Electromagnetic flowmeter (EMF), inozivikanwawo semagmeter/mag flowmeter, chiridzwa chinoshandiswa zvakanyanya kuyera kuyerera kweyero yemagetsi conductive fluid mumaindasitiri nemanisipala application. Chiridzwa chacho chinogona kupa yakavimbika uye isingapindire volumetric kuyerera kuyerwa mhinduro inosimudzira mutemo waFaraday, wakakodzera svikiro repakati nemaitiro akakodzera.
Yayo induced electromotive force E inogona kuratidzwa neinotevera formula:
E=KBVD
Kupi
K = Flowmeter nguva dzose
B = Magnetic induction intensity
V= zvinoreva kuyerera kwevelocity muchikamu chemuchinjiko chepipo yekuyeresa
D= Inner dhayamita yekuyeresa pombi
Kushanda Nheyo
Nheyo yakakosha yekushanda kweiyo mag flowmeter mutemo waFaraday wemagetsi induction. Inoti kana conductor ikafamba nepakati pesimba remagineti, simba re electromotive rinobva ragadzirwa.
Kunyanya panyaya ye electromagnetic flowmeter's operation, conductive fluid inoyerera nepapombi yechiridzwa inoshanda se conductor. Peya yemakoiri inogadzira yunifomu yemagineti perpendicular kune kuyerera kwakanangana. Mitsetse yemagnetic field yaizodimburwa nekuyerera. Induced electromotive force saka inogadzirwa uye inozonzwa nepeya yesimbi maelectrode uye inogadziridzwa kuita yakajairwa magetsi chiratidzo kubuda.
Zvakanakira Magnetic Flow Measurement
Maumbirwo ari nyore:Kuvaka kweEMF hakuna zvikamu zvinofamba, izvo kusavapo kunoderedza kupfeka kwemagetsi uye kudiwa kwekugadzirisa. Iko zvakare hakuna kana chipingamupinyi chipi nechipi mukati mepombi yayo yekuyeresa izvo zvinogona kutungamira mukudzika kwemusoro wekumanikidza uye kuvhara kwe viscous medium.
Zvishoma zvekuisa zvinodiwa:Kuiswa kweEMF kunoda kureba kupfupi kumusoro uye kuzasi kwakatwasuka pombi zvikamu. Inoshanda yakazvimiririra, iyo mag flowmeter haidi kusiyanisa kudzvanywa transmitter kubatsira kuyerwa kwayo. Kuyerera kunogona kuyerwa mumativi ese, kudzikisa kurambidzwa kwemamita kutaridzika uye kwakakodzera kushandiswa kwereverse kuyerera kwekutarisa.
Kuenderana:Mag kuyerera kuyerwa kunogona kuratidza yakagadzikana uye yakavimbika mashandiro ayo asingambokanganiswe nemuviri wepakati paramita yekumanikidza, tembiricha, density uye viscosity. Customizable lining materials uye electrode metals cab anti-corrosion uye kupfeka zvinodzivirira zvinodiwa, zvinoshanda kune dzakasiyana siyana dzemakemikari ane hukasha, abrasive slurry, uye hutsanana hunoda mvura media.
Kururama:Electromagnetic nzira inoratidzira yakanyanya kuyera kuyera pakati peakasiyana volumetric kuyerera kuyerera nzira. Kurongeka kweEMF kunowanzo ± 0.5% kusvika ± 0.2% yekuverenga.
Kuganhurirwa
Conductivity inodiwa:Iyo yekuyera fluid yeEMF inodiwa kuti ive yakakwana conductivity (≥5μS/cm). Saka gasi uye isiri-conductive fluid iri kupfuura kusvika kune electromagnetic kuyerera kuyerwa. Zvakajairwa maindasitiri asiri-conductive midhiya senge mvura yakanatswa mvura, organic solvents uye zvigadzirwa zveoiri hazvikwanise kushandisa iyi kuyerera kwekutarisa nzira.
Pombi yakazara yakazara:Kushanda kweEMF kunoda kunyura kwakazara uye kuenderera mberi kwekubatana kwemaelectrode ane conductive fluid. Naizvozvo panguva yekuyera maitiro anofanirwa kuve nechokwadi chekuti pombi chikamu cheEMF chakazadzwa zvachose nepakati kuitira kuti uwane kuita kwakakwana.
Application
Zvichienderana neyakasiyana kuyerwa musimboti, electromagnetic flowmeter inonyanya kukodzera kuyerwa kwezvinoitisa zvinwiwa mumamiriro ezvinhu akadai se:
Mvura:Kuyera kuyerera kwemvura inopinza uye yekubuda yakacheneswa kuyerera kwemvura yekutonga zviwanikwa.
Kugadziriswa kweSewage: Kuyera tsvina yemunisiparati, tsvina yemumaindasitiri, uye matope ane mafambisirwo akakwana.
Kemikari:Kuyera maasidhi akasiyana-siyana, alkali, munyu, uye mamwe midhiya anoodza zvakanyanya tichishandisa marara asingadziviriri uye zvinhu zvemagetsi.
Chinwiwa:Kuyera zvigadzirwa, zvepakati uye zvakapedzwa zvigadzirwa panguva yekugadzirwa kwemukaka, muto, chinwiwa chinodhaka uye zvimwe zvinwiwa.
Metallurgy:Kuyera mineral slurry, tailing slurry, marasha slurry mvura mune ore kugadzirisa nezvinhu zvinopfekwa.
Energy:Kuyera kutenderera kwemvura inotonhorera, condensate, kemikari yekurapa zvinwiwa mumagadzirirwo emagetsi emagetsi, nezvimwe.
Shanghai Wangyuanine makore anopfuura makumi maviri echiitiko chekugadzira uye sevhisi yekuyera chiridzwa. Ruzivo rwedu rwakakura rwehunyanzvi uye zvidzidzo zvekesi munzvimbo dzese dzine marudzi ese emamita ekuyerera zvinoita kuti tipe kuyerera kwekutarisa mhinduro dzinosangana nezvido zvako chaizvo. Kana paine chero mibvunzo uye zvinodiwa nezve electromagnetic kuyerera mita, ndapota usazeza kusvika kwatiri.
