Izingxenye ze-Auto Fuel Injector Diesel Injection 4903472 ye-Cummins Auto Fuel Common Rail Injector

Ukuze kutholwe isimo sangempela sokuhlanzeka kukaphethiloli ezingxenyeni ezifanele zesistimu kawoyela wesitimela, amasampula kawoyela asensimini akhishwa edepho yesitimela izikhathi eziningi ukukala usayizi nenani lezinhlayiya zokungcola eziqukethwe kuphethiloli.Isilinganiso senziwe kusetshenziswa isihlaziyi sakamuva se-High Precision Particle Measurement System (PPMS) esikhiqizwe yi-KLOTZ, Germany.Ibanga lokutholwa lalisuka ku-2 kuye ku-100 μm.Imiphumela yokulinganisa ingavezwa ngokwenani lezinhlayiya ezinobukhulu obuhlukahlukene.

Qinisekisa ukuhlanzeka kokufakwa kukaphethiloli ethangini lamafutha esitimela.Edepho yesitimela, uwoyela ongahluziwe ongaphansi komhlaba ungcoliswa kakhulu ipayipi ngaphambi kokuba ufinyelele kusihlungi sikaphethiloli ongahluziwe.Okuqukethwe kwezinhlayiya ezinkulu kuphakama kakhulu, futhi izinhlayiya ezingaphansi kwe-15μm ziyancipha.Enqubweni yokugcina uwoyela omusha, ukungcoliswa kwezinhlayiyana kuwoyela kuvame ukuhlangana.Isibonelo, izinhlayiya ezingaba ngu-10 μm emafutheni zizokwakha kancane kancane i-50 ~ 200 μm ukungcola kwezinhlayiyana ezinkulu ngemva kokuba amafutha egcinwe isikhathi esithile.Ngesikhathi esifanayo, amafutha anezici ze-hydrophilic, ukuze inqubo yokugcina amanzi ikhule kakhulu, futhi amanzi kuphethiloli ayingozi empilweni yesevisi yepompo yomjovo kanye ne-injector;Futhi ngenxa yokuthi uphethiloli uqukethe ingxenye engu-S, uyingxenye ye-asidi, ukugqwala kwepayipi likawoyela, ukugqwala nokugqwala kwepayipi lensimbi bese kungcolisa uphethiloli.Uma uphethiloli uxhumeke ngokuqondile ku-locomotive kulesi simo, isihlungi sikaphethiloli esinokunemba okwanele kokuhlunga ngeke sithengeke;Uma ukunemba kokuhlunga kuncishisiwe, kuzophazamisa kakhulu ukusebenza okuvamile nempilo yesevisi yephampu yomjovo kaphethiloli kanye nomjovo.
