Ma Electromagnetic Flow Meters a Conductive Fluids: Abwino Kwambiri pa Chakudya, Mankhwala ndi Ma Petrochemical Sectors

Pakati pa ma electromagnetic flow meter oyenera kugwiritsa ntchito madzi oyendetsera magetsi ndi lamulo la Faraday la Electromagnetic Induction. Mosiyana ndi makina oyendera magetsi omwe amadalira zinthu zoyenda (zomwe zimatha kutsekeka, kuwonongeka, kapena kuipitsa madzi oyendetsera magetsi), magmeter amagwiritsa ntchito njira yosalowerera: chitoliro chokhala ndi zinthu zotetezera kutentha, chozunguliridwa ndi ma coil amagetsi. Madzi oyendetsera magetsi akamayenda mu chitoliro, amadula mphamvu ya maginito yopangidwa ndi ma coil, ndikupanga magetsi ochepa amagetsi. Kukula kwa magetsi amenewa kumagwirizana mwachindunji ndi liwiro la madzi—kulola mita kuwerengera kuchuluka kwa madzi molondola kwambiri (nthawi zambiri ± 0.5% ya kuwerenga, komanso ngakhale ± 0.1% ya mitundu yolondola kwambiri). Kapangidwe kameneka kamachotsa kukhudzana pakati pa zigawo zowunikira za mita ndi madzi, phindu lalikulu la madzi oyendetsera magetsi omwe angakhale owononga, okhuthala, kapena otsala.

Kwa makampani opanga chakudya, komwe ukhondo ndi kuyera kwa zinthu sizingakambiranedwe, ma electromagnetic flow meter ndi osintha kwambiri. Madzi oyendetsera mpweya monga madzi a zipatso, mkaka, sosi, ndi manyuchi amafunika zida zomwe zimakwaniritsa miyezo yokhwima ya FDA (Food and Drug Administration) kapena EU 10/2011 kuti apewe kuipitsidwa. Magawo osalala, opanda ming'alu a magmeter (nthawi zambiri opangidwa ndi zinthu zapamwamba monga PTFE kapena ETFE) amaletsa kuchulukana kwa madzi ndipo ndi osavuta kuyeretsa—ofunika kwambiri popewa kukula kwa mabakiteriya pakati pa nthawi yopangira. Mwachitsanzo, mu chomera chachikulu cha zakumwa, magmeter amagwiritsidwa ntchito kuyeza kuyenda kwa madzi oyendetsera mpweya m'matanki osakaniza: kulondola kwawo kumatsimikizira kutsekemera kosalekeza m'magulu osiyanasiyana, pomwe kapangidwe kawo kosalowerera kumachotsa chiopsezo cha tinthu tachitsulo (kuchokera ku ziwalo zosweka zamakina) kuipitsa chinthucho. Kuphatikiza apo, magmeter amagwira ntchito yokhuthala kwambiri yamadzi monga chokoleti kapena uchi popanda kutsekeka, vuto lofala ndi ma meter achikhalidwe omwe amadalira ma impeller.

Gawo la mankhwala lili ndi zofunikira kwambiri, chifukwa madzi oyendetsera mpweya (monga mankhwala amadzimadzi, madzi osabala, ndi mankhwala osungunulira) ayenera kukwaniritsa miyezo yolimba yowongolera khalidwe ndi kutsatira. Ma electromagnetic flow meter ndi abwino kwambiri popereka miyeso yolondola komanso yobwerezabwereza—yofunikira kuti zitsimikizire kuti mankhwalawo ali ndi mlingo woyenera wa zosakaniza zogwira ntchito. Kapangidwe kawo kosalowerera kumathandiziranso kukonza kopanda poizoni: popeza palibe ziwalo zosuntha mkati mwa chitoliro, palibe chiopsezo cha kupanga tinthu tating'onoting'ono kapena kuipitsidwa pakati pa magulu. Wopanga mankhwala wopanga mankhwala obayidwa, mwachitsanzo, amagwiritsa ntchito magmeter kuti ayang'anire kuyenda kwa madzi oyendetsera mpweya m'mabotolo. Kutumiza deta kwa ma meter nthawi yeniyeni kumalola fakitale kutsatira gawo lililonse la njirayi, kuonetsetsa kuti ikutsatira malamulo a mabungwe olamulira monga FDA ndi EMA (European Medicines Agency). Kuphatikiza apo, magmeter amalimbana ndi zinthu zotsukira zolimba (monga hydrogen peroxide) zomwe zimagwiritsidwa ntchito m'malo opangira mankhwala, kuonetsetsa kuti zimakhala zodalirika kwa nthawi yayitali.

Mu makampani opanga mafuta, komwe madzi oyendetsera mpweya amasiyana kuyambira mafuta osaphika ndi mafuta mpaka zosungunulira za mafakitale ndi madzi otayira, ma electromagnetic flow meter amagwira ntchito zovuta kwambiri poyesa. Kudzimbiritsa ndi vuto lalikulu pano—madzi ambiri a petrochemical amawononga kwambiri, ndipo ma mechanical meter okhala ndi zigawo zachitsulo amatha kuwonongeka mwachangu, zomwe zimapangitsa kuti kuwerenga kukhale kolakwika komanso kutayikira kokwera mtengo. Ma waya a ma magmeter osagwira dzimbiri (monga rabara kapena ceramic) ndi zinthu zonyowa zosagwiritsa ntchito chitsulo zimapirira madzi amphamvu awa, zomwe zimawonjezera moyo wawo mpaka zaka 10-15 (poyerekeza ndi zaka 3-5 za ma mechanical meter). Kuphatikiza apo, zomera za petrochemical nthawi zambiri zimagwira ntchito pansi pa kuthamanga kwambiri ndi kutentha, ndipo magmeter amapezeka m'mapangidwe olimba omwe amatha kuthana ndi kupsinjika mpaka 1,000 bar ndi kutentha kuyambira -40°C mpaka 200°C. Mwachitsanzo, fakitale yoyeretsera imagwiritsa ntchito magmeter kuti ayesere kuyenda kwa mafuta osaphika oyendetsera mpweya kudzera m'mapaipi: kulondola kwawo kumathandiza kukonza njira zoyeretsera, kuchepetsa zinyalala, ndikuwonetsetsa kuti mayendedwe otetezeka—ofunikira kwambiri popewa kutayikira kwa chilengedwe ndikukwaniritsa malamulo achitetezo.

Ngakhale kuti zoyezera kuyenda kwa magetsi zamagetsi zimakhala ndi mtengo wapamwamba kwambiri kuposa njira zina zamakanika, ubwino wawo wa nthawi yayitali pazakudya, mankhwala, ndi mafuta ndi woposa kwambiri ndalama zomwe zagwiritsidwa ntchito. Kuchepa kwa ndalama zokonzera (palibe zida zosunthira zoti zilowe m'malo), kuchepa kwa zinthu zomwe zasungidwa (chifukwa chopewa kuipitsidwa), komanso kuyendetsa bwino ntchito (kudzera mu deta yolondola) kumapangitsa kuti ndalamazo zibwere mkati mwa zaka 2-3. Kwa mafakitale omwe ngakhale zolakwika zazing'ono zoyezera zimatha kukhala ndi zotsatira zoopsa - kuyambira chakudya chowonongeka mpaka mankhwala osagwira ntchito kapena masoka achilengedwe - magmeter si chida chokha, koma chitetezo.

Pamene magawo azakudya, mankhwala, ndi mafuta a petrochemical akupitilizabe kusintha, ndi malamulo okhwima komanso kufunikira kowonjezereka kwa zinthu zokhazikika, ma electromagnetic flow mita akadali muyezo wagolide woyezera madzi oyendetsera mpweya. Kutha kwawo kuphatikiza kulondola, ukhondo, ndi kulimba kumapangitsa kuti zikhale zofunikira kwambiri pakuwonetsetsa kuti zinthu zili bwino, chitetezo cha ntchito, komanso kutsatira malamulo a chilengedwe. Pa malo aliwonse omwe amagwiritsa ntchito madzi oyendetsera mpweya, ma magmeter ndi njira yoposa njira yoyezera—ndiwo ofunikira kwambiri kuti zinthu ziyende bwino m'malo ampikisano komanso olamulidwa.
