Hauv kev tsim khoom lag luam, ntab loj yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau cov khoom zoo, kev tsim khoom, thiab kev nyab xeeb ntawm kev ua haujlwm. Lub glide meter, raws li cov cuab yeej tseem ceeb rau kev ntsuas waft, nws txoj kev xaiv tsis yog tsuas yog cuam tshuam nrog qhov tseeb ntawm cov ntaub ntawv loj tab sis kuj tseem txiav txim siab qhov sib npaug ntawm tag nrho cov cuab yeej tsim khoom thiab tus nqi - kev ua tau zoo ntawm kev yuav khoom.
Kauj Ruam 1: Qhia kom meej cov ntsiab lus ntawm qhov ntsuas nruab nrab
- Hom Nruab Nrab: Qhia meej meej ntawm cov kua, roj lossis chav. Piv txwv li, electromagnetic mus nrog cov ntsuas ntws tsuas yog tsim nyog rau cov dej haus thiab tsis tuaj yeem ntsuas cov pa roj lossis tsis yog - dej haus xws li roj; vortex drift meters yog tsim nyog rau gases, kua, thiab chav, nrog versatility ruaj khov, tab sis tam sim no lawv tsis tsim nyog rau kev tshaj tawm nrog ntau viscosity.
- Cov Khoom Nruab Nrab: suav nrog viscosity, ntom, corrosiveness, abrasiveness, turbidity, thiab seb puas muaj impurities. Piv txwv li, rau kev tshaj tawm nrog cov viscosity ntau dhau (xws li cov roj hnyav, asphalt), cov khoom siv hluav taws xob zoo los yog cov khoom siv waft yuav tsum raug xaiv, thaum lub tshuab turbine mus nrog cov ntsuas ntws yog inclined mus jamming vim ntau viscosity thiab tsis haum lawm; rau corrosive media, glide meters ua los ntawm corrosion-cov tshuaj tiv thaiv yuav tsum tau xaiv kom deb ntawm cov cuab yeej raug mob los ntawm txoj kev nruab nrab erosion.
Feem ntau yuam kev: qhov muag tsis pom kev txiav txim siab ntawm kev mus nrog lub ntsuas dej ntws dhau los ua kom pom tseeb qhov nruab nrab tsis muaj. Piv txwv li, kev siv lub ntsuas hluav taws xob hluav taws xob los ntsuas roj (tsis yog-cov khoom nruab nrab) cuam tshuam hauv kev ntsuas cov ntaub ntawv tsis raug; Kev siv cov hlau tsis tshua muaj hlau waft ntsuas ntsuas corrosive media xws li hydrochloric acid ua rau cov cuab yeej ceev corrosion thiab lub neej luv luv.
Kauj Ruam 2: Txiav txim siab qhov Flow Range thiab ntsuas qhov yuav tsum tau muaj
- Flow Range Determination: Ua ntej, ua kom meej qhov tsawg kawg nkaus, ntws zoo tib yam, thiab feem ntau mus nrog qhov ntws ntawm qhov nruab nrab hauv cov raj xa dej tag nrho los ntawm kev ua haujlwm tiag. Kev xaiv mus nrog lub ntsuas ntsuas ntsuas qhov sib txawv yuav tsum tau cowl qhov zoo tib yam glide thiab feem ntau ntws, thiab qhov tsawg kawg nkaus waft yuav tsum nyob rau hauv qhov zoo ntsuas sib txawv ntawm lub waft 'meter' (feem ntau, qhov tsis tu ncua mus nrog cov ntws yuav tsum yog 50% -80% ntawm qhov ntsuas feem ntau sib txawv ntawm kev mus nrog cov ntsuas ntws). Piv txwv li, yog tias qhov nruab nrab ntawm qhov nruab nrab txhua hnub yog 50m³ / h thiab qhov glide tshaj plaws yog 80m³ / h, qhov ntsuas qhov sib txawv ntawm 0-100m³ / h yog qhov tsim nyog.
- Kev ntsuas qhov yuav tsum tau muaj: Txiav txim siab qhov yuav tsum tau muaj qhov tseeb theem raws li kev tsim khoom thiab kev tswj hwm kev xav tau. Cov kev lag luam sib txawv thiab cov xwm txheej software muaj ib qho - ntawm -ib - yam uas yuav tsum tau muaj. Piv txwv li, nyob rau hauv kev lag luam tshuaj, qhov chaw uncooked daim ntaub metering thiab cov khoom batching muaj kev koom tes, siab - raug mus nrog cov flow meters (qhov tseeb℃tsawg dua los yog sib npaug rau ± 0.5%) yog yuav tsum tau, xws li loj glide meters los yog siab -zoo displacement ntab meters; Hauv kev lag luam dej thiab cov kav dej, qhov chaw tsim nyog rau qhov tseeb qhov tseeb yog qhov tsawg heev, tsis tu ncua vortex mus nrog cov ntsuas ntws los yog electromagnetic mus nrog cov ntsuas ntsuas (qhov tseeb ± 1.0%-± 2.5%) tuaj yeem xaiv. Nws yuav tsum tau hais tias qhov ntau dua qhov tseeb ntawm glide meter, tus nqi ntau dua. Qhov muag tsis pom kev mus nrhiav ultra- qhov raug siab yuav ua kom cov nqi khoom loj thiab cov nqi khaws cia tshwj tsis yog cov kev xav tau tiag tiag.
Feem ntau yuam kev : Xaiv lub float meter nrog ib tug drift sib txawv uas tam sim no tsis noj qab nyob zoo qhov kev thov, los yog dig muag nrhiav qhov tseeb ntau dhau. Piv txwv li, qee tus neeg ua haujlwm yuav khoom xaiv lub ntsuas ntab ntab uas muaj qhov sib txawv loj heev rau "tso peev xwm", ua rau muaj qhov tseeb qis hauv kev siv tiag; qee qhov kev xaiv qis- qhov tseeb glide meters rau cov nqi muag khoom muag, uas ua rau muaj qhov ntsuas tsis raug ntawm cov khoom tsis zoo thiab cov khoom lag luam, cuam tshuam rau kev tsim khoom zoo thiab cov txiaj ntsig nyiaj txiag.
Kauj Ruam 3: Paub meej tias cov kav dej thiab cov kev xav tau ntawm kev teeb tsa
- Pipeline Parameters: Qhia meej txog txoj kab uas hla (DN), cov khoom siv kav dej, qhov ntev ntawm cov kav dej, thiab seb puas muaj lub luj tshib, li qub, reducers, lossis lwm yam nyob ze ntawm qhov chaw teeb tsa. Piv txwv li, feem ntau waft meters yuav tsum tau ib tug zoo ncaj yeeb nkab ib feem ua ntej thiab tom qab teeb tsa kom paub meej qhov sib npaug ntawm qhov nruab nrab glide thiab kom deb ntawm qhov muaj feem cuam tshuam ntawm glide cuam tshuam ntawm qhov tseeb ntawm qhov loj. Yog tias thaj tsam ntawm cov kav dej raug txwv thiab qhov chaw cov yeeb nkab ncaj tsis txaus, nws yog ib qho tseem ceeb kom xaiv ib lub ntsuas qhov ntsuas uas tsis muaj qhov cuam tshuam rau cov yeeb nkab ncaj, xws li electromagnetic drift meter lossis ultrasonic drift meter.
- Ib puag ncig kev teeb tsa: Xav txog kev teeb tsa ib puag ncig ntawm kev mus nrog lub ntsuas dej ntws, suav nrog qhov ntsuas kub, av noo, plua plav, kev co, hluav taws xob cuam tshuam, thiab seb nws puas nyob hauv qhov chaw tawg. Piv txwv li, nyob rau hauv ib puag ncig uas muaj zog electromagnetic cuam tshuam, nws yog ib qho tseem ceeb uas yuav tau xaiv ib tug mus nrog lub flow meter nrog sturdy anti- cuam tshuam kev ua tau zoo; nyob rau hauv qhov chaw tawg, nws yog ib qho tseem ceeb los xaiv qhov tawg - pov thawj glide meter uas ua tau raws li qhov sib thooj tawg - qib pov thawj.
Feem ntau yuam kev 3: Tsis quav ntsej cov kav dej ua ntej thiab teeb tsa cov cai, ua rau muaj teeb meem nyuaj lossis ntsuas tsis raug. Piv txwv li, muab tso rau hauv lub vortex ntab 'meter' ze rau lub luj tshib lossis lub valve txwv tsis pub ncaj cov yeeb nkab seem, ua rau muaj qhov tsis zoo loj; muab tso rau hauv ib lub waft meter tsis tu ncua nyob rau hauv ib qho chaw tawg, lub ntsiab rau conceivable kev ruaj ntseg txaus ntshai.
Kev txiav txim siab ntawm waft meters yog ib qho kev ua haujlwm uas yuav tsum tau ua tiav qhov ntsuas nruab nrab ntawm qhov ntsuas qhov ntsuas, ntab ntau yam, qhov tseeb qhov tseeb, cov kav dej, teeb tsa ib puag ncig, ntab meter hom, cov khoom tsim nyog, thiab tom qab- kev pabcuam muag. Nyob rau hauv txoj kev txiav txim siab tseeb, nws tseem yog qhov tseem ceeb rau kev sib xyaw cov kev tsim khoom raug tsim nyog thiab nrhiav kev tawm tswv yim los ntawm cov kws tshaj lij cov neeg ua haujlwm yog tias qhov tseem ceeb rau ntxiv rau txhim kho kev tshawb fawb thiab kev tsim nyog ntawm kev xaiv.
