Hauv kev lag luam kev lag luam, cov twj tso kua dej tuaj yeem pom txhua qhov chaw, thiab lawv yog cov khoom siv tseem ceeb los xyuas kom meej tias muaj kev vam meej ntawm ntau yam txheej txheem tsim khoom. Niaj hnub no, cia peb tshawb nrhiav txoj hauv kev ua haujlwm ntawmsilicon carbide slurry twj tso kua misua ke thiab saib seb nws ua lub luag haujlwm tseem ceeb li cas ntawm theem kev lag luam.
1, Txoj cai ua haujlwm yooj yim ntawm cov twj tso kua mis slurry
Lub twj tso kua dej yog lub twj tso kua dej centrifugal. Lub impeller pib tig ntawm qhov ceev ceev zoo li lub tshuab cua uas tig ceev ceev, thiab cov hniav ntawm lub impeller thawb cov kua dej ib puag ncig kom tig ua ke. Cov kua dej raug pov tawm hauv qab lub zog centrifugal thiab sai sai pov los ntawm qhov chaw ntawm lub impeller mus rau ntug sab nraud ntawm lub impeller. Thaum lub sijhawm no, cov kua dej tau txais ntau lub zog kinetic, zoo li tus neeg ncaws pob khiav deb ntawm qhov ceev ceev nrog kev pab ceev ceev.
Thaum cov kua raug pov rau ntug sab nraud ntawm lub impeller, thaj chaw siab qis tau tsim nyob rau hauv nruab nrab ntawm lub impeller, zoo li qhov chaw me me uas muaj qhov siab qis. Thiab cov kua sab nraud nyob rau hauv ib puag ncig siab, zoo li dej ntws mus rau hauv qab. Nyob rau hauv qhov sib txawv ntawm qhov siab, cov kua sab nraud yuav ntws mus rau hauv nruab nrab ntawm lub impeller kom rov ua kom cov kua raug pov tawm.
Tom qab cov kua dej nkag mus rau hauv lub twj tso kua mis, qhov ceev ntawm cov kua dej yuav maj mam txo qis vim yog qhov maj mam nthuav dav ntawm lub twj tso kua mis, zoo li tus dej dav. Hauv cov txheej txheem no, ib feem ntawm lub zog kinetic raug hloov mus ua lub zog siab static, uas zoo li lub tsheb qeeb qeeb, hloov lub zog coj los ntawm qhov ceev mus rau lwm hom zog. Thaum kawg, cov kua dej raug thauj tawm ntawm qhov chaw tso tawm ntawm qhov siab dua, ua tiav ib txoj haujlwm thauj mus los. Tsuav yog lub impeller tseem tig, cov txheej txheem no yuav txuas ntxiv mus, thiab cov kua dej yuav raug nqus thiab zawm tawm tas li.
2, Qhov tshwj xeeb ntawm silicon carbide slurry twj tso kua mis
Shandong Zhongpeng tsom mus rau kev ua cov khoom siv silicon carbide ceramics, thiab lub twj tso kua mis silicon carbide slurry ua los ntawm cov khoom siv no muaj cov txiaj ntsig zoo heev.
1. Kev tiv thaiv zoo heev
Qhov nyuaj ntawm silicon carbide ceramics yog qhov siab heev, nrog Mohs hardness thib ob tsuas yog pob zeb diamond hauv xwm. Nws yog hnav-resistant heev, zoo li hnav ib lub tsho tiv no muaj zog, thiab tuaj yeem tiv taus qhov kev puas tsuaj tas mus li ntawm cov khoom khov hauv slag slurry. Piv nrog rau cov twj tso kua hlau slurry ib txwm muaj, lub neej kev pabcuam ntawm silicon carbide slurry twj tso kua yog ntev heev. Hauv qee qhov xwm txheej kev lag luam uas xav tau kev ua haujlwm ntev thiab kev thauj khoom siab, xws li kev tsuas, metallurgy thiab lwm yam kev lag luam, silicon carbide slurry twj tso kua tuaj yeem ua haujlwm ruaj khov, txo qhov teeb meem thiab tus nqi tshwm sim los ntawm kev hloov khoom siv ntau zaus.
2. Kev tiv thaiv xeb zoo heev
Silicon carbide muaj kev ruaj khov tshuaj lom neeg zoo heev thiab tuaj yeem tiv taus kev xeb mus sij hawm ntev los ntawm cov xov xwm corrosive heev. Hauv kev lag luam xws li tshuaj metallurgy, nws feem ntau tsim nyog thauj ntau yam kua corrosive, thiab cov twj tso kua hlau ib txwm yooj yim puas tsuaj los ntawm kev yaig ntawm cov xov xwm no. Thiab lub twj tso kua silicon carbide slurry zoo li tus tub rog siab tawv uas tsis ntshai xeb, tuaj yeem ua haujlwm ib txwm nyob rau hauv cov chaw ib puag ncig hnyav, ua kom ntseeg tau tias kev tsim khoom txuas ntxiv mus thiab txo cov nqi kho thiab hloov khoom siv.
3. Kev kub siab ua haujlwm tau zoo
Lub twj tso kua silicon carbide slurry tuaj yeem tiv taus qhov kub siab ntawm 1350 ℃, uas ua rau nws ua haujlwm ruaj khov hauv qhov chaw kub siab. Hauv qee qhov kev tsim khoom lag luam uas muaj cov txheej txheem kub siab, xws li lub cub tawg ceramic thiab hlau smelting, cov twj tso kua silicon carbide slurry tuaj yeem ua tau raws li qhov xav tau ua haujlwm tshwj xeeb thiab muab cov kev daws teeb meem txhim khu kev qha rau kev thauj mus los ntawm cov xov xwm kub siab.
3, Cov teb thov ntawm silicon carbide slurry twj tso kua mis
Nrog cov yam ntxwv zoo no, cov twj tso kua silicon carbide slurry tau siv dav hauv ntau qhov chaw xws li kev tsuas thiab metallurgy, ua lub luag haujlwm tseem ceeb hauv kev thauj mus los hauv kev lag luam nrog lawv cov hauv paus ntsiab lus ua haujlwm tshwj xeeb thiab kev ua tau zoo heev. Nrog rau kev nce qib tas mus li thiab kev tsim kho tshiab ntawm thev naus laus zis, peb ntseeg tias cov twj tso kua silicon carbide slurry yuav ua pov thawj lawv cov txiaj ntsig hauv ntau qhov chaw, coj kev ua haujlwm zoo dua thiab txo cov nqi rau kev tsim khoom hauv kev lag luam.
