Kunzwisisa Zvinoitwa neElectromagnetic Flowmeters: Ndezvipi Zvinwiwa Zvavanogona Kuyera?
Ma electromagnetic flowmeters anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwekugona kwawo kuyera kuyerera kwemvura inoyerera. Midziyo iyi inozivikanwa nekuvimbika kwayo uye kushandiswa kwayo kwakasiyana-siyana, zvichiita kuti ikwanise kushandiswa kwakasiyana-siyana. Zvisinei, mubvunzo unowanzo bvunzwa ndewekuti, "Chipimo chemagetsi chinogona kuyera rudzii rwemvura?"
Kuti tipindure mubvunzo uyu, zvakakosha kunzwisisa misimboti iri shure kwema electromagnetic flow metres. Midziyo iyi inoshanda zvichibva pamutemo waFaraday we electromagnetic induction, uyo unoti kana kondakita ikapfuura nemumunda wemagineti, voltage inokonzereswa mukondakita. Ne electromagnetic flowmeter, mvura inokonzeresa inoshanda se kondakita inofamba uye simba remagineti rinogadzirwa nema coils e flowmeter. Nekuyera voltage inokonzereswa, flow meter inogona kuona nemazvo mwero wekuyerera kwemvura.
Nekuda kweiyi nzira yekushanda, ma electromagnetic flowmeters akagadzirirwa kuyera kuyerera kwezvinoyerera zvinofambisa mvura. Izvi zvinoreva kuti mvura inofanira kunge iine mwero wakati we conductivity kuti flow meter ishande zvakanaka. Kazhinji, zvinwiwa zvine conductivity shoma ye5 µS/cm (microSiemens per centimeter) zvakakodzera kuyera ne electromagnetic flow metres.
Mienzaniso yakajairika yezvinwiwa zvinogona kuyerwa nema electromagnetic flow mita zvinosanganisira mvura, acids, alkalis, uye mishonga yakasiyana-siyana yemakemikari. Zvinwiwa izvi zvinowanzova nemazinga ekufambisa anodiwa kuti zvive nechokwadi chekuyera kuyerera kwakarurama. Pamusoro pezvo, hunhu hwe electromagnetic flow mita husingapindike hunoita kuti zvikodzere kushandiswa nezvinwiwa zvinogumbura kana zvinoparadza nekuti hapana zvikamu zvinofamba kana zvinodzivisa mukati menzira yekuyerera zvinogona kukuvara.
Zvakakosha kuziva kuti kunyange zvazvo ma electromagnetic flow meter akakodzera kuyera mhando dzakasiyana dze conductive liquids, pane zvimwe zvipingamupinyi zvekufunga nezvazvo. Semuenzaniso, zvinwiwa zvine conductivity yakaderera, zvakaita semafuta akachena kana mahydrocarbon, zvingasakodzera kuyera ne electromagnetic flowmeter. Muchiitiko ichi, mamwe matekinoroji ekuyera flow akadai se ultrasonic kana thermal mass flow meters angave akakodzera.
Pamusoro pezvo, kuvapo kwemabubbles kana zvidimbu zvakasimba mumvura kuchakanganisa kurongeka kwekuyera kwe electromagnetic flowmeter. Mvura yacho inofanira kuchengetedzwa isina mabubbles nemarara kuti iwane kuverenga kwekuyerera kwakavimbika.
Muchidimbu, ma electromagnetic flow meter anokwanisa kuyera mhando dzakasiyana dzemvura dzinofambisa mvura, kusanganisira mvura, acids, alkalis, uye makemikari. Magadzirirwo awo asingapindi uye kunyatsoita kuti ave sarudzo yakakurumbira yekuyera kuyerera kwemvura mumaindasitiri akadai sekurapa mvura, kugadzira makemikari, uye kugadzira chikafu nezvinwiwa. Zvisinei, zvakakosha kufunga nezvekuyerera kwemvura uye kuchena kwayo kuti ive nechokwadi chekuti electromagnetic flowmeter inoshanda zvakanaka. Nekunzwisisa kugona uye miganhu ye electromagnetic flowmeter, vashandisi vanogona kuita sarudzo ine ruzivo maererano nekukodzera kwavo kushandiswa kwekuyerwa kwemvura.
