Hauv ntiaj teb ntawm kev ntsuas kev lag luam, cov phaj granite feem ntau nyiag lub teeb pom kev zoo rau lawv qhov tiaj tiaj thiab kev ruaj khov thermal hauv cov chaw tswj hwm. Txawm li cas los xij, thaum peb tawm ntawm qhov chaw zoo nkauj ntawm chav kuaj xyuas zoo thiab mus rau hauv pem teb rugged, dynamic ntawm lub Hoobkas tsim khoom hnyav, qhov yuav tsum tau ua rau cov cuab yeej siv precision hloov pauv ntau heev. Qhov no yog qhov twg cov phaj hlau cam khwb cia (feem ntau hu ua kev tshuaj xyuas hlau cam khwb cia lossis cov platforms xeem) ua pov thawj lawv tus nqi. Txawm hais tias lawv yuav tsis ib txwm phim cov ultra-fine tolerances ntawm chav kuaj granite, lawv qhov kev sib xyaw ua ke ntawm kev tawv, kev co damping, thiab lub peev xwm thauj khoom ua rau lawv xaiv zoo dua rau kev tshuaj xyuas kev lag luam hnyav.
Kev Tiv Thaiv Kev Cob Qhia Tsis Sib Xws rau Cov Chaw Ib Puag Ncig Dynamic
Ib qho ntawm cov laj thawj tseem ceeb tshaj plaws los xaiv lub phaj hlau cam khwb cia hauv kev lag luam yog nws lub peev xwm ua kom lub zog co zoo heev. Hauv lub chaw ua haujlwm uas muaj neeg coob coob uas muaj cov forklifts, stamping presses, thiab CNC tshuab, kev co ib puag ncig yog qhov tseeb tas li uas tuaj yeem ua rau muaj kev puas tsuaj rau kev ntsuas rhiab heev.
Cov hlau cam khwb cia, tshwj xeeb yog cov hlau grey cam khwb cia muaj zog heev (feem ntau yog qib HT200 txog HT300), muaj cov qauv microstructure tshwj xeeb uas muaj cov flake graphite. Cov qauv sab hauv no muab cov hlau cam khwb cia ib qho coefficient damping uas yog 6 txog 10 npaug ntau dua li cov hlau. Yeej, cov khoom siv ua haujlwm ua lub zog nqus dej ntuj, sai sai dissipate lub zog los ntawm kev co sab nraud lossis kev cuam tshuam sab hauv. Rau cov neeg soj ntsuam ntsuas cov khoom loj, hnyav lossis siv cov khoom siv kuaj dynamic, lub phaj hlau cam khwb cia muab lub hauv paus "ntsiag to," ruaj khov uas ua kom ntseeg tau tias cov ntawv nyeem ntsuas tseem raug txawm tias nyob hauv ib puag ncig ua haujlwm nrov nrov.
Muaj Peev Xwm Thauj Khoom Zoo Tshaj Plaws thiab Kev Ruaj Ntseg
Kev tshuaj xyuas hnyav feem ntau yuav tsum muab cov khoom ua haujlwm loj loj - xws li cov thaiv cav, cov tsev turbine, lossis cov thav duab vuam loj - tso rau ntawm qhov chaw piv txwv. Qhov no yog qhov uas cov khoom siv kho tshuab ntawm cov hlau cam khwb cia ci ntsa iab tiag tiag.
Cov phaj hlau cam khwb cia yog tsim los rau lub zog loj heev. Nrog lub zog compressive ncav cuag 200-300 MPa thiab qhov nyuaj ntawm qhov chaw feem ntau ntawm HB170 thiab HB240, lawv tuaj yeem yooj yim txhawb nqa cov khoom thauj los ntawm ntau tons mus rau ntau kaum tons yam tsis muaj kev hloov pauv. Cov chaw tsim khoom feem ntau txhim kho lub peev xwm no los ntawm kev tsim cov phaj nrog lub thawv-hom qauv txhawb nqa los ntawm lub grid ntawm cov tav sab hauv (feem ntau optimized siv finite element analysis). Qhov kev tsim no ua rau muaj kev ruaj khov siab tshaj plaws thaum tswj hwm qhov hnyav, ua kom qhov chaw tseem tiaj tus txawm tias nyob rau hauv qhov siab heev, concentrated siab.
Tsis tas li ntawd xwb, tsis zoo li granite, uas tuaj yeem tawg yooj yim thiab yooj yim tawg yog tias raug ntaus los ntawm cov hlau hnyav, cov hlau cam khwb cia yog cov khoom ruaj khov heev thiab tiv taus kev cuam tshuam. Nws tuaj yeem tiv taus qhov tsis zam, poob, thiab kev co ntawm pem teb tsim khoom yam tsis muaj kev puas tsuaj loj heev. Tsis tas li ntawd xwb, cov hlau cam khwb cia yog cov khoom siv tiv taus kev hnav. Cov txheej txheem khawb tes siv los ua kom tiav cov hlau cam khwb cia siab tsim cov hnab me me ntawm qhov chaw uas tuaj yeem tuav cov roj me me, muab cov roj nplua nyeem ntuj thiab ua kom lub phaj tswj tau nws qhov tseeb dhau ntau xyoo ntawm kev swb cov khoom hnyav hla nws.
Kev hloov pauv ntau yam hauv kev teeb tsa thiab kev sib dhos
Hauv kev lag luam hnyav, kev tshuaj xyuas tsis tshua yog hais txog kev muab ib feem tso rau ntawm lub rooj tiaj tiaj xwb. Nws feem ntau cuam tshuam nrog kev teeb tsa nyuaj, kev clamping, thiab kev sib dhos ua ke. Cov phaj hlau cam khwb cia muaj qib kev ua haujlwm ntau yam uas cov pob zeb lossis cov phaj hlau khov kho tsis tuaj yeem sib piv.
Qhov saum npoo ntawm lub phaj hlau cam khwb cia tuaj yeem ua tau yooj yim kom suav nrog T-slots, U-slots, lossis cov qhov threaded. Cov yam ntxwv no tso cai rau cov neeg tshuaj xyuas thiab cov kws kho sib dhos siv T-bolts thiab clamps los khi cov khoom ua haujlwm, cov khoom siv, lossis txawm tias cov khoom siv kuaj ncaj qha rau lub phaj. Lub peev xwm "datum ntxiv rau kev kho" no muaj txiaj ntsig zoo. Nws tiv thaiv cov khoom hnyav lossis cov khoom tsis zoo los ntawm kev hloov pauv thaum lub sijhawm ntsuas, txhim kho kev nyab xeeb thiab kev ua haujlwm zoo heev. Txawm hais tias nws yog rau kev sib dhos lub gearbox loj, teeb tsa lub cav rau kev sim kev ua tau zoo, lossis ua haujlwm ua lub cuab yeej vuam ruaj khov, lub phaj hlau cam khwb cia hloov pauv los ntawm cov cuab yeej ntsuas yooj yim mus rau hauv lub rooj ua haujlwm ntau yam kev lag luam.
Kev Ruaj Ntseg Mus Ntev Los Ntawm Kev Tsim Khoom Siv Zoo
Ib qho kev nkag siab yuam kev feem ntau yog tias cov hlau cam khwb cia yooj yim khoov. Txawm li cas los xij, cov hlau cam khwb cia zoo hauv kev lag luam raug tsim cov txheej txheem tsim khoom nruj heev uas tsim tshwj xeeb los tshem tawm qhov kev pheej hmoo no.
Yuav kom ntseeg tau tias cov khoom siv hlau yuav ruaj khov mus ntev, cov chaw tsim khoom uas muaj npe nrov yuav tsum tau kho cov hlau kom zoo. Feem ntau, kev laus ntawm cov hlau no yuav tsum tau ua ke nrog kev laus dag (annealing ntawm qhov kub ntawm 600°C thiab 700°C) thiab kev laus ntuj (cia cov hlau no nyob sab nraum zoov li 2 txog 3 xyoos). Cov txheej txheem no pab txo tau ntau tshaj 90% ntawm cov kev ntxhov siab sab hauv uas tshwm sim thaum lub sijhawm ua cov hlau. Yog li ntawd, cov hlau uas tau kho kom zoo yuav tiv taus kev hloov pauv mus tas li, thiab tseem ua kom nws ruaj khov tau ntau xyoo.
Lwm qhov zoo ntawm kev lag luam ntawm cov hlau cam khwb cia yog nws txoj kev kho tau. Yog tias lub phaj granite puas lawm, nws feem ntau nyuaj lossis tsis tuaj yeem kho tau. Qhov sib piv, qhov chaw hlau cam khwb cia uas hnav lossis puas me ntsis tuaj yeem rov qab mus rau nws qhov tseeb qub los ntawm cov txheej txheem hu ua rov khawb dua. Lub peev xwm no los kho qhov chaw ua haujlwm ntev dua cov khoom siv, ua rau nws yog kev nqis peev zoo rau txhua qhov chaw lag luam.
Xaus Lus: Sib phim cov cuab yeej rau txoj haujlwm
Kev xaiv lub phaj nto zoo yog hais txog kev sib phim cov khoom siv rau koj qhov chaw ua haujlwm tshwj xeeb. Yog tias koj txoj haujlwm tsuas yog nyob rau hauv chav kuaj ntsuas kub uas xav tau qhov tseeb ntawm sub-micron rau cov khoom me me, granite tseem yog qhov kev xaiv zoo heev.
Txawm li cas los xij, thaum koj cov haujlwm tshuaj xyuas tsiv mus rau hauv pem teb kev lag luam hnyav - qhov twg kev co tas li, cov khoom ua haujlwm hnyav ntau heev, kev cuam tshuam yuav tshwm sim, thiab kev sib txuas nyuaj - cov phaj hlau cam khwb cia yog cov yeej tsis muaj kev sib cav. Lawv lub peev xwm thauj khoom ruaj khov, kev co zoo heev, kev teeb tsa T-slot ntau yam, thiab kev ua haujlwm ntev ua rau lawv zoo tagnrho "lub xub pwg hlau" rau kev lag luam hnyav. Los ntawm kev nqis peev rau hauv lub platform tshuaj xyuas hlau cam khwb cia zoo, koj tau ruaj ntseg lub hauv paus ruaj khov, txhim khu kev qha, thiab kav ntev rau koj cov teeb meem tsim khoom thiab kev sim uas xav tau tshaj plaws.
