Kusanthula zolakwika wamba ndi yankho la electromagnetic flowmeter

Pazida zamagetsi zamagetsi zamagetsi, muyeso wa electromagnetic flowmeter ndi lamulo la Faraday la electromagnetic induction.Mapangidwe a electromagnetic flowmeter amapangidwa makamaka ndi maginito ozungulira, njira yoyezera, ma elekitirodi, chipolopolo, lining ndi chosinthira.Amagwiritsidwa ntchito kwambiri poyezera kuchuluka kwa madzi a conductive ndi slurries mu mapaipi otsekedwa.Kuphatikizapo ma asidi, alkalis, mchere ndi zakumwa zina zowononga kwambiri.Izi amagwiritsidwa ntchito kwambiri mu mafuta, mankhwala, zitsulo, nsalu, chakudya, mankhwala, papermaking ndi mafakitale ena, komanso kuteteza chilengedwe, kasamalidwe tauni, kasamalidwe madzi ndi madera ena.
Pogwiritsa ntchito electromagnetic flowmeter, zida zina zolephera zimachitika mosapeweka.Nthawi zambiri pali mitundu iwiri ya zolephera pakugwira ntchito: imodzi ndiyo kulephera kwa chida chokha, ndiko kuti, kulephera komwe kumachitika chifukwa cha kuwonongeka kwa zigawo zamagulu kapena zigawo za chida;chachiwiri, kulephera chifukwa cha zinthu zakunja, monga unsembe molakwika, otaya kupotoza, mafunsidwe ndi makulitsidwe, etc.
Pamene electromagnetic flowmeter ikulephera, nthawi zambiri timafunika kuwunika kuti ndi gawo liti lomwe lili ndi vuto ndikuwona momwe tingathetsere vutolo.

1. Zolakwika wamba za electromagnetic flowmeter - electromagnetic flowmeter ilibe linanena bungwe loyenda
Kulephera kwamtunduwu kumakhala kofala kwambiri pakagwiritsidwe ntchito, ndipo zifukwa zake ndizo:
(1) Mphamvu yamagetsi ya chipangizocho ndi yachilendo;
(2) Kulumikizana kwa chingwe ndi kutuluka kwa bolodi lamagetsi ndizovuta;
(3) Kuthamanga kwamadzimadzi sikukwaniritsa zofunikira za unsembe;
(4) Zigawo za sensa zimawonongeka kapena pali zomatira pa khoma lamkati la muyeso;
(5) Zowonongeka zosinthira
Kodi kuthetsa?
Izi zikachitika, choyamba fufuzani ngati magetsi a chipangizocho ndi olakwika, onetsetsani kuti magetsi akugwirizana, fufuzani ngati mphamvu yamagetsi yamagetsi yamagetsi ndi yachibadwa, kapena yesani kusintha gulu lonse lamagetsi kuti mudziwe. kaya zili bwino.Onetsetsani kuti zingwe zili bwino komanso zolumikizidwa bwino.Yang'anani momwe madzi amayendera ndipo madzi mu chitoliro ali odzaza.Ngati mulibe madzi mu sensa, muyenera kusintha chubu kapena kusintha njira yokhazikitsira.Yesani kuyiyika molunjika.
2. Chizindikiro cha electromagnetic flowmeter chikucheperachepera kapena chizindikiro chimatsika mwadzidzidzi
Zambiri mwa zolakwikazi zimayambitsidwa ndi chikoka cha sing'anga yoyezera kapena chilengedwe chakunja, ndipo cholakwikacho chikhoza kuthetsedwa chokha pambuyo pa kusokoneza kwakunja kuchotsedwa.Pofuna kutsimikizira kulondola kwa muyeso, zolephera zotere sizinganyalanyazidwe.M'madera ena opangira, chifukwa cha kugwedezeka kwakukulu kwa chitoliro choyezera kapena madzi, gulu lozungulira la flowmeter lidzamasulidwa, ndipo mtengo wake ukhoza kusinthasintha.
Kodi kuthetsa?
(1) Tsimikizirani ngati ndi chifukwa cha ntchitoyo, ndipo madzimadzi amathamanga.Panthawiyi, flowmeter imangowonetsa mkhalidwe wothamanga moona mtima, ndipo vuto likhoza kuthetsedwa palokha pambuyo poti pulsation itatha.
(2) Kusokoneza kwamagetsi komwe kumachitika chifukwa cha mafunde akunja osokera, ndi zina zotero. Onani ngati pali zida zazikulu zamagetsi kapena makina opangira magetsi omwe amagwira ntchito pamalo opangira chidacho, ndikuwonetsetsa kuti chidacho chakhazikika komanso malo ogwirira ntchito ndi abwino.
(3) Pamene payipi sichidzadza ndi madzi kapena madziwo ali ndi thovu la mpweya, zonsezi zimachitika chifukwa cha ndondomeko.Panthawiyi, katswiri akhoza kufunsidwa kuti atsimikizire kuti mtengo wamtengo wapatali ukhoza kubwerera mwakale pambuyo pa madzi odzaza kapena kuti mpweya umakhala pansi.
(4) Gulu lozungulira la transmitter ndi pulagi-mu dongosolo.Chifukwa cha kugwedezeka kwakukulu kwa payipi yoyezera pamalopo kapena madzi, gulu lamphamvu la flowmeter nthawi zambiri limamasulidwa.Ngati ndi lotayirira, flowmeter ikhoza kuthetsedwa ndipo bolodi ladera likhoza kukonzedwanso.

3. Zero point ya electromagnetic flowmeter ndi yosakhazikika
Chifukwa Analysis
(1) Chitolirocho sichimadzazidwa ndi madzi kapena madziwo amakhala ndi thovu la mpweya.
(2) Mwachidziwitso, amakhulupirira kuti palibe kutuluka kwamadzimadzi mu mpope wa chubu, koma kwenikweni pali kuyenda kochepa.
(3) The zifukwa zamadzimadzi (monga osauka ofanana madutsidwe madzi, electrode kuipitsa, etc.).
(4) Kusungunula kwa dera lazizindikiro kumatsitsidwa.
Kodi kuthetsa?
Ndikofunikira kuyang'ana ngati sing'angayo ili yodzaza ndi mapaipi komanso ngati pali thovu la mpweya mkatikati.Ngati pali thovu la mpweya, chochotsera mpweya chimatha kuikidwa kumtunda kwa thovu la mpweya.Kuyika kopingasa kwa chida kungasinthidwenso kuti ikhale yoyima.Onani ngati chidacho chakhazikika bwino.Kukana kwapansi kuyenera kukhala kochepa kapena kofanana ndi 100Ω;ma conductivity a sing'anga conductive sayenera kuchepera 5μs/cm.Ngati sing'angayo yaunjikana mu chubu choyezera, iyenera kuchotsedwa munthawi yake.Pewani kukanda chinsalu pochotsa.
