Chida choyezera kuyenda kwa magetsi (EMF), chomwe chimadziwikanso kuti magmeter/mag flowmeter, ndi chida chomwe chimagwiritsidwa ntchito kwambiri poyesa kuchuluka kwa madzi oyendetsera magetsi m'mafakitale ndi m'mizinda. Chidachi chingapereke njira yodalirika komanso yosasokoneza yoyezera kuyenda kwa madzi pogwiritsa ntchito lamulo la Faraday, yoyenera kugwiritsa ntchito madzi okhala ndi mphamvu yoyendetsera magetsi yoyenera.
Mphamvu yake yosonkhezera ma electromotive E ikhoza kufotokozedwa ndi njira iyi:
E=KBVD
Kumene
K = Chosasintha cha Flowmeter
B = Mphamvu ya maginito yopangira mphamvu
V= liwiro lapakati la kuyenda kwa madzi m'chigawo chopingasa cha chitoliro choyezera
D= M'mimba mwake wa chitoliro choyezera
Mfundo Yogwirira Ntchito
Mfundo yaikulu yogwiritsira ntchito mag flowmeter ndi lamulo la Faraday lokhudza kulowetsa mphamvu zamagetsi. Limanena kuti pamene kondakitala akuyenda kudzera mu mphamvu ya maginito, mphamvu yamagetsi imayambitsidwa.
Makamaka pa ntchito ya electromagnetic flowmeter, madzi oyendetsera magetsi omwe amayenda mu chitoliro cha chidacho amagwira ntchito ngati kondakitala. Ma coil awiri amapanga mphamvu ya maginito yofanana yolunjika ku njira yoyendera. Mizere ya mphamvu ya maginito imadulidwa ndi kayendedwe ka madzi. Chifukwa chake, mphamvu yamagetsi yoyendetsedwa ndi magetsi imapangidwa kenako imamvedwa ndi ma electrode awiri achitsulo ndikusinthidwa kukhala chizindikiro chamagetsi chokhazikika.
Ubwino wa Kuyeza kwa Maginito
Kusavuta kwa kapangidwe kake:Kapangidwe ka EMF kalibe ziwalo zosuntha, zomwe kusakhalapo kwake kumachepetsa kuwonongeka kwa makina ndi kufunikira kokonza. Palinso chopinga chilichonse mkati mwa chitoliro chake choyezera chomwe chingayambitse kutsika kwa mutu wa kuthamanga ndi kutsekeka kwa cholumikizira chopingasa.
Zofunikira zochepa pakukhazikitsa:Kukhazikitsa EMF kumafuna kutalika kochepa kwa magawo owongoka a mapaipi okwera ndi otsika. Pogwira ntchito payokha, mag flowmeter sifunikira chosinthira mphamvu chosiyana kuti chithandizire kuyeza kwake. Kuyenda kumatha kuyezedwa mbali zonse ziwiri, kuchepetsa malire a momwe mita imayendera ndipo ndi yoyenera kugwiritsa ntchito kuyang'anira kuyenda mobwerera m'mbuyo.
Kugwirizana:Kuyeza kwa kayendedwe ka Mag kungawonetse magwiridwe antchito okhazikika komanso odalirika omwe samakhudzidwa ndi magawo apakati a kuthamanga, kutentha, kuchulukana ndi kukhuthala. Zipangizo zosinthira zomwe zingasinthidwe ndi zitsulo za electrode cab sizimakhudzidwa ndi dzimbiri komanso kutopa, zomwe zimagwiritsidwa ntchito pamitundu yosiyanasiyana ya mankhwala amphamvu, slurry, komanso zinthu zamadzimadzi zomwe zimafuna ukhondo.
Kulondola:Njira yamagetsi imayesa molondola kwambiri pakati pa njira zosiyanasiyana zoyezera kuchuluka kwa madzi. Kulondola kwa EMF nthawi zambiri kumakhala ± 0.5% mpaka ± 0.2% ya kuwerenga.
Zoletsa
Kuyendetsa bwino kofunikira:Madzi oyezera a EMF amafunika kuti akhale ndi mphamvu yokwanira yoyendetsera mpweya (≥5μS/cm). Chifukwa chake mpweya ndi madzi osayendetsa mpweya sizingathe kuyeza kuyenda kwa magetsi pogwiritsa ntchito magetsi. Zinthu zodziwika bwino za mafakitale monga madzi oyeretsedwa ndi nthunzi, zosungunulira zachilengedwe ndi zinthu zamafuta sizingathe kugwiritsa ntchito njira yowunikira kuyenda kwa mpweya.
Chitoliro chodzaza mokwanira:Kugwira ntchito kwa EMF kumafuna kumiza kwathunthu ndi kukhudzana kosalekeza kwa ma electrode ndi madzi oyendetsera mpweya. Chifukwa chake, poyesa, njirayi iyenera kuwonetsetsa kuti gawo la chitoliro cha EMF ladzazidwa ndi sing'anga kuti ligwire bwino ntchito.
Kugwiritsa ntchito
Kutengera ndi mfundo yake yapadera yoyezera, electromagnetic flowmeter ndi yoyenera kwambiri poyezera madzi oyendetsera mpweya m'zochitika monga:
Kupereka Madzi:Kuyeza madzi osaphika olowera ndi madzi otulutsira madzi okonzedwa kuti azitha kuyang'anira madzi.
Kukonza Zinyalala: Kuyeza zinyalala za m'matauni, zinyalala za m'mafakitale, ndi matope ndi mphamvu yokwanira yoyendetsera madzi.
Mankhwala:Kuyeza ma acid osiyanasiyana, alkali, njira zamchere, ndi zinthu zina zowononga kwambiri pogwiritsa ntchito zingwe zoteteza dzimbiri ndi zinthu zamagetsi.
Chakumwa:Kuyeza zinthu zopangira, zinthu zapakatikati ndi zinthu zomalizidwa popanga mkaka, madzi a zipatso, zakumwa zoledzeretsa ndi zakumwa zina.
Zachitsulo:Kuyeza matope a mchere, matope a m'mbuyo, madzi a matope a malasha omwe amakonzedwa ndi zinthu zosatha.
Mphamvu:Kuyeza madzi ozizira ozungulira, condensate, mankhwala ochizira madzi m'mafakitale amagetsi, ndi zina zotero.
Shanghai Wangyuanali ndi zaka zoposa 20 zaukadaulo popanga ndi kukonza zida zoyezera. Chidziwitso chathu chambiri chaukadaulo ndi maphunziro a milandu m'magawo osiyanasiyana okhala ndi mitundu yonse ya zoyezera madzi zimatithandiza kupereka mayankho owunikira madzi omwe akwaniritsa zosowa zanu. Ngati pali mafunso ndi zosowa zilizonse zokhudza zoyezera madzi zamagetsi, chonde musazengereze kutilumikizana nafe.
