Made in China Common Rail Fuel Injector 0 445 120 067 0445120067 yeBosch Diesel Fuel Injector Spare Part

Gomba-mhando yemafuta majekiseni anonyanya kushandiswa muinjini dzedhiziri dzine makamuri ekupisa majekiseni. Iwo akakamurwa kuita marefu uye mapfupi marudzi maererano nechimiro chemafuta jekiseni nozzle. Nhamba ye nozzles ndeye 1 kusvika ku8, uye dhayamita yemuromo inenge 0.15 kusvika 0.7 mm. Mufananidzo 1 unoratidza refu rekudzoka-gomba jekiseni remafuta rinoshandiswa muinjini yedhiziri, iyo ine vharafu yetsono, muviri wetsono yevharuvhu, tsvimbo yekusundidzira, chitubu chinodzora chitubu, dhizaini inodzora screw uye muviri wejojo ​​jekiseni. Iyo dhayamita yemuromo ndeye 0.35 mm, kona yespray cone i150, uye jekiseni rinomanikidza 17.5 MPa.

Iyo jekiseni jekiseni rehuni (kusanganisira vharafu yetsono nemuviri wetsono yevharuvhu), inozivikanwawo seyetsono valve pair, inogadzirwa nemhando yepamusoro alloy simbi (GCr15) uye inobatwa nekupisa uye sarudzo inogayiwa kuita mapatya, saka haigone kuve. interchanged. Iyo inoenderana nemvumo ndeye 0.001 kusvika 0.0015 mm. Izvo zvinodikanwa kuve nechokwadi kutsvedza kwakanaka uye hapana kudonha kwemafuta. Ivhavhavha yetsono ine maviri conical surfaces. Iyo yepasi conical surface inobatana neinopindirana yemukati conical pamusoro mumutumbi wevharuvhu, iyo inonzi sealing conical surface kuti iname mukati memukati wejekiseni; iyo yepakati conical pamusoro iri mu annular oiri mhango yemuviri wevharuvhu kuti imirire axial kusundirwa kwemafuta ekumanikidza kuita kuti tsono vharafu isimuke, iyo inonzi inomanikidza-inotakura conical pamusoro. Kumucheto kwepamusoro kwemuviri wevharuvhu yetsono kune annular mafuta groove uye gomba remafuta chiteshi, uye kumucheto kwepasi kune gango remafuta uye gomba rekupfapfaidza. Ivhavhavha yetsono inosungirirwa kumuviri wejekiseni nevhavha yakasimba. Dzvinyiriro inodzora chitubu inotsikirira vharafu yetsono pachigaro chevharuvhu kuburikidza netsvimbo yekusundidzira. Iyo yekubata kumeso pakati pevharuvhu yetsono netsvimbo yekusundidzira inzvimbo yakatenderedzwa, iyo inogona kudzivirira vharafu yetsono kubva pakuburitsa lateral kudzvanywa nekuda kwekukotama kwetsvimbo yekusundidzira. Iyo elastic simba yekumanikidza inodzora chitubu inogona kugadziridzwa neiyo pressure regulating screw, uye yakavharwa nekudzvanywa inodzora nut mushure mekugadzirisa. Nheyo yekushanda yeinjector yakavharwa inoratidzwa muMufananidzo 4-46. Iyo yakakwira-kudzvanywa dhiziri kubva kune jekiseni pombi inopinda mugomba remafuta kuburikidza negero remafuta mumuviri wejekiseni uye muviri wevharuvhu wetsono. Sezvo gomba rekupfapfaidza rakavharwa nevhavha yetsono, dhiziri yedhiziri mumhango inokwira nekukurumidza. Kana dhiziri ichishanda pamusoro pekumanikidza-inotakura koni pamusoro pevharuvhu yetsono yakakura kupfuura simba rekusimudzira rekumanikidza rinodzora chitubu, vharafu yetsono inokwira axially, gomba rekupfapfaidza rinovhurwa, uye iyo-yakanyanya-kudzvanywa dizeli inotanga kupfapfaidza mukati. kamuri yekupisa kuburikidza neburi rekupfapfaidza. Nekuda kwekugwinha-gwinha kwegomba rekupfapfaidza, dhiziri yakapfapfaidzwa inoumba mhute yakanaka uye inokurumidza kuumba musanganiswa unopisa nemhepo. Iyi jekiseni inoenderera mberi kusvika pombi yejekiseni yamira kugovera oiri, uye kana kudzvinyirirwa kweoiri muinjector mhango kwadzikira pane elastic simba yekumanikidza inodzora chitubu, vharanda retsono rinobva ravhara gomba rekupfapfaidza pasi pechiito chekumanikidza kudzora chitubu, uye jekiseni rinomira.

Kudzvinyirirwa kwejekiseni rejekiseni rakavharwa kunonyanya kuenderana nekutanga kurongedzerwa kwesimba rinogadzirisa chitubu. Naizvozvo, kugadzirisa preload yekumanikidza inodzora chitubu kunogona kushandura zvakananga saizi yekumanikidza jekiseni. Kana iyo screw inotendeudzirwa mukati, preload yechirimo inowedzera uye kudzvanywa kwejekiseni kunowedzera; ukuwo, jekiseni pressure inoderera. Iyo tsono yevharuvhu yekusimudza inogumira nechepasi pekupedzisira pamusoro peiyo jekiseni muviri uye preload yekumanikidza inodzora chitubu. Naizvozvo, iyo yakanyanya kusimudza yevhavha yetsono yeinjector ndeye 0.45mm kuve nechokwadi chekukurumidza kubviswa kwemafuta. Panguva yekushanda kwejekiseni, dhiziri shoma inobuda kubva pakati pevharuvhu yetsono nemuviri wevharuvhu, inoyerera ichidzokera kune dhiziri sefa kana tangi yemafuta kuburikidza nepombi yemafuta ekudzoka, uye panguva imwechete inozora nhengo dzevharuvhu yetsono. .
