Pamichina yemagetsi yemagetsi yeindasitiri, musimboti wekuyera flowmeter yemagetsi imutemo waFaraday we electromagnetic induction. Maumbirwo e electromagnetic flowmeter anonyanya kuumbwa ne magnetic circuit system, measuring conduit, electrode, shell, lining uye converter. Inonyanya kushandiswa kuyera huwandu hwemhepo inofambisa mvura uye slurry mumapaipi akavharwa. Kusanganisira acids, alkalis, munyu nezvimwe zvinopisa zvakanyanya. Chigadzirwa ichi chinoshandiswa zvakanyanya mu petroleum, chemicals, metallurgy, textile, food, pharmaceutical, papermaking nedzimwe nzvimbo, pamwe nekuchengetedzwa kwezvakatipoteredza, manejimendi yemaguta, kuvaka kwekuchengetedza mvura nedzimwe nzvimbo.
Mukushandisa electromagnetic flowmeter, zvimwe zvinhu zvinokundikana mukushandisa zvinozoitika. Kazhinji pane mhando mbiri dzekutadza kushanda: imwe ndeyekutadza kwechinhu chacho pachacho, kureva kuti, kutadza kunokonzerwa nekukuvara kwezvikamu zvechimiro kana zvikamu zvechinhu chacho; yechipiri, kutadza kunokonzerwa nezvikonzero zvekunze, zvakaita sekuiswa zvisina kunaka, kukanganiswa kwemvura, kuiswa kwemvura uye kukura kwechinhu, nezvimwewo.
Kana electromagnetic flowmeter ikakundikana, tinowanzo fanirwa kuongorora kuti ndechipi chikamu chiri kukanganisa tobva tawana kuti tingagadzirisa sei dambudziko racho.
1. Zvikanganiso zvinowanzoitwa ne electromagnetic flowmeter - electromagnetic flowmeter haina flow signal output
Rudzi urwu rwekukundikana runowanzoitika panguva yekushandisa, uye zvikonzero zvinowanzo kuve:
(1) Simba remuchina wacho harina kujairika;
(2) Kubatana kwetambo uye kubuda kwebhodhi remagetsi hazvina kujairika;
(3) Kuyerera kwemvura hakusviki pazvinodiwa pakuiswa;
(4) Zvikamu zve sensor zvakuvara kana kuti pane jira rinonamira pamadziro emukati mechiyero;
(5) Zvikamu zvechishanduri chakakuvara
Nzira yekugadzirisa sei?
Kana izvi zvikaitika, tanga watarisa kana simba remuchina wacho risina kunaka, simbisa kuti simba remuchina rakabatana, tarisa kana voltage inobuda yebhodhi redunhu remagetsi iri yakajairika, kana edza kutsiva bhodhi rese redunhu remagetsi kuti uone kana rakanaka. Tarisa kuti tambo dzacho dzakanyatsopinda uye dzakabatana nemazvo. Tarisa kuti mvura iri mupombi yazara here uye mvura iri mupombi yazara. Kana pasina mvura iri musensor, uchafanira kutsiva chubhu kana kuchinja nzira yekuisa. Edza kuiisa yakatwasuka.
2. Chiratidzo che electromagnetic flowmeter chiri kuramba chichiderera kana kuti chiratidzo chinongoerekana chadonha
Zvizhinji zvezvikanganiso izvi zvinokonzerwa nekukanganiswa kwenzvimbo yekuyera kana nharaunda yekunze, uye kukanganisa kunogona kubviswa kwega mushure mekunge kupindira kwekunze kwabviswa. Kuti kuve nechokwadi chekuti chiyero chakarurama, zvikanganiso zvakadaro hazvigone kufuratirwa. Mune dzimwe nzvimbo dzekugadzira, nekuda kwekuzunguzika kukuru kwepombi yekuyera kana mvura, bhodhi redunhu re flowmeter richasunungurwa, uye kukosha kwekubuda kunogonawo kuchinja.
Nzira yekugadzirisa sei?
(1) Simbisa kana chiri chikonzero chekushanda kwemaitiro acho, uye mvura yacho ichirova. Panguva ino, flowmeter inoratidza chete mamiriro ekuyerera kwemvura, uye dambudziko rinogona kubviswa roga mushure mekunge pulsation yapera.
(2) Kukanganiswa kwemagetsi kunokonzerwa nemagetsi anodonha kubva kunze, nezvimwewo. Tarisa kana paine midziyo yemagetsi mikuru kana michina yemagetsi yekuwedera iri kushanda munzvimbo yekushanda yemudziyo, uye iva nechokwadi chekuti mudziyo wacho wakadzika uye nzvimbo yekushanda yakanaka.
(3) Kana pombi isina kuzadzwa nemvura kana kuti mvura yacho iine mabubble emhepo, zvese zvinokonzerwa nezvikonzero zvekushanda kwayo. Panguva ino, nyanzvi inogona kukumbirwa kuti isimbise kuti huwandu hwemvura inobuda hunogona kudzokera pahunhu hwakanaka mushure mekunge mvura yazara kana kuti mabubble emhepo adzikamiswa.
(4) Bhodhi redunhu remuchina wekutumira zvinhu rakaita se plug-in. Nekuda kwekudengenyeka kukuru kwepombi yekuyera iri panzvimbo yacho kana mvura, bhodhi remagetsi remuchina wekufambisa zvinhu rinowanzo sunungurwa. Kana rakasununguka, muchina wekufambisa zvinhu unogona kuparadzaniswa uye bhodhi redunhu rinogona kugadziriswazve.
3. Nzvimbo ye zero ye electromagnetic flowmeter haina kugadzikana
Kuongorora Chikonzero
(1) Paipi haina kuzadzwa nemvura kana kuti mvura yacho ine mabubble emhepo.
(2) Zvichienderana nepfungwa, zvinofungidzirwa kuti hapana kuyerera kwemvura mupombi yechubhu, asi pane kuyerera kudiki.
(3) Zvikonzero zvemvura (zvakadai sekusafanana kwemvura inoyerera, kusvibiswa kwema electrode, nezvimwewo).
(4) Kudzivirira kwedunhu rechiratidzo kunoderedzwa.
Nzira yekugadzirisa sei?
Zvakakosha kutarisa kana nzvimbo yacho yakazara nemapombi uye kana paine mabubble emhepo mukati menzvimbo yacho. Kana paine mabubble emhepo, mudziyo unobvisa mhepo unogona kuiswa kumusoro kwemabubble emhepo. Kuiswa kwemudziyo kwakatwasuka kunogonawo kuchinjwa kuti kuiswe kwakatwasuka. Tarisa kana mudziyo wacho wakadzika zvakanaka. Kudzivirira kwepasi kunofanira kunge kuri pasi kana kuti kwakaenzana ne100Ω; kufambisa kwenzvimbo yacho hakufanirwe kunge kuri pasi pe5μs/cm. Kana nzvimbo yacho ikaungana muchubhu yekuyera, inofanira kubviswa nenguva. Dzivisa kukwenya jira panguva yekubvisa.
