Thaum koj lub twj tso kua mis hydraulic lub tsev tawg ntawm 450 ° C, los yog cobalt alloy nozzle tsis ua haujlwm nyob rau hauv lub voj voog thermal shock, "high-temperature resistant parts factory" nres ua lub sij hawm tshawb nrhiav - nws dhau los ua hnub kawg. Peb tau pom nws nyob rau hauv North American oilfield daim ntawv cog lus, nyob rau hauv European offshore valve retrofits, thiab thoob plaws cov teb chaws Es Xias desalination nroj tsuag: off-the-shelf Cheebtsam buckle. Dab tsi tuav tsis yog tsuas yog kev tiv thaiv tshav kub xwb - nws yog metallurgical sib xws, qhov ruaj khov tom qab cua sov, thiab xoom kam rau kev sib cais microstructural. Yog vim li cas engineers qhia-tsis yog cov ntaub ntawv-tab sis cov high-temperature resistant qhov chaw Hoobkas qab lawv.
Kev ua tau zoo hauv ntiaj teb pib ntev ua ntej machining. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua qhov AMS 5387 cobalt alloy pib nrog cov ntaub ntawv pov thawj raw khoom traceability-down rau cov xov tooj cua sov thiab daim ntawv qhia txog zeb. Peb tsis lees txais daim ntawv pov thawj "ua raws"; Peb txheeb xyuas cov qoob loo loj ntawm cov khoom xa tuaj siv ASTM E112 raws tu qauv. Vim li cas? Vim tias qhov sib txawv ntawm 5% hauv carbide dispersion tuaj yeem txiav lub neej kev pab cuam los ntawm 60% hauv cov twj tso kua mis siab. Nyob rau hauv ib qhov project tsis ntev los no rau German engineering tsheb OEM, peb in-house spectral tsom xam ntes tau ib tug marginal npib tsib xee ntsiab lus drift nyob rau hauv ib tug T800 alloy batch-ua ntej casting. Qhov kev tshawb pom ntawd tiv thaiv 120 qhov ua tsis tau zoo ntawm cov ncej ncej hauv cov tshuab winch ua haujlwm ntawm 520 ° C saum npoo kub thiab 120 MPa cuam tshuam.
Vertical kev koom ua ke tsis yog ib lo lus buzz ntawm no - nws yog li cas peb tswj qhov tseem ceeb tshaj plaws: theem hloov pauv tus cwj pwm thaum txias. Sand-cam khwb cia hlau vaj tse rau piston twj tso kua mis tau tswj kev ramp-down cycles hauv peb qhov chaw kho cua sov qhov cub-tsis yog outsourced. Qhov ntawd txhais tau hais tias kwv yees tau graphite nodule suav (ASTM A247 Chav Kawm 3), tsis sib xws hardness (220-260 HBW), thiab tsis muaj qhov seem ntawm kev ntxhov siab vim kev ua tsov rog tom qab CNC tiav. Meanwhile, peev-cam khwb cia cobalt alloy nozzles tau HIP'd (kub isostatic nias) tam sim tom qab-casting kom tshem tawm microporosity - tseem ceeb heev thaum phab ntsa thickness poob qis dua 2.3 hli thiab kev khiav hauj lwm siab tshaj 350 bar. Cov neeg siv khoom nug: "Koj puas tuaj yeem tuav ± 0.015 hli ntawm 320 hli cylinder vaj tse tom qab 3 teev ntawm 480 ° C?" Yog-vim peb validate thermal expansion coefficients ntawm cov qauv geometries ua ntej tag nrho cov khoom, tsis yog tom qab.
Qee qhov kev xav tias muaj peev xwm kub-kub tsuas yog los ntawm cov hlau tsis zoo. Tab sis peb pom ntau qhov ua tsis tiav los ntawm kev ua tsis zoo GD&T ua ntau dua li kev ua tsis ncaj ncees lawm. Lub siab lub cev lub cev yuav siv tus qauv F22 stainless hlau-tab sis yog tias nws lub rooj sib khi nto tsis muaj qhov tseeb tswj kev txheeb ze rau lub qia, qhov dej ntws tawm ntawm 300 ° C. Yog vim li cas peb qhov kev tshuaj xyuas tsis yog daim ntawv teev npe-tsav. Txhua qhov tseem ceeb tau txais kev pov thawj CMM tawm tsam tus qauv CAD thawj - tsis yog qhov nominal qhov ntev - thiab optical profilometry ntawm sealing ntsej muag kom paub meej Ra ≤ 0.4 µm tom qab passivation. Rau cov khoom tsis yog tus qauv T800, peb khiav lub voj voog thermal validation: peb lub voj voog tag nrho los ntawm ambient mus rau 550 ° C, tom qab ntawd kev ua haujlwm ntawm max ntsuas siab. Tsis muaj kev zam. Tsis muaj kev zam.
Yog tias koj tab tom nrhiav qhov kub-resistant qhov chaw koom tes nrog cov koom haum niaj hnub no, saib tshaj cov ntawv pov thawj ntawm phab ntsa. Nug: Lawv puas muaj lawv cov kev kho cua sov? Lawv puas tuaj yeem qhia koj cov duab microstructure los ntawm lub hli dhau los AMS 5387 ntau? Lawv puas tuaj yeem tshuaj xyuas koj GD&T callouts ua ntej hais - thiab chij qhov twg qhov kev zam nruj dua ntxiv tus nqi tab sis tsis ua haujlwm? QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm li no vim kev ntseeg tsis tau xa hauv lub thawv xa khoom. Nws tau tsim rau hauv txhua tus xov tooj cua sov, txhua qhov cuab yeej cuab tam, txhua cov ntaub ntawv tshuaj xyuas. Lub sijhawm tom ntej koj lub cev ua haujlwm kub, koj cov khoom yuav tsum tsis txhob muaj sia nyob - lawv yuav tsum ua. Qhov ntawd pib nrog xaiv leej twg tswj cov kev hloov pauv uas tseem ceeb.
