Emishini yezinzwa kagesi yezimboni, umgomo wokulinganisa we-electromagnetic flowmeter umthetho kaFaraday wokungeniswa kwe-electromagnetic.Isakhiwo se-electromagnetic flowmeter ikakhulukazi sakhiwe uhlelo lwesekethe kazibuthe, ipayipi lokulinganisa, i-electrode, igobolondo, ulwelwesi kanye nesiguquli.Ngokuyinhloko isetshenziselwa ukukala ukugeleza kwevolumu ye-conductive liquids kanye nama-slurries kumapayipi avaliwe.Kubandakanya ama-asidi, ama-alkali, usawoti kanye nolunye uketshezi olugqwala kakhulu.Lo mkhiqizo usetshenziswa kabanzi ku-petroleum, amakhemikhali, i-metallurgy, izindwangu, ukudla, ezemithi, ukwenza amaphepha nezinye izimboni, kanye nokuvikelwa kwemvelo, ukuphathwa kukamasipala, ukwakhiwa kokugcinwa kwamanzi kanye neminye imikhakha.
Enqubweni yokusebenzisa i-flowmeter ye-electromagnetic, ukwehluleka okuthile kwemishini kuzokwenzeka nakanjani.Ngokuvamile kunezinhlobo ezimbili zokwehluleka ekusebenzeni: eyodwa ukwehluleka kwensimbi ngokwayo, okungukuthi, ukwehluleka okubangelwa ukulimala kwezingxenye zesakhiwo noma izingxenye zensimbi;okwesibili, ukwehluleka okubangelwa izimbangela zangaphandle, njengokufakwa okungalungile, ukuphazamiseka kokugeleza, ukubeka kanye nokukala, njll.
Uma i-flowmeter ka-electromagnetic ihluleka, ngokuvamile sidinga ukuhlaziya ukuthi iyiphi ingxenye enephutha bese sithola ukuthi siyilungisa kanjani inkinga.
1. Amaphutha avamile we-electromagnetic flowmeter - i-electromagnetic flowmeter ayinakho ukuphuma kwesignali yokugeleza
Lolu hlobo lokwehluleka luvame kakhulu ngesikhathi sokusetshenziswa, futhi izizathu ngokuvamile ziyi:
(1) Ukunikezwa kwamandla kwethuluzi akujwayelekile;
(2) Ukuxhunywa kwekhebula nokuphuma kwebhodi lesekethe yamandla akuvamile;
(3) Ukugeleza koketshezi akuhlangabezani nezidingo zokufakwa;
(4) Izingxenye zezinzwa zonakalisiwe noma kukhona ungqimba olunamathelayo odongeni lwangaphakathi lwesilinganiso;
(5) Izingxenye zesiguquli ezilimele
Indlela yokuxazulula?
Uma lokhu kwenzeka, qala uhlole ukuthi ukunikezwa kwamandla kwethuluzi kunephutha yini, qinisekisa ukuthi ugesi uxhumekile, hlola ukuthi i-voltage ephumayo yebhodi lesekethe yokuphakela amandla ijwayelekile, noma zama ukufaka esikhundleni salo lonke ibhodi lesekethe yokuphakela amandla ukuze unqume. noma kuhle.Hlola ukuthi izintambo ziqinile futhi zixhumeke ngendlela efanele.Hlola isiqondiso sokugeleza kwamanzi futhi uketshezi olusepayipini lugcwele.Uma lungekho uketshezi kunzwa, uzodinga ukufaka esikhundleni seshubhu noma ushintshe indlela yokukhweza.Zama ukuyifaka iqonde phezulu.
2. Isignali ye-electromagnetic flowmeter iya ibancane futhi ibancane noma isignali yehla ngokuzumayo
Iningi lala maphutha libangelwa ithonya lesilinganiso sokulinganisa noma imvelo yangaphandle, futhi iphutha lingaqedwa ngokwalo ngemva kokususwa kokuphazanyiswa kwangaphandle.Ukuze kuqinisekiswe ukunemba kwesilinganiso, ukwehluleka okunjalo akukwazi ukushaywa indiva.Kwezinye izindawo zokukhiqiza, ngenxa yokudlidliza okukhulu kwepayipi lokulinganisa noma uketshezi, ibhodi lesifunda le-flowmeter lizoxegiswa, futhi inani lokukhiphayo lingase lishintshe.
Indlela yokuxazulula?
(1) Qinisekisa ukuthi isizathu sokusebenza kwenqubo, futhi uketshezi luyashaya.Ngalesi sikhathi, i-flowmeter ibonisa kuphela isimo sokugeleza ngokweqiniso, futhi iphutha lingaqedwa ngokwalo ngemva kokuphela kwe-pulsation.
(2) Ukuphazamiseka kazibuthe okubangelwa amaza aphuma ngaphandle, njll. Hlola ukuthi zikhona yini izinto zikagesi ezinkulu noma imishini yokushisela kagesi esebenza endaweni yokusebenza kwethuluzi, futhi uqiniseke ukuthi insimbi isekelwe phansi nokuthi indawo yokusebenza ilungile.
(3) Uma ipayipi lingagcwaliswa ngoketshezi noma uketshezi luqukethe amabhamuza omoya, kokubili kubangelwa izizathu zenqubo.Ngalesi sikhathi, uchwepheshe angacelwa ukuthi aqinisekise ukuthi inani lokuphumayo lingabuyela kokujwayelekile ngemva kokuba uketshezi selugcwele noma amabhamuza omoya esethulisiwe.
(4) Ibhodi lesifunda le-transmitter liyisakhiwo se-plug-in.Ngenxa yokudlidliza okukhulu kwepayipi lokulinganisa elisendaweni noma uketshezi, ibhodi lamandla le-flowmeter livame ukuxegiswa.Uma ikhululekile, i-flowmeter ingahlakazwa futhi ibhodi lesifunda lingalungiswa kabusha.
3. Iphoyinti elinguziro le-flowmeter kagesi alizinzile
Ukuhlaziywa kwembangela
(1) Ipayipi aligcwaliswa ngoketshezi noma uketshezi luqukethe amabhamuza omoya.
(2) Ngokuzithoba, kukholakala ukuthi akukho ukugeleza koketshezi empompini yeshubhu, kodwa empeleni kukhona ukugeleza okuncane.
(3) Izizathu zoketshezi (okufana nokufana okungekuhle kwe-liquid conductivity, ukungcoliswa kwe-electrode, njll.).
(4) I-insulation yesifunda sesignali yehlisiwe.
Indlela yokuxazulula?
Kuyadingeka ukuhlola ukuthi i-medium igcwele amapayipi nokuthi akhona yini ama-bubbles emoyeni phakathi nendawo.Uma kukhona amabhamuza omoya, isicoci somoya singafakwa phezulu nomfula.Ukufakwa okuvundlile kwethuluzi kungashintshwa futhi kufakwe mpo.Hlola ukuthi insimbi isekelwe kahle yini.Ukumelana okuphansi kufanele kube ngaphansi noma kulingane no-100Ω;I-conductivity ye-conductive medium akufanele ibe ngaphansi kuka-5μs/cm.Uma i-medium iqoqa ku-tube yokulinganisa, kufanele isuswe ngesikhathi.Gwema ukunwaya ulwelwesi ngesikhathi ususa.
