisetyenziswa kakhulu kwiinjini zedizili zemoto, njengempompo yokutofa i-plunger ye-in-line kunye ne-rotor yokuhambisa isitofu se-fuel pump. Ukongeza, kukho iimpompo - imibhobho kunye nokunye.

2. Uthotho lwempompo yokutofa yohlobo lwePlunger

Ngenxa yokuba amandla e-cylinder enye ye-injini ye-diesel ahluka ngokubanzi, ukuba impompo yokutofa kwe-fuel iyilwe kwaye yenziwe ngokomjikelezo we-oyile yobonelelo olufunwa ngumbane we-cylinder nganye, imilinganiselo yobungakanani bempompo yokutofa i-fuel iya kuba yinto eninzi, ibangela ezininzi. ukuphazamiseka kwimveliso kunye nokusetyenziswa. Ke ngoko, abavelisi bempompo yokutofa emhlabeni basekwe kwimivumbo emininzi eyahlukeneyo ye-plunger, impompo yokutofa yahlulwe yaba luthotho okanye iimodeli ezimbalwa, kwaye ke kunye nobukhulu obahlukeneyo beendawo zokudityaniswa kwe-plunger, ukwenza inani leempompo zesitofu ngamafutha ahlukeneyo. izixa zokubonelela ukuhlangabezana neemfuno zeenjini ezahlukeneyo zedizili zamandla. Itheyibhile 5-4 idwelisa uluhlu oluninzi lweempompo zesitofu se-plunger eziveliswe eTshayina kunye neeparitha zazo eziphambili.

A, B uthotho lwempompo yokutofa kwamafutha okanye A, uhlobo lwe-B lwempompo yesitofu sesiseko sesiseko siyafana, sisakhiwo semveli sempompo yokutofa kwe-plunger ye-in-line. I-P-type fuel injection pump inendlela entsha, kwaye ithatha ibhokisi-uhlobo lokutywina umzimba wempompo ngaphandle kokuvula ifestile yecala ukuqinisa isakhiwo sempompo yokutofa kwamafutha. Oku kulandelayo kuchaza ubume kunye nomgaqo wokusebenza wohlobo A kunye nohlobo lwempompo yesitofu se-P.

3.Umgaqo wokuSebenza wohlobo lwempompo yokutofa kwamafutha

Xa i-camshaft yepompo ye-injection ye-fuel ijikeleza, ukuba i-tappet roller iqengqeleka kwisiseko sesiseko se-CAM, i-plunger imisa kwindawo esezantsi efileyo kwiziko le-plunger. Ukuba i-roller roller kwicandelo lokuphakamisa i-CAM, i-CAM igxotha i-tappet, kwaye i-tappet iqhubela i-plunger phezulu, ngelixa i-splunger spring ixinzelelwe. Xa i-roller iqengqeleka ngaphaya kwe-arc ephezulu ye-CAM, i-plunger ifikelela kwindawo ephezulu efileyo ye-plunger. Emva koko i-roller rolls kwicandelo lokulahla i-CAM, i-plunger spring ityhala i-plunger, kwaye i-plunger ityhala i-tappet phantsi de i-roller roller kwisiseko somgangatho we-CAM, kwaye i-plunger ibuyela kwi-stop stop ye-plunger. Oko kukuthi, xa impompo yesitofu se-fuel isebenza, ngokujikeleza kwecamshaft, i-tappet kunye ne-plunger zibuyisela kwi-tappet emngxunyeni kunye nomkhono we-plunger ngokulandelelana phakathi kwendawo ephezulu kunye nesezantsi efileyo yeplunger.
