Koj pom ntau RFQs rau Tribaloy qhov chaw, tshwj xeeb tshaj yog T400 thiab T800, thiab tam sim ntawd muaj kev sib cais. Qee lub khw pom nws tsuas yog lwm qhov nyuaj-fab alloy, lwm tus tau ntshai ntawm cobalt puag. Ob qhov kev xav tsis nco qab lub ntsiab lus. Nws tsis yog hais txog hardness lossis kub tsis kam; nws yog hais txog qhov tshwj xeeb hnav mechanism uas koj tab tom sib ntaus sib tua - nplaum hnav, galling, yam ntawd. Kuv tau pom ntau tus qauv tsim ua ntej rau T800 vim tias nws nyuaj dua, tsis quav ntsej tias T400 qhov kev tiv thaiv zoo dua tuaj yeem yog cov lus teb tiag tiag rau qhov poob siab-loaded foob nto. Lub npe nws tus kheej, Tribaloy T400, T800 qhov chaw, tuaj yeem yog cuab ntxiab, ua rau tib neeg xav tias lawv yog cov qib sib pauv tau ncaj qha. Lawv tsis yog.
Alloy Nws tus kheej - Ntau tshaj li ib daim ntawv teev cov ntaub ntawv
Ua hauj lwm nrog QSY ntawm lub tes tsho twj tso kua mis xyoo tas los yeej cemented qhov no. Qhov tshwj xeeb hu ua T800. Cov ntaub ntawv hais tias ~ 58 HRC, zoo heev. Tab sis thaum peb nkag mus rau hauv lub tswv yim machining nrog lawv pab pawg engineering, kev sib tham tsis yog hais txog kev nrawm thiab pub thawj zaug. Nws yog hais txog kev ncaj ncees casting. Nrog rau cov cobalt-chromium-molybdenum alloys, lub microstructure los ntawm cov txheej txheem casting - seb nws yog plhaub pwm los yog peev casting - dictates txhua yam uas tuaj tom qab. Tus qauv cam khwb cia tsis zoo txhais tau tias koj yuav caum cov tawv tawv hloov txhua hnub, thiab cov cuab yeej yuav raug tua.
Qhov ntawd yog qhov chaw nrhiav kev paub qhia. Piv txwv li, Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), piv txwv li, lawv peb lub xyoo caum hauv plhaub thiab peev casting txhais tau tias lawv yuav pom cov qauv solidification rau cov alloys ib txhiab zaus. Lawv paub qhov twg yuav tso rooj vag thiab risers rau Tribaloy T400 ib feem kom txo qis Laves theem tsim nyob rau hauv ib qho tseem ceeb hnav ib cheeb tsam. Koj tuaj yeem tsis tsuas yog CNC tshuab koj txoj kev tawm ntawm qhov phem casting. Ib feem yuav yog qhov tseeb, tab sis nws lub neej kev pabcuam yuav yog ib feem.
Kuv nco qab txog qhov ua tsis tiav ua ntej hauv kuv txoj haujlwm, nrhiav qhov yooj yim T400 ntxhua khaub ncaws los ntawm lub khw muag khoom siv tshuab. Lawv muab cov khoom lag luam bar, machined nws. Nws ntsia zoo tag nrho. Ua tsis tiav hauv daim teb hauv 200 teev. Cov khoom lag luam bar muaj cov qauv coj los ntawm cov txheej txheem dov; nws hnav unevenly kiag li. Zaj Lus Qhia: Rau qhov ua tau zoo, cov ntu no feem ntau yuav tsum muaj ze-net-puab cam khwb cia, ces precision machined. Daim ntawv pib yog ib nrab ntawm kev sib ntaus sib tua.
Machining - Tus nqi tiag tiag tsav tsheb
Qhov no yog qhov uas cov roj hmab tau raws txoj kev. Txhua leej txhua tus hais cov nqi khoom ib kilo rau Tribaloy, tab sis tus nqi tiag tiag yog nyob rau hauv lub toolpath. Nws tsis zoo li machining stainless. Nws ua hauj lwm-hardens aggressively. Yog tias koj tus nqi pub poob qis dhau lawm, koj tsuas yog polishing ntawm qhov chaw thiab ua kom nws dhau ntawm lub cuab yeej muaj peev xwm txiav. Koj xav tau kev teeb tsa nruj, qhov zoo rake geometries, thiab qee zaum koj tsuas yog lees tias carbide yuav yog khoom siv.
QSY txoj kev sib xyaw ua ke, tuav ob qho tib si casting thiab CNC machining hauv tsev, ua qhov sib txawv. Lawv tsis yog tsuas yog lub khw machining tau txais kev paub tsis meej casting. Lawv nrum nws, lawv paub nws lub hnab tawv tawv, lawv tuaj yeem npaj cov txheej txheem machining raws li. Rau ib tug complex Tribaloy T800 valve lub rooj, lawv yuav ntxhib tshuab tom qab casting, ces siv ib tug kev nyuaj siab nyem, ces rov qab los rau tag machining. Cov kauj ruam nruab nrab ntawd yog qhov tseem ceeb rau kev ruaj ntseg ntawm qhov ntev tab sis feem ntau hla los ntawm cov khw tsuas yog tab tom nrhiav los ua ib nti.
Coolant yog lwm subtlety. Koj xav tau kev kub siab, ntim dej txias, tsis yog rau cov cua sov xwb, tab sis kom ntxuav cov chips uas ntse thiab tuaj yeem rov ua dua. Peb kawm qhov no txoj kev nyuaj ntawm kev khiav ntawm T400 bushings. Cov cuab yeej lub neej yog abysmal mus txog thaum peb hloov mus rau ib qho tshwj xeeb-lubricity coolant thiab qhib lub nozzle siab. Ib qho kev nthuav dav me me, tab sis nws ua ob peb lub cuab yeej lub neej.
Daim Ntawv Thov Pitfalls thiab Tsim Kev Sib Tham
Engineers nyiam qhia Tribaloy rau qhov tsis yog vim li cas. High hnav tsis kam yog qhov tsis meej. Kuv tau thawb rov qab rau cov qauv tsim qhov twg cov plasma-txheej txheej lossis txawm tias cov hlau tawv tawv yuav tau txaus ntawm ib feem peb ntawm tus nqi. Qhov chaw qab zib rau T400 thiab T800 yog qhov tseeb uas koj muaj hlau-rau-hlau zawv zawg sib cuag yam tsis muaj lubrication txaus, lossis nyob rau hauv ib puag ncig corrosive-coj. Xav tias lub twj tso kua mis plungers, foob rings nyob rau hauv cov tshuaj tov khoom, los yog tej yam khoom noj khoom haus extruder Cheebtsam uas koj siv tsis tau lubricants.
Ib rooj plaub tshwj xeeb nrog QSY los rau hauv siab. Ib tus neeg siv xav tau tag nrho T800 rotor rau lub twj tso kua mis kab noj. Loj heev, kim. Tom qab tshuaj xyuas daim ntawv thov, peb pom zoo kom tsim ib qho kev sib xyaw ua ke: steel rotor core nrog Tribaloy T400 stellite overlays ntawm lub siab hnav lobes. Nws ua tau zoo ib yam rau hom kev hnav tshwj xeeb, muaj sia nyob ntawm corrosion, thiab txiav cov nqi tiv thaiv ntau dua 40%. Cov neeg siv khoom tsuas yog tsis tau xav tias ib feem tuaj yeem yog hybrid. Qhov ntawd yog tus nqi ntawm kev ua haujlwm nrog tus neeg tsim khoom uas nkag siab txog cov khoom siv lub luag haujlwm, tsis yog nws cov specs xwb.
Lwm qhov pitfall yog haum thiab clearance. Cov alloys muaj qhov sib txawv coefficient ntawm thermal expansion dua li cov carbon steel vaj tsev lawv feem ntau ua ke nrog. Yog tias koj tsis suav rau qhov ntawd, dab tsi haum ntawm chav tsev kub khi lossis loosens ntawm kev khiav hauj lwm temp. Nws suab yooj yim, tab sis kuv tau pom nws ua rau muaj kev puas tsuaj loj. Ib txwm muaj qhov sib txawv thermal tsom xam.
Kev tsim khoom thiab kev sib raug zoo ntawm tus neeg muag khoom
Koj tsis yuav cov khoom no tawm ntawm lub txee. Koj tsim lawv nrog tus neeg muag khoom. RFQ pob yuav tsum muaj ntau tshaj li ib daim duab. Nws xav tau cov ntsiab lus: kev khiav hauj lwm kub, mating khoom, hom kev txav (rotating, oscillating), muaj cov tshuaj los yog particulates. Qhov no tso cai rau tus neeg koom tes ua haujlwm zoo li QSY tuaj yeem hais qhia lwm txoj hauv kev lossis kev ua kom zoo dua.
Lawv lub vev xaib, https://www.tsingtaocnc.com, qhia lawv ntau yam hauv cov alloys tshwj xeeb, uas yog qhov pib zoo. Tab sis lo lus nug tiag tiag yog koj tsis tuaj yeem pov qhov no? Nws ua li cas koj tau pov ib yam zoo li no ua ntej? Lawv cov keeb kwm ntev nrog cobalt thiab npib tsib xee-raws li alloys qhia tias lawv tau tsim ib qho kev paub txog kev tsim qauv, kev kho cua sov, thiab kev ua haujlwm tsis zoo rau cov ntaub ntawv tsis yooj yim no. Qhov kev paub hauv tsev kawm ntawv yog qhov koj them nyiaj tiag tiag.
Lub sijhawm ua thawj coj yog lwm qhov tseeb. Zoo Tribaloy T800 qhov chaw tsis ceev. Nruab nrab ntawm cov qauv / pwm tsim, lub voj voog casting, ua tau HIPping (kub isostatic nias) rau qhov tseem ceeb ceev, kev kho cua sov, thiab qeeb, ceev faj machining, koj tab tom saib lub sijhawm ntsuas hauv lub lis piam, tsis yog hnub. Kev npaj rau qhov ntawd yog ib feem ntawm cov txheej txheem kev tshaj lij.
Xaus Unscientific Postscript
Yog li, thaum koj saib tom ntej ntawm daim duab hu rau Tribaloy, nres. Puas yog T400 rau tawv tawv tiv thaiv kev cuam tshuam, lossis T800 rau qhov siab tshaj plaws hardness tiv thaiv puas? Puas yog qhov tsim nyog tiag tiag, lossis nws puas yog spec luam tawm los ntawm qhov project dhau los? Thiab qhov tseem ceeb tshaj plaws, koj puas tham nrog tus neeg muag khoom uas pom tias nws yog cov khoom siv los ua kom zoo li tus, lossis raws li kev daws teeb meem uas yuav tsum tau ua?
Qhov sib txawv txiav txim siab tus nqi, lub sijhawm ua haujlwm, thiab kev ua haujlwm. Nws yog qhov sib txawv ntawm ib feem uas ua tau raws li cov ntawv luam tawm thiab cov khoom uas muaj sia nyob hauv daim teb. Kuv qhov kev paub dhau los, txhawb nqa los ntawm kev sib koom tes nrog cov tuam txhab kev koom ua ke, yog qhov kev vam meej nrog cov alloys nyob rau hauv kev kho tag nrho cov txheej txheem - los ntawm yaj mus rau zaum kawg grind - raws li ib qho teeb meem sib cuam tshuam. Koj tsis tuaj yeem ua kom zoo dua ib theem hauv kev sib cais.
Nws yog niche ua haujlwm. Tab sis thaum koj tau txais nws txoj cai, thiab ib feem koj tau txais los ua haujlwm rau ntau xyoo hauv qhov chaw rau txim uas txhua yam ua tsis tiav, qhov ntawd yog qhov pov thawj. Cov khoom siv tsuas yog qhov chaw pib; cov khawv koob tiag tiag yog nyob rau hauv li cas nws tau ua rau hauv ib feem.
