Thaum cov tshuab ua lag luam xav kom tsis muaj kev cia siab rau qhov tsis ua haujlwm - cov twj hydraulic khiav ntawm 350 bar, cov rooj sib tham sab nrauv tawm ntawm cov dej hiav txwv thiab H₂S, los yog winch shafts enduring cyclic torsional loads - cov khoom muaj kev ntseeg siab tsis yog qhov tshwj xeeb. Nws yog qhov sib txawv ntawm lub sijhawm uptime thiab thaum muaj xwm txheej ceev. Tias yog vim li cas engineers nyob rau hauv North America, lub teb chaws Yelemees, thiab Singapore nce qhia qhov chaw ntawm lub HT300 Hoobkas: tsis yog ib tus neeg muab khoom lag luam, tab sis raws li kev koom tes nrog kev ntsuas rau lub hom phiaj tseem ceeb ntawm kev ua haujlwm hlau.
Vim li cas "HT300" tsis yog tus lej qauv xwb-Nws yog tus txheej txheem kos npe
Lub npe HT300 tshwm rau ntawm lub siab lub cev, lub twj tso kua mis piston lub tog raj kheej, thiab cobalt alloy nozzles xa mus thoob ntiaj teb. Tab sis nws tsis yog arbitrary. HT300 hais txog kev kho cua sov uas siv tau + machining raws tu qauv tsim dua 12 xyoo ntawm kev ua kom zoo nkauj cam khwb cia hlau microstructure rau qhov seem stability nyob rau hauv thermal cycling. Peb tau pom cov neeg siv khoom hloov los ntawm tus qauv EN-GJS-400-15 castings mus rau HT300-qib hlau thaum lub tog raj kheej lub tog raj kheej warped tom qab 8,000 teev ua haujlwm - txawm tias dhau qhov kev kuaj CMM thawj zaug. Lub hauv paus ua rau? Uncontrolled pearlite-to-ferrite piv nyob rau hauv as-cast matrix. HT300's tswj lub voj voog annealing nruj qhov kev hloov pauv mus rau ± 0.8% hla cov khoom siv - txheeb xyuas ntawm optical metallography thiab hardness mapping, tsis yog Brinell nyeem xwb.
Tsis muaj kev cuam tshuam kev ua haujlwm ntawm Alloy - Qhov twg AMS 5387 ntsib tiag-World Machining
Nug ib lub khw hauv pem teb engineer txog machining AMS 5387 cobalt-nickel alloy: chatter, cuab yeej hnav, ua hauj lwm hardening. Ib tus neeg siv khoom hauv Texas tau tshaj tawm txog 47% seem ntawm cov khoom siv cobalt uas siv cov pa carbide inserts thiab coolant-los ntawm spindles. Lawv txoj kev daws tsis tau nrawm dua - nws tau rov xav txog tag nrho cov kab ke. Ntawm lub Hoobkas HT300, AMS 5387 qhov chaw tau txais kev ua haujlwm ua ntej kev ntxhov siab (1,050 ° C / 4 teev / argon cua), ua raws li kev tiv thaiv kev ruaj ntseg ntawm -196 ° C ua ntej CNC hla dhau. Peb siv polycrystalline pob zeb diamond (PCD) cov cuab yeej nrog 3 ° tsis zoo rake kaum sab xis - tsis yog vim nws kim, tab sis vim nws tshem tawm cov microcracking subsurface uas ua rau qaug zog ntxov ntxov hauv cov twj tso kua mis siab. Qhov no tsis yog theoretical. Txhua T800-raws li nozzle nkoj nrog tag nrho batch traceability: cub tawg ID, txias tus nqi nkhaus, thiab post-machining ultrasonic soj ntsuam daim ntawv qhia.
Vertical Integration Uas Tau Txais Kev Tswj - Tsis yog Kev Lag Luam xwb
"Vertically integrated" txhais tau tias me me tshwj tsis yog nws daws teeb meem tiag tiag. Xav txog cov twj tso kua mis rau subsea booster systems. Ib qho European OEM xav tau ISO 13715-raws li GD&T ntawm 210 kg xuab zeb casting-nrog qhov tseem ceeb datum nta tuav rau ± 0.05 hli tom qab machining. Lawv cov khoom lag luam yav dhau los outsourced casting thiab machining rau cais cov neeg muag khoom. Qhov tshwm sim? 38% ntawm thawj-kab lus ua tsis tiav kev sib koom ua ke metrology vim tsis suav-rau pwm hloov pauv thiab cov khoom lag luam tom qab tshem tawm tsis sib xws. Lub Hoobkas HT300 tuav ob qho tib si hauv ib qho chaw ISO 9001-tso ntawv pov thawj: peev casting rau nyias-walled seem, xuab zeb casting rau cov qauv loj hauv paus, tom qab ntawd tsib-axis machining nrog cov txheej txheem laser soj ntsuam. Qhov tseem ceeb, lawv pub CMM cov ntaub ntawv rov qab rau hauv kev kho cov qauv-kaw lub voj hauv qab 72 teev. Tsis muaj handoffs. Tsis muaj txim-hloov. Tsuas yog kwv yees repeatability.
Dab tsi Engineers xav tau tiag tiag - Tsis yog Daim Ntawv Qhia Cog Lus
- GD&T validation ua ntej txiav hlau: Peb tshuaj xyuas koj cov duab kos rau cov kev pheej hmoo-tshwj xeeb tshaj yog thaum cov ntaub ntawv siv cov khoom siv los ntawm cov cam khwb cia substrates. Pom 12 qhov kev sib tsoo tsis muaj ntaub ntawv nyob rau hauv ib tus neeg siv khoom hydraulic manifold tsim thaum lub sijhawm tshuaj xyuas.
- Cov ntaub ntawv hloov pauv pob tshab: Yog tias ASTM A494 Qib CD4MCu poob qis ntawm cov tshuaj chloride pitting tsis kam, peb thov UNS R31233 (T800) nrog cov ntaub ntawv kuaj corrosion-tsis yog cov ntaub ntawv xwb.
- Lean kev xa khoom tsis muaj lean zoo kev lag luam tawm: Nruab nrab-ntim xaj nkoj hauv 18-22 hnub. Tsis yog vim cov ces kaum raug txiav - tab sis vim tias cov cua kub kho qhov cub khiav ntawm qhov kev kwv yees txij li kev saib xyuas, thiab cov kab tiav siv qhov ntsuas qhov roughness ntawm qhov chaw.
Kev ntseeg tau pib ntev ua ntej qhov seem tawm ntawm lub tsev rau khoom. Nws pib nrog kev qhuab qhia metallurgical, txuas ntxiv los ntawm geometric tseeb, thiab xaus nkaus xwb thaum cov khoom xa tawm nws lub neej kev pab cuam - nyob rau hauv load, nyob rau hauv siab, nyob rau hauv kev cia siab. Qhov ntawd yog HT300 Hoobkas tus qauv. Tsis yog raws li kev thov. Raws li qhov ntsuas tau.
