An mita yekuyerera kwemagetsi(inozivikanwawo se magnetic flow meter kana mag meter) ndeimwe yezvishandiso zvakanyatsonaka zvekuyera kuyerera kwemvura inofambisa mvura. Nekuda kwekugadzirwa kwayo kwezvikamu zvisingafambi, electromagnetic flow meter inopa kugadzikana kwakanaka kwenguva refu, kuchengetedza kushoma, uye kunyatsoyera kwakakodzera.
Zvisinei, kunyangwe muchina wemagetsi wakaiswa zvakanaka unogona dzimwe nguva kusangana nekuyerera kwemvura kana kuverenga kusina kugadzikana mushure memakore ekushanda. Kana izvi zvikaitika, vashandisi vanowanzo fungidzira kuti muchina wemagetsi pachawo, asi kazhinji dambudziko rinokonzerwa nemamiriro ekuisa, shanduko dzemaitiro, kana kugadziriswa kwete kutadza kushanda kwemidziyo.
Kunzwisisa zvikonzero zvinowanzokonzera kuyerera kwemagetsi (electromagnetic flow meter drift) ndiyo nhanho yekutanga yekudzoreredza kuyerwa kwekuyerera kwakarurama uye kwakavimbika.
1. Kusvibisa Maerekitirodhi Kunoderedza Kururama Kwekuyera
Electrode ye electromagnetic flow meter ine basa rekuona voltage diki inogadzirwa kana mvura inoyerera ichipfuura nemumunda wemagineti. Nekufamba kwenguva, zvinhu zvinogona kuungana pamusoro pe electrode, zvichikanganisa kunaka kwechiratidzo uye zvichikonzera kuyerera zvishoma nezvishoma kwekuyerwa.
Mari dzinowanikwa dzinosanganisira:
Chikero checalcium
Ngura
Mafuta nemafuta
Makemikari akaiswa mumiti
Kusvibisa kwezvipenyu
Sezvo kusvibiswa kuchiwedzera, kurongeka kwemuchina wemagetsi unoyerera kunogona kudzikira zvishoma nezvishoma, kunyanya mumvura yakasviba uye mumaindasitiri.
Mhinduro inokurudzirwa
Ongorora uye chenesa maerekitirodhi nguva dzose.
Sarudza zvinhu zve electrode zvinoenderana nemvura yakayerwa.
Rongai kuchengetedza mvura yakasviba kana masisitimu etsvina kudzivirira njodzi.
2. Kufamba Kwemhepo Kwakaderera kana Kuchinja
Kusiyana nedzimwe mhando dzema flow meter, electromagnetic flow meter inoshanda chete ne electrically conductive liquids. Kana liquid conductivity ikachinja zvakanyanya, induced signal inova isina simba, zvichikonzera kusagadzikana kwekuyerwa.
Zvikonzero zvinowanzo sanganisira:
Kuchinja kwehunhu hwemvura
Kusiyana kwehuwandu hwemakemikari
Kutsiva mvura yemuitiro
Kusanganisa nemvura yakacheneswa kana kuti isina ion
Kuyerera kwemuchina wemagetsi wakasimba kwakakosha pakuchengetedza zviyero zvakarurama.
Mhinduro inokurudzirwa
Iva nechokwadi chekuti mvura inoyerera inosangana nezvinodiwa nemugadziri.
Tarisa mafambiro emhepo kana mamiriro ekushanda achichinja.
3. Kupindirana kweMagetsi (EMI)
Ruzha rwemagetsi ndechimwe chezvikonzero zvakajairika zvekugadzirisa matambudziko emagetsi anoyerera.
Midziyo iri pedyo yakaita se:
Madhiraivha Anochinja-chinja (VFDs)
Mota dzemagetsi hombe
Michina yekuwedera
Tambo dzemagetsi ane simba guru
Matransformer
zvinogona kukonzera kukanganiswa kwemagetsi kunokanganisa chiratidzo che sensor, zvichikonzera kuverenga kwemvura isina kugadzikana kana kuyerera kwemvura kuri pachena.
Mhinduro inokurudzirwa
Iva nechokwadi chekuti pasi rakakodzera.
Shandisa tambo dzechiratidzo dzakadzivirirwa.
Bvisa tambo dzemagetsi kubva kune dzekutaurirana.
Isa chinotumira mashoko kure neminda ine simba remagetsi.
4. Kuisa Zvisina Kufanira kana Mapaipi Akazadzwa Zvishoma
Kuisa mita yekuyerera kwemagetsi nemazvo kwakakosha kuti kuyera kurambe kwakarurama.
Chiyero chemagetsi chinoyera mvura chinoda kuti chubhu yekuyera igare yakazara nemvura. Mafuro emhepo kana mapaipi akazadzwa zvishoma anoderedza kusangana kweelectrode nemvura inofambisa mvura, zvichikonzera kuverenga kusina kugadzikana.
Matambudziko akajairika ekuisa anosanganisira:
Pombi haina kuzara zvachose
Homwe dzemhepo
Kuiswa panzvimbo yakakwirira yepombi
Kuyerera kwemvura pasi pasina kumanikidzwa kwakakwana kwemusana
Mamiriro aya anowanzo kukonzera kuverenga kwemvura kusina kugadzikana pane kutadza kwemita chaiyo.
Mhinduro inokurudzirwa
Isa mita iyo paipi inogara yakazara.
Sarudza kuyerera kwakamira kumusoro kana zvichibvira.
Bvisa mweya wakavharirwa kubva muhurongwa.
Tevedzera zvinodiwa nemapaipi akatwasuka anokurudzirwa.
5. Kusadzika zvakanaka kwevhu
Kuisa pasi kwakakodzera ndechimwe chezvinhu zvisinganyanyi kutariswa pakuiswa kwe electromagnetic flow meter.
Pasina kudzika zvakanaka, ruzha rwemagetsi runogona kupinda mudunhu rekuyera, zvichikonzera:
Kuyerera kwekuyera kuyerera
Kusagadzikana kwe zero-point
Kuchinja-chinja kwezviratidzo
Kunyatsojeka kwekuyera
Mapaipi epurasitiki kana rabha anowanzoda maring ekudzika nekuti pombi pachayo haigone kupa referensi yemagetsi.
Mhinduro inokurudzirwa
Isa ma grounding rings kana zvichidikanwa.
Tarisa kuramba kwepasi panguva yekuisa simba.
Tevedzera mirairo yemugadziri wepasi.
6. Kuona Pombi Isina Chinhu uye Kuchinja Maitiro
Mazhinji ema magnetic flow meter emazuva ano ane basa rekuona pombi isina chinhu kudzivirira kuyerwa kwenhema.
Kana pombi isina kuzadzwa zvakakwana nekuda kwekutenderera kwepombi, kuvharwa kwepombi, kana kushanda kwenguva pfupi, flow meter inogona kuchinja kakawanda pakati pekuyera kwakajairika nemamiriro epombi isina chinhu.
Izvi zvinogona kuonekwa sekuverenga kusina kugadzikana kana kuyerera kwemvura kunooneka.
Mhinduro inokurudzirwa
Iva nechokwadi chekuti pombi yakazara inogara iripo.
Tarisa mashandiro epombi.
Iva nechokwadi chekuti marongero ekuona pombi isina chinhu akagadzirwa nemazvo.
7. Kukwegura kweSensor uye Zvemagetsi
Kunyange zvazvo ma "electromagnetic flow meter" emazuva ano eindasitiri achivimbika zvikuru, kushanda kwenguva refu mumamiriro ezvinhu akaoma kunogona kukanganisa zvishoma nezvishoma zvikamu zvemagetsi.
Zvinhu zvinogona kuitika zvinosanganisira:
Tembiricha yepamusoro yemhepo
Kupinda kwehunyoro
Kusagadzikana kwemagetsi
Kukwegura kwezvikamu
Kunyange zvazvo izvi zvisingawanzoitiki pane matambudziko ane chekuita nekuisa, zvinogona kukonzera kushaikwa kwenguva refu kwekuyera.
Mhinduro inokurudzirwa
Ongorora chinotumira mashoko nguva nenguva.
Chengetedza zvigadzirwa zvemagetsi mukati menzvimbo yazvo yekushanda yakatarwa.
Tsiva mamodule emagetsi akakuvara kana zvichidikanwa.
8. Kuenzanisa Kwemamita Emagetsi Asina Kururama
Kuongororwa kwemagetsi asingashande zvakanaka kunogona kukonzera kuti pave nechiyero chinogara chichiyerwa.
Kana pasina kuenzaniswa kwemvura ichiri kufamba nepaipi, mudziyo unogona kuramba uchiratidza kukosha kusina kunaka panguva yekushanda.
Mhinduro inokurudzirwa
Ita zero calibration chete kana pasina kuyerera zvachose.
Iva nechokwadi chekuti pombi yacho inoramba yakazara panguva yekuongororwa.
Tevedzera maitiro ekugadzirisa zvinhu emugadziri.
Maitiro Akanakisisa Ekuchengetedza Kururama Kwemamita Emagetsi
Kuti uwane kunyatsoyera kuyerera kwepamusoro-soro, tevera mazano aya ekugadzirisa:
Chenesa maerekitirodhi nguva dzose.
Chengeta pombi yakazara zvizere.
Chengetedza pasi uye dziviriro yakakodzera.
Dzivirira kukanganiswa kwemagetsi.
Tarisa kuti mvura inoyerera sei.
Tevedzera nhungamiro dzakakodzera dzekuisa.
Ita calibration nguva nenguva.
Tarisa shanduko dzemaitiro dzinogona kukanganisa kugadzikana kwekuyera.
Kugadziriswa nguva dzose hakungobatsiri chete pakugadzirisa mafambiro emagetsi asi kunowedzerawo hupenyu hwechishandiso uye kunoderedza nguva isingatarisirwi yekushanda.
Kuyerera kwekuyerera kwemvura mu electromagnetic flow meter kunowanzo kukonzerwa nemamiriro ekuisa, kushanduka kwemaitiro, kukanganiswa kwemagetsi, kana kusagadziriswa kwakakwana—kwete ne flow meter pachayo.
Nekutevera kuisirwa kwema electromagnetic flow meter nemazvo, kuchengetedza ma electrodes akachena, kuona kuti electrodes dzinofambisa mvura zvakakwana, kuita calibration yenguva dzose yema electromagnetic flow meter, uye kubvisa kupindirana kwemagetsi, vashandisi vanogona kuvandudza zvakanyanya kuyera kuyerera kwenguva refu uye kuchengetedza mag flow meter yavo ichishanda zvakanaka.
