Chiyero chemagetsi chinoyerera (EMF), chinozivikanwawo semagmeter/mag flowmeter, chishandiso chinoshandiswa zvakanyanya pakuyera mwero wekuyerera kwemvura inofambisa magetsi mumaindasitiri nemakanzuru. Chishandiso ichi chinogona kupa mhinduro yakavimbika uye isingapindike yekuyera kuyerera kwemvura uchishandisa mutemo waFaraday, yakakodzera nzvimbo yemvura ine conductivity yakakodzera.
Simba rayo remagetsi rinokonzereswa E rinogona kuratidzwa nenzira inotevera:
E=KBVD
Kupi
K = Chinotenderera cheflowmeter
B = Kusimba kwemagetsi
V= avhareji yekumhanya kwemvura muchikamu chakayambuka chepombi yekuyera
D= Dhayamita yemukati yepombi yekuyera
Nheyo yekushanda
Nheyo huru yekushanda kwemuchina wemagetsi (mag flowmeter) mutemo waFaraday we electromagnetic induction. Unotaura kuti kana kondakita ichifamba nemumunda wemagineti, simba remagetsi rinokonzereswa.
Kunyanya kana paine mashandiro e electromagnetic flowmeter, mvura inoyerera nepaipi yemudziyo inoshanda se conductor. Peya ye coils inogadzira simba remagineti rakafanana rakatarisa divi rekuyerera. Mitsetse yesimba remagineti inochekwa nekuyerera. Simba remagineti rinokonzereswa rinogadzirwa uye rinozonzwa nema electrodes maviri esimbi uye rinogadziriswa kuita standard electrical signal output.
Mabhenefiti eKuyera Kuyerera kweMagineti
Zviri nyore pakuvaka:Kugadzirwa kweEMF hakuna zvikamu zvinofamba, izvo kusavapo kwayo kunoderedza kupera kwemidziyo uye kudiwa kwekugadzirisa. Hapanawo chipingamupinyi chiri mukati mepombi yayo yekuyera chinogona kukonzera kudonha kwemusoro wekumanikidza uye kuvharika kwechinhu chinonamira.
Zvinodiwa zvishoma zvekuisa:Kuiswa kweEMF kunoda kureba kupfupi kwezvikamu zvepombi dzakatwasuka kumusoro nekudzika. Ichishanda yega, mag flowmeter haidi differential pressure transmitter kuti ibatsire kuyera kwayo. Kuyerera kunogona kuyerwa kumativi ese, zvichideredza kuganhurirwa kwekutarisa mita uye kwakakodzera kushandiswa kwe reverse flow monitoring.
Kuenderana:Kuyerwa kwemagetsi kunogona kuratidza kushanda kwakasimba uye kwakavimbika kusingakanganiswi nematanho epakati emuviri ekumanikidzwa, tembiricha, huwandu uye kusimba. Zvinhu zvemukati zvinogadziriswa uye simbi dzemagetsi cab zvinodzivirira ngura uye zvinodzivirira kupfeka, zvinoshanda kune akasiyana-siyana emakemikari akasimba, slurry, uye sanitary required liquid media.
Kururama:Nzira yemagetsi inoshandisa nzira yekuyera mafambiro emvura nenzira chaiyo pakati penzira dzakasiyana-siyana dzekuyera mafambiro emvura. Kururama kweEMF kunowanzova ±0.5% kusvika ±0.2% yekuverenga.
Miganhu
Kufambiswa kwemhepo kunodiwa:Mvura yekuyera yeEMF inodiwa kuti ive nemhepo yakakwana inofambisa mvura (≥5μS/cm). Saka gasi nemvura isingafambise mvura hazvikwanisike kuyerwa nekuyerera kwemagetsi. Zvinhu zvakajairika zvemaindasitiri zvisina kufambisa mvura zvakaita semvura yakacheneswa nemhepo, zvinonyungudutsa organic uye zvigadzirwa zvemafuta hazvikwanise kushandisa nzira iyi yekutarisa kuyerera kwemvura.
Pombi yakazara zvizere:Kushanda kweEMF kunoda kunyudzwa kwakazara uye kubatana nguva dzose kwemaerekitiroti nemvura inofambisa mvura. Saka panguva yekuyera, maitiro acho anofanira kuve nechokwadi chekuti chikamu chepaipi cheEMF chazara nemedium kuti chibudirire zvakanaka.
Kushandiswa
Zvichibva pamusimboti wayo wekuyera wakasiyana, electromagnetic flowmeter inonyanya kukodzera kuyera mvura dzinofambisa mvura mumamiriro ezvinhu akadai se:
Kupa Mvura:Kuyera mvura isina kubikwa inopinzwa uye mvura yakacheneswa inobuda kuti itarisirwe zvakanaka.
Kurapa Tsvina: Kuyera tsvina yemumaguta, tsvina yemumaindasitiri, uye tsvina nekufambisa mvura zvakakwana.
Kemikari:Kuyera maasidhi akasiyana-siyana, alkali, munyu, nezvimwe zvinhu zvinoparadza zvakanyanya tichishandisa machira anodzivirira ngura nezvinhu zvemagetsi.
Chinwiwa:Kuyera zvinhu zvakabikwa, zvepakati uye zvakagadzirwa panguva yekugadzira mukaka, muto, zvinwiwa zvine doro nezvimwe zvinwiwa.
Kugadzira simbi:Kuyera slurry yemaminerari, slurry yemusana, mvura yemarasha iri mukugadzirwa kwematombo nezvinhu zvisingapfeki.
Simba:Kuyera mvura inotonhorera inotenderera, condensate, mishonga yekurapa makemikari mumabasa emagetsi, nezvimwewo.
Shanghai Wangyuanane ruzivo rwemakore anopfuura makumi maviri mukugadzira nekushandira zvishandiso zvekuyera. Ruzivo rwedu rwakakura rwehunyanzvi uye zvidzidzo zvemimwe minda ine marudzi ese ema flow metres zvinotigonesa kupa mhinduro dzekutarisa kuyerera kwemvura dzinoenderana nezvinodiwa zvako chaizvo. Kana paine mibvunzo nezve electromagnetic flow metres, ndapota usazeza kutibata.
