Yakanaka Yakanaka Diesel Pump Plunger 3 418 403 005 3403-005 Diesel Pump Zvikamu 3418403005 3403005 yeInjini Pump

Basa repombi jekiseni remafuta ndere kuendesa yakakwira yekumanikidza mafuta kune injector yemafuta panguva uye yakawandisa maererano nemamiriro ekushanda einjini yedhiziri uye kurongeka kwecylinder.

1.Multi-cylinder motokari diesel mafuta jekiseni pombi inofanira kusangana zvinotevera zvinodiwa

(1)) Huwandu hwemafuta anopihwa kune imwe neimwe silinda akaenzana. Pasi pemamiriro ekugadzirisa, mutsauko mukupihwa kweoiri yecylinder yega yega haupfuuri 3% ~ 4%. Kupihwa kwemafuta epombi yejekiseni yemafuta kunofanirwa kushandurwa nekushandurwa kweinjini yedhiziri yekushanda mamiriro, saka pombi yejekiseni yemafuta inofanirwa kunge iine mafuta ekugadzirisa gadziriso.
(2) Iyo oiri yekupa yepamberi Angle yecylinder imwe neimwe yakafanana, uye kukanganisa kuri pasi pe0.5 ° ~ 1 ° crankshaft Angle. Iyo mafuta ekufambisa mberi Angle inofanirwawo kuchinja neinjini yedhiziri yekushanda, saka iyo jekiseni remafuta epamberi mudziyo unofanirwa kuiswa.
(3) Mafuta ekupa Angle yecylinder yega yega inowirirana.
(4) Inogona kukurumidza kumisa kupihwa kweoiri kudzivirira jekiseni remafuta kubva pakudonha.

Kune akawanda marudzi emajekiseni epombi, ayo anoshandiswa zvakanyanya mumotokari injini dzedhiziri, senge in-line plunger mafuta jekiseni pombi uye rotor kugovera mafuta jekiseni pombi. Uyezve, pane pombi - nozzles uye zvichingodaro.

2. Plunger mhando mafuta jekiseni pombi series

Nekuti silinda imwe chete simba reinjini yedhiziri inosiyana zvakanyanya, kana pombi jekiseni remafuta rakagadzirwa uye kugadzirwa zvinoenderana neairi kutenderera mafuta anodiwa nesimba rega rega resilinda, saizi yekumisikidzwa kwepombi jekiseni yemafuta ichave isingaverengeki, zvichikonzera zvakawanda. kusagadzikana pakugadzirwa uye kushandiswa. Naizvozvo, vagadziri vepombi yejekiseni munyika vakavakirwa pane akati wandei akasiyana plunger sitiroko, iyo jekiseni pombi inokamurwa kuita mashoma akatevedzana kana mamodheru, uyezve neakasiyana saizi ezvimedu zvekubatanidza plunger, kugadzira akati wandei epombi jekiseni nemafuta akasiyana. kupa huwandu hwekuzadzisa zvinodiwa zveakasiyana emagetsi edhiziri injini. Tafura 5-4 inonyora akati wandei akateedzana e-in-line plunger mafuta ejekiseni pombi anogadzirwa muChina uye iwo makuru ma paramita.

A, B akatevedzana mafuta jekiseni pombi kana A, B mhando mafuta jekiseni pombi musimboti chimiro chakafanana, ndiyo yechinyakare chimiro che-mutsara plunger jekiseni pombi. Iyo P-mhando yemafuta jekiseni pombi ine nzira itsva, uye inotora bhokisi-mhando yekuisa chisimbiso pombi muviri pasina kuvhura hwindo rekudivi kusimbisa chimiro chepombi jekiseni remafuta. Inotevera inotsanangura chimiro uye nheyo yekushanda yemhando A uye mhando P mafuta jekiseni pombi.

3.Kushanda nheyo yeA type fuel injection pump

Kana iyo camshaft yepombi yejekiseni yemafuta ichitenderera, kana tappet roller ikakunguruka pachigadziko cheCAM, plunger inomira panzvimbo yepasi yakafa centre yeplunger. Kana iyo roller ikakunguruka kuenda kuCAM kusimudza chikamu, CAM inosundidzira tappet, uye tappet inosundira plunger kumusoro, nepo plunger chitubu ichimanikidzwa. Kana iyo roller ichitenderedza pamusoro peiyo arc yeCAM, iyo plunger inosvika panzvimbo yepamusoro yakafa yeplunger. Ipapo roller inokunguruka muchikamu chekudonhedza cheCAM, chitubu cheplunger chinosundidzira plunger, uye plunger inosundira tappet pasi kusvika roller yakunguruka kusvika pazasi peCAM, uye plunger inodzokera kuzasi kwekumira kweplunger. Ndiko kuti, kana pombi yejekiseni yemafuta ichishanda, nekutenderera kwecamshaft, tappet uye plunger zvinodzokerana mugomba rematepi uye sleeve yeplunger zvakateerana pakati pepamusoro nepasi pakafa pakati pepombi.
