An electromagnetic flowmeter mudziyo unoshandiswa kuyera mafambiro ezvinwiwa zvinobatika.
Kusiyana nechinyakare flowmeters, electromagnetic flowmeters inoshanda zvichibva pamutemo weFaraday wemagetsi induction uye kuyera kuyerera kwezvinoyerera zvinoyerera zvichibva pamagetsi emagetsi anogadzirwa kana conductive fluid inopfuura nekunze kwemagineti.
Chimiro che electromagnetic flowmeter inonyanya kuve nemagnetic circuit system, yekuyeresa conduit,electrodes, imba, lining, uye converter.
Inoshanda sei?
1. Magnetic munda chizvarwa
Kana iyo flowmeter ichishandiswa, iyo electromagnetic coil inogadzira magineti perpendicular kune nzira yekuyerera kwemvura. Iyi magnetic field yakagadzikana uye yakafanana, ichiva nechokwadi chekuyera kunoenderana mhedzisiro.
2. Voltage induction
Kana iyo conductive fluid ichiyerera nepamagineti, inoyambuka mitsara yemagineti. Zvinoenderana nemutemo waFaraday, kufamba uku kunokonzera voltage mumvura. Hukuru hwemagetsi aya hunoenderana nekuyerera kwemvura.
3. Kuonekwa kwemagetsi
Electrodes akaiswa muchubhu inoyerera anoona iyo induced voltage. Nzvimbo ye electrodes inokosha; ivo vanowanzoiswa kumusoro uye pasi pechubhu inoyerera kuti vaone kuverenga kwakaringana zvisinei nekuyerera kwe curve.
4. Signal processing
Iyo yakaonekwa voltage siginecha inotumirwa kune transmitter, iyo inogadzirisa ruzivo. Iyo transmitter inoshandura voltage kuita chiyero chekuyerera, chinowanzo ratidzwa mumayuniti akadai marita paminiti (L/min) kana magaroni paminiti (GPM).
5. Zvakabuda:
Pakupedzisira, iyo data inoyerera inogona kuratidzwa pachiratidziro, yakanyorwa kuti iongororwe mune ramangwana, kana kuendeswa kune yekudzora sisitimu yekutarisa-nguva chaiyo uye kutonga.
Zvakanakira zve electromagnetic flowmeter
Zvakanakira zvemagetsi emagetsi zvinoyerera zvinonyanya zvinosanganisira kuyera-chaiyo kuyerwa, pasina kumanikidzwa kurasikirwa, yakafara reshiyo, yakasimba corrosion kuramba, yakakura application renji, inonzwisa tsitsi, kuisirwa nyore, dhijitari masaini kugadzirisa, yakasimba anti-kupindira, nezvimwe.
Kushandiswa kwe electromagnetic flowmeter
● Kugadziriswa kwemvura uye tsvina: Chengetedza kuyerera kwechirimwa chekurapa kuti uone kutevedza mitemo yezvakatipoteredza.
● Kugadziriswa kwemakemikari: Kuyera kuyerera kwezvinwiwa zvinopisa kana kuti viscous mukugadzirwa kwemakemikari.
● Indasitiri yezvekudya nezvinwiwa: Iva nechokwadi chekuyerwa kwakaringana kwekuyerera kwezvinwiwa zvakaita semuto, mukaka, uye muto, izvo zvakakosha pakudzora kunaka.
● Pharmaceutical: Chengetedza kuyerera kwezvinhu zvinoshanda uye zvinonyungudutsa mumishonga yemishonga.
Isu tinopawopasi electrodes (grounding mhete)kushandiswa mumamiriro ezvinhu apo electromagnetic flowmeters inoda hutungamiri huripo, kubviswa kwekuvhiringidza, uye kuve nechokwadi chekuvimbika kwechiratidzo chechiratidzo.
