Inodiwa Factory Mutengo Wekutumira Valve 504660 ye Simms Minimec Mapombi

Injector pombi ndiyo 'moyo' weinjini kana paine kutadza kuchaita kuti injini yese isashande Yakanyanya-kudzvanywa kwepombi yekupa pombi chikamu chakakosha cheyakanyanya-kumanikidza yakajairika jekiseni renjanji yejekiseni yepamusoro-yekumanikidza kuti ipe yakagadzikana uye inoenderera. high-pressure fuel injector pump plunger movement mukuita kwepamusoro-frequency kufamba kwevhavha yekubuda inokanganisa kuvimbika uye kugadzikana kwevharuvhu kana yakakwira-pressure mafuta. kudonha kubva panzvimbo yekuvharisa ꎬ kusakwana kwehutsi hwemafuta ꎬ common rail system. Kana iyo yakanyanya kudzvinyirirwa mafuta ichidonha kubva pachisimbiso chepamusoro, kudzvanywa kwemafuta mune yakajairika njanji system hakuna kukwana, zvichikonzera kusakwana kwejekiseni kudzvanywa kwejekiseni uye kushomeka kweatomisation, izvo zvinotungamira kune yakaderera injini simba kana kutadza kutanga. Mupepa rino, kuitira kugadzirisa dambudziko repamusoro-soro yekuvhara chisimbiso pamusoro pekutadza kuvharika kunokonzerwa necavitation muvhavhavha yekubuda, tinoongorora chimiro chevhavhavha yekubuda uye nekugadzirisa chimiro chevhavha kuburikidza neinogumira-element simulation kuverenga uye kuyedza kusimbisa. kuti iyo yakagadziridzwa dhizaini inoshanda mukugadzirisa dambudziko recavitation.

Ivhavha yekubuda iri pachikamu chepamusoro cheplunger yepombi yejekiseni uye yakabatanidzwa kune yakakwirira-pressure accumulator chamber. Ivhavha yekubuda ivhavha yenzira imwe chete uye mafuta anogona kungopfuura mune imwe nzira uye kune imwe nzira, iyo inogona kuvhara mafuta ekumanikidza. Chimiro uye maitiro ekushanda kwevhavha yekubuda ndeaya: kana cam inotenderera ichienda kune yakadzika chikamu cheiyo cam profile, iyo plunger inofamba ichidzika uye yakashata kudzvanywa kunogadzirwa mukamuri yeplunger. Kana mutsauko wekumanikidza pakati peinopinza nekamuri yeplunger inosvika pakumanikidzwa kwekuvhura kwevhavha, zvino, kana iyo inlet spool ichidzika ichidzika, vharafu inovhurwa uye mafuta achapihwa mupombi yekupa nenzira yekupinza spool. Kana cam inotenderera ichienda kumutsara wakasimudzwa plunger kuenda kumusoro kweiyo yekamuri yekushanda vhoriyamu inova diki kamuri yekumanikidza inokwira nekukurumidza kana iyo kamuri yepamusoro yekumanikidza kumusoro inovhura iyo yekuburitsa vharafu inoputira yakakwira-kumanikidza kwemafuta kuyerera kune yakajairika njanji pombi apo plunger kubva pasi kuenda kuzasi. iyo yekumusoro inomira kupomba process yapera Injector pombi plunger inodzokorodza process discharge vharafu spool kazhinji chinja mafuta kudzvanywa shanduko muhombe-kudzvanywa chisimbiso nzvimbo iri inokonzeresa kune cavitation inotungamira kune yekuburitsa vharafu sealing surface material spalling sealing surface. Oiri vharafu yekuisa chisimbiso pamusoro pechinhu chinoputika chisimbiso chisimbiso chepamusoro kutadza kuvharira laxity yepasi-yakavakirwa simba rekugadzira dizeli injini yakaitika mune akati wandei jekiseni pombi discharge vharafu cavitation kutadza kutsungirira bvunzo maawa mazana mashanu epamusoro-kudzvanywa chisimbiso pamusoro peiyo inoburitsa valve zvinhu zvinoputika, kuvhara. kukundikana dambudziko riri kure pasi pezvinowanzoshandiswa jenareta upenyu zvinodiwa
