Thaum engineers xav tau ib kev cai poob ciab casting Hoobkas rau qhov chaw uas yuav tsum tuav ± 0.02 hli kam rau ua nyob rau hauv 350-bar hydraulic siab, lawv tsis hu rau cov foundries. Lawv hu cov khw muag khoom nrog cobalt alloy cua sov-kho cov ntaub ntawv ntawm cov ntaub ntawv, CMM cov ntawv ceeb toom stamped los ntawm ISO 9001 auditors, thiab muaj kev xa khoom AMS 5387 twj tso kua mis vaj tse rau Tier-1 oilfield cov chaw muab kev pab hauv Houston thiab Aberdeen. Qhov ntawd yog qhov kev ua haujlwm tiag tiag - tsis yog lus lag luam.
Vim li cas "Kev Cai" txhais tau ntau dua li daim duab kos
Poob ciab casting tsis yog kev cai vim koj xa STEP cov ntaub ntawv. Nws yog kev cai thaum lub foundry cuam tshuam tsim kev pheej hmoo ua ntej kev pib siv. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau pom peb qhov rov ua tsis tiav cov ntsiab lus hauv cov neeg siv khoom xa tawm valve lub cev tsim: ua ntej, nyias-phab ntsa hauv qab 4.2 hli uas tawg thaum lub sij hawm tom qab nrum kev ntxhov siab; thib ob, dig muag sab hauv radii nyob rau hauv R1.5 uas ntxiab ceramic plhaub residue; thib peb, GD&T callouts qhia qhov profile ntawm qhov chaw yam tsis tau txhais cov ntaub ntawv ua ntej-ua rau kev ua haujlwm tsis zoo hauv piston twj tso kua mis. Peb chij cov no thaum lub sij hawm kev ntsuam xyuas engineering - tsis yog tom qab casting tsis lees paub. Qhov ntawd yog li cas "kev cai" dhau los ua kev kwv yees, tsis muaj kev cuam tshuam.
Tiag tiag-lub ntiaj teb Alloy tuav, Tsis muaj ntaub ntawv thov
Cobalt-nickel alloys zoo li T800 thiab AMS 5387 tsis machined-lawv tau coaxed. Lawv thermal conductivity yog 1/6th ntawm 304 stainless. Lawv ua hauj lwm-hardening npaum li cas spikes tom qab 0.15 mm ntawm txiav qhov tob. Tus qauv carbide ntxig shatters ntawm thawj kev sib cuag. Peb siv PVD-coated ceramic cov cuab yeej, dej txias txias ntawm 42 bar siab, thiab txwv axial qhov tob mus rau 0.08 hli ib zaug. Qhov no tsis yog txoj kev xav. Nws yog vim li cas peb cov cobalt alloy nozzles muaj sia nyob 18 lub hlis nyob rau hauv high-ceev slurry twj thaum cov neeg sib tw ua tsis tiav ntawm 5 lub hlis. Peb taug qab txhua qhov kev sib tw hardness nkhaus, qhov loj me me, thiab kev sib cais sib cais-vim microstructure txiav txim siab lub neej qaug zog, tsis yog lub zog tensile xwb.
Vertical Integration Koj tuaj yeem ntsuas
Feem ntau cov chaw muag khoom outsource casting, machining, lossis xov. Qhov ntawd ua rau muaj qhov dav dav. Cov qauv siv quav ciab tsis sib xws CNC fixture hnav. Kev kho cua sov distortion tsis them nyiaj hauv qhov kawg milling. Ntawm peb lub chaw Qingdao, ib pab neeg muaj cov saw hlau tag nrho: peev casting → kev ntxhov siab-relief annealing → 5-axis CNC contouring → HVOF txheej → xau kuaj. Rau lub piston twj tso kua mis lub tog raj kheej vaj tse, qhov no txhais tau tias tag nrho cov runout nyob qis dua 0.015 hli hla 320 hli ntev - txheeb xyuas los ntawm laser tracker, tsis yog CMM xwb. Tsis muaj handoffs. Tsis txhob liam ua si. Tsuas yog traceable txheej txheem tswj los ntawm wax txhaj tshuaj mus rau zaum kawg soj ntsuam daim ntawv qhia.
- Cov khoom siv raw tau lees paub rau ASTM A975 / AMS 5737 nrog rau tag nrho cov ntawv xeem ntawv
- Kev kuaj xyuas hauv cov txheej txheem: lub plhaub tuab pov thawj, siv quav ciab qauv qhov ntsuas qhov ntsuas, ua ntej kev kho cua sov hardness daim ntawv qhia
- Qhov kawg validation: helium xau kuaj rau 1 × 10⁻⁹ mbar·L / s, nto roughness Ra ≤ 0.8 μm ntawm lub ntsej muag tseem ceeb sealing, ntsev-txhaj tshuaj tiv thaiv ≥ 1,000 teev ib ASTM B117
Yam uas cov neeg siv khoom xav tau tiag tiag—Tsis yog Daim Ntawv Qhia Cog Lus
Cov neeg saib xyuas kev yuav khoom nug peb lo lus nug - thiab tau txais cov lus teb tsis meej nyob rau lwm qhov:
"Koj puas tuaj yeem tuav txoj haujlwm tseeb ntawm rau Ø8.5 hli qhov nyob hauv 0.01 hli mus rau lub datum tsim rau ntawm qhov chaw nrum?" Yog - yog tias lub kaum sab xis casting yog ≥ 1.2 ° thiab cov datum nto yog machined tiaj ua ntej lub qhov drilling. Peb yuav qhia koj txog kev tsim khoom siv.
"Dab tsi yog koj lub sijhawm ua haujlwm rau 12 daim ntawm AMS 5387 ntsaws nrog cov xov xov tsis zoo?" 28 hnub los ntawm kev pom zoo kos duab. Tsis yog "4-6 lub lis piam." Tsis yog "nyob ntawm cov khoom muaj." Peb Tshuag T800 billets thiab tuav dual-qhov kev pom zoo nrog ob AMS-certified cobalt lwm tus neeg nyob hauv Suav teb thiab lub teb chaws Yelemees.
"Koj puas txhawb PPAP Qib 3 rau automotive hydraulic systems?" Yog lawm - nrog rau tag nrho DFMEA cov ntaub ntawv, cov txheej txheem khiav daim duab, thiab MSA cov kev tshawb fawb ntawm txhua yam tseem ceeb. Tsis yog ib daim ntawv teev npe xwb.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm qhov twg precision hlau qhov chaw raws li qhov tshwm sim tiag tiag. Thaum lub winch center ncej cov menyuam ua tsis tiav ntawm ntug dej hiav txwv crane, downtime nqi $ 220,000 / teev. Thaum lub siab valve tso rau hauv subsea tswj module, hloov yuav tsum tau ROV cuam tshuam ntawm 2,800 meters. Tsis muaj chaw rau "kaw txaus." Tias yog vim li cas cov neeg siv khoom rov qab - tsis yog rau tus nqi, tab sis rau qhov tseeb qhov tseeb, kev sib haum xeeb ntawm cov hlau, thiab kev sib koom ua haujlwm engineering tau ua rau txhua qhov kev tsocai. Lub sijhawm tom ntej koj qhia txog cov khoom siv rau kev kub siab, hnav siab, lossis kev pabcuam corrosion tseem ceeb, pib nrog kev tsim khoom - tsis yog geometry xwb. Koj lub hom phiaj kev ntseeg siab nyob ntawm nws.
