Muyeso wolondola kwambiri:
Ma electromagnetic flowmeters amagwira ntchito motsatira lamulo la Faraday la electromagnetic induction. Pamene madzi oyendetsera mpweya (madzi akumwa ndi madzi ali ndi mphamvu inayake yoyendetsera mpweya) akuyenda mu mphamvu ya maginito, mphamvu yamagetsi yoyendetsedwa imapangidwa, ndipo kukula kwake kumafanana ndi kuchuluka kwa madzi akumwa. Pogwiritsa ntchito njira zoyezera madzi akumwa ndi madzi, njira iyi yoyezera imatha kupereka deta yolondola kwambiri ya madzi akumwa. Mwachitsanzo, mu njira yoyezera mankhwala a madzi akumwa, kuyeza kolondola kwa madzi akumwa kungatsimikizire kuti mankhwala ndi madzi akumwa asakanikirana bwino kuti akwaniritse zotsatira zabwino kwambiri zoyezera madzi akumwa.
Zigawo zoyenda mwaulere:
Choyezera kuyenda kwa madzi mu electromagnetic chilibe zinthu zamkati zomwe zimalepheretsa kuyenda kwa madzi, monga madzi osaphika okhala ndi matope, algae ndi zinthu zina zosafunika mu chomera chamadzi, ndipo kapangidwe ka zinyalala ndi kovuta, komwe kungakhale ndi tinthu tolimba, ulusi ndi zinthu zina. Choyezera kuyenda kwa madzi mu electromagnetic sichidzatsekedwa chifukwa cha zinyalalazi, zomwe zingatsimikizire kuti madziwo akuyenda bwino, kuchepetsa ndalama zosamalira zida ndi cholakwika choyezera chomwe chimachitika chifukwa cha kuchulukana kwa madzi.
Chiŵerengero cha mitundu yosiyanasiyana:
Mungathe kuyeza kuchuluka kwa madzi kuyambira otsika kwambiri mpaka okwera kwambiri. Mu dongosolo la madzi la chomera chamadzi, madzi omwe amagwiritsidwa ntchito nthawi zosiyanasiyana amasiyana kwambiri, monga nthawi yomwe madzi amagwiritsidwa ntchito masana komanso nthawi yomwe madzi amalowa usiku, choyezera madzi chamagetsi chimatha kuyeza molondola kuchuluka kwa madzi pansi pa madzi osiyanasiyana ndikusintha momwe madzi amayendera. Mu chomera chamadzi otayira madzi, madzi otayira madzi pazigawo zosiyanasiyana zoyeretsera madzi nawonso amakhala ndi kusintha kwakukulu, ndipo choyezera madzi chamagetsi chimathanso kuthana nacho bwino.
Mphamvu yoyezera mbali ziwiri:
Mu njira zina zoyeretsera madzi ndi zimbudzi, madzi amatha kuyenda mobwerera m'mbuyo. Mwachitsanzo, m'makina ena oyendera madzi kapena malo opopera madzi m'malo oyeretsera madzi, kusintha kwa madzi kumatha kuchitika panthawi yoyambitsa zida kapena kuthetsa mavuto. Ma electromagnetic flowmeter amatha kuyeza molondola kuyenda kwa madzi kutsogolo ndi kumbuyo, kupereka deta yonse yogwiritsira ntchito ndi kuyang'anira makina.
Malo okhazikitsa
Kusankha malo:
Pofuna kutsimikizira kulondola kwa muyeso, choyezera kuyenda kwa magetsi chiyenera kuyikidwa mu payipi komwe madzi akuyenda bwino. Mu dongosolo la mapaipi a zimbudzi ndi zomera zamadzi, ndikofunikira kupewa kuyika pafupi ndi zigawo zotsutsana ndi malo monga zigongono ndi ma tees a mapaipi. Mwachitsanzo, ngati choyezera kuyenda kwa magetsi chayikidwa pafupi kwambiri ndi malo otsika a chigongono mu payipi yonyamula matope ya fakitale ya zimbudzi, cholakwika choyezera chidzachitika chifukwa cha vortex ndi liwiro losafanana la madzi pa chigongono. Malo abwino oyikapo ndi gawo la chitoliro cholunjika, kutalika kwa gawo la chitoliro cholunjika cha mmwamba nthawi zambiri kumalimbikitsidwa kukhala nthawi 5-10 kuposa m'mimba mwake wa chitoliro, ndipo kutalika kwa gawo la chitoliro cholunjika cha m'munsi nthawi zambiri kumakhala nthawi 3-5 kuposa m'mimba mwake wa chitoliro.
Zofunikira pa nthaka:
Kukhazikika bwino ndi chinthu chofunikira kwambiri pakugwira ntchito bwino kwa ma electromagnetic flowmeter. Chifukwa chakuti electromagnetic flowmeter imadalira mfundo yoyendetsera magetsi, kuzindikira molondola chizindikiro kumafuna kukhazikika koyenera. Mu malo osungira zinyalala ndi madzi, chifukwa pakhoza kukhala zida zamagetsi zambiri ndi magwero osokoneza, samalani kwambiri kukhazikika. Kawirikawiri, chipinda cha sensor cha electromagnetic flowmeter chiyenera kukhazikika padera, ndipo kukana kwa nthaka kuyenera kukhala kochepera 10Ω. Ngati chitolirocho chapangidwa ndi chitsulo, chitolirocho chingagwiritsidwenso ntchito ngati gawo la kukhazikika, koma onetsetsani kuti kulumikizana kwa nthaka kwa chitolirocho kuli bwino.
Zofunikira pa chubu chonse:
Ma electromagnetic flowmeter amafuna kuti madzi omwe ali mu chitoliro akhale mu chubu chokwanira. Mu siteshoni yokweza madzi a chitoliro cha chitoliro cha zinyalala, ndikofunikira kuonetsetsa kuti magawo osankhidwa ndi ogwirira ntchito a pampu ya zinyalala ndi oyenera, kuti zitoliro ziyende bwino mu chitolirocho. Ngati pali mpweya mu chitolirocho, izi zidzakhudza kufalikira kwa mphamvu ya maginito komanso kupanga mphamvu yamagetsi, zomwe zimapangitsa kuti muyeso ukhale wolakwika. Pa payipi yoperekera madzi ya chitoliro cha madzi, poyambitsa ndi kuyimitsa madzi, chisamaliro chiyenera kuperekedwanso kuti mpweya usalowe mu chitolirocho kuti zitsimikizire kuti chitoliro chonse cha chitoliro chamagetsi chikuyesedwa bwino.
Njira zodzitetezera pokonza
Yang'anani ma electrode nthawi zonse:
Electrode ndiye gawo lofunika kwambiri la electromagnetic flowmeter. Mu malo osungira zinyalala ndi zomera zamadzi, pamwamba pa electrode pakhoza kukhala ndi zonyansa m'madzi, monga mafuta ndi sikelo m'zinyalala. Kuyeretsa electrode nthawi zonse kumatsimikizira kulondola kwa muyeso. Nthawi zambiri, njira yoyeretsera mankhwala ingagwiritsidwe ntchito kusankha chotsukira choyenera malinga ndi kapangidwe ka dothi la pamwamba pa electrode. Mwachitsanzo, ngati pamwamba pa electrode pali sikelo ya calcium carbonate, mutha kugwiritsa ntchito yankho la hydrochloric acid losungunuka poyeretsa, koma samalani kutsuka ndi madzi mutatsuka kuti mupewe chotsukira chotsalira pa electrode ndi madzi.
Yang'anani momwe zinthu zilili padenga:
Chipinda cha electromagnetic flowmeter chingateteze thupi la sensa, komanso chimakhudza kulondola kwa muyeso. Pakugwira ntchito kwa nthawi yayitali kwa zinyalala ndi zomera zamadzi, chipindacho chikhoza kutsukidwa ndikudyedwa ndi madzi. Mwachitsanzo, pamene mafakitale a zinyalala akusamalira zinyalala zamafakitale zomwe zili ndi asidi wambiri kapena alkalescence, chipindacho chikhoza kudyedwa. Ndikofunikira kuyang'ana nthawi zonse ngati chipindacho chawonongeka, chakalamba, ndi zina zotero, ndikuyikanso chipindacho nthawi yake kuti muwonetsetse kuti mita yoyendera ikugwira ntchito bwino.
Kuyang'ana mzere wa chizindikiro:
Mzere wa chizindikiro cha electromagnetic flowmeter umatumiza chizindikiro choyezera, ndipo m'malo ovuta a mafakitale a zimbudzi ndi zomera zamadzi, mzere wa chizindikiro ukhoza kusokonezedwa ndi maginito, chinyezi ndi zina zotero. Yang'anani nthawi zonse ngati kulumikizana kwa mzere wa chizindikiro kuli kolimba, ngati pali kuwonongeka ndi zina zotero. Ngati mzere wa chizindikiro wapezeka kuti uli ndi mavuto osokoneza, njira monga zingwe zotetezera zingagwiritsidwe ntchito kulimbitsa kukhazikika kwa kutumiza kwa chizindikiro.
