Thaum koj hnov 'Stellite plug', qhov kev xav tam sim no feem ntau tsuas yog ib qho nyuaj, hnav-tiv taus rau lub valve lossis twj tso kua mis. Qhov ntawd tsis yog qhov yuam kev, tab sis nws yog qhov yooj yim uas tuaj yeem ua rau qhov yuam kev tshwj xeeb. Hauv kev xyaum, nws yog cov qib tshwj xeeb, kev ncaj ncees casting, thiab kev ua haujlwm tom qab uas txhais tau tias nws qhov kev ua tau zoo hauv kev rau txim ib puag ncig. Kuv tau pom ntau qhov tsis ua tiav rov qab los kho txhua yam khoom siv cobalt raws li cov khoom sib hloov tau.
Cov Khoom Nuance Qab Lub Npe
Stellite tsis yog ib qho khoom siv; nws yog tsev neeg ntawm cobalt-chromium alloys. Qhov kev xaiv ntawm, hais, Stellite 6 thiab Stellite 12 rau lub ntsaws tsis yog qhov kev txiav txim siab. Stellite 6 muaj kev hnav zoo heev thiab cavitation tsis kam, uas ua rau peb lub neej ntawd rau ntau daim ntawv thov slurry twj tso kua mis. Txawm li cas los xij, peb ib zaug muaj qhov kub-kub chav cais valve daim ntawv thov qhov twg tus neeg siv tau hais rau Stellite 6 raws li yav dhau los 'kev siv'. Nws underperformed ntawm thermal qaug zog. Hloov mus rau qib siab dua carbon zoo li Stellite 12, uas sib npaug hnav tsis kam nrog cov khoom zoo thermal, daws qhov teeb meem. Zaj lus qhia yog los saib dhau lub npe ntawm lub npe mus rau qhov chaw ua haujlwm tiag tiag - yaig, qhov kub thiab txias, kev tawm tsam corrosion, thiab kev cuam tshuam kev thauj khoom yog txhua yam txiav txim siab.
Qhov no yog qhov chaw ua hauj lwm nrog ib tug foundry uas to taub metallurgy yog tsis-negotiable. Koj tsis tuaj yeem xa daim duab kos thiab cov khoom hu tuaj. Kev sib tham yuav tsum npog tag nrho lub luag haujlwm lub voj voog. Kuv nco qab ib qhov project nrog Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) qhov twg peb tab tom tsim lub pob valve loj rau cov neeg siv khoom petrochemical. Cov spec hu ua npib tsib xee-raws li alloy thawj zaug, tab sis tom qab txiav tawm cov ntaub ntawv kev pabcuam - uas suav nrog cov kab ntawm cov sulfur compounds thiab cyclic thermal shocks - lawv pab pawg engineering tau qhia txog qhov sib txawv ntawm cobalt-raws li alloy lawv muaj kev paub nrog hauv cov chaw zoo sib xws. Cov lus qhia ntawd, los ntawm lawv peb lub xyoo caum hauv kev tsim cov hlau tshwj xeeb, yuav tiv thaiv qhov ua tsis tiav ntxov. Nws yog hom kev sib koom tes tshwj xeeb uas ntxiv tus nqi tiag tiag.
Cov txheej txheem casting nws tus kheej yog qhov tseem ceeb rau cov hlau no. Cov rooj vag tsis zoo lossis riser tsim tuaj yeem ua kom pom qhov porosity ntawm qhov chaw tseem ceeb hauv kev sib khi tseem ceeb lossis hnav qhov chaw. Kuv tau txiav qhib cov plugs tsis lees paub thiab pom cov voids uas tsis pom ntawm qhov chaw. Tias yog vim li cas lub foundry tus txheej txheem tswj, tshwj xeeb tshaj yog rau lub plhaub los yog peev casting ntawm no kim alloys, yog qhov tseem ceeb. Nws tsis yog tsuas yog melting thiab pouring; nws yog hais txog solidification tswj.
Precision Machining: Qhov twg tus tsim raws li kev muaj tiag
As-cam khwb cia Stellite yog ib qho nyuaj nyuaj thiab abrasive rau tshuab. Tau txais qhov kawg tolerances thiab nto tiav ntawm a Stellite ntsaws yog qhov twg ntau qhov project dawm. Koj tsis tuaj yeem tshuab nws zoo li hlau. Cov cuab yeej tsis raug geometry, ceev, lossis pub tus nqi yuav tsuas hlawv cov ntxig lossis, qhov phem dua, ua rau cov micro-cracks hauv txheej txheej, tsim cov ntsiab lus pib ua tsis tiav.
Peb kawm qhov no nyuaj heev thaum ntxov. Ib pawg ntawm cov plugs yuav tsum tau ua kom tiav zoo heev ntawm qhov tapered sealing nto. Peb cov txheej txheem CNC tsis ua rau cov ntaub ntawv nyuaj ua rau kev sib tham thiab qhov chaw subpar. Peb yuav tsum tau sim nrog cov qib tshwj xeeb, ntse-edged carbide thiab kho peb cov nrawm thiab txau. Cov kev daws teeb meem feem ntau cuam tshuam nrog qeeb qeeb, txiav txim siab ntau dua thiab siab-siab txias txias los tswj cov cua sov. Qhov kev tshaj lij machining no yog vim li cas peb feem ntau koom tes nrog cov neeg xa khoom sib koom ua ke xws li QSY, leej twg tuav ob qho tib si casting thiab CNC machining hauv tsev. Nws tshem tawm qhov kev thuam ntawm kev ua si ntawm lub caster thiab tus kws kho tshuab thaum ib feem ua tsis tiav - lawv muaj tag nrho cov txheej txheem los ntawm cov hlau molten mus rau cov khoom tiav. Tshawb xyuas lawv cov peev txheej ntawm https://www.tsingtaocnc.com qhia tau hais tias qhov kev sib koom ua ke ntsug no yog ib feem tseem ceeb ntawm lawv qhov kev muab.
Lwm qhov kev sib tw machining yog tuav lub cam khwb cia. Vim tias qhov kawg geometry feem ntau yog qhov nyuaj, tsim cov khoom sib dhos uas ruaj khov rau qhov tsis sib xws tsis muaj qhov cuam tshuam nws thaum txiav txiav yog ib qho kev kos duab me me. Nws yog ib qho ntawm cov ntsiab lus uas koj tsuas yog txaus siab tom qab scrapping ob peb kim castings.
Failure Analysis: Dab tsi tawg Plugs qhia koj
Kev tshuaj xyuas qhov ua tsis tau zoo yog qhov kev kawm zoo tshaj plaws. Ib lub ntsiab lus rov tshwm sim tsis yog cov khoom siv tsis ua haujlwm, tab sis tsim tsis ua haujlwm. Ib qho piv txwv classic yog qhia tag nrho Stellite ntsaws rau hauv lub kaw lus uas lub rooj sib tw yog cov khoom siv softer. Lub ntsaws yuav ciaj sia zoo nkauj, tab sis nws yuav ua rau lub plab thiab rhuav tshem lub rooj zaum, ua rau muaj dej ntws. Qee zaum, kev daws teeb meem yog Stellite overlay los yog ntxig rau ntawm qhov tseem ceeb sealing av, tsis yog tag nrho cov khoom.
Kuv nco txog ib rooj plaub nyob rau hauv ib lub fais fab nroj tsuag feedwater system. Cov ntsaws ruaj ruaj tau hnav tsis sib xws tab sis tsis kuaj xyuas sai dhau. Lub hauv paus ua rau tsis yog lub ntsaws ruaj ruaj; Nws yog qhov zoo ntawm cov khoom hauv dej tau nkag mus rau hauv cov khoom siv me ntsis softer, tig nws mus rau hauv kev sib tsoo. Kev txhim kho koom nrog rov ntsuam xyuas tag nrho cov khoom khub, tsis yog lub ntsaws. Nws hloov qhov kev sib tham los ntawm kev hloov cov khoom siv yooj yim mus rau qhov kev tshuaj xyuas cov khoom siv qib siab.
Corrosion-pab hnav yog lwm tus neeg tua neeg uas ntsiag to. Stellite alloys muaj kev tiv thaiv corrosion zoo, tab sis lawv tsis yog khawv koob. Hauv kev txo qis acidic ib puag ncig lossis xwm txheej nrog cov tshuaj chlorides ntawm qhov kub siab, cov txheej txheem chromium oxide passive tuaj yeem cuam tshuam. Tus coj tus nqi ces accelerates dramatically. Lub ntsaws uas kav ntau xyoo hauv ib qho kev pabcuam yuav siv sijhawm tsuas yog lub hlis hauv lwm qhov yog tias cov tshuaj tiv thaiv corrosion raug saib xyuas.
Kev sib koom ua ke & Kev Xeem Phaj
Txawm tias zoo kawg nkaus cam khwb cia thiab machined plug tuaj yeem ua tsis tiav ntawm kev teeb tsa. Qhov haum nrog lub rooj zaum yog txhua yam. Peb tam sim no hais kom lapping lub ntsaws thiab lub rooj zaum ua ke raws li qhov sib txuam rau cov ntawv thov tseem ceeb. Qhov no tsis yog ib txwm nyob rau hauv spec, tab sis nws yog pheej yig pov hwm. Cov txheej txheem lapping tsim ib qho zoo meej microscopic foob qauv uas lub tshuab CNC ib leeg feem ntau ua tsis tau.
Kev ntsuas siab yog lwm qhov chaw rau kev muaj tiag. Factory lees txais kev xeem (FAT) nrog dej huv ntawm ambient kub yog pab tau tab sis tsis tag nrho cov neeg sawv cev. Lawv yuav tsis nthuav tawm cov teeb meem ntsig txog thermal expansion qhov sib txawv ntawm lub ntsaws thiab lub valve lub cev. Rau cov kev pabcuam kub kub, peb thawb rau, lossis tsawg kawg simulate, ntsuas kub ua haujlwm. Qhov kev tshem tawm qhov sib txawv suav ntawm chav tsev kub tuaj yeem kaw lossis qhib hauv kev ua haujlwm kub, ua rau kev khi lossis xau.
Cov ntaub ntawv los ntawm qhov chaw tsim khoom yog ib feem ntawm theem no. Daim ntawv pov thawj khoom tsim nyog (MTC) taug qab cov cua sov ntawm cov hlau, nrog rau cov ntaub ntawv soj ntsuam rau kev kuaj xyuas qhov ntev thiab tsis muaj kev puas tsuaj (xws li zas xim rau qhov tsis xws luag), yog qhov yuav tsum tau ua. Nws yog ib feem ntawm passport. Cov neeg muag khoom muaj npe nrov muab qhov no raws li tus qauv. Nws tsim traceability thiab kev ntseeg siab.
Economic & Supply Chain Considerations
Cia peb hais ncaj ncees: cov khoom ntawm cov khoom siv stellite yog kim. Cov ntsiab lus cobalt thiab chromium pom nrog cov khoom lag luam thoob ntiaj teb. Lub instinct yog mus nrhiav tus nqi qis tshaj. Tab sis nrog rau cov khoom no, tag nrho cov nqi ntawm kev ua tswv cuab yog tib qho kev ntsuas uas tseem ceeb. Ib tug pheej yig dua plug uas tsis nyob rau hauv ib nrab lub sij hawm raug nqi ntau dua nyob rau hauv downtime thiab hloov ua hauj lwm tshaj tus nqi rau ib tug kom raug.
Qhov no yog qhov kev sib raug zoo mus sij hawm ntev nrog cov kws tshaj lij kev lag luam them nyiaj. Lawv dhau los ua qhov txuas ntxiv ntawm koj pab pawg engineering. Piv txwv li, thaum thoob ntiaj teb cov khoom lag luam tau nruj ob peb xyoos dhau los, muaj cov channel tsim nrog cov chaw tsim khoom muaj peev xwm zoo li QSY, nrog lawv cov hauv paus tob hauv plhaub molding thiab peev casting ntawm tshwj xeeb alloys, guaranteed continuity. Lawv tuaj yeem tawm tswv yim txog lwm cov khoom siv nrog cov kev ua tau zoo sib xws los ntawm cov khoom lag luam kom ua tiav qhov haujlwm tseem ceeb ntawm lub sijhawm.
Thaum kawg, tsis txhob saib xyuas lub sijhawm ua haujlwm. Qhov tseeb siab ncaj ncees Stellite ntsaws tsis yog ib qho khoom tawm ntawm lub txee. Ntawm cov qauv ua haujlwm, casting, kho cua sov, thiab precision machining, lub sijhawm tiag tiag yog lub lis piam, tsis yog hnub. Rushing ib qho ntawm cov kauj ruam no yog kev cuam tshuam ncaj qha rau qhov zoo. Kev npaj koj cov khoom muag lossis cov sijhawm saib xyuas nyob ib puag ncig qhov tseeb no yog ib feem ntawm kev qhuab qhia kev tshaj lij nrog cov khoom tshwj xeeb no.
