Zochitika ndi Zatsopano mu Ukadaulo wa Ma Electromagnetic Flow Meter

Ma electromagnetic flow meter akhala chinthu chofunikira kwambiri m'mafakitale omwe amafuna kuyeza molondola kayendedwe ka madzi oyendetsera magetsi. Pogwira ntchito motsatira lamulo la Faraday loyambitsa magetsi, amapanga magetsi ofanana ndi liwiro la madzi oyendetsera magetsi omwe akuyenda kudzera mu mphamvu ya maginito. Pamene ukadaulo ukupitirira kukula mofulumira, mawonekedwe a electromagnetic flow meter akuwonanso kusintha kwakukulu. Kupita patsogolo kumeneku sikungowonjezera magwiridwe antchito ndi magwiridwe antchito a mamitawa komanso kumatsegula ntchito zatsopano m'magawo osiyanasiyana.

Ma electromagnetic flow meter amakono ali ndi masensa ozindikira kwambiri. Njira zopangira molondola zimaonetsetsa kuti zigawo zamkati, monga ma electrode ndi maginito, zimapangidwa molondola kwambiri. Mwachitsanzo, opanga ena akugwiritsa ntchito njira zamakono zopangira ma electrode kuti apange ma electrode okhala ndi mawonekedwe osalala pamwamba. Izi zimachepetsa mphamvu ya electrode polarization ndi fouling, mavuto omwe amapezeka nthawi zambiri m'mapangidwe achikhalidwe. Malo osalala a electrode amachepetsa kupangika kwa biofilms kapena ma deposits poyesa madzi mu ntchito monga kukonza madzi otayira kapena kupanga chakudya ndi zakumwa. Zotsatira zake, ma meter amatha kusunga miyeso yolondola kwa nthawi yayitali popanda kukonza kapena kukonza pafupipafupi.

Ma algorithm ogwiritsira ntchito zizindikiro akhala ovuta kwambiri. Njira zogwiritsira ntchito zizindikiro za digito (DSP) tsopano zikugwiritsidwa ntchito kwambiri kuti zichotse phokoso ndi kusokoneza. M'malo opangira mafakitale, ma electromagnetic flow meter nthawi zambiri amakumana ndi phokoso lamagetsi kuchokera ku ma mota, ma transformer, ndi zida zina. Ma algorithm atsopano amatha kuzindikira ndikuchotsa phokoso losafunikira ili, ndikukweza chiŵerengero cha phokoso pakati pa chizindikiro ndi - phokoso. Mwachitsanzo, ma algorithm osinthira amatha kusintha nthawi yeniyeni kuti agwirizane ndi kusintha kwa phokoso. Izi zimathandiza kuti mita iziyeze molondola mphamvu yamagetsi yomwe yayambitsidwa, ngakhale pakakhala kusokonezeka kwakukulu kwamagetsi. Njira zina zapamwamba zogwiritsira ntchito zizindikiro zimathandizanso mita kukonza ma profiles oyenda omwe sali ofanana, zomwe zimawonjezera kulondola kwa muyeso.

Chizolowezi cha miniaturization chikuyendetsedwa ndi kufunika kwa zida zazing'ono komanso zogwira mtima, makamaka m'magwiritsidwe ntchito komwe malo ndi apamwamba kwambiri. Ma electromagnetic flow mita ang'onoang'ono tsopano akupezeka pamapaipi ang'onoang'ono ngati mainchesi 0.5. Zipangizo zazing'onozi zili ndi zinthu zambiri zosiyanasiyana, kuphatikizapo kulumikizana kwa digito, njira zingapo zotulutsira monga 4 - 20 mA, pulse, ndi switch outputs. Ndi abwino kugwiritsa ntchito pokonza ma process skids, ma laboratory setups, kapena ma remote monitoring applications komwe ma custom greater meters sangakhale othandiza. Ngakhale kuti ndi ang'onoang'ono, amasunga kulondola kwakukulu kwa muyeso, zomwe zimapangitsa kuti akhale oyenera kugwiritsa ntchito omwe amafunikira muyeso wolondola wamadzimadzi mu footprint yaying'ono.

Kuti akwaniritse zosowa za mafakitale osiyanasiyana, opanga ma electromagnetic flow meter akugwiritsa ntchito zipangizo zosiyanasiyana zapadera. Mu ntchito zokhudzana ndi madzi owononga kwambiri, monga makampani opanga mankhwala, zipangizo monga Hastelloy C, Tantalum, ndi PTFE - zomwe zili ndi mzere zikugwiritsidwa ntchito. Zipangizozi zimapereka kukana bwino kwambiri ku dzimbiri, zomwe zimaonetsetsa kuti flow meter imakhala yolimba kwa nthawi yayitali. Mwachitsanzo, mu fakitale yopanga sulfuric acid, flow meter yokhala ndi chubu choyezera cha Tantalum - ndi ma electrode a Hastelloy C imatha kupirira chilengedwe choopsa cha mankhwala popanda kuwonongeka. Izi sizimangowonjezera nthawi ya meter komanso zimachepetsa kufunika kosintha nthawi zambiri, zomwe zimapangitsa kuti ndalama zisungidwe pakapita nthawi.

Kuphatikizika kwa ma electromagnetic flow meter ndi Internet of Things (IoT) kukusintha momwe amagwiritsidwira ntchito m'mafakitale. Ma flow meter oyendetsedwa ndi IoT amatha kutumiza deta yeniyeni nthawi zonse pa kuchuluka kwa madzi, kutentha, ndi zina zofunika ku dongosolo loyang'anira pakati. Izi zimathandiza kuyang'anira ndi kuwongolera patali, zomwe zimathandiza ogwira ntchito kupanga zisankho zodziwikiratu panthawi yake. Mwachitsanzo, mu netiweki yogawa madzi, ma electromagnetic flow meter olumikizidwa ndi IoT amatha kuzindikira kutuluka kwa madzi kapena njira zosazolowereka nthawi yomweyo. Deta ikhoza kusanthulidwa kuti ilosere zosowa zosamalira, kukonza kugawa kwa madzi, ndikuchepetsa kutayika kwa madzi. Kulumikizana kumeneku kumathandizanso kuphatikizana bwino ndi zida zina zanzeru ndi machitidwe m'chilengedwe cha mafakitale.

Ma electromagnetic flow meter amakono ali ndi luso lodziwonera okha. Amatha kuyang'anira momwe amagwirira ntchito nthawi zonse, kuyang'ana mavuto monga kuwonongeka kwa ma electrode, kusakhazikika kwa mphamvu ya maginito, kapena mavuto olumikizirana. Kudzera mu kusanthula kwa magawo amkati, ma meter awa amatha kulosera kulephera komwe kungachitike asanachitike. Mwachitsanzo, ngati meter izindikira kuwonjezeka pang'onopang'ono kwa kukana kwa electrode, imatha kudziwitsa ogwira ntchito yokonza, kuwalola kusintha electrode mwachangu. Njira yokonzeratu yokonzeratuyi imachepetsa nthawi yogwira ntchito yosakonzekera, yomwe ndi yofunika kwambiri m'mafakitale komwe kugwira ntchito kosalekeza ndikofunikira, monga kupanga magetsi kapena kupanga mafuta ndi gasi.

Njira zatsopano zoyatsira magetsi, monga kusakaniza magetsi kawiri ndi kusakaniza magetsi kwa master komwe kungakonzedwe, zikupangidwa kuti ziwongolere kulondola kwa magetsi oyendera magetsi. Njira zoyatsira magetsi izi zimachepetsa mphamvu ya zinthu monga phokoso lamagetsi lotsika, makamaka poyesa kuyenda kwa madzi olimba. Zotsatira zake, magetsi oyendera magetsi amakono amatha kupeza kulondola kwa muyeso wa ±0.5% kapena ngakhale ±0.2%, poyerekeza ndi mitundu yakale. Kuphatikiza apo, kuthekera kwa magetsi awa kwawonjezeka. Tsopano amatha kuyeza molondola kuchuluka kwa madzi, kuyambira kuyenda kochepa kwambiri mpaka kuyenda kwakukulu, popanda kuwononga kulondola. Izi zimapangitsa kuti zikhale zosinthika komanso zoyenera kugwiritsa ntchito mitundu yosiyanasiyana.

Ukadaulo wa makina oyezera kuyenda kwa magetsi ukusintha kwambiri. Kuyambira pakupita patsogolo pa kapangidwe ka masensa ndi kukonza zizindikiro mpaka kuphatikiza zinthu zanzeru komanso zolumikizidwa, zatsopanozi zikuwonjezera magwiridwe antchito, kudalirika, komanso kusinthasintha kwa makina oyezera kuyenda kwa magetsi. Chizolowezi chofuna kuchepetsa mphamvu zamagetsi ndi kugwiritsa ntchito zipangizo zapadera chikukulitsa kuchuluka kwa momwe amagwiritsidwira ntchito, pomwe kulondola bwino komanso kuthekera kosiyanasiyana kukuwapangitsa kukhala zida zoyezera zolondola kwambiri. Pamene mafakitale akupitilizabe kufunafuna magwiridwe antchito apamwamba, zochita zokha, komanso zisankho zoyendetsedwa ndi deta, ukadaulo wa makina oyezera kuyenda kwa magetsi mosakayikira udzakhala ndi gawo lofunikira pakukwaniritsa zofunikirazi. Tsogolo lili ndi lonjezo lochulukirapo, ndi kupita patsogolo kwina komwe kukuyembekezeka m'malo monga kusanthula kwa luntha lochita kupanga kwa deta ya makina oyezera kuyenda ndi kuphatikiza ukadaulo wapamwamba kwambiri wolumikizirana.
