Kev xaiv ntawm electromagnetic flowmeter hauv kev lag luam khoom noj khoom haus
2022-07-26
Electromagnetic flowmeters feem ntau yog siv hauv kev lag luam khoom noj khoom haus flowmeters, uas yog siv los ntsuas qhov ntim ntawm cov kua dej thiab cov slurries hauv cov kav dej kaw, suav nrog cov kua qaub xws li acids, alkalis, thiab ntsev.
Flowmeter kev ua tau zoo rau cov ntawv thov kev lag luam khoom noj yuav tsum muaj cov yam ntxwv hauv qab no:
1. Kev ntsuas tsis cuam tshuam los ntawm kev hloov pauv ntawm cov kua dej ntom ntom, viscosity, qhov kub thiab txias, siab thiab conductivity, 2. Tsis muaj qhov cuam tshuam ntawm qhov ntws hauv lub raj ntsuas
3. Tsis muaj kev poob siab, tsis tshua muaj kev xav tau rau cov kav dej ncaj nraim,
4. Lub converter txais ib txoj kev excitation tshiab, nrog tsawg zog noj thiab siab xoom-point stability.
5. Kev ntsuas qhov ntsuas qhov ntau yog qhov loj, thiab lub flowmeter yog ib qho kev ntsuas bidirectional, nrog rau pem hauv ntej tag nrho, thim rov qab tag nrho thiab qhov sib txawv tag nrho, thiab yuav tsum muaj ntau yam khoom tawm.
Thaum xaiv ib qho electromagnetic flowmeter, thawj zaug paub meej tias qhov ntsuas nruab nrab puas yog conductive. Tus nqi ntws ntawm qhov ntsuas nruab nrab hauv cov pa hluav taws xob muaj hluav taws xob yog qhov zoo dua 2 txog 4m / / s. Hauv cov xwm txheej tshwj xeeb, tus nqi qis qis yuav tsum tsis pub tsawg dua 0.2m / / s. Cov khoom muaj cov khoom siv, thiab cov khoom siv feem ntau yuav tsum tsawg dua 3m / / s kom tsis txhob muaj kev sib txhuam ntau dhau ntawm cov hauv ob sab phlu thiab cov electrode. Rau cov kua dej viscous, qhov loj dua tuaj yeem pab tshem tawm cov nyhuv ntawm cov kua nplaum uas txuas nrog cov electrode, uas yog qhov zoo los txhim kho qhov ntsuas qhov tseeb. Siv. Feem ntau, lub nominal txoj kab uas hla ntawm cov txheej txheem pipeline raug xaiv. Ntawm chav kawm, qhov ntau ntawm cov kua dej hauv cov kav dej yuav tsum tau txiav txim siab tib lub sijhawm. Thaum tus nqi ntws tsawg dhau los yog loj dhau lawm, lub nominal txoj kab uas hla ntawm lub flowmeter yuav tsum raug xaiv nrog rau kev siv cov dej ntws hauv qab qhov chaw ntawm kev ntsuas qhov tseeb. Txais tos tiv tauj peb cov kws tshaj lij kom paub meej ntxiv kev txhawb nqa kev xaiv.
