Mafambiro uye Kuvandudzwa muTekinoroji yeElectromagnetic Flow Meter

Ma electromagnetic flow meter anga ari chinhu chikuru mumaindasitiri anoda kuyerwa kwakarurama kwe conductive fluid flow. Achishanda pasi pemutemo waFaraday we electromagnetic induction, anogadzira voltage inoenderana nekumhanya kwe conductive fluid inoyerera kuburikidza ne magnetic field. Sezvo tekinoroji ichiramba ichichinja nekukurumidza, electromagnetic flow meter landscape iri kuonawo shanduko huru. Kufambira mberi uku hakungowedzere kushanda nema meter aya chete asiwo kunovhura mashandisirwo matsva muzvikamu zvakasiyana-siyana.

Ma electromagnetic flow metres emazuva ano ane masensa anonzwa zvakanyanya. Matekiniki ekugadzira nemazvo anoita kuti zvikamu zvemukati, zvakaita sema electrodes nema magnetic coils, zvigadzirwe nemazvo. Semuenzaniso, vamwe vagadziri vari kushandisa michina yemhando yepamusoro yekugadzira ma electrodes ane magumo akapfava pamusoro. Izvi zvinoderedza kukanganisa kwe electrode polarization uye fouling, matambudziko akajairika mumagadzirirwo echinyakare. Nzvimbo yakapfava ye electrode inoderedza kuumbwa kwe biofilms kana deposits pakuyera mvura mukushandiswa senge kuchenesa mvura yakasviba kana kugadzirwa kwechikafu nezvinwiwa. Nekuda kweizvozvo, mita dzinogona kuchengetedza zviyero zvakarurama kwenguva yakareba pasina kuyera kana kugadzirisa nguva nenguva.

Maalgorithm ekugadzirisa masaini ave kunyanya kuomarara. Matekiniki edhijitari ekugadzirisa masaini (DSP) ikozvino anoshandiswa zvakanyanya kuchenesa ruzha nekupindira. Munzvimbo dzemaindasitiri, ma electromagnetic flow meter anowanzo sangana neruzha rwemagetsi kubva kumamota, ma transformer, nemimwe michina. Ma algorithm matsva anogona kuona nekubvisa ruzha urwu rusingadiwe, zvichivandudza chiyero chechiratidzo - kune - ruzha. Semuenzaniso, ma algorithms ekugadzirisa anochinjika anogona kugadzirisa munguva chaiyo kune maitiro eruzha anochinja. Izvi zvinobvumira mita kuyera nemazvo voltage inokonzerwa, kunyangwe paine kusagadzikana kukuru kwemagetsi. Dzimwe nzira dzepamusoro dzekugadzirisa masaini dzinogonesawo mita kugadzirisa ma profiles ekuyerera asina kufanana, zvichiwedzera kurongeka kwekuyera.

Maitiro ekuita kuti zvinhu zvidiki zvishande zviri nyore anokonzerwa nekuda kwekushandisa michina midiki uye inoshanda zvakanaka, kunyanya mumabasa apo nzvimbo iri pamutengo wakaderera. Mamita madiki emagetsi ekuyerera kwemagetsi ava kuwanikwa pamapombi madiki se 0.5 inches. Midziyo iyi midiki yakazara nehunyanzvi hwakasiyana-siyana, kusanganisira kubatana kwekutaurirana kwedhijitari, sarudzo dzakawanda dzekuburitsa senge 4 - 20 mA, pulse, uye switch outputs. Dzakanakira kushandiswa mu process skids, laboratory setups, kana kure monitoring applications uko mita dzechinyakare dzakakura dzingave dzisingashande. Pasinei nehukuru hwadzo hudiki, dzinochengetedza kuyera kwakarurama, zvichiita kuti dzikodzere kushandiswa kunoda kuyerwa kwemvura kwakanyatsojeka muchikamu chidiki.

Kuti vasangane nezvinodiwa nemaindasitiri akasiyana-siyana, vagadziri vemagetsi vanoyera mafungu emagetsi vari kushandisa zvinhu zvakasiyana-siyana zvehunyanzvi. Mukushandiswa kunosanganisira mvura inoparadza zvakanyanya, senge muindasitiri yemakemikari, zvinhu zvakaita seHastelloy C, Tantalum, uye PTFE - zvakagadzirwa netambo zviri kushandiswa. Zvinhu izvi zvinodzivirira ngura zvakanaka, zvichiita kuti flow meter igare kwenguva refu. Semuenzaniso, mufekitori yekugadzira sulfuric acid, flow meter ine chubhu yekuyera ine Tantalum - yakagadzirwa netambo uye maelectrode eHastelloy C anogona kutsungirira mamiriro emakemikari akaoma pasina kuora. Izvi hazvingowedzere hupenyu hwemita chete asi zvinoderedzawo kudiwa kwekutsiva nguva nenguva, zvichikonzera kuchengetedza mari nekufamba kwenguva.

Kubatanidzwa kwema electromagnetic flow metres neInternet of Things (IoT) kuri kuchinja nzira yaanoshandiswa nayo mumaindasitiri. Ma flow metres anogoneswa neIoT anogona kuramba achitumira data renguva chaiyo pamusoro pehuwandu hwekuyerera kwemvura, tembiricha, nezvimwe zvakakosha kune system yekutarisa yepakati. Izvi zvinobvumira kutarisa nekudzora kuri kure, zvichigonesa vashandi kuita sarudzo dzakarongeka nenguva. Mune network yekugovera mvura, semuenzaniso, ma electromagnetic flow metres akabatana neIoT anogona kuona kubuda kwemvura kana mapatani ekuyerera asina kujairika nekukasika. Data rinogona kuongororwa kuti rifanotaura zvinodiwa pakugadzirisa, kugadzirisa kugoverwa kwemvura, uye kuderedza kurasikirwa kwemvura. Iyi nhanho yekubatana inogonesawo kubatanidzwa kusina musono nezvimwe zvishandiso zvakangwara uye masisitimu muindasitiri.

Ma electromagnetic flow meter emazuva ano ane kugona kuzviongorora. Anogona kugara achitarisa mashandiro awo, achitarisa matambudziko akadai sekuora kwema electrode, kusarongeka kwesimba remagineti, kana matambudziko ekutaurirana. Kuburikidza nekuongorora ma parameter emukati, aya mamita anogona kufanotaura kutadza kunogona kuitika asati aitika. Semuenzaniso, kana mita ikaona kuwedzera zvishoma nezvishoma mukusagadzikana kwe electrode, inogona kuzivisa vashandi vekugadzirisa, ichivabvumira kutsiva electrode nekukurumidza. Maitiro aya ekugadzirisa ekufanotaura anoderedza nguva yekusashanda yakarongwa, iyo inokosha mumaindasitiri uko kushanda nguva dzose kwakakosha, senge kugadzira magetsi kana kugadzirwa kwemafuta negasi.

Nzira itsva dzekuwedzera simba, dzakadai sekuwedzera simba remagetsi maviri (dual-frequency excitation) uye programmable master excitation, dziri kugadzirwa kuti dzivandudze kururama kwema electromagnetic flow metres. Idzi nzira dzekuwedzera simba dzinoderedza simba rezvinhu zvakaita se low-frequency electrochemical noise, kunyanya pakuyera kuyerera kwe solid-liquid two-phase slurries. Nekuda kweizvozvo, ma electromagnetic flow metres emazuva ano anogona kuwana kururamisa kwekuyera kwe ±0.5% kana kunyange ±0.2% indication error, zvichienzaniswa nemamodheru ekare. Pamusoro pezvo, kugona kweaya ma meter kwakawedzerwa. Iye zvino anogona kuyera nekunyatsojeka huwandu hwakakura hwekuyerera kwesimba, kubva pakuyerera kwakaderera kusvika pakuyerera kwesimba rakawanda, pasina kukanganisa kururama. Izvi zvinoita kuti zvive nyore kushandisa uye zvakakodzera kushandiswa kwakasiyana-siyana.

Tekinoroji yemagetsi inoyerera nemagetsi iri kuona shanduko inoshamisa. Kubva pakufambira mberi mukugadzira masensa uye kugadzirisa masaini kusvika pakubatanidzwa kwezvinhu zvakangwara uye zvakabatana, izvi zvitsva zviri kuwedzera mashandiro, kuvimbika, uye kushanduka-shanduka kwema electromagnetic flow metres. Maitiro ekuita kuti electromagnetic flow meters ave mashoma uye kushandiswa kwezvinhu zvakakosha kuri kuwedzera chiyero chavo chekushandisa, nepo kuvandudzwa kwekururama uye kugona kutenderera kuri kuita kuti zvive zvishandiso zvekuyera zvakanyatsojeka. Sezvo maindasitiri achiramba achida mazinga akakwira ekushanda, otomatiki, uye sarudzo dzinotungamirirwa nedata, tekinoroji yemagetsi inoyerera nemagetsi ichaita basa rakakosha mukuzadzisa zvinodiwa izvi. Remangwana rine vimbiso yakawanda, nekufambira mberi kunotarisirwa munzvimbo dzakadai sekuongorora kweruzivo rwemagetsi neruzivo rwemagetsi nekubatanidza matekinoroji ekukurukurirana akanyanya kufambira mberi.
