Nyob rau hauv batch ntau lawm, peb feem ntau ntsib qhov teeb meem no: tej zaum txawv defects tshwm sim vim seemingly tib yam, thiab tej zaum cov tib yam tsis xws luag tshwm sim vim txawv ua. Qhov no qhia tau hais tias qhov tsis xws luag rotor feem ntau yog tshwm sim los ntawm kev sib xyaw ua ke ntawm ntau yam tsis zoo. Tau kawg, yuav tsum muaj qhov laj thawj tseem ceeb. Thaum cov kev hloov pauv, txawm tias tib yam tsis xws luag tshwm sim, qhov tseem ceeb ntawm qhov tsis xws luag yuav hloov.
Piv txwv li, rotor pores feem ntau tshwm sim los ntawm cov pwm tsis zoo los yog pwm tso qhov txhaws. Txawm li cas los xij, qee zaum, txawm tias lub qhov tso pa tawm tsis muaj kev cuam tshuam, cov roj seem tsis tuaj yeem tawm hauv lub sijhawm vim tias lub tshuab nqus dej siab, uas yuav ua rau lub qhov hws hauv lub rotor. Lub sij hawm no, lub ntsiab yog vim li cas rau lub rotor pores tsis yog cov pwm tso tawm teeb meem, tab sis lub pouring ceev teeb meem. Yog li ntawd, thaum soj ntsuam cov teeb meem zoo ntawm cam khwb cia txhuas rotors, nws yog ib qho tsim nyog yuav tsum tau ua ib qho kev ntsuam xyuas raws li qhov chaw thiab cov yam ntxwv ntawm lub rotor tsis xws luag thiab ntau yam kev mob nyob rau hauv thiaj li yuav nrhiav tau ntau yog vim li cas lub ntsiab ntawm cov teeb meem zoo thiab coj cov kev ntsuas kom zoo tiv thaiv qhov tshwm sim ntawm cam khwb cia txhuas rotor defects.
Ua ke nrog cov tsis xws luag ntawm nyias rotor tuav, tawg tuav, shrinkage qhov, kab nrib pleb, thiab lwm yam uas tau hais los saum no, Ms. San yuav tsom mus rau qhov txias kaw thiab rotor conformity teeb meem ntawm cam khwb cia txhuas rotors nrog Baowei hnub no. Qhov tsis ua tiav ntawm molten aluminium kom puv lub pwm kab noj hniav yog hu ua "tsis tiav pouring". Qhov chaw uas lub rotor tsis nchuav los yog cov npoo tsis meej yog cov kiv cua thiab cov kab sib npaug. Txias kaw yog hais txog cov pob qij txha los yog qhov chaw uas cov molten aluminium tsis ua tiav. Cov ntug kev sib tshuam yog du thiab pom tseeb tshaj plaws ntawm cov kiv cua.
Ua rau lub qhov txias kaw tsis xws luag
● Qhov kub ntawm cov molten aluminium yog tsawg dhau thaum lub sij hawm nchuav; lub pouring ceev yog qeeb heev los yog muaj ib tug txaus cuam tshuam phenomenon. ● Qhov kub ntawm cov pwm thiab cov tub ntxhais yog tsawg. ● Aluminium to los yog tsis txaus molten aluminium. ● Kev sib hloov ceev tsis txaus. ● Qhov seem ntawm lub rooj vag sab hauv yog me me dhau los yog cov pwm tsis tau vented smoothly. ● Sib cais los ntawm oxide nplai lossis lwm yam suav nrog. Txias kaw qhov tsis xws luag tswj ntsuas ● Qhov kub ntawm lub molten aluminium yuav tsum tau raws li tus nqi teev, thiab lub pouring ceev yuav tsum raug tswj kom raug. Nws yuav tsum tau nchuav rau hauv ib lub sijhawm. ● Tsim kom muaj qhov kub thiab txias ntawm cov pwm, tshwj xeeb tshaj yog cov hauv paus hniav kub (rau cov khoom siv uas tsis tshua muaj siab, ua kom cov pwm qis dua ● Tshem tawm aluminium to. Thaum pouring aluminium, siv 10 ~ 20% ntau tshaj qhov tseeb rotor. ● Tswj qhov ceev. Yog tias qhov ceev yog siab dhau ntawm qhov pib ntawm cov dej ntws,
nws yuav ua rau av voids. (5) Khaws cov pa tawm kom tsis txhob muaj kev cuam tshuam thiab lub hnub nchuav tuaj yeem ua kom haum. ● Khaws cov pwm thiab cov tub ntxhais kom huv si thiab tsis muaj khib nyiab. Ua tib zoo saib xyuas qhov stimulation thiab ntxuav ntawm cov dej sib thooj. Rotor tsis kam tshaj qhov kam rau ua (1) Kev soj ntsuam ntawm cov laj thawj rau lub rotor tsis kam tshaj qhov kam rau ua ● Cov tub ntxhais yog ntev dhau lawm, los yog qhov nqes nqes siab tshaj qhov tso cai rau tus nqi, uas ua rau lub tawb bar kuj nce ntxiv. ● Lub rotor yog misaligned thiab serrated, uas txo qhov zoo ntawm cov txhuas bar. ● Aluminium dej Kev tu los yog slag tu tsis zoo, thiab muaj ntau tus pinholes thiab impurities. ●Qhov zoo ntawm rotor aluminium casting yog qhov tsis zoo, nrog rau qhov tsis xws luag xws li qhov pores, shrinkage kab noj hniav, shrinkage, slag inclusions, tawg los yog txias kaw. ● Cov qib tsis raug ntawm aluminium ingot yog siv los yog qhov tsis zoo, thiab cov conductivity tsawg. (2) Lub rotor tsis kam yog me me, uas feem ntau tshwm sim hauv aluminium alloy rotors. Tej zaum nws yuav yog cov khoom siv high-purity aluminium ingots siv tsis raug, los yog qhov nqes nqes qis dua tus nqi, uas txo cov tawb bar tsis kam. Tswj kev ntsuas rau rotor tsis kam tiv thaiv cov teeb meem ntawm kev kam rau siab ● Ua ntej nias thiab nchuav cov tub ntxhais, ua tib zoo xyuas cov tub ntxhais qhov ntev thiab txoj kab nqes, uas yuav tsum tau ua raws li qhov yuav tsum tau ua ntawm daim duab kos. ● Ua haujlwm zoo ntawm kev ntxuav thiab tshem tawm slag ntawm cov kua txhuas. ● Tshem tawm cov rotor qhov tsis xws luag xws li cov pores thiab shrinkage kab noj hniav. ● Siv cov khoom siv txhuas ntawm cov qib teev tseg.
