Ma electromagnetic flowmetersamagwiritsidwa ntchito kwambiri m'mafakitale kuti ayese bwino kayendedwe ka madzi. Komabe, pali zochitika zingapo pomwe kugwiritsa ntchito kwawo sikungakhale koyenera.
1. Madzi Osayendetsa Ma Conductor
Ma electromagnetic flowmetersamagwira ntchito motsatira lamulo la Faraday la kulowetsa magetsi m'magetsi. Amafuna kuti madzi omwe akuyesedwa akhale oyendetsera magetsi. Madzi oyendetsera magetsi akamayenda kudzera mu mphamvu ya maginito, magetsi amapangidwa m'mimba mwake mwa chubu choyendera madzi, zomwe zimagwirizana ndi liwiro la madziwo. Pa madzi osakhala oyendetsera magetsi monga ma hydrocarbon ambiri (monga mafuta, dizilo), madzi oyera omwe ali mu mkhalidwe wochepa kwambiri wa ionized, ndi zinthu zambiri zachilengedwe, magetsi oyendetsedwa ndi magetsi amakhala otsika kwambiri kapena sapezeka. M'mikhalidwe yotereyi, electromagnetic flowmeter singathe kuyeza molondola kuchuluka kwa madzi chifukwa ilibe chowongolera mpweya chofunikira kuti ipange magetsi oyendetsedwa ndi magetsi oyezeka.
2. Madzi Okhala ndi Zinthu Zolimba Kwambiri kapena Tinthu Tomwe Timakhala ndi Zinthu Zosalimba
Madzi okhala ndi tinthu tating'onoting'ono tolimba kapena zinthu zokwawa zimatha kuyambitsa mavuto akulu pa ma electromagnetic flowmeter. Chipinda chamkati cha chubu choyendera mu electromagnetic flowmeter n'chofunikira kwambiri pakugwira ntchito bwino kwa mita. Tinthu tokwawa mu madzi timatha kuwononga pang'onopang'ono chipindacho pakapita nthawi. Pamene chipindacho chikutha, zimatha kusokoneza kulondola kwa muyeso wa voltage woyambitsidwa. Kuphatikiza apo, tinthu tating'onoting'ono tingayambitsenso kutsekeka kwa ma electrode a flowmeter. Ma electrode awa ndi ofunikira pozindikira voltage yoyambitsidwa. Kutsekeka kumatha kusokoneza kulumikizana kwamagetsi pakati pa madzi ndi ma electrode, zomwe zimapangitsa kuti kuyenda kukhale kolakwika kapena kosakhazikika. Mwachitsanzo, m'mapaipi a slurry omwe slurry ili ndi mchere wambiri wokwawa, electromagnetic flowmeter singakhale chisankho chabwino kwambiri chifukwa nthawi yake yogwira ntchito komanso kulondola kwake koyezera kungasokonezeke kwambiri.
3. Mikhalidwe Yotsika Yoyendera
Ma electromagnetic flowmetersali ndi liwiro lochepa loyenda pansi pake lomwe magwiridwe antchito awo amachepa. Pa liwiro lotsika kwambiri la kuyenda, mphamvu yamagetsi yomwe imapangidwa ndi madzi oyenda ndi yochepa kwambiri. Mphamvu yamagetsi yaying'ono iyi imatha kukhudzidwa mosavuta ndi phokoso lamagetsi ndi magwero ena osokoneza. Chiŵerengero cha phokoso la chizindikiro - mpaka - chimakhala chosasangalatsa, zomwe zimapangitsa kuti mita ikhale yovuta kusiyanitsa molondola mphamvu yamagetsi yomwe imayambitsidwa yokhudzana ndi kuyenda ndi phokoso lakumbuyo. Zotsatira zake, kulondola kwa muyeso wa electromagnetic flowmeter m'mikhalidwe yotsika nthawi zambiri kumakhala koipa, ndipo sikungathe kupereka deta yodalirika ya liwiro la kuyenda. Izi ndizofunikira kwambiri pamagwiritsidwe ntchito komwe liwiro la kuyenda limasiyana kwambiri ndipo lingatsike mpaka pamtengo wotsika kwambiri kwa nthawi yayitali, monga m'njira zina zazing'ono zamankhwala kapena m'makina operekera madzi panthawi yomwe kufunikira kochepa kukufunika.
4. Malo Otentha Kwambiri ndi Opanikizika Kwambiri (Opitirira Malire Ovomerezeka)
Chida chilichonse choyezera magetsiYapangidwa kuti igwire ntchito mkati mwa kutentha ndi kuthamanga kwapadera. Ngati kutentha kwa madzi kapena kuthamanga kwapitirira malire awa, kungayambitse mavuto. Kutentha kwambiri kungakhudze mawonekedwe ndi mphamvu zamagetsi za zinthu zomwe zimagwiritsidwa ntchito mu flowmeter, monga zinthu zolumikizira ndi kutenthetsa kwa ma electrode. Mkati mwake mutha kufutukuka, kufupika, kapena kuwonongeka kutentha kwambiri, zomwe zingayambitse kutuluka kapena kusintha kwa mawonekedwe a flow chubu, motero zimakhudza kulondola kwa muyeso. Mofananamo, kuthamanga kwambiri kumatha kuyika kupsinjika kwakukulu pa flow chubu ndi zigawo zake. Ngati kuthamanga kuli kwakukulu kwambiri, kungayambitse flow chubu kusokonekera kapena kuphulika, zomwe zimapangitsa flowmeter kusagwira ntchito. Mu ntchito zokhudzana ndi madzi otentha kwambiri, monga m'mafakitale ena otentha kwambiri, kapena m'mapaipi amphamvu kwambiri mumakampani amafuta ndi gasi komwe kuthamanga kumatha kufika pamlingo wapamwamba kwambiri, electromagnetic flowmeter singakhale yoyenera pokhapokha ngati yapangidwira makamaka mikhalidwe yovuta kwambiri.
Pomaliza, pamenezoyezera kuyenda kwa magetsiPopeza pali ubwino wambiri poyesa kuyenda kwa madzi, ndikofunikira kuganizira mosamala mtundu wa madzi, momwe amagwirira ntchito, ndi makhalidwe a kuyenda kwa madzi kuti mudziwe ngati ndi chisankho choyenera kwambiri. Muzochitika zomwe zafotokozedwa pamwambapa, njira zina zoyezera kuyenda kwa madzi zingakhale zoyenera kwambiri kuti zitsimikizire kuti kuchuluka kwa madzi ndi kolondola komanso kodalirika.
