Vavu Yojambulira Wanjanji F00VC01015 Ya Dizilo Injector 0445110059 ya Singano Yobaya

"Chitsanzo chofananira" mawonekedwe a metallographic: mawonekedwe a metallographic a chipika chonyansa chachitsulo ndi ferrite.

Dziwani komwe kumachokera kutsekeka kwachitsulo poyerekezera ndi zitsanzo.

"Chitsanzo chofananira" mawonekedwe a metallographic: mawonekedwe a metallographic a chipika chonyansa chachitsulo ndi ferrite.

Kapangidwe ka metallographic "chitsanzo chofananira" ndi motere:

A.Mapangidwe a metallographic a pampu ya pampu yapamwamba kwambiri ndiα yankho lolimba + silicon ya acicular eutectic;

B. Mapangidwe a metallographic a plunger, mawonekedwe ake a metallographic ndi martensite + granular carbide;

C. Mapangidwe a metallographic a manja a plunger, mawonekedwe a metallographic ndi martensite + osungidwa austenite;

D. The metallographic dongosolo la jekeseni chipolopolo, amene flaky pearlite + yaikulu ndi reticular ferrite.

E. singano vavu metallographic dongosolo, kapangidwe ake metallographic ndi martensite + gulu

F. Mapangidwe a metallographic a thupi la singano la valve, mawonekedwe ake a metallographic ndi martensite + granular carbide;

G. Mapangidwe a metallographic a machubu apamwamba kwambiri ndi ferrite.

Kupyolera mu kuyerekezera pamwamba, kapangidwe metallographic wa mkulu-anzanu chitoliro mafuta n'zogwirizana ndi wa zitsulo zonyansa blockage, onse amene ndi ferrite, zomwe zimasonyeza kuti blockage ndi detached ku chitoliro mkulu-anzanu mafuta, ndiyeno amatsimikiza gwero la kutsekeka kwachitsulo chosayera.Potsirizira pake, akulangizidwa kuti pokonza makina opangira mafuta a dizilo, kuchotsa ndi kuyeretsa mapaipi amafuta othamanga kwambiri omwe amagwiritsidwa ntchito ayenera kulimbikitsidwa, ndipo zotsatira zabwino zapezeka.

Ndikukula kosalekeza kwachuma chamsika komanso kukulirakulira kwa mpikisano wamsika, chinthu chomwe chili ndi mpikisano wamphamvu chiyenera kukhala ndi ziwonetsero zabwino kwambiri zogwirira ntchito kuphatikiza pamitengo yamitengo, ndipo koposa zonse, ziyenera kukhala ndi zisonyezo zabwino kwambiri zodalirika komanso kulephera kochepa komwe kumagwiritsidwa ntchito.Chifukwa chake, kuwongolera kudalirika kwazinthu ndikufunika kwampikisano wamsika komanso chimodzi mwazinthu zofunika kuti zinthu zikhale zopikisana.
