Lachin OEM koutim Nerjaveèi impeller papèdi sir envèstisman pwosesis Association.
Eleman alyaj baz yo nan nenpòt nikèl-baz oswa Distribisyon envestisman asye pur yo se chromium, nikèl, ak molybdène (oswa "moly"). Twa konpozan sa yo pral detèmine estrikti grenn Distribisyon an ak pwopriyete mekanik epi yo pral enstrimantal nan kapasite Distribisyon an pou konbat chalè, mete, ak korozyon.
Nerjaveèi gen yon kontni chromium minimòm de 10.5%, ki fè li pi rezistan nan anviwònman likid korozif ak oksidasyon. Sepandan, sa a se pa absoli. Envèstisman asye purDistribisyon yo se "korozyon ki reziste" lè yo itilize nan anviwònman likid ak vapè pi ba pase 1200 ° F (650 ° C) ak "chalè ki reziste" lè yo itilize pi wo a tanperati sa a.
Avantaj nan eleman Distribisyon Envestisman:
- Ekselan ak lis sifas fini
- Sere tolerans dimansyon.
- Fòm konplèks ak konplike ak fleksibilite konsepsyon
- Kapasite yo jete mi mens Se poutèt sa yon eleman Distribisyon pi lejè
- Seleksyon lajè nan metal jete ak alyaj (fèr ak ki pa fèr)
- Bouyon pa obligatwa nan konsepsyon mwazi yo.
- Diminye bezwen pou machin segondè.
- Fatra materyèl ki ba.
