New Fuel Injector Nozzle Dsla143p1535 0433175456 OE 2854608 504091505 for Fuel Injector 0445120057

1. Tembiricha yemafuta mugap pakati petsono vharafu yekubatanidza zvikamu:

Kana vharafu yetsono ichidzokororwa, iyo kinetic simba inorasika neshear inoyerera friction pakati petsono valve vaviri uye gap mafuta inoshandurwa kuita kupisa simba, uye gaka.

Tembiricha yefirimu yemafuta inokwira zvishoma nezvishoma, uye mafuta anozowedzera kana tembiricha yakwira, kuitira kuti pave nekuwedzera kudzvanywa pafirimu remafuta mugedhi.

munda, huwandu hwekuremerwa kwefirimu remafuta hunowedzera, chiitiko ichi ndicho chinokonzera kupisa.Kana kuyerera kweshear kusingatariswe, kuyerera kwemafuta kunoderedzwa nekuda kwemadziro viscous resistance.Kana vharafu yetsono yakamira kana kufamba nekumhanya kwakaderera, kupera kwekumanikidza kwemafuta kunoshandurwa kuita simba rekupisa.Munguva pfupi, kupisa kwakaoma kuendesa kumadziro akasimba, saka inorerutswa seadiabatic process.

2. Kubuda mugomba remhete yevharuvhu yetsono:

Iyo tsono yevhavha yekubatanidza yakavharwa nemafuta firimu mune gap, uye ukobvu hwefirimu remafuta hunenge 2.μm.Iri rudzi rwemicron mhete gap rinoshandiswa zvakanyanya mukudzvanya-kudzvanya uye nekumhanya-kusheedzera chisimbiso.Kuyerera kwakasimba kweshear inoumbwa.Kukura kwegepa revharuvhu yetsono idiki kwazvo.Inovimba nedhiziri kuti iwane kuzvigadzika.Kana ichiyerera mune iyo micron-level gap, viscosity yemafuta edhiziri yakakura, uye nhamba yeReynolds idiki.inogona kuonekwa sezvikamu.

3. Radial deformation yekubatanidza vheji yetsono:

Sezvo kudzvinyirirwa kwegadziriro yemafuta ekufambisa kunowedzera, groove yekuchengetedza mafuta uye sliding surface clearance yemusangano wevhavha yetsono inotarisana nemutoro mukuru.Iyo inokonzeresa deformation yeaslastic yekubatanidza vharafu yetsono, inoshandura radial firimu ukobvu kugovera kweiyo firimu remafuta mugomba pakati peiyo tsono yekubatanidza vharafu, uye nekudaro inokanganisa hunhu hwekuisa chisimbiso chekubatanidza tsono.
