Thaum engineers qhia Alloy 6 qhov chaw, lawv tsis yog xaiv cov khoom siv xwb - lawv tau cog lus rau qhov ruaj khov nyob rau hauv 1,200 ° F, tiv thaiv sulfidation nyob rau hauv ib puag ncig roj qaub, thiab tsis kam rau siab rau microstructural inconsistency. Tias yog vim li cas muab los ntawm qhov tseeb Alloy 6 qhov chaw Hoobkas tsis yog hais txog tus nqi lossis lub sijhawm ua haujlwm ib leeg. Nws yog hais txog seb koj lub tsev twj tso kua mis yuav muaj sia nyob 25,000 cycles ntawm 8,000 psi - lossis seb koj cov cobalt alloy nozzle erodes ua ntej commissioning.
Vim li cas AMS 5387 Tsis yog Ib Daim Ntawv Qhia Tshwj Xeeb xwb
Peb tau pom peb qhov ua tsis tiav hauv Alloy 6 Cheebtsam: grain ciam teb tawg tom qab kev kho cua sov, tsis sib haum xeeb thermal expansion ntawm cov cam khwb cia thiab machined aav, thiab nto degradation thaum lub sij hawm kawg milling. Tag nrho cov kab rov qab mus rau ib lub hauv paus ua rau - fragmented txheej txheem tswj. AMS 5387 xav tau kev sib txuas nruj ntawm kev sib txuas ntawm cov khoom sib txuas, kev daws teeb meem rau lub sijhawm so, thiab ntau lub tswv yim ntawm kev siv txoj hauv kev. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb khiav tag nrho cov saw hauv tsev: peev casting ntawm T800-qib cobalt-nickel billets, CNC machining ntawm 5-axis kab rov tav mills nrog real-time thermal them, thiab tom qab machining HIP (kub isostatic nias) qhov twg yuav tsum tau. Tsis muaj handoffs. Tsis muaj batch-rau-batch guesswork. Peb tau lees paub txhua yam tiv thaiv ASTM E112 grain loj, ASTM E384 microhardness, thiab ASME B16.34 cov txheej txheem ntsuas siab - tsis yog ntawm kev tshuaj ntsuam zaum kawg, tab sis tom qab roughing, semi-tiav, thiab tiav dhau.
Qhov twg "Kev Cai" txhais tau tias Engineering, Tsis yog Geometry xwb
Qee tus neeg muag khoom kho kev cai Alloy 6 qhov chaw raws li CAD cov ntaub ntawv nrog kev ua siab ntev. Peb kho lawv raws li kev ua haujlwm. Lub piston twj tso kua mis lub tog raj kheej vaj tse tsis yog txhais los ntawm nws tus ID / OD - nws tau txhais los ntawm nws cov kev sib txuas hauv cov dej txias li cas cuam tshuam nrog thaj chaw muaj kev ntxhov siab thaum lub sijhawm thauj khoom thauj mus los. Tias yog vim li cas peb cov txheej txheem quoting pib nrog GD&T tshuaj xyuas - tsis kos kev lees paub. Peb chij cov teeb meem muaj peev xwm xws li: cov phab ntsa nyias nyias nyob ze cov ntsiab lus siab tshaj tawm cov kua nkag, cuam tshuam ntawm kev kho cua sov distortion thiab bearing seat runout, los yog cov cuab yeej tsis zoo rau kev siv sab hauv contour milling. Xyoo tas los, peb tau rov tsim kho lub winch center ncej cov menyuam rau lub EU-based engineering tsheb OEM - tsis txhob txiav nqi, tab sis kom tshem tawm 0.0015 ″ radial runout drift pom tom qab 400 teev ntawm kev siv teb. Qhov kho? Txav mus rau lub datum siv thav duab thiab hloov los ntawm xuab zeb casting mus rau peev-cam khwb cia preforms nrog tighter li-cam khwb cia phab ntsa thickness tswj. Cov txiaj ntsig: 92% txo qis hauv kev xa rov qab.
Vertical Integration Koj tuaj yeem ntsuas - Tsis yog thov xwb
"Vertically integrated" txhais tau tias tsis muaj dab tsi tshwj tsis yog tias koj tuaj yeem taug qab nws. Nov yog qhov zoo li hauv pem teb khw:
- Khoom siv traceability: Txhua AMS 5387 billet nqa tag nrho cov ntawv xeem ntsuas-xws li Co, Cr, Ni, Mo, Fe, C, Si, Mn, W, thiab N cov ntsiab lus - thiab txuas mus rau thawj tus xov tooj cua sov los ntawm cov neeg muab ntawv pov thawj
- Txheej txheem xauv-hauv: Sand casting pwm yog CNC-machined los ntawm txhuas qauv; peev casting ciab qauv yog 3D-luam tawm los ntawm validated STLs nrog ± 0.02 hli raug; tag nrho CNC cov kev pab cuam tau ua kom qhuav-khiav simulation thiab thawj-kab tshuaj ntsuam xyuas ua ntej hlau txiav
- Kev soj ntsuam nrujKev ntsuas CMM suav nrog qhov ntsuas kub-paub qhov ntsuas ntawm 20 ° C ± 1 ° C; optical profilometry kuaj Ra ≤0.4 μm ntawm qhov chaw sib khi; helium xau kuaj pom tseeb ntawm kev ncaj ncees ntawm 1 × 10⁻⁹ mbar·L / s rau kev sib koom siab-tseem ceeb
Qhov no tsis yog over-engineering. Nws yog li cas peb tuav ± 0.005 hli txoj hauj lwm kam rau ua ntawm 12-qhov flange qauv hla 320 hli diameters-thiab xa rov qab tau cov txiaj ntsig hla 150-unit ntau lawm khiav.
Kev xa khoom thoob ntiaj teb tiag-tsis muaj kev cuam tshuam
Yog lawm, Alloy 6 qhov chaw siv sijhawm ntev dua los ua. Tab sis "ntev" yuav tsum tsis txhob txhais hais tias "tsis paub tseeb." Peb cov kev ua haujlwm ntshiv suav nrog kev teem caij tsis pub dawb rau kev ua haujlwm tseem ceeb, kev cog lus ntawm cov khoom siv raw khoom ob leeg kom tsis txhob muaj cov saw hlau qeeb, thiab cov qauv tsim qauv uas tsis sib tw nrog lub peev xwm ntau lawm. Rau North American hydraulic OEMs, lub sijhawm ua haujlwm nruab nrab rau AMS 5387 lub twj tso kua mis yog 14 lub lis piam - los ntawm PO mus rau chaw nres nkoj - tsis hais qhov loj me. Rau cov neeg Esxias sab hnub tuaj xav tau T800 alloy plugs nrog nitrided nto, nws yog 10 lub lis piam, nrog rau tag nrho cov ntaub ntawv xa tawm digitally ua ntej xa lub cev. Peb tsis cog lus tias "ceev tshaj plaws." Peb cog lus * meej *. Vim tias thaum koj tus neeg siv khoom lub sijhawm ua haujlwm nyob ntawm lub rooj zaum cobalt alloy, qhov tseeb tsis zoo rau muaj - nws tsuas yog qhov tshwj xeeb uas tseem ceeb.
Yog tias koj qhov project tom ntej no suav nrog Alloy 6 qhov chaw Hoobkas kev sib koom tes-txawm yog rau AMS 5387 twj tso kua mis, cobalt alloy nozzles, los yog tsis-tus qauv T800 cam khwb cia-machined sib dhos-pib nrog engineering alignment, tsis RFQ xa. Tus khub zoo tsis yog ua raws li cov qauv. Lawv cia siab tias yuav tsis ua haujlwm ua ntej thawj nti ya mus.
