Pre-coated Resin Sand Castings rau Marines
Khoom siv
• Grey Hlau: Muab cov castability siab nrog kev puas tsuaj, ib txwm siv rau hauv cov khoom siv hauv hiav txwv thiab hauv cov khoom siv.
• Cov Hlau Hlau: Muaj kev cuam tshuam rau kev ua haujlwm siab nrog rau lub zog siab, uas yog tsim nyog nyob rau hauv cov ntaub ntawv ntawm high stressing machinery tivthaiv, piv txwv li, propeller hub los yog cav blocks.
• Aluminium Alloys: Lub teeb nyob rau hauv qhov hnyav thiab corrosion-resistant, castings nyob rau hauv txhuas yog siv nyob rau hauv qhov chaw uas yuav tsum tau kom phim siab zog nrog lightening, xws li cov qauv nkoj thiab cov twj tso kua mis.
• Bronze Alloys: Tsis tshua muaj kev tiv thaiv corrosive, tshwj xeeb tshaj yog nyob rau hauv dej ntsev, tsim nyog hauv fittings, kiv cua, marine valve qhov chaw.
Specifications
• Qhov hnyav: Castings muaj peev xwm los ntawm me me, precision qhov chaw mus rau loj, hnyav-duty Cheebtsam uas hnyav ob peb tons.
• Dimensional kam rau ua: Yuav kom ± 0.5mm yog nyob rau hauv ib txoj kev uas castings haum nyob rau hauv marine machinery thiab marine systems.
• Nto tiav: Pre-coat cam khwb cia nto yog muab nrog ib tug siab nto tiav nrog tsawg kawg nkaus kev kho mob tom qab cam khwb cia.
• Mechanical Properties: Castings yog tsim los nrog lub zog tensile siab, cuam tshuam tsis kam, nrog rau kev tiv thaiv kev qaug zog, uas yog qhov tseem ceeb hauv kev siv marine raws li cov khoom tawm hauv qhov hnyav ib puag ncig.
Cov txheej txheem ntau lawm
1. Qauv Tsim: Cov qauv zoo heev ntawm cov khoom siv yog tsim los ntawm cov khoom siv ruaj khov xws li hlau lossis yas.
2. Txheej: Tus tsim kuj yog coated nrog ib txheej uas muaj pre-coated tov nrog xuab zeb uas tsim ib tug ruaj khov, tawv lub tsho tiv no.
3. Moulding: Cov qauv yog ib puag ncig nrog ib txheej ntawm cov khoom siv cob-coated thiaj li tsim tau cov pwm uas tiv taus cua sov.
4. Kev kho: Cov pwm kuj tau rhuab nyob rau hauv thiaj li yuav harden lub resin, tuav ib tug ruaj khov thiab raug casting txheej txheem.
5. Hlau Pouring: Cov hlau yog nchuav rau hauv pwm nyob rau hauv nws daim ntawv molten, piv txwv li cov duab ntawm tus qauv.
6. Cua txias thiab tso tawm: Cov hlau yog txias thiab cia solidified ua ntej qhib pwm nyob rau hauv thiaj li yuav casted yam khoom.
7. Kev ua tiav: Cov cam khwb cia yog machined, deburred, thiab ntxuav raws li qhov tsim nyog thiaj li ua tiav cov lus qhia meej.
Kev xeem thiab kev soj ntsuam zoo
• Kev tshuaj xyuas qhov muag: Cov cam khwb cia yog ua tib zoo tshuaj xyuas ntawm nws qhov chaw rau qhov tsis zoo, tawg, lossis tsis xws luag.
• Dimensional Measurement: Cov castings tau khaws cia nrog qhov loj me me nrog cov tshuab tshwj xeeb.
• Mechanical Testing: Cov kev cuam tshuam tsis kam, hardness, thiab tensile lub zog yog kuaj kom paub tseeb tias cov kav dej hauv marine yog siv tau.
• Kev Xeem Tsis Muaj Kev Ua Phem (NDT): Ultrasonics thiab X-rays yog ob qho tib si siv rau hauv kev sib tw los tshuaj xyuas cov teeb meem sab hauv uas yuav cuam tshuam rau kev ua haujlwm hauv ib feem.
Ntsiab nta
• Corrosion Resistance: Cov castings yog tsim nyog rau marine daim ntawv thov, yog ntsev-resistant, yog li ua rau lawv ua hauj lwm raws li tau zoo raws li check.
• Siab Durability: Lub pre-coated castings los ntawm resin xuab zeb tsis yog tsuas yog ruaj ntxiv rau qhov ruaj khov nyob rau hauv high-pressure aggressive marine ib puag ncig nrog sib txawv kub.
• Precision Engineering: Muab lub ntsej muag zoo nrog kev ruaj ntseg siab uas txo qis kev ua haujlwm ntxiv.
• Versatility: Haum thoob plaws ntau yam ntawm marine daim ntawv thov los ntawm nkoj fittings, propellers, rau cav spares, thiab twj tso kua mis.
• Txo cov haujlwm tom qab Casting: Qhov kev txhim kho saum npoo zoo txo cov haujlwm uas yuav tsum tau ua tiav thaum casting tiav.
Kev lag luam kev siv
Pre-coated resin xuab zeb castings yog qhov tseem ceeb hauv ntau yam kev siv dej hiav txwv, suav nrog:
• Nkoj Cav: Cav blocks, lub tog raj kheej taub hau, crankshafts.
• Marine Propulsion System: Ntiv nplhaib tsav, kiv cua ncej, gearcases.
• Pump Components: Lub twj tso kua mis yog ib yam li bilge twj tso kua mis.
• Marine Fittings Valves: Valves thiab piping fittings nrog lub cev khoom uas yog corrosive-resistant.
• Yam Khoom: Brackets, structural Cheebtsam, thiab hull txhawb nqa.
Ntim thiab Cia
Txhua qhov casting yog ntxuav kom huv si, tshuaj xyuas, thiab ntim nrog cov khoom uas tiv thaiv nws los ntawm kev puas tsuaj hauv kev thauj mus los thiab hauv kev tuav. Cov castings yog warehoused nyob rau hauv climatic qhuav mob nyob rau hauv thiaj li yuav tsis degenerate los yog corroded ua ntej daim ntawv thov.
Kev xa khoom
Thaum kuaj xyuas zoo, castings tau ntim nrog kev saib xyuas thiab xa tawm thoob ntiaj teb. Txhua qhov kev txiav txim raug xa nrog cov ntaub ntawv tsim nyog raws li daim ntawv pov thawj tshuaj xyuas nrog rau daim ntawv pov thawj ua raws.
