High Quality Diesel Fuel Injection Pump Plunger 9 411 085 006 9085-006 Injini Zvikamu 9411085006

Iyo plunger peya muinjini yedhiziri chikamu chinodyiwa. Kana ikatsiviwa pamadiro panguva yekuchengetedzwa kwejenareta yedhiziri, zvinotozokonzera tsvina. Naizvozvo, zvakakosha kugona nzira yekuzivikanwa kwayo.

Zvinoenderana nekurongeka kwepombi, pombi yeplunger inogona kukamurwa kuita radial plunger pombi uye axial plunger pombi. Iyo axis ye plunger yeaxial plunger pombi inofanana neaxis yedhiraivha shaft, nepo axis ye plunger yeradial plunger pombi iri perpendicular kune axis ye drive shaft. Pasinei nechimiro, nheyo inokosha yakafanana.

Basa reiyo plunger peya yedhiziri injini jekiseni pombi nderekuwedzera kudzvanywa kwedhiziri kuti isangane nezvinodiwa zvekudzvanywa kwejekiseni yeinjector nozzle uye kudzora huwandu hwemafuta uye nguva yekupa mafuta. Iyo plunger pair chinhu chakakosha mukusangana kwepombi jekiseni. Haifanire kunge iine chisimbiso chakanaka chete, asiwo yakanaka inotsvedza zvinhu. Kana iyo plunger yakanamatira kana yakanamatira, ichaita kuti rack inonetsa kufamba, kana kutotadza kufamba, uye mugadziri achakundikana.

Kukuvara kwepeyi yeplunger kunonyanya kupfeka, uye zvikamu zvekupfeka zvinonyanya kutariswa panzvimbo yekushanda yemuno, kureva kuti, zvikamu zvinoenderana zvemusoro weplunger uye plunger sleeve yemafuta inlet hole, kumucheto kweyakarerekera groove stop supply uye. kumucheto kwegomba remafuta ekudzoka. Nzira dzekuongorora uye chitupa ndeidzi:

(1) Kuongorora pamotokari.

① Mhosva yekuongorora nzira. Kupfeka kwepeyi yeplunger kune kukanganisa kukuru pane peturu yekupihwa pamberi pekona. Kana pombi yejekiseni yemafuta ikatanga kupa mafuta kunonoka, nguva yekufambisa mafuta inopera kare, uye kumanikidza kwemafuta hakuna kukwana, misa mota uye urove crankshaft kuti uteerere ruzha rwejekiseni remafuta. Kana usingakwanise kunzwa ruzha rwejekiseni remafuta, zvinoreva kuti plunger pair yakasakara uye inofanira kutsiviwa.

② Finger-top kunzwa nzira. Bvisa pombi yemafuta akanyanya-kudzvanya, isa throttle panzvimbo yepamusoro pekuisa mafuta, dzvanya chigunwe zvakasimba pamuromo wepombi yekubuda kwemafuta, wobva warovera crankshaft kugadzira pombi yemafuta kuti ipe mafuta kana kushandisa screwdriver kudzvanya. pombi tsoka. Kana mafuta emafuta akanyanya kukwirira uye chigunwe chakaoma kudzvinyirira, zvinoreva kuti plunger pair inogona kuramba ichishandiswa; kana mafuta emafuta asina simba, zvinoreva kuti plunger pair yakasakara uye inofanira kutsiviwa.

(2) Injector bvunzo nzira. Paunenge uchitarisa cylinder yeplunger, bvisa iyo yakanyanya-kudzvanywa pombi yemafuta woitendeudzira kune imwe kona, batanidza jekiseni rakajairwa (kumanikidza kwakagadziridzwa kusvika 19.6 MPa), ita jekiseni rinotarisa pasi, gadzirisa throttle pahuwandu hwemafuta. chinzvimbo, uye kukwenya crankshaft mushure mekudzvanya kuti utarise mamiriro eatomization ejekitori. Kana iyo atomization yakanaka, inoratidza kuti iyo plunger pair inogona kuramba ichishandiswa; kana jekiseni isingapfeki mafuta, inoratidza kuti plunger pair yakasakara uye mafuta epombi haana simba, uye haichagoni kushandiswa.

(3) Nzira yekuyera chombo. Shandisa gauji yekumanikidza ine huwandu hwe0-60 MPa, ibatanidze kune yakanyanya-kudzvanywa pombi yehumburu yejekiseni pombi, isa iyo throttle panzvimbo yepamusoro yekupa mafuta, crankshaft kujekesa mweya, uye rega geji. kudzvinyirira kunokwira kusvika ku24.5 MPa. Tarisa kudonha kwemafuta kudonha kumhanya pane iyo pressure geji. Kazhinji, inofanira kudonha kubva 24.5 MPa kusvika 14.7 MPa isingasviki 5-10 maminetsi kuti ive yakanaka.

(4) Nzira yekucherechedza. Shandisa ziso rakashama kana girazi rinokudza 4-10x kuti uone kana paine zviratidzo zviri pachena zvekupfeka, mitsetse yekubvisa, kana ngura makwapa pamusoro peiyo plunger, ingave mipendero yeoblique grooves uye migero yakatwasuka pamusoro weiyo plunger. dzakagomara kana kupepereswa, uye kuti plunger ine hurema hwakadai sekukotama kana kudhonzwa kwemusoro.
