Txog thaum Lub Ob Hlis 2020, lub chaw tso roj hauv lub chaw nres nkoj Brazilian tau siv ob lub tshuab centrifugal los thauj cov roj hnyav los ntawm lub tank cia rau lub tsheb thauj khoom lossis nkoj. Qhov no yuav tsum tau txhaj cov roj diesel kom txo cov viscosity siab ntawm qhov nruab nrab, uas yog kim. Cov tswv tsev khwv tau tsawg kawg yog $2,000 toj ib hnub. Tsis tas li ntawd, cov twj centrifugal feem ntau ua tsis tiav vim cavitation puas. Tus tswv txiav txim siab thawj zaug hloov ib qho ntawm ob lub twj tso kua mis centrifugal nrog NOTOS® multiscrew twj tso kua mis los ntawm NETZSCH. Ua tsaug rau nws lub peev xwm nqus tau zoo heev, qhov kev xaiv 4NS plaub-ntsia taub twj tso kua mis kuj tseem tsim nyog rau cov viscosity tshaj tawm txog 200,000 cSt, xa cov nqi ntws mus txog 3000 m3 / h. Tom qab kev ua haujlwm, nws tau pom tseeb tias lub twj tso kua mis ntau tuaj yeem ua haujlwm yam tsis muaj cavitation txawm tias muaj cov nqi ntws ntau dua piv rau lwm cov twj centrifugal. Lwm qhov zoo dua yog tias nws tsis tas yuav ntxiv cov roj diesel ntau ntxiv lawm. Raws li qhov kev paub zoo no, thaum Lub Ob Hlis 2020 tus neeg siv khoom kuj tau txiav txim siab hloov lub twj tso kua mis thib ob nrog NOTOS ® . Tsis tas li ntawd, nws yog qhov tseeb tias kev siv hluav taws xob tuaj yeem txo qis.
"Cov twj no yog siv los thauj cov roj hnyav los ntawm cov chaw ua liaj ua teb rau cov tsheb thauj khoom lossis cov nkoj hauv cov chaw nres nkoj ntawm sab qaum teb-sab hnub tuaj Brazil, feem ntau thaum lub caij ntuj qhuav," piav qhia Vitor Assmann, Tus Thawj Saib Xyuas Muag Khoom Loj ntawm NETZSCH Brazil. "Qhov no yog vim lub teb chaws cov chaw tsim hluav taws xob hluav taws xob tsim hluav taws xob tsawg dua nyob rau lub sijhawm no, uas ua rau qhov kev thov rau cov roj hnyav ntxiv. Txog rau Lub Ob Hlis 2020, qhov kev hloov pauv no tau ua tiav siv ob lub twj tso kua mis centrifugal, tab sis lub twj centrifugal no tau tawm tsam nrog cov viscosity siab." ib puag ncig. "Cov twj centrifugal ib txwm muaj peev xwm nqus tau tsis zoo, uas txhais tau hais tias qee cov roj tseem nyob hauv lub tank thiab siv tsis tau," piav qhia Vitor Assmann. "Tsis tas li ntawd, kev siv tshuab tsis raug tuaj yeem ua rau cavitation, uas yuav ua rau lub twj tso kua mis tsis ua haujlwm rau lub sijhawm ntev."
Ob lub twj tso kua mis centrifugal ntawm Brazilian tank ua liaj ua teb kuj raug kev txom nyem los ntawm cavitation. Vim yog lub siab viscosity, NPSHa tus nqi ntawm lub kaw lus yog tsawg, tshwj xeeb tshaj yog thaum hmo ntuj, uas ua rau qhov yuav tsum tau ntxiv cov roj diesel kim rau cov roj hnyav kom txo cov viscosity. "Txog 3,000 litres yuav tsum tau ntxiv txhua hnub, uas raug nqi tsawg kawg yog $ 2,000 ib hnub," Asman hais ntxiv. Txhawm rau txhim kho cov txheej txheem kev ntseeg tau thiab ua haujlwm tau zoo thiab txo cov nqi hluav taws xob, tus tswv txiav txim siab hloov ib qho ntawm ob lub twj tso kua mis centrifugal nrog NOTOS ® multiscrew twj tso kua mis los ntawm NETZSCH thiab sib piv cov kev ua tau zoo ntawm ob chav.
NOTOS ® ntau yam feem ntau suav nrog ntau lub twj tso kua mis nrog ob (2NS), peb (3NS) lossis plaub (4NS) cov ntsia hlau, uas tuaj yeem siv tau yooj yim los tswj cov viscosities sib txawv thiab txawm tias cov nqi ntws siab. Ib lub tuam txhab roj hauv Brazil xav tau lub twj tso kua mis uas muaj peev xwm siv tau txog 200 m3 / h ntawm cov roj hnyav ntawm qhov siab ntawm 18 bar, qhov kub ntawm 10-50 ° C thiab viscosity txog li 9000 cSt. Tus tswv lub tank ua liaj ua teb xaiv rau 4NS ntxaib ntsia hlau twj tso kua mis, uas muaj peev xwm txog li 3000 m3 / h thiab tsim nyog rau cov xov xwm viscous siab txog 200,000 cSt.
Lub twj tso kua mis yog qhov txhim khu kev qha, tuaj yeem tiv taus kev khiav qhuav thiab tuaj yeem tsim los ntawm cov ntaub ntawv tshwj xeeb xaiv rau daim ntawv thov. Cov thev naus laus zis niaj hnub no tso cai rau kev ua siab ntev ntawm cov khoom siv hluav taws xob thiab zoo li qub, yog li txo qhov xav tau rov qab. Nyob rau hauv ua ke nrog cov ntws-optimized twj chamber zoo, high efficiency yog tiav.
Txawm li cas los xij, ntxiv rau kev ua tau zoo, qhov hloov pauv ntawm lub twj tso kua mis nyob rau hauv cov nqe lus ntawm viscosity ntawm lub twj nruab nrab yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov tswv ntawm Brazilian tank ua liaj ua teb: "Thaum kev khiav hauj lwm ntau ntawm cov twj centrifugal yog nqaim thiab raws li cov viscosity nce, lawv cov efficiency txo qis heev. NOTOS ® multi-ntsia hlau twj tso kua mis ua hauj lwm zoo heev nyob rau hauv tag nrho Senior. "Lub tswv yim twj tso kua mis no yog tsim los ntawm kev sib cuam tshuam ntawm auger thiab vaj tse. Nws tsim lub chamber thauj khoom uas qhov nruab nrab txav tsis tu ncua los ntawm sab nkag mus rau sab tawm hauv qhov siab ruaj khov - yuav luag tsis hais qhov sib xws lossis viscosity ntawm qhov nruab nrab." Tus nqi ntws yog cuam tshuam los ntawm lub twj tso kua mis ceev, txoj kab uas hla thiab lub suab ntawm lub auger. Yog li ntawd, nws yog ncaj qha proportional rau qhov ceev thiab yuav smoothly kho los ntawm nws.
Cov twj no tuaj yeem hloov kho rau daim ntawv thov tam sim no kom ua tiav qhov kev ua tau zoo. Qhov kev txhawj xeeb no feem ntau yog qhov ntev ntawm lub twj tso kua mis thiab nws qhov kam rau ua, nrog rau cov khoom siv ntxiv. Piv txwv li, overpressure li qub, ntau lub tshuab sealing thiab cov cuab yeej saib xyuas siv qhov ntsuas kub thiab vibration sensors tuaj yeem siv. "Rau daim ntawv thov Brazilian, cov viscosity ntawm cov xov xwm ua ke nrog kev ceev ntawm lub twj tso kua mis yuav tsum tau muab ob npaug rau foob nrog lub kaw lus sab nraud," piav qhia Vitor Assmann. Raws li tus neeg thov kev thov, tus qauv tsim ua raws li API cov cai.
Vim tias 4NS tuaj yeem ua haujlwm hauv qhov chaw muaj viscosity siab, tsis tas yuav txhaj roj diesel. Qhov no, nyob rau hauv lem, txo tus nqi los ntawm $2,000 ib hnub twg. Tsis tas li ntawd, lub twj tso kua mis ua haujlwm tau zoo dua thaum siv cov xov xwm viscous, txo kev siv hluav taws xob ntau dua 40% txog 65 kW. Qhov no txuag cov nqi hluav taws xob ntau dua, tshwj xeeb tshaj yog tom qab qhov kev sim ua tiav thaum Lub Ob Hlis 2020, lub twj tso kua mis centrifugal thib ob kuj tau hloov nrog 4NS.
