Yuav Ua Li Cas Xaiv Lub Dav Hlau Suction Kub Dredger? Cov xwm txheej hauv av tseem ceeb tshaj qhov loj ntawm Dredger

Thaum cov neeg siv khoom pib nrhiav cov cuab yeej siv rau qhov project underwater kub mining, ib qho ntawm thawj yam uas lawv feem ntau nug txog yog lub dredger.

"Koj puas muaj lub dav hlau suction kub dredger?"

"Yuav ua li cas tob nws dredge?"

"Nws muaj peev xwm ua tau ntau npaum li cas ib hnub?"

"Lub tshuab slurry loj npaum li cas?"

"Puas yog tag nrho cov kub dredging system nqi?"

Cov no yog tag nrho cov lus nug tsim nyog. Txawm li cas los xij, thaum peb pib ua haujlwm ntawm cov khoom siv tiag tiag, ntau tus neeg siv khoom paub tias cov kev qhia tshwj xeeb no ib leeg tsis tuaj yeem txiav txim siab seb lub dredger puas haum rau lawv thaj chaw mining.

Peb tau ua hauj lwm nrog cov neeg muas zaub uas pib xav tsim ib tug dredger ncaj qha los ntawm cov khoom siv nyob rau hauv lwm qhov chaw kub mining. Tom qab sib tham txog qhov tseeb ntawm qhov chaw, txawm li cas los xij, peb pom tias ob thaj chaw mining txawv kiag li.

Qee lub pas dej muaj feem ntau ntawm cov xuab zeb xoob. Lwm tus muaj cov pob zeb loj heev. Ib txhia muaj av nplaum cov ntsiab lus siab, thaum nyob rau lwm qhov chaw, cov kub - txheej bearing nyob tob hauv qab tus dej.

Nyob rau hauv cov xwm txheej no, lub hull loj, cov yeeb nkab nqus, lub twj tso kua mis slurry, thiab cov khoom siv hauv qab thiab cov khoom siv rov qab tsis tuaj yeem luam tawm los ntawm lwm qhov project.

Tias yog vim li cas, thaum tsim lub dav hlau suction kub dredger, thawj lo lus nug yuav tsum tsis txhob yog "Lub dredger yuav loj npaum li cas?"

Cov lus nug tseem ceeb tshaj yog:

Yam khoom twg yuav tsum tau rov qab, thiab ntau npaum li cas cov ntaub ntawv yuav tsum tau ua raws li qhov tseeb ntawm qhov chaw?

Lub Dav Hlau Suction Kub Dredger tsuas yog lub hauv ntej kawg ntawm qhov system

Lub hauv paus ntsiab lus ua haujlwm ntawm lub dav hlau suction kub dredger yog qhov ncaj.

Lub siab - lub twj tso kua dej siab xa dej mus rau qhov chaw ua haujlwm hauv qab dej, siv cov dej ntws los tshem cov xuab zeb thiab pob zeb. Lub twj tso kua mis slurry ces nqus cov dej, xuab zeb, gravel, thiab cov ntxhia muaj txiaj ntsig rau hauv cov raj xa dej thiab xa mus rau kev tshuaj ntsuam, ntxuav, thiab cov khoom siv rov qab.

Rau ib txoj haujlwm dredging ib txwm ua, cov txheej txheem yuav tsum tau xaus tom qab cov khoom siv dredged tau raug thauj mus rau qhov chaw tsim.

Kub mining txawv.

Cov khoom siv rov qab los ntawm lub dredger tsuas yog cov khoom noj nyoos xwb. Nws tseem yuav tsum tau mus dhau ntau theem ua.

Ib tug txheej txheem yuav zoo li no:

Underwater mineralized xuab zeb → Suction → Slurry thauj → Kev tshuaj ntsuam → Ntxuav → Lub ntiajteb txawj nqus sib cais → Concentrate rov qab

Vim li no, thaum peb tsim kub dredging tshuab, peb tsis tsom tsuas yog lub peev xwm slurry twj tso kua mis.

Piv txwv li, lub dredger tej zaum yuav muaj peev xwm rov qab tau cov khoom ntim loj hauv ib teev, tab sis yog tias lub trommel tsis tuaj yeem ua cov khoom xa tuaj sai txaus, qhov kev tshuaj ntsuam yuav dhau los ua lub hauv paus.

Qhov no yog vim li cas thaum tus neeg siv khoom nug peb kom yooj yim "nruab lub twj tso kua mis loj dua," peb kuj yuav tsum nkag siab tias qhov kev tshuaj ntsuam xyuas thiab kev rov ua haujlwm yuav raug teeb tsa li cas.

Ib qho teeb meem feem ntau pom tsuas yog tom qab qhov project pib

Cov neeg siv khoom feem ntau nkag siab txog qhov tob tob thiab kev ua haujlwm tau yooj yim heev. Dab tsi yog qee zaum overlooked yog qhov xwm ntawm cov khoom nws tus kheej.

Xav txog ob txoj haujlwm dej kub mining.

Thawj qhov project muaj cov xuab zeb xoob xoob nrog cov pob zeb tsawg, thiab cov khoom kub -cov khoom tuaj yeem loosened kuj yooj yim los ntawm dej.

Qhov thib ob txoj haujlwm muaj qhov tob dej zoo sib xws, tab sis cov xuab zeb txheej muaj cov pob zeb ntau dua thiab av nplaum.

Kev siv tib lub tshuab nqus tsev rau ob txoj haujlwm yuav ua rau muaj txiaj ntsig sib txawv.

Thaum muaj ib qho tseem ceeb ntawm cov pob zeb, tus tsim yuav tsum xav txog ntau tshaj li cov twj tso kua mis slurry xwb. Lub taub hau nqus, nqus cov yeeb nkab, cov khoom siv tshuaj ntsuam xyuas, thiab lub peev xwm ntawm cov kav dej kom dhau cov khoom siv kuj tseem ceeb heev.

Thaum cov av nplaum cov ntsiab lus siab, qhov teeb meem tuaj yeem sib txawv. Cov khoom siv tuaj yeem tsim cov pob me me, ua rau lub sijhawm ntxuav tseem ceeb dua li tsuas yog ua kom lub ntim nqus.

Qhov no yog vim li cas peb feem ntau hais kom cov neeg siv khoom muab cov duab thiab yeeb yaj kiab ntawm qhov chaw mining.

Qee zaum, cov vis dis aus luv luv nrog lub xov tooj ntawm tes tuaj yeem qhia tus kws tshaj lij txog qhov tseeb ntawm cov dej hauv qab dua li cov npe ntawm cov khoom siv tshwj xeeb.

Lub twj tso kua mis loj dua tsis tuaj yeem txhais tau tias kub dua

Qhov no yog lwm qhov kev nkag siab tsis zoo thaum yuav cov khoom siv kub dredging.

Lub twj tso kua mis slurry loj tuaj yeem muab kev thauj mus los ntau dua thaum ua kom zoo nrog cov kav dej, lub cav, thiab kev ua haujlwm.

Tab sis nws tsis cia li txhais tau tias kub ntau lawm.

Tus nqi ntawm cov kub rov qab thaum kawg yog nyob ntawm tus yam ntxwv ntawm qhov tso nyiaj.

Yog tias cov ntsiab lus kub ntawm qhov tso nyiaj tsawg, kev ua haujlwm ntau ntawm cov khoom txhua hnub tseem tuaj yeem ua rau cov khoom kub tsawg.

Ntawm qhov tod tes, txawm tias qhov tso nyiaj muaj cov ntsiab lus kub zoo, kev kuaj xyuas tsis raug lossis lub ntiajteb txawj nqus rov qab tuaj yeem txo qhov kev ua haujlwm rov qab kawg.

Vim li no, peb ib txwm saib ntau yam ua ke:

Mining peev, slurry tsheb thauj mus los muaj peev xwm, tshuaj ntsuam xyuas, muaj peev xwm ntxuav, thiab kub rov ua haujlwm.

Yog tias cov khoom no tsis zoo sib xws, tsuas yog ib qho parameter tuaj yeem txhim kho lub peev xwm ntawm cov khoom tiav.
