Dab tsi yog slurry twj tso kua mis? Txhawm rau muab nws yooj yim:
Cov twj tso kua mis zoo tib yam tso dej huv, thaum cov twj slurry twj tso kua mis "dej qias neeg" - thiab nws yog hom sib xyaw nrog xuab zeb, pob zeb, thiab slag nyob rau hauv siab - concentration slurry.
Koj tuaj yeem xav tias nws yog "super nqus tsev vacuum", tshwj tsis yog tias nws tsis nqus plua plav; xwb, nws nqus cov khoom sib tov - kua. Hlau ore slurries los ntawm mines, thee slurry dej los ntawm thee ntxuav cov nroj tsuag, thiab slurry los ntawm dej dredging ... tag nrho cov "cov hauj lwm nyuaj" yuav tsum tau cov kev pab cuam ntawm slurry twj.
Core Technology 1: Flow Cheebtsam - "Key" rau lub twj tso kua mis
Lub tshuab tseem ceeb ntawm slurry twj tso kua mis nyob rau hauv nws "ntws Cheebtsam" - uas yog, tag nrho cov seem los ntawm cov slurry ntws: impeller, casing, pem hauv ntej guard phaj, rear guard phaj.
Cov Cheebtsam no tau "polished" tas li los ntawm siab -ceev ntws ntxhia xuab zeb, ib yam li txau xuab zeb nrog lub siab - rab phom dej los txhuam cov phaj hlau. Tus hnav tus nqi yog ceev heev. Yog li ntawd, cov khoom ntawm cov khoom no txiav txim siab lub neej ntawm lub twj tso kua mis.
Lub tshuab tseem ceeb tam sim no yog siab -chromium alloy casting. Hauv cov ntsiab lus yooj yim, chromium cov ntsiab lus tau ntxiv rau cov hlau cam khwb cia ua cov carbides nyuaj, nrog hardness piv rau ceramics. Qee cov khoom siab - kawg txawm siv cov roj hmab hauv ob sab phlu lossis ceramic txheej, uas yog tshwj xeeb tshaj yog tiv thaiv acidic slurry.
Cov khoom ntws ntawm cov twj zoo tib yam zoo li "khoom qab zib", thaum cov twj slurry zoo li "grilled hlau phaj" - lawv tsoo taub hau- rau, thiab leej twg ntshai leej twg?
Core Technology 2: Sealing System - Tsis txhob cia lub Slurry "Leak"
Dab tsi yog qhov teeb meem nyuaj tshaj plaws rau cov twj slurry? Cov dej ntws tawm.
Thaum lub siab -siab slurry leaks los ntawm cov ncej foob, nws tsis tsuas yog ua phem rau ib puag ncig, tab sis kuj sai sai hnav lub tes tsho ncej. Yuav kom daws tau qhov teeb meem no, engineers tuaj nrog ob txoj kev daws teeb meem:
Packing Foob: Siv cov ntim mos ntim rau hauv cov roj nplua nyeem kom "sau" thaj tsam ntawm lub tog raj kheej, tso siab rau me ntsis kom txias thiab lubricate. Qhov kom zoo dua yog tus nqi qis thiab kev saib xyuas yooj yim, tab sis qhov tsis zoo yog me ntsis dripping.
Mechanical Seal: Ob lub ntsej muag kawg raug nias ua ke thiab tig ntawm kev kub ceev kom tsim ib qho yuav luag xoom- leakage foob. Qhov no yog qhov kev daws teeb meem zoo tshaj plaws rau cov tshuaj lom, siab -kub, thiab siab -concentration slurry.
Niaj hnub no, ntau lub twj tso kua mis siab kuj ntxiv lub impeller lub zog thib ob lub foob - siv lub zog centrifugal los tsim "qhov tsis zoo siab" ntawm lub foob foob ncaj qha rau "thaiv" slurry. Qhov kev sib xyaw ua ke ntawm kev ntsuas no txo qis qhov xau mus rau qhov tsawg kawg nkaus.
Koj puas paub? Cov twj slurry kuj muaj "cov kab mob ua haujlwm".
Cov teeb meem feem ntau nrog cov twj slurry yog cavitation thiab hnav.
Cavitation tshwm sim vim hais tias lub inlet siab tsawg dhau lawm, thiab cov slurry "boils" nyob rau hauv lub twj tso kua mis, tsim npuas uas tawg thiab cuam tshuam rau cov hlau nto, ua suab nrov xws li teeb tawm firecrackers nyob rau hauv lub twj tso kua mis. Ntev- lub sij hawm cavitation tuaj yeem ua rau lub impeller los ua pockmarked zoo li honeycomb.
Hnav yog qhov pom tseeb dua - cov khoom nyuaj hauv cov slurry zoo li suav tsis txheeb cov riam me me, tas li khawb cov khoom ntws. Yog li ntawd, tsis tu ncua hloov lub tes tsho tiv thaiv thiab impeller yog ib qho yuav tsum tau rau cov neeg siv cov twj slurry.
Los ntawm cov mines mus rau kev tiv thaiv ib puag ncig, nws tuaj yeem pom nyob txhua qhov chaw.
Tej zaum koj yuav tsis tau pom lub twj tso kua mis slurry, tab sis nws pab koj txhua hnub:
Coal mines: Thauj thee sludge dej tsim los ntawm thee ntxuav mus rau hauv lub tank sedimentation
Fais fab nroj tsuag: thauj limestone slurry tom qab desulfurization
Kev tswj tus dej: tso cov av thiab xa rov qab mus rau tus dej kom pom tseeb
Steel mills: thauj hlau oxide slimes thiab moj tej tawg rauv slurry
Yog tias tsis muaj cov twj slurry, "khoom khib nyiab" hauv cov kev lag luam no tsuas yog tsis tuaj yeem ua haujlwm. Hu nws "lub raum" ntawm kev lag luam ncig tsis yog ib qho exaggeration txhua.
