Ububamba njani ubukhulu be-chrome plating yokuchaneka kwepiston rod machining

Intonga yepiston echanekileyo okwangoku isetyenziswa kumashishini amaninzi ukuya kwimveliso, kungenxa yokuba intonga yepiston isetyenziswa kakhulu, ke abantu bokukhethwa kwezinto zokuvelisa intonga yepiston kukwaqwalaselwa ngakumbi nangakumbi ekukhetheni izinto ezahlukeneyo zemveliso, emva koko ukuveliswa kwayo. ukusebenza kwepiston echanekileyo kunye neempawu zikwahlukile.

I-45 # intsimbi yintsimbi ye-carbon structural, ilungile ukubanda kunye nokusebenza okutshisayo, iipropati zoomatshini, amandla aphezulu.I-45 # intsimbi ekucimeni ngaphandle kokufudumeza, ukuqina okukhulu kune-HRC55 yabaqeqeshiweyo, kwaye emva konyango lobushushu, kwaye emva koko ukucima kunokufikelela kwi-HRC42-46, ukuze intonga yepiston echanekileyo ineempawu ezilungileyo zoomatshini kunye nobunzima.

I-40Cr yintsimbi ephakathi kwekhabhoni epholileyo, emva konyango olufanelekileyo lobushushu, unokufumana ubunzima obuhle, iplastiki.Kwaye inokuba neepropathi ezilungileyo ezibanzi zoomatshini emva konyango lobushushu, ukuqina okuhle kobushushu obuphantsi.Ukongeza, le ntsimbi ifanelekile kwi-cyanidation kunye ne-high frequency quenching unyango ukongeza kunyango lobushushu.

Intsimbi ye-GCr15 luhlobo lwesiqulatho se-alloy engaphantsi kwekhabhoni yekhromium ephezulu enentsimbi, enobunzima obuphezulu, emva kokuba unyango lobushushu lunokufumaneka emva kobunzima obuphezulu nobufanayo.Kwaye xa icinyiwe kunye nonyango oluphantsi lobushushu obuphantsi, lunokuba nobunzima obuphezulu, intlangano efanayo kunye neempawu eziphezulu zokudinwa kunye nokucaphuka komsindo.

I-Sus304 inokumelana ne-corrosion ephezulu ngokwentelekiso, inokuba kubushushu obuphantsi, ubushushu begumbi kunye nobushushu obuphezulu bubuplastiki obuphezulu kunye nokuqina kunye nokwenza ngcono ukubanda kunye nokuwelda.Ngenxa yokuba i-austenite yayo ayinalo utshintsho lwesigaba xa ishushu, i-piston rods echanekileyo ayinakuqiniswa ngonyango lobushushu kwaye inokuphathwa ubushushu ukuqinisa ukuxhathisa kwentsimbi.

Ubukhulu be-chrome plating yenkqubo ye-piston echanekileyo kufuneka igqitywe ngokudibanisa neyona nto.Kwi-piston rod chrome plating process, ubukhulu bomgca we-chrome bunobudlelwane obusondeleyo kunye nobunzima bomhlaba bentonga.Xa i-chrome plating isenziwa, oku kunokumiselwa ngokweemfuno zomthengi ukuze kuphunyezwe ukusebenza kakuhle komgangatho.
