Electromagnetic flowmeter (EMF), tseem hu ua magmeter / mag flowmeter, yog cov cuab yeej siv dav siv los ntsuas cov dej ntws ntawm cov kua hluav taws xob hauv kev lag luam thiab hauv nroog. Cov cuab yeej muaj peev xwm muab kev txhim khu kev qha thiab tsis cuam tshuam qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas Faraday txoj cai, haum rau cov kua nruab nrab nrog qhov tsim nyog conductivity.
Nws induced electromotive force E tuaj yeem qhia los ntawm cov qauv hauv qab no:
E = KBVD
Qhov twg
K = Flowmeter tas mus li
B = Sib nqus induction siv
V= txhais tau tias ntws nrawm nyob rau hauv ntu ntu ntawm ntsuas yeeb nkab
D = Sab hauv txoj kab uas hla ntawm ntsuas yeeb nkab
Txoj Cai Ua Haujlwm
Lub hauv paus ntsiab lus ntawm kev ua haujlwm rau mag flowmeter yog Faraday txoj cai ntawm electromagnetic induction. Nws hais tias thaum tus neeg xyuas pib txav los ntawm qhov chaw sib nqus, lub zog electromotive yuav raug ntxias.
Tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm electromagnetic flowmeter lub lag luam, conductive kua ntws los ntawm cov yeeb nkab ntawm lub twj paj nruag ua hauj lwm raws li tus neeg xyuas pib. Ib khub ntawm cov coils tsim ib qho chaw sib nqus sib nqus perpendicular rau cov kev taw qhia ntws. Cov kab magnetic teb yuav raug txiav los ntawm kev ntws. Induced electromotive quab yuam yog li generated thiab tom qab ntawd hnov los ntawm ib tug khub ntawm hlau electrodes thiab ua tiav rau hauv cov qauv hluav taws xob teeb liab tso zis.
Qhov zoo ntawm Magnetic Flow Measurement
Structure Simplicity:EMF txoj kev tsim kho tsis muaj qhov txav mus los, uas nws qhov tsis tuaj yeem txo cov khoom siv kho tshuab thiab kev saib xyuas. Kuj tsis tshua muaj kev cuam tshuam hauv nws cov yeeb nkab ntsuas uas tuaj yeem ua rau muaj kev cuam tshuam ntawm lub taub hau siab thiab txhaws ntawm qhov nruab nrab viscous.
Tsawg mounting xav tau:Kev txhim kho ntawm EMF yuav tsum tau luv luv ntawm qhov nce thiab qis qis cov kav dej ncaj nraim. Ua haujlwm ntawm nws tus kheej, lub mag flowmeter tsis tas yuav muaj qhov sib txawv ntawm qhov sib txawv los pab nws ntsuas. Flow tuaj yeem ntsuas nyob rau hauv ob qho tib si kev taw qhia, txo kev txwv rau kev taw qhia 'meter' thiab tsim nyog rau kev siv rov qab khiav xyuas.
Compatibility:Mag flow ntsuas tuaj yeem pom qhov ua haujlwm ruaj khov thiab txhim khu kev qha uas tsis cuam tshuam los ntawm lub cev nruab nrab ntawm qhov siab, qhov kub thiab txias, ntom thiab viscosity. Customizable hauv ob sab phlu cov ntaub ntawv thiab electrode hlau cab los tiv thaiv corrosion thiab hnav resistant xav tau, muaj feem xyuam rau ntau yam aggressive chemical, abrasive slurry, thiab huv si yuav tsum tau ua kua.
Qhov tseeb:Electromagnetic mus kom ze muaj qhov ntsuas qhov tseeb ntawm ntau yam kev ntsuas qhov ntsuas ntsuas. EMF qhov tseeb yog feem ntau ± 0.5% rau ± 0.2% ntawm kev nyeem ntawv.
Kev txwv
Conductivity yuav tsum tau:Kev ntsuas dej ntawm EMF yuav tsum muaj cov conductivity txaus (≥5μS / cm). Yog li cov roj thiab cov kua uas tsis yog-conductive yog dhau qhov ncav cuag ntawm electromagnetic flow ntsuas. Cov khoom lag luam uas tsis yog cov khoom siv hluav taws xob zoo li cov dej huv huv, cov kuab tshuaj organic thiab cov khoom siv roj tsis muaj peev xwm siv txoj kev saib xyuas kev ntws no.
Cov yeeb nkab puv puv:Kev ua haujlwm ntawm EMF yuav tsum muaj tag nrho submersion thiab txuas txuas ntxiv ntawm electrodes nrog cov kua dej conductive. Yog li ntawd thaum lub sij hawm ntsuas tus txheej txheem yuav tsum xyuas kom meej tias cov yeeb nkab seem ntawm EMF yog tag nrho nrog nruab nrab nyob rau hauv thiaj li yuav ua tau kom pom kev ua tau zoo.
Daim ntawv thov
Raws li nws cov kev ntsuas tshwj xeeb, electromagnetic flowmeter yog qhov tshwj xeeb zoo rau kev ntsuas cov kua dej hauv cov xwm txheej xws li:
Kev Siv Dej:Kev ntsuas cov dej hauv dej nyoos thiab qhov hluav taws xob kho cov dej ntws rau kev tswj hwm dej.
Kev kho dej phwj tuaj: Ntsuas cov dej phwj hauv nroog, cov dej ntws tawm hauv lub nroog, thiab cov sludge nrog cov khoom tsim nyog.
Tshuaj:Ntsuas ntau yam acids, alkali, ntsev tov, thiab lwm yam corrosive media uas siv cov ntaub ntawv corrosion-resistant thiab electrode.
Haus dej:Ntsuas cov khoom siv raw, cov khoom nruab nrab thiab cov khoom tiav thaum lub sij hawm tsim cov mis nyuj, kua txiv hmab txiv ntoo, dej cawv thiab lwm yam dej haus.
Metallurgy:Ntsuas cov ntxhia slurry, tailing slurry, thee slurry dej hauv ore ua nrog cov khoom hnav-resistant.
Zog:Ntsuas cov dej txias txias, condensate, tshuaj kho cov kua hauv cov txheej txheem fais fab, thiab lwm yam.
