Thaum lub twj tso kua mis hydraulic tsis ua haujlwm nyob rau hauv cov roj av sab nrauv-los yog lub siab-siab valve ntes thaum lub sij hawm tseem ceeb cementing kev ua haujlwm-lub hauv paus ua rau feem ntau tsis tsim, tab sis cov khoom degradation. AMS 5387 Stellite qhov chaw tsis hnav maj mam. Lawv ua tsis tau tam sim ntawd: micro-cracks propagate nyob rau hauv cyclic thermal stress; carbide tes hauj lwm tawg nyob rau hauv abrasive slurry txaus; nto kev ncaj ncees ntog tom qab rov qab thermal cycling. Peb tau pom nws nyob rau peb lub tebchaws - hauv North Hiav Txwv subsea manifolds, Texas frac twj tso kua mis, thiab cov neeg Esxias sab hnub tuaj desalination boosters. Txhua lub sijhawm, qhov kev ua tsis tiav tsis yog random. Nws ua raws li tus qauv: qhov dav dav dhau ± 0.015 hli ntawm qhov chaw sib khi, poob ntawm Rockwell C62-65 hardness tom qab 4,200 teev ua haujlwm, lossis intergranular oxidation ntawm tshav kub-tshuaj lom los ntawm kev ua haujlwm tsis zoo tom qab ua haujlwm annealing.
Vim li cas AMS 5387 Stellite Parts Xav Tau Ntau dua li Kev Hloov Kho
AMS 5387 tsis yog tsuas yog cobalt-raws li alloy-nws yog lub tshuab metallurgical tsim rau kev ua haujlwm siab heev. Nws muaj pes tsawg leeg (64-68% Co, 27-31% Cr, 0.9-1.4% C, ntxiv rau Ni, W, Si, Mn) muab tshwj xeeb tsis kam rau galling, corrosion fatigue, thiab kub-kub oxidation. Tab sis qhov kev ua tau zoo hinges ntawm kev tswj hwm ntawm peb qhov sib txawv: as-cam microstructure homogeneity, machining-induced residual stress distribution, thiab qhov kawg deg kev ncaj ncees. Ib feem tshuab nrog cov dej txias tsis raug lossis cov cuab yeej txoj hauv kev yuav ua tau raws li GD&T kam rau ua-tab sis ua tsis tiav kev ntsuas kev vibration hauv 72 teev. Peb tau lees paub qhov no hla 112 qhov ntau lawm: 87% ntawm qhov ua tsis tiav ntawm qhov chaw ua haujlwm ntxov tau taug qab mus rau subsurface microcracking qhia thaum lub sijhawm ua tiav-tsis yog cov khoom siv tsis raug.
Qhov no yog vim li cas "hloov" yog kev dag ntxias. Cov neeg ua haujlwm xav tau dab tsi kev ua haujlwm txuas ntxiv: zoo tib yam thermal expansion coefficient, sib piv coefficient ntawm kev sib txhuam tawm tsam mating stainless Cheebtsam, thiab khaws cia compressive nto kev nyuaj siab mus rau 0.3 hli qhov tob. Qhov ntawd yuav tsum tau ntau tshaj qhov khoom nyoos bar Tshuag. Nws xav tau kev tswj cov txheej txheem casting (kev nqis peev casting nyiam rau cov geometries nyuaj), multi-axis CNC cov tswv yim uas txo cov cua sov tsim, thiab tsis muaj kev puas tsuaj pov thawj siv phased-array ultrasonics - tsis yog CMM checks.
Peb Qhov Tsis Sib Tham hauv AMS 5387 Stellite Part Supply
Cov neeg muag khoom feem ntau kho AMS 5387 raws li cov khoom lag luam tshwj xeeb. Lawv tsis ua. Nov yog yam uas cais lub luag haujlwm tseem ceeb ntawm cov khoom siv los ntawm kev sib pauv khoom:
- Cov ntaub ntawv traceability rau cov xov tooj cua sov - tsis yog daim ntawv pov thawj zeb xwb. Txhua batch peb txheej txheem nqa tag nrho spectrographic tsom xam, grain loj daim ntawv qhia (ASTM E112), thiab hardness mapping hla tsib ntu ntu. Tsis muaj kev zam.
- Machining parameters xauv rau daim ntawv thov physics. Rau piston twj tso kua mis lub tog raj kheej vaj tse, peb siv cryogenic txias nrog -70 ° C nitrogen pos huab thiab trochoidal cuab tam txoj kev-txo subsurface tensile kev nyuaj siab los ntawm 43% piv rau cov pa dej nyab coolant.
- Functional validation ua ntej ua zaub mov xa tuaj. Txhua qhov AMS 5387 Stellite tau sim simulated kev sim: 200-teev thermal cycling ntawm -20 ° C thiab + 250 ° C, tom qab ntawd los ntawm kev ntsuas kev sib tsoo ntawm 1.5 × kev ua haujlwm siab. Cov ntaub ntawv hla / tsis ua haujlwm yog kos rau hauv QR-coded traceability tag.
Qee tus yuav sib cav tias cov ntaub ntawv pov thawj cov khoom pov tseg tshem tawm kev pheej hmoo. Tab sis AMS 5387 qhov rhiab heev rau keeb kwm thermal txhais tau tias txawm tias ASTM F90-raws li billet tuaj yeem txhim kho qib sigma yog tias rov ua kom tsis raug thaum lub sijhawm ua haujlwm tsis zoo. Peb zam qhov no los ntawm kev sib koom ua ke ntawm kev kho cua sov rau hauv peb qhov kev ua haujlwm-kev daws teeb meem ntawm 1175 ° C ± 5 ° C, tom qab ntawd tswj cov cua txias ntawm ≤15 ° C / min - txheeb xyuas nrog cov thermocouples hauv cub hluav taws xob nkag rau hauv ASME BPE.
Qhov twg Standard Catalog Solutions poob luv
Off-the-shelf AMS 5387 Stellite qhov chaw tsis tshua haum rau lub ntiaj teb tiag tiag. Peb niaj hnub tau txais cov duab kos cim "ASME B16.34 Class 900" tsuas yog kom pom lub ntsej muag flange xav tau kev cai saum npoo ntawm lub ntsej muag rau kev foob tuav hauv high-viscosity polymer txhaj. Los yog "tus qauv" plug tsim uas tsis quav ntsej txog qhov tseeb yaig profile los ntawm 30% xuab zeb-laden kua-yuav tsum tau nyob hauv cheeb tsam tungsten carbide cladding ntawm ntug kev, tsis yog txheej txheej.
Peb cov lus teb tsis yog "peb tuaj yeem ua tau." Nws yog: "Ntawm no yog li cas peb tau sim cov duab geometry tiv thaiv koj qhov khiav nrawm, qhov loj me me, thiab lub voj voog ua haujlwm - thiab ntawm no yog qhov kwv yees hnav lub neej ntawm 90%, 75%, thiab 50% ntws tus nqi." Peb tau xa ntau tshaj 2,300 yam tsis yog AMS 5387 Stellite Cheebtsam - los ntawm cobalt alloy nozzles nrog laser-etched sab hauv swirl vanes rau winch center ncej rollers nrog asymmetric hardness gradients (HRC 64 ntawm load sab, HRC 52 ntawm tsav sab). Txhua qhov kev daws teeb meem pib nrog koj cov ntaub ntawv ua haujlwm - tsis yog peb cov ntawv teev npe.
Xaiv tus khub, tsis yog tus neeg muab khoom
Yog tias koj tom ntej no AMS 5387 Stellite qhov kev txiav txim hinges ntawm kev zam 72-teev downtime nyob rau hauv ib qho chaw deb, saib dhau lub sij hawm quotes. Nug: Lawv puas tuaj yeem rov ua dua koj qhov uas twb muaj lawm qhov chaw tiav Ra tus nqi hauv ± 0.05 µm? Lawv puas khaws cov qauv microstructural los ntawm txhua qhov cua sov rau kev sib piv?

QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm los ntawm qhov chaw no. Lawv cov ISO-raws li qhov chaw hauv Qingdao koom ua ke peev casting, 5-axis CNC machining, thiab nqus cua sov kho-tag nrho hauv ib lub ru tsev. Lawv tsis ua haujlwm rau AMS 5387. Lawv tsis lees txais "raws li yog" kos duab yam tsis muaj GD&T validation. Thiab lawv tsis xa khoom yam tsis muaj cov ntaub ntawv ntsuas kev ua haujlwm khi rau koj tus lej xaj xaj.
Tus nqi tiag tiag ntawm AMS 5387 Stellite feem tsis yog tus nqi them nqi. Nws yog qhov kev kaw tsis tau npaj tseg, qhov xwm txheej kev nyab xeeb los ntawm kev foob tsis ua haujlwm tam sim ntawd, kev puas tsuaj rau lub koob npe nrov los ntawm kev hloov dua tshiab. Xaiv cov neeg koom tes uas kho cov khoom siv cobalt alloy tsis yog cov khoom lag luam - tab sis raws li kev tsim kho txuas ntxiv ntawm koj lub hnab ntawv kev ntseeg siab.
