Udindo Wofunika Kwambiri wa Ma Electromagnetic Flowmeters Poyesa Madzi Oyendetsa Magesi

Kulondola Kosayerekezeka M'malo Oyendetsera Ntchito​

Pakati pa ntchito ya EMF pali mphamvu ya maginito yopangidwa mkati mwa chitoliro chosakhala cha maginito. Pamene madzi oyendetsera magetsi akuyenda m'munda uwu, amayambitsa magetsi ofanana ndi liwiro lake—lomwe limayesedwa ndi ma electrode omwe ali mu khoma la chitoliro. Kapangidwe kameneka kamachotsa kufunikira kwa magawo osuntha kapena zinthu zosokoneza, zomwe zingasokoneze kuyenda kapena kuchepa pakapita nthawi. Pa madzi oyendetsera magetsi okhala ndi mphamvu yotsika ngati 5 µS/cm (mlingo womwe umafikiridwa mosavuta ndi zakumwa zambiri zamafakitale, madzi otayira, komanso zakumwa zambiri), ma EMF amapereka kulondola kwapadera, nthawi zambiri mkati mwa ±0.5% ya mtengo woyesedwa.​

Taganizirani za malo oyeretsera madzi akuda a m'matauni: zimbudzi zosaphika, zokhala ndi zinthu zolimba zosungunuka ndi zinthu zachilengedwe, zimayendetsa bwino kwambiri. Makina oyeretsera madzi achikhalidwe amavutika chifukwa cha kutsekeka kapena kuwonongeka kwa tinthu tomwe timayabwa, zomwe zimapangitsa kuti zolakwika zikhale 5–10%. Mosiyana ndi zimenezi, ma EMF sakhudzidwabe. Kafukufuku wa 2023 wa Water Environment Federation adapeza kuti ma EMF omwe adayikidwa m'mizere ya madzi akuda amasunga kulondola mkati mwa ±0.3% kwa miyezi 12, ngakhale kuti kuchuluka kwa madzi ndi tinthu tating'onoting'ono kumasinthasintha. Kulondola kumeneku kumatsimikizira kuti malo oyeretsera madzi amatha kutsatira molondola kuchuluka kwa madzi omwe amalowa, kukonza kuchuluka kwa mankhwala, ndikupereka lipoti la deta yogwirizana ndi kudalirika.​

Kusinthasintha kwa Ma Conductive Fluids Osiyanasiyana​

Madzi otulutsa mpweya amakhala ndi mitundu yosiyanasiyana ya kukhuthala, kutentha, ndi mankhwala, kuyambira ma emulsions okhuthala a mafuta m'madzi mumakampani azakudya mpaka ma acid omwe amawononga chilengedwe pokonza mankhwala. Ma EMF amachita bwino kwambiri pamtunduwu. Kapangidwe kawo kosalowerera ndale kamalimbana ndi dzimbiri akaphatikizidwa ndi zinthu zogwirizana (monga ma PTFE liners a ma acid kapena ma electrode achitsulo chosapanga dzimbiri a ma caustic solutions), zomwe zimapangitsa kuti akhale oyenera madzi omwe angawononge makina oyezera.​

Mu gawo la migodi, matope—osakaniza madzi ndi tinthu ta mchere tomwe timayendetsa bwino mpweya—ndi chinthu chovuta kuyeza. Komabe, ma EMF amagwira matope okhala ndi zinthu zolimba mpaka 70% popanda kutayika kwa ntchito. Mgodi wa mkuwa ku Chile unanena kuti kusintha kwa ma EMF kunachepetsa kukonza kosakonzekera ndi 80% poyerekeza ndi ma paddlewheel mita, zomwe zimafuna kuyeretsa sabata iliyonse chifukwa cha kuchuluka kwa matope. Ma EMF adaperekanso deta yokhudzana ndi kayendedwe ka madzi nthawi yeniyeni, zomwe zimathandiza mgodi kusintha liwiro la pampu ndikuchepetsa kugwiritsa ntchito mphamvu ndi 12% pachaka.​

Kusinthasintha ndi Mikhalidwe Yoyenda Mosinthasintha​

Madzi oyendetsera mpweya nthawi zambiri amakhala ndi kuchuluka kwa madzi oyenda mosiyanasiyana, kuyambira kuthamanga kochepa mu ulimi wothirira mpaka kuyenda mwachangu kwambiri m'mapaipi a mafakitale. Ma EMF amasunga kulondola pa chiŵerengero chachikulu cha madzi oyenda—nthawi zambiri 100:1 (monga kuyeza madzi oyenda kuchokera pa 0.1 mpaka 10 m/s)—kupitirira chiŵerengero cha 10:1 cha mamita ambiri amakina. Kusinthasintha kumeneku ndikofunikira kwambiri pakugwiritsa ntchito monga kupanga pulp ndi mapepala, komwe ma pulp suspensions (oyendetsa madzi chifukwa cha kuchuluka kwa madzi) amakumana ndi kusinthasintha kwa madzi mofulumira panthawi yopanga.​

Kampani yopanga mapepala ku Finland inagwiritsa ntchito ma EMF kuti iwunikire kayendedwe ka madzi a pulp pamene akupanga bleach. Mamitawo anatsatira molondola kuchuluka kwa madzi pamene ankakwera kuchokera pa 2 m/s mpaka 8 m/s panthawi yogwira ntchito, kuonetsetsa kuti hydrogen peroxide imaperekedwa molondola. Izi zinachepetsa zinyalala za mankhwala ndi 15% ndipo zinapangitsa kuti mapepala akhale olimba, monga momwe zatsimikiziridwa ndi kusiyana kwa kuwala.​

Ubwino wa Zachilengedwe ndi Zachuma​

Kupatula kulondola ndi kusinthasintha, ma EMF amathandizira kukhazikika komanso kusunga ndalama. Kugwira ntchito kwawo kosunga mphamvu (komwe kumagwiritsa ntchito ma watts 10 okha) kumasiyana ndi makina oyezera mphamvu omwe amawononga mphamvu poletsa kuyenda kwa madzi. Mu fakitale yayikulu ya mankhwala ku Germany, kusintha makina oyezera magetsi ndi ma EMF mu payipi ya mainchesi 12 yokhala ndi chosungunulira chowongolera mpweya kunachepetsa ndalama zopopera mphamvu ndi pafupifupi €4,000 pachaka, malinga ndi kafukufuku wa 2024.​

Kuphatikiza apo, ma EMF amathandizira kuzindikira kutuluka kwa madzi m'maukonde oyendetsera madzi. Mwa kuyang'anira mosalekeza kusiyana kwa kayendedwe ka madzi pakati pa malo olowera ndi otuluka, ogwira ntchito amatha kuzindikira zolakwika zomwe zikuwonetsa kutuluka kwa madzi - zomwe ndizofunikira kwambiri popewa kuipitsidwa kwa chilengedwe. Kampani yoyeretsera mafuta ku Texas idagwiritsa ntchito ma EMF kuti izindikire kutuluka kwa madzi pang'ono mu payipi yamafuta osakonzedwa (yoyendetsedwa ndi mchere wosungunuka) isanakwere, kupewa ndalama zokwana $500,000 zoyeretsera komanso chindapusa cha malamulo.​

Mapeto​

Ma electromagnetic flowmeters asintha momwe madzi oyendetsera magetsi amayezedwera, zomwe zimapereka kulondola kosayerekezeka, kusinthasintha, komanso kudalirika m'malo omwe mita yachikhalidwe imalephera. Kuyambira kuyeretsa madzi otayira mpaka migodi ndi kukonza mankhwala, kuthekera kwawo kuthana ndi mavuto apadera a madzi oyendetsera magetsi—kusungunuka, dzimbiri, ndi kuyenda kosinthasintha—kuwapangitsa kukhala ofunikira kwambiri pantchito zamakono zamafakitale ndi m'mizinda. Pamene mafakitale akuika patsogolo magwiridwe antchito ndi kukhazikika, udindo wa EMFs pakuwonetsetsa kuti kuyeza madzi oyendetsera magetsi molondola, kotsika mtengo, komanso kotsatira malamulo kudzakula kwambiri.​
