An electromagnetic flowmeter ndi chipangizo chomwe chimagwiritsidwa ntchito kuyeza kuthamanga kwamadzimadzimadzi.
Mosiyana ndi ma flowmeters achikhalidwe, ma electromagnetic flowmeters amagwira ntchito motengera lamulo la Faraday la kulowetsedwa kwamagetsi ndi kuyeza mayendedwe amadzimadzi amadzimadzi potengera mphamvu ya electromotive yomwe imapangidwa pomwe madzimadzi a conductive amadutsa kumunda wakunja kwa maginito.
Mapangidwe a electromagnetic flowmeter makamaka amakhala ndi maginito ozungulira, njira yoyezera,ma elekitirodi, nyumba, mpanda, ndi chosinthira.
Zimagwira ntchito bwanji?
1. M'badwo wa maginito
Pamene flowmeter ntchito, ndi electromagnetic koyilo amapanga maginito munda perpendicular kwa malangizo otaya madzi. Mphamvu ya maginitoyi ndi yokhazikika komanso yofanana, kuwonetsetsa kuti muyeso umakhala wofanana.
2. Kulowetsa magetsi
Madzi amadzimadzi akamadutsa mumlengalenga, amadutsa mizere ya maginito. Malingana ndi lamulo la Faraday, kayendetsedwe kameneka kamapangitsa kuti magetsi azikhala mumadzimadzi. Kukula kwa votejiyi kumayenderana ndi kuthamanga kwamadzimadzi.
3. Kuzindikira mphamvu yamagetsi
Ma electrode ophatikizidwa mu chubu chotuluka amazindikira voteji yomwe imapangitsa. Malo a electrode ndi ofunika kwambiri; nthawi zambiri amayikidwa pamwamba ndi pansi pa chubu chothamanga kuti atsimikizire kuwerengedwa kolondola mosasamala kanthu za mayendedwe othamanga.
4. Kusintha kwa ma Signal
Chizindikiro chamagetsi chomwe chapezeka chimatumizidwa kwa transmitter, yomwe imayendetsa chidziwitsocho. Transmitter imatembenuza voteji kukhala muyeso wothamanga, womwe umawonetsedwa m'mayunitsi monga malita pamphindi (L / min) kapena magaloni pamphindi (GPM).
5. Zotulutsa:
Potsirizira pake, deta yothamanga ikhoza kuwonetsedwa pawindo, yolembedwa kuti ifufuze m'tsogolomu, kapena kutumizidwa ku dongosolo loyang'anira nthawi yeniyeni yowunikira ndi kulamulira.
Ubwino wa electromagnetic flowmeter
Ubwino wa ma electromagnetic flowmeters makamaka umaphatikizira muyeso wolondola kwambiri, osataya kupsinjika, kuchuluka kwamitundu yosiyanasiyana, kukana kwa dzimbiri, mitundu yosiyanasiyana ya ntchito, kuyankha tcheru, kuyika kosavuta, kukonza ma siginecha a digito, kusokoneza mwamphamvu, ndi zina zambiri.
Kugwiritsa ntchito electromagnetic flowmeter
● Kuyeretsa madzi ndi madzi otayira: Yang'anirani kayendedwe ka malo opangira mankhwala kuti muwonetsetse kuti akutsatira malamulo a chilengedwe.
● Kukonza mankhwala: Yesani kutuluka kwa zakumwa zowononga kapena zowoneka bwino popanga mankhwala.
● Makampani opanga zakudya ndi zakumwa: Onetsetsani kuti madzi akuyenda bwino monga madzi, mkaka, ndi msuzi, zomwe ndi zofunika kwambiri kuti zisamayende bwino.
● Mankhwala: Yang'anirani kayendedwe ka zinthu zogwira ntchito ndi zosungunulira muzitsulo za mankhwala.
Timaperekansoma electrodes oyambira (mphete zoyatsira)kuti zigwiritsidwe ntchito pomwe ma electromagnetic flowmeters amafunikira chitsogozo chapano, kuchotsa zosokoneza, ndikuwonetsetsa kukhulupirika kwa loop yamagetsi.
