1. Chiyambi
1.1 Mbiri
Kutuluka kwa madzi otayira m'mafakitale kumawopseza kwambiri zachilengedwe ndi thanzi la anthu. Kuwunika kayendedwe ka madzi nthawi yeniyeni ndikofunikira kwambiri pakukonza njira zochizira ndikuwonetsetsa kuti malamulo azachilengedwe akutsatira, chifukwa deta yolondola ya kayendedwe ka madzi ingayambitse kugwiritsa ntchito mankhwala molakwika kapena kutaya madzi m'thupi mosayenera.
1.2 Cholinga cha Kafukufuku
Pepala ili likufotokoza momwe ma electromagnetic flowmeters (EMFs) amagwiritsidwira ntchito pochiza madzi akuda m'mafakitale, cholinga chake ndi kuwonetsa udindo wawo pakukweza magwiridwe antchito komanso kuteteza chilengedwe.
2. Mfundo Yogwirira Ntchito yaMa Electromagnetic Flowmeters
2.1 Lamulo la Faraday la Kuyambitsa Magetsi a Magetsi
Ma EMF amagwira ntchito motsatira lamulo la Faraday: pamene madzi otayira oyendetsedwa ndi mpweya akuyenda kudzera mu mphamvu ya maginito, amapanga mphamvu yamagetsi yoyendetsedwa ndi mpweya (EMF) yofanana ndi liwiro la madzi. EMF iyi imadziwika ndi ma electrode, ndipo kuchuluka kwa madzi kumawerengedwa pogwiritsa ntchito njira yopangira zizindikiro.
2.2 Zinthu Zaukadaulo
Zinthu zofunika kwambiri ndi monga kapangidwe kosalowerera (kopanda kutsekeka kwa madzi), kulondola kwambiri (± 0.5% ya sikelo yonse), kusiyanasiyana (1:100 turndown ratio), komanso kukana dzimbiri kuchokera ku madzi otayira acid/alkaline.
3. Zochitika Zogwiritsira Ntchito Pokonza Madzi Otayira mu Mafakitale
3.1 Kuwunika Kuyenda kwa Malo Olowera
Ma EMF amatsata kuchuluka kwa madzi omwe amalowa kuti apewe kuchuluka kwa matanki ochiritsira, kuonetsetsa kuti madzi oyambira ndi mayunitsi ochiritsira akugwiritsidwa ntchito nthawi zonse.
3.2 Kulamulira Mlingo wa Mankhwala
Pogwirizana ndi machitidwe a PLC, ma EMF amakonza mlingo wa coagulant/flocculant kutengera kuyenda kwa madzi nthawi yeniyeni, kuchepetsa zinyalala za mankhwala ndi 15-20% poyerekeza ndi mlingo wokhazikika.
3.3 Kuwunika Kuyenda kwa Madzi Otayirira
Amayesa kubwerera kwa matope ndi kutuluka kwa madzi otayidwa, kukulitsa mphamvu ya kugaya chakudya popanda mpweya komanso kuchepetsa ndalama zogwiritsira ntchito matope ochulukirapo.
4. Kuphatikiza Machitidwe ndi Kuyang'anira Deta
4.1 Kapangidwe ka Zida
Ma EMF amalumikizana ndi ma transmitter, ma pH sensor, ndi ma DCS system. Amayang'ana kwambiri zinthu zama electrode (monga Hastelloy yamadzimadzi okhwima) komanso kugwirizanitsa kukula kwa mapaipi.
4.2 Kuwongolera Mapulogalamu ndi Kusanthula Deta
Mapulogalamu oyambira amalola kuwona momwe zinthu zilili nthawi yeniyeni komanso kuyambitsa ma alarm kuti pakhale kuchuluka kwa zinthu zosayembekezereka. Kulemba deta mosavuta kumathandiza kuwunika momwe zinthu zilili mlungu uliwonse.
5. Ubwino ndi Kufunika
5.1 Ubwino waukadaulo
Mosiyana ndi ma flowmeter a turbine,Ma EMFsizimakhudzidwa ndi kukhuthala kwa madzi kapena zinthu zolimba zomwe zimapachikidwa, zomwe zimachepetsa kuchuluka kwa kukonza.
5.2 Ubwino wa Zachilengedwe ndi Zachuma
Amaonetsetsa kuti madzi otayira akukwaniritsa malire otulutsira madzi, kupewa chindapusa. Mwa kugwiritsa ntchito bwino mankhwala ndi mphamvu zomwe zimagwiritsidwa ntchito, ndalama zogwirira ntchito zimachepetsedwa ndi 10-15%.
6. Mavuto ndi Zochitika Zamtsogolo
6.1 Mavuto Amene Alipo
Kuipitsa ma elekitirodi ndi zinthu zachilengedwe kumafuna kutsukidwa nthawi ndi nthawi. Kuyika zinthu mokwera mtengo kungalepheretse malo ang'onoang'ono.
6.2 Zochitika Zamtsogolo
Kuphatikizana ndi IoT kudzathandiza kuyang'anira kutali ndi kukonza zinthu moganizira. Kupanga ma EMF otsika mtengo komanso ang'onoang'ono kudzakulitsa kugwiritsa ntchito kwawo.
7. Mapeto
Ma EMF ndi ofunikira kwambiri pakuwunika nthawi yeniyeni pakukonza madzi otayidwa m'mafakitale, zomwe zimapereka ubwino waukadaulo, chilengedwe, komanso zachuma. Kuthana ndi mavuto omwe alipo komanso kugwiritsa ntchito ukadaulo wanzeru kudzawonjezera ntchito yawo pakusamalira madzi mokhazikika.
