Basa Rinokosha reElectromagnetic Flowmeters pakuyera maConductive Fluids

Kururama Kusingaenzaniswi Munzvimbo Dzinofambisa Mafambiro​

Pakati pekushanda kweEMF pane simba remagineti rinogadzirwa mukati mepombi isiri yemagineti. Kana mvura inoyerera ichipfuura nemumunda uyu, inokonzera voltage inoenderana nekumhanya kwayo—inoyerwa nemaelectrode akaiswa mumadziro epombi. Dhizaini iyi inobvisa kudiwa kwezvikamu zvinofamba kana zvinhu zvinopinda, izvo zvinogona kukanganisa kuyerera kana kuora nekufamba kwenguva. Kune mvura inoyerera ine conductivity yakaderera se5 µS/cm (muganho unosvikika nyore nyore nemafuta mazhinji emumaindasitiri, mvura yakasviba, uye kunyange zvinwiwa zvakawanda), maEMF anopa kururama kwakanyanya, kazhinji mukati me ±0.5% yemutengo wakayerwa.​

Funga nezvenzvimbo dzekuchenesa mvura yetsvina dzemumaguta: tsvina isina kucheneswa, ine zvinhu zvakanyungudutswa nezvinhu zvakasikwa, inofambisa mvura zvakanyanya. Michina yemazuva ano inonetsa pano nekuda kwekuvharika kana kupera kwezvimedu zvinokwenya, zvichikonzera zvikanganiso zvinosvika 5–10%. Kusiyana neizvi, maEMF haana kukanganiswa. Ongororo yakaitwa muna 2023 neWater Environment Federation yakawana kuti maEMF akaiswa mumitsetse yemvura yakasviba akaramba akarurama mukati me ±0.3% mukati memwedzi gumi nemiviri, kunyangwe paine kuchinja kwehuwandu hwemvura uye huwandu hwezvimedu. Kunyatsojeka uku kunoita kuti nzvimbo dzekurapa dzigone kutevedzera huwandu hwemvura inobuda, kugadzirisa huwandu hwemakemikari, uye kushuma data rekutevera nechivimbo.

Kuchinja-chinja kwemvura mumhando dzakasiyana-siyana dzinofambisa mvura​

Mvura inoyerera inotenderera ine mhando dzakasiyana-siyana dze viscosities, tembiricha, uye makemikari, kubva ku viscous oil-in-water emulsions muindasitiri yechikafu kusvika kune corrosive acid solutions mu chemical processing. EMFs dzinobudirira pane izvi. Dhizaini yadzo isingapindi inodzivirira ngura kana yakabatana nezvinhu zvinoenderana (semuenzaniso, PTFE liners ye acids kana stainless-steel electrodes ye caustic solutions), zvichiita kuti dzikodzere mvura inogona kuparadza mechanical meter.​

Muchikamu chemigodhi, slurry—musanganiswa wemvura nezvimedu zvemineral zvine conductivity yakakwira—mvura yakaoma kuyera. Zvisinei, maEMF anobata slurry ine zvinhu zvakasimba kusvika ku70% pasina kurasikirwa nekushanda. Mugodhi wemhangura muChile wakashuma kuti kuchinja kuenda kuEMF kwakaderedza kugadziriswa kusina kurongwa ne80% zvichienzaniswa nemapaddlewheel metres, izvo zvaida kucheneswa vhiki nevhiki nekuda kweslurry building. MaEMF akapawo data rekufamba kwenguva chaiyo, zvichiita kuti mugodhi ugadzirise kumhanya kwepombi uye kuderedza kushandiswa kwesimba ne12% pagore.​

Kuchinjika kuDynamic Flow Conditions​

Mvura inoyerera nemhepo inowanzo ratidza mwero wekuyerera kwakasiyana-siyana, kubva pakumhanya kwakaderera mukudiridza kwekurima kusvika pakuyerera nekukurumidza mumapaipi emaindasitiri. MaEMF anochengetedza kururama kwehuwandu hwemvura inoyerera nemhepo—kazhinji 100:1 (semuenzaniso, kuyera kuyerera kubva pa0.1 kusvika 10 m/s)—kupfuura chiyero che10:1 chemamita akawanda emakanika. Kuchinjika uku kwakakosha mukushandiswa senge kugadzira pulp nemapepa, uko pulp suspensions (inotungamira nekuda kwehuwandu hwemvura) inosangana nekuchinja-chinja kwekuyerera nekukurumidza panguva yekugadzira.​

Imwe kambani yekugadzira mapepa muFinland yakashandisa maEMFs kutarisa kuyerera kwemvura mukuita kwayo kuchena. Mamita aya ainyatsoongorora mwero wekuyerera kwemvura sezvaaikwira kubva pa2 m/s kusvika 8 m/s panguva yekushanda kwebatch, zvichiita kuti hydrogen peroxide iwanikwe nemazvo. Izvi zvakaderedza marara emakemikari ne15% uye zvakavandudza kugadzikana kwemhando yepepa, sezvakaratidzwa nekudzikira kwekuyera kwekupenya.​

Mabhenefiti Ezvakatipoteredza Nehupfumi​

Kupfuura kururama uye kushanduka-shanduka kwezvinhu, maEMF anobatsira mukuchengetedza simba uye kuchengetedza mari. Kushanda kwawo nenzira isingadyi simba zvakanyanya (kunoshandisa mawatts gumi chete) kunosiyana nemameta emakanika anokonzera kuderedzwa kwesimba, ayo anotambisa simba nekudzora kuyerera kwemvura. Mune imwe fekitori yakakura yemakemikari muGermany, kutsiva mameta emakanika nemaEMF mupaipi ye 12-inch inotakura conductive solvent kwakaderedza mari yesimba rekupomba neinenge €4,000 pagore, zvichienderana neongororo ya2024.​

Pamusoro pezvo, maEMF anorerutsa kuonekwa kwekudonha kwemvura muma network emvura inoyerera. Nekutarisa nguva dzose musiyano wekufamba kwemvura pakati penzvimbo dzinopinda nekubuda kwemvura, vashandi vanogona kuona zvisina kunaka zvinoratidza kudonha kwemvura—zvakakosha pakudzivirira kusvibiswa kwezvakatipoteredza. Imwe kambani yekuchenesa mafuta muTexas yakashandisa maEMF kuona kudonha kudiki mupombi yemafuta asina kucheneswa (inofambisa mvura nekuda kwemunyu wakanyungudutswa) isati yakwira, zvichidzivirira mari inofungidzirwa kuti inosvika $500,000 yekuchenesa uye faindi dzemutemo.​

Mhedziso​

Ma electromagnetic flowmeters akachinja maitiro ekuyera mvura dzinofambisa mvura, zvichipa kururama kusingaenzaniswi, kushanduka-shanduka, uye kuvimbika munzvimbo dzine mamita echinyakare anokundikana. Kubva pakugadzirisa mvura yakasviba kusvika pakuchera nekugadzira makemikari, kugona kwavo kugadzirisa matambudziko akasiyana emvura dzinofambisa mvura—kuora, ngura, uye kuyerera kwakasiyana-siyana—zvinoita kuti zvive zvakakosha pakushanda kwemaindasitiri nemakanzuru emazuva ano. Sezvo maindasitiri achinyanya kukoshesa kushanda zvakanaka uye kuchengetedzeka, basa reEMFs mukuona kuti kuyerwa kwemvura inofambisa mvura kwakarurama, kusingadhuri, uye kunoenderana nezvinodiwa kuchawedzera kukosha.​
