Thaum engineers xav tau precision hlau qhov chaw uas yuav tsis poob nyob rau hauv 300 bar hydraulic siab - los yog nyob rau hauv corrosive oilfield ib puag ncig - lawv tsis pib nrog ib tug Google nrhiav rau "kev nqis peev casting Hoobkas." Lawv pib nrog ib qho teeb meem: lub valve xau ntawm 180 ° C, lub twj tso kua mis vaj tse tawg tom qab 4,200 teev ua haujlwm, lossis cobalt alloy nozzle eroding sai dua li qhov kwv yees. Qhov ntawd yog qhov kev paub tiag tiag hauv ntiaj teb cais cov neeg xa khoom muaj peev xwm los ntawm cov neeg uas tsuas yog ua tau raws li cov qauv ntawm daim ntawv.
Vim li cas cov khoom coj tus cwj pwm tseem ceeb dua li cov lej hauv phau ntawv
Peb tau pom ntau txoj haujlwm qeeb - tsis yog los ntawm lub sijhawm ua haujlwm, tab sis los ntawm metallurgical mismatch. Ib tus neeg siv khoom ib zaug tau teev tseg "stainless steel" rau lub tsev muaj zog piston twj tso kua mis. Ib feem dhau qhov kev soj ntsuam qhov ntev thiab ntsuas ntsev-txhaj tshuaj... tom qab ntawd tawg thaum lub sijhawm ua haujlwm. Hauv paus ua rau? Standard 316 tsis txaus. Thermal cycling thiab abrasive slurry xav tau ASTM A494 Qib CW6MC-ib tug duplex cobalt-nickel alloy nrog tswj delta ferrite cov ntsiab lus. Qhov ntawd yog qhov sib txawv ntawm kev ua raws cai thiab kev muaj peev xwm.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsis kho cov alloys li cov khoom. Nws pab neeg tshuaj xyuas cov ntaub ntawv pov thawj * ua ntej * quoting - tsis yog cov npe qib, tab sis cov xov tooj cua sov tiag tiag, tensile curves, thiab intergranular corrosion test reports. Thaum koj xaj AMS 5387 cobalt alloy 6 Cheebtsam, koj tau txais traceability mus rau electrode yaj batch. Tsis muaj kev hloov pauv. Tsis muaj "sib npaug" kwv yees. Tsuas yog cov ntaub ntawv sib xws thoob plaws txhua qhov ntau ntawm T800-based nozzles, plugs, lossis lub tog raj kheej liner.
Qhov twg Casting Precision ntsib Machining Control
Kev nqis peev casting ib leeg tsis tuaj yeem lav ± 0.02 hli roundness ntawm 120 mm bore - tshwj xeeb tshaj yog nyob rau hauv cobalt superalloys uas harden unpredictably thaum txias. Tias yog vim li cas kev sib koom ua ke ntsug tsis yog kev lag luam buzzword ntawm no; Nws yog tib txoj kev los tuav GD&T callouts zoo li txoj hauj lwm kam rau ua Ø0.05 hli rau mounting flanges ntawm twj tso kua mis foundations.
Lawv qhov chaw ISO-raws li kev lag luam casting * thiab * ntau-axis CNC machining nyob rau hauv ib lub ru tsev. Tsis muaj handoffs. Tsis muaj kev sib koom ua ke reboots ntawm foundry thiab tshuab khw. Thaum lub winch center ncej cov menyuam xav tau kev ruaj ntseg ntawm lub ntsej muag * thiab * micron-theem phau ntawv xov xwm concentricity, tib pab pawg neeg ua haujlwm saib xyuas ob qho tib si txheej txheem - thiab kho cov kev kho cua sov raws li qhov tseeb raws li kev ntsuam xyuas microstructure, tsis yog cov kab kos hluav taws xob.
Lub voj kaw ntom ntom no piav qhia vim li cas lawv lub siab li qub tau ua tiav lub rooj zaum rov qab tuaj yeem qis dua 0.1 cc / min ntawm qhov ntsuas siab-tsis muaj kev cia siab rau theem nrab lapping lossis xaiv sib dhos.
Yuav ua li cas "Quality Assurance" tiag tiag zoo li nyob rau hauv lub khw pem teb
"Tshuaj xyuas raws ISO 2768" txhais tau tias tsis muaj dab tsi yog tias CMM sojntsuam tsis tau kov koj qhov tshwj xeeb. Ntawm lub tuam txhab peev casting no, qhov zoo tsis yog qhov rooj zaum kawg - nws tau kos: cov ntaub ntawv raw cov ntaub ntawv pov thawj nrog spectrographic tsom xam, nyob rau hauv-kev ntsuam xyuas ntawm cov theem tseem ceeb (piv txwv li, plhaub thickness ua ntej dewaxing, core alignment ua ntej pouring), thiab zaum kawg functional testing siv calibrated hydraulic test rigs - tsis yog huab cua lwj.
Txhua qhov cobalt alloy ships nrog tag nrho traceability: kub tooj, casting ntau, machining cav, nto tiav Ra qhov tseem ceeb, thiab hardness nyeem ntawm peb qhov chaw radial. Cov neeg siv khoom hauv North America thiab Europe niaj hnub tshuaj xyuas cov ntaub ntawv no - thiab nrhiav tsis muaj qhov tsis sib xws hauv cov ntaub ntawv rau ASME B16.34 lossis PED 2014/68 ua raws.
Kev cia siab tiag tiag rau qhov nyuaj
Cia peb hais ncaj qha: qhov no tsis yog tus nqi qis, cov khoom ntim siab rau cov khoom lag luam. Lawv lub zog yog nyob rau hauv qhov chaw uas tsis ua hauj lwm, kev nyab xeeb, los yog kev cai rau txim - zoo li cov twj tso kua mis uas tsis yog-tus qauv rau subsea tswj systems los yog kev cai-zoo li nozzles rau high-temperature chemical dosing.
Lub sijhawm ua thawj coj qhia txog qhov kev tsom xam. Prototypes nkoj hauv 4-6 lub lis piam - tsis yog vim cov cuab yeej qeeb, tab sis vim lawv siv tau cov qauv kev simulation tawm tsam lub cev tensile tuav * los ntawm koj thawj zaug *. Kev txiav txim nruab nrab-ntev (50-500 pcs / xyoo) xauv rau hauv tus nqi ruaj khov thiab xa cov qhov rais kom meej vim tias lawv tsis txhob muaj qhov tsis sib xws ntawm kev sib koom tsim muaj peev xwm.
Yog tias koj qhov project tom ntej no suav nrog cobalt-nickel alloys, nruj-siab-siab hydraulic vaj tse, lossis lub hom phiaj tseem ceeb cam khwb cia-machined hybrids, txoj cai peev casting Hoobkas yuav tsis yog kos duab kos duab. Nws yuav nug txog koj qhov kev ua tsis tau zoo tshaj plaws xyoo tas los - thiab qhia txog cov khoom lossis cov txheej txheem hloov pauv uas tiv thaiv nws.
Rau cov engineers uas ntsuas kev ua tiav hauv uptime, tsis yog khoom xa tuaj raws sijhawm, precision pib ntev ua ntej thawj ncuav. Nws pib nrog kev paub raws nraim li cas cobalt alloy coj hauv koj daim ntawv thov - tsis yog lwm tus cov ntaub ntawv.
