Los ntawm cov lus xaiv, koj tuaj yeem pom cov flowmeters siv nyob rau hauv slurry uas muaj particle fibers: txawv siab flowmeters muaj xws li lub luj tshib, wedge-shaped leeg, electromagnetic flowmeters, Doppler ultrasonic flowmeters,vortex flowmeters, Lub hom phiaj flowmeter, Coriolis huab hwm coj flowmeter, thiab lwm yam raws li kev siv cov xwm txheej thiab kev ntsuas kev ua tau zoo ntawm ntau yam flowmeters, electromagnetic flowmeters yog thawj qhov kev xaiv rau kev ntsuas slurry txaus, tshwj tsis yog tias cov ntsuas slurry tsis yog-conductive lossis muaj ferromagnetic hais, thiab kev ntsuas. pipeline system tsis pub raug txiav tawm kom nkag mus rau qhov ntws sensor. xaiv lwm flowmeter. Raws li cov lus ceeb toom, ntau xyoo ntawm kev siv hauv kev ntsuas qhov ntws ntawm cov thee-dej slurry nrog pulverized thee cov ntsiab lus txog li 65 feem pua yog suav tias yog qhov zoo tshaj plaws electromagnetic flowmeter.
Sib txawv siab flowmeters tuaj yeem siv los ntsuas slurry. Ntxiv nrog rau lub luj tshib, cov leeg zoo li cov hlab ntsha thiab cov hlab ntsha annular, qhov sib txawv ntawm qhov sib txawv kuj tseem siv tau rau cov phiajcim orifice thiab eccentric orifice daim hlau thaum cov khoom theem me me. Venturi raj kuj siv rau kev ntsuas. .
Doppler ultrasonic flowmeter tuaj yeem ntsuas yam tsis tau txiav cov yeeb nkab thiab clamping ib qho ultrasonic transducer (kev sojntsuam) sab nraum cov yeeb nkab, tab sis qhov ntsuas qhov tseeb tsis siab.
Vortex flowmeter tsuas yog ntsuas cov khib nyiab uas muaj cov hmoov me me, thiab cov ntsiab lus ntawm cov khoom yog loj lossis fibrous yuav ua rau lub suab nrov thiab siv tsis tau.
Lub hom phiaj flowmeter yog siv rau cov kua ntws xws li cov roj hnyav lossis cov roj seem uas muaj cov roj pulverized, thiab cov hom phiaj flowmeter yog siv.
Qhov kev paub ntawm Coriolis huab hwm coj flowmeter siv rau kev ntsuas slurry feem ntau haum rau nws txoj kev ntsuas lub raj ncaj nraim, tab sis tsis muaj ntau yam kev siv.
Kev xaiv rau kev ntsuas loj ntawm cov kua hauv cov kav dej kaw
Cov dej ntws loj uas tau hais los saum no tsis yog hais txog qhov "kuj loj txaus" thaum qhov ntws nrawm ntawm qee cov yeeb nkab txoj kab uas hla yog siab, tab sis qhov loj txaus ntawm qhov tseeb ntawm qhov ntws. Txij li thaum qhov khiav ceev ntawm cov kua thauj los ntawm lub raj xa dej muaj qee qhov ntau, qhov kev lag luam khiav nrawm ntawm cov kua dej uas tsis muaj viscosity feem ntau yog 1 ~ 3m / s. Yog li ntawd, qhov kev ntsuas "loj ntws" hais txog ntawm no yog hais txog kev ntsuas ntawm cov kav dej loj ntws.
Feem ntau hais lus, lub flowmeter nrog cov yeeb nkab txoj kab uas hla hauv qab DN300 yog hu ua me me thiab nruab nrab yeeb nkab txoj kab uas hla flowmeter, lub saum toj no DN300 ~ DN400 yog hu ua cov yeeb nkab loj txoj kab uas hla flowmeter, thiab ib tug saum toj no DN1200 yog hu ua ntxiv loj yeeb nkab diameter flowmeter. Feem ntau, cov kua dej ntsuas ntawm cov kav dej loj loj yog cov dej, thiab ntxiv rau cov dej, muaj cov khoom siv roj av. Feem ntau, qhov loj-inch flowmeters suav nrog qhov sib txawv siab flowmeters,electromagnetic flowmeters, ultrasonic flowmeters thiab insertion flowmeters. Kuj tseem muaj qhov zoo hloov pauv flowmeters thiab turbine flowmeters rau DN300 ~ DN500.
1. Kev teeb tsa
Cov kev teeb tsa kev teeb tsa feem ntau yog nyob ntawm seb txoj kev ntsuas puas tuaj yeem tso cai rau cov yeeb nkab ntws tawm thiab kev ua haujlwm raug tshem tawm, seb nws puas tau tso cai rau kev tho qhov ntawm cov yeeb nkab, thiab seb nws puas raug tso cai txiav tawm cov yeeb nkab ntws mus rau. nruab lub flow sensor.
Yog tias lub ntsuas ntws tau tso cai txiav tawm cov yeeb nkab ntws, electromagnetic flowmeters, ultrasonic flowmeters nrog ntsuas cov yeeb nkab seem, qhov zoo hloov pauv flowmeters thiab turbine flowmeters tuaj yeem xaiv.
Extrapolation transducer ultrasonic flowmeters thiab insertion flowmeters tuaj yeem xaiv yog tias qhov drilling qhov hauv cov raj xa dej tau tso cai.
Yog tias cov kev cai saum toj no tsis raug tso cai, koj tsuas tuaj yeem xaiv lub ntsuas ntsuas ultrasonic nrog rau sab nraud clip-on transducer.
2. Kev ntsuas qhov tseeb
Rau kev saib xyuas kev hloov pauv uas yuav tsum tau ntsuas qhov tseeb thiab cov kua dej tsis zoo, ultrasonic flowmeters nrog ntsuas cov yeeb nkab, ntau channel ultrasonic flowmeters, vortex flowmeters, thiab electromagnetic flowmeters kuj tuaj yeem xaiv rau cov kua dej.
Rau kev tswj piv, qhov sib txawv siab Venturi raj thiab sab nraud clamping transducerultrasonic flowmetertuaj yeem xaiv nrog qhov ntsuas qhov tseeb qis dua. Optional insertion flowmeter nrog tsawg ntsuas qhov yuav tsum tau muaj.
3. Kev poob siab (tus nqi siv hluav taws xob)
Tus nqi siv hluav taws xob ntawm kev ntsuas loj txaus suav rau feem ntau ntawm cov nqi ntsuas kev khiav hauj lwm, kev poob siab thiab (tus nqi siv hluav taws xob) xws li qhov sib txawv siab Venturi, qhov zoo hloov pauv flowmeter thiab turbine ntws suav. Qhov me me yog qhov ntxig flowmeter, thiab qhov tsis muaj qhov poob siab yog lub electromagnetic flowmeter.
