Zowononga, Zokhuthala, Zosagwira Ntchito: Ma Electromagnetic Meters Omwe Amayendetsa Madzi Onse

Ukadaulo wachikhalidwe woyezera kuyenda kwa madzi umavutika kuti ugwirizane ndi madzi ofunikira. Mwachitsanzo, mita ya turbine imadalira masamba ozungulira omwe amawonongeka mosavuta ndi tinthu tating'onoting'ono tomwe timayamwa kapena tomwe timayamwa ndi madzi okhuthala monga molasses kapena matope. Ma plate a orifice ndi machubu a Venturi amatha kutsekeka akamagwira ntchito ndi matope, pomwe zida zawo zachitsulo zimawonongeka mwachangu zikakhudzana ndi mankhwala monga hydrochloric acid kapena sodium hydroxide. Zolepheretsa izi zimapangitsa kuti zikhale zolondola: mita yotsekeka kapena yosweka imatha kusiyana ndi 10% kapena kuposerapo kuchokera ku kuchuluka kwenikweni kwa madzi, zomwe zimapangitsa kuti pakhale mlingo wolakwika mu njira zamankhwala, kuchuluka kwambiri kwa madzi, kapena kusatsatira malamulo azachilengedwe. Kwa mafakitale omwe zinthu zamadzimadzi zimasinthasintha—monga kukonza chakudya, komwe kukhuthala kumasintha ndi kutentha—mita yachikhalidwe imapereka kusinthasintha kochepa, komwe kumafuna kubwezeretsanso kapena kusintha pafupipafupi.

Ma electromagnetic flow meter amathetsa mavutowa pogwiritsa ntchito kapangidwe kosiyana kwambiri: amayesa kuyenda popanda kukhudzana mwachindunji ndi ziwalo zoyenda, pogwiritsa ntchito lamulo la Faraday la Electromagnetic Induction. Umu ndi momwe imagwirira ntchito: chitoliro cha mita chili ndi zinthu zosagwira mankhwala (monga PTFE, rabara, kapena ceramic), pomwe ma electrode awiri omwe ali mkati mwake amapanga mphamvu ya maginito kudutsa madzi. Pamene madzi oyendetsera magetsi akuyenda m'munda, amachititsa magetsi amagetsi molingana ndi liwiro lake—magetsi awa amayesedwa ndi ma electrode ndikusinthidwa kukhala deta ya kuchuluka kwa madzi. Kusowa kwa zigawo zoyenda kumachotsa kuwonongeka kwa zinthu zonyansitsa ndi kutsekeka kwa madzi okhuthala, pomwe chingwe chosakhala chachitsulo chimagwira ntchito ngati chotchinga ku zinthu zowononga. Kapangidwe kameneka kamatsimikizira kuti ma EMF amakhala olimba komanso olondola ngakhale akamagwira madzi omwe angawononge mamita achikhalidwe.

Chomwe chimapangitsa ma EMF kukhala osinthasintha kwenikweni ndi kuthekera kwawo kusintha momwe amagwirira ntchito ndi madzimadzi ambiri. Pamadzimadzi owononga—kuyambira ma acid a mafakitale ndi ma alkali mpaka madzi a m'nyanja ndi zosungunulira mankhwala—zipangizo za mita zimatha kusinthidwa kuti zigwirizane ndi ntchitoyo. Ma PTFE amalimbana ndi mankhwala ambiri achilengedwe ndi osapangidwa, zomwe zimapangitsa kuti akhale abwino kwambiri pamankhwala kapena mankhwala a petrochemical, pomwe ma raba amapambana pogwira matope owuma okhala ndi tinthu tating'onoting'ono tambiri, monga migodi kapena madzi otayira okhala ndi dothi. Madzi okhuthala, kuphatikizapo zomatira, mafuta odzola, ndi zakudya monga chokoleti kapena madzi a manyuchi, amayenda bwino kudzera mu chitoliro chosatsekedwa cha EMF, popanda njira zopapatiza zomwe zimayambitsa kusonkhana. Ngakhale madzi owuma okhala ndi mchenga, miyala, kapena zitsulo amadutsa popanda kuwononga mita, chifukwa palibe zinthu zozungulira zomwe zingawonongeke. Kusinthasintha kumeneku kumatanthauza kuti EMF imodzi imatha kuthana ndi mitundu yosiyanasiyana yamadzimadzi m'magawo osiyanasiyana azinthu, kuchepetsa kufunikira kwa ma meter apadera.

Kupatula kulimba, ma EMF amapereka kulondola komwe ndikofunikira kwambiri pakugwiritsa ntchito kofunikira. Amasunga kulondola mkati mwa ± 0.5% ya kuchuluka konse (ndipo nthawi zambiri kumakhala bwino) pamlingo wosiyanasiyana wa madzi, kuyambira kuthamanga kochepa (kotsika ngati 0.01 m/s) mpaka kuthamanga kwakukulu koyenera mapaipi amafakitale. Kulondola kumeneku ndikofunikira kwambiri pakukonza mankhwala, komwe kuwerengera molondola kwa zinthu zopangira kumatsimikizira kuti zinthuzo ndi zotetezeka, komanso pakukonza madzi otayira, komwe deta yolondola ya madzi imathandizira kutsatira malire otulutsira madzi. Ma EMF amachitanso bwino poyesa madzi osagwirizana, monga slurry okhala ndi zinthu zolimba zosiyanasiyana, zomwe zimasokoneza mita yachikhalidwe. Kutha kwawo kupereka deta yokhazikika komanso yodalirika ngakhale m'mikhalidwe yosakhazikika yamadzimadzi kumapangitsa kuti ikhale yofunika kwambiri m'mafakitale omwe kuwongolera njira ndikofunikira kwambiri.

Ubwino wa ma EMF umakhudzanso magwiridwe antchito komanso kusunga ndalama. Popeza palibe zida zosunthika zoti azisamalira kapena kuzisintha, zimafuna chisamaliro chochepa—nthawi zambiri zimangoyang'aniridwa nthawi ndi nthawi chaka chilichonse 1-3, poyerekeza ndi kukonza kotala la mita yamakina. Izi zimachepetsa nthawi yogwira ntchito komanso ndalama zokonzera, makamaka m'malo ovuta kufikako monga mapaipi apansi panthaka kapena mafakitale otentha kwambiri. Ma EMF ndi osavuta kuyika, ndi njira zopangira flange, wafer, kapena insertion mounting zomwe zimagwirizana ndi mapaipi omwe alipo popanda kusintha kwakukulu. Ma EMF ambiri amakono amaphatikiza kulumikizana kwa IoT, kulola kuwunika nthawi yeniyeni ya kuchuluka kwa madzi, machenjezo ozindikira kuwonongeka kwa lining kapena electrode foul, ndi remote calibration. Luntha la digito ili limalola kukonza mwachangu, kupewa kulephera kosayembekezereka ndikuwonetsetsa kuti ntchito ikuyenda bwino.

Kuyambira migodi, mafuta ndi gasi mpaka kukonza chakudya ndi mankhwala, ma EMF akhala chisankho chofunikira kwambiri kwa mafakitale omwe akulimbana ndi madzi olimba. M'mafakitale opanga mankhwala, amayesa zinthu zowononga molondola kwambiri, kuonetsetsa kuti zinthuzo zikuyenda bwino komanso moyenera. M'malo oyeretsera madzi akuda, amagwiritsa ntchito matope owuma komanso zinthu zoyeretsera zowononga, kupereka deta kuti akonze njira zoyeretsera. Mumakampani opanga zakudya ndi zakumwa, amayesa zinthu zokhuthala monga uchi kapena phala la phwetekere popanda kuipitsa madziwo kapena kukoma kwake. Ngakhale m'malo ovuta kwambiri—monga mapaipi amphamvu kwambiri kapena kugwiritsa ntchito cryogenic—ma EMF amapereka magwiridwe antchito ofanana, kutsimikizira kuti ndi osinthasintha m'magawo osiyanasiyana.

Pamene njira zamafakitale zikukula kwambiri ndipo mavuto amadzimadzi akuchulukirachulukira, kufunikira kwa muyeso wodalirika komanso wosinthika wamadzimadzi kudzangowonjezeka. Ma electromagnetic flow meter amadziwika ngati yankho lomwe silimangoyesa madzimadzi okha—limawagonjetsa. Mwa kugwiritsa ntchito madzi owononga, okhuthala, komanso okhuta mosavuta, amachotsa kusiyana pakati pa kulimba ndi kulondola komwe kumavutitsa ma meter achikhalidwe. Kwa mabizinesi, izi zikutanthauza kuchepetsa ndalama, kukonza kuwongolera njira, komanso mtendere wamumtima podziwa kuti muyeso wawo wamadzimadzi ndi woyenera vuto lililonse.

Mu dziko lomwe madzi ndi moyo wa mafakitale, ma electromagnetic flow meter ndi ngwazi zosayamikirika zomwe zimapangitsa kuti zinthu ziziyenda bwino. Amatsimikizira kuti ngakhale madziwo akhale olimba bwanji, kuyeza molondola sikungotheka kokha - ndi kothandiza. Pamene ukadaulo ukupita patsogolo, ma EMF apitilizabe kusintha, kupereka mphamvu ndi nzeru zambiri. Koma pakadali pano, akadali muyezo wagolide wogwiritsira ntchito madzi ovuta kwambiri, kufotokozeranso zomwe zingatheke poyezera madzi m'mafakitale.
