Izindlela zokunakekela injini ye-diesel fuel injection pump

(5) Hlola imvume ye-camshaft njalo
I-axial clearance ye-camshaft yepompo yomjovo kaphethiloli iqinile kakhulu, ngokuvamile iphakathi kuka-0.03 no-0.15mm. Uma imvume inkulu kakhulu, umthelela wezingxenye zokudluliswa kwe-roller endaweni yokusebenza yekhamera izoba mbi nakakhulu, ngaleyo ndlela kwandise ukuguga kwangaphambi kwesikhathi kwendawo yekhamera futhi kushintshe i-engeli yokunikezwa kukawoyela kusengaphambili; ukucaciswa kwe-axial ngokweqile kanye ne-radial kwamabheringi e-camshaft kungase kubangele kalula ukuthi i-camshaft isebenze ngokungazinzile, induku yokulungisa inani likawoyela inyakaze, kanye nenani lokunikezwa kukawoyela lishintshe ngezikhathi ezithile, kwenze injini kadizili ingasebenzi kahle. Ngakho-ke, kuyadingeka ukuhlola njalo kanye nokulungiswa. Lapho imvume ye-axial ye-camshaft inkulu kakhulu, ingalungiswa ngokungeza ama-shims ezinhlangothini zombili; lapho imvume ye-radial inkulu kakhulu, ngokuvamile kuyadingeka ukuyishintsha kufakwe entsha.

(6) Njalo hlola isimo sokuvala somhlangano wevalvu yokukhipha uwoyela emshinini
Ngemuva kokuthi iphampu yomjovo kaphethiloli isisebenze isikhathi eside, kungenziwa isinqumo esinzima mayelana nokugqokwa kwe-plunger kanye nesimo sokusebenza sephampu kaphethiloli ngokubheka isimo sokuvala se-valve yokukhipha uphethiloli, okuzuzisa ukunquma. izindlela zokulungisa nokulungisa. Ngesikhathi sokuhlola, qaqa amapayipi kawoyela anengcindezi ephezulu yesilinda ngasinye, bese umpompa uwoyela ngepompo yesandla kawoyela wephampu yokuletha uwoyela. Uma kukhona uwoyela ogelezayo ephuma emajoyintini epayipi likawoyela phezulu kwephampu yokujova uwoyela, kusho ukuthi ivalvu yokukhipha uwoyela ayivalwanga kahle (impela, izokonakala futhi lapho isiphethu sevalvu yokukhipha uwoyela siphuka. isimo siyenzeka). Uma kunokuvaleka kahle kwamasilinda amaningi, iphampu yomjovo kaphethiloli kufanele ilungiswe kahle futhi inakekelwe, futhi izingxenye ezilinganayo kufanele zishintshwe.
