Kusanthula zolakwika ndi njira yothetsera vuto la electromagnetic flowmeter

Pazida zamagetsi zamagetsi zamafakitale, mfundo yoyezera ya electromagnetic flowmeter ndi lamulo la Faraday la induction ya electromagnetic. Kapangidwe ka electromagnetic flowmeter makamaka kamapangidwa ndi maginito circuit system, measure conduit, electrode, shell, lining ndi converter. Amagwiritsidwa ntchito makamaka poyesa kuchuluka kwa madzi otulutsa mpweya ndi slurry m'mapaipi otsekedwa. Kuphatikiza ma acid, alkalis, mchere ndi zakumwa zina zowononga kwambiri. Chogulitsachi chimagwiritsidwa ntchito kwambiri mu mafuta, mankhwala, zitsulo, nsalu, chakudya, mankhwala, kupanga mapepala ndi mafakitale ena, komanso kuteteza chilengedwe, kasamalidwe ka mizinda, zomangamanga zosamalira madzi ndi madera ena.
Pogwiritsa ntchito electromagnetic flowmeter, zida zina zimalephera kugwira ntchito. Nthawi zambiri pamakhala mitundu iwiri ya kulephera kugwira ntchito: yoyamba ndi kulephera kwa chida chokha, ndiko kuti, kulephera komwe kumachitika chifukwa cha kuwonongeka kwa ziwalo kapena zigawo za chida; yachiwiri, kulephera komwe kumachitika chifukwa cha zinthu zakunja, monga kuyika molakwika, kusokonekera kwa kayendedwe ka madzi, kuyika ndi kukula, ndi zina zotero.
Pamene electromagnetic flowmeter yalephera, nthawi zambiri timafunika kuwunika kuti ndi gawo liti lomwe lalakwika kenako nkupeza momwe tingakonzere vutoli.

1. Zolakwika zomwe zimachitika kawirikawiri pa electromagnetic flowmeter - electromagnetic flowmeter ilibe chizindikiro chotuluka
Kulephera kwamtunduwu kumachitika kawirikawiri mukamagwiritsa ntchito, ndipo zifukwa zake nthawi zambiri ndi izi:
(1) Mphamvu ya chipangizocho si yachilendo;
(2) Kulumikizana kwa chingwe ndi kutuluka kwa bolodi lamagetsi sikwabwinobwino;
(3) Kuyenda kwa madzi sikukwaniritsa zofunikira pakuyika;
(4) Zigawo za sensa zawonongeka kapena pali guluu pakhoma lamkati la muyeso;
(5) Zigawo zosinthira zowonongeka
Kodi kuthetsa vutoli n'kotani?
Ngati izi zitachitika, choyamba onani ngati magetsi a chipangizocho ali ndi vuto, tsimikizirani kuti magetsi alumikizidwa, onani ngati mphamvu yotulutsa ya bolodi lamagetsi ndi yabwinobwino, kapena yesani kusintha bolodi lonse lamagetsi kuti muwone ngati lili bwino. Onetsetsani kuti zingwe zili bwino ndipo zalumikizidwa bwino. Onani momwe madzi akuyendera ndipo madzi omwe ali mu chitolirocho ali odzaza. Ngati palibe madzi mu sensa, muyenera kusintha chubu kapena kusintha njira yoyikira. Yesani kuyiyika moyimirira.
2. Chizindikiro cha electromagnetic flowmeter chikuchepa pang'onopang'ono kapena chizindikirocho chikutsika mwadzidzidzi
Zolakwika zambirizi zimachitika chifukwa cha mphamvu ya choyezera kapena malo akunja, ndipo vutolo limatha kuchotsedwa lokha pambuyo poti kusokoneza kwakunja kwachotsedwa. Pofuna kutsimikizira kulondola kwa muyeso, zolephera zotere sizinganyalanyazidwe. M'malo ena opangira, chifukwa cha kugwedezeka kwakukulu kwa chitoliro choyezera kapena madzi, bolodi la circuit la flowmeter lidzamasulidwa, ndipo mtengo wotulutsa ungasinthenso.
Kodi kuthetsa vutoli n'kotani?
(1) Tsimikizirani ngati ndi chifukwa cha ntchito ya njirayi, ndipo madziwo akuthamanga. Panthawiyi, flowmeter imangowonetsa momwe madziwo alili, ndipo vutolo limatha lokha pulsation itatha.
(2) Kusokonezeka kwa maginito chifukwa cha mafunde akunja osochera, ndi zina zotero. Yang'anani ngati pali zipangizo zazikulu zamagetsi kapena makina ochapira magetsi omwe akugwira ntchito pamalo ogwirira ntchito a chipangizocho, ndipo onetsetsani kuti chipangizocho chili pansi ndipo malo ogwirira ntchito ali bwino.
(3) Pamene payipi sidzadza ndi madzi kapena madziwo ali ndi thovu la mpweya, zonsezi zimachitika chifukwa cha njira yogwirira ntchito. Panthawiyi, katswiri angapemphedwe kuti atsimikizire kuti phindu lotulutsa likhoza kubwerera mwakale madziwo akadzaza kapena thovu la mpweya litakhazikika.
(4) Bolodi ya dera la chotumizira ndi yolumikizidwa ndi pulagi. Chifukwa cha kugwedezeka kwakukulu kwa payipi yoyezera kapena madzi omwe ali pamalopo, bolodi lamagetsi la flowmeter nthawi zambiri limamasuka. Ngati ndi lotayirira, flowmeter ikhoza kuchotsedwa ndipo bolodi ya dera ikhoza kukonzedwanso.

3. Mfundo ya zero ya electromagnetic flowmeter ndi yosakhazikika
Kusanthula Chifukwa
(1) Paipiyo sidzadza ndi madzi kapena madziwo ali ndi thovu la mpweya.
(2) Mwachidule, amakhulupirira kuti palibe madzi otuluka mu chubu cha pampu, koma kwenikweni pali madzi otuluka pang'ono.
(3) Zifukwa za madzi (monga kusafanana bwino kwa kayendedwe ka madzi, kuipitsidwa kwa ma electrode, ndi zina zotero).
(4) Kuteteza kwa magetsi kwa circuit ya chizindikiro kumachepetsedwa.
Kodi kuthetsa vutoli n'kotani?
Ndikofunikira kuwona ngati cholumikiziracho chili ndi mapaipi odzaza ndi mapayipi komanso ngati pali thovu la mpweya mu cholumikiziracho. Ngati pali thovu la mpweya, chochotsera mpweya chikhoza kuyikidwa pamwamba pa thovu la mpweya. Kukhazikitsa kopingasa kwa chidacho kungasinthidwenso kukhala choyimirira. Onani ngati chidacho chili pansi bwino. Kukana kwa nthaka kuyenera kukhala kochepera kapena kofanana ndi 100Ω; mphamvu ya cholumikiziracho siyenera kukhala yochepera 5μs/cm. Ngati cholumikiziracho chisonkhana mu chubu choyezera, chiyenera kuchotsedwa nthawi yake. Pewani kukanda mkati mwa cholumikiziracho mukachotsa.
