Common Rail Valve F00VC01015 Rau Diesel Injector 0445110059 rau koob txhaj tshuaj

"Cov qauv piv txwv" metallographic qauv: metallographic qauv ntawm cov hlau impurity thaiv yog ferrite.

Txiav txim siab qhov chaw ntawm cov hlau impurity blockage los ntawm cov qauv kev sib piv.

"Cov qauv piv txwv" metallographic qauv: metallographic qauv ntawm cov hlau impurity thaiv yog ferrite.

Cov qauv metallographic ntawm "cov qauv piv txwv" yog raws li hauv qab no:

A.Lub metallographic qauv ntawm lub twj tso kua mis lub cev ntawm lub siab-siab twj tso kua mis yogα cov tshuaj tov + acicular eutectic silicon;

B. Cov qauv metallographic ntawm lub plunger, nws cov qauv metallographic yog martensite + granular carbide;

C. Cov qauv metallographic ntawm lub tes tsho plunger, cov qauv metallographic nto yog martensite + khaws cia austenite;

D. Cov qauv metallographic ntawm lub plhaub txhaj tshuaj, uas yog flaky pearlite + loj heev thiab reticular ferrite.

E. Needle valve metallographic qauv, nws cov qauv metallographic yog martensite + band

F. Cov qauv metallographic ntawm rab koob valve lub cev, nws cov qauv metallographic yog martensite + granular carbide;

G. Cov qauv metallographic ntawm lub siab-siab tubing yog ferrite.

Los ntawm qhov kev sib piv saum toj no, cov qauv metallographic ntawm cov yeeb nkab roj siab yog zoo ib yam nrog cov hlau impurity blockage, ob qho tib si yog ferrite, uas qhia tau hais tias qhov blockage yog cais tawm ntawm cov roj yeeb nkab siab, thiab tom qab ntawd txiav txim siab qhov qhov chaw ntawm cov hlau impurity blockage. Thaum kawg, nws tau pom zoo tias thaum teeb tsa lub tshuab hluav taws xob diesel, qhov deburring thiab ntxuav ntawm cov kav dej uas siv cov roj hluav taws xob siab yuav tsum tau ua kom muaj zog, thiab tau txais txiaj ntsig zoo.

Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam kev lag luam thiab kev siv zog ntawm kev lag luam kev sib tw, cov khoom lag luam uas muaj kev sib tw muaj zog yuav tsum muaj cov txiaj ntsig zoo tshaj plaws ntxiv rau cov nqi, thiab tseem ceeb tshaj, yuav tsum muaj cov ntsuas kev ntseeg tau zoo thiab cov nqi qis hauv kev siv. Yog li ntawd, kev txhim kho qib kev ntseeg siab ntawm cov khoom yog qhov xav tau ntawm kev sib tw ua lag luam thiab ib qho ntawm cov khoom tsim nyog rau kev sib tw.
