Siab -Zoo tooj dag	ZCuZn25Al6Fe3Mn4	Cu≈60%, Zn: 25%, Al: 6%, Fe: 3%, Mn: 4%	Superior lub zog thiab toughness, haum rau hnyav-load structural daim ntaub ntawv

1.2 Cov yam ntxwv ntawm Bronze Liners.

 

Hnav tsis kam thiab tsis tshua muaj kev sib txhuam: haum rau zawv zawg, reciprocating, thiab rotary motions

Muaj peev xwm thauj khoom siab: compressive zog ntawm 300-500 MPa, zoo tagnrho rau cov khoom hnyav

Tus kheej-lubricating: lead-muaj, graphite-impregnated, los yog roj-impregnated qauv enables roj- pluag / roj- ua haujlwm dawb

Corrosion tsis kam: tiv taus dej, roj, dej hiav txwv, tsis muaj zog acids, thiab alkalis

Kev poob siab, txo suab nrov, thiab tiv thaiv- qaug dab peg: tiv thaiv cov ntaub ntawv sau tseg

Cov thermal conductivity zoo heev: ceev cua kub dissipation, haum rau kev ua haujlwm tas mus li

 

2. Cov qauv kev teeb tsa & cov txheej txheem tsim khoom

 

Bronze liners yog tsim los ntawm cov txheej txheem precision los xyuas kom meej cov khoom zoo, qhov tseeb qhov tseeb, thiab qhov zoo ntawm qhov chaw, nrog rau cov qauv kev teeb tsa raws li cov kev xav tau:

 

Tes Tsho Lineers: Khoom cylindrical lub tes tsho (OD: 10–200 mm, ID: 8–190 mm, ntev: 15–500 mm), tsim los ntawm centrifugal casting, xuab zeb casting, los yog extrusion, ua raws li tig, sib tsoo, thiab honing kom tiav nto roughness Ra tsawg dua los yog sib npaug rau 0.8 μm.

 

Phaj Lineers: Phaj liners nyob rau hauv ntau yam thicknesses, siv nyob rau hauv daim ntawv thov nrog nto loads; Thickness: 3-200 hli. Txhua qhov loj me tuaj yeem hloov kho.

 

Split Bearing Liners: Ob-daim qauv tsim rau kev yooj yim installation / tshem tawm, siv loj - txoj kab uas hla (ID> 100 mm) thiab hnyav- daim ntawv thov thauj khoom (xws li steel dov mills, cav crankshaft bearings, thiab hydraulic xovxwm mills, thiab lwm yam).

 

Graphite-Inlaid Bronze Liners: Graphite plugs (3-15 mm inch) embedded in the bronze matrix to provide self- lubrication under oil-free or low-lubrication condition, mitigate friction and wear in heavy environments.

 

Hlau -Bronze Liners: Bimetallic qauv (steel thaub qab + bronze overlay, thickness: 0.5–2.0 mm), sib txuas steel lub siab lub zog nrog bronze's tribological zog, haum rau ultra- hnyav-load daim ntaub ntawv (Ntau tshaj los yog sib npaug rau 500 MPa).

 

 

3. Engineering Applications & Operating Considerations

 

Bronze liner daim hlauyog dav siv nyob rau hauv engineering machinery, engine & automotive, aerospace, shipping & marine, thiab pwm industries. Cov kev siv ntau yog raws li hauv qab no.

Hydraulic cylinders: Piston pas nrig liners, lub tog raj kheej bore liners (C93200, B505, C93700);

Pwm machinery: Qhia bushings, slider coj daim hlau (CuSn10P, B101, C90700);

Automotive / cav: Crankshaft bearings, txuas pas nrig bearings, valve qhia;

Cov khoom siv marine: Stern ncej liners, rudder bearings, seawater twj tso kua mis liners;

Engineering machinery: Excavator pin liners, crane boom pivot liners (siab- zog tooj dag, C95400);

Metallurgical khoom: Rolling zeb bearings, nruam casting tshuab liner (B1032, CuAl10Fe3);

Cov kev xav txog kev khiav hauj lwm: Bronze liners yuav tsum tau lubrication kom zoo (cov roj ntxhia, roj) kom ua tiav kev pab cuam lub neej; rau siab -kub los yog corrosive ib puag ncig, aluminium bronze los yog corrosion-resistant tin bronze yog pom zoo. Dimensional kam rau ua yog feem ntau tswj nyob rau hauv ISO H7-H8 rau sab hauv txoj kab uas hla thiab h8-h9 rau txheej kab los xyuas kom meej haum haum nrog mating Cheebtsam.
