Kusankha pakatiufa zitsulo ndikufakawirikawiri ndi nkhani ya kukula kwa gawo kapena zofunikira zakuthupi. Zomwe zimagwiritsidwa ntchito kwambiri ndi zida zopangira aluminium, ma aloyi a magnesium ndi aloyi a zinki, ndi zotayira zamkuwa zamkuwa zitha kugwiritsidwanso ntchito.Monga fakitale imodzi yazitsulo yopanga zitsulo zopangidwa ndi zitsulo zopangidwa ndi zitsulo zopangira ufa ndi aluminium kufa kuponyera ku China, tidzasankha njira yabwino kwa inu!

Poyerekeza ndi magawo a ufa zitsulo ndizitsulo jekeseni akamaumba mbali, kukula kwa zinthu zoponya kufa ndizokulirapo. Pamene zofunika zotsatirazi ndi zofunika, ndi ufa zitsulo ndondomeko ndi abwino kwambiri:

1. Kulimba kwambiri, kulimba kwamphamvu kwa ma aloyi ena opangidwa ndi iron-based sintered ndikokwera kwambiri kuwirikiza katatu kuposa mphamvu yayikulu kwambiri ya aloyi otayira.
2. High kuvala kukana ndi mkulu antifriction ntchito, amene angathe kuthetsedwa ndi chitsulo-based ndi mkuwa-based sintered alloys impregnated ndi lubricating mafuta.
3. Kutentha kwakukulu kwa ntchito, komwe kungathe kuthetsedwa ndi zitsulo zopangidwa ndi chitsulo komanso zamkuwa zokhala ndi sintered alloys.
4. Zosagwirizana ndi dzimbiri, aloyi wopangidwa ndi mkuwa ndi chitsulo chosapanga dzimbiri amatha kukwaniritsa zofunikira.

Pakati pa zitsulo za ufa ndi kuponyera kufa, kuponyedwa kwa zinc kumatha kukhala m'malo mwa chitsulo.mankhwala ufa zitsulopansi pakugwiritsa ntchito kutentha kosaposa 65 digiri Celsius ndi mphamvu yapakatikati. Koma nthawi zambiri zitsulo za ufa zimakhala zabwino kwambiri.

Mitundu ya magawo a ufa zitsulo

1. Zigawo zamapangidwe

Magiya ndi mbali zosiyanasiyana zonyamula mphamvu zopangidwa ndi mkuwa, chitsulo, ma aloyi amkuwa, ma aloyi a aluminiyamu, ndi zina zambiri.

Sintered zitsulo-impregnated fani mafuta. Mabowo okhala ndi chitsulo ndi mkuwa okhala ndi porosity ya 15% mpaka 25% amadzazidwa ndi mafuta opaka mafuta.

Mkuwa-backed sintered aloyi mayendedwe. Woyamba ndi chitsulo kumbuyo ndipo wachiwiri ndi sintered mkuwa-aluminium aloyi.

DU, DX mayendedwe, etc.

Ntchito zamagawo am'magawo: magalimoto, zida zamakina, makina aulimi, makina a nsalu, zida, makina osokera, zida zamagetsi, ndi zina zambiri, injini zoyatsira mkati, magalimoto anjanji, makina azitsulo, zojambulira matepi, zojambulira makanema, ma micro-motor, etc.

2. Zigawo zokangana

Clutch zimbale kapena ananyema magulu etc. zopangidwa ndi zitsulo mochirikiza ndi chitsulo kapena mkuwa zochokera ufa nyimbo

Kugwiritsa ntchito magawo a Friction: zida zamagalimoto, ndege, akasinja, makina omanga, zida zamakina ndi makina amagetsi.

3. Zosefera ndi zinthu zina za porous

zosefera. Zinthu zooneka ngati chikho, zooneka ngati koni, zooneka ngati ndodo zopangidwa ndi mkuwa wozungulira, faifi tambala, chitsulo, chitsulo chosapanga dzimbiri, ndi ufa wina wachitsulo wokhala ndi pores yunifolomu.

Zinthu zozimitsidwa. Pali ndodo, mikwingwirima ndi machubu opangidwa ndi faifi tambala, nichrome, chitsulo chosapanga dzimbiri ndi zinthu zina zosagwira dzimbiri zokhala ndi porosity yofikira 50%.

Fiber zitsulo zopangidwa. Zapamwamba kwambiri (mpaka 80%) zopangidwa kuchokera ku ulusi wabwino wazitsulo.

Kugwiritsa ntchito zinthu zosefera ndi zinthu zina za porous: zomwe zimagwiritsidwa ntchito posefa mpweya ndi zakumwa zosiyanasiyana m'makampani opanga mankhwala, zida zamakina, ndege, magalimoto, injini zoyatsira mkati, ndi zina zotere, monga zosefera zachitsulo zokhala ndi porous m'zigawo za ndege, monga zigawo zoziziritsa mu ndege, mapanelo acoustic, zinthu zosefera pazolinga zapadera.
