The
electromagnetic flowmeterwapangidwa ndi zigawo ziwiri: chosinthira ndi sensa, kotero maginito flowmeter amagawidwa mu mitundu iwiri ya dongosolo: Integrated ndi olekanitsidwa. Split electromagnetic flowmeter itha kugwiritsidwa ntchito m'malo osaphulika komanso zochitika zomwe zili ndi zofunikira zapadera. Masiku ano, makina opanga ma flowmeter a Q&T instrument amasanthula kwambiri mfundo zotsatirazi kuti muyike ndikugwiritsa ntchito splitter electromagnetic flowmeter.
1. Sensa ya kugawanika kwa electromagnetic flowmeter iyenera kukhazikitsidwa molunjika, ndipo madzi amadzimadzi amayenera kuyenda kuchokera pansi kupita pamwamba kuti akwaniritse chikhalidwe cha kusakaniza cholimba ndi madzi.
Chifukwa chake ndi chakuti chinthu cholimba (mchenga, tinthu tating'onoting'ono, ndi zina zotero) m'kati mwake chimakhala ndi mvula. Kuphatikiza apo, ngati pali nsomba ndi namsongole mu payipi, kuyenda kwa nsomba mu payipi kumapangitsa kuti kutuluka kwa flowmeter kugwedezeke mmbuyo ndi mtsogolo; kugwedezeka kumbuyo ndi kutsogolo kwa namsongole atapachikidwa pafupi ndi electrode kumapangitsanso kuti kutuluka kwa flowmeter kukhala kosakhazikika. Sefa yachitsulo imayikidwa polowera kumtunda kwa flowmeter kuti atseke nsomba ndi udzu kulowa mu chubu choyezera.
2. Kugawanika kwa electromagnetic flowmeter kumalepheretsa payipi yoyipa kuti isayikidwe molakwika ndipo imayambitsa kupanikizika koyipa mu sensa. Pamene kutseka kumtunda ndi kumtunda mavavu pa nthawi yomweyo, ngati madzimadzi kutentha ndi apamwamba kuposa mpweya kutentha. Imachepa pambuyo pozizira, kuchititsa kupanikizika mu chubu kupanga kupanikizika koipa. Kuponderezedwa koyipa kumapangitsa kuti mzerewo uchoke panjira yachitsulo, zomwe zimapangitsa kuti ma elekitirodi atayike.
3. Onjezani valavu yoletsa kupanikizika koyipa pafupi ndi
kugawanika kwa electromagnetic flowmeterndipo mutsegule valavu kuti mugwirizane ndi kuthamanga kwa mlengalenga kuti muteteze kupanikizika koipa kuti zisapangidwe mu sensa. Pamene payipi ofukula chikugwirizana kunsi kwa mtsinje wa kugawanika electromagnetic flowmeter, ngati valavu kumtunda kwa kachipangizo otaya ntchito kutseka kapena kusintha otaya, ndi zoipa mavuto adzapangidwa mu kuyeza chitoliro cha kachipangizo. Pofuna kupewa kupanikizika koipa, ndikofunikira kuwonjezera kupanikizika kumbuyo kapena kugwiritsa ntchito valve yotsika kuti musinthe ndi kutseka kutuluka.
